摘要:
成都某城市生活污水处理厂处理规模为4×104 m?/d，需将污水排放标准由原一级A标准提高至《四川省岷江、沱江流域水污染物排放标准》（DB 51/2311—2016）中城镇污水处理厂排放标准（地表水准Ⅳ类水质标准）。通过分析原工艺系统存在的脱氮能力不足、碳源投加量大、氧化沟流速不均、污泥易沉积等问题，提标改造工程将原A2/C氧化沟工艺原位改造为五段Bardenpho工艺，并新增高效沉淀池+脱碳生物滤池组合深度处理工艺。改造完成后出水水质优于地表水准Ⅳ类标准，提标改造工程总投资为10 012.24 万元，运行成本为0.404 元/m3。
Abstract:
The treatment scale of a wastewater treatment plant (WWTP) in Chengdu is 4×104 m?/d, and the discharge standard needs to be upgraded from the first level A standard to Water Pollutant Discharge Standard for Minjiang River and Tuojiang River Basin in Sichuan Province (DB 51/2311-2016, quasi-Ⅳ surface water limit). The problems existing in the original process were analyzed, which included insufficient nitrogen removal capacity, large amount of carbon source dosage, uneven flow rate of the oxidation ditch and easy deposition of the sludge. The upgrading project transformed the original A2/C oxidation ditch process into a five-stage Bardenpho process in situ, and an advanced treatment process consisting of a high efficient sedimentation tank and a decarburization biological filter was newly-built. After the reconstruction, the effluent quality is better than that of the quasi-Ⅳ surface water limit. The total investment of the upgrading and reconstruction project is 10.012 24 million yuan, and the operating cost is 0.404 yuan/m3.
