| 摘 要： | 试验研究了青岛市黄岛区降雨历时内雨水水质的动态变化和采用沉淀、混凝和过滤等物化处理的效果.结果表明:初期径流(前30min)污染较重,应弃流;自然沉淀和过滤对COD的最大去除率为32.35%和52.65%,水质达到杂用水要求;混凝处理COD去除率仅30%左右,不宜采用.确定了以初期弃流-沉淀-过滤为主的适合屋顶、路面和绿地雨水收集、处理和利用的技术路线,并进行了效益分析.

| Abstract: | The dynamic change of rainwater quality in a raining time and the effect of its physicochemical treatments,such as natural sedimentation,flocculation and filtration were researched.The results indicated that the initial runoff in first 30 min was polluted seriously and should be discarded;the maximum removal rates of COD by natural sedimentation and filtration were 32.35% and 52.65% respectively,and the water quality satisfied the requirement for multi-purpose;the removal rates of COD by flocculation was ju... |
