曝气生物流化床反应器处理动车集便器污水脱氮及微生物研究OA北大核心
Denitrification and Simultaneous Nitrification Microbial for Treatment of Enclosed Passenger Train Toilet Fecal Wastewater by Aerobic Biological Fluidized Bed Reactor
应用好氧曝气生物流化床反应器处理动车集便器粪便污水，研究反应器同步硝化反硝化脱氮效果；考察不同影响因素条件下反应器脱氮效果。结果表明：反应器能够较好地同时实现硝化和反硝化两个过程；DO为2.5 mg/L时，同步硝化反硝化脱氮效果最佳；最佳pH值范围为7.0~8.0；反应器在C/N比为1.6时脱氮效果较好；温度在18~25℃变化，对反应器脱氮效能影响不明显；微生物DNA纯度高，氨氧化细菌的生物多样性高。
The enclosed passenger train toilet fecal wastewater is treated with the aerobic biological fluidized bed reactor. The efficiencies of simultaneous nitrification and denitrification in reaction are studied and the effects of denitrification with reactor are assessed under different conditions. The results show that the reactor can well fulfill nitrification and denitrification processes simultaneously with the best denitrification performance at DO of …查看全部>>
