biogas digester

biogas digester advantage

biogas digester is used to ferment and produce biogas.Organic matter in an anaerobic environment, in a certain temperature, humidity, ph conditions, through microbial fermentation for use, the production of a flammable gas.Because the gas was first found in marshes, lakes and ponds, it is called biogas.

Biogas digester has the following advantages: one is the high removal rate of organic matter, COD removal rate of more than 78%, BOD removal rate of more than 82% : two is to prevent sludge floating, and through multi-stage filtration, the water is neutral, good health and environmental protection effect, can basically reach the standard: three is to get a certain quality gas - biogas.But biogas digester also has problems, the water chroma is generally on the high side, and nh3-n removal rate is not easy to reach the standard.

Biogas digester has fixed arch cover of water pressure pool, large open cover of water pressure pool, hanging pipe of water pressure pool, meander distribution of water pressure pool, top water pressure pool, floating cap pool, semi-plastic pool, plastic pool and tank pool.Although a variety of forms, but overall up by water pressure biogas digester, floating mask biogas digester, semi-plastic biogas digester and tank biogas digester four basic types of changes formed.

Biogas digester construction, the choice of foundation is very important, which is related to the quality of the pool and pool life problems, must be seriously treated.As the biogas digester is buried in the underground building, so, and soil quality is very good or bad relationship.

Load determination is a very important link in biogas digester design.So - called load, it is to point to the weight that place bears on unidirectional area.If the load is determined to be too large, the design of biogas digester structure section is bound to be too large, resulting in too much material, resulting in waste;If the load is determined too small, the design strength is insufficient, it is easy to cause the pool fracture.

biogas digester construction

With the economic development and social progress of our country, the life of urban residents has been further improved, but there are still many problems in the life of rural residents.In order to build a well-off society in an all-round way, it is necessary to build a new socialist countryside.This requires the development of rural ecological agricultural production mode, improve the rural environment, increase the income of farmers grand goals.

Comprehensive utilization of biogas digester is an important way to change the rural environment.Construction of a biogas digester can be used for about 20 years, comprehensive utilization of biogas digester can not only save energy, improve and protect the environment, but also save fertilizer and pesticides, improve crop yield and quality, promote and drive the development of the breeding industry and many other benefits.

Provide cheap and high-quality fuel for rural families of 3 to 5 people, build a 6 cubic to 10 cubic meters of biogas digester, as long as sufficient raw materials, a year can provide 9 to 11 months of cooking and lighting fuel problems.As biogas slurry can be used as pesticide, fertilizer and feed, it can also be used as a resource to achieve the purpose of saving.
