摘要

采用臭氧/超声联合降解含对氨基苯酚模拟废水.研究了对氨基苯酚降解的影响因素和动力学，考察了反应液初始pH 值、反应物初始浓度、臭氧投量、反应温度对臭氧/超声降解对氨基苯酚反应速率的影响.结果表明，对氨基苯酚初始浓度为1000 mg·L-1时，pH 11.0，臭氧投量88 mg·min-1，超声密度0.3 W·ml-1，常温下反应30 min后对氨基苯酚去除率达99％以上.对氨基苯酚的臭氧/超声降解符合表观一级动力学，得到幂指数方程描述反应动力学.

Abstract

The degradation of 4-aminophenol (PAP) in aqueous solution with the combination of sonolysis and ozonation was investigated with laboratory-scale experiments.The effects of pH value

ozone dose

ultrasound energy density and reaction temperature on the reaction kinetics were investigated.Experimental results showed that ozonation combined with sonolysis was effective for the treatment of PAP and up to 99% of PAP was removed after 30 min reaction with ozone dose 88 mg·min-1

pH value 11.0

ultrasound energy density 0.3 W·ml-1

and room temperature.In all cases

the degradation of PAP followed pseudo-first-order kinetics.A simplified model for PAP degradation was derived by accounting for the contribution of pH value

ozone dose

ultrasound density and reaction temperature in the O3/US system.
