摘要
介绍了一种改良型A2/O工艺在云南省某小型污水厂的设计及其运行情况。该厂近期工程规模为1.0×104m3/d,原水全部为生活污水,采用两点回泥、增设预缺氧池的改良A2/O工艺,出水水质可达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级B标准,且经济可行。
The design and operation of an improved A^2/O process in a small-scale wastewater treatment plant, Yunnan Province are introduced. The treatment capacity is 1.0 × 10^4 m^3/d. The raw wastewater is completely domestic sewage. The two-site sludge reflux and pre-anoxic tank are adopted in the improved A^2/O process. The effluent quality meets the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002 ）, and the process is economic and feasible.
