　　If the geomembrane for biogas digesters is not chosen properly, many hidden dangers may arise during later operation. According to requirements, the geomembrane for biogas digesters should be selected from environmentally friendly geomembranes, such as urban construction standard geomembranes. Urban construction standard geomembranes are produced through three-layer co extrusion using blow molding technology, with high strength and long service life. It is generally recommended to use geomembranes of 1.5 millimeters or more for the top film of biogas digesters in breeding farms, and 1.0 millimeter or 1.2 millimeter geomembranes for the bottom film and sedimentation tank as anti-seepage films; Another inexpensive material is made from recycled materials (waste materials) using a rolling process (coating). Coating, also known as cast film, is a non stretch, non oriented flat extruded film produced by rapid cooling of molten saliva. There are two types of drooling: single-layer drooling and multi-layer co extrusion drooling. Production of film coating: Firstly, the raw materials such as polymer particles, moisture-proof agents, colorants, carbon black, etc. are proportioned and stirred evenly before being fed into the material bin. Then, the polymer particles and other raw materials are heated and melted into a fluid state through an extruder, and the geotextile film is formed in the narrow slot of the mold head. After being cooled by a cooling roller with a cooling agent, it is formed and then cut into the width and length required by the customer before being packaged into rolls. Due to different manufacturing processes, the film material produced by this equipment looks shiny, but its molecular structure is compromised, which greatly reduces its service life. Generally used for bottom anti-seepage of geomembranes in biogas digesters. Nowadays, fish pond aquaculture often encounters situations such as long-term drought and low rainfall, which leads to a decrease in groundwater level and high permeability of fish pond soil, all of which can cause fish pond leakage. The service life is sufficient for the anti-seepage requirements of highway engineering.
