摘　　要：本论文针对糖厂的混和废水处理问题,采用水解酸化-SBR工艺对混和废水进行处理,经中试运行结果表明:当水力停留时间(HRT)为4h,进水废水化学需氧量(COD)为1000mg/L时,首先利用水解酸化工艺处理则混合废水的COD去除率可达到25%;然后经循环周期为8h的序批式活性污泥法(SBR)处理能保证COD去除率达到90%。混和废水经本试验设计的工艺处理后可以达到污水综合排放标准。The mixed wastewater of sugar refinery was treated using the hydrolysis acidification-SBR process.The pilot-scale experiment showed that,when hydraulic detention time（HRT） was 4 hour and chemical oxygen demand（COD） of Influent water was 1000 mg/L,the COD of effluent wastewater decreased 25% using the hydrolysis-acidification.After the 8 hour processing of Sequencing batch reactor（SBR）,the COD of effluent wastewater decreased to 90%.After this processing,the indexes of mixed wastewater can reach the standards of integrated wastewater discharge.
