摘要:
采用聚合氯化铝铁(PAFC)分别与3种电荷类型聚丙烯酰胺(阳离子聚丙烯酰胺(CPAM)、阴离子聚丙烯酰胺(APAM)、非离子聚丙烯酰胺(NPAM))复配对含酚高浓度有机废水进行预处理,重点探讨复配絮凝剂对浊度、总酚和化学耗氧量(COD)的去除效果。对3种电荷类型有机絮凝剂进行筛选,研究结果证明PAFC与CPAM复配后絮凝效果最优。采用单因素试验和正交试验探讨PAFC投加量、CPAM投加量、pH和水力条件对含酚高浓度有机废水絮凝预处理效果的影响。结果表明:在pH为5、PAFC为1.5 g/L和CPAM为20 mg/L,以300 r/min快速搅拌1 min和50 r/min慢速搅拌10 min时处理效果最佳,对浊度、总酚和COD最佳去除率分别为99.1%、37.5%和51.4%。
Abstract:
The organic wastewater with high concentration chemical oxygen demand(COD)and phenol was pretreated by poly aluminum chloride iron(PAFC)and three charge types of polyacrylamide(cationic polyacrylamide(CPAM),anionic polyacrylamide(APAM),and nonionic polyacrylamide(NPAM))with the emphasis on the removal efficiency of turbidity,total phenols and COD.Three kinds of organic flocculants were screened and cationic polyacrylamide(CPAM)was selected to be complexed with PAFC.The effects of dosage of PAFC,dosage of CPAM,pH and hydraulic condition were investigated by single factor experiments and orthogonal experiments.Results showed that when the pH was 5,1.5 g/L PAFC and 20 mg/L CPAM were added,and the mixture was stirred at 300 r/min for 1 min and 50 r/min for 10 min,the removal rates of turbidity,total phenols and COD were 99.1%,37.5% and 51.4%,respectively.
