The pig farm bubble manure plug primarily utilizes the principles of water sealing and gravity sedimentation to achieve the collection and preliminary treatment of pig manure. Below is a detailed explanation of its specific principles:

Water Sealing Effect

A manure channel of a certain depth is installed beneath the floor of the pig pen, maintaining a certain water level to form a water seal. This prevents the odor from the manure channel from volatilizing upward into the pig pen, improving the air quality inside the pen and reducing the impact of harmful gases such as ammonia on the health and growth of the pigs.

Gravity Sedimentation

The feces and urine excreted by the pigs directly enter the manure channel, mixing with the water inside to form bubble manure. Due to the difference in density between feces and urine, under the influence of gravity, solid substances such as feces gradually settle to the bottom of the manure channel, while liquids like urine remain in the upper layer. After a period of accumulation, when the settled feces at the bottom reach a certain volume, they are discharged through specific sewage systems, such as pipes and valves, to external sewage treatment facilities or storage ponds for further processing.
