活性污泥法废水处理技术的困境以及可能的出路

Troubles in Wastewater Treatment Technologies and Countermeasures

根据在欧洲工作的经验 ,总结了活性污泥法废水处理技术在当地面临的困境。指出 ,随着人们对环境质量要求的日益提高 ,现有废水处理技术已经不能完全满足水域和水源保护的要求 ,污水厂的作用应当包括拦截和去除有抗药性的病原体。作为储备有必要及时研究新型的废水处理技术 ,以应付将来在中国也会出现的类似局面。活性污泥法与微滤技术的结合可以提供新的出路。

Some issues encountered in modern wastewater treatment technologies based on act ivated sludges are summarized in this paper. It is pointed out that with the inc reasingly high requests on environmental quality from the society, the present technologies cannot fulfill the requirements of water area and water resource protection, and that the funct ion of wastewater treatment facilities should be extended by confining and killi ng resistant pathogens. It is necessary to develop new technologies as counterme asures to cope with the problems of this kind that may arise in China in the nea r future. The combination of activated sludges and microfiltration will open a n ew way in this respect.
