摘要
以粉末活性炭为催化剂,建立了微波协同氧化工艺,对模拟甲基橙废水进行处理。微波协同氧化、活性炭吸附和单纯微波辐射3种不同工艺的对比实验表明,微波诱导氧化工艺具有明显的优越性.考察了甲基橙浓度、微波功率、辐射时间、活性炭用量对甲基橙去除率的影响。在甲基橙质量浓度为305mg/L、微波功率580W、辐射时间10min、活性炭用量1.2g/L的条件下,甲基橙色度去除率为99.63%,COD的去除率为95.8%。
A microwave technique assisted with dusty active carbon was used for the degradation of methyl orange wastewater. The contrast experiment of three different techniques, which are the microwave assisted with active carbon, active carbon absorption and sole microwave irradiation, indicated that the microwave assisted with active carbon had obvious advantage. The effective factors such as the concentration of methyl orange, microwave power, irradiation time, active carbon dosage on the degradation rate were studied, When the concentration of methyl orange was 305 mg/L, irradiation time was 10 min, active carbon dosage was 1.2 g/L and microwave power was 580 W, the degradation rate of chroma was 99.63% and the degradation rate of COD was 95.8%.
