建造一个好的沼气池是制取主物沼气的基础。目前我省各地建造沼气池方法很多,有的用三合土建池,有的用混凝土现浇薄壳建池,有的用水泥预制块建池,有的用砖石材料建池;池型上有圆球型、卵圆型、船型和方型等等。实践证明,建造沼气池必须因地制宜,因土而异,才能做到建一个,成功一个,并充分利用当地的原材料,降低建池成本。就家庭小沼气池的池型而言,圆球型、卵圆型比船型、方型的要好。这里向大家介绍的是适合于砂质土壤地区甚至有流砂、地下水位高都能应用的现浇混凝土薄壳 Building a good biogas digester is the basis of the main biogas system. At present, there are many ways to construct biogas digesters in various parts of our province. Some use Sanhe earth-built ponds, some use concrete cast-in-situ thin-shell built ponds, others use cement prefabricated blocks to build ponds, and some use masonry materials to build ponds; Ball type, oval type, ship type and square type and so on. Practice has proved that biogas digesters must be built according to local conditions, depending on the soil, in order to build one, a success, and make full use of local raw materials and reduce the cost of pool construction. On the family pool of small biogas digesters, spherical, oval than the ship, square is better. Here to tell you about is suitable for sandy soil areas and even flow sand, high water table can be applied to the cast-in-place concrete shell
