摘要
简述了国内外再生水灌溉应用现状,详细介绍了再生水灌溉对浅层地下水污染的途径和机理,具体分析了再生水灌溉对浅层地下水水质的影响,系统介绍了再生水灌溉常用评估方法以及风险评估的发展趋势,并提出了降低城市污水处理厂尾水再生利用时对浅层地下水的污染风险的相关建议。
This paper introduced current applications of reclaimed water irrigation at home and abroad, focusing on routes and mechanisms of reclaimed water irrigation on the shallow groundwater pollution. The influence of reclaimed water irrigation on the shallow groundwater quality and potential pollutions has also been analyzed, with a detailed discussion of commonly used risk assessment and its developing trend. Finally, some suggestions are put forward to reduce the risk of the shallow groundwater pollution when the tailrace water is recycled from urban sewage treatment plants.
