Abstract

An activated sludge biomass was developed with microbial populations capable of oxidizing a broad range of organic contaminants in industrial landfill leachate. A mixed microbial population, acclimated to leachate, can degrade about 80% of the organic carbon. The carbon balance clearly indicates biological oxidation of organics. Dissolved organic carbon removal by stripping, evaporation, or sorption were not significant. The acclimated population used organic carbon and other nutrients solely from leachate and sludge yield was low. Highly concentrated hazardous wastewater (up to 10 000 mg/L organic carbon) was biostabilized rapidly. The process has significant potential for residual waste liquor renovation and disposal.
