摘　　要：青海省某污水处理厂二期扩容提标改造工程,采用改良AAO及机械絮凝斜管沉淀池/转盘滤池深度处理工艺。设计新建初沉池、生物池、二沉池等二级处理构筑物,以及机械絮凝斜管沉淀池、转盘滤池、接触消毒池等深度处理车间。原一期工程建成后,厂内剩余建设用地面积较小,故设计采用组合式处理构筑物,将所有新建构筑物组合成为二级处理构筑物和深度处理车间两个单元,有效减少了占地面积和水头损失。实际运行效果良好,出水水质达到了一级A排放标准。Modified AAO and mechanical flocculation sedimentation tank/rotary disk filter were used in the second-phase upgrading project of a WWTP in Qinghai Province. Secondary wastewater treat- ment process contained primary sedimentation tank, AAO biological reactor and secondary sedimentation tank. Advanced treatment process is composed of mechanical flocculating tube settler, disc filter and con- tact disinfection tank. After the first-phase of the WWTP was completed, available area is difficult to meet the requirement of second-phase process structure in the conventional design. The application of combination designed of wastewater treatment structure reduced the footprint and head loss. The actual op- eration showed that the treatment system runned well. The effluent quality met the first class A standard.
