The combined membrane biological reaction device provided by the invention is used for treating sewage.

Description

technical field [0001] The invention relates to a composite membrane bioreaction device, in particular to a composite membrane bioreaction device for micro-polluted water source water treatment. Background technique [0002] At present, in the field of sewage and wastewater treatment, membrane bioreactors have been rapidly developed worldwide and have become one of the most popular and efficient sewage treatment technologies. However, due to the relatively low organic load of slightly polluted source water and the Membrane fouling and other problems in the bioreactor itself have limited the application of the membrane bioreactor in the field of micro-polluted water treatment. The existing membrane bioreactors have poor decontamination effect on slightly polluted water, serious membrane pollution, and short service life of the membrane components. Contents of the invention [0003] In order to solve the problems that existing membrane bioreactors have poor decontamination ...
