NOVELTY - Processing pig manure by using earthworm comprises e.g. constructing an earthworm biological bed by excavating a deep ditch around a quadrate ground, where a base surface of the earthworm biological treatment bed is constructed on the quadrate, transversely stacking an earthworm living matrix on the base surface, dividing into large and small rows based on stack interval, inoculating earthworms on earthworm living matrix, and covering a sun-shading net, performing anaerobic curing treatment on pig manure by placing the pig manure on open container, adding water to the container, and stirring.    USE - The method is useful for processing pig manure by using earthworm.    ADVANTAGE - The method is safe and ecofriendly, do not produce odor, prevents the problem of easy production of fly larvae during the conventional fermentation and stack overturn process, earthworm escape and death; has high clearing-up efficiency; and increases the quantity of the daily consumption of pig manure up to 2-3 times of the mass of the earthworms.    DETAILED DESCRIPTION - Processing pig manure by using earthworm comprises (i) constructing an earthworm biological bed by excavating a deep ditch around a quadrate ground, where a base surface of the earthworm biological treatment bed is constructed on the quadrate, transversely stacking an earthworm living matrix on the base surface, dividing into large and small rows based on the stack interval, inoculating earthworms (0.5- 1.5 kg/m2) on the earthworm living matrix, and covering a sun-shading net; (ii) performing anaerobic curing treatment on the pig manure by placing the pig manure on an open container, adding water to the container, and completely stirring until the pig manure turns to be black brown so that the pig manure has an anaerobic fermentation; and (iii) adding the cured pig manure of thickness 2-5cm on the long stack of the earthworm biological bed, where the material is added at once when 60-70% of the pig manure is cleared up, and repeating the above steps.
