[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention. Example

[0020] See also Figure 1 A method for treating manure of antibiotic-free ecological pigs comprises the following steps: S1: Collect and pre-treat the manure of antibiotic-free ecological pigs to remove large particles of impurities; S2: Use mechanical separation or gravity sedimentation to separate the solid and liquid parts of manure; S3: Mixing the solid part of the manure with the bedding to form a preliminary fermentation matrix, and placing the formed fermentation matrix in a fermentation device; S4: introducing microbial strains into the fermentation matrix of the fermentation device; S5: Control the temperature, humidity and ventilation of the fermentation substrate to promote aerobic fermentation activities of microorganisms and convert manure into organic fertilizer.

[0021] Among them, the present invention provides a method for treating manure of antibiotic-free ecological pigs. Through a series of optimized processing steps and fermentation device design, large-particle impurities in manure are effectively removed, solid and liquid parts are separated, and they are converted into organic fertilizers by microbial fermentation. The fermentation device includes a fermentation box 1 and a magnetic oxygen supply ball 2, which can monitor and adjust the temperature and humidity of the fermentation matrix in real time to ensure the stability and efficiency of the fermentation process. The magnetic oxygen supply ball 2 has a unique structure and meets the aerobic fermentation requirements of Bacillus licheniformis by adsorbing and releasing oxygen, thereby improving the fermentation efficiency and the quality of organic fertilizers. By using rice husks, sawdust and wheat straw as bedding, the physical and chemical properties of the fermentation matrix are further optimized, ensuring the smooth progress of the fermentation process. This method is not only environmentally friendly and efficient, but also realizes the recycling of manure resources, with significant economic and environmental benefits.

[0022] The specific steps of pre-treatment of manure from antibiotic-free ecological pigs in S1 include: S11: Collect manure from antibiotic-free ecological pigs from farms; S12: Transport the collected manure to the treatment site, avoiding leakage and contamination during transportation; S13: Use a vibrating screen to remove large particles of impurities in the manure and then stir and mix to ensure that the particle size of the manure is uniform.

[0023] The specific steps of treating the liquid part of the separated manure in S2 include: S21: storing the separated liquid part in a liquid manure storage tank; S22: Anaerobic fermentation of liquid manure to remove harmful substances; S23: The liquid manure after anaerobic fermentation is treated in a biological filter to be further purified.

[0024] The material of the bedding in S3 includes any one or more of rice husk, sawdust and wheat straw.

[0025] Among them, rice husk is a by-product of rice processing, with a high fiber content and good air permeability. Rice husk can improve the physical structure of the fermentation matrix, increase its porosity, and help air circulation. Higher air permeability is conducive to the growth and reproduction of aerobic microorganisms and promotes the rapid decomposition of organic matter. The water absorption of rice husk helps to regulate the humidity of the fermentation matrix and prevent the matrix from being too moist and affecting the fermentation effect.

[0026] Sawdust is a by-product of wood processing. It is rich in organic carbon and has a high water absorption capacity. Sawdust can provide a rich carbon source, help balance the carbon-nitrogen ratio (C / N) of the fermentation matrix, and is a key factor in microbial metabolic activity. An appropriate C / N ratio can promote microbial activity and increase the degradation rate of organic matter. The water absorption of sawdust also helps maintain the appropriate humidity of the matrix to avoid being too dry or too wet.

[0027] Wheat straw can increase the volume and porosity of the fermentation matrix, improve the ventilation conditions of the matrix, and ensure that oxygen can fully enter the fermentation matrix. Good air permeability is essential for aerobic fermentation process and can promote aerobic respiration and metabolic activities of microorganisms. In addition, the water absorption capacity of wheat straw helps to regulate the humidity of the matrix and prevent the matrix from being too dry and affecting the fermentation effect.

[0028] See also Figure 2-4 The fermentation device in S3 includes: a fermentation box 1 and a magnetic oxygen supply ball 2, a bracket 11 is fixedly connected to the top of the fermentation box 1, and a temperature sensor and a humidity sensor are installed in the fermentation box 1, a rotary telescopic actuator 12 is installed at the bottom of the bracket 11, and a fixed disk 13 is fixedly connected to the output end of the rotary telescopic actuator 12, a plurality of uniformly distributed stirring rods 14 are fixedly connected to the bottom of the fixed disk 13, an electromagnet is installed in the fixed disk 13, and a heating rod is installed in the stirring rod 14; a plurality of magnetic oxygen supply balls 2 are arranged, and a plurality of magnetic oxygen supply balls 2 are arranged in the fermentation box 1.

[0029] A fixing rod 21 is installed inside the magnetic oxygen supply ball 2, and an adsorption ball 22 is installed outside the fixing rod 21. A plurality of evenly distributed supplementary release grooves 23 are provided on the magnetic oxygen supply ball 2. A plurality of evenly distributed elastic strips 24 are fixedly connected to the inner wall of the supplementary release groove 23. A sealing gasket 25 is fixedly connected to one end of the plurality of elastic strips 24, and the sealing gasket 25 abuts against the inner wall of the supplementary release groove 23.

[0030] A heat-conducting support frame 26 is fixedly connected to the inner wall of the supplementary release groove 23, and a feedback strip 29 is fixedly connected to the bottom end of the heat-conducting support frame 26 and one end of the sealing gasket 25 close to each other. A breathable and waterproof membrane 27 is installed on the inner wall of the supplementary release groove 23 and on the upper side of the heat-conducting support frame 26. A heat-conducting block 28 is embedded on the magnetic oxygen supply ball 2 and located on the outer surrounding area of ​​the supplementary release groove 23, and the heat-conducting block 28 is connected to the heat-conducting support frame 26.

[0031] The material of the adsorption ball 22 is set to be activated carbon material, and the material of the feedback strip 29 is set to be memory alloy material.

[0032] The solid feces is placed in the fermentation box 1 for fermentation. Since Bacillus licheniformis is an aerobic bacterium, sufficient oxygen is required during the fermentation process. A temperature sensor and a humidity sensor are installed in the fermentation box 1 to monitor the temperature and humidity of the fermentation substrate in real time.

[0033] When the temperature sensor detects that the temperature in the fermentation box 1 exceeds the set threshold range, the rotary telescopic actuator 12 on the top of the fermentation box 1 is started, and the output end of the rotary telescopic actuator 12 is fixedly connected to a fixed disk 13, and the bottom end of the fixed disk 13 is fixedly connected to a plurality of evenly distributed stirring rods 14, and a heating rod is installed in the stirring rod 14 for supplementing heat when needed.

[0034] After the rotary telescopic actuator 12 is started, it drives the stirring rod 14 to enter the fermentation matrix to stir it. The stirring process promotes heat dissipation through mechanical stirring, thereby reducing the temperature of the fermentation matrix.

[0035] When the humidity sensor detects that the humidity in the fermentation box 1 is insufficient, the system will start the humidity supplement device to ensure that the humidity of the fermentation substrate is maintained within an appropriate range. The humidity supplement device belongs to the prior art and will not be described in detail here.

[0036] When the fermentation substrate needs to be turned over and ventilated, the electromagnet in the fixed disk 13 is first started. The function of the electromagnet is to adsorb multiple magnetic oxygen supply balls 2 in the fermentation box 1 to the fixed disk 13. A fixed rod 21 is installed in the magnetic oxygen supply ball 2, and an adsorption ball 22 is installed outside the fixed rod 21. The material of the adsorption ball 22 is activated carbon, which can effectively adsorb oxygen in the air.

[0037] After the rotary telescopic actuator 12 is started, it drives the multiple stirring rods 14 to stir and ventilate the fermentation matrix. During this process, the multiple magnetic oxygen supply balls 2 are affected by the airflow generated by the rotation, so that the airflow overcomes the pressure of the elastic strip 24 in the supplementary release groove 23 on the sealing gasket 25, so that the oxygen in the external air enters the magnetic oxygen supply ball 2 and is adsorbed on the adsorption ball 22 made of activated carbon.

[0038] When the electromagnet is powered off, the magnetic oxygen supply ball 2 separates from the fixed plate 13 and falls into the fermentation matrix. The stirring rod 14 continues to stir to make the magnetic oxygen supply ball 2 evenly distributed in the fermentation matrix. During the fermentation process, when insufficient oxygen causes the temperature to drop, the feedback bar 29 deforms due to the temperature change and squeezes the sealing gasket 25. The squeezing effect of the sealing gasket 25 causes the oxygen adsorbed in the magnetic oxygen supply ball 2 to be released through the supplementary release groove 23, replenishing the oxygen required by the microorganisms and promoting the aerobic fermentation activity of Bacillus licheniformis.

[0039] The fixing rod 21 provides structural support, while the adsorption ball 22 is responsible for adsorbing oxygen. The elastic strips 24 evenly distributed on the supplementary release groove 23 are sealed through the sealing gasket 25. When the airflow pressure is large enough, the elastic strips 24 are overcome, allowing the airflow to enter the adsorption ball 22. The heat-conducting support frame 26 and the heat-conducting block 28 work together to ensure that the temperature change can be transmitted to the feedback strip 29 in time, thereby accurately controlling the release of oxygen.

[0040] Regarding the preparation method of the magnetic oxygen supply ball 2, a corrosion-resistant material with good mechanical strength is selected as the fixing rod 21, such as stainless steel or high-strength plastic. The adsorption ball 22 is made of activated carbon material with high adsorption performance and made into spherical particles of appropriate size to ensure that it can effectively adsorb oxygen in the air. The elastic strip 24 should be made of rubber or elastic plastic material with good elasticity and durability to ensure that the sealing gasket 25 can achieve a good sealing effect. These sealing gaskets are made of materials with good sealing performance and corrosion resistance, such as silicone or fluororubber. The heat-conducting support frame 26 and the heat-conducting block 28 need to be made of metal materials with excellent thermal conductivity, such as aluminum or copper, to ensure that temperature changes can be transmitted in time. The feedback strip 29 is made of an alloy material with a shape memory effect, such as nickel-titanium alloy, to ensure that the sealing gasket can be driven to release when the temperature changes. Prepare materials with good air permeability and waterproof properties to make a breathable and waterproof membrane 27, such as a polymer microporous membrane.

[0041] During the preparation process, the fixing rod 21 is first cut into appropriate lengths and treated for corrosion. Next, the activated carbon material is made into spherical particles of uniform size and subjected to high temperature activation treatment to improve the adsorption performance. Then, the adsorption balls 22 are evenly distributed and surrounded on the outer surface of the fixing rod 21 to ensure a firm connection.

[0042] Subsequently, a plurality of evenly distributed slots are opened on the outer shell of the magnetic oxygen supply ball 2 to form a supplementary release slot 23, and an elastic strip 24 is fixed on the inner wall thereof, one end of the elastic strip is fixedly connected to the sealing gasket 25 to ensure the sealing effect, and then the heat-conducting support frame 26 is fixed to the inner wall of the supplementary release slot 23, and the bottom end of the heat-conducting support frame and the end of the sealing gasket 25 close to each other are fixedly connected to the feedback strip 29, and then, a breathable and waterproof membrane 27 is installed on the inner wall of the supplementary release slot 23 and on the upper side of the heat-conducting support frame 26 to ensure that gas can pass through but moisture cannot enter, and finally, a heat-conducting block 28 is embedded in the outer surrounding of the supplementary release slot 23 to ensure the connection with the heat-conducting support frame.

[0043] The assembled magnetic oxygen supply ball 2 needs to be tested for sealing, adsorption performance, deformation and thermal conductivity. Specific tests include a sealing test on the supplementary release groove 23 to ensure that it can be effectively sealed in a static state; an oxygen adsorption performance test on the adsorption ball 22 to ensure that it can effectively adsorb oxygen in the air during use; a deformation test on the feedback bar 29 to observe whether it can drive the sealing pad 25 to release oxygen when the temperature changes; and a thermal conductivity test on the thermal support frame 26 and the thermal block 28 to ensure that the temperature change can be quickly transmitted to the feedback bar 29. Through these tests, it is ensured that the magnetic oxygen supply ball 2 can effectively adsorb and release oxygen during use to meet the needs of the fermentation process.

[0044] The microbial species in S4 include Bacillus licheniformis, the temperature control range in S5 is 30°C to 60°C, and the humidity control range in S5 is 40% to 70%.
