大沙河焦作段水环境容量与容量总量控制研究

利用一维水质模型计算了大沙河焦作段的水环境容量,并在此基础上确定了其容量总量控制方案.研究结果表明,大沙河焦作段CODCr和NH3-N的水环境容量分别为1 213.05 t/a和60.22 t/a,远远小于CODCr和NH3-N的现状入河量3 852.64 t/a和461.3 t/a;为实现大沙河焦作段水环境目标,其CODCr的总控制量和总削减量分别应为978.59 t/a和2 874.05 t/a,NH3-N的总控制量和总削减量分别应为48.86 t/a和412.44 t/a.该研究可为大沙河焦作段水环境保护和管理提供基础资料和科学依据.

Study of Water Environmental Capacity and Total Content Control of Dashahe River of Jiaozuo Section

The water environmental capacity(WEC) of Dashahe River of Jiaozuo section was calculated by using one-dimensional water quality model and the scheme of total content control of pollutants was determined.The results showed that water environmental capacities of CODCr and NH3-N were 1 213.05 t/a and 60.22 t/a respectively,far less than the amount of CODCr and NH3-N discharged into the river,which were 3 852.64 t/a and 461.3 t/a respectively.In order to attain the water environmental quality objective of Dashahe River of Jiaozuo section,the quantities of total control and total reduction of CODCr should be 978.59 t/a and 2 874.05 t/a respectively,and the total amount of control and reduction of NH3-N should be 48.86 t/a and 412.44 t/a.The research would provide the basic data and a scientific basis for water environmental protection and management of Dashahe Rive of Jiaozuo section.
