白腐真菌生物法处理染料亚甲基蓝的研究

Decolorization of the dye wastewater by White-rot fungi in liquid culture

实验采用白腐菌降解染料亚甲基蓝,研究了在不同振荡条件下,不同浓度的亚甲基蓝、染料废水的不同培养时间、不同转速、碳源的不同浓度等条件对染料亚甲基蓝的脱色效果的影响。实验结果表明,白腐菌在无氮条件下,染料亚甲基蓝浓度为4mg/L,振荡速度为120rpm,碳源浓度为2.0%时,其降解能力达到最大,脱色率为78.5%。

Experiment using white-rot fungi degrade the dye of methylene blue, studied in different oscillation condition such as different concentrations of methylene blue, different training time of dye wastewater, the different speed, different concentrations of carbon source, which is influence the methylene blue's decoloring effect. Experimental results show that the white-rot fungus under the conditions of without nitrogen, the concentration of methylene blue dye is 4mg/L, oscillation speed for 120rpm, carbon source for 2.0%, it’s degradation ability achieve maximum, the decolored rate is 78.5%.
