Domestic sewage treatment device
With the increase of environmental background values, stricter pollutant discharge standards, and shortage of water resources, membrane treatment technology has played an increasingly important role. MBR membrane bioreactor is an efficient combination of membrane separation technology and biological treatment method. It combines the traditional aeration tank of traditional sewage treatment with the second settling tank and replaces all the process facilities of the third-stage treatment. Reduce land area and save land investment. Membrane technology and process have the characteristics of small area, short construction period, stable operation, and good effluent water quality. They are widely used in pure water production, seawater desalination, and advanced treatment and reuse of sewage.
With the increase of environmental background values, the stricter standards for pollutant discharge and the scarcity of water resources have made the membrane treatment technology more and more important. MBR membrane bioreactor is an efficient combination of membrane separation technology and biological treatment method. It combines the traditional aeration tank and the secondary sedimentation tank into one, and replaces all the processing facilities of the tertiary treatment. Reduce floor space and save land investment. Membrane technology and technology have the features of small area, short construction period, stable operation and good water quality, and are widely used in the deep treatment and reuse of domestic sewage.
