Problems solved by technology

[0007] Although the above-mentioned patents treat sewage through the multi-layer biofilm on the membrane rack, and realize the function of purifying sewage, when the sewage is treated in the treatment system, only the biofilm treatment method is used, and the treatment method is single. Among them, The sewage may also contain other solid debris, etc. After a long time of filtration, the debris will accumulate in the biofilm and affect the work of the biofilm

Abstract

The invention discloses a multilayer biological membrane sewage treatment system, and belongs to the technical field of sewage treatment. The system comprises a first conveying pipe, a second conveying pipe, a first treatment box and a second treatment box. A first sealing assembly is arranged in the first conveying pipe; a second sealing assembly is arranged in the second conveying pipe; a filtering assembly and a stirring assembly are arranged in the first treatment box; an activated carbon filter layer and a biological membrane filter layer are arranged in the second treatment box. The sewage is conveyed into the first treatment box through the first conveying pipe and is sequentially treated by the filtering assembly and the stirring assembly and then enters the second treatment box through the second conveying pipe and is sequentially treated by the activated carbon filter layer and the biological membrane filter layer; the three first water inlet pipes and the three second outlets are sequentially and intermittently opened under the action of the first sealing plate and the second sealing plate, and the processes of water inlet, filtering, stirring, conveying to the second filtering box and the like can be conducted at the same time in cooperation with work of the stirring assembly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multilayer biofilm sewage treatment system. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Various fields are also increasingly entering the daily life of ordinary people. [0003] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and organic substances, i...
