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，本文根據研究區受納水體的特點，建立了佛山市張槎鎮南北大涌的一維非穩態水質模型，相應地開發了基於fortranpowerstation平臺的水質模型計算程序，並在swmm模型模擬結果的基礎上，利用本文編制的水質模型程序計算了不同截流倍數時南北大涌codcr濃度的時空變化過程，分析了截流倍數對河涌水環境質量的影響。 -
