摘　　要：化纤聚合(锦纶)废水浓度高,处理难度大,费用高,采用“化学催化氧化+升流式厌氧污泥床”处理,可将具有毒性、抑制性的高分子苯环有机物降解为小分子易生化有机物,再通过序批式活性污泥法进行处理,出水化学需氧量<50mg/L,达到《污水综合排放标准》(GB8978—1996)中的一级排放标准。The high-concentration chemical fiber polymerization(nylon)wastewater is difficult to be treated,and the treatment is costly.The adoption of"chemical catalytic oxidation+upflow anaerobic sludge bed(UASB)"for treatment can degrade the toxic and inhibitory high molecular weight organic matters with benzene ring into biodegradable low molecular weight organic matters.After that,the treated wastewater can be treated through the SBR(sequencing batch reactor activated sludge process)tank.The chemical oxygen demand(COD)in effluent was<5Omg/L,meeting the first grade discharge standard of Comprehensive Sewage Discharge Standard(GB 8978-1996).
