Dynamic simulated experiment in treatment of special organic wastewater by A/O process.

The best process of treating wastewater was defined by flocculation. toxic and biochemical experiment. The concentration of wastewater and stay time affecting the removal efficiency of COD were studied. Experiment results showed; treating organic wastewater by flocculation was not very effective and organic wastewater inhibited biochemical treatment, when the influent COD was 3000mg/g and flow was 1L/h, after being treated by A/O/O the effluent COD can be reduced to less then 150mg/L with the total removal efficiency more then 95% to meet the wastewater discharge standard.
