摘要
内陆地区地下水咸化有别于海水入侵,以焦作市为例,利用不同水体的稳定同位素(如O18和H2)和水化学组成,判定地下水咸化来源。结果发现,焦作市深层地下水氯化物浓度升高与工业废水有关,工业废水借助断层破碎带对研究区深层地下水(D8)产生影响;焦作市浅层地下水氯化物浓度升高与工业废水和生活污水的混合水有关,混合水透过河床底部包气带进入浅层地下水对其产生影响。泉水、农业面源和大气降水不是研究区地下水氯化物污染的来源。
Inland groundwater salinization was different from seawater intrusion,and in Jiaozuo City,stable isotopic(e.g.O18and H2) and hydrochemical compositions of different water bodies were introduced to determine groundwater salinization sources.Results indicated that chloride pollution in deep groundwater was connected with industrial waste water which found its way into groundwater(D8) through faults and fractures,and chloride pollution of shallow groundwater was related with sewage which was mixed with industrial waste water,and then infiltrated into shallow groundwater through the unsaturation zone.Spring water,agriculture non-point source and local precipitation had no influence on chloride pollution of local groundwater.
