摘　　要：近年来,水资源枯竭,水源污染越演愈烈,城市污水厂的处理负荷加重。雨水成为很好的中水备用水源,如果通过生物滞留设施对城市中的雨水进行收集利用,可以很好的缓解城市水源紧张和水质恶化问题。为有效提高生物滞留设施去除径流雨水中氮、磷等污染物的效果,分析对比了生物滞留池中传统填料和新型填料的异同,以萍乡市海绵城市建设中使用的新型填料和万哲希等使用的发酵木屑为例,提出了现存填料的不足和改进方向。In recent years,the exhaustion of water resources,water pollution is more and more intense,urban sewage plant treatment load increased.Rainwater becomes a good standby water source.If rainwater in cities is collected and utilized through biological detention facilities,water shortage and water quality deterioration in cities can be well alleviated.In order to effectively improve the removal efficiency of nitrogen,phosphorus and other pollutants from runoff and rainwater,the similarities and differences between traditional and new fillers in biological retention ponds were analyzed and compared.Taking the new type filler and the fermentative sawdust used in pingxiang sponge city construction as examples,the deficiency of the existing filler and the improvement direction are putforward.
