Listen to people say that pig manure with biogas digesters to deal with, I would like to know how to build biogas digesters, what is the principle
A selection of high quality raw materials, and composting treatmentBiogas fermentation raw material is not only the material basis of biogas production, but also the source of nutrients for microbial survival. In order to ensure the biogas fermentation and start fermentation of raw materials sufficient and stable, so that the tank fermentation material is not easy in the crust, and easy to achieve, easy management, high gas production rate to the need to carefully select the good start of the first fermentation pool of raw materials.All kinds of organic substances, such as wastewater and animal manure, crop straw, agricultural and sideline products processing residua and sewage etc. can biogas fermentation raw material. Biogas fermentation microorganisms mainly from the fermentation of carbon and nitrogen elements, as well as hydrogen, sulfur, phosphorus and other nutrients. Carbon can provide energy for biogas microbes, nitrogen constitutes cells, and the appropriate ratio of carbon to nitrogen is 25:1 ~ 30:1. If the carbon is too much, it is easy to cause the acidification of the fermentation liquid, such as too much nitrogen, which is easy to cause the fermentation liquid to ferment (partial alkali).
After the household biogas digester is completed, the fermentation start and daily management work is good or bad, which has great influence on the gas production rate. "Three points to build, in charge of the seven" is the vast number of biogas technology workers summed up the valuable experience in practice. It has been proved that the biogas digester with the same structure is scientific, reasonable and meticulous. Therefore, it is necessary to grasp the biogas digesters start fermentation and daily management of technical essentials, so that its premature gas, gas production, gas production.The first section of the rapid start of biogas digestersWhether it is the newly built biogas digesters or reloading after restarting, input from the fermentation of raw materials and inoculum to the digester, biogas digesters to produce biogas can stably, this process is known as biogas fermentation start. The structure of the same biogas digesters, fermentation start each link to deal with properly, its gas production and the use of different results. For example, in the summer, start the digester smoothly, seal tank after 3 ~ 5 days to start the ignition; biogas pool is not smooth, a pool after 10 days or even longer time can use the ignition, some even have to start fermentation, ingredients. Therefore, it is very important to have a good grasp of every link in the fermentation of biogas digester.
Five, is likely to produce acid, high concentration, easy to acid production in summer! Test with PH test paper!I do not know how much of your gas, how much water, how many cubic? Is not the exhaust gas, air pressure?If it is good, there is too much acid to be added! In front of the stove mouth, ignition try, smell is not a sour smell! Add pure pig urine!
Methane tank sealing problem.Two, the raw material is not used disinfectant or pig antibiotics.Three, there is no detergent or household disinfection of things into the pool.Four, temperature. But from the current temperature considerations, should not be a temperature problem. But it is possible that the concentration is too high to be diluted with water! Should you join the pig urine, I do not know whether to join the water?
