Paper Title:
Study on Catalyst of Catalytic Wet Oxidation of High-concentration Industrial Organic Wastewater
  Abstract

A kind of compound catalyst containing the main activate component CuO, the second activate component ZrO2 and electronic promoter La2O3 was prepared. It was applicable to treat with high-concentration dimethyl acetylsuccinate (DMAS) production wastewater with catalytic wet air oxidation technology which was used in continuous bubble columns reactor. In this article the influences of concentration of soaked liquid of every component and the second activate component were studied, and the best preparation condition has been determined. The experimental results indicated that the catalyst of CuO-ZrO2-La2O3/ZSM-5 had a higher activity when handling high-concentration DMAS production wastewater. With this catalyst the CODcr removal rate could get 98.7% while non-catalyst only 35.8% at the reaction conditions as follows: reaction temperature 240°C, reaction pressure 3.5MPa, liquor space velocity=2.0 h-1, V (oxygen): V(wastewater)=250:1 and influent wastewater pH=7.
