关于氧化沟均衡设计方法的探讨

Probing into the Balanced Design Method of Oxidization Ditch

在确定氧化沟曝气设备的过程中， 需要同时满足生物反应动力学和水动力学两方面的要求， 即既要满足微生物需氧量的要求， 又要满足氧化沟混合液设计流速的要求。本文通过分析氧化沟中的水流阻力及曝气设备对混合液的推动和提升作用，拟出曝气设备的性能参数和氧化沟几何条件与混合液平均流速的关系， 提出了氧化沟的均衡设计及确定氧化沟几何尺寸的设计方法。

In the process of determining aeration equipment, the balance between the rate of oxygen supply and the design flow velocity are required simultaneously. This paper is intended to provide a systematic design method for a balanced oxidization ditch that involves process kinetics, hydraulics and disc aerator functioning. The geometry of an oxidization ditch is also defined.
