摘　　要：针对江苏省扬中市某黑臭河道污染情况,采用“控源截污+沉水植物+微孔曝气+仿生生物帘+生态浮床”组合工艺构建生物/生态系统进行综合治理。运行结果表明,出水透明度达到70 cm,ORP达到145 mV,DO达到5.1 mg/L,NH_(3)-N降至0.9 mg/L,COD降至20 mg/L,TP降至0.31 mg/L,达到GB 3838-2002中的Ⅴ类水标准,部分指标达到GB 3838-2002中的Ⅲ类水标准,消除了河道黑臭现象。运行费用约为0.01元/(m^(2)·d),运行费用较低。该项目可为同类城市黑臭河道水质净化提升提供经验参考。Aiming at the pollution of a black and odorous river in Yangzhong City,Jiangsu Province,the combined processes of source control sewage interception,submerged plants,microporous aeration,bionic biological curtain and ecological floating bed were used to build a biological/ecological system for comprehensive treatment.The operation results showed that the transparency of effluent reached 70 cm,ORP reached 145 mV,DO reached 5.1 mg/L,NH_(3)-N decreased to 0.9 mg/L,COD decreased to 20 mg/L,TP decreased to 0.31 mg/L,met the class V water standard of GB 3838-2002,and some indicators reached the class III water standard of GB 3838-2002,eliminating the black and odor phenomenon in the river.The operating cost was just about 0.01 yuan/(m^(2)·d).The project can provide experience reference for the water purification and improvement of black and odorous rivers in similar cities.
