MBR工艺在神定河污水处理厂升级改造工程中的应用
|
摘要
十堰神定河污水处理厂升级改造工程设计总规模为18×10~4m~3/d,其中一期工程仍沿用A/O+二沉池工艺,设计规模由原5. 5×10~4m~3/d降负荷调整为4×10~4m~3/d,出水水质需达到一级B排放标准;二期工程采用AAO+MBR工艺,设计规模由原11×10~4m~3/d扩容到14×10~4m~3/d,出水水质执行一级A排放标准。两期工程的混合出水水质需达到一级A排放标准。投产运行后,出水水质优于设计标准。
The design treatment capacity of the upgrading and reconstruction project of Shending River Wastewater Treatment Plant was 18 × 10~4 m~3/d. In the first-stage project,A/O + secondary sedimentation tank process was adopted and the treatment capacity was reduced from 5. 5 × 10~4 m~3/d to 4 ×10~4 m~3/d. The effluent quality of the first-stage project was required to be better than the first class B discharge standard. The design capacity of second-stage project was increased from 11 × 10~4 m~3/d to 14 ×10~4 m~3/d,and AAO + MBR process was adopted as the treatment technology. The effluent quality of the second-stage project should meet the first class A discharge standard. The mixed effluent of the two projects should reach the first class A discharge standard. In the period of operation,the effluent quality was proven to be better than design discharge standard.
