| 摘 要： | 本文采用活性炭负载TiO2作催化剂对臭氧氧化去除含酚废水进行了研究．研究了不同的酚初始浓度、pH值及臭氧浓度对苯酚去除率的影响，获得了反应动力学常数．实验结果表明：苯酚初始浓度越小，去除率越高．在本实验条件下，向150mL苯酚溶液中通入浓度为3．48mg/L、流量为0．05m^3／h的臭氧化空气反应30min去除率即可达到99％以上。

| Abstract: | Phenol in water was removed by ozonation with the catalysis of TiO_2-mounted activated carbon. In this experiment, the effects of factors such as the initial concentration of the phenolic solution, pH value and the concentration of the ozone ,on the removal efficiency of phenol were investigated. The reaction kinetics and its constant was investigated. On the studied conditions, pumped the mixed ozone at the concentration of 3.48 mg/L and 0.05 m3/h, after 30 mins, 99 % of the phenol was removed. |
