  • 摘要: 用聚二甲基二烯丙基氯化铵（PDM）、聚合氯化铝（PAC）按照质量比1%制备了复配混凝剂，研究了其理化特性及原水污染物去除效果。利用Al-Ferron逐时络合比色法研究了复配混凝剂的铝（Ⅲ）形态分布，结果表明，Ala、Alb和Alc分别占12.62%、16.02%和71.36%。复配混凝剂Zeta电位平均值为41.6 mV。红外吸收光谱分析表明复配混凝剂的羟基缔合程度比PAC要高。扫描电镜结果表明，固体复配混凝剂表面较为粗糙、结构疏松。相同投加量时，复配混凝剂对江河水、水库水的浊度、CODMn、UV254的去除效率均优于PAC。实验利用针杆藻人工模拟高藻原水，当投加PDM：PAC质量比10%的复配混凝剂10 mg/L时，复配混凝剂对藻类的去除率为80.5%。
    Abstract: The composite coagulants were prepared by poly (dimethyldiallylammonium chloride) (PDM) and poly aluminum chloride (PAC) at mass ratio of 1% in this study. Research on physico-chemical properties of composite coagulants was done, and removal efficiency of pollutants in raw water with composite coagulants was also investigated. Aluminum species distribution of composite coagulants was investigated by Al-Ferron complexation timed spectrophotometry. The result shows that proportions of Ala, Alb and Alc were 12.62%, 16.02%, 71.36%, respectively. The average Zeta potential of composite coagulants was 41.6 mV. The level of hydroxyl radical association of composite coagulants was higher than PAC, when infrared absorption spectrograms of composite coagulants and PAC were compared. The result of scanning electron microscope test revealed that composite coagulants had coarse surface and loose microstructure. The removal rate of turbidity, CODMn and UV254 with composite coagulants was higher than with PAC, when coagulant dosage was same in treatment of river and lake water. Simulated algae-rich water was prepared by Synedra, composite coagulants were prepared by PDM and PAC at mass ratio of 10%, removal rate of algae was 80.5% when the dosage of composite coagulants was 10 mg/L.
