生物水解（酸化）法处理高浓度洁霉素废水的降解机理研究

Study on the degradation mechanism of biological hydrolysis (acidification) in treating high concentration lincomycin wastewater

在应用生物水解（酸化）法处理高浓度洁霉素生产废水中试试验中，着重研究水解（酸化）反应中起主要作用的微生物菌群及其降解效率。同时采用ＧＰＣ（凝胶渗透色谱）、ＧＣ／ＭＳ（色谱一质谱）等分析手段对水解（酸化）反应过程中有机物形态变化进行研究。结果表明，在水解（酸化）反应中起主要作用的有埃希氏菌属、发酵单胞菌属、气单胞菌属、变形杆菌属、柠檬酸杆菌属等。同时，水解（酸化）反应具有将洁霉素废水中的大分子有机物降解为小分子有机物的作用，可提高废水的可生化性。

Biological hydrolysis(acidification) was investigated for the treatment of high concentration lincomycin wastewater.In a pilot experiment,the main microbes of hydrolysis(acidification) and their degradable efficiency was also studied.The difference of organic form in hydrolysis(acidification) was analysed with GPC (Gel Permeation Chromatography)and GC/MS(Gas Chromatography/Mass Spectrometer).Results showed that main microbes are Escherichia,Zymomonas,Proteus,Aerornonas and Citrobacter,and the large molecular organism can be degraded into little molecules,so as to improve the biodegradability of the wastewater.
