Difference between biogas digester and septic tank. Is there a digester without a septic tank?
Biogas digesters are generally used to produce gas, energy use. Septic tanks are used to treat domestic sewage.Water can not be poured into a methane tank (such as laundry). The life of those dishes, such as water also can not produce any gas.So, I suggest you do it separately.Biogas digesters are generally dedicated. More than domestic sewage, biogas digesters are likely to produce gas. The loss outweighs the gain。
The difference is that the biogas digester is airtight. With a methane tank can not septic tank. However, the liquid can not be put into the biogas slurry tank, such as household disinfectant, washing powder water and so on. Some inconvenient. In addition, there is no increase in the north of the pool heat preservation may not be used.
It is said that the principle of biogas digesters is through anaerobic fermentation, the use of methane bacteria to produce combustible methane, the main raw materials are animal manure, plant debris, etc.. Biogas digester has the advantages of improving the production and living environment in rural areas, providing energy and so on. In China's rural areas to promote household biogas based, but also in the development of large and medium sized farms biogas project. Plan in 11th Five-Year to promote the number of households accounted for 70% of the pool built in the city for the purification of biogas digesters, septic tanks, each district must be built. The main function is the preliminary treatment of fecal sewage.The septic tank consists of three pools connected by a tube, the middle manure is the use of Unicom, anaerobic fermentation, and the proportion of fecal parasite eggs over the middle than the general mixture proportion and easy precipitation principle, feces in the pool after fermentation for more than 30 days of decomposition, followed by the 1 middle fecal fluid flow to the pool pool 3 in order to achieve, pathogens or parasites kill fecal egg deposition and intestinal, liquid manure third pool become high-quality fertilizer. Almost every building is equipped with septic tanks.
