大办沼气是解决燃料,解放妇女劳动力;增积肥料,提高肥效,促进农业生产,改善卫生条件,保护人体健康的好措施,深受广大群众欢迎。我们在大办沼气过程中发现,由于粪便发酵后,大量的粪渣集结形成一层厚厚的粪膜,盖住了水面,必须经常打破粪膜,才能使沼气进入贮气箱。我们通过实践,自制了一种简易粪膜隔离器,造价低、效果好、使用方便,现介绍如下。隔离器的构造:用一段较大、较老的竹子,长短以从池底的石墩到池顶盖板下为宜。竹子下段(从石墩到沼气池进出粪 Largely engaged in biogas to solve the fuel, the liberation of women’s labor force; increase fertilizer, improve fertilizer efficiency, promote agricultural production, improve health conditions, good measures to protect human health, welcomed by the general public. During the process of large-scale biogas treatment, we found that as a result of the excrement fermentation, a large amount of manure accumulated to form a thick layer of fecal film and covered the surface of the water. Therefore, it was necessary to frequently break the manure so that the biogas could enter the gas storage tank. Through practice, we made a simple fecal membrane isolator, low cost, good effect, easy to use, are introduced below. Isolator structure: With a section of older, older bamboo, the length from the bottom of the stone pier to the top of the pool is appropriate. The lower part of bamboo (from the stone pier to digester into and out of manure
