雨水就地处置方式的环境风险评价

雨水的就地处置正在成为一种新的处理雨水的方法，但是由于雨水径流水质的不稳定性，回灌可能会对环境产生不利的影响。因此在实施雨水回灌前需进行环境风险评价。通过对上海市雨水径流中常见污染物质含量分析（包括重金属，微生物，阴阳离子以及常规水质指标4个方面），对各种监测和实验数据进行详细分析，得出在严格控制回灌区域，保证回灌雨水水质的前提下，雨水回灌不会对环境带来不利影响的结论。

Environmental Risk Assessment for Stormwater Disposal in Situ

Stormwater disposal in situ has gradually become a newly alternative method, it will bring some environmental risk due to fluctuate of stormwater quality. So the environmental risk assessment should be done before construction. Based on some monitoring and experimental data analysis, including heavy metal, microorganism, anion, cation and routine water quality indexes, the environmental, risk of stormwater recharge to ground was assessed. The result showed that stormwater recharge to ground may not have bad influence on environment under strict control of stormwater quality and recharging location.
