| Abstract: | Combined contact oxidation and step-feed A/O process were used to treat caffeine production wastewater.The pilot-plant results showed good effects on caffeine production wastewater treatment.Effluent with residual contents of below 300 mg/L (removal rate above 85％),30 mg/L (removal rate above 90％) for COD and NH~-N respectively were obtained.The process had strong resistance to the load capacity of inflow,and could treat the high salinity and high organic nitrogen wastewater with good economic benefits. |
