磁力搅拌/臭氧法降解对氨基苯酚模拟废水的研究

Research on the degradation of simulative wastewater containing p-aminophenol by magnetic stirring/ozone process

采用磁力搅拌/臭氧法降解含对氨基苯酚模拟废水,研究了影响对氨基苯酚模拟废水降解的各因素,考察了反应液初始浓度、初始p H、臭氧投量、反应温度、常见无机离子等因素对臭氧氧化降解对氨基苯酚反应速率的影响。结果表明,在25℃、p H=4.52、初始质量浓度为100 mg/L、臭氧投加量为50 L/h,反应30 min时,对氨基酚的去除率达95.2%,盐的存在不同程度地降低了臭氧降解效果。

Abstract： The simulative wastewater containing p-aminoplenol （PAP） has been degraded by magnetic stirring/ ozone process. Various factors that have influences on the degradation of PAP are studied. The effects of the initial concentration of reaction liquid, initial pH, ozone dosage, reaction temperature and common inorganic ions, etc. on PAP reaction velocity treated by ozonation degradation are investigated. The results show that PAP removing rate reaches 95.2%, when the temperature is 25 ℃,pH=4.52,initial mass concentration 100 ng/L, ozone dosage 50 L/h, and reaction time 30 min. The ozonation degradation effect is lowered to different degrees owing to the presence of salt.
