【摘要】 膜生物反应器在污水处理中的应用范围和规模虽然不断增加,然而,膜污染严重阻碍了膜生物反应器技术的推广应用。作者从膜的性质、料液性质以及膜分离的操作条件三个方面分析了膜污染的成因和膜污染过程,系统论述了膜污染在国内外的研究进展;另外还从改善膜本身的抗污染能力,变化混合液的特性,优化膜分离的操作条件和膜清洗四个方面介绍了膜污染的防治方法。更多还原

【Abstract】 The scale and amount of MBR applied to wastewater treatment are expanding, however, membrane fouling has blocked the further application of MBR to wastewater treatment. The formation of membrane fouling and process are analysed through the characteristics of membrane, the properties of the mixed liquor, and the operational conditions of membrane. The research development of membrane fouling in China and abroad are thoroughly reviewed. Moreover, the controlling measures of membrane fouling are presented in four aspects: modifying membrane to improve the ability of fouling resistance, changing the properties of the mixed liquor, optimizing the operational conditions of membrane separation and cleaning the membrane.更多还原
