1. Experimental purpose: The
membrane bioreactor sewage treatment device is an experimental device of an integrated membrane bioreactor. The membrane bioreactor is a new sewage treatment process produced by the organic combination of membrane technology and sewage biological treatment technology. Its production and development are the inevitable result of the application and development of these two types of knowledge. The cross-disciplines of membrane technology and sewage biological treatment technology have opened up a new field of sewage treatment technology research and application. Through this experiment, we hope to achieve the following goals:
1. Understand the structure and working principle of the membrane bioreactor;
