Design of 300m ³ MBR domestic sewage treatment Project

Abstract

In this paper, the principle of membrane bioreactor (MBR) is introduced, the technical advantages compared with conventional wastewater bioreactor (MBR) are expounded, and the limitation factors of MBR technology are put forward. According to the parameters of sewage treatment, the data such as domestic sewage quality are consulted and calculated. In accordance with the laws and regulations of relevant countries and localities, the domestic sewage treatment project of 300 m3 membrane bioreactor was designed and the size of the membrane bioreactor facility was calculated. In view of the economic, environmental and other benefits, choose the best design scheme. The wastewater treated by the membrane biological processor can meet the needs of G B 18918-2002) A class A standard. In the end, the development history of membrane bioreactor process is introduced, the application status and market value of membrane bioreactor in wastewater treatment are summarized, and the future research direction of membrane bioreactor process is discussed. The breakthrough and development of membrane bioreactor technology in the future are prospected.
