通过驯化富集培养,从处理苯胺废水的反应器中分离出3株苯降解菌BA1、BA2、BA3,研究了投加单个及复合菌种对苯胺废水生物处理的增强作用。结果表明,投加Fe3+和复合菌种均能促进难降解有机物的降解,提高苯胺废水COD去除率,当3者协同作用时,效果最好,并确定了最佳菌种组合。 By acclimation and enrichment culture, three strains of benzene-degrading bacteria, BA1, BA2 and BA3, were isolated from the reactor for treating aniline wastewater. The enhancing effects of single and multiple strains on the biological treatment of aniline wastewater were studied. The results showed that adding Fe3 + and composite strains could promote the degradation of refractory organic matter and improve the COD removal rate of aniline wastewater. When the three were synergistic, the effect was the best, and the best combination of bacteria was determined.
