| 摘 要： | 分析了天津中心城区分流制雨水水质特性,探讨了混凝、沉淀、过滤常规物化处理对径流雨水中污染物的处理效果.试验结果表明：分流制雨水不适于直接排入景观河道,因其易引起水体的富营养化现象.混凝剂聚合氯化铝对有机物和浊度处理效果最好,最佳投药量为20～25,mg/L.多层滤料和单层滤料的过滤效果相比,前者对浊度、CODcr、总氮、总磷的去除率明显高于后者,且出水可达到城市杂用水水质标准.

| Abstract: | The quality characteristics of rain runoff water in the separate system in Tianjin metropolitan area are analyzed;the treatment effects of usual physico-chemical methods,such as coagulation,sedimentation and filtration,on the removal of organic contamination in rain runoff water are discussed.The results indicate that rain runoff water in the separate system is not advisable to drain into landscape water directly,because it is prone to produce eutrophication.PAC has the best removal effects for most polluta... |
