BIOLOGICAL TREATMENT OF REFRACTORY ORGANIC CHEMICALS IN INDUSTRIAL WASTEWATER

摘要

Crompton Co./Cie. in Elmira, Ontario, Canada is evaluating treatment methods of furtherrnimproving its industrial wastewater effluent quality. A pilot scale activated sludgernsystem was started to determine its effectiveness in treating the thermophilic biologicalrneffluent from the existing industrial wastewater treatment system. Preliminary resultsrndemonstrated that an additional 95% biological oxygen demand (BOD) and 65%rndissolved organic carbon (DOC) removal was achieved. In addition, significantrnbiodegradation of the refractory organic compounds was also observed.
