摘　　要：以常州市新桥镇藻港河西支为治理对象,遴选深层微孔层流曝气、微生物强化降解、生态浮岛等技术进行集成,对该黑臭河道进行治理与生态修复。第三方机构水质检测结果表明:该工程经过5个月的调试运行,河道水质状况明显改善,总磷、氨氮和COD的去除率分别达到84. 4%、98. 6%和65. 3%,治理后达到地表水Ⅳ类水质标准。工程实践证明,该集成技术能够有效去除黑臭水体中的有机物、氨氮、总磷等污染物,增加水体透明度和溶解氧。通过建立长效管护机制,可从根本上恢复河流生态系统,进而改善和维护水质。An integrated system of bottom laminar flow aeration, biological enhanced degradation, and ecological floating islands was used to treat the west branch of Zaogang River in Xinqiao Town, Changzhou. The testing results by the third party showed that the water quality in the river was significantly improved after five-month treatment. The average removal rates of TP, NH4＋ - N, and COD have reached 84.4%, 98.6%, and 65.3% respectively. The water quality was better than level IV in Environmental Quality Standards for Surface Water （GB 3838 -2002 ）. Practice has proved that this integrated system could effectively remove pollutants such as TP, NH4＋ -N and COD in the black-odorous river, increase water transparency and DO. Through the establishment of long-term protection plan, it could fundamentally restore river ecosystems and improve the water quality.
