１结构设计升环流复合沼气池结构如图１所示。该池包括升流间、环流间、均布孔等主要部分。２技术要点（１）采用升、环流二级发酵工艺．原料经过升流间作第一级上流式厌氧发酵后，再经过环流间作第二级推流式厌氧发酵．料液流程远，滞流期长，发酵充分，消化较彻底。（２...
A structural design Lumped circulation compound digester structure shown in Figure 1. The pool includes the upflow, circulation, uniform holes and other major parts. 2 technical points (1) using liter, circulating secondary fermentation process. The raw material is subjected to the first-stage up-flow anaerobic fermentation after the ascending flow and then the second-stage push-flow anaerobic fermentation through the circulation. Material flow far, long stagnation period, full fermentation, digestion more thoroughly. (2 ...
