摘　　要：介绍了用硫酸浸出赤泥生产净水剂的机理,对赤泥中铁、铝、硅等元素在不同条件下的溶出率进行了研究,并采用不同的碱性添加物调节赤泥溶出液的盐基度,使其具有最佳的絮凝效果。对产品进行了不同用量的污水净化试验,确定了最佳用量,净水效果优良,该方法值得进一步研究。This article introduced the mechanism that sulfuric acid leaching of purifying agent produced with the red mud, and researched the dissolution rates of red mud under different contents of iron, aluminum, silicon elements. The best flocculation effect was achieved by different alkaline additives adjusting the basicity of stripping solution. The purification experiment carried on sewage has showed puring ratio of sulfuric acid leaching is best, but the mechanism is still worth further studying.
