Degradation of Refinery Wastewater by Ozonation Combined With Catalytic Technology

The efficiency of catalytic ozonation on treating refinery wastewater was investigated and a simulated activated sludge process was conducted to determine the biodegradability improvement.The experimental results show that the heterogeneous catalyst of copper loaded activated carbon combined ozonation is effective on degrading the organic pollutants and improving the biodegradability of refinery wastewater.When treating 4 000 mL wastewater,the average COD removal rate of 65.0% is attained while the BOD5/COD rate is improved from 0.13 to 0.28,under the optimal operational conditions of pH 11,ozone flow rate 40 L/h,catalyst quantity 200 cm3 and reaction time 40 min.
