【摘要】 对垃圾渗滤液中大量存在的有机酸——正丁酸进行了Mn-Ce复合氧化物催化剂催化湿式氧化降解的研究,并采用统计回归分析法建立了Mn-Ce催化剂催化湿式氧化降解正丁酸升温和恒温过程的降解模型。回归方程的残差分析结果表明,Mn-Ce催化剂催化湿式氧化降解正丁酸升温和恒温过程的降解模型计算值与实验值吻合良好;此外,回归方程的决定系数(R2)以及Nash-Suttcliffe模拟效率系数(NSC)均达到0.80以上,表明模型预测准确度较高。更多还原

【Abstract】 In this paper,the n-butyric acid that abounds in landfill leachate was used to be degraded over Mn/Ce catalyst by catalytic wet air oxidation,and the models that the heating and constant temperature reaction process of n-butyric acid degradation were established by statistical regression analysis method.The residual results of the regression equations show that the values calculated from the two models are well agreed with the experimental data.The coefficient of determination(R2) and Nash-Suttcliffe coefficient(NSC) of the prediction models for heating and reaction processes are both more than 0.80,indicating that the two models predict well.更多还原
