高效优势降解菌处理樟脑废水

针对樟脑废水,从活性污泥中筛选出降解樟脑废水的高效优势菌,通过分离纯化,优选出3株适应能力强、生长旺盛的菌株,分别为ZH-1、ZH-2、TZH-2。经初步鉴定分别为动胶菌属、假单胞菌属、短杆菌属。试验测定了樟脑混合菌最佳生长条件的优化组合为:葡萄糖质量浓度20 g.L-1,温度30℃,pH值为7,转速为125 r.m in-1,培养时间55 h。并测定了单株菌和混合菌对樟脑废水的降解效果,结果表明混合菌的降解效果最为明显,降解率为75.23%。

Study on Treatment of Camphor-containing Organic Wastewater by High- effective Microorganisms

In order to biodegrade camphor-containing organic wastewater,the strains of microorganism with highly-effective degrading capability were isolated from the activated sludge.And they were identified as Zoogloea sp.,Pseudomonas sp.,Brevibacterium sp.The growing curve and the best growing condition of the mixed highly-effective degrading bacteria were then measured,and the best training time and condition for growing such mixed highly-effective degrading bacteria were then determined.The degradation result of using the mixed highly-effective degrading microorganism verses the individual ones is compared in the lab,giving rise of the conclusion that the mixed highly-effective degrading microorganism was more efficient to degrade the above type of wastewater,with a degradation rate of 75.23%.
