【摘要】 在分析国内外再生水回灌地下水研究现状及存在问题基础上,以高碑店污水处理厂再生水回灌试验场为例,采用三维荧光光谱等分析方法,分析再生水进入含水层后污染物运移变化规律及水质变化情况,分析再生水回灌浅层地下水的可行性,以及回灌地层对于再生水水质中有机物和无机物的净化和去除作用。同时通过使用发光细菌,评价了再生水回灌地下水的污染风险,对城市再生水的综合无害化利用提出建议。更多还原

【Abstract】 The groundwater recharging test field in Gaobeidian sewage treatment plant is taken as an exam-ple to analyze current research status and problems of reclaimed water recharging groundwater both at homeand abroad. For analysis on regular pattern of pollutant transport and the change of water quality after re-claimed water getting into the aquifer, three-dimensional excitation/emission matrix was employed to provethat recharging shallow groundwater with reclaimed water is feasible and that soil can purify and remove or-ganic matter and inorganic matter from reclaimed water. Meanwhile, with the help of light emitting bacte-ria, pollution risk of reclaimed water recharging shallow groundwater was evaluated. Sevaral suggestions areput forward for comprehensive utilization of urban reclaimed water.更多还原
