摘要
石家庄市桥西污水处理厂一期升级改造工程规模为16×104m^3/d。设计将原普通曝气工艺改造为分段进水多级AO工艺,改造后的出水水质由原二级标准提高为一级A标准。投产运行后,出水水质基本达到设计标准。对改造工艺设计进行了详细阐述,可供类似工程参考。
The design capacity of first-phase upgrading and retrofit project of Shijiazhuang Qiaoxi WWTP was 16 × 10^4 m^3/d. The original ordinary aeration process was transformed into the step-feed multistage A/O process, and the effluent quality was improved from the second level criteria to the first level A criteria. The effluent quality could reach the design standard after putting into operation. The design of the retrofit process was elaborated for reference to similar projects.
