摘要:以钛白粉副产品七水硫酸亚铁和工业含铝材料为原料,研制了1种无机高分子复合絮凝剂
聚合硫酸铁铝(PFAS)用于印染废水处理,通过扫描电镜分析发现新合成的聚合硫酸铁铝具有独特
的空间立体褶皱状结构。在单因素的基础上,探究了pH和PFAS授加量对印染废水的COD、浊度
去除效果和形成污泥体积的影响,以及PFAS与常见絮凝剂(PFS、PAC和CPAM)对印染废水除
COD、除浊效果和生成污泥体积的比较研究。试验结果表明:当PFAS投加量为0,30g/L,pH为
8.5时,印染废水的COD去除率达到83.0%,浊度去除率可达到95.0%,生成污泥体积为
52.8mL,PFAS对印染废水的COD和油度去除效果优于PFS、PAC和CPAM

Abstract: Polymeric aluminum ferric sulfate (PFAS) was developed by Industrial Grade ferrous sulfate
heptahydrate and industrial aluminum sulphate (16% Al2o, ) PFAS was used for printing and dyeing
wastewater treatment. The new synthetic Polymeric aluminum ferric sulfate(PFAS) with a unique spatial
fold-like structure was discovered by scanning electron microscopy analysis(SEM). The treatment efficiency was
evaluated by investigated sludge volume and the reduction of removal rate of COD and turbidity of printing and
dyeing wastewater by using single factor. The results show that the removal rate of COD is achieved 83.0%, the
removal rate of turbidity is achieved 95. 0% and the sludge volume is 52.8 ml. when the coagulant dosage is
0.3 g/I and PH is 8. 5. Meanwhile, compared with the common coagulant(PFS, PAC and CPAM)in application
of printing and dyeing wastewater treatment, the performance on the removal of COD and turbidity of self-make
PEAS is better than those of PFS, PAC and CPAM
