摘要
以西安市氧化沟污水处理厂和A^2O+MBR污水处理厂为例,从处理原理、工艺流程以及运行效果三方面对比分析氧化沟工艺和A^2O+MBR工艺,对两个厂的出水水质进行了为期一年的跟踪监测,检测结果表明:出水COD,TP,TN,NH_3-N浓度均优于GB 18918—2002城镇污水污染物排放标准中的一级A排放标准;A^2O+MBR工艺对COD,TP,NH_3-N的去除效果优于氧化沟工艺;氧化沟工艺对TN的去除效果优于A^2O+MBR工艺。
This paper takes Xi’an oxidation ditch sewage treatment plant and A^2O＋MBR sewage treatment plant as an example.The oxidation ditch process and A^2O＋MBR process are compared and analyzed from three aspects of the treatment principle,technological process and operation effect,and the effluent quality of the above two plants was monitored for one year.The concentrations of COD,TP,TN,NH_3-N in the enfluent were better than the first level A criteria specified in the Discharge Standard of Pollatants for Municipal Wastwater Treatment Plant（GB 18918—2002）,the removal efficiency of COD,TP and NH_3-N by A^2O＋MBR process is better than that of oxidation ditch process,the removal efficiency of TN by oxidation ditch process is better than that of A^2O＋MBR process.
