青岛大沽河水源地地下水水质的数值模型预测

大沽河是胶东半岛最大的河流,近几年随着城市发展,用水量增加,其水环境问题也日益突出,利用已有资料,结合本次水文地质及环境地质调查、野外弥散试验等工作成果,建立青岛市大沽河水源地地下水质数值模型并进行验证,模拟预测地下水污染并分析治理对策,通过预测,在进入地下水的污染物质浓度每年平均递减3%的情况下,今后10年内,大沽河水源地地下水质大部分地段有变好的趋势,下游李哥庄镇附近有变差的趋势。

Application of Numerical Modeling to Prediction of Water Quality in Dagu River Groundwater Source Area, Qingdao

Dagu River is the longest river in the Jiaodong Peninsula. With the city development and water utilization increase, water environment in the Dagu River source area is more and more important. In this paper, a groundwater quality numerical model is built up to predict the groundwater pollution in the Dagu River source area based on hydrogeological and environmental geological investigations and field tests. Using the numerical models, the groundwater pollutant concentration will decrease at a rate of 3% annually in the decade to come in most parts of the source areas, but pollution trend near Ligezhuang Town, which is the lower reach of the Dagu River, will aggravate.
