| 摘 要： | 以聚合硫酸铝铁(PAFS)与阳离子聚丙烯酰胺(CPAM)为原料,制备PAFS-CPAM复合混凝剂。通过Ferron法对产物的铁铝形态分布进行定量分析,用扫描电镜对产物的结构进行表征。采用响应面分析法通过建立CODCr去除率与各因素之间的Box-Behnken数学模型,对复合PAFS-CPAM的工艺进行优化。PFAS/CPAM最优制备工艺条件为:反应温度、反应时间和Fe/CPAM质量比分别为61℃、74 min、28。在最佳投加量50 mg·L-1条件下,优化制备的PAFS-CPAM对生活污水CODCr去除率、浊度去除率分别达80.86%、97.50%。

| Abstract: | The composite flocculant was prepared by polymerizing CPAM(a cationic flocculant P:acrylamide-methacryloxyethyltrimethyl ammonium chloride-acryloxyethyltrimethyl ammonium chloride)and PFAS(polymeric aluminum ferric sulfate).The morphological distribution of Fe and Al was studied by using Ferron analysis,and the morphology of the copolymer was observed using scan electron microscopy.The Box-Behnken mathematical relational model between CODCr removal rate and affecting factors was established,and the technique composing PAFS-CPAM was optimized.The optimum synthesis conditions were: react temperature 61℃,react time 74 min,and Fe/CPAM mass ratio 28,respectively.At these optimized conditions and using 50 mg·L-1 PAFS-CPAM flocculant prepared,CODCr removal and turbidity removal rates were 80.86% and 97.50%,respectively. |
