摘要
文章研究了用无机絮凝剂硫酸铝、聚丙烯酰胺(PAM)和天然高分子絮凝剂壳聚糖(CTS)进行复配对景观水体的处理效果。实验结果表明:在硫酸铝、聚丙烯酰胺和壳聚糖投加量分别为99.5 mg/L、2.0 mg/L和2.0 mg/L时,絮凝效果最佳,CODCr和浊度的去除率可分别达67.4%与91.0%,与传统的Al2(SO4)3-PAM絮凝剂相比,CODCr和浊度的去除率分别提高了13.8%和4.7%,而且大大减轻了硫酸铝和聚丙烯酰胺对环境的二次污染,具有明显的环境效益。
The research a novel composite flocculant Al2（SO4）3-PAM-CTS prepared from aluminum sulfate,polyacrylamide（PAM） and chitosan（CTS） was used in the treatment of Landscape water.The experimental results showed that when the dosage of aluminum sulfate was 99.5 mg/L,PAM was 2.0 mg/L and CTS was 2.0 mg/L,the flocculation effect was best,the CODCr removal was 67.4 %,the turbidity removal was 91.0 %.Compared with traditional flocculants,the CODCr removal rate was increased by 13.8 % and the turbidity removal rate was increased by 4.7 %,The second pollution of aluminum sulfate and polyacrylamide（PAM） reduced greatly.These indicated that the Al2（SO4）3-PAM-CTS flocculant had obvious Environmental benefits.
