Description

Technical Field

[0001] The utility model relates to the technical field of earthworm breeding equipment, in particular to a three-dimensional earthworm breeding and waste treatment device. Background Art

[0002] Currently, waste treatment methods (such as sludge) mainly include landfill and incineration. Landfilling, on the one hand, is slow to degrade and pollutes surface and groundwater resources. On the other hand, it requires a large amount of land and has a significant impact on the environment. Incineration equipment is expensive to invest in and wastes resources due to its low calorific value. Earthworm farming is currently a preferred method for sludge treatment. Earthworms can convert insoluble organic matter in sludge into organic matter that can be used by microorganisms, increasing microbial activity and substrate utilization. The synergistic effect of earthworms and microorganisms can accelerate the decomposition of organic matter.

[0003] At present, earthworm composting sites are mainly open-air earthworm ground breeding beds or earthworm ground breeding beds or breeding ponds in ordinary greenhouses, which can easily cause leachate of biological composting raw materials such as sludge to cause secondary pollution to the soil and groundwater.
