Operation is prepared at first as shown in Figure 7, and filtration members (71)～(73) are arranged on the filter (2).At this moment, in the hypomere bucket (41) of filter element (4), take in the biofiltration material filtration members (71) such as (シ Port ラ Star ケ ス (siporax)) that the breeding anaerobic is filtered bacterium, carry out biofiltration.And then in stage casing bucket (42), take in the filtration members such as biological ball (72) that the breeding aerobic filters bacterium, carry out biofiltration.And then in aproll dish (43), take in filtration members (73) such as wool, active carbon via trellis plate (44), carry out physical filtering.

As mentioned above, stride sidewall upper and be provided with at the sidewall of tank (1) and overflow device (5).At this moment, the interior water portion (51) of groove of overflowing device (5) is dipped into assigned position by the water in the tank (W), and the water (W) in the tank flow in the interior water portion (51) of groove via limbers (511), retains the amount of regulation.

Have again, overflow physical filterings such as also having taken in the sea in the groove of device (5) in the water portion (51) with filtration members (omission accompanying drawing).

In addition, at filter (2) with overflow flexible pipe (11) (12) is set between the device (5).That is, the end, inflow side that will import flexible pipe (11) is connected with the importing flexible pipe connector (521) that overflows device (5), simultaneously the end, outflow side is connected with the importing flexible pipe connector (341) of filter (2).Further the end, inflow side with drain hose (12) is connected (342) connection connection with the drain hose of filter (2), simultaneously, the end, outflow side is connected with the drain hose connector (523) that overflows device (5).

Secondly, inject water (W), this water level is reached hang down the position of some than the water level of water portion (51) in the groove to the water portion (52) of overflowing device (5) groove outside that is arranged on the tank sidewall.Then, via suction pipe (556) from the air entry (555) of siphon pipe (55) with the complete sucking-off of air in the siphon pipe (55) after, make air-breathing (555) become suction condition or air-tight state.Thus, be full of water (W) in the siphon pipe (55), utilize siphonage, a spot of water (W) flows to water portion (52) outside the groove by siphon pipe (55) water portion (51) in groove, after the water level of two water portions (51) (52) equates, stops to supply water (W).

In addition, outside groove, be provided with in the water portion (52) and hide sound cover (57), with the full week sealing of discharger (54).

Secondly, in the casing (20) of filter (2), inject the water (W) of ormal weight.At this moment, water (W) retained the height that the Anaerobic Bacteria of having taken in the casing (20) is flooded with the lower end bucket (41) of filtration members (71).Will water filling (W) in casing (20), as long as water filling (W) in tank (1).That is,, the water level of tank (1) is risen by water filling (W) in tank (1), therefore, with the rising of its water level, in overflowing device (5) by siphon pipe (55) water portion (51) water portion (52) water supply to groove outside in the groove.And then water portion (52) supplies water (W) outside groove, water level is risen after, water (W) flows into from the upper end open portion of discharger (54), supplies in the casing (20) of filter (2) by importing flexible pipe (11).Like this, by in tank (1), supplying water, water is supplied in the filter (2).

After such operation is ready to complete, the operation of beginning tank system.That is, drive the excavationg pump (35) of filter (2), the while is to magnesia magnesium chloride mixture (66) air feed of protein filter (6).

In view of the above, in the casing (20) of filter (2), by excavationg pump (35) water (W) is transported to discharge pipe (351), these water (W) are further supplied with to the discharge pipe that overflows device (5) (56) through drain hose (12).Supply is discharged to tank (1) from nozzle (513) to the water (W) of discharge pipe (56).

Like this, water (W) is supplied with in tank (1), the water level of tank (1) is risen after, along with its water level rises, the water level that overflows water portion (51) in the groove of device (5) also rises.Thus, the water (W) in the tank supplies to water portion (52) outside the groove by siphon pipe (55) water portion (51) in groove.And then this water (W) flows into discharger (54), supplies with in the casing (20) of filter (2) through importing flexible pipe (11).
