Rainwater runoff outfall control method and technology based on water quality target of urban river and lake
In order to solve a series of problems,such as the absence of close connection be-tween urban rainwater runoff management and urban river and lake environment,the lack of basis for the setting of rainwater runoff management objectives,the pollution of water bodies in rainy season,a complete set of technical system for rainwater runoff control was constructed,and the corresponding process selection of rainwater runoff control schemes in the technical system was put forward based on the different stages of rainy and non-rainy periods.It overcame the problems of poor treatment effect of traditional rapid purification technology and unstable operation and mainte-nance of high-efficiency treatment technology in rain and non-rain periods,and provided scientific support for realizing rapid purification of urban rainwater runoff and high-quality and long-term op-eration of urban rivers and lakes.
