摘要
构建白腐真菌膜生物反应器降解复配染料废水,研究营养源调控对反应器降解过程的影响。利用通过野外采集及紫外诱变得到的十五种白腐真菌,通过染料生产废水的摇瓶脱色实验,筛选出脱色能力最强的12#诱1菌种(出水色度由初始时的4000倍变为处理72h之后的15倍)作为后续实验的研究菌种。在白腐真菌膜生物反应器营养源调控研究中,得到如下结论:将碳源浓度从30g/L降低到10g/L、氮源浓度从560mgN/L(20mmol/L尿素)降低到56mgN/L(2mmol/L尿素)后,同样获得了良好的复配染料脱色效果。
A white rot fungi bioreactor was built to degrade dyeing wastewater. The effect of nutrient control on the degradation process of the bioreactor was studied. Through the test of swinging bottle, 12#U1 fungi spawn with the strongest decoloring ability was sired out of 15 optional spawns. A conclusion was drawn from the research on the nutrient control of white rot fungi bioreactor that, alter carbon source concentration lowered to 10g/L from 30g/L and nitrogen source concentration lowered to 56mg N/L （2mmol/L urea）from 560mg N/L, better decoloring effect on dyeing wastewater could be obtained similarly.
