Problems solved by technology

[0005] The present invention aims to solve the above problems, and provides a preparation method of a soil conditioner based on garden green waste and livestock and poultry manure, which can overcome the defects that garden green waste and livestock and poultry manure cannot be easily processed and utilized. Carry out joint disposal and cooperate with the deployment of external sources to prepare a soil improver product that can improve the green land. On the one hand, it can reduce the pollution of waste to the environment and the economic cost of waste disposal; on the other hand, it can be used rationally Waste resources can be converted into soil improvers, which can improve the physical and chemical properties of green land soil after use, increase land production capacity, and reduce the adverse impact of large-scale use of chemical fertilizers on land

preparation example Construction

[0025] The preparation method of the soil conditioner based on landscaping green waste and livestock and poultry manure, comprises the following steps,

[0026] S1: Use a pulverizer to pulverize the mixed material of garden green waste by using the pressure roller hammer mill process. After the primary pulverization, the length of the primary material is not more than 5cm, and the diameter is not more than 2cm, and the pulverized product is screened; The final small particle size waste is 1-2cm in length and 0.5-1cm in diameter. Collect the small particle size green waste materials that meet the particle size requirements for later use, and the screened large particle size green waste is subjected to secondary crushing and screening until it meets the requirements. Particle size requirements;

[0027] S2: Use dehydration and drying equipment to dry livestock and poultry manure until the moisture content is below 20%. The dehydration and drying equipment can be a belt filter pr...

Embodiment 1

[0033] Collect landscaping waste, including 3000kg of thick branches and 1000kg of trimmed branches and leaves, pulverize through a hammer mill, and then sieve through an automatic screening machine with a screen size of 2cm. The obtained green waste with small particle size For standby, the large particle size green waste material is subjected to secondary crushing until the particle size meets the requirements;

[0034] Collect 12 tons of wet pig manure and 3 tons of wet chicken manure, and carry out drying and dehydration through a belt filter press dehydrator. 0.3cm-0.5cm;

[0035] The landscaping waste and livestock and poultry manure are transported to the screw mixing equipment for mixing. During the process, 21kg of aerobic fermentation bacteria and 40kg of corn starch are added to fully mix the materials and then add a certain amount of water to make the water content of the final material The rate is controlled at 65%, and the carbon-nitrogen ratio is controlled at ...

Embodiment 2

[0046] Collect landscaping waste, including 1500kg of thick branches and leaves, residual flowers, and 500kg of grass clippings, pulverize through a hammer mill, and then sieve through an automatic screening machine with a sieve particle size of 2cm. The obtained small particle size green The waste material is used for standby, and the green waste material with large particle size is crushed for the second time until the particle size meets the requirements;

[0047] Collect 6 tons of wet pig manure and 1.5 tons of wet chicken manure, and carry out drying and dehydration through a belt filter press dehydrator. The moisture content is controlled at 15%-18%. 0.2cm-0.4cm;

[0048] The landscaping waste and livestock and poultry manure are transported to the screw mixing equipment for mixing. During the process, 11kg of aerobic fermentation bacteria and 22kg of corn starch are added to fully mix the materials and then add a certain amount of water to make the water content of the ...

Abstract

The invention belongs to the field of fertilizer processing, and particularly relates to a preparation method of a soil conditioner based on garden green waste and livestock and poultry manure, which comprises the following steps: adding dried and crushed livestock and poultry manure, aerobic fermentation biological bacteria, starch and water into crushed and screened green waste, and fully and uniformly mixing; conveying the uniformly mixed materials to a fermentation field, and carrying out aerobic fermentation; after fermentation, drying in the sun to obtain secondary fine powder; taking 50-100 parts by weight of the secondary fine powder product, 1-3 parts by weight of urea, 1-2 parts by weight of a calcium magnesium phosphate fertilizer, 1-2 parts by weight of potassium chloride and 4-10 parts by weight of a water-retaining agent, and fully and uniformly mixing through mixing equipment, and obtaining the soil conditioner. By adding the exogenous additive, the composting process is promoted, the quality of a compost product is improved, the compost product is converted into a soil conditioner product to be applied to the field of soil improvement, and finally a circular economy closed loop is formed; the mode is low in one-time investment and low in production condition requirement; and the product has obvious effects on improving the soil structure and improving the water-retaining and fertilizer-retaining capabilities of the soil.

Description

technical field [0001] The invention belongs to the field of fertilizer processing, and relates to a method for preparing a soil conditioner from organic solid waste, in particular to a method for preparing a soil conditioner based on garden green waste and livestock manure. Background technique [0002] With the acceleration of urbanization, the area of ​​urban green space (municipal greening, residential greening, road greening, etc.) is also increasing, and the amount of green waste (twigs, leaves, residual flowers, grass clippings, etc.) produced every year is also increasing. many. For a long time, these landscaping green wastes are often regarded as solid wastes, and the usual disposal methods are landfill or incineration, which not only increases the cost of government waste disposal, wastes precious land resources, pollutes the environment, but also causes The waste of biomass energy such as garden waste is eliminated. In fact, garden waste contains a certain amoun...
