摘要
兰州雁儿湾污水处理厂一线提标改造工程规模为2×10 4m3/d,在满足原位提标、池壁不增加负载、强化脱氮能力的需求下,采用MABR工艺实现出水水质提升至《城镇污水处理厂污染物排放标准》(GB 18918-2002)的一级A标准.该工程主要通过MABR膜箱进行新生化区域叠加设计与原生化功能区重组,强化生化处理效能.作为国内首例万吨级MABR市政污水提标改造项目,无需新增土建和停水施工.为期一年的监测表明,在未投加碳源条件下,改造后出水水质稳定满足一级A标准,出水TN平均仅为8.21 mg/L,运行成本降低约0.103元/m3,节省运行费用约75万元/a.
Abstract
The line 1 upgrading project of the Yanerwan wastewater treatment plant(WWTP)in Lanzhou encompasses a scale of 2×10 4 m3/d.Adhering to the imperatives of in-situ upgrading,non-augmentation of pool wall loads,and reinforced denitrification capabilities,the membrane-aerated biofilm reactor(MABR)process is adopted to improve the effluent quality to the first level A criteria in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).The project primarily involved overlaying design of new biofilm areas using MABR membrane modules and reorganization of indigenous functional zones to strengthen biochemical treatment efficacy.As the first 10 000 m3/d MABR municipal wastewater upgrading project in China,this project required no civil construction and water cessation.One year of monitoring revealed that the effluent quality post-upgrade met the level A standard,with an average TN concentration of 8.21 mg/L,without additional carbon source.Additionally,operational costs decreased by approximately 0.103 yuan/m3,saving operation cost of about 750 000 yuan/a.
