Objective To investigate the status of wastewater treatment of hospital sewage in Jinan. Methods The indices of COD, NH3,N and PO43- in sewage discharged from 16 hospitals before and after treatment and the content of residual chloride and fecal coliform counts in treated sewage were monitored in 2002 in Jinan. The monitoring results were evaluated according to the Criteria for Wastewater Discharge (GB/T8978-1996) and compared with the analytic results obtained in the year 2001. Results The COD, NH3,N and PO43- of the sewage of 16 hospitals before treatment were 253.8, 47.76 and 3.134 mg/L respectively with the over standard rate 81%, 88% and 100% respectively. The COD, NH3,N, PO43-, content of residual chloride and fecal coliform counts in treated sewage of 16 hospitals were 40.5, 6.30, 0.580, 26.7 mg/L and
