【摘要】 根据麦芽生产废水的特点,采用水解酸化/活性污泥/气浮为主体的废水处理工艺,设计并建成了麦芽废水处理站。工程运行结果表明,在进水COD、BOD5和SS分别为(401～832)、(128.2～240.2)和(88～258)mg/L的情况下,出水COD为36～60 mg/L、BOD5为10.2～14.6mg/L、SS为32～50 mg/L,达到了《啤酒工业水污染物排放标准》(GB 19821—2005),处理成本为1.17元/m3。实践证明,采用水解酸化/活性污泥/气浮工艺处理麦芽生产废水经济有效,为麦芽废水处理工程的设计和运行提供了成功经验。更多还原

【Abstract】 According to the characteristics of malt production wastewater,the malt wastewater treatment station was designed and built,using hydrolysis acidification/activated sludge/air flotation as the main wastewater treatment processes.The engineering operation results show that when the influent COD,BOD5 and SS are 401 to 832 mg/L,128.2 to 240.2 mg/L and 88 to 258 mg/L respectively,the effluent COD,BOD5 and SS are 36 to 60 mg/L,10.2 to 14.6 mg/L and 32 to 50 mg/L respectively,meeting the Discharge Standard of Pollutants for Beer Industry(GB 19821-2005).The wastewater treatment cost is 1.17 yuan/m3.The practice proves that hydrolysis acidification/activated sludge/air flotation process is an economical and effective method for malt wastewater treatment,which provides a successful experience for the future design and operation of malt wastewater treatment projects.更多还原
