Description

Technical Field

[0001] The invention relates to the technical field of bioreactors, and in particular to an intelligent earthworm bioreactor. Background Art

[0002] The earthworm bioreactor is a technology that treats organic waste, sewage or wastewater based on the natural transformation process of earthworms and the microbial communities in their digestive system. This reactor system uses the decomposition ability of earthworms to treat organic waste and convert it into valuable by-products, such as nutrient-rich organic fertilizer. Earthworms themselves are highly efficient decomposers of organic waste in nature. They ingest organic matter in the soil, digest and decompose it, and ultimately convert it into nutrient-rich earthworm castings. Through this environmentally friendly and green process, earthworms are able to effectively decompose complex organic matter in waste into organic fertilizer that can be used in agriculture, forestry and other fields. Earthworm bioreactors have become an effective means of treating organic waste today due to their advantages such as low cost, high efficiency and environmental protection. However, earthworm bioreactors rely on earthworms as the core unit for waste treatment, and their processing speed and effect are greatly affected by the activity state of the earthworms. Existing earthworm bioreactors often use open containers to load waste and facilitate ventilation to avoid affecting the activity state of earthworms. However, open containers will cause the odor generated by the waste and the waste gas generated by decomposition to spread into the air, affecting the surrounding environment and operators. In addition, simply using open containers for waste loading will result in poor ventilation of the waste accumulated at the bottom of the container and low decomposition efficiency. If the waste is turned and stirred manually, it will bring additional burden to the operator. Therefore, in the field of bioreactor technology, it is necessary to propose an earthworm bioreactor that is more convenient, intelligent and efficient for waste treatment. Summary of the invention
