5.5 Application Case of Harmless Treatment Technology
of Livestock Manure
The equipment for harmless treatment of livestock manure is a high-efficiency biological bed-type processor for urine (Fig. 5.5). The equipment integrates bioengineering
technologies, like rapid biological fermentation of enzyme bacteria, optimization of
high-efficient microbial fermentation environment, the deodorization by microorganisms and recovery and utilization of solar and thermal energy. By using straws,
weeds and rice hulls generally seen in villages as bedding materials, biological heat
produced through aerobic fermentation is used for evaporating urine moisture and
retaining effective nutrients. Based on this, the bad smell of wastes is removed and
these including worm eggs, infectious microbe, virus and weed seeds are inactivated
in 24–48 h. The treated wastes belong to high-quality farmyard manure and are rich
in beneficial bacteria and bio-enzyme, which realize comprehensive treatment and
resourceful utilization of planting and breeding wastes in villages. The equipment
