Abstract

Biological treatment of wastewaters discharged by wood manufacturing industry is a problem due to the high toxicity and recalcitrant due tannin, lignin and chlorophenol compounds. In the present work the continuous biodegradability of the pulp and paper effluent by two type of reactor Anaerobic Filter (FA) and Upflow Anaerobic Sludge Blanket (UASB). These recalcitrant compounds removal and color are determined. Results show a removal efficiency of BOD5 above 90% after 40 days of operations. However only a partially biodegradation (10-30%) of tannin and lignin and no color reduction was observed.
