重庆某医院污水处理站设计规模为120m3/d,采用水解酸化—射流曝气工艺进行处理,在进水BOD5为67.0mg/L、CODcr为152.9mg/L、SS为221.5mg/L、NH3-N为21.7mg/L的条件下,处理后出水BOD5<20mg/L、CODcr<100mg/L、SS<70mg/L、NH3-N<15mg/L,达到《污水综合排放标准》(GB8978-1996)一级标准。

The wastewater treatment plant with design capacity of 300 cubic meters per day was constructed to treat the hospital wastewater by hydrolytic acidification and jet aeration process for some hospital in Chongqing City. When the inflow wastewater concentration is 67.0 mg/L, 152.9 mg/L, 221.5 mg/L and 21.7 mg/L for BOD_5, COD_(cr), SS and NH_3-N respectively, the obtained effluent will be good enough to meet the requirement of Class I in the integrated wastewater discharge standard GB8978-1996.
