摘要

利用固定化C .versicolor菌丝球对 4种染料和印染废水的脱色进行了研究 .在三角瓶中采用重复分批加料方式对酸性橙溶液脱色至少可以进行 10批

每批在 2 4h内完成 97%以上的脱色效果 .菌丝球对其他 3种染料也有较好的脱色效果 .在脱色过程中添加碳源是必要的 .此外

还利用自制的气升式反应器对酸性橙和印染废水的连续降解进行了研究 .当稀释率为 0 .0 0 5 6h-1、通风量为 1.1L·min-1时

酸性橙溶液的脱色率可达 97%;当稀释率为 0 .0 14h-1、通风量为 1.4L·min-1时

印染废水的脱色率为 93.5 %

连续操作 5d后

菌丝球的脱色能力没有下降 .

Abstract

In this work

immobilized mycelial pellets were applied to decolorize several dyestuffs.Good results were obtained indicating the high decolorization ability of the pellets.The same pellets could be repeatedly used to treat Acid Orange 7 for at least 10 times and every time over 97% color removal was obtained within 24h.Good decolorization effect was also observed with 3 other dyestuffs.The presence of a co-substrate glucose was necessary for decolorization by mycelium pellets.In the continuous reactor

both Acid Orange solution and non-sterile dying waste water were treated by immobilized mycelial pellets. With dilution rate 0.0056h -1

aeration rate 1.1L·min -1

color removal rate of Acid Orange is 97%.With dilution rate 0.014h -1

aeration rate 1.4L·min -1

93.5% color reduction of dying waste water was obtained.No loss in decolorization ability of the mycelium was noted when the reactor was operated continuously for more than 5d.
