Problems solved by technology

[0003] However, unlike other garbage, biomass solid waste is composed of cellulose, hemicellulose, lignin and nitrogen-containing organic matter, and has the characteristics of high water content. Direct combustion not only pollutes the atmospheric environment, but also has low calorific value, which is not easy to use ; If it is landfilled, although it can be degraded by the soil's own ability, the degradation time is long and the utilization rate is low. The anaerobic effect produced by the landfill makes the feces ferment and produces odorous gas, which seriously damages the soil nutrient structure. At the same time, it breeds mosquitoes and flies, bacteria, viruses, etc., which poses a serious threat to human health; if it is piled up for a long time, it will not only occupy the land, but also as time goes by, the piled objects will ferment by themselves, producing stench and leachate, which seriously damages the surrounding environment , have a great impact on people's normal life

Abstract

The invention discloses a method for breeding earthworms through biomass solid waste. The method includes the steps of (1) mixing the biomass solid waste with livestock and poultry feces in a breeding device after the biomass solid waste is smashed, (2) reacting the mixture for 5 days-9 days at 50 DEG C-90 DEG C to obtain earthworm breeding matrixes, (3) placing the earthworms in the earthworm breeding matrixes, and adjusting the pH value, the humidity and the temperature to carry out breeding, (4) after the earthworms are bred for 18 days-22 days, harvesting the earthworms when the weights of the earthworms range from 400 milligrams to 500 milligrams, and the density of the earthworms ranges from 15,000 to 20,000 per square meter, and (5) scraping the breeding matrixes on the upper layer after the earthworms are bred for three days, and adding the new breeding matrixes, wherein the scraped breeding matrixes are earthworm feces organic fertilizers. The method has the advantages that the biomass solid waste is decomposed and converted in the bodies of the earthworms through feeding habits and intermediate propagation and metabolism of the earthworms, the high-quality earthworms and high-quality earthworm feces are obtained, the biomass solid waste is recycled, land resources are saved, the resource use efficiency is improved, and the remarkable economic benefits are obtained.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for cultivating earthworms by using biomass solid waste. Background technique [0002] Biomass solid waste mainly includes landscaping waste, straw agricultural waste, sugarcane waste, poultry manure, etc. Specifically, it mainly includes branches, leaves, grass, corn stalks, corn cobs, corn husks, wheat straw, rice straw , cotton stalks, rice straw, wheat straw, cane pith, bagasse, cow dung, pig manure, chicken manure and other excrement of livestock. It is characterized by containing a large amount of comprehensive cellulose (hemicellulose and cellulose) and nitrogenous substances. At present, the annual output of landscaping waste in my country is about 100 million tons, the annual output of straw is about 1 billion tons, the annual output of bagasse and sugarcane pith is about 50 million tons, and the annual output of poultry manure is about 3.5 bi...
