Abstract:Dongshan Town, Wuzhong District, Suzhou City is an important part of the ecological conservation area of Wuzhong District, Suzhou City. Most of the inland rivers in the township communicate with Taihu Lake, and the water quality of inland rivers has a certain impact on the water quality of Taihu Lake. Due to the mixed connection and misconnection of rainwater and sewage pipes in the surrounding plots, and the pollution of the surrounding agricultural non-point sources, the phenomenon of non-rainwater outflow from the river estuary is serious, causing serious pollution to the surrounding water environment. Therefore, this project is based on the planning objectives proposed in the "Planning of Suzhou Ecological Conservation Experimental Development Zone" and the "Notice of the Provincial Government on Printing and Distributing the Work Plan for Water Pollution Prevention and Control in Jiangsu Province", combined with the monitoring results of water quality. For rivers with poor quality and broken heads, various remediation measures such as source control and sewage interception, ecological dredging and ecological restoration are adopted to ensure that the water quality of the river is stable and meets the standard. In the later stage, combined with various methods such as farmland non-point source pollution control and non-rainfall outflow traceability investigation, the goal of Class III water quality in the eastern Taihu Lake area was finally achieved.
