摘　　要：本文设计了一种适合于白腐菌ｐｈａｎｅｒｏｃｈａｅｔｅ ｃｈｒｙｓｏｓｐｏｒｉｕｍ 处理漂白废水的活性炭———化学纤维固定膜反应器，对漂白废水的脱色率达６０ ％ ～９０ ％ ，ＣＯＤｃｒ 去除率在５０ ％ 以上。本文还探讨了菌膜生长的营养条件和废水组成对处理效果的影响。最后通过用Ｈ２Ｏ２ 对废水进行的脱色处理，验证了白腐菌脱色类似于Ｈ２Ｏ２ 的作用。A bioreactor called activatied carbon_chemical cellulose immobilized fungal membrane reactor,suitable for white rot fungus phanerochaete chrysosporium to treat bleach effluent,is designed.The treatment results are influenced by the nutrient conditions of growth medium and effluent preadjustment,.Under favorable conditions,the decolorization rate is 60%-90%,CODcr removal rate is over 50%.The mechanisms of decolorizatin are verified by comparing of the decolorization result of white rot fungus with the result of chemical decolorization using.H 2O 2.
