A PROCESS FOR THE TREATMENT OF DISTILLERY WASTEWATER USING AEROBIC SEQUENCING BATCH REACTOR

摘要

The present invention relates to the treatment of anaerobically digested distillery spent wash using a sequencing batch reactor by using a novel bacterial consortium. Anaerobically digested distillery wastewater combined with domestic wastewater at a ratio of 1:4 v/v and used as an influent for the laboratory scale SBR. A significant amount of COD and BOD reduction was observed with 70% and 96% respectively with 1 day HRT. SBR with a novel and synthetic fluidized biofilm support results in COD and BOD reduction of 77% and 98% respectively. SBR treated effluent when subjected to ozonation results in 90% colour removal. The above process provides for zero discharge of effluent and the treated effluent can be reused for non- process activities in distillery.
