一体化氧化沟工艺是一种新型的生活污水处理技术。该工艺集曝气、沉淀、泥水分离和污泥回流功能为一体，减少占地面积，该装置有结构紧凑、运行操作简便的优点。经过中原油田近1a的试运行调试和监测，结果表明，该装置处理效果不断提高，至稳定运行时，COD的去除率为91%、BOD5的去除率为92%、NH3-N的去除率为96%、SS的去除率为91%。

The integrative oxidation ditch process is a new technology for domestic sewage disposal. The process integrate aerated oxygen, precipitation, sludge separation and sludge reflux functions. It reduces the area of land occupation. The unit is characterized by compact configuration and simple operation. After application and detection for 9 months, The result shows that through the application of integrative oxidation ditch process to Zhongyuan Oilfield Sewage Treatment Plant, the removal rates of COD, BOD 5, NH₃-N and SS reach 91%, 92%, 96% and 91% resprctively.
