摘　　要：针对文登市污水处理厂Orbal氧化沟工艺出水水质不能满足一级A排放标准的问题,先后采用多级AO工艺和A^2O工艺对Orbal氧化沟进行改造。运行结果显示,多级AO工艺改造方案对污染物的去除效果有所提高,有很好的节能效果,同时有一定的污泥减量作用;A^2O工艺改造方案对污染物有较好的去除效果,且改造实施简单,处理效果较稳定,运行管理方便,确定为最终的工程改造方案。两种改造方案可为我国类似Orbal氧化沟工艺的升级改造提供参考。The effluent of the Orbal oxidation ditch process in Wendeng WWTP could not meet the first level A of the discharge standard. Multistage AO process and A2O proeess were utilized to transform the Orbal oxidation diteh. The operational results showed that the multistage AO process retrofit scheme improved the removal effieieney of pollutants, and demonstrated desirable energy efficiency and sludge reduction effect as well. The A2O proeess retrofit scheme exhibited favorable treatment effeet, in addition to advantages such as simplieity in implementation, stability in treatment effect, and eonvenienee in opera- tion and management. The A2O process scheme was confirmed for engineering retrofit. The two retrofit schemes provided references for upgrading of similar Orbal oxidation ditch processes in China.
