臭氧活性炭联用工艺处理甲基橙废水试验研究

The experimental study of the ozone and activated carbon combined technology on methyl orange wastewater treatment

在印染废水处理中,废液浓度不同,臭氧、活性炭、臭氧—活性炭三种工艺对甲基橙的脱色效果不同。相同臭氧浓度条件下,不同浓度的甲基橙脱色率—时间曲线近似重合;活性炭在吸附饱和的情况下,能够催化空气降解甲基橙;溶液的浓度对臭氧—活性炭脱色效果有一定影响,甲基橙浓度越大,pH越高,脱色速率越大。

In printing and dyeing wastewater treatment,the decolorized effect of the waste water processing is different from three technologies of ozone,activated carbon,ozone-activated carbon,with the different concentration of the waste water.Test results show：the decolorized rate and time curves of the different concentration wastewater coincide at the same ozone concentration conditions;the methyl orange can be degraded by the catalyzed air,with the activated carbon saturated adsorption;the decolorized effect of ozone activated carbon is influenced by the concentration of the wastewater;the greater concentration of methly orange,the higher of the pH value,and the greater of the decolorized rate.
