厂村融合型小流域污染控制关键技术及工程示范

Key Technologies and Project Demonstration of Industrial and Agricultural Integrating Pollution Control in a Small Watershed

结合武进港流域厂村融合型污染特征和成因,以东洋岸河小流域为治理对象,通过源解析划分污染控制单元,确定污染负荷空间分布规律,开展以分散式污水截流与尾水处理技术、农田面源污染控制技术、滨岸植被缓冲带、底泥生态清淤和智慧管理及监控等关键技术的开发和工程应用。该技术体系在东洋岸河流域治理中取得了显著的环境和社会效益,河道水质、生态环境、居民幸福感得到明显提升,为太湖流域厂村融合型小流域污染治理,建设城镇幸福河湖提供关键技术和示范。

Based on the characteristics and causes of the industrial and agricultural integrating pollution in Wujingang watershed,the Dongyang’an River watershed was taken as the object,and the pollution control units are divided to determine the spatial distribution of pollution loads by source analysis.The key technologies such as decentralized sewage interception,tail water treatment technology,farmland non-point source pollution control technology,coastal vegetation buffer zone,ecological sediment dredging and smart management and monitoring have been carried out.This technical system has achieved significant environmental and social benefits in the control of Dongyang’an River watershed.The river water quality,the ecological environment,and the resident’s happiness have been significantly improved.It can provide key technologies and demonstrations for the pollution control of small watersheds which integrate industrial and agricultural pollution in the Taihu Lake watershed to realize better rivers and lakes.
