微波/活性炭/双氧水协同降解甲基红废水的研究

Study on synergetic degradation of methyl red wastewater by microwave/active carbon/H_2O_2

对微波/活性炭/双氧水联合降解甲基红染料废水进行了研究。考察了活性炭量、双氧水量、甲基红初始浓度、微波功率、pH以及处理时间等因素对甲基红降解效果的影响。结果表明,对于100 mL100 mg/L甲基红溶液,当加入0.5 g活性炭,1 mL30%H2O2,调节微波功率至680 W,反应25 min后,甲基红降解率达到81.87%。通过对比试验,发现微波、活性炭及双氧水对甲基红的降解起协同作用。

The degradation of methyl red wastewater by microwave/active carbon/H2O2 was studied. The effects of active carbon mass, H2O2 volume, initial methyl red concentration, pH and reaction time on the degradation of methyl red were investigated. The results indicated that the degradation rate of 100 mg/L methyl red wastewater got to 81.87% within 25 minutes when the active carbon mass was 0.5 g,1 mL 30% H2O2 was added and microwave power was 680 W. It is known from the contrast experiments that the methyl red was degraded by the synergetic effects of microwave, active carbon and H2O2.
