【摘要】 综述了国内外处理含聚丙烯酰胺废水采用的物理化学法和生物降解法,对各种方法的除污机理、处理效果及优缺点进行了总结和分析。物理化学法主要包括絮凝沉淀法、光催化法、高级氧化法、超声波法、电渗析法等,易造成二次污染;生物降解法周期较长,但可解决二次污染的问题。从安全经济的角度出发,采用生物降解法或物理化学与生物联合处理的方法更为合理有效。更多还原

【Abstract】 Several physical-chemical and biological processes used for treatment of polyacrylamide-contained wastewater at home and abroad are reviewed.The removal mechanism,treatment effect and characteristics of each process is summarized and analyzed.The physical-chemical processes including flocculating settling,photocatalytic oxidation,advanced oxidation,ultrasonic treatment,electrodialysis,etc may result in secondary pollution.Biological processes will take a relatively longer time,but can avoid secondary pollution.In consideration of safety and economy,biological processes or physical-chemical and biological combined processes will be more reasonable and effective.更多还原
