Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an efficient sewage treatment system based on an MBR membrane. Background technique [0002] With the improvement of centralized batch processing efficiency of large urban sewage plants and industrial wastewater treatment plants, a large number of scattered and miniaturized sewage discharges such as the vast number of small and medium-sized towns, rural areas, ships, and tourist attractions have become important sources of water pollution in my country. Due to its unique sewage discharge and distribution characteristics, it has become an urgent need to develop and promote a small, integrated and efficient sewage treatment equipment. [0003] MBR is a new type of efficient sewage treatment and reuse technology that organically combines membrane separation technology with traditional sewage treatment processes. It is regarded as the "best practical technology" in the world ...
