摘　　要：采用水溶液聚合方法制备两种两性高分子絮凝剂p(DMDAAC-co-FA)和p(DMC-co-DMAEMA-coAMPS)。对两种共聚合产物进行了傅里叶红外光谱(FT-IR)结构表征。用两种絮凝剂对印染废水进行絮凝试验的结果显示,絮凝剂p(DMDAAC-co-FA)在pH^7、投加量120 mg·L^(-1)时,CODCr去除率79.2%,色度去除率95.0%;絮凝剂p(DMC-co-DMAEMA-co-AMPS)在pH^7、投加量140 mg·L^(-1)时,CODCr去除率75.3%,色度去除率92.0%。通过对絮凝试验的絮体进行电镜扫描分析,采用非线性数学分形理论盒子法计算絮体形貌的空隙分维数Df,结果表明,絮体形貌的空隙分维数理论计算值与试验结果相符。Two novel flocculants,p(DMDAAC-co-FA)and p(DMC-co-DMAEMA-co-AMPS)were synthesized in aqueous solution.The products were characterized with FT-IR. The results of flocculation experiments showed that the removal ratio of CODcr andchroma were 79. 2%and 95. 0%at pH=7 with a dosage of 120 mg·L-1 p(DMDAAC-co-FA. In addition,the removal ratio of CODcrand chroma were 75. 3%and 92. 0%at pH=7 with a dosage of 140 mg·L-1 p(DMC-co-DMAEMA-co-AMPS). The fractal dimensionwas computed on analyzing dyeing wastewater flocs SEM and using sand box method of Non-liner fractinal theory,and the results offlocculation showed that the experimental results were consistent with the theorical computation.
