Description
The utility model relates to the device of disposing of sewage, particularly a kind of pressurization biological activated carbon method device of disposing of sewage.Belong to technical field of sewage.
Development is efficient, less energy-consumption, biochemical treatment novel process that floor space is little are one of major subjects of sewage Study on Biochemical Treatment always, and one of them main approach is to improve concentration and the activity of microorganism in the biochemical reactor.
The aerobic biochemical facture is widely used in the organic sewage process field at present, is the reasonably treatment process of generally acknowledging, still, the oxygen delivery capacity of tradition method for supplying oxygen has certain limit, the BOD volumetric loading is lower, and treatment facility is huge, is difficult to satisfy the requirement of high concentration organic sewage to oxygen supply.In order to reach the purpose of oxygen high speed transfer, pure oxygen aeration, deep well aeration activated sludge process have been set up since the seventies abroad in succession.Pure oxygen aeration, deep well aeration have all improved oxygenation capacity to some extent, but the easy seepage of deep well aeration pit shaft, polluted underground water; Pure oxygen aeration device complexity, operating cost height, therefore domestic seldom use.
Learn that from document the nineties, China scientific and technical personnel began to adopt the pressurized aeration biological oxidation process, by pressurize, forced oxygenation, and dissolved oxygen content is obviously improved, also improved the processing efficiency of organic sewage significantly.A large amount of researchists have carried out mechanism research to the pressurization biological oxidation process, and the pressurization biological contact oxidation process also progressively begins to be used to handle organic sewage.But the problem that exists is the control of pressurization can not be realized continuously, mainly is batch process, does not relate to the automatic control and the continous processing system of pressure in the document.
The biological activated carbon method is the sewage water treatment method that grows up the seventies.Organic pollutant can be divided into easy degraded and difficult degradation two classes by its biodegradation character; usually gac is better to the organism absorption property of difficult degradation; hardly degraded organic substance at first is attracted to activated carbon surface; and easily biodegradable organics is by biological degradation, because gac to the absorption of hard-degraded substance, makes increase the duration of contact of microorganism and these materials; secular contact; make microorganism obtain domestication, also improved the removal effect to hardly degraded organic substance simultaneously, gac is also regenerated simultaneously.Nowadays the biological activated carbon method is used widely in China municipal sewage plant and many industrial sewage treatment project.
The physical adsorption that pressurization biological activated carbon method integrates biological degradation and gac can be handled difficult-degradation organic sewage quickly and efficiently.The report of pressurization biological activated carbon method processing organic sewage seldom has human pressurization gac biomembrance process to handle the DSD organic sewage, has obtained comparatively ideal result, the pressurizing device that adopts is simple single-column shape cylinder, but the consumption of gac is big, and the cost height easily stops up.
The applicant also carried out the work of single-column shape device experiment, be full of granular carbon in the whole cylinder, activated carbon dosage is big, under the effect of pressure and air-flow, the fragmentation of activated carbon granule causes whole device latch up phenomenon serious, the gac that contains a large amount of pulverizing in the water after the processing, also need to carry out sedimentation and filtration, make sewage treatment process complicated more, cost also improves relatively.
The purpose of this utility model provides a kind of pressurization biological activated carbon organic sewage treatment unit, and the activated carbon dosage of this device is little, can reduce cost, and prevents to stop up, and has realized the automatic control of pressure.
The utility model is that a kind of pressurization biological activated carbon method is handled the organic sewage device.The utility model Fig. 1 comprises withstand voltage water pump 3, withstand voltage air pump 4, air flowmeter 5, check valve 6, ball valve 7, magnetic valve 9, pressure controller 10, tensimeter 11, pressured column 8, normal pressure post 12, filtering net 13, water inlet bend pipe 14, retaining plate 15.Adopt pressurization to combine with the normal pressure second-stage treatment, the double-deck column structure of the built-in newel of reaction column in the device, can reduce activated carbon dosage, shorten the residence time, the pressurization biological activated carbon post high concentration organic sewage of can under high-solubility oxygen, the very fast state of biochemical reaction speed, degrading.Pressure-controlling is by the pressure controller realization that matches with magnetic valve.Normal pressure biological activated carbon post can be realized the advanced treatment of organic sewage, and the outer water of newel can static layering, and throw out can be discharged by the bottom.The newel top is with filtering net, can prevent particle outflows such as gac; The fine particle gac that penetrates filtering net of partial crushing can play the processing effect of common biological activated carbon method; Water inlet, intake valve all are designed to check valve, prevent that gas-liquid from flowing backwards, and water inlet, inlet pipe muzzle filtering net prevent to stop up, and adopt the elbow water inlet, and the anti-clogging plug performance is better.
Advantage of the present utility model:
1, adopt the second-stage treatment of pressurization and normal pressure biological activated carbon method, can be to the high density difficulty
The degraded organic sewage carries out advanced treatment.
2, establish newel in the cylinder, reduced the consumption of gac, reduce cost, handle and imitate
The rate height.
3, the newel top is with filtering net, has reduced the carry-over loss of gac, prevents to block up
Plug.
4, the supporting use of pressure controller and magnetic valve can be controlled pressure automatically, and presses
Power is adjustable continuously.
5, water inlet, intake valve adopt check valve, can prevent that gas-liquid from flowing backwards, and be safe and reliable.
6, water-in is a bend pipe, and water inlet, inlet mouth all are with filtering net, prevents to stop up.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is sectional views of the utility model pressured column and normal pressure post.
The utility model is described in further detail with reference to accompanying drawing 1～Fig. 2.
Among Fig. 1, pressurization cylinder 8 is with normal pressure cylinder 12 and fills biological activated carbon in the newel, and the newel top is with filtering net 13; The pressure of pressurization cylinder 8 is controlled by pressure controller 10 and magnetic valve 9, and pressure is adjustable continuously, can choose at random optimum pressure; Water inlet, air input is all adjustable, can select optimum gas water ratio, and check valve 6 can prevent that air water flows backwards in the newel; Air pump 4 is withstand voltage air pump.The sewage of sump 1 through under meter 2 by withstand voltage water pump 3 suction newels in, withstand voltage air pump 4 is sent into air, observes tensimeter 11 and regulates air flow quantity by air flowmeter 5, and sewage is spilled over to column jacket by newel 8 tops, after water is filled to water outlet, just can discharge.Current can precipitate and deepen processing when column jacket, throw out can be discharged by ball valve 7.Sewage after the pressure treatment enters normal pressure newel 12 via magnetic valve 9, proceeds the normal pressure in-depth and handles.In order to make full use of the processing space of column jacket, the water outlet of normal pressure post is located at the cylinder lower end by last, and precipitation can at first be discharged.
