流态研究推动下的高效厌氧生物反应器的发展

The Development of High-rate Anaerobic Apparatus Promoted By the Study of Flow Pattern of Such Reactors

近年来以膨胀颗粒污泥床反应器、内循环厌氧反应器等为代表的第三代高效厌氧反应器以其独特的技术优势在各种废水处理领域得到了广泛的应用。从反应器内流动状态研究的角度,分析并总结了几种典型的高效厌氧反应器的流态特征,探讨及回顾了当代高效厌氧反应器设计思路及其发展历史,指出高效厌氧反应器的流态研究成为进行新型厌氧反应器开发与应用的理论基础与研究重点之一。

Owing to its inherent priority in application, the third -generation high -rate anaerobic reactors （such as EGSB and IC reactors） have become one of the most popular designs for the biological treatment of effluents in recent years. In this paper, the development history and design method of those apparatus were systematically summarized by analyzing the characteristics of the flow pattern of those reactors. It was pointed out that the flow pattern research has important implications for the design and operation of such high - rate reactors.
