沼气是一种清洁能源,现在得到了广泛的应用!下面沼气脱硫设备厂家的小编给大家介绍一下沼气工程制取沼气需要具备的一些条件,希望对大家有所帮助!
Biogas is a kind of clean energy, which has been widely used now. Below the small manufacturer of biogas desulfurization equipment to introduce to you the biogas project to produce biogas needs to have some conditions, I hope to help you!
1.严格的厌氧环境沼气发酵微生物包括产酸菌和产甲烷菌两大类,它们都是厌氧细菌,尤其是产生甲烷的甲烷菌对氧特别敏感。它们不能在有氧的环境中生存,哪怕微量的氧存在,也会使发酵受阻。因此,建造一个不漏气、不漏水的密闭沼气池,是人工制取沼气的关键。
1. Biogas fermentation microorganisms in strict anaerobic environment include acid-producing bacteria and methanogens, which are both anaerobic bacteria, especially methanogens which produce methane are particularly sensitive to oxygen. They do not survive in an aerobic environment, and even trace amounts of oxygen can hinder fermentation. Therefore, the construction of a sealed biogas digester without leaking gas and water is the key to manually produce biogas.
2.足够和优良的接种物接种物是沼气发酵所需要的含有大量微生物的厌氧活性污泥,也称菌种。只有具备足够优良的接种物才能保证沼气发酵高效运行。农村户用沼气池的接种物一般来源于老沼气池的沼渣(沼液)、阴沟的污泥、粪坑底部的沉渣等。接种物用量一般占总发酵液的30%左右。
2. Sufficient and excellent inoculants are anaerobic activated sludge containing a large number of microorganisms, also known as strains, which is needed for biogas fermentation. Only with good enough inoculum can biogas fermentation run efficiently. The inoculants of rural household biogas digesters generally come from the sludge of old biogas digesters (biogas slurry), sewage sludge, sediment at the bottom of the dung pit, etc. Inoculants generally account for about 30% of the total fermentation broth.

3.必要的发酵温度沼气发酵菌种在8℃~60℃范围内都能发酵产气,并且温度越高,发酵越活跃,产沼气越多。因此,作为常温发酵的农村户用沼气池,应尽量使其发酵温度保持在8℃以上。
3. The necessary fermentation temperature of biogas fermentation bacteria can ferment to produce gas in the range of 8 60 C, and the higher the temperature, the more active the fermentation, the more biogas is produced. Therefore, as a rural household biogas digester with normal temperature fermentation, the fermentation temperature should be kept above 8 C as far as possible.
4.适宜的酸碱度在沼气发酵过程中,沼气菌适宜在中性或微碱性的环境中繁殖。发酵液的ph值控制在6.8~7.5为宜。如低于或高于此值,沼气发酵就会缓慢,甚至不能正常进行。
4. Suitable acidity and alkalinity in biogas fermentation process, biogas bacteria are suitable for breeding in neutral or slightly alkaline environment. It is advisable to control the pH value of fermentation broth at 6.8-7.5. If this value is lower or higher, biogas fermentation will be slow or even not normal.
