【摘要】 为研究青海省海晏县海北化工厂地下水Cr(Ⅵ)污染治理方案,在深入分析青海省海北化工厂一带环境水文地质条件、历年地下水及地表水环境Cr(Ⅵ)监测资料、地下水Cr(Ⅵ)点状污染源现状规模、污染羽空间展布特征以及地下水污染途径等的基础上,分析了海北化工厂地下水Cr(Ⅵ)污染地下水污染机理。基于此,从保护水环境的角度,经多方案比选,推荐可渗透反应墙(PRB)技术为修复治理海北化工厂Cr(Ⅵ)污染地下水的最佳方案。更多还原

【Abstract】 In order to study the control method for groundwater pollution by Cr(Ⅵ) in Haibei chemical plant of Haiyan County,Qinghai Province,this paper proposed the groundwater pollution mechanism by Cr(Ⅵ) in Haibei chemical plant on the detailed analysis of the basic geological and hydrological conditions,annual observing data of Cr(Ⅵ) contents of surface water and groundwater,pollution sources of Cr(Ⅵ),and pollution pathways,and the spatial distribution and developing trend of the pollution pathway.Moreover,from the view of environmental reserves,several methods were discussed to control and abate water pollution by Cr(Ⅵ),it is recommended that the PRB technology is the optimized planning for the study area.更多还原
