针对重污染村镇河道——常州武进南宅河现状,采用底质改性、微纳米气泡复氧系统、微气泡复氧造流器系统、高效净水膜、浮岛式湿地与底栖动物控养等组合式生态修复工艺技术进行治理.工程运行结果表明,原河道的水质得到明显的改善,河水水质由治理前有劣Ⅴ类达到了治理后Ⅳ～Ⅴ类(《地表水环境质量标准(GB3838-2002)》),氮磷流失得到有效控制,为苏南地区乃至我国南方黑臭河道的治理提供了一种借鉴,工程示范与推广意义重大.%Based on the present situation of Nanzhai River in Wujin which is the heavily polluted,we govern it with combined ecological repairment technologies which include substrated modification technology,micro-nano bubble reoxygenation system,micro-bubbles reoxygenation converter system,efficient water purification membrane technology,wetland of floating island type technology and the benthic animal control raising technology.Operation results show that the river water,Which was worse than Grade Ⅴ,is obviously improved,and reaches Grade Ⅳ-Ⅴ (Quality Standard of Environmental for Surface Water (GB 3838-2002)).Nitrogen and phosphorus losses are under effective control.It provides a reference for river treatment of the Sunan region as well as black and stink rivers in southern China,the significance of engineering demonstration and promotion is outstanding.
