| 摘 要： | 为了解决煤矿灰岩水铁含量高,较难复用的问题,进行了接触过滤氧化法处理模拟含铁原水的试验研究。结果表明:采用石英砂滤料的接触过滤氧化工艺处理铁含量为2.0mg/L的模拟原水除铁效果明显,当气水比为2.0,pH值为7.5~8.0,停留时间小于2~3min,滤速为12.0m/h时,除铁率可达90%以上,滤后水满足铁含量0.3mg/L的井下复用水质要求,且过滤周期长达36h;同时分析得出最大平均催化氧化速率系数为KFe2+=1.50×1011L3mg-3s-1和除铁拟合曲线方程-Ln(Ct/Co)=-0.0011x2+0.0517x+1.748。

| Abstract: | To solve the problems for reuse of limestone water with high iron concentration, the experimental study on treatment of the simulated water containing iron by contact filtration oxidation was conducted. The results show that the treatment effects of the simulated water by contact filtration oxidation with quartz sand filter material was obvious. The iron removal rate could reach above 90 % under the conditions of gas/water ratio of 2.0, pH value of 7.5-8.0, residence time less than 2-3min and filtration velocity ofl2.0m/h. The limit requirements of total iron concentration content less than 0.3mg/L for underground reuse water quality requirements can be met and the filter cycle of 36 hours can be achieved. After analyzing, the maximum average catalytic oxidation rate coefficient KFe2＋=1.50×10^11L3mg-3s-1, and the iron removal curve fitting equation is -Ln（Ct/Co）=-0.0011x2＋0.0517x＋1.748. |
