Flow bending type anaerobic tank

Abstract

A flow bending type anaerobic tank mainly comprises a tank body, a water inlet and a water outlet. The tank body is a cuboid, one side of the tank body is connected with the water inlet, the other side of the tank body is connected with the water outlet, and an anaerobic tank body, an aerobiotic tank, a settling tank and a disinfection tank are sequentially arranged on the side, close to the water inlet, of the tank body. The anaerobic tank body is a multi-compartment anaerobic tank body and is divided by a plurality of sets of flow bending plates. The anaerobic tank has the advantages of being good in hydraulic condition, high in biological solid carrying and retaining capacity, good in microbial population distribution, simple in structure, stable in operation and the like, a stable treatment effect can be obtained accordingly, and therefore it is guaranteed that all indexes in final effluent reach the standard.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a baffled anaerobic tank. Background technique [0002] Integrated sewage treatment equipment is widely used in sewage treatment, especially domestic sewage treatment, but the anaerobic pool (some called anoxic pool) in the equipment is always a problem, because the backflow of aerobic end mixture and backflow It is difficult to fully mix the sludge with the influent in the anaerobic tank of the existing equipment, which is one of the keys to ensure that the final effluent index meets the standard. [0003] Among the existing equipment, some use perforated pipes for water distribution, and the returning aerobic end-mixed liquid and returning sludge are mixed in the perforated pipes, and the water distribution holes are easily blocked; some use aeration to mix, while aeration Oxygen will be brought in, so that the purpose of anaerobic or hypoxic can not be achieved.
