摘　　要：利用发光细菌法测试了蔗渣浆CEH漂白废水的毒性,对比了在有残氯和无残氯两种情况下,漂白废水毒性的变化。结果发现,废水中残氯含量越高,废水毒性的增率越大,残氯对测试生物毒性有重要影响,在研究纸浆漂白废水中主要有机物的毒性时要注意消除废水中的残氯。A photobacteria method was used to test the toxicity of the CEH bleaching effluent of bagasse kraft pulp, the toxicities of the effluents with residual chlorine and without residual chlorine were compared. It was found that the residual chlorine had important effect on the toxicity testing; the higher residual chlorine caused higher toxicity of the effluent. Therefore, the residual chlorine should be removed in the study of organic material toxicity of bleaching effluent.
