Survey and application of flotation to water treatment

doi:10.11894/1005-829x.2004.24(7).9

Abstract

Abstract:

Dissolved air flotation(DAF), which is applied more and more to water plants, is reviewed, including its origin, its development in China and other countries and its advantages and disadvantages.Besides, the theory of dissolved air flotation is introduced from the point of view of thermodynamics, kinetics and the hydraulic characteristics of the flotation tank, which would be beneficial to the designers and the plant operators.At the end of this paper, the types of source water to which DAF process is more appropriate is discussed.

Key words: flotation, water supply treatment, low tunbidity water

摘要：

气浮净水技术已越来越多的应用于各类给水处理厂,作者对该技术的产生、国内外发展概况、优势及不足等方面进行了简要回顾与总结,特别是对其在给水处理领域的应用现状作了较为详细的介绍。此外,还简要介绍了气浮净水技术的理论体系(包括热力学理论、动力学理论、水力学特征及相应理论)及原水适应条件,以期对相关的科研、设计及管理工作者有一定借鉴。
