• 摘要：三槽式切换氧化沟运行工况呈周期性的变化。根据理论分析,建立了各槽活性污泥进度变化及相互关系的数学模式,并进行了验证。同时就数字模式在周期程序设置及排泥方式选择时的应用做了说明。

• Abstract：Operating state of triple ditch varies periodically, Based on theoretical analysis mathe-matic models for describing variation in activated sludge concentration in each ditch and con-centration relationship between side and middle ditches were proposed and verified.The ap-plications of the models on setting up of periodic operation programmes and discharging ofsurplus activated sludge were also discussed.

• Key words：oxidation ditch  operating state  mathematic model
