Technical principles and classification of membrane bioreactors

1.1 Basic principles of membrane bioreactor technology

        Membrane bioreactor technology has absorbed the advantages of biological treatment on the basis of membrane separation technology. Compared with traditional technical methods, it has more advantages in sewage treatment, improving the conversion rate of sewage and is currently an efficient sewage treatment system. Membrane bioreactor is the core of membrane bioreactor technology, and its structure mainly includes extraction reactor, aeration device, and membrane separation device. Here, we should mainly mention membrane separation reactors, which have biological characteristics. During operation, membrane bioreactors can be classified into different types based on the different positions of the biofilm. The results of practical investigations show that membrane bioreactors have extremely strong sewage treatment capabilities and significant effects, and are highly favored by domestic and foreign sewage treatment departments.

1.2 Classification of membrane bioreactor technology

        The types of membrane bioreactors in membrane bioreactor technology can be divided into three types: membrane separation bioreactors, membrane aeration bioreactors, and extraction membrane bioreactors. Among them, membrane separation bioreactors can be divided into two types according to the position of the membrane: split membrane bioreactors and integrated membrane bioreactors; According to whether it is aerobic, it can be divided into aerobic membrane bioreactor and anaerobic membrane bioreactor.
