摘　　要：广州白云山一峰污水处理工程采用了新型污水处理工艺-多级曝气-微生物制剂强化固定生物膜处理工艺,对该工艺的特点及设计体会进行了讨论。设计进水COD、BOD5、SS、NH3-N、TP、动植物油为400～600mg/L、300～400mg/L、250～400mg/L、20～30mg/L、3～5mg/L、70～100 mg/L,出水为90mg/L、20mg/L、10mg/L、10mg/L、0.5mg/L、10 mg/L。实际运行结果表明：主要出水指标COD、BOD5、SS、NH3-N、TP、动植物油的去除率分别可达到88.1%、94.4%、97.9%、88.6%、94.6%、91.5%。该工艺具有占地少、建设成本低、结构简单、施工容易、能耗低、噪声低、运行可靠、稳定达标、剩余污泥极少、运行成本底、维护简便等优点。In Guangzhou Baiyun Mountain Yifeng Wastewater Treatment Project, the new technology for wastewater treatment of multi - stage aeration and fixed biofilm enhanced by immobilized dominant microorganisms was used. The process characteristics and the design experience were discussed. The design influent water COD, BOD, SS, NH3- N, TP , plant and animal oils are 400～600mg/L,300～400mg/L,250～400mg/L,20～30mg/L,3～5mg/L,70～100 mg/L and effluent water are 90mg/L,20mg/L,10mg/L,10mg/L,0. 5mg/L,10mg/L. It is indicated by the practical operation project that the removal rates of main effluent indexes , such as COD,BOD, SS, NH3- N,TP , plant and animal oils reached to 88. 1%, 94.4%,97. 9%,88. 6%,94.6%,91.5%, respectively. The process has the characteristics such as less land occupied, low construction cost, simple structure, easy construction, low energy cost, low noise, high reliability, reaching the standard steadily, low excess sludge production, lower cost of running and convenient management.
