　　Gradually developed into reinforced concrete biogas digesters and enamel assembled tank biogas digesters. However, the high cost of traditional biogas digesters has deterred many farmers. Gradually developing to red mud biogas digesters, the cost of red film biogas digesters has been reduced compared to previous ones, but the performance is unsatisfactory, especially in terms of not being able to discharge slag. With the continuous introduction of technology, black film soft biogas digesters have quietly emerged. Black film biogas digesters, commonly known as covered lagoons, film covered biogas digesters, and geomembrane biogas digesters. Its biogas production principle is the same as that of the traditional biogas digester. It uses the advantages of HDPE membrane material in seepage prevention and leakage prevention to lay a layer of HDPE anti-seepage membrane in the excavated pit. According to the requirements of anaerobic fermentation process, the inlet and outlet, slag extraction pipe and biogas collection pipe are installed in the tank. The upper mouth of the pit is sealed with HDPE anti-seepage membrane, and the surrounding anchor ditches are fixed to form an overall anaerobic fermentation space. Through practical results, it has been proven that black film soft biogas digesters are more suitable for the pollution control needs of aquaculture farms. The principle is to use black film to absorb heat and improve fermentation efficiency. The construction cost of the tank is one tenth of that of a steel-concrete structure biogas tank and one-fifth of that of a red film biogas tank. Whether in terms of price, gas production, or usage effectiveness, biogas digesters from other processes are far ahead. Nowadays, black film soft biogas digesters have been widely popularized in Guangdong and Guangxi regions. The Guangdong Provincial Environmental Protection Department has recommended this process to breeding enterprises in Guangdong. As of the end of 2016, it is conservatively estimated that black film soft biogas digesters have already occupied one-third of the market in Guangdong region. This process gradually spread to Hunan, Jiangxi, Anhui, Hubei, Hebei and other places. Can this type of black film soft biogas digester be built in northern regions? Actual cases and usage effects have proven to be completely suitable. Dongnuo geotechnical material is the black film soft biogas digester. Hunan black film biogas digesters and Hebei black film biogas digesters are outstanding works of our company. At present, it has been operating stably for several years, producing stable biogas throughout the year. All biogas is used for power generation, which not only meets the needs of enterprise pollution control, but also has significant benefits for biogas power generation. Truly solved the bottleneck problem of traditional biogas digesters with only input and no output.

　　Laiwu Jinde Geotechnical Materials Co., Ltd. is located in the national geotechnical material production base--Laiwu, Jinan City, is a manufacturer of geosynthetic materials and waterproofing membranes, produced by the company;EVA\ECBTunnel composite waterproof board(glossy/Single hair surface/Double haired surface)，LDPE\HDPEGeomembrane (waterproof board),Composite geomembrane, needle punched non-woven geotextile, woven geotextile, bentonite waterproof blanket（GCL）Plastic drainage board (double-sided concave convex type, square type) grass grid, soft permeable pipe (spring blind pipe),PEPipe, plastic blind ditch (board), double (single) arm perforated corrugated pipe, geogrid (fiberglass steel plastic unidirectional and bidirectional), composite drainage network, geogrid room, soundproof felt and other products.

　　The black film of the biogas digester is made of high-density polyethylene, abbreviated as HDPE. Common specifications and thicknesses include 1.2mm, 1.5mm, and 2.0mm, and quality standards include urban construction standards and American standards. Black film for biogas digesters is a waterproof and barrier material based on high molecular weight polymers

　　The width and thickness specifications are complete. 2. It has excellent resistance to environmental stress cracking and chemical corrosion. 3. Excellent chemical corrosion resistance. 4. It has a wide range of operating temperatures and a long service life. 5. Used for landfill sites, tailings storage sites, channel anti-seepage, dam anti-seepage, and subway engineering, etc

　　Biogas digesters, also known as "fully enclosed anaerobic ponds", are currently an indispensable part of biogas production equipment in many breeding farms. The construction of anaerobic ponds is determined by the detailed situation of pig farms and other projects, and excavation and pond construction are necessary.

　　The black film biogas digester can integrate anaerobic fermentation and gas storage. Due to the comprehensive closure of the anaerobic pond, the organic matter in the biogas digester can effectively degrade the COD and BOD concentrations in the sewage, and through microbial fermentation, 80% -90% of the organic matter can be degraded, thereby producing biogas. The biogas is further converted into electricity, and the biogas residue can also be made into organic fertilizer. The volume of biogas digesters required for pig farms is related to the scale of the farm, the type of biogas digester used, the hydraulic retention period, etc., and can be calculated using the formula "biogas digester volume (unit: cubic meter)=average daily discharge (unit: ton) x hydraulic retention period (unit: day)". The hydraulic retention period specifically refers to the number of days sewage remains in the biogas digester. The hydraulic retention period of black film biogas digesters is at least one month and can last up to six months.

　　The Hefei Fengqun Pig Farm, which supplies black film biogas digesters from our factory, has a total of 2400 sows in stock and an annual output of 26000 pigs. At present, a 24000 cubic meter black film biogas digester has been built, which looks like a vegetable greenhouse in appearance, but the material of the black film is very strong, and people can stand on it without any problem.
