雨水中病原微生物的控制技术

Technologies for Pathogenic Microorganism Control in Rainwater

雨水已成为当今水环境污染的重要影响因素之一,同时它也是一种宝贵的可利用水资源,但是雨水中存在一定量不同种类的病原微生物,如不进行一定处理或处理方法不当,会对人体健康造成危害,迄今为止因雨水中病原微生物引发的环境问题及人类健康问题已有很多。当前对于雨水的污染控制研究往往局限于氮、磷、化学需氧量等常规指标,而对其中病原微生物去除的研究却很少涉及,专门针对雨水中病原微生物的控制技术则比较少。该文在介绍雨水中病原微生物的污染状况的基础上,阐述了美国最佳管理实践(BMPs)及过滤与消毒等技术在控制雨水中病原微生物方面的应用。

Nowadays, rainwater has been one of the most important factors in water environment pollution. Rainwater is also a kind of valuable and available water resource. However, it contains some different kinds of pathogenic microorganism, which can cause the risk of human health, if without removing or handling properly. So far, there have been a lot of environmental and healthy problems caused by the pathogenic microorganism in rainwater. The current study on controlling the polluted rainwater is limited to convention- al parameters such as nitrogen, phosphorous and chemical oxygen demand （COD）. Pathogenic microorganism has not been deeply concerned and few control technologies specifically against the pathogenic microorganism in rainwater has been developed yet. Based on the pollution situation of pathogenic microorganism in rainwater, some control technologies such as the Best Management Practices of America （BMPs）, filtration and disinfection were expounded.
