摘要
浑河冲洪积扇部分区域的地下水水质检测结果表明,区域环境水文地球化学场与地下水中的氮转化关系密切,尤其是含水层的岩性组合和锰离子浓度场控制着地下水中氮的存在形式。铁离子对氮转化的影响相对较弱。在地下水呈弱酸性的条件下,其影响因素还包括耗氧量、氯离子和硫酸盐。总硬度和总固体与硝酸盐氮呈显著正相关,与氨氮未表现出相关关系。
The groundwater quality is monitored in some area of the Hun river' alluvial and flood fan. The results illustrate that the close relationship of nitrogen transform with environmental hydro-geochemical field exists. The concentration field of manganese ions as well as the different lithologic constitutions of the aquifer, in particular, controls the existing forms of nitrogen in groundwater. By contrast, the effect of iron ions on nitrogen transform is relatively insignificant. The other influence factors include oxygen demand, chlorine ion and sulfate with the groundwater being weak acidity. Total hardness and total solids appear positive correlation with nitrate, but no correlation with ammonium.
