入太湖河道水质达标研究——以无锡新区伯渎港为例

Water quality of inflow river channels of Taihu Lake: A case study on Bodugang River in Wuxi New District

利用河网区非稳态水量、水质数学模型及水文、水质、污染源同步观测资料,推求了河道糙率及水质降解系数。通过建立的河网模型计算了不同水质、水量及污染源条件下伯渎港河COD、氨氮水质浓度,对伯渎港河的水质达标性进行了研究,提出了使水质达标的工程措施。研究表明,边界水质条件对伯渎港水质达标影响很大,要根治水环境,必须从源头抓起,进行截污。

A non-steady state water quantity and water quality model for river networks and synchronous hydrology, water quality and pollution source monitoring data were used to determine the roughness and water quality degradation parameters of rivers. With the calculation of the concentrations of COD and ammonia nitrogen under different hydrological and pollution source conditions, water quality in the Bodugang River is analyzed and suitable pollution control measures are provided. It can be concluded that the boundary conditions of water quality have significant impact on the water quality of the Bodugang River. The method to improve the water environment is to cut down the pollution sources.
