Biogas is a colorless and special odor combustible mixture gas. Biogas contains hydrogen sulfide, so it has the odor of rotten eggs. The reason why biogas can be burned is that biogas contains methane, hydrogen, carbon monoxide, hydrogen sulfide and other combustible gases. Below the biogas desulfurization factory for everyone to popularize some basic conditions of biogas fermentation, I hope to help you!

沼气是沼气微生物在厌氧条件下发酵、分解有机物而产生的一种可燃性气体。这种气体是在沼泽地里发现，所以称为沼气。其成分的比例随发酵原料的种类、相对数量、发酵条件及发酵时间的差异而不同。

Biogas is a kind of flammable gas produced by biogas microorganisms fermenting and decomposing organic matter under anaerobic conditions. This gas is found in marshes, so it is called biogas. The proportion of its components varies with the variety of fermentation materials, relative quantity, fermentation conditions and fermentation time.

人工制取沼气必须具有三个基本条件

There are three basic conditions for the production of biogas by hand

1、沼气池：是与空气隔绝的厌氧装置，保证沼气微生物生活在严格的厌氧环境中，同时便于收集和贮存沼气。

1. Biogas digester: an anaerobic device isolated from air to ensure that biogas microorganisms live in a strict anaerobic environment, while facilitating the collection and storage of biogas.

2、沼气微生物：它们是沼气的生产者。沼气微生物是一些种类繁多、习性各异的专性和兼性的细菌，存在于沼气池、粪坑、池塘的料液残渣、粪便、污泥和牛粪中。对这类物质，我们称之为接种物，是沼气池首次投料的必备原料。

2. Biogas microorganisms: They are the producers of biogas. Biogas microorganisms are a variety of specific and facultative bacteria with different habits. They exist in biogas digesters, dung pits, sludge and cow dung. For this kind of material, we call it inoculum, which is the necessary raw material for the first feeding of biogas digester.

3、发酵原料：能够被沼气微生物分解利用的有机物。农村的沼气发酵原料主要是人、畜、禽粪便，农作物的秸秆、青饲料、杂草等。

3. Fermentation raw materials: Organic substances that can be decomposed and utilized by biogas microorganisms. The main raw materials for biogas fermentation in rural areas are human, livestock, poultry manure, crop straw, green fodder, weeds and so on.
