[0001] The utility model relates to the technical field of sewage treatment, in particular to an integrated MBR treatment device. Background Art

[0002] Domestic sewage mainly refers to the discharged water generated by various kitchen waters, washing waters and toilet waters used in human life, and most of them are non-toxic inorganic salts.

[0003] At present, the mainstream technical means for decentralized domestic sewage treatment in China are mainly integrated devices, and the processes of the devices include the A2O process of the activated sludge method, the biological rotating disk of the biological membrane method, the contact oxidation method, etc.

[0004] For the MBR membrane method for sewage treatment, since the MBR membrane module is usually designed as an integral part of the sewage treatment system, its installation position and fixing method are carefully designed to ensure the stability and operation efficiency of the system. Therefore, disassembling the membrane module requires untying complex connection and fixing devices, which increases the operation difficulty. The membrane filaments or membrane sheets in the MBR membrane module are usually densely arranged to form a large-area filtering surface. Although this design improves the filtering efficiency, it also makes the structure of the membrane module compact and difficult to directly disassemble. Therefore, a new integrated MBR treatment device is proposed to solve the above problems. Summary of the Utility Model
