摘要
通过实验,研究分析了不同催化剂(TiO_2、ZnO)、pH值、光照时间对垃圾渗滤液光催化氧化的影响,得出:TiO_2光催化氧化效果明显优于ZnO的效果,TiO_2光催化氧化对COD的去除率为72％;pH值对光催化影响不大,pH=5～9均可;光照时间60min效果最好。
Through experiment, the effects of different catalysis such as TiO2 and ZnO2 pHand reaction time on the landfill leachate treatment are explored and analyzed. The result shows that the photo - catalytic effects of TiO2 are superior to that of ZnO and the oxidization removal rate of TiO2 can come up to 72 % , that the effects of pH are unobvious with the range from 5 to 9 and that the reaction time of 60 minute can reach optimun effect.
