摘　　要：膜生物反应器(MBR)是一种新型高效的污水处理工艺,但MBR中膜污染问题限制了该技术的大规模推广应用。从MBR系统运行条件入手,通过实验方式定性分析了曝气强度强弱、抽停时间占比与膜污染的关系。实验得出对应工况下,最佳曝气强度为0.4 m3/(m2·h)和最佳抽停时间比4:1。最后,将优化的运行条件应用于工程实际,经过3个月的正常运行,该MBR系统膜污染控制效果显著。Membrane Bioreactor （MBR） is a new and efficient wastewater treatment process, but the fouling restricts the large-scale popularization and application of the technology.This paper qualitativelyanalyze the relationship between the membrane fouling and theoperation conditions of MBR system such as the aeration intensity andon/offratiothrough the experiments.The experiments put forward the best aeration intensity is 0.4 m^3/（m^2· h） and the best on/off ratio is 4：1. Finally, the optimal operating condition is applied to the engineering practice. After three months of normal operation, the effectofmembrane fouling controlling is remarkable.
