固体有机废弃物厌氧发酵装置研究进展

Research progress of anaerobic fermentation equipment on solid organic waste

文章在调查分析现有厌氧发酵设备的基础上,从我国高寒地区实际生产需要出发,提出了开发高效厌氧发酵设备的基本思路,主要是:产酸阶段和产甲烷阶段设备独立设置;产甲烷阶段采用厌氧滤器和三相分离器有机组合应用;采取有效的污泥回流和全程菌群富集技术以及有效的节能保温措施;加强自动控制使设备高效稳定运行等。

This article on the base of investigating and analyzing existing anaerobic fermentation equipment, applying combination of AF and UASB in methanogenic phase; adopting efficient sludge inverse flowing equipment and the technique of flora enrichment, and efficient method of saving energy and thermal retardation; adopting autocontrol which could make the equipment run efficiently and stably.
