摘要
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 rainwater utilization engineering in Zhenjiang city as a case to study,the pollution situation and the quality characteristics of rainwater runoff were obtained by monitoring the rainwater samples from 8 typical rainfalls.The variation of rainwater,quality of rainwater and their main influencing factors were analyzed,and the correlation among various types of pollutants was studied.The results revealed that more serious pollution was in the beginning of stormwater,with organic pollutants and suspended solids as major pollutants of the runoff.Rainwater quality would meet the quality of landscape and urban water quality control targets if abandoning the initial rainwater.
