摘要
Abstract
Coking wastewater was treated by catalytic supercritical water oxidation process. The experimental results show that: The removal rate of NH,-N in the wastewater can be increased by increasing the reaction temperature and the reaction pressure or extending the reaction time; Under the optimum conditions of reaction time 60 s, reaction pressure 30 MPa and reaction temperature 460 ℃, the NH3-N removal rate without catalyst is 53.7%; With the addition of catalyst MnO2 or CuSO4, the NH3-N removal rate is increased greatly, which is 86.9% and 92.4% respectively.关键词
