1、摘要针对印染废水的水质特点，本文采用水解酸化与接触氧化相结合的生化工艺对废水进行处理。水解酸化和好氧接触设计停留吋间均为10h,运行结果表明，水解酸化单元可冇效捉高废水的可生化性，废水经水解酸化后B/C值可从0.2〜0.3提高至0.4左右，有效保证了好氧接触处理效果。根据环保监测结果，COD一般在80mg/L,BOD,在10mg/L以下，COD去除率80%以上，BOD,去除率90%以上。废水处理厂设计规模3500m7d,其现今的设计水质水量为Q=5000m7dCOD二1320mg/LB0D5=600mg/LPH=10SS二340mg/L色度
2、100倍。经处理后，应达到下列出水水质：CODW100mg/L,B0DW25mg/L,色度W40倍，pH在6〜9,SSW70mg/L,达污水排放一级标准。关键词：纺织印染废水，水解酸化,生物接触氧化AbstractAimingatthecharacteristicsofprintinganddyeingwastewater,abiochemicaltcchnologicalprocessofhydrolyticacidificationintegratingcontactoxidationwasappliedtotreatmentofthe
