沼气“病态池”有二种情况,一种是由于池子漏气漏水产生故障;另一种是发酵代谢反常产生的故障。前者是宏观现象,对池子进行检查维修即可达到正常运转。后者为微观现象,为肉眼所不可见,需进行微生物和生化分析查明原因,从管理技术上加以改进使发酵恢复正常。本文仅介绍渗漏“病态池”的检查与维修。 Biogas “sick pool” There are two kinds of situations, one is due to the pool leakage leaks produce failure; the other is abnormal fermentation metabolism failure. The former is a macro phenomenon, the pool can be checked and repaired to achieve normal operation. The latter is a microscopic phenomenon, which is invisible to the naked eye. Microbiological and biochemical analyzes are required to identify the cause and the management techniques are improved to make the fermentation return to normal. This article describes only the leakage of “sick pool” inspection and maintenance.
