Optimization of Parameters for Microwave Catalytic Oxidation in Livestock Farming Wastewater Treatment
摘要
Abstract
The microwave catalytic oxidation technology was used to treat livestock farming wastewater,and the effects of five factors,namely pH,microwave time,microwave power,catalyst dos-age,and hydrogen peroxide dosage,on the COD removal rate were studied in anaerobic digesters.The Box-Behnken experimental design in response surface method was used,with COD removal rate as the re-sponse value,the microwave time,microwave power and activated carbon dosage as the influencing fac-tors,and the Box-Behnken experimental design was used to establish a mathematical model.The analysis of variance showed that the order of significance of the influencing factors was:microwave power＞activa-ted carbon dosage＞microwave time,and the interaction between microwave power and microwave time had a significant effect on the COD removal rate.The model predicted the optimal conditions,which were indicated as microwave time 14.83 min,microwave power 320 W,and activated carbon dosage 14 g·L-1.The removal rate of COD was 89.79％,the relative error between the model-predicted and the measured values was 0.54％.Microwave catalytic oxidation technology can be adopted for livestock wastewater to meet the first discharge standard of COD＜100 mg·L-1in Pollutant Emission Standards for Livestock and Poultry Farming(GB18596).关键词
