Abstract:
Taking the actual domestic sewage from the living area of the teaching staff as the substrate, the strengthening effect of adding diatomite and powdered activated carbon on aerobic granulation of activated sludge was investigated. The results showed that adding diatomite and powdered activated carbon could effectively shorten the formation time of aerobic granular sludge; the appearance and internal bacterial species of granular sludge formed by adding diatomite and powdered activated carbon were significantly different, adding micro powder would reduce the diversity of microbial population in aerobic granular sludge, and powdered activated carbon was more suitable for microbial attachment growth than diatomite; the sewage treatment efficiencies without adding micro powder and adding diatomite were poor; the reactor adding powdered activated carbon quickly formed aerobic granular sludge while retaining more biomass, the removal rates of COD and NH+4-N were 85.3% and 87.2%, respectively. Adding powdered activated carbon is an effective strategy to promote aerobic granulation of activated sludge in treatment of low concentration actual sewage.
