摘要
由精矿粉和氧化铁磷加工而成的铁质多孔性物质对含铬废水的处理试验结果表明:该铁质多孔滤料的粒径为1.45～2.00mm,废水的pH值为5～6,温度在约20℃的情况下,六价铬的去除率可达95%,同时总铬的去除率达80%以上。
Tests were carried out for the treatment of chromium containing wastewater using a porous ferrous material made from concentrated breeze and ferric oxide.The result shows that when the particle size of the porous ferrous filter material is 1.45-2.00 mm,the pH value is 5-6 and the temperature is 20 ℃,the removal rate of Cr6+may reach 95%and that of total chromium may exceed 80%.
