Method for hermetia illucens larva transformed chicken manures

Abstract

The present invention provides a method for hermetia illucens larva transformed chicken manures. The method comprises the following steps: (1) according to the parts by weight, 3-5 parts of chicken manures and 1 part of biomass accessory material are respectively taken, the taken materials are mixed evenly, and the mixture is flatly spread in a transforming tank to be cultured for 2-3 days; (2) according to the parts by weight, 8-10 parts of chicken manures and 1 part of biomass accessory material are respectively taken, the taken materials are mixed evenly, and the mixture is placed in the transforming tank in a dot-matrix way to be cultured for 2-3 days; (3) according to the parts by weight, 60-70 parts of chicken manures and 7 parts of biomass accessory materials are respectively taken, the taken materials are mixed evenly, and the mixture is placed in the transforming tank in the dot-matrix way to be cultured for 4-6 days; (4) according to the parts by weight, 10-15 parts of chicken manures and 3 parts of biomass accessory materials are respectively taken, the taken materials are mixed evenly, and the mixture is placed in the transforming tank in the dot-matrix way to be cultured for 3-4 days; and (5) the larvae and the chicken manure residues are separated. The method of treating the chicken manures is short in cycle, the feed ratio is simple, and in a larva transformation cycle, 1 ton of the chicken manures can produce 130-200 kg of fresh mature larvae, a chicken manure dry material reduction reaches 55%-60%, and the method solves the accumulation problems of the chicken manures.

Description

technical field [0001] The invention relates to a method for transforming chicken manure, in particular to a method for transforming chicken manure by bright-spotted flathorn larvae. Background technique [0002] With the increase of society's demand for eggs and chicken, the chicken industry has developed rapidly, and the amount of chicken manure that follows has also continued to rise. Chicken manure is rich in easily biodegradable organic matter, nutrients, and pathogenic bacteria. If it is not handled properly, it will become one of the main sources of pollution. [0003] At present, the treatment of chicken manure in my country mainly relies on traditional methods, such as: organic fertilizer (direct use, composting), feed (direct feeding or feeding after drying), energy conversion (direct combustion, biogas fermentation), these methods occupy land Large, long cycle, unstable quality, and low input-output rate, easy to produce secondary pollution.
