英文摘要： The hydraulic and water quality variation process of rainwater runoff is studied deeply. According to different ground conditions, the erosion and transport law of pollutants in rainfall runoff is investigated. Then the city rainfall runoff model is established, and the parameters of accumulation and erosion process are optimized by sensitivity analysis. On the basis of equivalent simplification and compensation in the distribution network, the gradual and unsteady flow hydraulic model is developed using the kinematic wave and dynamic wave method, combined with the pollutants accumulation and erosion model of rainwater runoff. Besides the water quality change calculation model of main pollutants is established under the condition that the pollutants attenuation is simplified. On this basis, the characteristics of water quantity and quality change in pipe downstream outlet and intercepting well are analyzed on different rainfall intensity and recurrence period conditions. The water quantity and quality change law and pollution duration of initial rainwater are researched and the actual measurement and calibration are done. And then the relationship between hydraulic and water quality characteristics of initial rainwater and the design of pipe diameter, pipe, slope, etc is explored. The pollution control and drainage effect of initial rainwater interception and storage are analyzed.In the economy, runoff pollution control and network transmission capacity as the goal, a multi-objective optimization model of storm-water system is developed. The optimal construction of storm-water system is solved and the subject is redeveloped by the multi-goal intelligent evolutionary algorithm.
