摘要
再生水作为改善城市景观用水纳入河道,可其对地下水具有潜在的污染风险。通过构建区域地下水数值模型,应用质点追踪技术,计算出永定河补水区在河湖受水后地下水5 a运移1.47 km、20 a运移6.32 km,年均运移0.32 km。在数值模拟的基础上,依据地下水运移轨迹,结合区域水文地质条件,将研究区划分为核心监控区、二级监控区和控制监控区3个地下水监测分区,并提出各分区地下水监测井的布设原则及布设方式,实现地下水环境监测网络的优化。
Reclaimed water,which was used as replenished water to improve urban landscape,was drained into river,while it have potential pollution risk to groundwater because of its complex composition.A numerical simulation of a groundwater basin was established,combining with particle transportation technology,to calculate the groundwater of Yongding River moving 1 .47 km in 5 years and 6.32 km in 20 years,the average velocity is 0.32 km per year.Based on the particle transport model of groundwater numerical simulation,three monitoring districts were set:Core monitoring area,Second monitoring area and Control monitoring area,and presented the layout principle and the method of monitoring wells.
