摘　　要：[目的]研究生物砂滤池在中水回用中的应用。[方法]以某生态居民小区污水处理系统的出水为水源,分析了不同条件下生物砂滤池对TSS、COD_(Cr)、BOD_5、TN、NH_4^+-N、TP去除效果及规律。[结果]该生物砂滤池对于各种污染物都有明显的去除效果,尤其是对TN和NH+4-N有很高的去除率,处理后中水水质完全能够满足该生态小区杂用水和景观环境用水的需求。[结论]该研究为中水回用提供了理论依据。[ Objective ] The study aims to discuss the application of biological sand filter in water reuse. [ Method ] The removal effects and rules of TSS, CODcr, BOD5, TN, NH4 ＋-N and TP by the biological sand filter were analyzed using the effluent from the sewage disposal system in an ecological residential area as source water. [ Result] Tile removal efficiency of every pollutant by the biological sand filter is apparent, especially TN and NH4＊ -N, and the treated water can be used as miscellaneous water and scenic environment water of the ecological residential area. [ Con- clusion] The research can provide theoretical foundation for water reuse.
