Experimental study on treatment of MBR effluent of SODO catalytic ozonation technology

摘要

This experiment used SODO ozone catalytic oxidation technology treated MBR effluent of a advanced treatment project of water treatment company in pilot scale test, which studied the effect of SODO oxidation and resolved the problem of MBR effluent drainage system can not meet the standards of "Discharge standard of pollutants for municipal wastewater treatment plant " (GB18918-2002). Operating parameters of the test device: Ozone dosage was 200mg/L·h, system contact oxidation time was 4h, the average of effluent COD_(Cr) was about 100mg/L by controlled the dosage and other parameters at the economical operating conditions.
