%X 针对四川省在岷江、沱江流域实施水污染物排放标准的要求，总结了城镇污水处理厂提标改造的主要内容和技术指标以及经济分析。介绍四川某城镇污水处理厂提标改造方案，通过部分利旧、升级改造及新增工艺段的方式，将出水标准由《城镇污水处理厂污染物排放标准》(GB18918-2002)中的一级A标提升至《四川省岷江、沱江流域水污染物排放标准》中城镇污水处理厂排放标准。提标改造工艺的建设投入成本较低，改造过程实施较快，后期管理便捷。提标改造完成后系统稳定运行，出水中主要污染物COD<sub>cr</sub>、BOD<sub>5</sub>、NH<sub>3</sub>-N、TN和TP基本稳定达到岷沱江标准的排放限值要求，取得了较好的生态环境效益。<br />
To meet the discharge standard of water pollutants in Minjiang and Tuojiang basins, the main steps for upgrading projects of domestic sewage treatment plants and several applied techniques were genera-lized as well as economic and technical analysis. An upgrading project of a full-scale domestic sewage treatment plant located in Sichuan Province was introduced. Through utilizing and upgrading current equipments and adding new processes, the effluent water quality increased from first class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) to domestic sewage treatment plant discharge standard of Discharge Standard of Water Pollutants in Min River and Tuo River Basins of Sichuan Province. The cost of this up-grading project is relatively low and it is also convenient to build and operate. The main pollution factors of COD<sub>cr</sub>, BOD<sub>5</sub>, NH<sub>3</sub>-N, TN and TP can meet designed effluent standard requirements, thus providing good ecological and environmental benefits.
