| 摘 要： | 用活性炭吸附、二氧化钛光催化降解处理酸性红G染色废水．用正交试验法研究了活性炭用量、吸附时间、二氧化钛用量、紫外灯照射时间对酸性红G去除率的影响．结果表明：若使用活性炭吸附，在20mL浓度为5．26×10^-5mol／L的废水中加0．8g活性炭，搅拌30min，废水中酸性红G去除率达97．1％．若用二氧化钛光催化降解，则在20mL相同浓度的废水中加二氧化钛0．05g，在300W紫外灯下照20min，废水中酸性红G去除率为99．2％．

| Abstract: | Acid Red G dyeing wastewater was treated by active carbon adsorption and photocatalytic degradation using TiO2 under ultraviolet irradiation. The influences of active carbon dosage, the adsorption time, TiO2 dosage and the irradiation time on the removal ratio of Acid Red G from the its dyeing wastewater were investigated. The results showed that 97.1% of the Acid Red G in 20mL 5.26 × 10 ^-5 mol/L wastewater could be removed after adding 0.8g active carbon and stirring for 30min. While using photocatalytic degradation method, 99.2% Acid red G in the wastewater with the same concentration can be degradated under the condition of adding 0.05g TiO2 and irradiating for 20min with stirring. |
