Second , based on the characteristic of the receiving water studied in this paper , develope a dynamic one - dimension water quality model for nanbei river in zhangcha town of foshan city , and develope a program of water quality model based fortran powerstation . and then , calculate the concentration of codcr in receiving water using the simulation results of swmm and analyze the effect on the environment of receiving water by intercepting ratio . at last , the construction investment and operational and administrative expenses of intercepting trunk sewer 、 pumping station and sewage farm is calculated and the relation between them is discussed
其次,本文根据研究区受纳水体的特点,建立了佛山市张槎镇南北大涌的一维非稳态水质模型,相应地开发了基于fortranpowerstation平台的水质模型计算程序,并在swmm模型模拟结果的基础上,利用本文编制的水质模型程序计算了不同截流倍数时南北大涌codcr浓度的时空变化过程,分析了截流倍数对河涌水环境质量的影响。
