　　Black film biogas digester

　　Membrane biogas digester is an important part of biogas production equipment in many breeding farms nowadays. There are already many demonstration projects nationwide. This technology was introduced to China in 2003 and has been highly praised by many breeding farm owners. This process technology has a large gas production capacity, low cost, and can effectively degrade the concentration of COD and BOD in wastewater.

　　The biogas digester is excavated and constructed, with anti-seepage membrane laid at the bottom. The anti-seepage membrane has a good anti-seepage effect and will not pollute groundwater. The top is covered with black membrane for full sealing, significantly reducing odors and protecting the surrounding environment. Biogas can be converted into electricity to keep pig houses warm, provide lighting and cooking electricity for livestock farms, and be used as fertilizer for growing vegetables and fruits. Biogas residue can be directly discharged into fish ponds as feed.

　　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. Its characteristics

　　1. 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.
