摘　　要：好氧颗粒污泥难以快速、稳定形成是限制其大规模工程化应用的重要原因,鉴于此,以大学校园生活区污水为底物,利用序批式反应器(SBR)研究了投加铁碳微电解填料对好氧污泥颗粒化的强化作用。结果表明,铁碳微电解填料能提高活性污泥的沉降性、有效缩短好氧颗粒污泥的形成时间,同时铁碳原电池反应生成的惰性碳粒晶核有助于更多世代时间较长的微生物(硝化菌)附着生长。投加铁碳微电解填料是实现铁碳微粉缓释、强化好氧污泥颗粒化的有效策略。The rapid and stable formation of aerobic granular sludge is a challenge that restricts its large-scale engineering application.Therefore,Fe/C micro-electrolysis filler was added into a sequencing batch reactor(SBR)to enhance aerobic sludge granulation for the treatment of domestic sewage from a campus living area.The Fe/C micro-electrolysis filler improved the settling velocity of the activated sludge and effectively shortened the formation time of aerobic granular sludge.In addition,the inert carbon nuclei generated by iron carbon galvanic cell reaction was conducive to the attached growth of more microbes with longer generations(such as nitrifying bacteria).Adding Fe/C micro-electrolysis filler is an effective strategy to realize slow release of Fe/C micro-powder and accelerate aerobic granulation.
