摘　　要：根据长寿经济技术开发区水文地质条件,应用Visual Modflow软件建立研究区地下水水流和溶质运移数值模型,对表面处理园污水处理站污水处理池池底泄露后Cr^(6+)在地下水中的迁移趋势和环境影响进行预测评价。结果表明:Cr^(6+)向河流方向运移,10后运移距离为112 m,污染停止泄露后浓度由30 mg/L降至9 mg/L。虽然污染范围相对较小且无居民区及环境敏感点,但对地下水水质影响严重。针对化工园区企业数量较多、企业类型多样、废水污染物种类繁多且危害性大等特点,需加强园区地下水监管。According to the hydrogeological conditions of Changshou Economic and Technological Development Zone,the groundwater flow and solute transport models were established by the Visual Modflow software,which was used to conduct a numerical simulation that forecast the transport process and the environmental impacts of Cr6 ＋ in groundwater after sewage leakage happened in sewage treatment pond bottom of the surface treatment Park. The results show that the contamination plume of Cr6 ＋ transports towards the river,the distance of contamination transport is 112 m in 10 years,the concentration of Cr6 ＋ in groundwater from the 30 mg. L- 1 to 9 mg. L- 1 after pollution stopped leaking. Although the scope of pollution is relatively small,no residential and environmentally sensitive point in this scope,but a serious impact on groundwater quality.The companies of the Chemical Industrial Park are numerous and diverse,pollutants of wastewater are hazardous. Therefore,the Chemical Industrial Park need to strengthen supervision of groundwater.
