Degradation of phenol by an electrochemical heterogeneous catalytic process was applied in packed bed electrolytic reactor with graphite electrode. The catalyst was characterized by SEM and the effects of pH, the applied potential and Na2SO4 on the efficiency of the electrochemical oxidation phenol process were also studied. It was found that the optimal condition was an applied potential of 25V,...
The Catalytic Wet Oxidation (CWO) method was investigated to treat wastewater from chemical container cleaning process, which contains various and high-strength pollutants. A heterogeneous catalyst was studied with Cu2+ as the active component and activated carbon as the supporter. The effects of Cu2+ concentration, calcination temperature and calcination time on the Cu-based catalyst performance...
Active carbon-ceramic sphere as support of ruthenium catalysts were evaluated through the catalytic wet air oxidation (CWAO) of resin effluent in a packed-bed reactor. Active carbon-ceramic sphere and ruthenium catalysts were characterized by N2 adsorption, CO chemisorption and SEM measurements. BET surface area and total pore volume of active carbon(AC) in active carbon-ceramic sphere increase with...
Platinum catalysts on activated carbon (AC) were developed and examined for the removal of organic pollutants from wastewater. The Pt/AC2 catalysts were more active than the Pt/ACl and Pt/AC3. With the analysis of BET, XPS and SEM, it was found that the quantities of oxygen containing groups on the AC surface increased after AC supports were pre-treated by oxidant, and farther the dispersion of Pt...
Characteristics of cells proliferation and substrate transfer of immobilized nitrifiers during cultivation was investigated. The respiratory rate, nitrification rate and biomass in the pellets showed a similar tendency of slow increase when cultivation was over. The activity of unit biomass decreased for the difficult oxygen transfer into the compact microcolonies. De also went degressive gradually...
