As shown in Figure 1, the counter-flow filter filtration tank 100 according to the present invention, the body 110 is formed with a storage space therein; Wastewater inlet 111 formed in the main body 110 so that the wastewater flows; A backflow filter 120 installed to filter while the wastewater introduced through the wastewater inlet 111 flows upward; A purified water outlet 112 formed through the upper side of the counterflow filter 120 so that the purified water is discharged while passing through the counterflow filter 120; A sludge deposit 130 formed under the backflow filter 120; It is installed on the upper side of the backflow filter 120, the filter cleaning device 140 for radiating a high pressure fluid toward the backflow filter 120; is configured to include.

Basically, while the wastewater introduced through the wastewater inlet 111 is flowed upward, the wastewater is purged by the backflow filter 120 and then discharged through the purified water outlet 112.

Further, when the backflow filter 120 is clogged by contaminants during the clarification operation, as shown in FIG. 3, the high pressure fluid such as air, water, etc. is introduced into the backflow filter 120 by the filter cleaning device 140. By spinning on the upper side, the backflow filter 120 can be cleaned.

That is, the backflow filter type filtration tank 100 according to the present invention can clean the wastewater while cleaning the backflow filter 120 at any time by the filter cleaning device 140, so that the size of the backflow filter 120 is not necessarily large. It does not matter, and therefore, the overall size of the purification device can be reduced, and the vehicle can be transported sufficiently, which is very suitable for the purification of nonpoint source.

The filter cleaning device 140 may be implemented by a structure in which the high pressure fluid pressurized by the compressor 141 or the like is radiated to the backflow filter 120 by the nozzle structure or the like.

The filter cleaning device 140 may be manually controlled, but the wastewater inflow load detection unit 200 installed in front of the wastewater inlet 111 to detect the load of the wastewater flowing into the wastewater inlet 111. ; It is more preferable to be controlled by the structure further comprising; filter cleaning device control unit 210 for controlling the filter cleaning device 140 by the information detected by the wastewater inflow load detection unit 200.

The wastewater inflow load detection unit 200 detects the load by a method of measuring the pressure of the inflowing wastewater and the like, and the increase in the load means that the degree of clogging of the backflow filter 120 by the contaminant increases, and thus a certain value. When the above load is detected, the filter cleaning device 140 controls the filter cleaning device 140 to operate.

In response to the information detected by the wastewater inflow load detection unit 200, the wastewater inflow control unit 220 for controlling the opening and closing of the wastewater inflow unit 111; By controlling to close the wastewater inlet 111, only the cleaning operation of the backflow filter 120 may be performed in a state where no new wastewater is introduced.

This rotational flow generating means may be implemented by the addition of a rotating device such as a fan (fan), as shown in Figure 2, wastewater flowing through the wastewater inlet 111 is in the center of the body 110 It can be implemented without the addition of a separate device by allowing it to be introduced with eccentricity.

A sludge deposit 130 is formed at the bottom of the backflow filter 120. In order to easily discharge the sludge S deposited therein, a sludge discharge part 131 that can be opened and closed at the bottom of the main body 110 is provided. It is preferable to take the formed structure.
