一、沼气池快速启动1、选用优质发酵原料用于启动的发酵原料要纯净,不能混入泥土、塑料袋等杂物。尽量采用优质的新鲜牛粪、猪粪、羊粪或马粪,切忌用鸡粪和人粪启动。2、调节碳、氮比选择含碳素较高的牛马粪要与含碳素较低的人畜粪便适当配合,适宜的碳氮比在20～30:1的范围内,才能满足沼气发酵条件。一般牛马粪、猪粪的碳氮比分别为24:1、13:1,用这些原料发酵快,周期短,人粪的碳氮比为2.9:1。
First, digester quick start 1, the selection of high-quality fermentation materials used to start the fermentation of raw materials to be pure, can not be mixed with dirt, plastic bags and other debris. Try to use high-quality fresh cow dung, pig manure, sheep manure or horse manure, avoid chicken manure and manure start. 2, the adjustment of carbon, nitrogen ratio Select cattle with higher carbon horse manure should be appropriate with low carbon manure and livestock appropriate carbon and nitrogen ratio in the 20 ~ 30: 1 range, to meet the biogas fermentation conditions. General cow manure, pig manure C and N ratios were 24: 1, 13: 1, with these fast-fermented raw materials, short cycle, manure C / N ratio of 2.9: 1.
