膜技术对污水中病原微生物去除的研究进展

Progress in the removal of pathogenic microorganisms from wastewater by membrane technology

从公共卫生安全角度出发,分析了污水处理过程中可能存在的卫生学安全问题。综述了膜分离方法对细菌与病毒的去除机理,以及对病原微生物的去除效果,并对膜分离过程中存在的问题进行了初步分析,提出了在污水消毒方面应该注意和需要进一步研究解决的问题。

Aiming at public health and security, the possible problems concerned are analysed. The removal me- chanism of bacteria and viruses and other microorganisms by membrane separation is summarized. The removal rate of pathogenic microorganisms and the problems existed during membrane separation are analysed, too. The problems on wastewater disinfection to which attention needs to be paid are pointed out. Further studies about this are proposed.
