辽宁省能源研究所于82年4月在营口市老边公社及盖县白果农场,利用红泥增强塑料膜建造家用沼气池,深受农民欢迎。这种沼气池的优点是:结构简单,造价低廉(建一个四立方米的沼气池只需花60～70元,如果包括塑料池体、导管及炉具则需要80元),产气高,占地少。用红泥增强塑料膜建家用沼气池可分全塑、半塑两种,它们的修建方法大致相同。一、建造全塑沼气池:先挖一个直径为2.3米、深0.8米的土坑,坑边上嵌装预制的水泥水封圈(内壁2.3米、外壁2.7米、高0.25米、厚0.04米,槽宽0.15米),见(图一),再将膜厚为0.36±0.02毫米、直径大于2.3米、深1.3米制成桶形放入坑内,把这块膜上边卷在内圈上,并贴在外圈内壁上,然后就 Liaoning Institute of Energy in April 82 in Yingkou City, Laobian commune and Gaixia Ginkgo Farm, the use of red mud enhanced plastic film to build household biogas digesters, welcomed by farmers. The digester has the advantages of simple structure and low cost (it takes only 60 to 70 yuan to build a four cubic meter biogas digester, and 80 yuan to build a plastic cell body, conduits and stoves), high gas production, Small footprint. Reinforced plastic film with red mud built household digesters can be divided into plastic, semi-plastic two, roughly the same method of their construction. First, the construction of plastic biogas digesters: first dig a diameter of 2.3 meters, 0.8 meters deep pit, embedded in the edge prefabricated cement seal (wall 2.3 meters, the outer wall of 2.7 meters, 0.25 meters high, 0.04 meters thick , Groove width of 0.15 m), see (Figure 1), and then the film thickness of 0.36 ± 0.02 mm, diameter greater than 2.3 m, 1.3 m deep into the barrel made into the pit, the film on the inner roll in the inner ring, And attached to the inner wall of the outer ring, and then
