摘　　要：利用固定化驯化白腐菌能有效处理氯漂Ｅ段废水。废水色度随ｐＨ 值变化而变化， 通过紫外光谱图分析， 证实处理过程中废水中的酚类物质被除去， 且主要发生于处理过程的前期。E stage effluent of reed kraft pulp chlorine bleaching was effectively decolorized by immobilized and acclimatized white-rot fungi, 50% color unit of the effluent could be removed by Polytictus versicolor and Phlebia radiata during the incubation for 24h. It was found that color in untreated or treated effluent was different when pH of the effluent was adjusted from 4 5 to 7 6 and the differences of color unit decreased with the increase of treating duration. It was confirmed by UV spectrometry that the differences of color varied with the change of pH originated in the production of ionized phenolic groups, and phenloic substance in effluent was predominantly degraded in the initial stage of the biological treatment
