　［第１実施形態］
　図１は、本発明の第１実施形態に係る水浄化システム１の構成を示す図である。なお、図１における矢印は、水の流れの向きを示している。図３乃至図６も同様である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing the configuration of a water purification system 1 according to a first embodiment of the present invention. In addition, the arrow in FIG. 1 has shown the direction of the flow of water. The same applies to FIGS. 3 to 6.

　本発明の第１実施形態に係る水浄化システム１は、制御装置１１と、クロスフロー型フィルタ１２と、ポンプ１３－１及び１３－２と、貯水タンク１４と、濃縮タンク１５と、シャワーブース２１とを含むように構成されている。 The water purification system 1 according to the first embodiment of the present invention includes a control device 11, a cross flow filter 12, pumps 13-1 and 13-2, a water storage tank 14, a concentration tank 15, and a shower booth 21. And is configured to include.

　（制御装置）
　制御装置１１は、後述する貯水タンク１４に配置されており、センシング部１０１と、制御部１０２とを備える。制御装置１１は、貯水タンク１４内の水の水質等のセンシングを行い、センシングが済んだ水を、クロスフロー型フィルタ１２に送水する。なお、制御装置１１の具体的な機能については、図２を参照して後述する。 (Control device)
The control device 11 is disposed in a water storage tank 14 described later, and includes a sensing unit 101 and a control unit 102. The control device 11 senses the water quality and the like of the water in the water storage tank 14, and sends the sensed water to the cross flow type filter 12. The specific function of the control device 11 will be described later with reference to FIG.

　（クロスフロー型フィルタ）
　クロスフロー型フィルタ１２は、クロスフロー型フィルタ１２に送水された水を、汚染物質が濃縮された水（以下、「濃縮排水」と呼ぶ）と、シャワーブース２１において使用可能なレベルに浄化された水（以下、「浄化水」と呼ぶ）とに分離させる。分離された濃縮排水は、貯水タンク１４に戻すように送水される。これにより、貯水タンク１４には汚れが濃縮された水が徐々に貯水されていく。
　ここで、クロスフロー型フィルタとは、水の流れる向きが、ろ過膜の表面に対し平行になるようにすることで、ろ過膜に送水される水に含まれる懸濁物質やコロイドが膜面に堆積する現象を抑制しながらろ過を行うフィルタの型式のことをいう。これに対して、第２実施形態及び第３実施形態で後述する全量ろ過型フィルタ１６は、ろ過膜に送水される水の全量についてろ過を行うフィルタの型式のことをいう。クロスフロー型フィルタ１２は、一般に膜面の流速が高いほど膜面への付着物質の堆積が抑制されるので、全量ろ過型フィルタ１６よりも高いろ過流束を得ることができる。

The separated concentrated drainage is sent back to the water storage tank 14. As a result, the water with concentrated contamination is gradually stored in the water storage tank 14.
Here, with the cross flow type filter, suspended matter and colloid contained in the water sent to the filtration membrane are on the membrane surface by making the flow direction of the water parallel to the surface of the filtration membrane. This refers to the type of filter that performs filtration while suppressing the phenomenon of deposition. On the other hand, the total quantity filtration type filter 16 described later in the second and third embodiments refers to a type of filter that performs filtration on the total amount of water supplied to the filtration membrane. In general, the higher the flow velocity of the membrane surface, the more the deposition of the adhesion substance on the membrane surface is suppressed, so that the filtration flux of the cross flow type filter 12 can be higher than that of the total filtration type filter 16.

　（貯水タンク）
　貯水タンク１４は、シャワーブース２１から排出された使用済みの排水を貯水するためのタンクである。貯水タンク１４に貯水されている水の量は、水量メータ１４１によって確認することができる。上述したように、貯水タンク１４には、制御装置１１が配置されている。貯水タンク１４に貯水された水は、制御装置１１によって汚染濃度が判定される。汚染濃度が所定の閾値を超えたと判定されると、貯水タンク１４に貯水されている水は、濃縮排水として貯水タンク１４から排出されて、濃縮タンク１５に送水される。
　なお、貯水タンク１４は、樹脂タンク、金属タンク、セラミックタンク、などのうち少なくとも１つから選択することができる。 (Water storage tank)
The water storage tank 14 is a tank for storing the used drainage drained from the shower booth 21. The amount of water stored in the water storage tank 14 can be confirmed by the water amount meter 141. As described above, the control device 11 is disposed in the water storage tank 14. The controller 11 determines the contamination concentration of the water stored in the water storage tank 14. If it is determined that the contamination concentration exceeds the predetermined threshold value, the water stored in the water storage tank 14 is discharged from the water storage tank 14 as concentrated drainage and sent to the concentration tank 15.
The water storage tank 14 can be selected from at least one of a resin tank, a metal tank, a ceramic tank, and the like.

　（濃縮タンク）
　濃縮タンク１５は、貯水タンク１４に貯水された水の汚染濃度が所定の閾値を超えたと判定された場合に、貯水タンク１４から排出される濃縮排水を一時的に貯水するためのタンクである。濃縮タンク１５に貯水された濃縮排水は、水浄化システム１のメンテナンスが実施された時など、所定のタイミングで廃棄される。
　ここで、濃縮タンク１５に貯水された濃縮排水は、廃棄するだけではなく再利用することもできる。なお、濃縮タンク１５に貯水された濃縮排水を再利用する手法（第５実施形態）については、図６を参照して後述する。 (Concentration tank)
The concentration tank 15 is a tank for temporarily storing concentrated drainage discharged from the water storage tank 14 when it is determined that the contamination concentration of the water stored in the water storage tank 14 exceeds a predetermined threshold. The concentrated drainage stored in the concentration tank 15 is discarded at a predetermined timing, such as when maintenance of the water purification system 1 is performed.
Here, concentrated drainage stored in the concentration tank 15 can be reused as well as discarded. In addition, the method (5th Embodiment) which reuses the concentration waste water stored by the concentration tank 15 is later mentioned with reference to FIG.

　（シャワーブース）
　シャワーブース２１は、送水された浄化水を散水するシャワーを備えるブースである。シャワーブース２１は、図示はしないが、シャワーの水量を調節するバルブと、送水された浄化水を散水するシャワーヘッドと、シャワーヘッドから散水された浄化水をシャワーブース２１の外部に排出する排水パンとを備える。シャワーブース２１で使用された水は、ポンプ１３－１を介して貯水タンク１４に送水される。 (Shower booth)
The shower booth 21 is a booth equipped with a shower for sprinkling the purified water supplied. Although not shown, the shower booth 21 has a valve for controlling the amount of water in the shower, a shower head for sprinkling the purified water supplied, and a drainage pan for discharging the purified water sprayed from the shower head to the outside of the shower booth 21. And The water used in the shower booth 21 is sent to the water storage tank 14 via the pump 13-1.

　以上のように、図１に示す第１実施形態の水浄化システムであれば、制御装置１１の制御により、過剰な汚染濃度の水をクロスフロー型フィルタ１２に送水されることがなくなるため、クロスフロー型フィルタ１２の長寿命化を実現させることが可能となる。 As described above, in the case of the water purification system according to the first embodiment shown in FIG. 1, water of excessive contamination concentration is not supplied to the cross flow type filter 12 under the control of the control device 11, so cross It becomes possible to realize long life of the flow type filter 12.

　［機能的構成］
　図２は、本発明の水浄化システム１が備える制御装置１１の機能的構成を示すブロック図である。 [Functional configuration]
FIG. 2 is a block diagram showing a functional configuration of the control device 11 provided in the water purification system 1 of the present invention.

　制御装置１１は、センシング部１０１と、制御部１０２とを備える。 The control device 11 includes a sensing unit 101 and a control unit 102.

　センシング部１０１は、各種センサで構成されており、各種センサの夫々がセンシングを行う。なお、センシング部１０１におけるセンシングの対象は特に限定されない。センシング部１０１を構成する各種センサは、例えば水圧、流量、ｐＨ、粘度、濁度、色度、臭気、全有機炭素、全無機炭素、全炭素、硝酸態窒素、亜硝酸体窒素、アンモニア態窒素、全窒素、残留塩素、全リン、電気伝導度、温度、を検知可能な少なくとも１以上から選択することができる。 The sensing unit 101 is configured of various sensors, and each of the various sensors performs sensing. The target of sensing in the sensing unit 101 is not particularly limited. The various sensors constituting the sensing unit 101 are, for example, water pressure, flow rate, pH, viscosity, turbidity, chromaticity, odor, total organic carbon, total inorganic carbon, total carbon, nitrate nitrogen, nitrite nitrogen, ammonia nitrogen Total nitrogen, residual chlorine, total phosphorus, conductivity, temperature can be selected from at least one that can be detected.

　制御部１０２は、図示はしないが、ＣＰＵ（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ）、ＲＯＭ（Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）、ＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｙ）等からなるマイクロコンピュータを主体として構成され、所定のプログラムに従って各種の処理を実行することにより水浄化システム１の全体を制御する。例えば制御部１０２は、センシング部１０１のセンシングにより得られたセンシングデータに基づいて、貯水タンク１４に貯水された水の汚染濃度が所定の閾値を超えたか否かを判定する。汚染濃度が所定の閾値を超えると、制御部１０２は、貯水タンク１４から濃縮排水を排出する制御を実行する。 Although not shown, the control unit 102 mainly includes a microcomputer including a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and the like, and executes various processes according to a predetermined program. Control the entire water purification system 1 by For example, based on sensing data obtained by sensing by the sensing unit 101, the control unit 102 determines whether the contamination concentration of the water stored in the water storage tank 14 exceeds a predetermined threshold. When the contamination concentration exceeds a predetermined threshold, the control unit 102 executes control to discharge the concentrated drainage from the water storage tank 14.

　制御部１０２においては、水浄化処理が実行される場合には、取得部１１１と、判定部１１２と、送水制御部１１３とが機能する。 In the control unit 102, when the water purification process is performed, the acquisition unit 111, the determination unit 112, and the water supply control unit 113 function.

　取得部１１１は、センシング部１０１のセンシングにより得られたセンシングデータを取得する。 The acquisition unit 111 acquires sensing data obtained by the sensing of the sensing unit 101.

　判定部１１２は、取得部１１１により取得されたセンシングデータに基づいて、貯水タンク１４に貯水された水の汚染濃度が所定の閾値を超えているか否かを判定する。なお、所定の閾値をどのように設定するかについては特に限定されず、例えばクロスフロー型フィルタ１２の浄化能力や、シャワーブース２１で使用される浄化水のレベル及び使用量等に応じて任意に設定することができる。 The determination unit 112 determines, based on the sensing data acquired by the acquisition unit 111, whether or not the contamination concentration of the water stored in the water storage tank 14 exceeds a predetermined threshold. There is no particular limitation on how to set the predetermined threshold, and it is optional according to, for example, the purification capacity of the cross flow filter 12 or the level and amount of the purified water used in the shower booth 21. It can be set.

　送水制御部１１３は、判定部１１２による判定の結果に基づいて、水浄化システム１内に水を送水する制御を実行する。具体的には、送水制御部１１３は、水浄化システム１内に配置されたポンプ１３－１及び１３－２を制御したり、貯水タンク１４の排水弁（図示せず）等を制御したりすることで、水浄化システム１内の送水を制御する。
　例えば、送水制御部１１３は、ポンプ１３－１が、水を貯水タンク１４に送水する制御を実行する。また、送水制御部１１３は、ポンプ１３－２が、クロスフロー型フィルタ１２を通過させた浄化水をシャワーブース２１に送水する制御、及びクロスフロー型フィルタ１２で浄化されなかった水を再び貯水タンク１４に送水する制御を実行する。
　また、送水制御部１１３は、判定部１１２の判定の結果、貯水タンク１４に貯水された水の汚染濃度が所定の閾値を超えたとされた場合には、貯水タンク１４の排水弁（図示せず）を開く制御を実行する。これにより、貯水タンク１４に貯水された濃縮排水が排出されて、濃縮タンク１５に送水される。 The water supply control unit 113 executes control to supply water into the water purification system 1 based on the result of the determination by the determination unit 112. Specifically, the water control unit 113 controls the pumps 13-1 and 13-2 disposed in the water purification system 1, and controls a drain valve (not shown) of the water storage tank 14 and the like. Control the water supply in the water purification system 1.
For example, the water supply control unit 113 controls the pump 13-1 to supply water to the water storage tank 14. Further, the water control unit 113 controls the pump 13-2 to supply the purified water having passed through the cross flow filter 12 to the shower booth 21, and the water that has not been purified by the cross flow filter 12 is stored in the water storage tank again. Execute control to send water to 14.
Further, when the contamination concentration of the water stored in the water storage tank 14 exceeds the predetermined threshold as a result of the determination of the determination unit 112, the water supply control unit 113 causes the drainage valve of the water storage tank 14 (not shown) Execute control to open). Thus, the concentrated drainage stored in the water storage tank 14 is discharged and sent to the concentration tank 15.

　このように、制御装置１１による送水の制御の内容は、貯水タンク１４に貯水された水の汚染濃度の閾値を、どのように設定するかによって変わってくる。
　即ち、汚染濃度の閾値を下げた場合には、汚染濃度が低い状態の水が廃棄対象として濃縮タンクに送水されることになるので、それだけクロスフロー型フィルタ１２に送水される水の汚染濃度が低くなる。これにより、クロスフロー型フィルタ１２の低コスト化や長寿命化を図ることができる。また、水が貯水タンク１４に貯水されている時間が短くなるので、貯水タンク１４の内部における細菌の繁殖を抑えることもできる。ただし、汚染濃度の閾値を下げると、廃棄対象として濃縮タンクに送水される濃縮排水の量が増えることになるので、浄化して再使用可能な水の量が少なくなる。 As described above, the content of control of water supply by the control device 11 changes depending on how the threshold value of the contamination concentration of the water stored in the water storage tank 14 is set.
That is, when the threshold value of the contamination concentration is lowered, water with low contamination concentration is sent to the concentration tank as an object to be disposed of, so the contamination concentration of the water sent to the crossflow filter 12 is It gets lower. As a result, the cost and the life of the crossflow filter 12 can be reduced. In addition, since the time in which water is stored in the water storage tank 14 is shortened, the growth of bacteria inside the water storage tank 14 can be suppressed. However, if the threshold value of the pollution concentration is lowered, the amount of concentrated drainage water to be sent to the concentration tank as the disposal target will increase, so the amount of water that can be cleaned and reused becomes smaller.

　これに対して、汚染濃度の閾値を上げた場合には、汚染濃度が高い状態の水が廃棄対象として濃縮タンクに送水されることになるので、それだけクロスフロー型フィルタ１２に送水される水の汚染濃度が高くなる。この場合、クロスフロー型フィルタ１２の浄化処理能力を高くするための高コスト化や、交換寿命の短命化の問題が生じ得る。また、水が貯水タンク１４に貯水されている時間が長くなるので、貯水タンク１４の内部における細菌の繁殖し易くなるという問題も生じ得る。しかしながら、廃棄対象として濃縮タンクに送水される濃縮排水の量が減ることになるので、浄化して再利用可能な水の量を増やすことができる。このため、例えば少量の水しか確保できないことが想定されるイベント等に好適である。 On the other hand, when the threshold value of the contamination concentration is raised, water in a state of high contamination concentration is sent to the concentration tank as an object to be discarded. Contamination concentration increases. In this case, there may be a problem of cost increase for increasing the purification processing capacity of the cross flow type filter 12 and shortening of the exchange life. In addition, since the time during which water is stored in the water storage tank 14 becomes long, there may also be a problem that bacteria can be easily propagated inside the water storage tank 14. However, since the amount of concentrated drainage water supplied to the concentration tank as the disposal target is reduced, the amount of water that can be purified and reused can be increased. For this reason, it is suitable for the event etc. which are assumed that only a small amount of water can be secured, for example.

　このように、クロスフロー型フィルタ１２のコストと、シャワーブース２１で使用する浄化水の量及び質との関係はトレードオフの関係にあるが、制御装置１１によれば、汚染濃度の閾値を任意に設定することで様々な価値基準に対応させることができる。例えば、クロスフロー型フィルタ１２のコストを抑えることが優先される場合には、制御装置１１は、汚染濃度の閾値を下げることにより、クロスフロー型フィルタ１２の低コスト化や長寿命化を図ることができる。また、シャワーブース２１で使用する浄化水の量を増やすことが優先される場合には、制御装置１１は、汚染濃度の閾値を上げることにより、浄化して再利用可能な水の量を増やすことができる。
　これにより、フィルタの単価を上昇させることなく長寿命化させることを可能とする水浄化システムを提供することができる。 As described above, there is a trade-off between the cost of the cross flow filter 12 and the amount and quality of the purified water used in the shower booth 21. However, according to the control device 11, the threshold value of the contamination concentration is arbitrary. By setting to, it is possible to correspond to various value standards. For example, in the case where priority is given to reducing the cost of the crossflow filter 12, the controller 11 lowers the threshold of the contamination concentration to reduce the cost and increase the life of the crossflow filter 12. Can. When priority is given to increasing the amount of purified water used in the shower booth 21, the control device 11 increases the amount of water that can be purified and reused by raising the threshold value of the contamination concentration. Can.
As a result, it is possible to provide a water purification system capable of prolonging the service life without increasing the unit price of the filter.

　［第５実施形態］
　図６は、本発明の第５実施形態に係る水浄化システム１の構成を示す図である。 Fifth Embodiment
FIG. 6 is a view showing the configuration of a water purification system 1 according to a fifth embodiment of the present invention.

　本発明の第５実施形態に係る水浄化システム１は、上述の第１実施形態乃至第４実施形態に含まれている濃縮タンク１５を含まない構成となっている。第５実施形態では、濃縮タンク１５の代わりに、濃縮排水を別プロセスで浄化するための浄化装置３１を含むように構成されている。
　即ち、第１実施形態乃至第４実施形態では、貯水タンク１４から排出された濃縮排水は、濃縮タンク１５に貯水されたうえで廃棄される。しかしながら、貯水タンク１４から濃縮排水を排出する基準となる汚染濃度の閾値が低く設定されている場合には、汚染濃度が低い濃縮排水が濃縮タンクに貯水されることとなる。この場合、上述したように、クロスフロー型フィルタ１２や全量ろ過型フィルタ１６の長寿命化を図ることができるが、濃縮タンクに貯水される濃縮排水の量が増えることになる。これにより、シャワーブース２１に送水される浄化水の水質を向上させることはできるが、シャワーブース２１に送水される浄化水の量は少なくなる。 The water purification system 1 which concerns on 5th Embodiment of this invention becomes a structure which does not contain the concentration tank 15 contained in the above-mentioned 1st Embodiment thru | or 4th Embodiment. In the fifth embodiment, instead of the concentration tank 15, a purification device 31 for purifying concentrated drainage in another process is included.
That is, in the first to fourth embodiments, the concentrated drainage discharged from the water storage tank 14 is stored in the concentration tank 15 and then discarded. However, if the threshold value of the contamination concentration, which is a reference for discharging concentrated drainage from the water storage tank 14, is set low, concentrated drainage with low contamination concentration is stored in the concentration tank. In this case, as described above, although it is possible to prolong the life of the crossflow filter 12 and the total quantity filter 16, the amount of concentrated drainage stored in the concentration tank is increased. Thus, the quality of the purified water supplied to the shower booth 21 can be improved, but the amount of purified water supplied to the shower booth 21 is reduced.

　そこで、貯水タンク１４から排出された濃縮排水を浄化して再利用する。具体的には、図６に示すように、貯水タンク１４と濃縮タンク１５との間に、浄化装置３１を含む構成とする。これにより、貯水タンク１４から排出された濃縮排水の少なくとも一部を再利用可能とする別工程の浄化処理を行ったうえで、浄化された水を貯水タンク１４に戻すことができる。また、浄化されなかった水は、浄化装置３１から濃縮タンク１５に排出される。
　これにより、シャワーブース２１に送水される浄化水の水質を所定レベルで維持させながらシャワーブース２１に送水される浄化水の量を増やすことができる。 Therefore, the concentrated drainage discharged from the water storage tank 14 is purified and reused. Specifically, as shown in FIG. 6, a purification device 31 is included between the water storage tank 14 and the concentration tank 15. As a result, it is possible to return the purified water to the water storage tank 14 after performing the purification process of another process that makes it possible to reuse at least a part of the concentrated drainage discharged from the water storage tank 14. In addition, water that has not been purified is discharged from the purification device 31 to the concentration tank 15.
This makes it possible to increase the amount of purified water supplied to the shower booth 21 while maintaining the quality of the purified water supplied to the shower booth 21 at a predetermined level.

　ここで、浄化装置３１における浄化処理の具体的手法は特に限定されない。例えば、微生物による分解、オゾン殺菌、凝集沈降、固形化等、あらゆる手法を用いることができる。具体的には、微生物の分解により浄化を行う場合には、濃縮タンク１５に貯水された濃縮排水の汚染濃度が高い方が分解を促進させることができるので、第５実施形態のように浄化装置３１を設けることで濃縮排水をさらに濃縮するメリットがある。また、固形化により浄化を行う場合には、固形化された汚染物質を燃料として再利用することも可能となる。 Here, the specific method of the purification process in the purification device 31 is not particularly limited. For example, any method such as decomposition by microorganisms, ozone sterilization, aggregation sedimentation, solidification, etc. can be used. Specifically, when the purification is performed by the decomposition of the microorganism, the higher the contamination concentration of the concentrated drainage stored in the concentration tank 15 is, the more the decomposition can be promoted. Therefore, as in the fifth embodiment, the purification apparatus By providing 31 there is a merit to further concentrate the concentrated drainage. In addition, when purification is performed by solidification, it is also possible to reuse solidified contaminants as fuel.

In the case of the shower booth 21 employed in the above-described embodiment, components contained in the drainage can be predicted such as sebum, soaps, hair and the like. Therefore, variations in the number and arrangement of the cross flow type filter 12, the water storage tank 14, the total quantity filter type filter 16, and the water storage tank 17 can be arbitrarily selected accordingly. Similarly, when a washing machine, a toilet, or a dishwashing dryer is selected as the means of use in the present invention, the number of the cross flow type filter 12, the water storage tank 14, the total filtration type filter 16, and the water storage tank 17 Variations of the arrangement can also be arbitrarily selected according to the selected means of use. As a result, a large amount of purified water can be prepared, and a large amount of waste water can be treated, so that stable supply of purified water can be realized. For example, a place where a large number of people are expected to use the shower booth 21 and other devices, such as campsites, event venues, evacuation sites in the event of a disaster, trailer houses, beaches, etc. Can be installed.

　また、図６に示す水浄化システム１の構成は例示に過ぎない。図６では、シャワーブース２１から排出された使用済みの排水は、貯水タンク１４に貯水された後に、濃縮排水として浄化装置３１に送水される構成となっている。ただし、この構成に限定されず、例えば、図示はしないが、シャワーブース２１から排出された使用済みの排水が、直接、浄化装置３１又は濃縮タンク１５に送水され、その後、貯水タンク１４に貯水されて浄化される構成としてもよい。 Moreover, the structure of the water purification system 1 shown in FIG. 6 is only an illustration. In FIG. 6, the used waste water discharged from the shower booth 21 is configured to be sent to the purification device 31 as concentrated waste water after being stored in the water storage tank 14. However, the present invention is not limited to this configuration. For example, although not shown, the used waste water discharged from the shower booth 21 is directly supplied to the purification device 31 or the concentration tank 15 and thereafter stored in the water storage tank 14 May be purified.

　また例えば、図２の機能的構成は例示に過ぎず、特に限定されない。
　即ち、上述した一連の処理を全体として実行できる機能が水浄化システム１に備えられていれば足り、この機能を実現するためにどのような機能ブロックを用いるのかは特に図２の例に限定されない。また、機能ブロックの存在場所も、図２に特に限定されず、任意でよい。 Also, for example, the functional configuration of FIG. 2 is merely an example, and is not particularly limited.
