摘要：

研究了吐温、鼠李糖脂、硫酸铜和乙醇等不同添加物对白腐菌处理黑液效果的强化作用,发现鼠李糖脂能够较好地强化修复效果,当其质量浓度在50～60 mg/L时处理效果最佳。将产生鼠李糖脂的铜绿假单胞菌与白腐菌共同接种黑液后培养,可将COD降低44%。本研究为黑液的微生物处理提供了新的思路。

Abstract:

The enhancement effects of different additives,including tween,rhamnolipids,CuSO4,ethanol,etc. on the treatment of white-rot fungi treated black liquid have been studied. It is found that rhamnolipids can enhance reme-diation effect better. When its mass concentration is in the range of 50-60 mg/L,the treatment effect is the best. Culturing after the rhamnolipid-producing Pseudomonas aeruginosa strain and white rot fungi inoculate black liquor,the COD can be reduced by 44%. This research provides a new idea for the microbial treatment of pulping black liquid.

Key words: white rot fungi(Phanerochaete chrysosporium), pulping black liquor, rhamnolipid, Pseudomonas aeru-ginosa
