%X By using a lab-scale aerated upflow sludge bed reactor,the inoculated anaerobic granule was cultivated to aerobic nitrification granule,and then converted to short-cut nitrification granule with the short-cut nitrification efficiencies above 90%.Appling real-time quantity PCR,and florescent in situ hybridization techniques,the ecological community structure of nitrification bacteria in aerobic granules were studied.The results show that there existed a layered structure in the aerobic granule,the ammonia oxidizing bacteria(AOB) was mainly located in the surface area of the granule,and the nitrite oxidizing bacteria(NOB) was mainly located in the inner area of the granule,was just adjacent to the AOB.There was no active bacteria in the inner core area.The amount of AOB in the granules increased,as the ammonia loading rate of the reactor was increased gradually.The percentage of AOB in the total amount of Eubacteria in the granule was 0.45%,5.20%,15.37%,48.55% respectively,as the ammonia loading rate of the reactor were 0,0.4,1.0 and 2.2 kg/(m3·d) respectively,and the nitrosofication efficiency were 0%,35%,50%,99% relatively.
