红枫发电厂生活污水处理站升级改造规模为500m3/d,在原简易DAT—IAT工艺的基础上进行升级改造。介绍了原污水处理系统存在的问题、工艺改造的内容、改造后的运行效果等。经过技术改造后,解决了原处理系统无污泥回流、排水设施、污泥淤积等问题,出水水质达《污水综合排放标准》(GB8978-1996)表2第二类污染物最高允许排放浓度中的一级标准和《城市污水再生利用——城市杂用水》(GB/T18920-2002)表1中水质标准。

The design capacity of upgrading and retrofitting project of Hongfeng power plant is 500m3/d, upgra- ding based on the original simple DAT - IAT process. Introduced the existing problems, the original sewage treat- ment system transformation content, operating effect after reformation etc.. After the technical reconstruction, the problem of processing system without sludge reflux, drainage facilities, sewage sludge sedimentation, effluent water quality meet the ＂integrated wastewater discharge standard＂ （GB8978 - 1996） table 2 second pollutants in the maximum allowable level standard of ＂discharge concentration and wastewater reuse of city - - city of miscellaneous water＂ （ GB/T18920 -2002） surface water quality standard1.
