一、备足优质新料沼气出料前,必须备好新料,采用富氮原料。入冬前后,采用含“富氮有机原料”的鲜猪粪(或鲜牛粪、鲜羊粪)作发酵原料,不要用含“贫氮有机原料”的干麦草、玉米秸秆等作发酵原料,目的是缩小碳氮比,加快甲烷菌的繁殖,使之多产气。一般8~10 First, prepare high-quality new material Biogas before discharge, must be prepared new material, the use of nitrogen-rich raw materials. Before and after winter, using fresh pig manure (or fresh cow dung, fresh sheep manure) containing “nitrogen-rich organic raw materials ” as raw material for fermentation, do not use dry grass, corn stalks, etc. containing For fermentation of raw materials, the purpose is to reduce the ratio of carbon and nitrogen to speed up the propagation of methane bacteria, so that more gas. Generally 8 to 10
