生物质项目厌氧发酵工艺选型研究

Study on Selection of Anaerobic Fermentation Process for Biomass Project

厌氧消化工程作为生物质资源综合开发利用的手段和方法之一,越来越受到人们的重视。本文分析了我国厌氧消化工程发展现状,介绍了各种厌氧发酵方法的技术特点,并对国内常用的厌氧发酵消化器的技术参数及优缺点进行对比。以某生物质项目为例,通过在该生物质项目中对比湿法、干法厌氧发酵技术,以及高温、中温及常温厌氧发酵的主要特点,确定项目的厌氧发酵方式,为生物质厌氧发酵项目的推广应用提供经验参考。

As one of the means and methods for the comprehensive development and utilization of biomass resources,anaerobic digestion engineering has attracted more and more attention.This paper analyzed the development status of anaerobic digestion engineering in China,introduced the technical characteristics of various anaerobic fermentation methods,and compared the technical parameters,advantages and disadvantages of commonly used anaerobic digestion digesters in China.Taking a biomass project as an example,through the comparison of wet and dry anaerobic fermentation technology in the biomass project,and the main characteristics of high temperature,medium temperature and normal temperature anaerobic fermentation,the anaerobic fermentation mode of the project was determined,which provideh experience reference for the promotion and application of biomass anaerobic fermentation project.
