畜禽粪便的资源化利用

Utilization of livestock′s dejection as biogas origin

随着社会主义新农村建设的启动和实施,为实现村容整洁,清洁生产和节约能源,黑龙江省加大了农村废弃物资源化的利用强度,通过以畜禽粪便为原料,进行庭院式甚至工厂化沼气生产,为农村提供新能源,同时沼气生产过程中产生的沼液和沼渣经过处理后可作为农作物肥料和一些家畜及鱼类饲料进行再利用,在保护生态环境、美化家园、发展生态农业等方面发挥重要作用,促进黑龙江省的循环经济发展。

With the startup and execution of new socialistic countryside construct in Heilongjiang Pro- vince, the transition from castoff to resource was strengthened in the countryside aiming at neat appearance of the countryside, clean production and saving energy. People produced biogas and provided the countryside with new energy by means of turning livestock＇s dejection into resource, composting of plant and animal＇s leavings in courtyard or even in factory. The liquid and solid residue in the biogas production could be reused as fertilizer for crops or food for animal after pretreatment, which played an important role in protecting eco-environment, beautifying homestead and developing ecological agriculture and so on. And it was also propitious to accelerate the development of recycled economy in Heilongjiang Province.
