Problems solved by technology

[0007] The method of the present invention is aimed at the existing organic waste decomposing method-the composting technology has high material preparation requirements, produces odor, insect fly problems, low composting technology application rate and low composting due to low humus quality and low content of composting products. When the land utilization rate of the product is low, it provides a method of decomposing organic matter. This method adds activated soil minerals and humus soil containing soil microorganisms and their metabolites to organic waste without adjusting the material composition. , to produce high-quality humus, and the process does not produce secondary pollution environmental problems such as odor, insects and flies

Embodiment 1

[0031] This example is a case of liquid organic waste, the organic waste is 500L of human feces and urine, the organic content is 15000mg / L, the added activated soil mineral is 3kg of andesite pumice powder, and the added humus containing soil microorganisms The soil is general swamp soil 75kg (poor quality). The above-mentioned materials were put into the mixing tank and stirred slowly for 24 hours, and then decomposed for 25 days. During the decomposing period, the slow stirring was carried out for 30 minutes every day. During the decomposing period, no odor and insects and flies were produced. The decomposed material is subjected to solid-liquid separation to obtain high-quality humus material, its respiration rate is less than 200mg / kg·h, and the seed germination index reaches 72%, which meets the agricultural requirements. It shows that the method of the present invention can obtain high-quality humic substances.

Embodiment 2

[0033] The organic waste of this example is solid, and described organic waste is chicken manure 500kg with moisture content 90%, and the soil mineral of the activation of adding is andesite pumice powder 5kg, and the humus soil that adds contains soil microorganism is fertile Natural swamp soil 50kg (high quality). The above materials were mixed and stirred for 2 hours, the temperature reached 48°C, and then decomposed for 20 days. During the decomposing period, the piles were turned once a week, and the piles were turned twice in total. Finally, 120kg of products containing high-quality humus were obtained. During the decomposing period, no odor and insects and flies are produced, the respiration rate of the decomposed product is less than 200mg / kg·h, and the seed germination index reaches 82%, which meets the agricultural requirements. It shows that the method of the present invention can obtain high-quality humic substances.

Abstract

The invention provides an organic matter humification method, and belongs to the technical field of stabilization and recycling of organic waste. According to the method, activated soil minerals and humus soil containing soil microorganisms and metabolites thereof are added into solid or liquid organic waste, and the soil microorganisms are utilized to humify organic matters to obtain high-quality artificial humus close to natural humus. The organic waste can be effectively utilized to manufacture high-quality humus to be returned to soil, the fertilizer, water and soil retention capacity of the soil is improved, and the natural soil inherent substance circulation process is manually supplemented.

Description

technical field [0001] The invention relates to a method for humifying organic matter, and belongs to the technical field of organic waste stabilization and resource utilization. Background technique [0002] Natural humus is a complex and relatively stable macromolecular organic colloidal substance formed by soil organic matter through the action of soil microorganisms. It is generally black or dark brown. It is the main component of soil organic matter and has the ability to release nitrogen, phosphorus, potassium, and sulfur to the soil. Calcium and other essential elements of animals and plants, trace elements and nutrients, improve soil water retention capacity, porosity and aeration, sterilization and disinfection, etc., are the key substances for soil water conservation, soil and fertilizer protection. [0003] With the rapid development of the economy and the acceleration of the urbanization process, the urban population has increased sharply, and the cities and town...
