摘要
基于雨水出流污染的复杂性、随机性,为更好指导污染雨水的原位净化研究,以九江市老鹳塘污水系统为工程实例,开展雨水出流污染数学模型模拟研究。利用InfoWorks ICM模型,分析沿湖截流调蓄与原位净化处理设施工程改造对雨水出流污染的削减效果。研究模拟结果表明,待工程顺利完工实施后,年入湖溢流水量和年径流污染CODCr入湖污染负荷均预计有显著的削减效果:排口年溢流频率减低80%,溢流水量削减率为78.5%,径流污染CODCr年负荷削减率为87.6%。
Based on the complexity&randomness of rainwater outflow pollution,in order to better guide the research on in-situ purification of polluted rainwater,a mathematical model simulation study of rainwater outflow pollution is conducted using the Laoguantang sewage system in Jiujiang as an engineering example.Using the InfoWorks ICM model,the reduction effect of interception&storage along the lake and the renovation of in-situ purification treatment facilities on rainwater outflow pollution is analyzed.The simulation results show that after the successful completion of the project,the annual inflow of overflow water into the lake and the annual COD_(Cr)load of runoff pollution into the lake are expected to have significant reduction effects:the annual overflow frequency of the discharge outlet is decreased by 80%,the reduction rate of overflow water is 78.5%,and the annual reduction rate of runoff pollution COD_(Cr)load is 87.6%.
