摘　　要：为了研究填料生物滤池对尾水氮磷净化效果的影响,构建了由3种填料(A1为高效膨润土+碎秸秆、A2为高效膨润土+木头沫、A3为高效膨润土+碎秸秆、木头沫混合物)组成的生物滤池,并对不同生物滤池的实际过滤效果进行分析。实际应用表明:A1状态下出水口处的COD含量最高、总氮去除率最高,A2状态下总磷去除率最高,为选择合适的生物滤池提供了参考。In order to study the effect of packed biofilters on the purification of nitrogen and phosphorus in tailwater,a biofilter composed of three types of fillers(A1 is high-efficiency bentonite+crushed straw,A2 is high-efficiency bentonite+wood foam,A3 is a mixture of high-efficiency bentonite+crushed straw and wood foam)was constructed,and the actual filtration effects of different biofilters were analyzed.Practical applications have shown that the COD content and total nitrogen removal rate are highest at the outlet in state A1,and the total phosphorus removal rate is highest in state A2,providing a reference for selecting suitable biofilters.
