摘要
随着九江市的快速发展以及水资源开发利用程度进一步提高,城市水环境污染问题也日益突出,九江中心城区城市水环境状况的空间特征与城市人口和产业分布基本一致,区域水环境治理需求强烈。文中通过摸清九江市中心城区地表水环境状况,分析各区块主要污染源及污染负荷。结果显示:九江中心城区各区块中八里湖、赛城湖的生活污染源、城市面源、农业面源和底泥内源都占有相当比例;琵琶湖、白水湖、两湖和两河主要以生活污染为主;城西港区、赤湖工业园和芳兰主要以城市面源污染为主。通过实施城镇生活污水、城市面源、工业污染和河湖底泥内源等污染源全面治理工程,控制大部分城镇生活污染源进入区域内水体,同时,通过多种面源污染控制及强化净化措施,形成污染物削减体系,对改善九江中心城区河湖水质和保护生态环境具有重要意义。
With the rapid development of Jiujiang City and the further improvement of the development and utilization of water resources,the problem of urban water environmental pollution has become increasingly prominent.Spatial characteristics of the water environment in the central city of Jiujiang are basically the same as urban population and industrial distribution,and there is a strong demand for regional water environment governance.In this paper,the main pollution sources and pollution load of each block were analyzed by making clear the surface water environment of Jiujiang City.Results showed Bali Lake and Saicheng Lake were polluted by domestic pollution sources,urban non-point sources,agricultural non-point sources and internal sediment sources.Bipa Lake,Baishui Lake,Lianghu and Lianghe were mainly polluted by domestic pollution.Chengxi Port District,Chihu Industrial Park and Fanglan were mainly polluted by urban non-point source pollution.Through the implementation of comprehensive treatment projects,controlling the entry of most urban domestic pollution sources into the water,a variety of non-point source pollution control measures to form a pollutant reduction system,which will help protect Yangtze River.
