Design of embedded rainwater collection system in sponge city construction
摘要
Abstract
The city water resource system as a subsystem of the nature system makes good use of rainwater resource in the city to improve the regional environment. In this paper,an embedded rainwater collection system in the sponge city construction is put forward. According to the different collection methods,the roof rainwater collection,road rainwater collection and green area rainwater collection are summarized. The annual rainfall is calculated to collect the rainfall data,and the runoff coefficient is used to understand the ground catchment area,ground slope,road paving and building density distribution to preliminarily de-sign the rainwater sewer for the embedded rainwater collection system. The initial rainwater drainage control technology and cy-clone separation control technology are used to process the pollutants in the collected rainwater. The scouring rule and transporta-tion rule of rainwater runoff for pollutants are used to control the impurity and non-point source pollution in rainwater,and then the cyclone separator is adopted to separate the sediment which is difficult to separate from the rainwater. By means of the above steps,the comprehensive design of the city rainwater collection system is accomplished. The experimental results show that the embedded rainwater collection system can improve the utilization of rainwater resource.关键词
