Methane (biogas)
The methane is some organic matter (for example reject and so on straw, weed, leaf, person livestock excrement) under the certain temperature, the humidity, the acidity condition, the isolation air (for example with methane-generating pit), the ignitable gas which (fermentation) proces after the microorganism function. The methane is the gas mixture, in which contains methane 60 ~ 70%, in addition also includes the carbon dioxide, the hydrogen sulfide, the nitrogen and the carbon monoxide and so on. It includes the few hydrogen sulfide, therefore slightly brings the fetid odor. The fermentation is the complex biochemistry change, some many microorganisms participation. The response approximately divides two stages: (1) microorganism's complex organic matter in carbohydrate, the fat, the protein degrades the simple matter, like the preliminary fatty acid, is mellow, the aldehyde, the carbon dioxide, the ammonia, the hydrogen and the hydrogen sulfide and so on. (2) by the methane mold mushroom spawn's function, causes some simple matter to turn the methane.
Must normally proce the methane, must for the microorganism creation good condition, enable it to survive, the reproction. The methane-generating pit must conform to the many kinds of conditions. First, the methane-generating pit must be airtight. The organic matter ferments the methane, is the many kinds of 厌氧菌 active result, therefore must create a 厌氧菌 active the oxygen deficit environment. When makes the methane-generating pit must pay attention to the isolation air, air-tight, does not seep. Next, in the methane-generating pit must maintain 20 ~ 40 ℃, because usually proces being mad rate under this kind of temperature to be highest. Third, the methane-generating pit must have the sufficient nutrient. The microorganism must survive, the reproction, must absorb the nutrient from the fermentation matter. In the methane-generating pit fermentation raw material, the person livestock excrement can provide the nitrogen element, crops' cellulose and so on straw can provide the carbon element. Fourth, the fermentation raw material must contain the right amount water, generally requests the methane-generating pit in the fermentation raw material to contain water about 80%, excessively are many or the too few all to proces is mad disadvantageously. Fifth, methane-generating pit pH value general control in 7 ~ 8.5.
