沼气是一种可燃气体。由于最初人们发现于湖泊沼泽中,故称之谓沼气。现在人们已了解它是各类有机质在厌氧条件下,经各类微生物分解而产生的一种气体,故又称之谓生物气。 据最新研究成果表明,有机物产沼气是通过3大类菌群的作用而获得的,各类有机物:作物秸秆、麦秸、稻草、花生棵及主要的人畜禽粪便等,都可作发酵原料。当他们进入厌氧发酵池内开始酸解,产酸阶段的代谢菌群有:纤维素分解菌以及脂肪分解菌等,属第一大类,由产氢产乙酚细菌将丙酸,预酸、醇类等物质分解产生氢和乙酸,属第二大类;最后由产甲烷菌分解乙酸形成甲烷和二氧化碳,甲烷菌利用氢还原二氧化 Biogas is a combustible gas. Because initially found in lakes and swamps, it is called biogas. Now people have learned it is all kinds of organic matter in anaerobic conditions, by a variety of microbial decomposition and a gas, it is also known as biogas. According to the latest research results, biogas generated from organic matter is obtained through the action of three major types of bacteria. All kinds of organic matter such as crop stalks, wheat straw, straw, peanut trees and the main human and animal manure can be used as fermentation raw materials. When they enter the anaerobic fermentation tank began to acidolysis, the acid-producing stage of the metabolic flora are: cellulolytic bacteria and lipolytic bacteria, which is the first category, by the hydrogen production of phenol-producing bacteria propionic acid, pre-acid, Alcohols and other substances to produce hydrogen and acetic acid decomposition, is the second largest category; the final methanogenic methanogenic decomposition of methane and carbon dioxide, methanogenic reduction of hydrogen using hydrogen dioxide
