摘要:
以教工生活区实际生活污水为底物，考察了分别投加硅藻土和粉末活性炭对活性污泥好氧颗粒化的强化作用。结果表明：硅藻土和粉末活性炭均能有效缩短好氧颗粒污泥形成时间；投加硅藻土、粉末活性炭形成的颗粒污泥外观及内部细菌种类存在明显差别，投加微粉会降低好氧颗粒污泥中微生物种群的多样性，相对于硅藻土粉末活性炭更适于微生物附着生长；未投加微粉和投加硅藻土的反应器处理污水的效果较差；投加粉末活性炭的反应器在快速形成好氧颗粒污泥的同时还能保留更多生物量，对COD、NH+4-N的去除率分别为85.3%和87.2%。当处理低浓度生活污水时，投加粉末活性炭是促进活性污泥好氧颗粒化的有效策略。
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.
