METHOD AND SYSTEM FOR SLUDGE OZONATION IN A WASTEWATER TREATMENT SYSTEM

摘要

Method and system (10) for treating wastewater includes treating sludge with ozone in a plug- flow type reactor (30) to cause lysis of biosolids in the sludge. The ozonated sludge may be provided to an anaerobic or anoxic section (16) of the wastewater treatment system to aid the denitrification processes occurring in the anaerobic or anoxic section (16) of the wastewater treatment system or to other sections of the wastewater treatment system such as a fermenter, an aerobic digester, or an anaerobic digester.
