摘　　要：呼和浩特市某制药公司污水处理站设计水量为900 m3/d,原出水水质无法达到《发酵类制药工业水污染物排放标准》(GB 21903—2008)要求,因此,需进行提标改造。将原先的好氧池按照1∶2∶3比例分为三段,将最后段采用MBBR工艺进行改造,同时增加回流系统,对气浮池出水增设内循环微电解/Fenton/混凝沉淀深度处理工艺。改造后,污水处理站运行效果良好,出水水质满足《发酵类制药工业水污染物排放标准》(GB 21903—2008)。The design capacity of a wastewater treatment station of a pharmaceutical company in Hohhot was 900 m^3/d. The original effluent quality could not meet the Discharge Standards of Water Pol- lutants for Pharmaceutical Industry -- Fermentation Products Category （ GB 21903 - 2008 ）. Therefore, the treatment station needed to be upgraded. The original aerobic tank was divided into three sections in 1 ： 2 ： 3 ratio, and the last section was transformed with MBBR, meanwhile, the recycle system was added, and advanced treatment process of the effluent from air flotation tank was added. After the reconstruction, the wastewater treatment station had good operation effect, and effluent quality could meet the Discharge Standards of Water Pollutants for Pharmaceutical Industry -- Fermentation Products Category （ GB 21903 - 2008 ）.
