纳污泡对周边地下水的影响研究

Influence of Sullage Blister on Surrounding Groundwater

通过对接纳石油化工废水的纳污泡进行土柱淋渗试验,获得废水经包气带进入地下水时的污染源强浓度和包气带的吸咐—释放量的特征值;采用模型预测分析纳污泡对周围地下水产生的影响。结果表明:纳污泡主要污染物对承压水基本没有影响,对潜水的影响范围局限于下游31.8 m以内,说明长期接纳石油化工污水的封闭泡沼会对浅层地下水造成一定程度的影响,但影响不大。

The concentration of pollution source entering underground water through aerated zone and the characteristic values for adsorption ＆ release of aerated zone were gained by leach test of earth pillar on petrochemical wastewater-holding water. It was indicated that main pollutants in water had no influence on artesian water and the influence scope to phreatic water was limited to 31.8 meters to the downstream by prediction and analysis using models, which means that blocked water holding petrochemical wastewater for long time had little influence on shallow groundwater.
