白腐真菌煤渣生物膜反应器对染料废水的脱色试验研究

Tests for Decolorization of Wastewater from Dyestuff Production by Bio_Membrane Reactor Using Coal Cinder as White Rot Fungal Biofilm Supporter

白腐真菌煤渣生物膜反应器处理模拟活性艳红染料废水 ,菌种A、B(担子菌纲)和C(云芝)最高脱色率分别达到84%、80%和95%。试验表明 ,共培养液类型对染料的脱色效果有明显影响 ,菌种C受共培养液的影响最为显著。白腐真菌煤渣生物膜反应器对实际的偶氮染料废水的脱色作用主要在初始阶段完成 ,而到72h后COD得以有效去除。当该废水的初始CODcr为6000mg/L时 ,经144h后 ,CODcr的去除率达98%。

In the treatment of simulated Reactive Brilliant Red dyestuff by bio_membrane reactor using coal cinder as white rot fungal biofilm supporter,the maximum decolorization rates with fungiA,B(Basidiomycetes)and C were 84%,80% and 95% respectively.The test showed that the types of coinoculum had obvious effects on dyestuff decolorization results.Fungus C was most significantly affected by coinoculum.The decolorization of the actual wastewater from azo dyestuffs production by the bio_membrane reactor using coal cinder as white rot fungal biofilm supporter was mainly completed in the initial stage,while COD was effectively removed in 72 hours. When the initial CODcr in the said wastewater was 6 000mg/L,the removal rate of CODcr reached 98% in 144 hours.
