Biodegradation of a monoazo dye - Acid Orange 7 (AO7) was investigated by using an internal circulation baffled biofilm reactor. For accelerating AO7 biodegradation, endogenous electron donors produced from AO7 by UV photolysis were added into the reactor. The result shows that AO7 removal rate can be accelerated by using its endogenous electron donors, such as sulfanilic and aniline. When initial AO7 concentration was 13.6mg/L, electron donors generated by 8h UV photolysis were added into the same system. The biodegradation rate 0.4mgh was enhanced 60% than that without adding electron donor. Furthermore, sulfanilic and aniline were found to be the main endogenous electron carriers, which could accelerate the steps of the azo dye biodegradation.
采用内循环挡板式生物膜反应器研究了单偶氮染料-酸性橙 7（AO7）的生物降解。为了加速 AO7 的生物降解，向反应器中添加了由 UV 光解产生的 AO7 内源性电子供体。结果表明，可利用 AO7 的内源性电子供体，如磺胺和苯胺来加速 AO7 的去除。当初始 AO7 浓度为 13.6mg/L 时，将 8hUV 光解产生的电子供体添加到相同的系统中。生物降解速率 0.4mgh 比不添加电子供体时提高了 60%。此外，发现磺胺和苯胺是主要的内源性电子载体，可加速偶氮染料生物降解的步骤。
