Anaerobic reactors are usually used for high-concentration organic wastewater. The most important thing about anaerobic reactors is how to deal with the large amount of high-concentration organic wastewater brought about by production development. Therefore, it is very necessary to develop anaerobic processes with more optimized technology and economy. Anaerobic wastewater treatment technology has become increasingly mature, and the current anaerobic reactors usually have the advantages of large microbial biomass and good internal circulation mass transfer effect. The purpose of treatment includes achieving general standard emissions and reusing the treated wastewater to achieve the dual goals of saving water and controlling pollution.

Then the sludge will enter the sludge gathering plate 7 and be transferred to the reflow trough. The sludge flows along the reflow trough to the sludge bed 8, and the sludge discharge component 9 will discharge the sludge. The moving motor 907 will move on the serrated groove, thereby driving the compression box 902 to move. After the compression box 902 moves, the internal sweeping roller 908 rotates, and the cleaning brush on the sweeping roller 908 will clean the sludge and send the sludge into the storage box 903. In order to prevent the accumulated sludge from affecting the normal functioning of the anaerobic molecules and anaerobic microorganisms, the expansion motor 10 will drive the expansion agitator 11 to rotate to break up the sludge in the sewage. Then the biogas will enter the waste gas recovery cylinder 12 and be discharged under the action of the recovery pump.
