抄録

A solution of molasses wastewater, pre-treated by activated sludge, was ozonated and then completely decolorized by ozone. Total organic carbon (TOC) could be reduced only to about 50% during a period of 60 minutes ozonation. The ozonated solution, after being mixed with activated sludge culture, was incubated for 10 days at 25°C, and biodegradability was then assessed by dissolved organic carbon (DOC) reduction. DOC of the non-ozonated solution could hardly be reduced even after 10 days incubation, indicating biodegradability. It only be slight. For the ozonated solution of pre-treated molasses wastewater, DOC removal more than 70% was achieved and DOC in the solution was less than 10mg·l^-1. Ozonation thus greatly improves the biodegradability of refractory organic compounds. A solution of molasses wastewater was ozonated directly. Ozone decolorized about 90% of the molasses wastewater but TOC was reduced to only about 8%. Biodegradability of ozonated molasses wastewater was improved much more than that non-ozonated.
