生物滞留池净化雨水径流中氮磷的研究进展

Progress on purification of nitrogen and phosphorus in rainwater runoff by bioretention

生物滞留池作为雨水管理的技术措施之一,在雨水径流净化和调蓄方面具有较好的功效,因此受到研究者广泛关注。分析了传统生物滞留池对氮和磷的去除效果,并从填料组成、池体结构两个方面,对改良型生物滞留池的污染物去除效果进行了分析。基于目前改良型生物滞留池的研究现状,分析了这方面仍存在的问题及推动改良型生物滞留池技术应用的几个主要研究方向。

As one of the technical measures for rainwater management,bioretention has a good effect on the purification and storage of rainwater runoff,which has been widely concerned by researchers.The removal effects of traditional bioretention and improved bioretention on nitrogen and phosphorus were analyzed respectively in this paper.The improved bioretention was the traditional bioretention reformed with filler composition and bioretention structure.The existing problems and several main research directions for the application of improved bioretention have been analyzed and proposed.
