摘要
介绍了西安市第二污水处理厂升级改造工程的工艺流程和构筑物设计。工程设计中充分考虑利用原有工程场地,新建多段多级AO池+终沉池,与原有厌氧池+DE氧化沟工艺并行处理污水,总处理量为15×10~4m^3/d。实际运行表明,工程运行效果良好,出水水质达到了《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。
The process flow and the structure design of the upgrading and reconstruction project of Second WWTP in Xi' an City were introduced. Based on the full use of existing site, the new multistage AO tank and final settling tank were constructed to treat the wastewater along with the original anaerobic tank and DE oxidation ditch. The total treatment capacity was 15 ~ 104 ma/d. The actual operation showed that the treatment effect was good, and the effluent quality could meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918 - 2002).
