摘要：

曝气技术与设备一直是活性污泥处理工艺中的主要组成部分,但目前使用的曝气设备存在着诸多不足之处,影响了整个处理工艺的运行.作者对悬挂链移动曝气技术与设备分三部分进行了介绍,主要阐述了针对传统曝气技术在曝气设备、运行工艺和构筑物形式等三方面进行的改造.通过对悬挂链移动曝气技术与设备的研究,为今后我国兴建污水处理厂提供了一条低投资、高效能的途径,使我国在较短时间内提高污水处理率成为可能.

Abstract:

Aeration technology and equipment are always the main part in the activated sludge treatment technology.But now there are many deficiencies in using aeration equipment,thus giving an impact on the running of treatment technology on the whole.The suspended chain moving aeration technology and equipment will be introduced in three parts;mainly about the reform of aeration equipment,running technology and structure form of the traditional aeration technology.These researches presents a way to build a sewage plant in our country with a low investment and high efficiency and makes it possible to increase sewage treatment efficiency in a short time.

Key words: suspended chain, moving aeration, fixing aeration
