During fiberboard production, a lignin sludge byproduct is necessarily produced. The lignin sludge contains more than 96% of wood fine fibers. The wood fine fiber is organic and can be used as food for Lumbricus. And because the procedure of high-temperature cooking is included in the production process of the fiberboard, the lignin sludge does not contain faecal coliform and ascarid eggs, and is a thermalized soft food loved by earthworms. Through detection, the lignin sludge does not contain mercury, the arsenic content is 3.4mg/kg, the lead content is 12.4mg/kg, the cadmium content is 2.8mg/kg, the chromium content is 26.8mg/kg, and the heavy metal content is in the range suitable for breeding earthworms. Therefore, the lignin sludge can be directly used as earthworm feed without a fermentation process or any other ingredients. And (5) a detection report of the lignin sludge attached later.
As shown in fig. 1, a method for breeding earthworms by using lignin sludge comprises the following steps: lignin sludge generated in the manufacturing process of the fiberboard is directly paved in the earthworm cultivation greenhouse by the feeding crawler after the cement is separated.
