摘要
采用催化臭氧化技术对降解苯酚进行研究。考察了进气流量、苯酚初始浓度、催化剂投加量、pH值及温度等因素对苯酚降解的影响。研究结果表明：在一定范围内,随着进气流量的增加、温度的降低,苯酚的降解速率加快;溶液pH值对催化臭氧化有比较重要的影响,在pH值为8-10时,苯酚的去除率最高。
The catalytic ozonation technique was used to treat phenol wastewater. The influences on the removal efficiency of the ozone flow rate, the initial phenol concentration, the amount of catalyst, temperature and the initial pH value were investigated. The results show that, under certain conditions, the phenol removal efficiency increased along with the increase of the ozone flow rate and the decrease of temperature. Meanwhile, the initial pH value had an important effect on the phenol removal efficiency, which was greatest when the pH value was in the range of 8 to 10.
