随着养殖业的迅速发展,畜禽粪便的排放量日益增大,这些粪便处置不当会对环境造成严重污染,同时也给畜牧场的环境卫生以及人类健康带来威胁[1]。目前国内规模猪场粪便处理方法除了沼气发酵和固液分离外,还有三段生态法和好氧微生物发酵法[2]。其中好氧微生物发酵法制作有机肥受到越来越多的关注,是依靠微生物的生物降解作用降解粪便中的有毒有害物质,同时利用产生的生物热杀灭粪便
With the rapid development of aquaculture, the excretion of livestock and poultry excrement is increasing. Improper disposal of these excrements can cause serious pollution to the environment, and threaten the environmental sanitation of livestock farms and human health [1]. At present, there are three sections of ecological methods and aerobic microbial fermentation in addition to biogas fermentation and solid-liquid separation in domestic pig farms [2]. Among them, the production of organic fertilizer by aerobic microbial fermentation method is receiving more and more attention, which is to degrade the toxic and harmful substances in the excrement by the biodegradation of microorganisms and to kill the excrement by utilizing the generated biological heat
