Currently, such devices have shaped products. The membrane bioreactor has the following advantages: the MBR process has the advantages of good effluent quality, easy control of process parameters, compact equipment, small occupied area and easy automatic control and management, and simultaneously has the problems like other processes, mainly the problem of membrane pollution, which is mainly attributed to the external pollution of the membrane, namely the adsorption of organic matters on the membrane surface, the precipitation of indissolvable inorganic matters on the membrane and the adhesion of microbial cells on the membrane surface, and the problem of membrane pollution is one of the main reasons influencing the popularization of the technology at present.
