摘　　要：采用减压蒸馏耦合固定化微生物法处理TNT红水．利用GC—MS对TNT红水和馏分的有机组分进行分析．结果表明，TNT红水的有机组分主要有1，4-二硝基苯、4-甲基苯酚、2-甲基苯酚等：馏分的有机组分主要有4-甲基苯酚、苯酚、2-甲基苯酚、2，4二硝基甲苯、1,4-二硝基苯等．馏分采用以FPUFS为填料的固定化微生物-生物滤池进行处理．经处理后．硝基化合物浓度为0-1．6mg／L、COD为50-90mg／L，符合TNT废水排放标准．TNT red water was treated by vacuum distillation coupling in immobilized microorganism. Organic components of TNT red water and distillate were analyzed by gas chromatography-mass spectrometry（GC-MS）. The main organic components of TNT red water were 1,4-dinitrobenzen, 4-methylphenol, 2-methylphenol and so on. The distillate was composed of 4-methylphenol, phenol, 2-methylphenol, 2,4-dinitrotoluene, 1,4-dinitrobenzen and some other organic compounds. The distillate was treated by combined process of immobilized microorganism-biological filter, which used FPUFS carrier as fillings. The nitro-compounds and COD in treated distillate were 0-1.6 mg/L and 50mg/L-90mg/L, respectively, which met wastewater discharge standard for TNT.
