联邦德国几种曝气设备的性能及应用

Characteristics and Application of Some Aerators of West Germany

曝气设备的充氧性能及其数据对处理厂曝气系统的选择、设计及处理厂的费用都有很重要的意义。本文对联邦德国几种主要的曝气设备的性能及应用情况做了简要地论述。其中包括一些常规的曝气设备和一些较新的及其他一些曝气方法。给出这些设备的一些重要性能数据及曲线;也分析了这些设备应用中存在的问题。一定程度地反映了该国本领域的主要水平和状况。文后附该国清水充氧测试的基本条件和要求,以供参考。

Performance data of aeration equipment are very important to selection and layout of aeration system and to cost of wastewater treatment plant. This article is briefly concerned with the characteristics and application of some aeration units used in west Germany, which include same common aeration equipment and some modern units. The important performance data and curves of the aeration units are given. Their a few problems are also discussed. It represents typical state-of-art in the aeration area of this country. General experimental condition and procedures of this country for determination of oxygen transfer coefficient in tap water is attached to this article.
