摘要
在地下水接触氧化法除铁除锰过程中,分别对比了优质锰砂、纤维球、活化沸石3种不同性能滤料的除铁除锰效果、反冲洗强度及运行周期等运行参数.研究结果表明,纤维球、活化沸石滤料均能除铁,具有反冲洗强度小,反冲洗耗水量小的优点;优质锰砂滤料具有较好的铁锰同时去除的效果.
Three kinds of filtration materials including high -quality manganese sand , fiber ball and activate stone were applied to remove iron and manganese in groundwater by contact oxidation process. The effect of the filtration materials to remove iron and manganese were compared respectively. The operational parameters of backwashing rate and operational period were researched in this paper. The test results showed that fiber ball and active zeolite could remove iron, moreover fiber ball and active zeolite for removing iron had some advantages such as lower backwashing rate and so on. High - quality manganese sand was capable of removing iron and manganese simultaneously.
