摘　　要：采用浙江平阳明矾渣，通过焙烧氨浸取，盐酸反应制备新型复合絮凝剂—ＰＡＣＦ．新工艺中Ａｌ２Ｏ３提取率达６３．４％．并得到副产品钾氮复合肥。This paper illustrates a new technique of preparing PACF from Pingyang alum dregs in Zhejiang Province by hydrochloric reaction after roasting and ammonia immersing. The extraction rate of alumina arrives at 63 4%. Through the new method,the by-product of K-N compound fertilizer can be obtained and the stability of PACF improved.
