摘　　要：中南地区某水源保护地一批乡镇污水处理厂现状出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级B标准,改造后执行一级A标准。结合此次升级改造工程设计经历,总结了乡镇污水处理厂升级改造工程的实施难点和设计原则。介绍了传统AAO工艺、改良AO工艺、MBR工艺和MBBR工艺4种技术路线,为此类工程的开展提供了可靠的思路。Some township wastewater treatment plants( WWTPs) in a conservation area of water supply, locating in South Central China,were upgraded from the first class B criteria to A criteria. According to thepractice in engineering design, difficulties in implementation and principles in design were summarized.Four kinds of upgrading process were introduced, including conventional anaerobic anoxic oxic process (AAO), modified anoxic oxic process (AO), membrane bioreactor process(MBR) and moving bed biofilm reactor process(MBBR). Reliable schemes were provided for these similar upgrading projects in this paper.
