Abstract

This paper describes the use of photocatalysis to degrade two bleaching effluents from P. radiata (D_oE_∞) and E. grandis (CE_op) wood processing. Organic matter oxidation was followed by general parameters (TOC, color, AOX), toxicity and biodegradability. Reactions with suspended and supported catalysts, TiO₂ and ZnO, were carried out for comparison. For both effluents, photocatalytic treatment led to an improvement in biodegradability and a reduction in acute toxicity.
