| 摘 要： | 室内实验了TiO2紫外光催化氧化处理废水中的低浓度甲醇。通过对TiO2催化剂活性及添加方式、溶液pH、紫外光强与催化剂加量等参数优化,在TiO2加入浓度为300mg/L和120 W紫外灯照射条件下,对6.8L甲醇浓度为2.77%的低浓度含醇废水持续处理70min后,废水中的甲醇去除率可达98.31%。该实验为进一步处理低浓度含醇废水提供了方法依据。 |
| 关 键 词： | 低浓度含醇废水 甲醇降解 TiO2光催化氧化 |

| Abstract: | Indoor experiment for the low concentration methanol in wastewater by TiO2 UV photocatalytic oxidation was conducted.We optimized the parameters such as TiO2 catalyst activity and adding mode,solution pH,UV intensity and catalyst dosage.On the conditions of 300 mg/L TiO2 concentration and 120W UV lamp irradiation,6.8L low concentration of alcohol-containing wastewater with methanol concentration of 2.77% was degraded for 70 minutes.After the treatment,methanol concentration degradation ration reached 98.31%.The experiment provided a method for the further processing of the low concentration of methanol-containing wastewater. |
| Keywords: | low concentration of methanol-containing wastewater methanol degradation TiO2 photocatalytic oxidation |
