Description

Black film fermentation tank

Technical Field

The utility model relates to the technical field of pig manure treatment equipment, in particular to a black film fermentation tank for biogas fermentation.

Background

When the pigsty is used, a pig can produce a lot of excrement in the pigsty, and the excrement is usually cleared by a cleaning person and then fermented to produce an organic fertilizer. However, these sewages contain a large amount of organic matters, and are very likely to cause great environmental pollution without treatment. The most common method for utilizing the excrement is to put the excrement into a fermentation tank to ferment so as to generate the methane. Most of fermentation tanks used at present are tank type fermentation, the structure is complex, the energy consumption is high, the volume is too small, the cost is high, the utilization rate of biogas is low, and the fermentation tanks are not suitable for large-capacity treatment of excrement in farms.
