| 摘 要： | 以聚二甲基二烯丙基氯化铵(PDMDAAC)为有机改性剂,制备了聚二甲基二烯丙基氯化铵(PDMDAAC)-聚硅酸铝铁(PSAF)复合絮凝剂,考察了复合pH、物料配比、温度及时间等因素对PDMDAAC-PSAF絮凝性能的影响。研究发现,PDMDAAC-PSAF复合絮凝剂的最佳制备条件为:复合pH为10,m(膨润土)∶m(PDMDAAC)为200∶1,温度为60℃,反应时间为1h。此条件下获得的复合絮凝剂(质量分数为8%),在投加量为1.5%(絮凝剂与模拟染料废水体积比)时,对活性艳蓝染料模拟废水脱色率达87.7%。相比较PSAF絮凝剂(脱色率77.1%),PDMDAAC-PSAF复合絮凝剂显示出更好的絮凝脱色效果和应用前景。

| Abstract: | PDMDAAC was prepared as organic modifier of PSAF.The inorganic-organic composite flocculants PSAF-PDMDAAC were prepared for wastewater treatment.PSAF-PDMDAAC composite flocculant was studied in optimum preparation conditions for the composite pH,compound ratio,composite temperature,compound time,compound dosage,and so on.The optimum preparation is that the composite pH 10,m(bentonite)∶m(PDMDAAC)=200∶1,composite temperature is 60 ℃,compound time is 1 h.When the dosage was 1.5%(volume ratio of flocculant and water),removal of reactive blue dye wastewater rate was 87.7%. |
