摘　　要：利用从腈纶废水处理厂中分离出来的一株2,6二叔丁基酚高效降解菌F34菌株,进行生物强化处理技术研究。通过对照环境中的2,6二叔丁基酚降解效果的比较分析,发现包埋后的F34菌株降解底物的能力相比游离的略有提高;F34菌株在活性污泥存在时受到其抑制作用,通过包埋,菌株所受的抑制作用减弱;在含活性污泥的B.H.和实际废水的环境中,投加F34菌株包埋颗粒显著改善了原系统对底物的处理能力,其对底物的去除率分别提高了164%和71.4%。A study on bioaugmentation treatment for 2,6-Di-tert-butylphenol(2,6-DTBP)was undertaken in analog environment by using a high effective degrading bacterium strain F-3-4 for 2,6-DTBP, which was screamed out from acrylic fiber wastewater treatment plant.Through the comparisons and analysis on the degradation efficiency of 2,6-DTBP in different environments, it was found that though the strain can be inhibited when coexist of activated sludge, the inhibition would be weakened if it was immobilized with calcium alginate.The removal capability of the activated sludge system in B.H.basic medium bioaugmented with immobilized strain F-3-4 was enhanced by 164%,so did that in acrylic fiber wastewater by 71.4%.
