摘要
好氧颗粒污泥是一种污水处理新方法,具有沉降速度快和耐毒性等优点。但是,好氧颗粒污泥存在培养周期长、成熟颗粒易解体等问题,导致好氧颗粒污泥工业化推广难以实施。本文重点阐述沉降速度、盛宴期/饥饿期条件、水力剪切力、有机负荷率、底物组成对好氧颗粒污泥培养的影响以及好氧颗粒污泥在处理废水中的应用。
Aerobic granular sludge is a new wastewater treatment method,which has the advantages of fast sedimenta⁃tion rate and toxicity resistance.However,the aerobic granular sludge has some problems such as long incubation pe⁃riod and easy disintegration of mature particles,which makes it difficult to implement the industrialization promotion of aerobic granular sludge.In this paper,the effects of sedimentation rate,feast/starvation stage conditions,hydraulic shear force,organic loading rate and substrate composition on the cultivation of aerobic granular sludge and the appli⁃cation of aerobic granular sludge in wastewater treatment are described.
