【Abstract】 Effects of initial TOC of butyric acid,catalyst dosage,reaction temperature,and initial oxygen pressure on the degradation reaction process of butyric acid under catalytic wet air oxidation were investigated,and a BP artificial neural network model for the degradation process of butyric acid under catalytic wet air oxidation was established.The simulated efficiency factor of the model was calculated to be 0.973 2(more than 0.80),indicating the model established could well and truly forecast the residual butyric acid in the degradation reaction process of catalytic wet air oxidation.Meanwhile,the reaction condition optimization of butyric acid under catalytic wet air oxidation based on the BP artificial neural network model was carried out,and the results show that the degradation efficiency of butyric acid under catalytic wet air oxidation was nearly enhanced by 20%.更多还原
