淄博孝妇河流域孔隙水硫酸盐污染特征及其形成

Characters and formation reasons of sulfate contamination in pore water of Xiao Fu River Basin in Zibo City

分析 1 989～ 1 996年孔隙水的水化学资料 ,总结出了研究区孔隙水硫酸盐污染的特点。借助原状土柱试验探明 ,孔隙水中污染组分来源于农业灌溉污水。农灌的频率与强度及大气降水的特点共同决定了本区孔隙水污染特征的形成。因此 ,停止或减少污灌量是改善地下水环境的有效且经济的方法。

s:According to analysis of aquatic chemistry data during 1989～1996,the characteristics of sulfate contamination in pore water were found.By the soil column experiment,it was confiramed that the contaminants in the pore water came from the irrigating sewage,and the irrigation frequency and quantity were the main factors to decide the characteristics of pore water contamination.Therefore,effective control of sewage irrigation is an effective and economic way to improve groundwater environment.
