九洲江广东段水环境容量研究

在充分获取调研资料和实测数据的基础上 ,对九洲江广东段进行了功能区划分 ,并通过计算 ,得出各功能区的水环境容量 ,指出九洲江广东段各功能区现状纳污量基本上没有超过各自的水环境容量 ,但在确定原有排污口适宜排污量及削减方案时 ,不仅要考虑其所在河段的水环境容量值 ,还应考虑其水质预测结果。

Study on water environmental capacity for Guangdong section of Jiuzhoujiang River

The Guangdong section of the Jiuzhoujiang River was divided into several functional regions based on the data from sufficient investigation, and the water environmental capacity of each region was calculated. It is shown that the quantity of pollutants received by each region at present does not exceed their environmental capacity. However, in the determination of a suitable quantity of pollutant discharge from original outlets and the scheme for its reduction, both the water environmental capacity and the predicted water quality of corresponding sections should be taken into account.
