Abstract The removal of 4,6-dinitro-o-cresol (DNOC) was investigated using an anaerobic recycle fluidized bed reactor as a pretreatment stage followed by an activated sludge reactor. The DNOC was completely converted during the anaerobic pretreatment stage for influent DNOC concentrations as high as 600 mg/1. While complete conversion of DNOC occurred during the anaerobic pretreatment stage, there was only 25% COD removal. The subsequent aerobic activated sludge stage reduced the anaerobic stage effluent COD by 80%, resulting in about 85% overall removal. Batch tests established a range of DNOC loading rates for the anaerobic fluidized bed. The batch tests also indicated that DNOC did not degrade in the absence of a readily biodegradable co-substrate, and could not be used as a single carbon source by the anaerobic bacteria. This investigation used sucrose as the co-substrate. Anaerobic DNOC biodegradation was found to be a function of sucrose concentration. Previous investigation of aerobic treatment of DNOC using conventional activated sludge process showed that DNOC removal is less than 25% and the concentration of DNOC that is tolerated by activated sludge microorganisms is only about 50-60 mg/1. The present investigation demonstrated that anaerobic-aerobic treatment is an effective treatment process for the removal of DNOC.
