Background technique

Manure is one of the most common and disgusting garbage, and the daily discharge is huge, especially in livestock farms that raise various livestock such as pigs and cattle. When a large amount of livestock excrement is discharged or left alone, it will cause soil pollution and water pollution such as groundwater or rivers, thereby causing serious environmental pollution. In order to prevent such pollution, environmental pollution can be prevented by post-processing livestock manure (livestock excrement and urine). The current post-processing method for livestock manure and the like is to treat part of the animal manure at the public livestock wastewater treatment plant operated by the local self-government government. , very few are processed by farmers themselves (when the number of livestock is small and the discharge of livestock manure is small, it can be applied to fertilizers and other purposes through post-treatment processes such as fermentation), but most of the livestock manure is thrown into the ocean.
