近年来,由于农村经济的发展和沼气综合利用的开展,农民对办沼气的要求有所改变。现在普遍感到“远、大、深”沼气池管理不便,出料困难,不适应需要。因此,各地多提倡建造8—10立方米的池子,一些地方还试验2—4立方米沼气池。农村户用沼气地的容积究竟多大为好?目前尚无统一认识,仍然是我们沼气科技战线探索和急待解决的—个课题。根据沼气常温发酵原理和农村各方面的实际情况,我们认为除了少数养殖专业户外,一般农户沼气池容积以4—5立方米为宜。这既便于管理,又能得到充分利
In recent years, due to the development of rural economy and the comprehensive utilization of biogas, the requirements of farmers for managing biogas have changed. Now generally felt “far, big, deep” digester management inconvenience, discharge difficulties, not suited to the need. Therefore, more than 8-10 cubic meters of ponds are advocated around the world and 2-4 cubic meters of digesters are also tested in some places. How big is the volume of biogas in rural areas? There is no unified understanding so far, and it is still an issue to be explored and urgently solved for our biogas science and technology front. According to the principle of biogas fermentation at room temperature and the actual conditions in all aspects of rural areas, we think that in addition to a small number of outdoor farming professional, the average volume of biogas digesters for farmers is 4-5 cubic meters. This is both manageable and profitable
