摘　　要：综述了环境内分泌干扰物壬基酚聚氧乙烯醚的化学性质、环境释放机制以及其对环境构成的危害,归纳了壬基酚及其短链聚氧乙烯醚(NPnEO)在膜-生物反应器(MBR)中的迁移转化规律,分析了其生物降解性和降解机理,探讨了MBR中活性污泥对其吸附能力和膜的截留能力,讨论了包括厌氧或好氧条件下的温度、水力停留时间、污泥停留时间等因素对于其降解过程的影响。Nonylphenol polyethoxylates （NPnEO） a kind of environmental endocrine disruptors,are widely used in detergents, emulsifiers and pesticide additives, etc. Its chemical property and its release mechanism and harms to the environment are simply introduced. The occurrence and fate of nonylphenol polyethoxylates （NPnEO） in Membrane bioreactor（MBR） is summarized in this paper. The biodegradation of NPnEO is analyzed. The adsorption behavior between the activated sludge and NPEO and the retention of NPnEO by membrane are discussed. The factors affecting the process of nonylphenol polyethoxylates biodegradation in anaero- bic or aerobic conditions are also discussed, such as temperature, HRT, SRT and so on.
