滹沱河典型场地土壤污染状况研究

Research of Typical Soil Contaminated Sites

对滹沱河流域某污灌场地垂直于河流布置了钻探剖面。通过土壤样品的采集与分析,研究了土壤不同污染物的污染概况。地表水测试结果显示水质为Ⅴ类水,地下水部分无机指标超标,多项有机指标检出。土壤中的重金属分布受土壤质地的影响较大,在土、砂交界处含量发生突变,在黏性土中含量相对沙层中较高。

Arranged a drill profile perpendicular to the river in Hutuohe sewage basin irrigation site. By collec- ting and analyzing soil samples, the soil contamination was studied. Test results show that the water quality of sur- face water is V water. Some inorganic indicators exceeded in groundwater with number of detectable organic indica- tors. The distribution of heavy metals in soil affected by soil texture, Mutations occur in the junction between soil and sand. The content in cohesive soils were relatively higher than sand layer.
