| Abstract: | The combined process,coagulation air flotation-ozone oxidation/activated carbon adsorption,has been applied to the advanced treatment of chemical outward-discharged wastewater from Lanzhou Petrochemical Co.The main operation parameters are investigated and its optimal processing conditions are ascertained.The experimental results show that 50%-80% of the COD can be removed from the chemical outward-discharged wastewater whose COD was 60-100 mg/L.Its effluent COD is≤35 mg/L,steadily reaching the first class of Integrated Wastewater Discharge Standard(GB/T 8978—1996). |
