摘 要：
通过浸溶试验,研究p H、有机质、铵态氮及氧化还原条件对矿区地下水中Fe(Ⅱ)转化的影响,并且通过正交试验确定各变量对铁元素溶出影响的主次顺序以及最佳溶出条件、最佳抑制条件。通过极差分析,发现p H对溶液中Fe(Ⅱ)浓度的影响最大,腐殖酸含量、氯化铵浓度次之;Fe(Ⅱ)最佳溶出条件为:p H 3,腐殖酸含量1.5 g/L,氯化铵浓度0。在此试验条件下,Fe(Ⅱ)的溶出浓度达到4.061 mg/L。Fe(Ⅱ)最佳抑制条件为:p H 7,腐殖酸含量0.5 g/L,氯化铵浓度50 mg/L。在此条件下,Fe(Ⅱ)的溶出浓度仅为0.193 mg/L。该研究通过掌握矿区地下水中各环境因素对Fe(Ⅱ)浓度的影响,对控制地下水中的铁污染有一定的指导意义,并且能够缓解饮用水短缺的问题。

摘 要：
The effects of pH value,organic matter,ammonia nitrogen and oxidation reduction on the transformation of Fe( Ⅱ) in groundwater in the mine area were studied through the leaching experiment,and the order of the influence of iron element dissolution and the optimal dissolution conditions and the optimal inhibition conditions were determined through orthogonal experiment. The range analysis showed that,the effect of p H value on the concentration of Fe( Ⅱ) was maximum,followed by the humic acid content and ammonium chloride concentration. The optimal dissolution conditions were as follows: the value of p H was 3,the humic acid content was 1. 5 g / L,the ammonium chloride concentration was 0,under the experimental conditions,the dissolved concentration of Fe( Ⅱ) could be as high as 4. 061 mg / L; and the optimal inhibition conditions were as follows: the value of p H was 7,the humic acid content was 0. 5 g / L,the ammonium chloride concentration was 50,under the experimental conditions,the dissolved concentration of Fe( Ⅱ) was only 0. 193 mg / L. This study can provide some certain guiding significance for the treatment of groundwater from grasping the effects of environmental factors on Fe( Ⅱ) concentration in groundwater in the mining area,and also can ease the shortage of drinking water.
