[0028] like Figures 1 to 3As shown, an activated carbon adsorption filter tank includes: a cylinder, an adsorber, and an outlet weir 3.

[0034] The tank body 1 is provided with a water inlet tank 14, the lower part of which is connected to the second water inlet pipe 25, and the water inlet 11 is located at the upper part of the water inlet tank.

[0035] The upper end of the riser tube 213 is provided with a quick connector 214.

[0039] like Figure 4 As shown, an activated carbon adsorption filtration system includes: a water supply component, a compressed air component, a dehydration component, a sewage discharge component, a water outlet component, and an activated carbon adsorption filter tank.

[0040] The water supply assembly includes a main water supply pipe 41 and multiple branch water supply pipes 42; the compressed air assembly includes an air compressor 51, a compressed air tank 52, a main air supply pipe 54, and multiple branch air supply pipes 55; the dewatering assembly includes a filter 61, a carbon extraction main pipe 62, and multiple carbon extraction branch pipes 63, wherein the filter 61 may be a microfilter; the sewage discharge assembly includes a sewage discharge main pipe 71 and multiple sewage discharge branch pipes 72; and the water discharge assembly includes a water discharge main pipe 81 and multiple water discharge branch pipes 82.

[0041] The water supply branch pipe 42 is connected to the water inlet 11, the gas supply branch pipe 55 is connected to the air inlet 211, the carbon extraction branch pipe 63 is connected to the lifting pipe 213, the sewage discharge branch pipe 72 is connected to the wastewater outlet 13, and the water outlet branch pipe 82 is connected to the water outlet 12.

[0042] The water supply branch pipe 42 is equipped with a first valve 91, the gas supply branch pipe 55 is equipped with a second valve 92, the carbon extraction branch pipe 63 is equipped with a third valve 93, the sewage discharge branch pipe 72 is equipped with a fourth valve 94, and the water outlet branch pipe 82 is equipped with a fifth valve 95.

[0043] The compressed air assembly also includes a gas drying tank 53, which is connected to the compressed air tank 52 and the gas transmission main 54.

[0044] The adsorption filter tank is the core equipment of the activated carbon adsorption filtration system. The activated carbon adsorption filter tank is a ground-level type made of steel or fiberglass, with an inclined conical hopper 15 at the bottom to facilitate backwashing and complete removal of the activated carbon. The adsorbent assembly inside the tank 1 is made of PP material, while other components are made of 304 stainless steel. A stainless steel effluent weir 3 is located above the tank, which contains coal-based granular activated carbon. Each filter tank is equipped with a pneumatic valve at its inlet 11, outlet 12, and carbon washing wastewater outlet 13.

[0045] During filtration, the first valve 91 and the fifth valve 95 are opened, and the fourth valve 94 is closed. The raw water enters the first inlet pipe 23 through the inlet tank and the second inlet pipe 25. After being evenly distributed by the water distributor 24 at the bottom of the adsorber, the water flows from bottom to top through the activated carbon bed. After adsorption and filtration, the water is collected and discharged from the outlet weir 3 at the top of the tank 1.

[0046] During backwashing, valves 91, 94, and 95 are all closed. The compressed air generated by the air compressor 51 is stored in the compressed air tank 52. The compressed air in the tank is dehumidified by the gas dryer 53 and then sent to the bottom of the adsorber through the gas supply branch pipe 55. The air rises along the riser pipe 213 and lifts the activated carbon in the cone hopper 15 to the carbon washer at the top of the adsorber. After the suspended particulate matter is washed away, the cleaned carbon returns to the carbon bed through the carbon discharge port 226 by its own weight.

[0047] After the carbon washing is completed, open the fourth valve 94, and the carbon washing wastewater will be discharged from the carbon washing wastewater outlet 13. Then open the first valve 91 to perform forward washing. After the forward washing is completed, close the fourth valve 94 and open the fifth valve 95 to enter the normal adsorption filtration process.

[0048] Suspended particulate matter in the influent affects the adsorption effect of activated carbon. In order to remove the continuously accumulated suspended particulate matter in the influent and prevent carbon particles from caking and water flow from short-circuiting, each tank needs to be backwashed for 20-30 minutes every day, depending on the suspended particulate matter in the influent. Automatic rolling backwashing is also required.

[0049] After the activated carbon is saturated, the first valve 91, the fourth valve 94, and the fifth valve 95 are all closed. The saturated carbon is lifted out through the riser pipe 213 via the quick connector 214 and the external pipeline and transported to the microfilter for dewatering. The dewatered activated carbon is then subjected to further treatment, and the wastewater is discharged into the sewage equalization tank for treatment.
