Description

Technical Field

[0001] The present invention relates to a treatment device for use in livestock or for treating liquids produced by livestock, a liquid treatment device, a livestock drinking water production device, a livestock drinking water production method, a livestock liquid manure production device, and a livestock liquid manure production method.

Background Art

[0002] Currently, in livestock farming, livestock are being bred, raised, or fattened. In such livestock farming, livestock are raised using groundwater, agricultural water, tap water, etc. As a result, many sites have a certain disease rate and mortality rate, and malodor pollution to surrounding residential areas occurs due to the malodor caused by the decay of manure and urine.

[0003] Therefore, in order to provide a technology capable of preventing the occurrence of diseases, methods and devices for improving livestock drinking water have been developed. For example, in Patent Document 1, as a livestock drinking water production device, a reactor filled with a substance that induces phenolic metabolites is provided, a substance containing a large amount of activated silicic acid is disposed inside or in the vicinity of the reactor, and an air supply unit is provided below the reactor.

[0004] In addition, as an example of improving drinking water by humus, there is also a known technology for improving drinking water by putting pellet-shaped "humus material EZ-901 for producing bioactive water" in a net and hanging it in a tank so that it gradually dissolves into the drinking water.

[0005] Regarding the treatment of livestock excreted urine, its treatment is an extremely important issue for livestock farmers, and it is determined by the "Law Concerning the Optimization of Management and Promotion of Utilization of Livestock Excretions" enacted in 1999. For this reason, it is required to install facilities for managing livestock excretions.

[0006]

Patent Document 1

[0007] However, with conventional methods, the materials used, such as substances that induce phenol metabolites and humus pellets, dissolve and are consumed, so these materials must be continuously purchased. In particular, large quantities of these materials are required when producing drinking water from wastewater or other sources with poor conditions.

[0008] Furthermore, if the raw water contains many impurities such as harmful substances or excess substances, it may be necessary to use different types of filters to remove them, and the process of replacing these filters according to their lifespan may be cumbersome.

[0009] Furthermore, while large-scale farms may be able to install facilities for treating livestock waste, small and medium-sized livestock businesses often lack the space to install new facilities on their premises, making it difficult to predict the future return on investment.

[0010] Although the law has undergone numerous additions and amendments to reach its current state, the difficult situation remains unchanged. One reason for this is likely the costly "treatment methods" proposed by the law.

[0011] Groundwater contamination with excessive nitrite nitrogen, believed to be caused by the untreated disposal of livestock manure, continues to spread nationwide. There are concerns that health problems may be spreading through drinking water and agricultural products, and the generation of foul odors due to inadequate waste disposal is also a major problem in local communities.

[0012] Therefore, the present invention aims to provide a liquid processing apparatus, a livestock drinking water production apparatus, a livestock drinking water production method, a livestock liquid fertilizer production apparatus, and a livestock liquid fertilizer production method that can be used for livestock or that can inexpensively process liquids produced by livestock. [Means for solving the problem]

[0013] According to one aspect of the present invention, a liquid processing apparatus is placed in a liquid and supplied with air from its upper or lower end, comprising: a cylindrical outer container; a plurality of partition plates formed in the shape of a disc and provided inside the outer container; a plurality of cylindrical inner containers provided between the partition plates arranged in the vertical direction; and a plurality of filter materials respectively arranged in the plurality of internal spaces formed in the vertical direction by the plurality of partition plates and the plurality of inner containers, wherein each of the plurality of partition plates has a plurality of water passages with different inner diameters that penetrate through it, the small-diameter and medium-diameter water passages of the plurality of water passages are arranged in the central region of the partition plate, the large-diameter water passages are arranged in a region radially outward from the central region, and at least the lower partition plate forming the lower internal space has a plurality of flow holes different from the water passages, and a plurality of vanes provided above the flow holes, which generate a swirling flow in the water flowing into the flow holes. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide a liquid processing apparatus for use with livestock or for inexpensively processing liquids produced by livestock, a livestock drinking water production apparatus, a livestock drinking water production method, a livestock liquid fertilizer production apparatus, and a livestock liquid fertilizer production method.

Mode for Carrying Out the Invention

[0016] (First Embodiment) Hereinafter, the configuration of the liquid processing apparatus 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 9. Figure 1 is a perspective view showing the configuration of the liquid processing apparatus 1, and Figure 2 is a cross-sectional view showing the configuration of the liquid processing apparatus 1. Figure 3 is a perspective view showing the configuration of the lower processing section 2A of the liquid processing apparatus 1, specifically the first partition plate 21, the inner container 13, and the first filter material 14A. Figure 4 is a perspective view showing the configuration of the middle processing section 2B of the liquid processing apparatus 1, specifically the first partition plate 21, the inner container 13, and the second filter material 14B. Figures 5 and 6 are perspective views showing the configuration of the upper processing section 2C of the liquid processing apparatus 1. Figure 5 shows the configuration of the upper processing section 2C with the top plate 15 in place, and Figure 6 shows the configuration with the top plate 15 omitted, specifically the second partition plate 22, the inner container 13, and the third filter material 14C. Figure 7 is a plan view showing the configuration of the first partition plate 21, and Figure 8 is a cross-sectional view showing the configuration of the first partition plate 21 along line AA in Figure 7. Figure 9 is a plan view showing the configuration of the second partition plate 22.

[0017] The liquid processing device 1 has multiple processing stages 2 for processing liquids within a cylindrical outer container 11, and the liquid is processed by filter media 14 provided in these processing stages 2. The liquids processed by the liquid processing device 1 include raw water such as well water and tap water, and manure and urine excreted from livestock produced in the livestock industry. For example, the liquid processing device 1 can produce drinking water for livestock by processing raw water, and produce liquid fertilizer by processing manure and urine. The liquids processed by the liquid processing device 1 are not limited to these examples, and may also include groundwater, river water, lake water, domestic wastewater, agricultural water, seawater, etc., or even water under unfavorable conditions other than those mentioned above.

[0018] As shown in Figures 1 to 4, the liquid processing apparatus 1 comprises an outer container 11, a plurality of partition plates 12, a plurality of inner containers 13, a plurality of filter media 14, and a top plate 15. The liquid processing apparatus 1 is configured to have a plurality of processing units 2 arranged vertically within the outer container 11 by arranging the plurality of partition plates 12, the plurality of inner containers 13, and the plurality of filter media 14 within the outer container 11. In this embodiment, the liquid processing apparatus 1 will be described as having a configuration having three processing units 2 arranged vertically. In the following description, the three processing units 2 may also be referred to as the lower processing unit 2A, the middle processing unit 2B, and the upper processing unit 2C.

[0019] The outer container 11 is formed in a cylindrical shape. The outer container 11 has a first opening 11a through which piping for supplying air to the bottom can be placed, a plurality of second openings 11b arranged at predetermined intervals in the circumferential direction for inserting hooks for suspending the outer container 11, and a plurality of third openings 11c arranged at predetermined intervals in the circumferential direction. The outer container 11 also has a plurality of support members 11d that are fixed to the plurality of third openings 11c and can support the partition plate 12 by abutting against the lower surface of the partition plate 12 which is located at the bottom. For example, the support members 11d are male threads, and the third openings 11c are screw holes into which the male threaded support members 11d are detachably screwed. The shape and axial length of the outer container 11 can be set as appropriate. The outer container 11 may also have a notch or the like at the lower end to guide the introduction of liquid.

[0020] The partition plate 12 is formed in a disc shape and has multiple through-holes that allow water to pass through. Multiple partition plates 12 are used in at least the lower section 2A. The lower partition plate 12 is formed in such a way that it is possible to convert the upward flow of water into a circumferential flow (swirling flow). The partition plate 12 is formed by press working, and multiple openings are formed during the press working process. Here, the multiple openings are, for example, multiple water passages 21b, 21c, 21d and multiple water flow holes 21e, which will be described later. Since the partition plate 12 is formed by press working, the corners of the openings are formed in a curved shape on the primary side in the punching direction. Furthermore, the partition plate 12 is preferably positioned so that the side with the curved corners of the openings is facing downwards in the vertical direction, in order to guide the flow of liquid and air and reduce resistance.

[0021] For example, three partition plates 12 are provided. Specifically, of the three partition plates 12, the two positioned downwards in the vertical direction are the first partition plates 21 shown in Figures 7 and 8, and the remaining one positioned upwards in the vertical direction, in other words, the one positioned above the uppermost of the two first partition plates 21, is the second partition plate 22 shown in Figure 9.

[0022] As shown in Figures 7 and 8, the first partition plate 21 comprises a plate portion 21a, a plurality of first water passage holes 21b formed in the plate portion 21a, a plurality of second water passage holes 21c formed in the plate portion 21a, a plurality of third water passage holes 21d formed in the plate portion 21a, a plurality of water flow holes 21e formed in the plate portion 21a, a plurality of fins 21f formed integrally with the plate portion 21a and provided above the plurality of water flow holes 21e, and a guide portion 21g for guiding the inner container 13. In addition, for example, the first partition plate 21 has openings 21h formed at equal intervals on the outer edge side of the guide portion 21g of the plate portion 21a. For example, the first partition plate 21 is formed by press working from a plate-shaped base material to create a plate portion 21a, a plurality of first water passage holes 21b, a plurality of second water passage holes 21c, a plurality of third water passage holes 21d, and cut-out pieces that will become blades 21f. By bending these cut-out pieces so that they are inclined relative to the plate portion 21a, a plurality of water flow holes 21e and a plurality of blades 21f are formed. As a result, the plurality of blades 21f are inclined at the same angle in the same circumferential direction, creating a swirling flow in which water flows in one direction in the circumferential direction.

[0023] The plate portion 21a is formed in a circular shape. The outer diameter of the plate portion 21a is formed to be less than or equal to the inner diameter of the outer container 11 so that it can be inserted into the outer container 11. Furthermore, the outer diameter of the plate portion 21a is formed to be larger than the diameter of the inscribed circle passing through the tips of the support members 11d so that it can be supported by the plurality of support members 11d provided on the outer container 11.

[0024] The first water passage hole 21b, the second water passage hole 21c, and the third water passage hole 21d are circular openings formed with different diameters. The inner diameter of the first water passage hole 21b is smaller than the inner diameters of the second water passage hole 21c and the third water passage hole 21d. The inner diameter of the second water passage hole 21c is smaller than the inner diameter of the third water passage hole 21d. That is, when the inner diameter of the first water passage hole 21b is ΦA, the inner diameter of the second water passage hole 21c is ΦB, and the inner diameter of the third water passage hole 21d is ΦD, then ΦA > ΦB > ΦC. For example, the inner diameter ΦA of the first water passage hole 21b is 2.0 mm, the inner diameter ΦB of the second water passage hole 21c is 4.0 mm, and the inner diameter ΦC of the third water passage hole 21d is 6.0 mm.

[0025] For example, the multiple first water passage holes 21b are mostly located in the central region of the plate portion 21a, with some located in a region outside the central region of the plate portion 21a, and closer to the central region than the third water passage hole 21d. Also, for example, the multiple second water passage holes 21c are mostly located in the central region of the plate portion 21a, with some located in a region outside the plate portion 21a, and closer to the outer edge of the plate portion 21a than the third water passage hole 21d. Also, for example, the multiple third water passage holes 21d are located in a region outside the central region of the plate portion 21a. The third water passage holes 21d are located on the outer edge side of the plate portion 21a. Furthermore, these multiple first water passage holes 21b, second water passage holes 21c, and third water passage holes 21d are located on the central side of the plate portion 21a, closer to the guide portion 21g. Therefore, the small-diameter first water passage hole 21b and the medium-diameter second water passage hole 21c are concentrated in the central region of the plate portion 21a, while the medium-diameter second water passage hole 21c and the large-diameter third water passage hole 21d are arranged radially from the central region of the first partition plate 21 outwards.

[0026] For example, these multiple first water passage holes 21b, second water passage holes 21c, and third water passage holes 21d are arranged at regular intervals with a center-to-center distance W1. For example, the center-to-center distance W1 is 10 mm. Also, the outer diameter ΦD of the plate portion 21a is 106 mm.

[0027] The water flow holes 21e are openings formed in a rectangular shape that is elongated in one direction. The water flow holes 21e are arranged so that their longitudinal direction is aligned with the radial direction of the plate portion 21a. Multiple water flow holes 21e are arranged at equal intervals in the circumferential direction. For example, four water flow holes 21e are provided at 90-degree intervals.

[0028] The blade 21f is inclined with respect to the axial direction of the plate portion 21a such that its tip is spaced apart from the plate portion 21a. The end of the blade 21f along the radial direction of the plate portion 21a is integrally continuous with the plate portion 21a and is inclined. Therefore, when liquid rising from the water flow hole 21e along the axial direction comes into contact with the blade 21f, the blade 21f guides the flow of water in a direction perpendicular to the circumferential direction or to both the radial and axial directions of the plate portion 21a. That is, the blade 21f generates a swirling flow in the water flowing into the water flow hole 21e. The blade 21f is formed in a rectangular shape with the length along the radial direction of the plate portion 21a being longer. For example, the blade 21f is formed with a longitudinal width W2 of 15.0 mm and a transverse width W3 of 6.0 mm. Also, the inclination angle θ of the blade 21f with respect to the main surface of the plate portion 21a is, for example, 30 degrees. The number, shape, and angle of the blades 21f can be appropriately set to enable suitable swirling of air and liquid.

[0029] The guide portion 21g is a groove that is recessed to match the shape of the end of the inner container 13. The guide portion 21g guides the position of the inner container 13 when the end of the inner container 13 is inserted into it. The guide portion 21g is an octagonal groove. The opening 21h can be connected to the opening 21h of other adjacent partition plates 12 in the vertical direction with a wire or the like, thereby preventing adjacent partition plates 12 from separating from each other.

[0030] As shown in Figure 9, the second partition plate 22 lacks the water flow holes 21e and vanes 21f of the first partition plate 21, and has a configuration in which multiple first water passage holes 21b, second water passage holes 21c, third water passage holes 21d, guide portion 21g, and opening 21h are formed. Furthermore, the number and arrangement of the first water passage holes 21b, second water passage holes 21c, and third water passage holes 21d of the second partition plate 22 are the same as the number and arrangement of the first water passage holes 21b, second water passage holes 21c, and third water passage holes 21d of the first partition plate 21.

[0031] Multiple inner containers 13 are provided between multiple partition plates 12 arranged vertically, and between the partition plate 12 and the top plate 15 positioned above. The inner containers 13 are formed in a cylindrical shape. For example, the inner containers 13 are formed in a polygonal cylindrical shape. Specifically, the inner containers 13 are formed in an octagonal cylindrical shape. The inner containers 13 are formed, for example, by bending a flat base material into an octagonal cylindrical shape by press working. The diameter of the circumscribed circle of the inner container 13 is formed to be smaller than the diameter of the first partition plate 21 and the diameter of the second partition plate 22. Here, the circumscribed circle of the inner container 13 is an imaginary line passing through the corners on the outer surface of the inner container 13.

[0032] Multiple filter media 14 are arranged in the internal space formed by vertically adjacent partition plates 12 and inner containers 13, and in the internal space formed by vertically adjacent partition plates 12 and top plate 15 and inner containers 13. For example, the height of the internal space is the same for the lower, middle, and upper levels. For example, the height of the internal space is 47 mm.

[0033] For example, as shown in Figures 3, 4, and 6, the multiple filter media 14 are formed with different configurations in the lower processing unit 2A, the middle processing unit 2B, and the upper processing unit 2C. The filter media 14 used in the lower processing unit 2A will be referred to as the first filter media 14A, the filter media 14 used in the middle processing unit 2B as the second filter media 14B, and the filter media 14 used in the upper processing unit 2C as the third filter media 14C, and so on.

[0034] The first filter material 14A comprises eight silica ceramic bodies 31. Specifically, the first filter material 14A includes eight silica ceramic bodies 31 that serve as filter material, a pipe 33 made of ceramic or the like, a ball 34, and a wire 35 that connects these eight silica ceramic bodies 31, pipe 33, and ball 34 in a bead-like manner. For example, the eight silica ceramic bodies 31 are arranged in a bead-like manner by placing four on either side of the pipe 33 and ball 34. That is, the pipe 33, four silica ceramic bodies 31, ball 34, and four silica ceramic bodies 31 are arranged sequentially in the circumferential direction in a bead-like manner, or in other words, in a ring-like arrangement. The first filter material 14A is, for example, placed on the first partition plate 21 below the lower section 2A without being fixed.

[0035] The second filter material 14B has four silica ceramic bodies 31 and eight amphibole ceramic bodies 32. Specifically, the second filter material 14B comprises four silica ceramic bodies 31 that serve as filter material, eight amphibole ceramic bodies 32 that serve as filter material, two pipes 33 made of ceramic or the like, and a wire 35 that connects these four silica ceramic bodies 31, eight amphibole ceramic bodies 32 and two pipes 33 in a double bead-like manner. For example, the eight amphibole ceramic bodies 32 are arranged in a bead-like manner by placing four on each side of the two pipes 33, and the four silica ceramic bodies 31 are arranged in a bead-like manner inside the eight amphibole ceramic bodies 32 by placing two on each side of the two pipes 33. They are arranged in a bead-like manner in four on each side of the pipes 33 and balls 34. That is, the pipe 33, four amphibole ceramic bodies 32, pipe 33, and four amphibole ceramic bodies 32 are arranged sequentially in the circumferential direction in a bead-like (ring-shaped) configuration, and inside these eight amphibole ceramic bodies 32, the pipe 33, two silica ceramic bodies 31, pipe 33, and two silica ceramic bodies 31 are arranged sequentially in the circumferential direction in a bead-like (ring-shaped) configuration. The second filter material 14B is, for example, placed on the first partition plate 21 below the middle section 2B without being fixed.

[0036] The third filter material 14C has four silica ceramic bodies 31 and four amphibole ceramic bodies 32. Specifically, the third filter material 14C comprises four silica ceramic bodies 31, four amphibole ceramic bodies 32, a pipe 33, a ball 34, and a wire 35 that connects these four silica ceramic bodies 31, four amphibole ceramic bodies 32, pipe 33, and ball 34 in a bead-like manner. For example, the four silica ceramic bodies 31 are arranged on one side of the pipe 33 and ball 34, and the four amphibole ceramic bodies 32 are arranged on the other side, thus forming a bead-like arrangement. That is, the pipe 33, four silica ceramic bodies 31, ball 34, and four silica ceramic bodies 31 are arranged sequentially in the circumferential direction, forming a bead-like (annular) arrangement. The third filter material 14C is not fixed, for example, but is suspended by passing the wire 35 through an opening 15a, described later, in the top plate 15 above the upper processing unit 2C.

[0037] For example, the silica ceramic body 31 may consist of 79.8% SiO2, 11.6% Al2O3, 1.2% Fe2O3, 0.2% TiO2, 1.5% CaO, 0.7% MgO, 2.5% Na2O, and 2.5% K2O. The amphibole ceramic body 32 is formed using amphibole, a natural stone.

[0038] As shown in Figure 5, the top plate 15 is formed in a disc shape with multiple openings 15a formed therein. For example, the top plate 15 is formed in a cylindrical shape with its outer edge extending in the axial direction. For example, the top plate 15 is made of perforated metal (perforated plate) and has multiple openings 15a provided at predetermined intervals. That is, the total opening area of ​​the multiple openings 15a of the top plate 15 is larger than the total opening area of ​​the multiple first water passage holes 21b, second water passage holes 21c, third water passage holes 21d and flow holes 21e of the first partition plate 21, and the total opening area of ​​the multiple first water passage holes 21b, second water passage holes 21c and third water passage holes 21d of the second partition plate 22.

[0039] The liquid processing apparatus 1, configured in this way, is placed in the liquid, and when air is supplied from below the lower processing unit 2A via piping, the air rises. A portion of the air then moves into the internal space of the lower processing unit 2A by passing through multiple first water passage holes 21b, second water passage holes 21c, and third water passage holes 21d of the first partition plate 21 of the lower processing unit 2A. The remaining portion of the air also moves into the internal space of the lower processing unit 2A through multiple water passage holes 21e. Below the lower processing unit 2A, the air moves upward. The air that has passed through the multiple water passage holes 21e is then guided to the blades 21f and moves in a swirling direction. Due to this air flow, the liquid inside the lower processing unit 2A becomes a swirling flow.

[0040] Then, the liquid flow generated by the movement of air is processed by the first filter material 14A within the lower processing unit 2A. In addition, the air rises while swirling within the lower processing unit 2A, and a portion of the air moves into the internal space of the middle processing unit 2B by passing through the multiple first water passage holes 21b, second water passage holes 21c and third water passage holes 21d of the first partition plate 21 above the lower processing unit 2A (the first partition plate 21 below the middle processing unit 2B).

[0041] Furthermore, some of the remaining air moves into the internal space of the intermediate processing unit 2B via multiple water flow holes 21e. The air that has passed through the multiple water flow holes 21e is guided to the blades 21f, where it becomes a swirling flow. Due to this air flow, the liquid becomes a swirling flow within the intermediate processing unit 2B and is processed by the second filter material 14B within the intermediate processing unit 2B.

[0042] Furthermore, the air moves into the internal space of the upper section 2C by passing through the multiple first water passage holes 21b, second water passage holes 21c, and third water passage holes 21d of the second partition plate 22 above the middle section 2B (the second partition plate 22 below the upper section 2C). Then, along with the flow of air, the liquid moves from the middle section 2B to the upper section 2C, and the liquid is processed by the third filter material 14C within the upper section 2C, and together with the air, moves to the outside through the multiple openings 15a of the top plate 15.

[0043] With the liquid processing apparatus 1 configured in this way, the air is guided by the vanes 21f of the partition plate 12, allowing the liquid to pass through multiple processing units 2 while swirling and be processed. In particular, the liquid processing apparatus 1 can convert the flow of the liquid into a swirling flow by simply providing the vanes 21f, thereby changing the direction in which the air rises through the liquid to a swirling direction. Therefore, the liquid processing apparatus 1 can process the liquid simply by supplying air below the lower processing unit 2A, thus enabling inexpensive liquid processing.

[0044] As described above, the liquid processing apparatus 1 according to the first embodiment can process liquids at low cost.

[0045] (Second Embodiment) Next, a livestock drinking water production apparatus and a livestock drinking water production method that use such a liquid processing apparatus 1 to produce drinking water for livestock will be described with reference to Figures 1, 2, 10 to 14. Figure 10 is an explanatory diagram that schematically shows the configuration of the livestock drinking water production apparatus 100 according to the second embodiment.

[0046] As shown in Figure 10, the livestock drinking water production apparatus 100 comprises a liquid processing device 1, a drinking water storage tank 101, an air supply device 102, piping 103, and a suspension member 104. The livestock drinking water production apparatus 100 produces drinking water for livestock by filling the drinking water storage tank 101 with raw water, supplying air to the liquid processing device 1 via the air supply device 102, circulating the raw water within the drinking water storage tank 101, and processing the raw water with the liquid processing device 1. In addition to the liquid processing device 1, the livestock drinking water production apparatus 100 may also be configured to suspend a catalyst such as a natural stone to separate, settle, and remove impurities, harmful substances, excess substances, etc., contained in the raw water.

[0047] The drinking water storage tank 101 has a raw water supply port and a treated drinking water discharge port. The drinking water storage tank 101 does not require anything special as long as it is made of the same material as tanks commonly used for drinking water for livestock, however, if the raw water is a special liquid, attention must be paid to its material. In addition, the shape and capacity of the drinking water storage tank 101 can be set as appropriate, but since it is characterized by circulating raw water (treated water), a cylindrical shape is preferable for the drinking water storage tank 101.

[0048] The air supply device 102 supplies air to the liquid treatment device 1 via piping 103. The air supply device 102 is an air compressor. Since the air supply device 102 is used to supply air to the liquid treatment device 1 and treat raw water, the air supply capacity can be determined by the size and shape of the drinking water storage tank 101, the type of raw water to be treated, etc. The air supply device 102 is installed outside the drinking water storage tank 101, adjacent to the drinking water storage tank 101.

[0049] The piping 103 connects the air supply device 102 and the liquid treatment device 1 installed in the drinking water storage tank 101. The piping 103 comprises a first pipe 103a connecting the air supply device 102 to the drinking water storage tank 101, a tube 103b placed in water, an elbow pipe 103c connected to the tube 103b, and a diffuser pipe 103d connected to the elbow pipe 103c. The tube 103b is, for example, flexible and formed to be deformable according to the height position of the liquid treatment device 1. One end of the elbow pipe 103c is positioned upward, and the other end of the elbow pipe 103c is positioned opposite the first opening 11a of the outer container 11 of the liquid treatment device 1. The diffuser pipe 103d is, for example, made of a mesh of 100 μm to 300 μm, is formed in a cylindrical shape, and has its axis positioned horizontally. The diffuser pipe 103d turns the supplied air into fine bubbles and discharges them upward. The diffuser pipe 103d is positioned below the lowest first partition plate 21, at a predetermined interval. For example, the diffuser pipe 103d may be positioned 10 mm away from the first partition plate 21.

[0050] The suspension member 104 suspends the liquid processing device 1 at a predetermined height inside the drinking water storage tank 101. For example, the suspension member 104 comprises a suspension cable 104a, such as a chain, wire, or rope, and a plurality of hooks 104b provided at the end of the suspension cable 104a. The suspension member 104 suspends the liquid processing device 1 by hooking the plurality of hooks 104b onto the second opening 11b of the outer container 11.

[0051] A method for producing drinking water for livestock using the livestock drinking water production apparatus 100 configured in this way is as follows: First, raw water is supplied to the drinking water storage tank 101. Next, the air supply device 102 is driven to supply air to the liquid processing apparatus 1 suspended from the drinking water storage tank 101 (aeration step).

[0052] In the aeration process, when air is supplied to the liquid treatment device 1 suspended from the drinking water storage tank 101, a swirling water flow or a mixed flow of air and water is generated by the multiple water flow holes 21e and multiple blades 21f of the first partition plate 21. This flow causes the water in the drinking water storage tank 101 to circulate around the liquid treatment device 1, allowing the raw water from the entire drinking water storage tank 101 to repeatedly pass through the liquid treatment device 1. By driving the air supply device 102 for a predetermined time, air is supplied for that time, and the raw water repeatedly passes through the liquid treatment device 1. In particular, the water passing through the treatment device 2 as a spiral water flow reacts with the filter material 14 contained in each treatment device 2 (and also with the catalyst, if a catalyst such as a natural stone suspended outside is provided), activating the raw water and making it weakly alkaline. In this way, the raw water is treated by the filter material 14 and produced as water suitable for drinking for livestock.

[0053] Next, after a predetermined time, the water is discharged from the drinking water storage tank 101 to be supplied to the livestock as drinking water. At this time, the air supply device 102 may be stopped after supplying air for a predetermined time.

[0054] With the livestock drinking water production apparatus 100 and livestock drinking water production method configured in this way, livestock drinking water can be processed (produced) at low cost, and the produced livestock drinking water can produce beneficial effects for livestock.

[0055] For example, a livestock farm with 140 sows, 11 breeding pigs, and 1400 growing pigs was struggling with clogged drinking water picks due to fine mud in the drinking water, massive fly infestations, and foul odors from the compost. They converted their underground drinking water tank into a drinking water storage tank 101 and installed a livestock drinking water production device 100. As a result, the pick clogging was resolved immediately, and the fly population drastically decreased within two weeks. Furthermore, feed intake improved, cold-related illnesses decreased, the growth period to market weight shortened, and feed efficiency increased. Also, sow estrus became more pronounced, premature births decreased, and diarrhea during weaning disappeared. Additionally, compost fermentation became smoother, eliminating foul odors, and they successfully converted urine into liquid fertilizer.

[0056] For example, Figures 11 to 13 show examples of odor level values, odor index, and water quality test values ​​at different measurement points (1) to (7) on the farm and in the surrounding area. Figure 11 is the first evaluation result, showing the odor level values ​​detected at each measurement point on the farm. Figure 12 is the second evaluation result, showing the odor index detected at each measurement point on the farm. Figure 13 is the third evaluation result, showing the water quality test values ​​for the drinking water storage tank 101 on the farm.

[0057] The odor level values ​​are those measured using the "Odor Sensor XP-329IIIR" manufactured by Shin-Cosmos Electric. The "level value" has no units and represents the strength of the odor as a numerical value from 0 to 2000. Also, since odors usually exist as complex mixtures of various odor substances, this is an index that quantifies the strength of complex odors rather than single odors. The odor index is an odor index (equivalent value) corresponding to the odor index of the olfactory measurement method measured using the "Odor Sensor XP-329IIIR" manufactured by Shin-Cosmos Electric, and represents the strength of the odor as a numerical value from 00 to 40. For comparison, the standard values ​​under the Water Supply Act are shown in Figure 13. In addition, in the examples in Figures 11 to 13, the livestock drinking water production device 100 was installed on April 19, 2024.

[0058] As is clear from Figures 11 and 12, at measurement points other than measurement point (1) at the entrance to the pasture, the odor level values ​​decreased, and the odor index also decreased after the livestock were given the livestock water produced by the livestock water production device 100. In particular, even during the hot summer months, all values ​​were lower than on April 19th, indicating that the odor decreased when livestock were given the livestock water produced by the livestock water production device 100.

[0059] Furthermore, as shown in Figure 13, the water quality of the drinking water for livestock showed an increase in general bacteria, which is thought to be due to an increase in aerobic cocci. Although E. coli was detected one month after the installation of the livestock drinking water production device 100, it has remained undetectable since July (experiments with E. coli test strips were also conducted from August onwards). In addition, although iron and manganese initially exceeded the standard values, after three months, iron had decreased to 1 / 7 and manganese to 1 / 8, and along with the decrease in iron and manganese, the color values ​​also showed improvement. Furthermore, the amount of nitrite nitrogen, which is harmful to livestock, had decreased to less than half after three months. These results clearly demonstrate that it is possible to improve water quality by installing the livestock drinking water production device 100.

[0060] Furthermore, for example, at the "South Kyushu Livestock and Veterinary Medicine Center," which will open on April 1, 2024, an 8-ton drinking water tank (drinking water storage tank 101) was used as drinking water storage tank 101, and one livestock drinking water production device 100 was installed to conduct a water quality improvement test. As a result, the total sodium and potassium ions in the raw water were high at 29 mg / L, but decreased to 15.5 mg / L in the treated water. In addition, the ORP value of the treated water was low at +178 mv, and it was confirmed that no ammonia odor was generated in the manure and urine of the 40 beef cattle already introduced.

[0061] As is clear from the above, the following can be cited as the local social significance of introducing the livestock drinking water production device 100 and the livestock drinking water production method.

[0062] First, there is the elimination of unpleasant odors. Livestock farming initially operated in locations away from residential areas, but over time, there are cases throughout the country where residential areas have encroached upon the surrounding areas. In such cases, it has become difficult for residents who moved in later to request measures to eliminate unpleasant odors and other issues generated by livestock farming. The obstacle to this is the increased cost and workload for the livestock farmers. However, since the livestock drinking water production device 100 can produce suitable drinking water for livestock at low cost, it is expected that this obstacle can be easily overcome if the livestock farmers and the community as a whole understand and support it provides both direct and indirect benefits.

[0063] Also, for example, in the case of dairy farming, (1) They drink water more, eat more food, and ruminate more frequently. (2) Milk yield and milk quality increase, and somatic cell count decreases. (3) The coat becomes shinier, the odor of feces and urine is reduced, and the emergence of flies can be suppressed. (4) Good compost can be made from manure. (5) Good liquid fertilizer can be made from urine. (6) The use of fungicides, insecticides, disinfectants, etc. will be reduced to almost zero. These benefits will arise.

[0064] For example, Figure 14 shows a graph of the somatic cell count for a specific dairy cow in Okinawa Prefecture on each inspection day, as the fourth evaluation result. In this example, the livestock drinking water production device 100 was installed on April 17th. As is clear from the graph in Figure 14, the somatic cell count decreased one month after the installation of the livestock drinking water production device 100. Thus, providing dairy cows with drinking water produced by the livestock drinking water production device 100 produces desirable effects.

[0065] Also, for example, in the case of pig farming, (1) They drink more water, eat more food, and gain weight faster. (2) The baby will no longer have diarrhea from drinking water during weaning. (3) Feces become harder, the foul odor of urine is reduced, and the emergence of flies can be suppressed. (4) The environment in the stomp-type and slatted-type pigpens will improve, making the pigs less susceptible to colds. (5) The health of the sows becomes normal, and the number of premature births decreases. (6) Good compost can be made from manure. (7) Good liquid fertilizer can be made from urine. (8) The use of drugs other than legally mandated vaccines will be largely discontinued. These benefits will arise.

[0066] Also, for example, in the case of egg-laying chickens, (1) They drink water more, eat more food, and their spawning rate increases. (2) The rate of ovarian rupture decreases. (3) Good compost can be made from manure. (4) The use of drugs other than legally mandated vaccines will be almost completely eliminated. These benefits will arise.

[0067] Furthermore, the aforementioned effects, which occur in parallel with the reduction of unpleasant odors, also bring about indirect benefits such as improved working conditions, increased motivation due to the expected tangible benefits, recognition from local residents, appreciation for providing good compost and liquid fertilizer to nearby farms, and the establishment of a strong work ethic among successors who will be highly regarded for shipping high-quality livestock products.

[0068] Furthermore, various other effects occur. For example, Figure 15 shows the results of water quality tests before and after the installation of a livestock drinking water production system 100 at a poultry farm with approximately 80,000 laying chickens located in the suburbs of Hanoi, Vietnam, as the fifth evaluation result. The water quality tests were performed on drinking water detected at two locations: the drinking water storage tank (receiving tank) 101 and the end tap that discharges drinking water from the drinking water storage tank 101. In Figure 15, KPH means that the relevant component was "not detected," LOD means the "detection limit of the method," and LOQ means the "quantification limit of the method." The reference values ​​are the national technical standards in Vietnam for the sanitation of water used in livestock farming, as defined in "QCVN 01 - 39: 2011 / BNNPTNT."

[0069] As is clear from Figure 15, after installation, BOD (biological oxygen demand) and COD (chemical oxygen demand) were undetectable. In addition, E. coli that was detected before installation was undetectable after installation.

[0070] BOD is an index that measures the amount of oxygen necessary to stabilize and remove organic matter in wastewater through biochemical oxidation involving aerobic microbial systems. BOD is expressed in mg / L or g / m³. 3 It is calculated as follows. COD is the amount of oxygen contained in potassium chromate (K2Cr2O7) and is used to oxidize organic matter in water. The COD index is widely used to indirectly measure the amount of organic compounds in water. Aerobic microorganisms are microorganisms that grow in oxygen-rich environments, oxidizing organic matter and generating energy for growth and development. In addition, the aerobic respiration process of these aerobic microorganisms also contributes to the decomposition of waste in water. Escherichia coli is one of the main causes of intestinal diseases currently known. When E. coli enters the body, after an incubation period of 3 to 4 days, it causes abnormal digestive symptoms such as abdominal pain, diarrhea, fever, fluid loss, and fatigue.

[0071] Furthermore, as an example, Figure 16 shows the results of water quality tests of the drinking water storage tank 101 before the installation of the drinking water production system 100, and four days after the installation and operation of the drinking water production system 100, at a pig farm in Fukushima Prefecture that raises 700 pigs across three farms, as part of the sixth evaluation result. As is clear from Figure 16, E. coli was not detected in the drinking water storage tank 101, and the values ​​for chloride ions, nitrate nitrogen, and hardness decreased.

[0072] These multiple evaluation results clearly show that providing livestock with drinking water produced by the livestock drinking water production device 100 yields favorable results.

[0073] (Third embodiment) Next, a livestock liquid fertilizer production apparatus and a livestock liquid fertilizer production method for producing liquid fertilizer from human waste using the liquid processing apparatus 1 will be described with reference to Figures 1, 2, 17 to 21. Figure 17 is an explanatory diagram showing the configuration of the livestock liquid fertilizer production apparatus 200 according to the third embodiment from above, and Figure 18 is an explanatory diagram showing the configuration of the livestock liquid fertilizer production apparatus 200 from the side. Figures 19 to 21 show a livestock liquid fertilizer production method using the livestock liquid fertilizer production apparatus 200. Note that among the configurations of the livestock liquid fertilizer production apparatus 200 shown in Figure 17, the same reference numerals are used for components that are the same as those of the livestock drinking water production apparatus 100 described above, and their explanations are omitted.

[0074] As shown in Figures 17 and 18, the livestock liquid fertilizer production apparatus 200 comprises a plurality of processing tanks 201, an air supply device 102, a connecting pipe 202 that fluidly connects the air supply device 102 and the processing tanks 201, a connecting pipe 203 that connects the plurality of processing tanks 201, and a discharge pipe 204. The liquid processing apparatus 1 is, for example, placed in at least one of the plurality of processing tanks 201 and installed by the suspension member 104 (not shown in Figures 17 and 18) described above. The livestock liquid fertilizer production apparatus 200 produces liquid fertilizer from human waste by processing it in the plurality of processing tanks 201.

[0075] As multiple treatment tanks 201, for example, three treatment tanks 201 are provided. Hereinafter, they will be described as the first treatment tank 201A, the second treatment tank 201B, and the third treatment tank 201C, starting from the upstream side in the direction of sewage flow.

[0076] The first treatment tank 201A comprises, for example, a tank (first tank) 211, a liquid treatment device 1, and an auxiliary filter material 212. The tank 211 stores human waste supplied from a sanitation tank 250 that stores human waste as shown in Figure 19. The auxiliary filter material 212 is formed from, for example, volcanic rock or granite. Here, the sanitation tank 250 is a tank intended to receive raw urine and then dilute it with water to adjust the CD (electrical conductivity) to 5-8 ms (Siemens). Therefore, the sanitation tank 250 only needs to be able to adjust the raw urine, and may be a large fixed tank or a movable tank. The sanitation tank 250 may be the same tank as the tank 211 used in the treatment tank 201, or it may be different.

[0077] The second treatment tank 201B, for example, is equipped with a tank (second tank) 211, a liquid treatment device 1, and an auxiliary filter material 212, similar to the first treatment tank 201A. For example, the second treatment tank 201B is positioned lower than the first treatment tank 201A. The tanks 211 of both the first treatment tank 201A and the second treatment tank 201B are tanks that perform intermediate treatment when processing liquid fertilizer from human waste.

[0078] The third treatment tank 201C comprises, for example, a tank (third tank) 211 and a liquid treatment device 1. The third treatment tank 201C is a tank for the final treatment of liquid fertilizer.

[0079] For example, each tank 211 uses the same tank. The material and shape of the tank 211 can be set as appropriate, as long as it is resistant to human waste. For example, considering that the tank 211 should be simple and compact, a 60-liter to 100-liter tank is used.

[0080] The connecting piping 202 comprises a main pipe 202a connected to the air supply device 102, branch pipes 202b provided on the main pipe 202a in the same number as the liquid processing device 1 (three in this embodiment), and on-off valves 202c provided on each branch pipe 202b. Furthermore, tubes 103b, elbow pipes 103c, and diffuser pipes 103d are connected to the branch pipes 202b, enabling the supply of air to each liquid processing device 1. The connecting piping 202 supplies air to the liquid processing device 1 performing the aeration process by opening the on-off valves 202c connected to each branch pipe 202b, and stops supplying air to the liquid processing device 1 that does not perform the aeration process by closing the on-off valves 202c.

[0081] The connecting pipes 203 connect adjacent processing tanks 201 among the multiple processing tanks 201. Specifically, two connecting pipes 203 are provided, one connecting pipe 203 connects the first processing tank 201A and the second processing tank 201B, and the other connecting pipe 203 connects the second processing tank 201B and the third processing tank 201C. The connecting pipes 203 are connected to a position where the upstream processing tank 201 is below the full water level, and to a position where the downstream processing tank 201 is above the full water level. The connecting pipes 203 are connected to piping (first piping, second piping) 203a and to on-off valves (first on-off valve, second on-off valve) 203b provided on piping 203a. For example, the connecting pipe 203 switches between supplying and stopping the supply of human waste by opening the on-off valve 203b when supplying human waste from the tank 211 of the upstream treatment tank 201 to the tank 211 of the downstream treatment tank 201, and closing the on-off valve 203b when it is not supplying human waste from the tank 211 of the upstream treatment tank 201 to the tank 211 of the downstream treatment tank 201.

[0082] The discharge pipe 204 is formed to discharge the liquid fertilizer produced in the final treatment tank 201, or in this embodiment, the third treatment tank 201C. The discharge pipe 204 comprises a pipe (third pipe) 204a and an on-off valve (third on-off valve) 204b. For example, the discharge pipe 204 is connected to a position lower (below) than the full water level of the tank 211.

[0083] The livestock liquid fertilizer production apparatus 200 configured in this manner was used. An example of a livestock liquid fertilizer production method will be explained using Figures 19 to 21. In the livestock liquid fertilizer production method, an example will be described in which the livestock liquid fertilizer production apparatus 200 is supplied with manure from a conditioning tank 250. The livestock liquid fertilizer production apparatus 200 may also be configured to include a conditioning tank 250.

[0084] First, the primary urine is stored in the adjustment tank 250, and the primary urine is diluted with water to prepare the urine for treatment. The treated urine is adjusted, for example, to have a CD (electrical conductivity) of 5-8 ms (Siemens).

[0085] Next, the first treatment tank 201A is started up by performing the first treatment and filling it with the treated sewage. For example, sewage is moved from the adjustment tank 250 to the first treatment tank 201A, filling the tank 211, and air is supplied to the liquid treatment device 1 (step ST1). Specifically, the air supply device 102 is driven to supply air to the liquid treatment device 1 in the first treatment tank 201A for a predetermined period (predetermined time), and the sewage is circulated in the tank 211. Here, the predetermined period is, for example, 6 to 10 days, but is set appropriately based on the season, the volume of the tank 211, the properties of the sewage, etc. Here, the criteria for ending the treatment include, for example, when the foul odor disappears.

[0086] Next, the second treatment is performed in the second treatment tank 201B, and the second treatment tank 201B is started up to fill with the treated sewage. For example, the first treatment is performed, and in the first treatment tank 201A, 24 hours after the air supply device 102 is stopped (after a predetermined time has elapsed), one-third of the supernatant sewage from the first treatment tank 201A is transferred to the second treatment tank 201B, air is supplied to the second treatment tank 201B, and the sewage is treated in the liquid treatment device 1 for a predetermined period (for example, 6 to 10 days) (step ST2). Next, the same amount of sewage that has decreased is added to the first treatment tank 201A from the adjustment tank 250, air is supplied to the first treatment tank 201A for a predetermined time, and the sewage is treated in the liquid treatment device 1 (step ST3). Similar to steps ST2 and ST3, the sewage is transferred from the first treatment tank 201A to the second treatment tank 201B two more times until the second treatment tank 201B is full (steps ST4 to ST7).

[0087] Next, the third treatment (final treatment) is performed in the third treatment tank 201C, and the third treatment tank 201C is started up by filling it with the treated sewage. For example, the supply of air to the first treatment tank 201A and the second treatment tank 201B is stopped, and one-third of the sewage in the second treatment tank 201B is transferred to the third treatment tank 201C (step ST8). Next, one-third of the sewage in the first treatment tank 201A is transferred to the second treatment tank 201B (step ST9). Next, sewage is moved from the adjustment tank 250 to the first treatment tank 201A, filling it to capacity, and air is supplied to the first treatment tank 201A, the second treatment tank 201B, and the third treatment tank 201C, and the liquid treatment device 1 is used to treat the sewage for a predetermined period (for example, 6 to 10 days) (step ST10).

[0088] Then, in the same manner as in steps ST8 to ST10, the first treatment tank 201A to the third treatment tank 201C are treated and moved until the third treatment tank 201C is full (steps ST11 to ST16). Then, one-third of the completed bio-liquid fertilizer is taken out of the third treatment tank 201C and stored in storage containers or storage tanks, thereby producing liquid fertilizer (step ST17).

[0089] At step ST17, the first treatment tank 201A and the second treatment tank 201B are full, and the third treatment tank 201C has two-thirds of its liquid remaining. Starting from this state (at step ST17), steps ST13 through ST17 are repeated, enabling continuous treatment of human waste and production of liquid fertilizer.

[0090] According to this livestock liquid fertilizer production apparatus 200 and production method, when an appropriate amount of the liquid fertilizer completed in the third treatment tank 201C is added to a tank that stores raw urine, such as the adjustment tank 250, the humic system becomes more favorable, reducing or eliminating the malodor of the manure (raw urine). Here, the appropriate amount refers to the amount at which the malodor disappears, and this will vary depending on the conditions at each site. In addition, applying weak aeration and creating a slow circulation will accelerate the reduction of the malodor. When the liquid fertilizer completed in the third treatment tank 201C is added during the manure composting process, fermentation will occur well, and compost without malodor will be produced. Furthermore, because malodor-free liquid fertilizer can be produced with a simple configuration, it is easy to use when the liquid fertilizer is put into use.

[0091] This livestock liquid fertilizer production apparatus 200 and method process the human waste in tank 211, extracts a predetermined amount of supernatant liquid, and transfers it to the downstream tank 211. In this way, the liquid components in the first tank 211, second tank 211, and third tank 211 are changed, and the action of different humic bacteria that decompose these components decomposes the organic pollutants contained in the raw urine (human waste). Finally, a liquid (liquid fertilizer) that can be used as bio-liquid fertilizer is obtained in the final treatment tank (third treatment tank 201C). The extracted liquid fertilizer can be stored and used as needed.

[0092] Furthermore, while the livestock liquid fertilizer production method can be operated continuously, it is preferable to prepare the multiple processing tanks 201 (first processing tank 201A, second processing tank 201B) and the final processing tank (third processing tank 201C) to be filled to a state where the processing is progressing in stages. In the livestock liquid fertilizer production method, the processing refers to the operation of a blower that supplies air from the air supply device 102 to the liquid processing device 1. In the liquid processing device 1, the blades 21f of the installed first partition plate 21 generate a water flow or a mixed flow of water and air in a spiral shape, which comes into contact with the filter material 14 installed on the first partition plate 21. It is thought that there are hundreds of types of humic bacteria involved in the decomposition of livestock manure, and it is difficult to quantitatively analyze the decomposition process, so the processing time and the performance of the liquid processing device 1 are set in advance based on experimental values, etc.

[0093] It should be noted that the present invention is not limited to the above-described embodiments. That is, the liquid processing apparatus 1 can be used for purposes other than livestock, and the liquids to be processed can be various. Furthermore, although an example in which air is supplied from the lower end of the liquid processing apparatus 1 has been described, it is not limited to this. For example, as in the other embodiment shown in Figure 22, the liquid processing apparatus 1 may be configured to supply air from the upper end. In the example shown in Figure 22, the air is discharged from the diffuser pipe 103d at the upper end of the liquid processing apparatus 1 and rises, creating an upward flow of water. This water flow creates a water flow below the diffuser pipe 103d that supplies the air, causing water to be drawn up from the first partition plate 21 below the lower processing unit 2A, and creating a water flow in each processing unit 2, similar to the liquid processing apparatus 1 of the first embodiment described above. In addition, since air does not directly enter the processing unit 2, it is possible to suppress imbalances in the air flow, water flow, and the filter media 14 placed inside, as well as damage to the filter media 14, when the pressure of the air discharged from the air supply device 102 is high.

[0094] It should be noted that the present invention is not limited to the embodiments described above, and can be modified in various ways during implementation without departing from its essence. Furthermore, each embodiment may be combined as appropriate, and in that case, the combined effects can be obtained. Moreover, the above embodiments include various inventions, and various inventions can be extracted by selecting combinations from the multiple constituent elements disclosed. For example, if the problem can be solved and effects obtained even if some constituent elements are deleted from all the constituent elements shown in the embodiment, then the configuration with these deleted constituent elements can be extracted as an invention.
