The organic fertilizer fermentation composting cover is based on the e-PTFE microporous membrane: the core equipment of the e-PTFE microporous membrane capping system is the capping fabric that covers the organic waste (livestock and poultry manure, municipal sludge, domestic garbage, kitchen waste, etc.). The cover fabric is made of e-PTFE microporous membrane composite substrate, which is compounded in the middle of two layers of solid substrate fabric. e-PTFE microporous membrane is uniformly distributed with 0.1μm~0.4μm aperture microporous, and the cover substrate fabric has the characteristics of UV and friction resistance. Sealing livestock and poultry manure for high-temperature aerobic fermentation with the cover fabric can prevent the wind and rain to avoid the influence of bad weather, and at the same time, it can let the carbon dioxide gas and water vapor produced in the process of treatment to be discharged quickly. The water permeability of the microporous membrane affects the change of moisture in the treatment process, not only the material is too wet, but also to retain sufficient moisture for the degradation of the material.
The e-PTFE microporous membrane has a certain insulating effect and pressurizing effect, which can help the system to maintain the temperature, so that the oxygen concentration and temperature in the heap are evenly distributed, which is conducive to the whole heap are to achieve the temperature conditions to kill pathogens.
The micropores on the e-PTFE microporous membrane are an effective physical barrier to dust, aerosols and microorganisms, preventing them from spreading outward. During the fermentation process, the inner surface of the membrane generates a film of condensed water; most of the odorous substances in the off-gas, such as ammonia, hydrogen sulfide, volatile organic compounds (VOCs), etc., are dissolved in the water film, and then droplets of water droplets fall back to the pile, where they continue to be decomposed by microorganisms. 99% or more, so it can protect the site from sterilization and deodorization, making the environment healthier.
