| 摘 要： | 采用机械混合的方法,将微生物絮凝剂MBF8与植物胶粉羧甲基改性絮凝剂CG-A复合制备了新型高效复合生物絮凝剂CBF-1.采用FT-IR、zeta(ξ)电位、透射电镜分析,确定了CBF-1的特征官能团、电荷性及分子胶束形态等物化性质;采用烧杯絮凝实验,探究了CBF-1的絮凝特性.结果表明,制备CBF-1的最佳CG-A∶MBF8质量复合比为4∶6;CBF-1为含少量沉淀物的淡黄色液体(不溶物0.013%),有效成分为0.5%,pH6.1,相对粘度1.72;有效成分0.1%时等电点约pH1.5;主要特征官能团有羟基、羧基、氨基、酰胺基及磷酸基.采用PAC(3mg·L-1)+CBF-1(1.0～8.0mg·L-1)复配絮凝,适用的pH为6.0～10.0,离子强度为0.5～5.0mmol·L-1;对浊度100NTU的高岭土悬浊液,在最佳条件PAC(3.0mg·L-1)+CBF-1(1.0～2.0mg·L-1),pH8.0,离子强度3.0mmol·L-1下,浊度去除率>92%,残余铝<75μg·L-1;对浊度6～300NTU的水,浊度去除率为61%～98%.
