摘　　要：采用白腐菌对造纸废水处理系统的二沉池出水进行深度处理，研究了处理条件（时间、初始pH值、外加碳源、外加氮源）对处理效果的影响。实验结果表明：处理时间7天时，处理效果最好，脱色效果明显，CODcr和色度去除率分别为37．2％和65．8％；菌株初始最佳pH范围为4．5-5．0；外加碳源条件下对废水进行处理效果更好。相反，添加氮源会降低废水的处理效果。White rot fungus was used to treat effluent from secondary sedimentation tank in papermaldng wastewater treatment system.The influence of on processing conditions （such as processing time, initial pH, external carbon addition and nitrogen addition） were studied. The results showed that when the processing time is 7 days, the treatment effect is best, but decoloration effect is more obvious, the removal rate of CODer and decoloration are 37.2% and 65.8%. The optimal range of the initial pH value is 4.5-5.0. The treatment effect is better in conditions of adding carbon source, but adding nitrogen source can reduce the treatment effect.
