摘　　要：蚌埠杨台子污水处理厂二期工程采用预处理-A^2O微曝氧化沟-深床滤池-紫外线消毒组合工艺处理城市污水,采用机械浓缩脱水工艺处理污泥。工程运行结果表明,在进水ρ(CODCr)=231.0~321.0 mg/L,ρ(BOD5)=85.0~142.0 mg/L,ρ(SS)=74.0~154.0 mg/L,ρ(NH3-N)=26.5~33.9 mg/L,ρ(TN)=28.9~35.6 mg/L,ρ(TP)=1.80~2.90 mg/L的情况下,出水水质指标达到或优于GB 18918—2002《城镇污水处理厂污染物排放标准》中一级A标准。介绍了工艺流程、主要处理构筑物工艺设计参数、设备性能参数,分析了工艺设计特点,简述了运行效果。In the second-phase project of Bengbu Yangtaizi sewage treatment plant, municipal sewage was treated by pretreatment-A^2O micro aeration oxidation ditch-deep bed filter-ultraviolet disinfection combined process, and sludge was treated by mechanical concentrated dehydration process. The operation results of the project showed that, when the mass concentrations of CODc, BODs, SS, NH3-N TN and TP in the influent water were 231.0 - 321.0, 85.0 - 142.0, 74.0 - 154.0, 26.5 - 33.9, 28.9 - 35.6 and 1.80 - 2.90 mg/L respectively, the effluent water quality reached or superior to the requirement of level A grade 1 in GB 18918-2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant. The process flow, design parameters of main structures, and performance parameters of equipments were introduced; besides, the design characteristics of the process were analyzed with the operation effect described briefly.
