新疆霍城县地区地下水质量评价

[目的]评价新疆霍城县地下水质量。[方法]利用2014年新疆伊犁河谷地下水资源调查与评价工作所取得的水质数据,采用单因子评价方法对伊犁地区54组潜水、29组承压水进行质量评价。[结果]潜水中Ⅱ、Ⅲ、Ⅵ、Ⅴ类所占比例分别为50.00%、37.04%、7.41%、5.55%,承压水中Ⅱ、Ⅲ、Ⅵ、Ⅴ类所占比例分别为51.73%、41.37%、3.45%、3.45%,地下水水质普遍较好。造成地下水为Ⅵ、Ⅴ类的主要水化学组分是氨氮、SO_4~(2-)、总硬度(以CaCO_3计)及溶解性总固体(TDS)。[结论]霍城县地区地下水质普遍较好,适宜饮用。

Quality Assessment and Analysis of Groundwater in Huocheng Area of Xinjiang

Objective] The aim was to evaluate underground water quality in Huocheng County, Xinjiang.[Method] Based on the data ob-tained from groundwater resources investigation and evaluation of water quality in Yili River Valley of Xinjiang in 2014, using the single factor e-valuation method, quality of 59 groups of unconfined and 16 groups confined water were evaluated.[ Result] The results showed that proportion of unconfined waterⅡ,Ⅲ,Ⅵ,Ⅴtype respectively are 50.00%, 37.04%, 7.41% and 5.55%.The proportion of confined waterⅡ,Ⅲ,Ⅵ,Ⅴtype respectively are 51.73%, 41.37%, 3.45%and 3.45%.Underground water quality is generally good.The main influence factors of uncon-fined qualityⅥ,Ⅴ classification in chemical composition are ammonia nitrogen, SO4 2 -, total hardness ( CaCO3 ) and total dissolved solids. [Conclusion] The underground water quality in Huocheng area is generally good and suitable for drinking.
