用于控制径流颗粒物的雨水口截污装置结构优化及其性能
Structural optimization and performance of a storm drain inlet interception device for controlling runoff suspended solids
摘要
Abstract
To design a storm drain inlet structure that meets drainage flow requirements and effectively controls suspended solids(SS),numerical simulation methods were used to optimize the structure of the interception device.The geotextile material,pre-selected through experiments,was incorporated into the optimized device,and the dynamic SS interception performance and maintenance cycle of the modified storm drain inlet were investigated through physical model experiments.The results showed that when the overflow opening dimensions of the central overflow-type interception device were 100 mm×220 mm,and the bottom of the device was aligned with the centerline of the connecting pipe,the interception space and area were maximized,making it the optimal structure.This configuration met the drainage flow requirement of 20 L·s−1 for storm drain inlets with connecting pipe diameters≥200 mm and pipe-top-to-ground distances≥300 mm.By deploying a filter bag made of double-layer 250 g·m−2 geotextile within the interception device,the single-event removal rate of SS exceeded 90%.Based on monitoring data from the model experiments,a formula for quantifying the controllable rainfall volume of the interception device was derived.Combined with local long-term rainfall statistics,this formula can be used to predict the maintenance cycle of the system.关键词
