九星初雨调蓄池（星北路）设计

Design of Jiuxing Initial Rainwater Storage Tank (Xingbei Road)

摘要:

为了进一步控制区域面源污染、降低径流污染，在雨水排水系统建设初雨调蓄池，保证初期雨水不直排河道，实现区域内控污，提高区域水环境质量，对地区生态环境的提升启到了一定的积极作用。以九星初雨调蓄池（星北路）设计为例，通过对常用的重力流进水模式和水泵提升式进水模式进行比较分析，选取合适的进水模式。结合九星调蓄池（星北路）的选址位置及周边现状状排水管网，对下游受纳水体能力进行复核、运行模式等进行介绍，为类似工程的设计和运行管理提供技术参考。

Abstract:

In order to further control the regional non-point source pollution and reduce the runoff pollution, the construction of initial rainwater storage tank in the rainwater drainage system can ensure the initial rainwater not directly discharged into the river, which realizes the regional pollution control, improve the quality of the regional water environment and play a certain positive role in the improvement of the regional ecological environment. Taking the design of the Jiuxing Initial Rainwater Storage Tank (Xingbei Road) as an example, by comparing and analyzing the commonly used gravity flow inflow mode and pump lifting inflow mode, the appropriate inflow mode is selected. Combined with the location of Jiuxing Initial Rainwater Storage Tank (Xingbei Road) and the current drainage pipeline network around it, the capacity of downstream receiving water body should be rechecked and the operation mode is introduced, which provides the technical references for the design and operation management of similar projects.
