通过提标改造和扩建,某污水处理厂的处理能力从2.5×10~4m~3/d提高至5.0×10~4m~3/d,出水水质由一级B标准提高至一级A标准.通过将常规A~2/O工艺改造为倒置A~2/O工艺、优化工艺运行、局部改造和增加深度处理设施等措施,对BOD_5、SS、NH_3-N和TP的去除率分别达到95.0%、96.2%、82.1%和90.4%,出水水质达到一级A标准.详细介绍了提标改造内容及采取的措施,可为类似工程的设计提供参考.
通過提標改造和擴建,某汙水處理廠的處理能力從2.5×10~4m~3/d提高至5.0×10~4m~3/d,齣水水質由一級B標準提高至一級A標準.通過將常規A~2/O工藝改造為倒置A~2/O工藝、優化工藝運行、跼部改造和增加深度處理設施等措施,對BOD_5、SS、NH_3-N和TP的去除率分彆達到95.0%、96.2%、82.1%和90.4%,齣水水質達到一級A標準.詳細介紹瞭提標改造內容及採取的措施,可為類似工程的設計提供參攷.

After upgrading reconstruction and extension construction, the treatment capacity of a wastewater treatment plant was increased from 2.5×10~4 m~3/d to 5.0×10~4 m~3/d, and the effluent quality was improved from the first class B criteria to the first class A criteria. After the proposed measures, such as reconstructing the traditional A~2/O process into reversed A~2/O process, optimizing the process opera-tion condition, partial retrofitting and adding advanced wastewater treatment facilities were taken, the re-moval rates of BOD_5, SS, NH_3- N and TP were 95.0%, 96.2%, 82.1% and 90.4% respectively, and the up-to-standard discharge of the effluent was achieved. The content and measures applied during the upgrading reconstruction and extension construction are introduced, providing reference for other simi-lar projects.
