江西省重要江河湖泊水功能区纳污能力核定及分阶段限制排污总量控制方案研究

Research on the carrying capacity of water function areas and phased limitation of water pollution load control schemes for major rivers and lakes in Jiangxi province

本文以江西省178个重要江河湖泊水功能区为研究对象,根据流域水功能区概况、水质目标和水体自净能力分析水功能区水资源质量状况,建立水质数学模型,合理确定设计流量等相关参数,计算水功能区纳污能力,结合现状年污染物入河情况提出2015、2020和2030年水功能区限制排污总量控制方案,为江西省水资源保护与管理提供科学依据.

To study the carrying capacity of water function areas in Jiangxi province, 178 important rivers and lakes were selected as study areas. According to the underlying conditions, the water quality and the water self-purification ability in the water function area, the carrying capacity was calculated through establishing the mathematical model of water quality and setting the design flow and other related parameters reasonably. Then the program was proposed combined with the current conditions about sewage into rivers, which was used to control the amounts of total pollutants of water function areas in 2015, 2020 and 2030. It could provide valuable references for the protection and management of water resources in Jiangxi province.
