沼气池的效益 ENERGY VALUE OF HOUSEHOLD BIOGAS REACTORS
北京市荣各庄村单一式沼气池,旺气期约3个月,;弱气期4个月左右,。全年共产沼气约160立方米。【1】
北京市留民营生态村每年使用70吨煤为沼气工程加温,生产了相当于200吨煤的炊事能力的沼气。【2】
户用沼气的建立对农村自然环境的影响不明显,但对农村居住环境、生活环境的改善有明显有利的影响。【3】
Household Biogas Reactors individually has the energy value to the households. However, it is not because of it energy value, but because of the ecological advantage. Biogas is cleaner than any fuels in the rural area.
For example, a household biogas reactor in Beijing can generate m3 biogas per day per m3 of reactor for 3 warmest months and m3 of biogas per day per m3 of reactor for other 4 moderate warm months.
Household biogas helps big improvement of indoor environment.

沼气池的能源效益? ENERGY VALUE OF HOUSEHOLD BIOGAS REACTORS?
能源替代效益存在显著差异性。不同的能源消费者对沼气的接受度从大到小依次为:电力-液化气-煤炭和薪柴和秸秆消费者。
沼气在作为薪柴和秸秆的替代能源时,其经济效益是负值,这主要是由于环境影响并不为消费者所感知。户用沼气利用对使用薪柴和秸秆的低收入农村居民并不存在经济吸引力。【1】
Even for the household biogas reactor, it is less attractive for the farmers if just think about the energy value because the farmers can use crop residues which is free. The ecology benefits are not evidently concerned by the rural residents at present.
However if enough knowledge is extended to the farmers, they are more and more care about the health.
