摘　　要：介绍了现场试验河道以“缓流沉淀+生态河床+悬浮生态岛+生态滤坝”为主要工艺的河道水体原位生态净化工程,重点描述了工程的主要构筑物、技术参数以及功能作用,工程建成后,对微污染河水的实际净化效果进行研究。实践证明,采取河道水体原位生态净化措施对水质具有较好的净化效果,对COD、NH3-N、TN的平均去除率分别为25. 26%、32. 19%和17. 72%,改善了水体溶解氧环境,系统下游出水水质基本稳定能达到GB 3838-2002《地表水环境质量标准》Ⅴ类水质标准。This paper introduced the in-situ ecological purification project of river water body with “slow precipitation+ecological riverbed+suspended ecological island+ecological filter dam” as the main process in the field test;the main structure, technical parameters and function of the project were described in details;and the actual purification effect on the micro-polluted river water was studied after the completion of project. Results showed that: in-situ ecological purification measures of river water had better purification effect on water quality, with average removal rates of COD, NH 3-N and TN respectively up to 25.26%, 32.19%,and 17.72%;dissolved oxygen environment in water body was improved, and the water quality of the downstream outlet of the system was basically stable and could reach the level Ⅴ of Surface Water Envionmental Quality Standard (GB 3838-2002).
