Abstract The treatment of wastewater containing medical octanol was studied by adopting a combining
process consisting of air-catalytic oxidation and chlorine dioxide as an auxiliary oxidant. After the treatment, the
organic matter in wastewater was not only effectively removed, but the effluent could be reused. The content of
dichromate COD in the treated wastewater could meet the requirement of the Chinese wastewater discharge
standard (not greater than 150 mg/L).
Key words: Wastewater containing octanol Catalytic oxidation Chlorine dioxide auxiliary oxidant
