- 摘要:
- 以教工生活區(qū)實(shí)際生活污水為底物，考察了分別投加硅藻土和粉末活性炭對(duì)活性污泥好氧顆�；膹�(qiáng)化作用。結(jié)果表明：硅藻土和粉末活性炭均能有效縮短好氧顆粒污泥形成時(shí)間；投加硅藻土、粉末活性炭形成的顆粒污泥外觀及內(nèi)部細(xì)菌種類存在明顯差別，投加微粉會(huì)降低好氧顆粒污泥中微生物種群的多樣性，相對(duì)于硅藻土粉末活性炭更適于微生物附著生長(zhǎng)；未投加微粉和投加硅藻土的反應(yīng)器處理污水的效果較差；投加粉末活性炭的反應(yīng)器在快速形成好氧顆粒污泥的同時(shí)還能保留更多生物量，對(duì)COD、NH+4-N的去除率分別為85.3%和87.2%。當(dāng)處理低濃度生活污水時(shí)，投加粉末活性炭是促進(jìn)活性污泥好氧顆粒化的有效策略。
- 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.
