一、选用优质发酵原料为了保证沼气池启动和发酵有充足且稳定的发酵原料,在投料前,需要选择有机营养含量丰富的牛粪、猪粪、羊粪和马粪做启动的发酵原料。不要单独用鸡粪、人粪和绿豆渣或红薯渣、土豆渣,因为这类原料在沼气细菌少的情况下,料液容易酸化,导致发酵不能正常进行。 First, the selection of high-quality fermentation materials In order to ensure the start-up and fermentation of biogas digesters have sufficient and stable fermentation of raw materials, in the feed before the need to choose organic nutrient-rich cow dung, pig manure, sheep manure and horse manure to start the fermentation of raw materials. Do not use chicken manure alone, manure and green bean residue or sweet potato residue, potato residue, because such raw materials in the case of biogas bacteria less, the liquid easily acidified, resulting in the fermentation can not be normal.
