Application characteristics of biogas digesters:
(1) To provide cheap and high-quality fuel for a household of 3-5 in rural areas, a 63-103 biogas digester can be built. As long as the raw materials are sufficient, it can provide 9-11 months of cooking and lighting fuel per year. Due to the fact that biogas slurry can be used as pesticides, fertilizers, feed, etc., it can also be used as a resource to achieve the goal of conservation.
(2) Change the old living habits of farmers and improve the living environment in rural areas by building biogas digesters, toilets, and pigsties together, which is less likely to breed mosquitoes and has no odor. It will play an important role in eliminating infectious diseases such as schistosomiasis and hookworm disease. In addition, due to frequent human activities, a large amount of energy is consumed, and a large amount of straw and livestock manure are piled up outdoors, resulting in a large amount of carbon dioxide emissions and exacerbating the greenhouse effect. The use of biogas digesters can to some extent reduce the occurrence of the above problems.
(3) Promoting the development of ecological agriculture and animal husbandry, the waste from biogas digesters is biogas slurry and residue, which can be used as pesticide additives, fertilizers, feed, etc., greatly reducing the harm caused by fertilizers and pesticides, and promoting the production of green and pollution-free products.
