nitrification-anaerobic
1.OLAND process is the novel biological denitri fi cation process developed based on the nitrous nitrification-anaerobic ammonia ox idation technology.
2.This paper studied nitrification and denitrification of mature aerobic granular which cultivated from activated sludge and anaerobic granular sludge.
3.The number of mold, bacteria, culturable microorganisms, aerobic nitrogen-fixing bacteria, anaerobic nitrogen-fixing bacteria, aerobic cellulose decomposition microbes, anaerobic cellulose decomposition microbes were the most in 16-year-old organic tea garden, and the biomass carbon and nitrification of edaphon were also the strongest.
4.The anaerobic treatment in A2/O technological process provided readable biodegradable organic carbon source for the follow-up denitrification through hydrolysis acidification action of the refractory organics and eliminated the nitrite accumulation and its inhibition on nitrification process.
5.ammonium is oxidized to dinireogen gas by particular microorganisms with nitrite as the electron acceptor under the anaerobic condition to realize the denitrification. SHARON (Single reactor High activity Ammonia Removal Over Nitrite)and OLAND(Oxygen Limited Autotrophic Nitrification Denitrification) are the most famous processes of nitration, which usually use CSTR (Continuously Stirred Tank Reactor)and MBR (Membrane BioReactor) as reactor respectively.
