摘要
通过对上海市雨水径流水质的监测,以及对其污染主要影响因素与污染程度的分析,掌握水质特性及其变化规律。通过雨水径流的混凝沉淀试验研究,确定了雨水混凝沉淀最适宜的混凝剂种类、最佳的混凝反应运行条件及最优的药剂投加量。在最佳混凝条件下,雨水径流浊度的去除率达99%。因此,混凝沉淀是雨水径流处理利用及污染控制最简便易行且有效的处理方法。
The rain runoff water quality in Shanghai was monitored and the main pollution factors influencing the water environment were investigated. Also the polluted degree, the water quality variation regulation were grasped. By experimental research of coagulation and sedimentation, series operating factors for rainwater treatment have been found out, for these the best operating parameters, best coagulants and best chemical dosage were included. Under best coagulation condition, removal of 99% for turbidity was obtained. So, it was believed that coagulation and sedimentation might be the simplest and very effective way to treat the rainwater runoff and for pollution control.
