摘　　要：红黄土壤经焙烧活化后 ,用工业废盐酸浸渍 ,向浸出液中加入适量活性硅酸 ,制备成聚硅酸氯化铝铁。研究了土壤的最佳活化条件 ,观察了该絮凝剂处理工业废水的效果。该絮凝剂利用本地丰富廉价的矿产资源和工业废酸为原料 ,价格低廉 ,具有良好的开发应用前景。Red and yellow soil is roasted and leached in industrial waste chlorhydric acid, obtaining a leach solution. Appropriate amount of activated metasilicic acid is added to the leach solution to produce PSAFC. This paper investigates the optimum conditions of activating the soils and examines the results obtained by using the flocculant to dispose industrial waste. This flocculant is cheaper and has development outlook due to full utilization of local mineral resources and industrial waste.
