摘　　要：研究了磁场作用下聚二甲基二烯丙基氯化铵(PDMDAAC)、聚合氯化铝铁(PAFC)和磁粉复配去除淡水藻华,结果表明PDMDAAC、PAFC、磁粉的用量分别为0.18、1.4、10mg·L-1时,在0.5T的外磁场作用下富集2min效果最好。浊度、叶绿素a、总氮、总磷、COD、磷酸酶活性分别降低96.0%、97.4%、67.1%、95.6%、92.6%、97.1%,并初步研究了复配物除藻的机理。Removal of algal blooms in freshwater with compounds ofPDMDAAC, PAFC and magnetic power was studied. Under the condition of the amounts of PDMDAAC, PAFC and magnetic powder were 0.18 mg·L^-1, 1.4 mg·L^-, 10 mg·L^-, it was most effective to remove algal blooms assembled by 0.5 T magnetic field for two minutes. The removal rate of turbidity, chlorophyll-a, TN, TP, COD ,phosphatase activity were 96.0%,97.4%,67.1%, 95.6%,92.6%,97. 1% respectively, and the mechanism of removal of alga with the compounds was explored preliminarily.
