城市污水处理技术的应用，不能提高污染物的去除效率，由于其特点是封闭和静态条件下的湖泊水。本研究选用天然沸石和煤矸石作为生态滤池的填料。通过静态和动态实验研究了该方法的修复效果。试验结果表明，静态和动态条件下氨氮（NH 4 +-N）的去除率均达到85%，动态条件下循环周期为1 h时，氨氮的去除率达到97%.亚硝酸盐氮（NO2−-N）的最大去除率达到98%，总氮（TN）的最大去除率为84%。出水TP浓度为0.079mg/L。出水回用能有效提高系统对氮、磷的去除率。溶解氧（DO）浓度可以保持较高的水循环。过滤器可有效地将pH值调节至健康水的标准水平。
Urban wastewater treatment techniques could not be applied to improve the pollutant removal efficiency, due to its characteristics of closed and quiescent conditions of the static lake water. In this study, natural zeolite and coal cinder were chosen as filler compounds of the ecological filter. Static and dynamic experiments were carried out to study the remediation efficiency. Experimental data show that removal efficiency of ammonia nitrogen (NH4+-N) reaches 85% in both static and dynamic patterns and its removal efficiency reaches 97% when the recycling period is 1 h in dynamic condition. The maximum removal efficiency of nitrite nitrogen (NO2−-N) reached 98%, and the removal efficiency of total nitrogen (TN) is a maximum of 84%. The final effluent concentration of total phosphorus (TP) is 0.079 mg/L. Effluent recycling could improve the nutrient (N, P) removal efficiently. Dissolved oxygen (DO) concentration could remain high with the water cycling. The filter works efficiently on regulating pH to the standard level of healthy water.
