纳米TiO_2光催化处理采油废水研究

A Study on treatment of Oilfield Wastewater through nano-particle TiO_2

纳米二氧化钛为光催化剂,UV为光源,对采油废水进行光催化降解处理。考察了初始pH值、光照时间、催化剂投加量及H2O2与Fe3+因素对采油废水光催化处理效果;用XRD和SEM等分析方法对催化剂进行了微观结构分析表征。结果表明:在0.5%催化剂的投加量、pH=6的反应体系和50min的光照时间,达到最大COD去除率7.2%。

The oilfield waste-water was treated on photocatalytic oxidation by nano -particle titania and UV . the effects of pH value, amount of catalyst , time of reaction, and H2O2, Fe^3＋were investigated. The experiment analyst the catalyst by XRD and SEM . the result indicate that the best removal rate of COD was 7.2% ,when the amount of catalyst was 0. 5%,the pH value was 6 , the time of reaction was 50 minutes.
