摘要
采用超声辅助活性炭处理亚甲基蓝和甲基橙两种模拟染料废水。考察了活性炭用量、超声温度、超声功率、超声时间对两种染料的去除效果。研究结果表明:在亚甲基蓝和甲基橙废水初始质量浓度均为100 mg/L条件下,超声功率为60 W,超声时间为20 min,活性炭投加量为1.0 g,超声温度为80℃时,超声辅助活性炭对两种染料的处理效果最好,分别为93.46%和95.60%。数据分析发现,活性炭用量对两种染料的去除率存在极显著性差异。超声辅助活性炭处理两种染料的反应均呈现一级动力学反应特征。
The ultrasonic assisted granular activated carbon is used for the degradation of methylene blue and methyl orange . The effective factors such as the active carbon dosage ,ultrasonic temperature ,ultrasonic power and ultrasonic time on degrada-tion rate of methylene blue and methyl orange are studied .When the concentration of dyes is 100 mg/L ,ultrasonic power 60 W ,ultrasonic time 20 min ,active carbon dosage 1 .0 g and ultrasonic temperature 80 ℃ ,the degradation rate of methylene blue and methyl orange is 93 .46% and 95 .60% respectively .Theresults show there is a very significant difference between the removals of methylene blue and methyl orange by changing the active carbon dosage .The degradation data of methylene blue and methyl orange is well fitted by the first order reaction kinetics .
