摘要
制备了聚合氯化铝-壳聚糖复合絮凝剂PAC-CTS,考察了复合反应条件PAC与CTS的质量比、反应pH和复合反应时间对复合絮凝剂絮凝效果的影响,得出最佳复合条件。探讨了其投加量、废水pH对城市生活污水絮凝效果的影响。结果表明,其最佳的复配条件是PAC∶CTS=3∶1,pH=4,反应时间为2 h。其处理废水的最佳投加量为80 mg/L,最佳pH为7。
The composite flocculants PAC-CTS were prepared for wastewater treatment.The influence of different composite conditions has been investigated under the PAC-CTS quality ratio,and pH of reaction.The results showed that the best conditions of reaction were as follows： PAC-CTS quality ratio=3∶1,pH=4,reaction time=2.And the best conditions of application in wastewater treatment were as follows： PAC-CTS dosage=80 mg/L,pH=7.
