沼气发酵中的酸中毒!就是指由于料液酸化!导致发酵微生物中毒衰亡,最终表现为产气量降低或甲烷含量下降,所产气体不能燃烧。原因分析(1)发酵料液对沼气微生物具有抑制作用。在沼气发酵初期,由于产酸细菌繁殖快,产甲烷细菌繁殖慢,产酸细菌首先降解料液中的淀粉和糖类,产生大量的
Biogas fermentation in acidosis! Refers to the acidification of the feed liquid! Lead to microbial decline and death of fermentation, the final performance of gas production decreased or methane content decreased, the gas produced can not be burned. Reason analysis (1) fermentation liquid on biogas has inhibitory effect. In the early days of biogas fermentation, because of the rapid propagation of acid-producing bacteria and the slow propagation of methanogenic bacteria, acid-producing bacteria first degrade the starch and carbohydrates in the feedstock to produce a large amount of
