摘　　要：二甲基二烯丙基氯化铵(DMDAAC)、甲基丙烯酰氧乙基三甲基氯化铵(DMC)、衣康酸(IA)、富马酸(FA)以不同配比共聚合成絮凝剂P(DMDAAC/DMC/IA/FA),得到絮凝剂I和II。研究了絮凝剂I和II对印染废水、钻井废水絮凝效果;由电镜扫描观察得到絮体的形貌图,非线性分维计算了絮体形貌的空隙分维数。结果表明,絮凝剂I在p H^8、投加量为0.75g/L时,对印染废水的CODCr去除率是45.9%;絮凝剂II在p H^10、投加量0.25g/L,对钻井废水的CODCr去除率为73.4%。不同合成条件得到的絮凝剂处理不同的废水效果不同。非线性分维数计算与试验结果一致。New polymers of flocculant were synthesized by diallyl dimethyl ammonium chloride（ DMDAAC）,methacryloxyethyltrimethyl ammonium chloride（ DMC）,itaconic acid（ IA）,fumaric acid（ FA）. The effects of different dosage on dyeing wastewater and drilling wastewater were discussed,and the morphology of flocs was observed by scanning electron microscopy. The results indicated that CODCrremoval ratio of dyeing wastewater was 45. 9%using flocculant I when p H ~ 8 and 0. 75 g/L dosage,and CODCrremoval ratio of drilling wastewater was 73. 4% using flocculant II when p H ~ 10 and 0. 25 g/L dosage. The two flocculants had different effects in treating dyeing and drilling wastewater. The nonlinear fractal dimension calculation were consistent with the experimental results.
