Research of active sludge granulation at influence of stress agents in take-off and fill-up process of aerobic biological cleaning

The processes leading to formation and maintenance the stability of aerobic active sludge granules, grown up on a modeling household drain in take-off and fill-up mode were investigated, the contribution of influence of adverse factors of an environment in options of conducting processes at starvation and introduction of a stressor (H 2O 2) on formation and stability of granules community is estimated. Effectively working granules of aerobic active sludge, with high cleaning ability and stability of granules community to adverse factors are received.
