    摘要:

    通过摇瓶试验研究了缺氧条件下培养驯化污泥缺氧反硝化特性和氮杂环化合物喹啉的去除规律以及pH值、碳氮比和生物铁对喹啉去除的影响,并对喹啉生物降解产物和降解途径进行了测定与分析.结果表明:喹啉的去除主要经过吸附解吸降解三步;反应的最佳pH值范围为7~9;碳氮比对喹啉的去除影响不大;生物铁法不能提高喹啉的去除;喹啉可以单独作为碳源和氮源进行生物降解.

    Abstract:

    A study was made of the anoxic degradation and removal of nitrogenous heterocyclic compoundquinoline,denitrification of acclimated sludge as well as the effect of pH,C/N ratio,bioferric on degradation of quinoline under anoxic conditions by flaskshaking tests.The microbial degradation products were measured and the degradation pathway of quinoline in anoxic condition was analyzed.The results indicate that quinoline is removed by three steps:biosorption,desorption and biodegradation.The optimal range of pH is between 7 and 9.The C/ N ratio does not affect the reduction of quinoline obviously.Bioferric process cannot improve the degradation of quinoline,quinoline can be used as the sole carbon and nitrogen sources for biodegradation.
