Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

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 vibrator 121 mounted to vibrate the backflow filter 120; 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.

In addition, when the backflow filter 120 is clogged by contaminants during the clarification operation, as shown in FIG. 4, 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.

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 configured to radiate high pressure fluid when needed by manual operation, but it is more preferable to intermittently pressurize the high pressure fluid by installing a separate intermittent fluid spinning device 142.

The intermittent fluid spinning device 142 may be implemented by mounting a solenoid valve 142a on the fluid supply pipe 1 so as to repeatedly open and close the intermittent driving.

2 is an embodiment of the intermittent fluid spinning device 142, when water introduced through the water supply unit 1a formed in the fluid supply pipe 1 is configured to be radiated at high pressure by the high pressure air supply unit 1b, It shows a configuration to open and close the air supplied by the high-pressure air supply (1b) by the solenoid valve 142a.

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.

Discharge of the sludge (S) through the 131 may occur together.

The backflow filter 120 may be any structure as long as the structure allows the wastewater to be purified by backflow. However, the filter mounting part 150 installed horizontally in the core portion of the main body 110 so as to isolate the internal space of the main body 110 up and down. In the case in which the backflow filter 120 is mounted on the filter mounting hole 151, the internal space of the main body 110 is separated up and down, thereby preventing the mixing of the waste water and the purified water.

Further, when the backflow filter 120 has a structure mounted to protrude downward from the filter mounting unit 150, as shown in FIG. 1, not only the bottom surface of the backflow filter 120 but also the side surface from the side surface of the backflow filter 120. Purification of the incoming wastewater can be carried out at the same time, thereby improving the purification efficiency.

In addition, according to the nature of the waste water and the purpose of the purification, as shown in FIG. 5, a plurality of filter mounting holes 151 are formed in the filter mounting unit 150, and a counter flow filter (for each filter mounting hole 151). 120 may be mounted.

Examples of organic pollutants include organic components, oil materials having a higher density than water, heavy metal materials such as lead and zinc, and calcium chloride used as a snow removing agent in winter.

In the case of organic substances and oil substances, it can be removed by pearlite, granular activated carbon, vegetable lignin, etc., and in the case of heavy metals, it can be removed by zeolite, cation exchange resin, chitosan, etc. do.

The sludge discharged from the sludge discharge part 131 of the counter flow filter type filtration tank 100 may be stored as it is and discarded in another place, but it is more efficient to carry it after minimizing the volume by dehydrating it again by a separate configuration. to be.

6 and 6, the sludge storage tank 500 for storing the sludge discharged from the sludge discharge unit 131; It is more preferable to take the configuration further including; a dewatering tank 600 for discharging the dewatered sludge after receiving sludge supplied from the sludge storage tank 500.
