温泉县城西地下水水源地可行性评价

Feasibility evaluation of west groundwater source in Wenquan County

温泉县城西地下水水源地位于新疆博州温泉县县城以西2 km处,为提高温泉县供水保障能力,在对区域水文地质详勘的基础上,结合水源地地下水的补、径、排条件,采用地下水平衡法对水源地内的水文地质条件、富水性特征、地下水资源量和供水可行性进行评价。结果表明:温泉县城西水源地内地下水资源量为1059×104 m^3/a,可开采系数取值0.2,对应地下水资源可开采量为212×104 m^3/a;拟建水源地计划年开采规模123×104m^3/a,占水源地地下水可开采量的58%;水质符合生活饮用水卫生标准,开采地下水对区域地下水位影响较小,对生态环境影响甚微,水源地供水可行性完全符合要求,建成后能够有效保证温泉县的用水需求。

The hot springs county west of groundwater reservoirs in Xinjiang Bo city 2 km west of hot springs county,the county to improve the ability to hot springs county water supply security,on the basis of the detailed the regional hydrogeology can be,in combination with water source,runoff discharge conditions of groundwater,the groundwater balance method is adopted within the water source on hydrogeology characteristics of the groundwater hydrogeological conditions and water resources feasibility evaluation results show that the hot springs county west water groundwater resource of 1059×104 m^3/a,the mineable coefficient value of 0.2,corresponding to the groundwater resource can be mined for 212×104 m^3/a,The annual exploitation scale of the proposed water source area is 123×104 m^3/a,accounting for 58%of the recoverable groundwater of the water source area.The water quality is in line with the sanitary standards for domestic and drinking water.The exploitation of groundwater has little impact on the regional groundwater table and little impact on the ecological environment.The water supply feasibility of the water source meets the requirements completely,which can effectively guarantee the water demand of Wenquan County after completion.
