| 摘 要： | 根据现场取样分析,对张集水源地重要补给水源孔隙水水化学特征进行了总结和区分,分析了潜水动态特征及其对水源地开采的影响,提出了相应的环境保护措施。得出主要结论:(1)孔隙水水化学类型虽然较复杂,但以HCO3-Ca、HCO3-Ca·Mg型为主,其次是Na+ 含量较高的地下水类型,局部地段点出现Cl-含量较高的地下水类型;(2)氨氮、亚硝酸盐、硝酸盐以及高锰酸盐等组分含量有不同程度的超标;(3)水源地开采后,孔隙水为水源地重要的补给水源,在制定水源地环境保护方案时应予考虑。

| Abstract: | Based on experimental data of the samples,the characteristics of chemical components of pore water quality are analyzed,summed and classified.And its influence in Zhangji Well Field is analyzed.Some suggestion is put forward for the protection of the well field.The results show that:①Although complex,the common types of the chemical component of pore water are HCO3-Ca·Mg or HCO3-Ca;the following are the types with Na+;the next are the types with Cl-.②Some components such as NH4+,NO2-,NO3- and COD MN overtop the standard samples in different degree.③After the well field is exploited,pore water resources will become an important recharge source,and it has an important influence on the well field.So it must be considered in making a plan for the rational exploitation,scientific management and protection of resources in Zhangji Well Field. |
