滏阳河邯郸段CODCr降解系数研究

降解系数的确定是水环境容量核算的关键因素。通过现场水团追踪实验,采用一维稳态水质模型进行参数率定;同时进行了室内模拟研究,运用最小二乘法进行回归计算,综合考虑2种方法测定结果,得到滏阳河邯郸段枯水期CODCr降解系数为0.152~0.270d-1;平水期CODCr降解系数为0.209~0.384d-1;丰水期CODCr降解系数为0.215~0.437d-1。

Research on CODCr degradation coefficient of the Fuyang River in Handan section

Degradation coefficient is a key factor in the process of environmental capacity. The CODCr degradation coefficient of the Fuyang River in Handan section was determined by tracking water masses and using one-dimensional water quality model. At the same time, through laboratory simulation and by using least square method regression analysis, considering two methods for the analysis results, the CODCr degradation coefficients at withered water period, normal river flow period and high-water period are 0.152~0.270 d^-1, 0.209~0.384 d^-1, 0.215~0.437 d^-1.
