摘　　要：好氧颗粒污泥由于良好的沉降性,高生物量以及兼具好氧、厌氧的微环境等特点而引起关注。污水进水碳/氮(C/N)是影响好氧颗粒污泥的快速培养及性能的一个重要因素。本文探究了C/N对颗粒污泥快速培养及性能的影响。结果表明过低或过高C/N不易快速形成颗粒污泥,最佳C/N为8。当C/N由2增加至8时,SVI降低,MLSS升高,而继续增加C/N至15时,SVI升高,MLSS降低。当C/N为8时,颗粒污泥对COD、磷酸盐和总氮的去除效率分别为89%、95%和81.6%。Aerobic granular sludge is paid attention to with its good sedimentation,high biomass and both aerobic and anaerobic microenvironment.The influent carbon/nitrogen(C/N)is an important factor affecting the rapid culture and performance of aerobic granular sludge.This paper has explored the impact C/N on granular sludge rapid culture and its performance.The results show that excessive low or high C/N is not easy to quickly form granular sludge and the optimal C/N is8.When C/N increases from2to8,SVI decreases and MLSS increases,while continuing increasing C/N to15,SVI increases and MLSS decreases.When C/N is8,the removal efficiencies of granular sludge on COD,phosphate and total nitrogen are89%,95%and81.6%respectively.
