摘　　要：将多相光催化氧化法与生物氧化法组合 ,探讨两种组合技术在太阳光条件下利用负载型催化剂降解染料化合物的可行性 .实验选用 5 0 ppm的活性艳红K 2G为典型实验溶液 ,并在一定条件下加生活污水 .生化单元经 2 4h生物氧化 ,对溶液COD的去除最高可达 82 .92 % ;光氧化单元经 5h光催化反应 ,对色度的去除也能保持在 2 0 %— 30 %之间 .实验结果表明 。The feasibility of the combination technique of photocatalytic oxidation with biochemical oxidation for dye degradation under the condition of the sun light and the fixed TiO 2 was studied. The results showed that the combination technique worked very well. For example, a 50ppm Brilliant Red K 2G solution, the COD removal were 82.92% in 24 hours biological treatment. Consequently, after 5hours photocatalytic oxidation, the color removal was 20%—30%. It might be an effective method to degrade the dye.
