UBF实现同步反硝化产甲烷的启动与运行特征
Start-up and operation characteristics of UBF reactor for simultaneous denitrification and methanogen-esis
摘要
Abstract
[Objective]In this paper ,it was the research purpose that seeking the rapid startmethod of simultaneous deni-trification and methanogenesis (SDM ) process and observing stable operation characteristics of SDM after start-up . [Methods]The up-flow anaerobic sludge bed-filter (UBF) was used for treating landfill leachate with high C/N ,and the associated way of aerobic precoating-anaerobic acclimation was selected to implement start process ,which achieved SDM function in the UBF reactor finally .[Results]The whole start-up process lasted for 42 d ,the sludge concentration was about 9.5 g·L -1 in the sludge bed ,and the amount of biofilm was 5.2 g·g -1 filler in packed bed;Under high C/N the treatment effect of UBF reactor was very stable ,and total removal rates of CODCr ,NO3 --N ,NH4 +-N and TN were 88.83% ,99.95% ,70.97% and 82.80% respectively and substrate degrading efficiencies were higher;The daily production of biogas was about 7.2~8.9 L and the composition of biogas was stable ,and average content ratios of CH4 、CO2 、H2 and nitrogen gas were 54.41% ,44.09% ,0.58% and 0.92% respectively .[Conclusion]Therefore ,for the UBF reactor ,the associated way of aerobic precoating-sludge anaerobic acclimation could be used for the fast a-chievement of SDM function ,and the stable and good operation effect was acquired .关键词
