Problems solved by technology

However, the time required for the decomposition and fermentation of the above-mentioned microorganisms is as long as 2 to 4 months, and a large-scale factory building is required for decomposition and fermentation.
In addition, incompletely decomposed organic fertilizers may cause harm to crops (such as: burning seedlings, spreading plant pathogenic bacteria, insect eggs, and weed seeds), harm to the environment (such as: releasing carbon dioxide and toxic gases, producing stench), Impact on public health (e.g. spreading of viruses and / or bacteria, breeding of mosquitoes)
[0004] In view of the fact that the above-mentioned traditional organic fertilizer manufacturing methods are not only time-consuming and may have the risk of not fully decomposing, there is an urgent need to improve the manufacturing methods of organic fertilizers

Embodiment 1

[0034] Example 1 Rapid Manufacturing of Organic Fertilizers

[0035] 98 kg of biological waste and 2 kg of microwave absorbing material were put into a mixer and stirred evenly to form a mixture. In this embodiment, the biological waste can optionally be single or mixed types of chicken manure, duck manure, goose manure, pig manure, cow manure, sheep manure, horse manure and other fresh poultry manure or marsh slag, and the water content of the biological waste is about 50% to 90% (w / w). The microwave absorbing substance can optionally be single or multi-type mixed silicon carbide, rubber, coke, graphite, carbon powder, iron oxide, ferric oxide, zinc oxide, molybdenum sulfide, zirconium dioxide, barium titanate, Magnesium carbonate, and the particle size of the microwave absorbing substance is not greater than 1mm.

[0036] Put the biological waste into a tunnel microwave reactor. The tunnel microwave reactor comprises a tunnel microwave reaction chamber and a conveyor belt...

Embodiment 2

[0046] Example 2 Decomposition Judgment of Organic Fertilizer - Filter Paper Diffusion Graphics Determination Method

[0047] The organic fertilizer made in Example 1 (using chicken manure, pig manure, and biogas residue as raw materials respectively) was used as the experimental group samples, and untreated chicken manure, pig manure, and biogas residue were used as the control group samples. The steps of the filter paper diffusion imaging assay are as follows;

[0048] A. Put each sample into an oven, set the temperature at 60°C, and place it for 1 day after drying;

[0049] B. Take Sartorius 392 125mm filter paper, put it in a glass dish, then soak it with 0.5% (w / v) silver nitrate (AgNO3) solution in the fume hood, and place it in an oven to avoid light and air dry;

[0050] C, the fertilizer sample after step A is dried, weighs 10g and packs into a 250ml jar, and adds 1% NaOH of 100ml, shakes at room temperature for 5 hours and extracts;

[0051] D. Get 40ml of the fert...

Embodiment 3

[0055] Example 3 Decomposition Judgment of Organic Fertilizer-Solvita Decomposition Degree Detection Method

[0056] The organic fertilizer made in Example 1 (using chicken manure, pig manure, and biogas residue as raw materials respectively) was used as the experimental group samples, and untreated chicken manure, pig manure, and biogas residue were used as the control group samples. The steps of the Solvita maturity test method are as follows:

[0057] A. Adjust the humidity of each sample to 70%, and let it stand overnight;

[0058] B. Take 50g of the samples adjusted in step A, and put them into the test bottles respectively, so that the fertilizer is in the filling line, cover but not lock the upper cover, and let the air in the bottle balance for 1 hour;

[0059] C. Insert the carbon dioxide detection sheet and the ammonia detection sheet into the fertilizer sample in step B respectively, fasten the upper cover, and act for 4 hours;

[0060] D. Take out the test piece ...

Abstract

The invention discloses a method for rapidly preparing an organic fertilizer. The method can be used for quickly preparing biological wastes like livestock manure and / or biogas residues into an organic fertilizer, and comprises the following steps of: providing a tunnel type microwave reactor, which comprises a tunnel type microwave reaction chamber and a conveying belt, wherein the tunnel type microwave reaction chamber is provided with a feed port and a discharge port, and the conveying belt penetrates through the feed port, the tunnel type microwave reaction chamber and the discharge port;placing a biological waste on the conveying belt, feeding the biological waste into the tunnel type microwave reaction chamber through the feed port to be heated by a microwave, maintaining the temperature in the tunnel type microwave reaction chamber at 70-95DEG C, and controlling the time for the biological waste to enter the feed port and leave the discharge port at 5-60min; and collecting thebiological waste subjected to microwave treatment to obtain an organic fertilizer; by means of the method, the high-quality organic fertilizer can be rapidly manufactured, the efficiency is higher, the requirement for the site space is small, foul smells are not likely to be generated, pollution cannot be caused, the manufactured organic fertilizer product is completely sterilized, the biologicalsafety is high, and the defects in the prior art can be overcome.

Description

technical field [0001] The invention relates to a method for rapidly producing organic fertilizers, in particular to a method for rapidly processing biological wastes using microwaves to produce organic fertilizers. Background technique [0002] The whole world has been growing day by day to the demand of animal husbandry products in recent ten years, and one of the major problems that the vigorous development of animal husbandry brings is a large amount of poultry manure waste (a kind of biological waste). Improper handling of poultry manure waste will lead to serious problems such as environmental pollution, eutrophication of groundwater bodies and rivers, climate warming, and soil degradation. [0003] The use of organic fertilizers to replace chemical fertilizers in agricultural transformation has gradually attracted attention. At present, most organic fertilizers come from raw materials such as poultry manure, residual branches, rice husks, and kitchen waste. Microorgan...
