摘　　要：利用炉渣的性质制成炉渣基透水材料,研究对六价铬离子的去除效果。在试验条件下,分析骨料配比和水泥的比例对样品的影响,确定在骨料配比(细粒:中粒=2∶1)和对水泥的比例为2∶1时,样品对重铬酸根离子的去除效果较好,即1 cm厚炉渣基透水砖对六价铬离子三次透过后的去除率高达78.50%,而对于10 cm透水填料柱,一次性对高浓度重铬酸根离子的去除率就可达到99.32%。The slag with its nature is made into permeable material,and is stapied to study the removal effere of the hexavalent chromium ions.In the experimental conditions the paper,analyses of the inpuenceof the ratio of aggregate and cement ratio on the samples,determines the ratio of the aggregate（fine： medium grain=2∶1） and the ratio of cement are 3：1,The samples of the dichromate ion removal is better,that is 1cm thick slag based on the hexavalent chromiumion permeable brick as high as 78.50% removal rate through the post three times,while the 10cm permeable filler column,once on the high concentration of dichromate ion removal rate can reach 99.32%.
