摘要
气相色谱─质谱分析检测表明：苇浆ＣＥＨ漂白的氯化段和碱处理段废液中均含有氯代酚和氯代愈创木酚，氯化段废液中的氯代酚相对含量高于氯代愈创木酚，碱处理段废液中两类氯代酚类化合物的相对含量接近。次氯酸盐漂白段废液中的氯代酚类化合物含量极少。经过载体吸附法固定的白腐菌处理之后，苇浆ＣＥＨ漂白混合废液中的氯代酚类化合物含量大为降低。
GC-MS observation revealed that chlorophenol and chloroguaiacol existed in discharged effluents from the first two-stages of a CEH bleaching of reed pulp. No chlorinated phenolic compounds was found in the hypochlorite effluents.The bleaching effluents were treated with immobilized white-rot fungi P.chrysosporium, It was found that most of the chlorinated phenolic compounds were no more existed.
