Abstract

Abstract

Membrane bioreactor (MBR) is a wastewater treatment process combining membrane separation technology with activated sludge process. The high removal efficiency of MBR makes it widely used, but the problems of membrane blockage and membrane pollution hinder the further popularization of MBR process. Powder activated carbon (PAC) has a high specific surface area, and strong adsorption capacity that can effectively alleviate the membrane blockage and membrane pollution during operation. By summing up the research progress of the carbon membrane bioreactor (PAC-MBR) in recent years, the influencing factors (pH, hydraulic residence time, sludge residence time, aeration volume, sludge concentration and inlet water quality) affecting MBR process were analyzed, the removal of ammonia nitrogen, BOD, COD, TOC and TN were summarized, the process effect of turbidity by PAC-MBR combined process on wastewater, and the effects of PAC-MBR process on microbial extracellular polymer (EPS), membrane contamination, TMP and microorganisms were summarized.
