摘要:
湖南某污水处理厂提标扩建工程，对一期氧化沟工艺进行改造，二期扩建采用改良AAO池+二沉池+高效沉淀池+精密过滤器+联合消毒工艺，加强脱氮除磷。提标扩建后总规模达到4.0×104 m3/d，出水水质由《城镇污水处理厂污染物排放标准》（GB 18918—2002）的一级B标准稳定提升到一级A标准，且出水COD达到《湖南省城镇污水处理厂主要水污染物排放标准》（DB 43/T 1546—2018）的二级标准。
Abstract:
The first-phase project need to be upgraded, and the combined process of modified AAO tanks, secondary clarifier, high-efficiency sedimentation tank, precision filter, and joint disinfection was applied to the second-phase extension project of a WWTP in Hunan to strengthen nitrogen and phosphorous removal. The total capability after extension was 40 000 m3/d. The effluent quality was steadily upgraded from the first level B to the level A criteria of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), and the effluent COD met the second level criteria of Discharge Standard of Major Pollutants for Municipal Wastewater Treatment Plant(DB 43/T 1546-2018).
