摘要
研究用海藻酸钙包埋固定降解菌种(Alcaligenessp.),用于降解腈纶废水中的2,6-二叔丁基酚。与菌悬液相比菌种固定化包埋后,降解底物2,6-DTBP的能力大大提高。并且在活性污泥处理系统中加入固定化的包埋颗粒,其对底物的生物降解率可从35%提高到60%。扫描电镜观察到菌种在海藻酸钙包埋载体中能良好地生长。
The biodegradation of 2,6-di-tert-butylphenol(2,6-DTBP) in wastewater by immobilized microorganism(Alcaligenes sp.)is studied.The biodegradation capacity of 2,6-DTBP by immobilized microorganism is improved compared with free microorganism.When the immobilized gel is added to the activated sludge system,the biodegradation rate is increased from 35% to 60%.SEM images demonstrated the microorganism immobilized in calcium alginate gel can grow well.
