Influence Factors of Landfill Leachate Treatment with CWAO Method

Abstract:

Landfill Leachate is a kind of organic wastewater with high concentration and non-biochemical character, and Catalytic Wet Air Oxidation (CWAO) is suitable for this kind of wastewater treatment. In this study, Landfill leachate was treated with Catalytic Wet Air Oxidation (CWAO) method. The monitoring indicators consist of COD_Cr, absorbance, pH and chroma. The results show that: COD_Cr removal rate and decolorization rate of landfill leachate reduce with the reduction of the influent pH, the increment of water concentration and the extension of the reaction time; Under the optimized operating conditions: the influent pH of 8.10, the influent COD_Cr of 16611 mg/L, the reaction time of 90 min, the COD_Cr removal rate and decolorization rate of landfill leachate reach 56.8% and 83.7%, respectively. The effluent pH is 8.33 and chroma is 1600 times.
