水环境治理项目中初雨箱涵的优化分析

Analysis of Optimization of Primary Rainwater Box in Water Environment Treatment

随着城市建成区雨水径流污染对受纳水体水质影响的日益加重,初雨调蓄作为一种行之有效的控源截污措施在国内得到广泛应用。结合广东省某水环境治理项目,介绍了初雨箱涵设计及运行模式等要点,并通过对相关控制系统进行优化设计,使其能充分发挥工程效益。通过预测初雨箱涵建成后的运行效果,表明初雨箱涵建设能够显著削减入河的初雨量,对改善河涌水质起到关键作用。

With the increasing impact of rainwater runoff pollution on water quality in urban built-up areas, primary rainwater regulation and storage has been widely used as an effective measure in China. Based on a water environment treatment project in Guangdong Province, key points of the design and operation mode of the primary rainwater box culvert are introduced. The relevant control system is optimized to full play engineering benefits. By predicting the operation effect of the completed primary rainwater box culvert, the construction of the primary rainwater box culvert can significantly reduce the amount of rainwater entering the river and play a key role in improving the water quality of the river.
