| 中文摘要 |
| 对降解PVA的共生菌B1、B2在PVA降解过程中的作用及其B1+B2混合菌的PVA降解性能进行研究 .结果表明 ,B1+B2混合菌在PVA降解过程中 ,B1为B2提供生长因子 ,B2产生PVA降解酶 ,是降解者 .在摇瓶试验中 ,B1+B2混合菌在PVA浓度为 0.1、0.5、1g/L时 ,PVA降解效率均达到80%以上 .用生产废水进行试验 ,当温度为 30℃ ,处理 12h后 ,CODCr去除率达到70%左右 . |
| 英文摘要 |
| From printing and dyeing actived sludge,PVA- degrading symbiotic bacteria was isolated.The symbiotic bacteria is composed of B1 and B2.During PVA biodegradation,B1 produces a certain growth factor for B2,B2 produces PVA-degrading enzyme.The PVA-degrading characters of the symbiotic bacteria are examined.When the concentration of PVA was 0.1,0.5,1g/L respectively,more than 80% of PVA was degradated after 7days. During the treatment of the dyeing and printing wastewater, when the temperature was 30℃,the removal of CODCr was 69.75%,the proper treating time was 12h. |
