混合培养体系对实际染料废水的脱色与降解研究

[目的]研究混合培养体系对染料废水的脱色和降解务件，为印染工业废水的大规模生物处理奠定基础。[方法]利用4株丝状真菌和4株细菌组建一真菌细茵混合培养体系，考察了该混合培养体系在不同条件下对2种染料废水的脱色与降解效果。[结果]2种废水在中和预处理使pH在6．0左右后，真菌与细菌以2：1同时接种效果较好，通氧有利于脱色与降解，处理时间因水质而异。对深蓝废水12h脱色率和降解率分别达到98．36％和92．70％；对难于脱色的中红废水24h脱色率和降解率分别达到87．22％和82．98％。通过全波长扫描图谱，证明了大部分染料被降解。[结论]通过研究确定了该混合培养体系对染料废水脱色和降解的最佳条件。

Decolourization and Degradation of Dye Wastewater by Co-culture Group

[Objective] To study the decolourization and degradation conditions of dye wastewater by Co-culture group,so as to lay foundation for the large-scale biological treatment of dye industrial wastewater.[Method] A Co-culture group was set up by 4 filamentous fungus and 4 bacteria,and its decolourization and degradation effects on 2 kinds of dye wastewater were reviewed under different conditions.[Result] After the neutralization pretreatment by setting the pH value of two wastewater at around 6.0 and the simul...
