| 摘 要： | 生物滞留设施是城市雨水管理和海绵城市建设的典型技术措施之一，其对城市雨水径流中氮、磷污染物的净化机理和控制效果受到研究人员广泛关注。通过系统梳理生物滞留设施对不同形态氮、磷的净化机理研究进展，分析了传统生物滞留设施对雨水径流中氮、磷污染物的控制效果；进而从设施填料组合与配比、淹没出流区设置、碳源添加和填料填装方式4个方面，系统分析了生物滞留设施对雨水径流中氮、磷污染物净化效果的提升方式和效果。基于目前研究的不足和海绵城市建设中实际工程技术需求，从生物滞留设施对雨水径流氮、磷污染物控制方面展望了未来重点研究方向。

| Abstract: | Bioretention is one of the typical technical measures for urban stormwater management and sponge city construction. The nitrogen and phosphorus purification mechanism and pollution control effect of bioretention for urban stormwater runoff had been thoroughly investigated. The purification mechanism of different forms of nitrogen and phosphorus was systematically summarized, and the control effect of traditional bioretention on nitrogen and phosphorus in stormwater runoff was analyzed. The improvement of bioretention on the nitrogen and phosphorus purification effect for stormwater runoff was systematically analyzed from four aspects, media types and composition, submerged zone setting, carbon source addition, and media packing arrangement. Based on the current research and the actual engineering demand in the construction of sponge city, the future research directions of nitrogen and phosphorus control were forecasted. |
