摘要: 采用原位聚合法，在聚丙烯酰胺的聚合过程中引入金属离子进行改性，合成了一种新型改性聚丙烯酰胺。通过正交实验确定了改性聚丙烯酰胺的最佳合成条件。红外图谱显示，该聚丙烯酰胺是一种具有特殊结构的有机高分子化合物。以污泥脱水率和污泥比阻为考察指标，研究了改性聚丙烯酰胺对污水处理厂剩余活性污泥脱水性能的影响，结果表明，在每1 000 kg干污泥投加改性聚丙烯酰胺2.6 kg的条件下，污泥含水率由94.3%降至80.1%，污泥比阻由1.24×1013m/kg降至1.05×1011m/kg。

Abstract: A novel modified polyacrylamide was synthesized through in-situ polymerization of acrylamide during which the metal irons was added into the reaction system. The optimum synthesis conditions were determined by orthogonal experiment. The infrared spectra show that the modified polyacrylamide is a high molecular polymer with special structure. The dewatering rate of sludge and specific resistance of sludge were employed to investigate the effect of modified polyacrylamide on dewatering performance of sludge. The results show that soil moisture can be reduced from 94.3% to 80.1% and specific resistance of sludge can be reduced from 1.24×1013m/kg to 1.05×1011m/kg when 2.6 kg modified polyacrylamide was added into the 1 000 kg dried sludge.
