　　The "low cost, high efficiency" black film biogas digester process adopts a new type of anti-seepage membrane technology, making the entire storage process more scientific, concise, and significantly lower in cost and engineering expenses than traditional waterproof materials. After actual calculations, it has been found that using this storage process can save about 50% of costs compared to traditional storage processes.

　　7. Fast construction speed: on-site excavation and film covering can be carried out, with a short installation and construction period. Single pool film covering can be completed in 3-5 days. Adopting hot melt welding, the weld strength is high, the construction is convenient, fast and safe.

　　8. Diversity of choices: unrestricted use in all regions of the country, unrestricted storage areas within the venue, and unrestricted seasons; There are three modes to choose from, and domestic customer service can choose according to the actual needs of the pig farm.

　　The development of biogas digesters closely related to the aquaculture industry has gone through a process from underground brick and concrete structure biogas digesters to 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.

　　We are a production base for lotus pond special film, lotus pond special anti-seepage film, lotus pond anti-seepage film, aquaculture film, and sea cucumber aquaculture film. We warmly welcome your visit!

　　Lotus root cultivation geomembrane is an anti-seepage material composed of PE film as the substrate and geotextile composite. Its anti-seepage performance mainly depends on the PE film. The PE film used for anti-seepage membrane applications mainly includes polyvinyl chloride, polyethylene, and EVA (ethylene/vinyl acetate copolymer). They are a high molecular weight chemical flexible material with a small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance. The main mechanism is to use the impermeability of plastic film to block the leakage channel of the earth dam, and to withstand water pressure and adapt to dam deformation with its high tensile strength and elongation;
