Abstract :
In this article, removal efficiencies of BOD and COD of landfill leachate was investigated using supercritical water oxidation (SCWO) process. Under different circumstances -high pressure, high temperature, wet air oxidation (WAO), sub-critical water and SCWO- experimental results were obtained. Organic compounds were almost completely removed when the pressure was above 30 Mpa, and temperature was above 400degC. The results indicate that organic compounds removal efficiencies increase with the increasing of the temperature. Nevertheless, the organic compounds removal efficiencies almost have nothing to do with the pressure of this system at the temperature below 300degC. When the temperature is higher than 300degC, the pressure of the system influenced the COD removal to some degrees.
