Anaerobic ammonium oxidation(Anammox)is an important discovery in the field of microbiology and environmental science and is of scientific and practical valuable.It has been proved that both nitrifying and denitrifying bacteria are also of Anammox activity in addition to planctomycetes known as Anammox bacteria early.To use anaerobic granular and nitrifying sludges

as well as autotrophic and heterotrophic denitrifying sludges as insition

Anammox reactor can be successfully started up.Four phases i.e.bacterial lysis phase

lag phase

exponential growth phase and stationary phase are emerged successively during the start-up

and so the start-up process can be regulated and controlled in time.Super high efficiency of Anammox reactor at both lab-scale and full-scale has been demonstrated with average volumetric nitrogen removal rate of 50.75 kg8226;m-38226;d-1 and 9.50 kg8226;m-38226;d-1

respectively.
