Animal manure is rich in organic matter, including nutrients like nitrogen, phosphorus, and potassium, which are beneficial to crop growth. For example, while manure from pig farms and other animal farms can be used for irrigation in tea gardens, untreated manure can have a strong odor. This is especially true when used to irrigate large areas of a tea garden. The strong odor permeates the entire garden, severely impacting the environment and the surrounding area.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] A kind of livestock excrement treatment equipment, Figure 1 、 Figure 2 , including a biogas pool 1, an anaerobic bacteria treatment tank 2 and an aerobic bacteria treatment tank 3. A liquid extraction pipe 4 is provided between the biogas pool 1 and the anaerobic bacteria treatment tank 2, and a liquid extraction pump 5 is provided on the liquid extraction pipe 4; a first liquid discharge pipe 6 is provided between the anaerobic bacteria treatment tank 2 and the aerobic bacteria treatment tank 3, the liquid inlet end height of the first liquid discharge pipe 6 is higher than the liquid outlet end height, and a liquid discharge valve 7 is provided on the first liquid discharge pipe 6.
[0025] In this solution, the animal manure in the farm 37 is transported to the biogas pool 1, which is a relatively closed space. It is subjected to natural anaerobic fermentation treatment for one month. Subsequently, the manure in the biogas pool 1 is pumped to the anaerobic bacteria treatment tank 2 by the liquid pump 5. The anaerobic bacteria treatment tank 2 is added with anaerobic bacteria agents, which can ferment the manure more efficiently, accelerate the degradation of organic matter in the manure, and reduce the generation of manure odor. The treatment time of the anaerobic bacteria treatment tank 2 is about one week; then the corresponding drain valve 7 is opened to discharge the manure into the aerobic bacteria treatment tank 3, which is added with aerobic bacteria agents. The aerobic bacteria agents can promote the degradation and decomposition of organic matter in the manure, which is conducive to further degradation of the intensity of the odor; this solution can enhance the deodorization effect of the manure by performing anaerobic and aerobic fermentation treatments on the manure respectively. Among them, anaerobic bacteria agents can be methane bacteria agents, sulfate-reducing bacteria agents, and lactic acid bacteria agents, and aerobic bacteria agents can be yeast agents, lactic acid bacteria agents, Bacillus subtilis agents, and aerobic microbial composite bacteria agents.
[0026] Based on Example 1, in this example, Figure 1 、 Figure 2 The aerobic bacteria treatment tank 3 is connected to a second drain pipe 8, which is connected to an oxidant treatment tank 9. The liquid inlet of the second drain pipe 8 is higher than the liquid outlet, and a drain valve 7 is also provided on the second drain pipe 8. The oxidant treatment tank 9 contains an oxidant.
[0027] In this solution, opening the drain valve 7 on the second drain pipe 8 allows the manure to be discharged into the oxidant treatment tank 9. This solution utilizes oxidation technology, which uses chemical oxidants to oxidize and decompose organic matter and odorous substances in the manure. Commonly used oxidants include hydrogen peroxide, potassium permanganate, and ozone. Oxidation technology can effectively degrade organic matter and reduce odor.
[0028] Based on Example 2, in this example, referring to Figure 1 、 Figure 2 The oxidant treatment tank 9 is connected to a third drain pipe 10, which is connected to a pure biogas tank 11. The height of the liquid inlet end of the third drain pipe 10 is higher than the height of the liquid outlet end, and a drain valve 7 is also provided on the third drain pipe 10.
[0029] The manure liquid that has undergone anaerobic fermentation, aerobic bacteria treatment and oxidation treatment is discharged into the pure biogas liquid tank 11 for temporary storage, so that the manure liquid can be used for irrigation and planting in tea gardens and other parts in the future.
[0030] Based on Example 3, in this example, referring to Figure 1 、 Figure 2A stepped base 12 is provided beside the biogas pool 1. The anaerobic bacteria treatment tank 2, the aerobic bacteria treatment tank 3, the oxidant treatment tank 9 and the pure biogas tank 11 are placed on different steps of the base 12 in descending order. A downwardly extending sewage main pipe 13 is provided on the base 12, and the lower end of the sewage main pipe 13 is connected to the biogas pool 1; sewage outlets are provided at the bottoms of the anaerobic bacteria treatment tank 2, the aerobic bacteria treatment tank 3, the oxidant treatment tank 9 and the pure biogas tank 11. The sewage outlets of the anaerobic bacteria treatment tank 2, the aerobic bacteria treatment tank 3, the oxidant treatment tank 9 and the pure biogas tank 11 are all lower than the liquid inlet end height of the corresponding drainage pipes. The sewage outlets of the anaerobic bacteria treatment tank 2, the aerobic bacteria treatment tank 3, the oxidant treatment tank 9 and the pure biogas tank 11 are all connected to the sewage main pipe 13 via sewage branch pipes 14, and each sewage branch pipe 14 is provided with a sewage valve 15.
[0031] After a period of sedimentation, a large amount of solid impurities accumulates on the inner bottom walls of the anaerobic bacteria treatment tank 2, aerobic bacteria treatment tank 3, oxidant treatment tank 9, and pure biogas slurry tank 11. Opening the corresponding drain valve 15 allows the impurities at the bottom of the corresponding tank to be discharged into the biogas slurry tank 1 through the drain branch pipe 14 and the main drain pipe 13. The impurities are then deposited and stored at the bottom of the biogas slurry tank 1. In this embodiment, the wastewater is discharged first, depending on the sedimentation status of the lower part of the corresponding tank, and the remaining liquid is then discharged to the next tank.
[0032] Based on Example 4, in this example, referring to Figure 1 、 Figure 2 The pure biogas slurry tank 11 is connected to a fourth drain pipe 16, which is in turn connected to a dilution tank 17. The inlet end of the fourth drain pipe 16 is higher than the outlet end, and a drain valve 7 is also provided on the fourth drain pipe 16. The dilution tank 17 is connected to a tap water pipe 18, which is equipped with a water filling valve 19. Opening the drain valve 7 on the fourth drain pipe 16 allows the pure biogas slurry in the pure biogas slurry tank 11 to be discharged into the dilution tank 17. Opening the water filling valve 19 allows tap water to be added to the dilution tank 17, diluting the biogas slurry and reducing its concentration. This not only reduces its odor, but also allows the ratio of biogas slurry to tap water in the dilution tank 17 to be controlled according to the fertilizer concentration required by the crops, facilitating subsequent irrigation of the crops.
[0033] Based on Example 5, in this example, referring to Figure 1 、 Figure 2The dilution tank 17 is connected to an infusion pipe 20, on which an infusion valve 21 and an infusion pump 22 are provided. A gravel filter 23 and a laminated filter 24 are sequentially provided on the section of the infusion pipe 20 near the pump outlet of the infusion pump 22. The output end of the laminated filter 24 can be connected to the irrigation system 38 of the tea garden. The irrigation system usually includes a drip irrigation pipe and a plurality of drippers arranged on the drip irrigation pipe. The nutrient solution in the dilution tank 17 can be filtered through the gravel filter 23 and the laminated filter 24 to prevent the irrigation system from being blocked.
[0034] Based on Example 1, in this example, Figure 1 、 Figure 2 The swine slurry tank 1 further includes a manure collection tank 25 for collecting manure generated in the pig farm. The manure collection tank 25 is connected to a sewage extraction pipe 26, which is connected to a sewage pump 27. The pump outlet of the sewage pump 27 is connected to a dry-wet separator 28. The discharge end of the dry-wet separator 28 is connected to the biogas slurry tank 1 via a pipeline. The dry-wet separator 28 separates the manure into dry and wet parts, thereby reducing the impurity content of the manure in the biogas slurry tank 1.
[0035] Based on Example 7, in this example, referring to Figure 1 、 Figure 2 A slope 29 is provided inside the manure collection tank 25, and an ultraviolet lamp 30 is provided above the slope 29. The ultraviolet lamp 30 is used to irradiate the slope 29; the manure is poured onto the slope 29 in the manure collection tank 25, and the slope 29 can perform preliminary solid-liquid separation on the manure, and most of the solids will remain on the slope 29, while the liquid in the manure will flow downward through the slope 29 to the bottom of the manure collection tank 25 below; the principle of deodorizing the manure by irradiating the ultraviolet lamp 30 is to use high-energy UV ultraviolet light beams and ozone to carry out a synergistic decomposition and oxidation reaction on the malodorous gas, so that the malodorous gas is degraded into low molecular compounds, water and carbon dioxide, thereby achieving the deodorization effect. The manure collection tank 25 can be deodorized to a certain extent by irradiation with the ultraviolet lamp 30, and the manure can be preliminarily deodorized.
[0036] Based on Example 3, in this example, referring to Figure 1 、 Figure 2The system further includes a compressed air tank 31, which is connected to a gas main pipe 32. The gas main pipe 32 is provided with a gas valve 33. The gas main pipe 32 is connected to a first air pipe 34, a second air pipe 35, and a third air pipe 36. The outlet end of the first air pipe 34 extends to the inner bottom of the aerobic bacteria treatment tank 3, the second air pipe 35 extends to the inner bottom of the oxidant treatment tank 9, and the third air pipe 36 extends to the inner bottom of the pure biogas slurry tank 11. The aerobic bacteria treatment tank 3, the oxidant treatment tank 9, and the pure biogas slurry tank 11 are each provided with an upper opening. Oxygen can be supplied to the inner bottoms of the aerobic bacteria treatment tank 3, the oxidant treatment tank 9, and the pure biogas slurry tank 11, respectively, through the gas main pipe 32, the first air pipe 34, the second air pipe 35, and the third air pipe 36. This accelerates the volatilization of ammonia within the tanks, reducing odor, and increases the oxygen content of the manure within the tanks, thereby promoting the metabolic activity of aerobic microorganisms.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
