摘　　要：水溶性染料废水是印染废水中较难处理的一部分。采用合成的聚硅酸镁铁,利用吸附和混凝两种作用,其脱色效果高于粉末活性炭等其他吸附剂。试验表明,聚硅酸镁铁合成药剂投加量为1g/L、pH值11时,大部分水溶性染料废水经脱色后,色度接近于0。The water-soluble dyestuff effluent is the most difficult to disposal in dyeing and finishing effluent. A polymerized silicate containing iron and magnesium was prepared. With the function of adsorption and coagulation, that has a better decolor ization capacity than powder activated carbon. The color of most treated effluent was close to zero.
