摘要
为初步掌握宁阳化工聚集区地下水水化学特征及受污染的总体程度,对该区10个调查点位的地下水进行了监测,结果表明:研究区水化学类型以HCO3.SO4-Ca型水、SO4.Cl-Ca.Na型水为主,除西南侧区域3个点矿化度小于1.5 g/L,属于A类外,其它7个点均大于1.5 g/L,属于B类水,地下水水质较差,矿化度较高,且北部区域水质稍好于南部区域;单因子评价结果显示地下水主要污染因子为三氯甲烷、四氯化碳、克百威、硝酸盐和氨氮,均为重污染,主要集中在化工聚集区南部区域,这可能与该处化工企业集中分布有关。
In order to master the chemical characteristics of groundwater and the overall level of contamination in the chemical concentrated area of Ningyang County,the groundwater was monitored at 10 survey sites in the area.And it turns out:The hydrochemical types in the study area are mainly HCO 3.SO 4-Ca type water、SO 4.Cl-Ca.Na type water.Except for the South area,the mineralization degree of 3 spots is less than 1.5g/L and belongs to Class A,the other 7 points are all more than 1.5g/L and belong to Class B water.The quality of groundwater is poor and the mineralization degree is high,and the water quality of North area is slightly better than that of South area.The results of single factor evaluation showed that the main pollution factors of groundwater were chloroform and tetrachloromethane,which were moderate and heavy pollution respectively,and mainly concentrated in the south of the chemical concentration area,which might be related to the concentration distribution of chemical enterprises there.
