摘要：

Three distinct pulp mill bleachery effluents, derived from a chlorine-alkali-hypochlorite (CEH), an alkali-oxygen-peroxide (EOP), and a hypochlorite-chlorine dioxide-alkali-hypochlorite (HDEH) bleaching stage were treated with the white-rot fungi Phanerochaete chrysosporium and Trametes versicolor. Color units as well as absorbance in the UV (280 nm) of the CEH and HDEH effluents were diminished significantly by both fungi, whereas the EOP effluent lignins appeared recalcitrant. Toxicity was found to be highest in the chlorine-free EOP effluent. T. versicolor diminished the toxicity of both the CEH and the EOP effluent by about 35%, but caused no detoxification of the HDEH effluent.
