摘　　要：本文在分析污泥膨胀的发生机理的前提下,阐述引起污泥膨胀的主要原因:污泥负荷、溶解氧、pH值、温度等;并提出控制污泥膨胀的一些措施:调节反应池中的溶解氧及pH值,投加营养盐合理调配营养比等。On the basis of analysis of the mechanism of sludge bulking,the main reason caused it was discussed,such as sludge loading,dissolved oxygen,pH value,temperature,etc.And some measures to control sludge bulking were also proposed e.g.to adjust the dissolving oxygen and pH value in reactors and to add some nutrition to set a reasonable nutrition rate.
