    Vulnerability assessments of phreatic water in the Northern Shaanxi Energy and Chemical Base

    • 摘要: 随着陕北能源化工基地的建设和发展,地下水污染问题日益突出。为了预防基地地下水的污染,保护水资源,依据陕北能源化工基地地下水勘查、地下水污染调查、野外包气带原位污水垂直入渗、水平运移试验等基础资料,选取潜水位埋深(D)、降雨入渗补给量(R)、含水层岩性(A)、土壤类型(S)、地形坡度(T)、包气带介质(I)和含水层渗透系数(C)7个指标,运用DRASTIC指标叠加法,建立了陕北能源化工基地潜水易污性评价指标体系,对陕北能源化工基地潜水进行了易污性评。依据评价结果,将研究区潜水区划分为易污性高、中、低3个区,并针对3个区提出了相应的防污建议。

       

      Abstract: The pollution problem of phreatic water has become increasingly prominent with the construction and development of the Northern Shaanxi Energy and Chemical Base (NSECB). In order to prevent groundwater pollution and protect water resources, on the basis of the basic data of groundwater survey, groundwater pollution investigation and tests on in-situ sewage vertical infiltration and horizontal movement in the zone of aeration in the study area, the authors selected the depth of the phreatic water level (D), precipitation recharge (R), aquifer lithology (A), soil types (S), topographic slope (T), impact of zone of aeration (I) and permeability coefficient (hydraulic conductivity) of aquifer (C) as proxies and used the DRASTIC index system to establish the phreatic water vulnerability assessment system and evaluate the vulnerability of phreatic water in the study area. Finally, according to the evaluation results, the study area is divided into the high, middle and low vulnerable districts and corresponding measures and suggestions for pollution prevention in the three districts are put forward.
