摘要
通过培育形成了"奶牛养殖→牛粪沼气发电→牛粪沼渣生产有机肥→牛粪沼液生产叶面肥"牛粪综合循环利用新产业链,每立方牛粪综合经济效益由原先58元提高到317元,提高了446.6%,实现了经济和生态效益双丰收,为天水市养殖场粪污的治理和开发利用提供了非常有用的参考依据。
A new industrial chain of cow dung comprehensive recycling usage was fostered and formed,which was dairy breeding → biogas power generation → biogas residue organic fertilizer production →biogas slurry foliar fertilizer production, increasing the overall economic efficiency to 317 RMB compared with the former 58 RMB per cubic, which increased by 446.6~.
