惠安县地下水水质变化趋势的分析探讨

通过对惠安县16个乡镇地下水的赋存条件、富水程度以及地下水的分布特征进行分析研究,认为各乡镇地下水的水质均遭受不同程度污染,从抽查的118个水样中发现,水质良好、较好的有57件,占48%,水质较差的样品61件,占52%.超标项目主要有pH值、三氮、Mn^2＋等.并对地下水污染、地下水水质变化趋势进行分析探讨,提出防治措施和对策.

Discussion on the Variant Tendency of Groundwater Quality in Huian County

Based on the analysis results of the occurrence, water abundance and distribution characteristics of underground water in the sixteen villages and towns of Huian County, it is considered that the ground water in the surveyed area has suffered from a variable degree of pollution. Among the 118 spot-check water samples, there are 57 samples of satisfactory water quality (taking the total of 48 percent) and 61 samples of less satisfactory water quality (taking the total of 52 percent).The major transnormal items include pH values, tri-nitrogen and the ions Mn~(2+).The development tendency of the groundwater pollution and groundwater quality are also under discussion. Finally, some control measures and countermeasure against the groundwater pollution are put forward in the paper.
