以镇江市雨水利用示范工程为研究对象,通过对8场典型降雨雨水取样检测,得出了示范点雨水径流的污染状况和水质特性,分析各种雨水水质变化规律、雨水质量及其主要影响因素,研究各类污染物之间的相关性。结果表明:降雨初期径流污染严重,主要是有机污染物和悬浮物固体污染,雨水中的悬浮物与有机污染物浓度有一定的相关性;在弃去初期雨水后,水质基本满足景观环境再生水水质和城市杂用水水质的控制指标。
Taking the demonstration project of rainwater utilization in Zhenjiang City as the research object, the pollution status and water quality characteristics of the runoff at the demonstration sites were obtained through sampling and sampling of eight typical rainfall rainwater samples. The variation rules of rainwater quality, the quality of rainwater and its main influencing factors , To study the correlation between various types of pollutants. The results showed that the runoff pollution was serious in the early rainfall, mainly due to the solid pollution of organic pollutants and suspended solids. The suspended solids in the rainwater had some correlation with the concentration of organic pollutants. After the initial rainwater was abandoned, the water quality basically met the quality of reclaimed water And urban miscellaneous water quality control indicators.
