感潮河流水环境容量计算——以太湖流域太浦河为例

Calculation of tidal river environmental capacity using Taipu River in Taihu Basin as an example

为了探讨感潮河流水环境容量计算方法,以太湖流域重要的感潮河流——太浦河为研究对象,在水量、水质模拟计算的基础上,建立了感潮河流水环境容量计算模型,核算了太浦河的水环境容量,并对核算结果的合理性进行了验证。结果表明,2003年型(P=88%)降雨条件下,太浦河COD水环境容量为14405 t/a,NH3-N水环境容量为1 007 t/a。

In order to probe the method of water environmental capacity calculation for a tidal river,using the Taipu River,a typical tide-influenced river in Taihu Basin,as an example,a non-constant model for calculating a tidal river s carrying capacity was developed based on calculations of water quantity and water quality.The model was used to calculate the environmental capacity of the Taipu River,and the rationality of the results from the calculations was validated.The results showed that,with a rainfall frequency of P = 88 % in 2003, the Taipu River＇ s environmental capacities of COD and NH4＋ -N were 14405 t/a and 1 007 t/a, respectively.
