随着农村能源建设的健康稳步发展,农村家用沼气池在农村已普遍得到推广和应用。但由于历史原因,许多老式沼气池在用了一段时间后出现不好使用或完全不能使用的情况,给今后沼气建设带来极不利的影响。因此,如何改造好老式沼气池是目前摆在我们面前的一个重要课题。下面就有关技术问题谈谈看法。一、改造老式池应从池子本身改。许多老式池,由于其本身在工艺流程和发酵工艺等方面存在着一些问题,因而造成年久失修不能使用,如有的沼气池只有发酵装置没有气箱;有的有气箱又因太小影响产气;有的只建了沼气池却没搞“三结合”等等,使这些池子处于瘫痪或半瘫痪状态,对于这些沼气池的改造,应从以下几个方面考虑:
With the healthy and steady development of rural energy construction, household digesters in rural areas have been widely popularized and applied in rural areas. Due to historical reasons, however, many older digesters have been in use for a period of time and have become totally unserviceable, which has a detrimental impact on future biogas construction. Therefore, how to reconstruct the old-style digester is an important issue that we are facing now. Here to talk about the technical issues. First, the transformation of the old pool should be changed from the pool itself. Many old-fashioned pools, due to their own processes and fermentation processes, there are some problems, resulting in disrepair can not be used, if some biogas digester fermentation tank only, there are air boxes and too little impact Gas production; some built only biogas digesters but did not engage in “three combined” and so on, so that these pools in paralyzed or semi-paralyzed state, for the transformation of these biogas digesters should be considered from the following aspects:
