生态城镇污水再生利用技术路线

The Technical Route of Wastewater Reuse in Eco-towns

生态城镇是人类、自然、社会三者高效和谐共生互惠的城镇发展模式。本文提出了A^2/O高效脱氮除磷预处理与人工生态湿地深度处理技术路线,这将有效地解决当前尾水回用存在的氮磷不易彻底除去及回用管网投资巨大这两大难题,对生态环境保护、可持续发展与循环经济理念推广具有十分重要的战略意义。

Eco-town is a model of urban development in which humans,nature,and society coexist in an efficient,harmonious,and mutually beneficial manner.This paper proposes the technical route of A^2/O high-efficiency nitrogen and phosphorus removal pretreatment and artificial ecological wetland advanced treatment,which will effectively solve the two major problems of the difficulty of removing nitrogen and phosphorus in the current tail water reuse and the huge investment in the reuse pipe network,and has very important strategic significance for the promotion of ecological environment protection,sustainable development and circular economy concepts.
