| 摘 要： | 用硫铁矿渣和硫酸铝渣制备了聚硅酸硫酸铁．研究了影响硅酸聚合的条件和nFe／nSi对聚硅酸硫酸铁稳定性的影响．用研制的聚硅酸硫酸铁絮凝剂处理模拟浊水，当nFe／nSi比为0．5时絮凝效果为最佳，用量达0.5ml／L后除浊率便可达90％以上；用nFe／nSi比为1．5的聚硅酸硫酸铁处理垃圾填埋场渗沥液，CODCr的去除率达60％．聚硅酸硫酸铁的特点是形成矾花的速度快，矾花实，沉降迅速．

| Abstract: | The polyiron silicate sulfate flocculants (PFSS) were made from pyrite cinder and bauxite sledge. The conditions of polymerization of silicate acid and the effect of n_(Fe)/n_(Si) on the stability of PFSS were studied. The prepared PFSS was applied to treat simulating turbid water, the results of treatment showed: the PFSS of n_(Fe)/n_(Si)=0.5 had a better turbidity reducing than that of other n_(Fe)/n_(Si) values, the removal rate of turbidity was above 90% in the addition of 0.5ml/L of n_(Fe)/n_(Si)=0.5 PFSS. The treatment of fillland leachates showed that the COD_(Cr) of fillland leachates lowered 60% using PFSS of n_(Fe)/n_(Si)=1.5. The characters of PFSS were that the vitriol flowers grew rapidly, became big and sturdy, then settled out fast. |
