Can not put raw material of digester

In a biogas digester, bacteria, such as methane, poison when they come into contact with harmful substances, lighter people stop breeding, and heavy ones die, causing the biogas digester to stop producing gas. Therefore, do not put the following harmful substances into the pool: various highly toxic pesticides, especially organic bactericides, antibiotics, insect repellents, etc.; heavy metal compounds, industrial waste water and salts containing toxic substances; newly eradicated poultry manure Sprayed crops stems and leaves of pesticides; various kinds of plants that can be used as pesticides such as bitterskin vines, tree fruits (leaves), peach leaves, thyme, sesame, etc.; spicy foods such as onion, garlic, pepper, leeks Radish; various types of disinfectant (84 disinfectant), calcium carbide, detergent, laundry water. None of the above substances can enter the biogas tank. It is forbidden to put phosphorus-containing organic raw materials into the pool, such as rapeseed cakes, cottonseed cakes, and phosphate fertilizers (such as superphosphate, phosphate rock powder, calcium magnesium phosphate fertilizer, etc.). Because this substance under the conditions of absolute anaerobic, it will produce highly toxic gas such as phosphine, causing people to die of poisoning.
