污废水生物脱氮除磷技术发展研究

[摘要]: 随着工业化和城镇化的快速发展,城市污废水越来越多,给城市污水处理厂的处理工作带来了较大的难度。我国城市污水处理厂主要是处理污水中的磷源污染物,脱氮率和处理效率均远远达不到标准。文章分析了生物脱氮除磷技术的工作原理,并针对污废水生物脱氮除磷的工艺类型和污废水生物脱氮除磷技术的发展趋势进行了研究。

Development of Biological Nitrogen and Phosphorus Removal Technology for Wastewater

Abstract: With the rapid development of industrialization and urbanization, more and more municipal wastewater has been produced, which makes the treatment of municipal wastewater treatment plants more difficult. Municipal sewage treatment plants in China mainly deal with phosphorus source pollutants in sewage, and the nitrogen removal rate and treatment efficiency are far below the standard. This paper analyses the working principle of biological nitrogen and phosphorus removal technology, and studies the technological types of biological nitrogen and phosphorus removal of wastewater and the development trend of biological nitrogen and phosphorus removal technology of wastewater.

Keywords: Biological nitrogen and phosphorus removal technology; Wastewater; Phosphorus removal effect; Sewage treatment

伴随着我国经济的飞速增长,我国水资源污染问题越来越严重,地球环境劣化及水体富营化问题,导致污水处理难度增加。为了改善污水处理问题,需要解决传统处理工艺中去除氮、磷效率差的问题,而且传统处理工艺还存在成本高的问题,因此污水处理厂需要加强对污废水生物脱氮除磷技术的研究,以期实现我国污废水处理的高效性、经济性、节能性,从而促进我国环境保护更进一步发展。
