Manufacture organic fertilizers, recycle nutrients in aquaculture water bodies and use bioenergy.
1. Make organic fertilizer: Mix eel droppings with other organic waste (such as crop straw, kitchen waste, etc.) for composting. After fermentation and decomposition, high-quality organic fertilizer can be obtained. fertilizer It can be used to fertilize farmland, gardens, fruit trees and other plants to provide nutrient supply and improve soil quality.
2. Recovery of nutrients from breeding water: During the breeding process of eels, eel feces release a large amount of nutrients. Timely recycling can reduce the pollution of the water body and can be treated by a reasonable water treatment system. Eel excrement is collected and processed as fertilizer or raw material.e first bioenergetics.
3. Bioenergy utilization: Organic matter in eel feces can be converted into bioenergy, such as biogas, biodiesel, etc. through fermentation and gasification technologies, which can reduce waste emissions and obtain a renewable energy supply.
