摘要

摘要: 膜生物反应器（MBR）是将膜分离技术与活性污泥法相结合而形成的废水处理工艺。由于MBR具有较高的去除率使其被广泛地应用于废水处理中，但是膜堵塞和膜污染问题依旧是阻碍MBR工艺进一步推广的主要原因。颗粒活性炭（PAC）具有高的比表面积，其较强的吸附能力可有效地缓解MBR工艺运行过程中膜堵塞和膜污染问题。通过总结近年来对膜碳生物反应器（PAC-MBR）的研究进展，分析了影响MBR工艺的影响因素（pH、HRT、SRT、曝气量、SS），综述了PAC-MBR联合工艺对废水中氨氮、BOD₅、COD、TC、TN、浊度的处理效果。

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.
