Characteristics of aerobic granules grown on glucose a sequential batch shaking reactor

Abstract： Aerobic heterotrophic granular sludge was cultivated in a sequencing batch shaking reactor(SBSR) in which a synthetic wastewater containing glucose as carbon source was fed. The characteristics of the aerobic granules were investigated. Compared with the conventional activated sludge flocs, the aerobic granules exhibit excellent physical characteristics in terms of settleability, size, shape, biomass density, and physical strength.Scanning electron micrographs revealed that in mature granules little filamentous bacteria could be found, rodshaped and coccoid bacteria were the dominant microorganisms. 作 者： CAI Chun-guang    ZHU Nan-wen    LIU Jun-shen    WANG Zhen-peng    CAI Wei-min   作者单位： CAI Chun-guang,ZHU Nan-wen,WANG Zhen-peng(School of Civil and Environmental Science and Engineering, Shanghai Jiaotong University, Shanghai 200240, China)
