| 摘 要： | 为了对再生水灌区调蓄工程选址提供依据，该文通过建立5个不同深度监测井研究了再生水灌区调蓄工程对地下水盐分的影响，再生水经包气带入渗后渗滤液氯离子、全盐、总硬度含量有所增加，12 m包气带厚度对总氮、总磷去除率达到97.3%和99.0%以上，但是渗滤液中全盐、总氮、氮磷、总硬度等含量指标接近地下水背景值，未发现再生水调蓄工程蓄水导致地下水水质发生明显变化，说明研究区域再生水渗滤进入地下水对盐分的影响与其他补给水源的影响效果无显著差异。再生水灌区调蓄工程应建设在具有包气带岩性粗细相间、防污性能较好的区域。

| Abstract: | The research of irrigation regulation and storage engineering on groundwater salinity was investigated in reclaimed water irrigation district (RWID) of Beijing for site selection. Five research wells with different depths around regulation and storage engineering were drilled to monitor water quality changes. Chloride ion of leachate, total nitrogen, total phosphors, hardness of water samples increased, and removal rate of total nitrogen, total phosphorus of water samples decreased by 97.3% and 99.0%, respectively in 12-meter vadose zone after infiltration, and the measured parameters were close to groundwater background values. Measured results indicated that groundwater was not polluted by reclaimed water infiltration, and there was no significant difference between the effect of reclaimed water and other water resources infiltration on groundwater. The vadose comprising of loam, sand and clay can prevent groundwater pollution for site selection of regulation and storage engineering in RWID. |
