我国的养殖业迅速发展的同时也对空气、水体、土壤等环境造成污染,但粪便中的各种营养成分决定其可以进行综合利用,包括通过堆肥生产肥料,通过青贮、脱水干燥、生物处理等手段生产饲料,进行厌氧发酵生产沼气等。提出了畜禽粪便的资源化技术发展的前景仍以综合利用为发展方向。

Air, water and soil pollution is brought about with the development of animal husbandry in our country, but due to various nutrition components in feces of livestock and poultry, the excrement can be comprehensive utilized. The livestock feces can be used as fertilizer via composting, as feed via ensiling, dehydration drying or biological treatment; it also can be used to produce marsh gas by anaerobic fermentation, It points out that the prospect for utilizing the livestock feces will still follow the way of comprehensive utilization.
