摘　　要：介绍了含酸性蒽醌蓝324染料废水在兼氧-好氧系统中的生物转化。产物分析结果表明:80.5%的母体染料大分子能在兼氧条件下降解成较为简单的中间产物,并且这些中间产物能在好氧条件下进一步矿化。对各反应器中主要的代谢产物分别进行紫外-可见、红外(FT-IR)和高效液相色-质联谱仪(HPLC-MS)检测分析后发现,母体染料经兼氧水解首先生成1-氨基-2-羟基蒽醌以及还原态的—OH基取代蒽醌隐色体,进一步水解生成3,4-二羟基苯甲酸。再经好氧处理,降解终产物中检测到了质荷比为101、102的脂肪类碳氢化合物、胺及醇等物质,未见有共轭结构存在。The transformation of an anthraquinon dye blue 324 in a facuhative-aerobic system was investigated. Results of the product analyses indicated that most of dye molecules could be facuhatively broken down into simple intermediates, which would be further degraded under subsequent aerobic condition. The main metabolites in each reactor were detected by UV/VIS, infrared （FT-IR） and high performance liquid chromatography and mass spectrometry （HPLC-MS）. Probably, the mother dye molecule facuhatively hydrolyzed to produce 1- NH2-2-hydroxy anthraquinon, OH-substituted anthraquinon and 3,4-dihydroxy-benzonic acid. The hexahydrate and its derivatives were obtained after aerobic process. Non-conjugated structures were found in the final products.
