How to do the biogas in rural areas
No blasting, pool. No blasting around the methane tank to avoid the vibration of the pool. Biogas tank in the water pressure test and feed, can not be dumped too fierce, especially when the water into the inlet and outlet of the baffle, but also to slow down, so as to avoid the sudden increase in gas pressure inside the pool, causing the pool wall rupture. When the discharge of methane tank, but also to prevent too fast, too fierce, so as not to produce negative pressure, destroy the pool wall. Methane tank cannot bear gravity, especially in the pool built pigsty, will not hold wooden support in the pool, to avoid damaging the tank body, resulting in leakage. We should always observe the change of the pressure gauge, when the gas pool pool gas pool, strong pressure, want to use gas or gas to prevent the gas pool cover up bad box; such as being open, to immediately destroy biogas pool near the fireworks, so as to avoid fire. No poison. When the bacteria are exposed to harmful substances, they will be poisoned, and the light will stop breeding, and the dead will cause the biogas digester to stop the production of gas. Therefore, don't put the harmful substances into the pool: all kinds of highly toxic pesticides, industrial wastewater; just a sterile animal manure; washing soap, washing powder and water; just sprayed crop stems and leaves of pesticides; soybean cake, peanut cake, cottonseed cake, bone meal and calcium carbide; phosphate rock phosphates; Liu Shuye neem leaf, castor leaf, tobacco stem, wormwood can do all kinds of soil pesticide plants.
Rural household biogas digesters into raw materials and strains, after the start, only to strengthen the daily management, in order to make the biogas pool enduring good real estate gas, gas production. If methane stable gas or gas production is low, can not guarantee the need to boil water for cooking three meals a day and evening light, so be sure to put a digester livingorganism view, cannot be used as a garbage pit, what things to dumping, to make the biogas tank stable gas production and gas production of foot.
Good water, good concentration. The fermentation raw materials in the methane tank must contain the right amount of water, which is conducive to the normal life of biogas bacteria and methane production. Because of the absorption of nutrients, the excretion of waste and the survival and reproduction of biogas bacteria, there is a need for appropriate water, too much or too little water is not conducive to the activities of biogas and biogas production. If the amount of water is too much, the content of dry matter in the fermentation liquid is less, and the gas production per unit volume is small; if the water quantity is too small, the fermentation liquid is too strong, and the organic acid is easy to accumulate. According to the experimental research and practical experience, it is proved that the suitable concentration of fermentation material is 6%~12%. In this range, due to the high temperature in summer, the rapid decomposition of raw materials, the concentration can be slightly lower in winter due to low temperature, slow decomposition of raw materials, the concentration should be slightly higher.
