【摘要】 本文以聚合氯化铝(PAC)和二甲基二烯丙基氯化铵均聚物(PDMDAAC)为原料,制各出了聚合氯化铝(PAC)-二甲基二烯丙基氯化铵均聚物复合絮凝剂(PDMDAAC),采用透射电镜研究其结构形貌,并试验了处理黄河水的絮凝效果。研究结果表明,PAC-PDMDAAC较PAC具有更大的枝化度和更好的絮凝效果。更多还原

【Abstract】 A composite flocculants polyaluminum chloride (PAC) - polydimethyldiallyammonium chloride (PDMDAAC) were prepared by using PAC and PDMDAAC as raw materials. And the framework characteristic of PDMDAAC was studied by TEM. The effect of dilutedness and aging on the framework characteristic of the composite flocculant was also investigated. The experimental results show that the framework characteristic of PAC-PDMDAAC is different from that of PAC, due to the interaction of PDMDAAC and PAC. The interaction of PDMDAAC and PAC will affect the coagulation-flocculation of composite flocculant Because the composite flocculant has higher degree of grafting, it should give better coagulation-flocculation effect The coagulation of the composite flocculant for the water from huang river demonstrates that the inference above is correct更多还原
