PG  - 2710-5
AB  - The physical properties and microbiological characteristics of aerobic short-cut 
      granular sludge, which was cultivated in a lab-scale aerated upflow sludge bed 
      (AUSB) reactor, were investigated. When the short-cut nitrification process was 
      performed stably, the ratios of VSS/ SS of short-cut granules were kept at about 
      80%, the amount of granules with diameter larger than 1.0 mm was about 70% of the 
      total, and the wet density of granules with diameter larger than 0.8mm was about 
      1022 kg/m3. The fluorescence in situ hybridization (FISH) results indicated the 
      ammonia oxidation bacteria (AOB) were mainly located in the surface layer of the 
      granules, and the nitrite oxidation bacteria (NOB) were in the inner layer. The 
      results of most probable number (MPN) showed that, as the short-cut process was 
      operated stably, the amount of AOB was much more than that of NOB, and sometimes 
      the AOB amount was even 10 thousands times more than that of NOB. All these 
      results indicated that, using the seed granules or their debris as the support 
      media, AOB and NOB were attached and grown on the surface of the media, and 
      finally the aerobic short-cut nitrification granules were formed.
