摘　　要：以上海化学工业区某典型化工企业57场降雨径流在线监测数据为基础,模拟不同初期雨水收集深度情景下化工企业雨水排放口水质达标率与雨水系统运行费用的变化。分析结果显示,化工企业收集20 mm初期雨水后,预计污染降雨径流流量下降32%,雨水水质超标频率降低72%,企业雨水系统运行费用减少32%。因此,化工企业做好初期雨水管控,能够显著减少雨水系统运行费用,同时可以有效降低企业水环境污染风险。Changes in water quality compliance rate at rainwater outfall and the rainwater management cost in chemical industrial enterprises were simulated under different first flush collection depth scenarios,based on the monitoring data of the rainwater runoff from 57 rainfall-runoff events in a typical chemical industrial enterprise in Shanghai Chemical Industrial Park.The analysis revealed that after collecting an initial rainfall depth of 20 mm,the expected amount of polluted rainwater decreased by 32%,the frequency of the water quality non-compliance decreased by 72%,and the rainwater management cost decreased by 32%.Therefore,effective first flush control measures can significantly reduce the rainwater management cost and mitigate water pollution risks for chemical industrial enterprises.
