摘要：The paper used integrated Anammox -SAnMBR ( submerged anaerobic MBR ) reactor to cul-ture anammox bacteria .At the same time the MBR fouling was effectively alleviated through cyclic aera-tion using nitrogen generated from the oxidation of anommox bacteria .The reactor has been successfully operated for 69 days through choosing anammox floc sludge .Through experiments , the nitrogen load of the reactor is up to 1.8 kg /m3 · d and the nitrogen removal rate is up to 83%.The aeration has no sig-nificant effect on bacterial activity and particle size of anammox .Moreover , the system of recycle gas sparging was used to wash membrane surface .Compared to the condition without , the aeration is 0 .2 m3/h, the use cycle of membrane last from 4 days to 28 days.used.The paper used Lawrence -McCarty model to study the kinetic characteristics of Anammox bacteria .The real yield coefficient ( YT ) of Anam-mox sludge is 0.17 mg/mg NO2--N and the decay coefficient ( Kd ) is 0.01 d-1 .The increase rate of anammox is improved .The culture of anammox in membrane bioreactor has better advantage than other reactors.
