摘　　要：随着资水流域环保要求的提高,污水处理厂的排放标准也显著提高。本文以湖南某污水处理厂提标至一级A标准为例,对项目的工程背景、实际运行情况、提标改造方案、设计参数和运行效果等进行介绍。通过对原有改良型氧化沟改造优化,以及新增"高效沉淀+纤维转盘滤池"的深度处理工艺,提标后污水处理厂出水指标稳定达到《城镇污水厂污染物排放标准》(GB18918-2002)中一级A排放标准。with the improvement of environmental protection requirements in Zishui River Basin, the discharge standard of sewage treatment plant is significantly improved. Taking a sewage treatment plant in Hunan Province as an example, this paper introduces the engineering background, actual operation, upgrading and reconstruction scheme, design parameters and operation effect of the project. Through the transformation of the original improved oxidation ditch and the new advanced treatment process of "high-density clarification + fiber rotary filter", all indicators meet the class a discharge standard in the discharge standard of pollutants for urban sewage treatment plant(GB18918-2002).
