摘要
采用醚化、磷酸酯化和接枝共聚等3种方法改性魔芋下脚料中提取的絮凝活性物,用以去除废水中油脂和Cr(Ⅵ)。反应时间、用量和pH等3因子正交实验表明,经醚化改性与磷酸酯化改性后的絮凝剂分别对油脂和Cr(Ⅵ)的去除效果较好。聚合氯化铝(PAC)用量、ZnSO4用量、pH和微波照射时间等4因子正交实验表明,PAC和ZnSO4可以强化改性絮凝剂效果,对2种污染物的吸附去除效果分别用双常数方程和Elovich方程能够较好地拟合。
Using three kind of methods （etherification, phosphoric esterification, graft copolymerization） to modify the flocculating active extraction from Konjae by-products, and applying it to remove the oil and Cr（ VI ） in wastewater. Orthogonal experiments with factors of reacting time, dosage and pH indicated that etherified floc- eulation and esterified flocculation can treat oil and Cr（VI） with optimum removal rate respectively. Orthogonal experiments with factors of poly-aluminum sulfate （PAC） , zinc sulfate （ZnSO4） , pH and microwave irradiation time showed that PAC and ZnSO4 can intensify flocculation effect. Using double constant equation and Elovich e- quation can fit the oil removal rate and Cr（V[） removal rate with a high de^ree of fittin~ respectively.
