Anaerobic Ammonia Oxidation Biological Nitrogen Removal in UASB Reactor at Room Temperature
摘要
Abstract
[Objective]The research aimed to study the denitrification effect of anaerobic ammonia oxidation reactor at room temperature.[Meth-od]Fed with artificial wastewater and seeded with activated sludge from an oxidation ditch at a municipal wastewater treatment plant,a 3.2 L UASB anammox reactor was to experiment the biological nitrogen removal at room temperature(22-29℃).[Result]The average removal effi-ciencies of NH4+-N and NO2--N reached 93.5%and 86.1%respectively after 75 days operation,and the ratio of removed ammonia,removed nitrite and produced nitrate was 1.00:1.30:0.31.It could realized the anaerobic ammonia oxidation biological nitrogen removal.The activity of bacteria could quickly recover at room temperature(17-25℃)only need 16 days in after the reactor shutdown for nearly 3 months,and the aver-age removal efficiencies of NH4+-N and NO2--N reached 96.6% and 90.1% respectively.[Conclusion]The anaerobic ammonia oxidation reactor can start-up at room temperature,and achieve the efficient nitrogen removal.关键词
