| 摘 要： | 针对河流受漏截污水和面源污染物输入的普遍现状,结合人工湿地技术和生物滤池、人工快渗技术,构建出一种具有净化河道水质的生态滤槽。生态滤槽对污染河水的动态净化效果表明,COD、氨氮、总氮、总磷的去除率随水力负荷及进水流量的增大而降低,在水力负荷为0.5 m~3/(m~2·d)时去除率最高,净化效果最好。污染河水经生态滤槽处理后,COD、NH_4~+-N、TN、TP的平均去除率分别达77.20%、63.29%、57.87%、75.64%。减少生态滤槽数量,发现该生物滤槽出水稳定,抗负荷冲击能力强。

| Abstract: | In accordance with river pollution by sewage interception and non-point sources injection,ecological filter tank sys-tem was constructed for river purification by combining constructed-wetland purification,biological filter and constructed rapid infiltration technology. The results of dynamic purification efficiency showed that the average removal efficiencies of COD, NH4+-N,TN,TP were decreased with the increase of hydraulic loading rates. When the hydraulic loading rate was 0.5 m3/(m2?d), the ecological filter tank exhibited the best purification capacity,of which the average removal efficiencies reached 77.20%, 63.29%,57.87%,75.64%,respectively. Also, the ecological filter tank exhibited perfect stability and good load to impact by re-ducing the quantity of tank. |
