摘　　要：结合工程实例,本文对优势微生物强化水解—多级接触氧化处理屠宰废水工艺及设计体会进行了讨论。设计进水COD、BOD5、SS、NH3-N、动植物油为2300-2700mg/L、900-1300mg/L、600-800mg/L、100-120mg/L、70-90mg/L,出水为90mg/L、20mg/L、60mg/L1、0mg/L1、0 mg/L。实际运行结果表明：主要出水指标COD、BOD5、SS、NH3-N、动植物油的去除率分别可达到97.9%、98.6%、93.7%、93.4%、90.7%。该工艺具有占地少、建设成本低、运行可靠、稳定达标、剩余污泥少、运行成本低、维护简便等优点。Process of hydrolysis-multi-stage biological contact oxidation enhanced by dominant microorganism for the treatment of slaughter waste water and the design experience were discussed.The designed influent water COD,BOD,SS,NH3-N,plant and animal oils are 2300～2700mg/L,900～1300mg/L,600～800mg/L,100～120mg/L,70～90mg/L and effluent water are 90mg/L,20mg/L,60mg/L,10mg/L,10 mg/L,respectively.It is indicated by the practical operation project that the removal rates of main effluent indexes,such as COD,BOD,SS,NH3-N,plant and animal oils reached to 97.9%、98.6%、93.7%、93.4%、90.7%,respectively.The process has the characteristics of less land occupied,low construction cost,high reliability,reaching the standard steadily,low excess sludge production,low running cost,convenient management.
