| 摘 要： | 采用海藻酸钠—壳聚糖—活性炭(SA-CA-PAC)生物微胶囊包埋优势降解菌用于生物流化床处理邻二氯苯废水。比较了微囊化菌和悬浮菌对废水的降解效果,同时考察了初始浓度、接种量、pH值、温度和曝气量对降解率的影响。结果表明,微囊化菌比悬浮菌拥有更适宜的生长环境,具有更好的pH稳定性和热稳定性。微囊化菌的降解效果优于悬浮菌,处理150 mg/L的邻二氯苯废水的最佳接种量为10%,最适pH为7.5,最适温度为30℃。 |

| Abstract: | A high performance biodegradation bacteria in degrading 1,2-dichlorobenzene was encapsulated in the alginate-chitosan-powder active-carbon(SA-CA-PAC) microcapsule to deal with wasterwater in fluidized bed.Microcapsuled bacteria was compared with suspended bacteria on the removal efficiency of 1,2-dichlorobenzene and the effects of initial concentration,inoculation quantity,pH and temperature and aeration rate on degradation were studied.The results showed that microcapsuled bacteria provides a more suitable growth environment,with better pH stability and thermal stability.The removal efficiency of microcapsuled bacteria was apparently superior to that of suspended bacteria,and the optimal conditions for degrading 1,2-dichlorobenzene was inoculation quantity of 10%,pH of 7.5,temperature of 30 ℃,and aeration rate of 120 L/h. |
