摘要
分别对推流式曝气池的有机物降解模式和需氧模式进行了推导，并提出了同时运用这两个模式绘制需氧量曲线，将推流式曝气池设计成渐减曝气工艺的方法。
The organic degradation model and oxygen demand about the conventional plug-flow aeration tank are deduced. Themethods to draw oxygen demand curve with the models and to designing the tapered aeration process of the tank are proposed.
