当前,畜牧业向规模化生产方向发展,在带来经济效益的同时,畜禽排泄物的无序排放增加了环境成本,规模化养殖场周边环境日益恶化。利用沼气技术处理畜禽粪便污染,实现资源化综合利用,达到清洁生产的目的,保护农业生态环境,是农业可持续发展的保障。
At present, the development of livestock husbandry in the direction of large-scale production brings about economic benefits. Meanwhile, the disorderly discharge of livestock and poultry excrement increases the environmental costs and worsens the surrounding environment of large-scale farms. The use of biogas technology to deal with the pollution of livestock and poultry manure, to achieve comprehensive utilization of resources to achieve the purpose of cleaner production and protect the ecological environment of agriculture is the guarantee of sustainable agricultural development.
