A MULTI-ZONE ATTACHED GROWTH BATCH BIO-REACTOR METHOD OF BIOLOGICAL TREATMENT OF DOMESTIC WASTEWATER

摘要

The present invention describes a multi-zone attached growth batch bio-reactor & method thereof for biological treatment of domestic wastewater consists of a single processing tank, wherein the single processing tank comprising: a facultative anoxic zone (A), a bio-carrier zone (B) for growth of bio-mass in communication with anoxic zone; a aeration zone (C) in communication with bio-carrier zone (B); an inlet for introducing waste water to be treated in the facultative anoxic zone (A); wherein the said anoxic zone (A) is disposed adjacent to the said bio-carrier zone (B) and the said aeration zone (C) is disposed above the bio-carrier zone and each zone is interlinked with a passage for transfer of waste water treatment.
