Study on Change of Suspended Matter Concentration During Treatment of Landfill Leachate With CWO Method

LIN Wan-rou,CAI Miao-ling,CAI Wu-jian,CAI Xiang-nan(Department of Chemistry,Hanshan Normal University,Guangdong Chaozhou 521041,China)  
Treatment effect of different catalysts for landfill leachate by catalytic wet oxidation degradation was studied.High-effective catalyst was screened out by measuring changes of suspended matter removal rate.Through comparing influence of reaction conditions on suspended mater removal rate,the best reaction conditions were gained as follows:catalyst dosage 0.372 g,metal ion concentration 300 mg/L,reaction temperature 180 ℃,oxygen partial pressure 3.5 MPa,pH value of water 8.10,stirspeed 500 r/min.
