The development of film-covered aerobic composting technology in my country is mainly divided into two stages: technology introduction and independent research and development and promotion. In 2010, the Zhujiajiao Wastewater Treatment Plant in Shanghai, my country, introduced the first functional membrane-covered aerobic composting system in China for composting sludge. Since then, Qinghai, Tibet, Xiamen and other places in my country have also introduced this technology.
A large number of pig farms, chicken farms, and cattle farms still dry and dry solid manure on site for fermentation. Turning fermentation or spending huge sums of money to purchase fermentation tank equipment, but still cannot meet the current requirements. The smell of drying on the spot is too great, turning requires building a factory, and the investment and operation cost of fermentation tanks is too high. Faced with this demand environment, Teflon Compost Membrane ManufacturerMolecular membrane composting technology came into being.
Biological fermentation membrane is a waterproof and breathable membrane, mainly composed of expanded polytetrafluoroethylene (ePTFE). That is, ePTFE composite fabric is a film-coated composite fabric composed of an ePTFE film and a fabric with low yarn count, high wear resistance, sun resistance, and tear resistance through a lamination process. While protecting the core film, it also has a great impact on the later accumulation. Good insulation and protection.
Nano film composting is a composting method that does not require turning the pile. It can save a lot of labor and energy consumption during operation. After being covered by the membrane, The aeration at the bottom can provide the microorganisms in the pile with enough oxygen needed for fermentation. As the temperature rises, odorous macromolecules such as ammonia and hydrogen sulfide escape, but the microporous structure of the nanomembrane can block the moisture from the outside. It can enter, but small water molecules can pass through, but large molecules such as ammonia and hydrogen sulfide cannot pass through. The water vapor dissolved on the surface of the membrane finally returns to the stack and is used by microorganisms. In this way, the water is removed. , without the odor effect, the decomposed agricultural fertilizer is produced, which can be directly returned to the fields, or directly sold to organic fertilizer factories for processing and production of commercial organic fertilizers.
At present, the ePTFE compost covering film independently developed by Teflon composting membrane manufacturer is the core material of nanomembrane intelligent composting technology. The membrane is composed of an e-PTFE membrane and a substrate, which is sandwiched between two strong substrate membranes. The e-PTFE membrane is evenly distributed with micropores with a pore size of 0.2 μm, and the base membrane is corrosion-resistant.
PTFE membrane technology has always been the core of Teflon composting membrane manufacturer‘s business, in biopharmaceuticals, equipment, food and beverages, It plays an indispensable role in cutting-edge fields such as semiconductor manufacturing and communications. Teflon Compost Membrane Manufacturer The pore-forming capacity ranges from 0.1μm to 1μm, providing fine filtration, bacteria and virus removal, waterproofing, breathability, and sound transmission and other functional solutions.
