Progress and Application of High-load Anaerobic Bioreactor

概述了厌氧消化的基本原理,包括厌氧消化过程理论与厌氧消化的主要影响因素。简单介绍了厌氧生物反应器的发展历史,重点介绍了典型高负荷厌氧生物反应器(上流式厌氧污泥床,厌氧膨胀颗粒污泥床和内循环式反应器)的特点和运行机制,及其应用情况。通过以上概述指出高负荷厌氧生物反应器存在的问题和缺陷。最后,提出高负荷厌氧生物反应器今后的研究重点应该放在如何提高反应器效率上。

Basic principle of anaerobic digestion is simply reviewed. It includes anaerobic digestion theory and the main influencing factors. The development history of anaerobic digesters is summarized,and the characters,the running mechanisms,and application of some typically high-load reactors,such as Upflow Anaerobic Sludge Blanket （UASB）,anaerobic expanded granular sludge bed and IC anaerobic reactor,are especially introduced. In summing up,the problems and the defects of the high-load anaerobic reactors are put forward. Finally,it is also pointed out that the future study of anaerobic digester should focus on how to raise the reactors＇ efficiency.
