Abstract: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.
