  Based on FIG. 1, the whole structure of the livestock manure processing system, ie, the pig house manure processing system, is demonstrated.

  The piggery 1 is provided with a raw water tank 2 for storing muddy water (raw water) after washing the manure, and the piggery 1 is supplied with treated water from the treated water tank 3 and is used for washing away the manure. The raw water stored in the raw water tank 2 is introduced into a centrifugal separator 5 which is a solid content separator by an underwater pump 4. In the centrifugal separator 5, the solid content is removed, and the raw water from which the solid content has been removed is sent to the dilution tank 6. Treated water from the treated water tank 3 is pumped to the dilution tank 6 by a pump 7, and the flow rate of the treated water is controlled by a valve 8 so that the raw water in the dilution tank 6 is diluted at a predetermined ratio to be diluted raw water.

  The diluted raw water in the dilution tank 6 is sent to the flocculant addition tank 10 by the water injection pump 9, and the flocculant is added to the diluted raw water in the flocculant addition tank 10. As the flocculant, for example, a natural inorganic material flocculant is used, and sludge described later can be reused. The diluted raw water to which the flocculant is added in the flocculant addition tank 10 is sent to the filtration tank 11, and the flocculant component is filtered from the diluted raw water through the filter 21 in the filter tank 11. The surplus portion of the diluted raw water sent to the filtration tank 11 is sent to the diluted raw water supply port of the flocculant addition tank 10 by the circulation pump 20.

  Aggregated floc 12 (see FIG. 2 described later), which is a solid content filtered and separated in the filtration tank 11, is sent to the separator 13, and the separator 13 removes moisture from the aggregated floc 12 (refer to FIG. 2 described later). The water separated from the flocculation floc 12 (see FIG. 2 described later) is mixed into the diluted raw water liquid from which the flocculated components have been filtered in the filtration tank 11.

  When the size of suspended matter suspended in turbid water is reduced, the sedimentation rate is limited, and therefore separation is difficult only by ordinary precipitation, filtration, and other methods. For this reason, in the present invention, a flocculant is added to make the fine particles into large blocks (floc), thereby increasing the sedimentation speed and enabling efficient separation.

  Although details will be described later, in the filtration tank 11, the agglomeration component is removed by the water pressure of the dilution water introduced from the dilution tank 6 through the water injection pump 9, and the aggregated floc 12 separated by filtration (see FIG. 2 described later). Is introduced into the separator 13. And the separator 13 isolate | separates a water | moisture content from the aggregation floc 12 (refer FIG. 2 mentioned later) with the water pressure of the dilution water introduce | transduced via the water injection pump 9. FIG. The sludge accumulated in the separator 13 is sent to the urine storage 23 by opening and closing the valve 22, and is appropriately processed such as being reused.

  Filtrated water, which is a liquid of diluted raw water in the filtration tank 11 (liquid mixed with water separated from the aggregated floc 12), is sent to the activated carbon treatment tank 15 by the liquid feed pump 14. The activated carbon treatment tank 15 is provided with an introduction path 17 inside a cylindrical main body 16, and activated carbon 18 is filled outside the introduction path 17 in the main body 16. An inlet 17a for filtered water is provided above the introduction path 17, and a lateral 19 for ejecting the filtrate in a foamed state is provided inside the main body 16 at the lower part of the introduction path 17.

  A treated water discharge port 16 a is provided above the main body 16, and the filtered water ejected from the lateral 19 in a foamed state is activated carbon treated with activated carbon 18, and the treated water treated with activated carbon is treated water from the discharge port 16 a of the main body 16. Sent to tank 3. In the activated carbon treatment tank 15, the activated carbon treatment is performed by the water pressure of filtered water introduced by the liquid feeding pump 14.

  Then, the treated water in the treated water tank 3 is sent to the pig house 1 and used for washing away manure and the like. That is, the treatment liquid treated with activated carbon is sent to a muddy water source.

  Therefore, filtration of the flocculated components in the filtration tank 11, separation of moisture from the flocculation floc 12 in the separator 13, activated carbon treatment in the activated carbon treatment tank 15 of the liquid component separated in the filtration tank 11 and moisture separated in the separator 13 Is performed in the process of moving the liquid by the water pressure of the liquid sent by the water injection pump 9 and the liquid feed pump 14, so that the power for each processing becomes unnecessary. For this reason, it becomes a muddy water purification apparatus which can obtain treated water, without requiring the power for purification of muddy water. In addition, since the treatment liquid treated with activated carbon is sent to a muddy water source, a circulating muddy water purification device capable of reusing the treated water is obtained.

  In addition, a second activated carbon treatment tank for secondarily treating the treated water in the treated water tank 3 treated with activated carbon is provided, and the treated water in the treated water tank 3 is treated again with activated carbon and sent to a backwash tank described later. It is also possible to return to the treated water tank 3. The activated carbon treatment tank can be appropriately equipped with three or more tanks as necessary.

  An analysis test result of the raw water stored in the raw water tank 2 and the treated water discharged from the discharge port 16a of the activated carbon treatment tank 15 will be described. The collected raw water and treated water were examined for hydrogen ion concentration (pH), biochemical oxygen demand (BOD), total nitrogen amount (TN), and total phosphorus amount (TP). The hydrogen ion concentration was analyzed by JIS K 0102 12 1 glass electrode method, the biochemical oxygen demand was analyzed by JIS K 0102 21, JIS K 0102 32.3 diaphragm electrode method, and the total nitrogen amount was JIS K 0102 21 K 0102 21, JIS K 0102 45.4 Analyzed by a copper-cadmium column reduction method, and the amount of total phosphorus was analyzed by JIS K 0102 46.3-1 potassium peroxodisulfate decomposition method.

  Hydrogen ion concentration (pH) of raw water is 7.8, biochemical oxygen demand (BOD) is 1310 (mg / L), total nitrogen amount (TN) is 2350 (mg / L), total phosphorus The amount (TP) was 492 (mg / L). In contrast, the hydrogen ion concentration (pH) of the treated water is 8.0, the biochemical oxygen demand (BOD) is 36.8 (mg / L), and the total nitrogen amount (TN) is 38.0. (Mg / L) and the total phosphorus amount (TP) was 1.75 (mg / L). For this reason, it turns out that the water quality is improved and the organic matter (dirt) is remarkably reduced. In addition, it has been confirmed that the suspended matter (SS) mass has been remarkably reduced.

  Moreover, the analysis result of secondary treated water at the time of providing a 2nd activated carbon treatment tank is shown. The hydrogen ion concentration (pH) of the secondary treated water is 8.1, the biochemical oxygen demand (BOD) is 5.2 (mg / L), and the total nitrogen amount (TN) is 17.5 (mg / L), the total phosphorus amount (TP) was 0.993 (mg / L). Therefore, it can be seen that the water quality is further improved and the organic matter (dirt) is further reduced.

  On the other hand, as shown in FIG. 1, in order to supply backwash water for backwashing the filter 21 of the filter tank 11 (washing with water flowing back), activated carbon 18 in the activated carbon treatment tank 15, lateral 19, A backwash tank 25 for supplying backwash water for backwashing the introduction path 17 is provided.

At the same time, the alkali water from the wave water tank 26 is appropriately replenished to the treated water tank 3 by operating the supply valve 27. The alkaline ionized water from the wave water tank 26 is sent to the centrifuge 5 by operating the supply valve 27. Since the alkali ion water from the wave water tank 26 is used on the turbid water side, activated water (alkali ion water) that is negatively ionized and has a small cluster of water can be used for the turbid water purification device.

Alkaline ionized water from the backwash tank 25 is supplied to the filter 21 side (backwashing means described later) of the filtration tank 11 by the first backwash pump 28, and the supply to the filter 21 side is performed at predetermined intervals. The alkaline ionized water from the backwash tank 25 is sent to the inside of the main body 16 above the activated carbon 18 of the activated carbon treatment tank by the second backwash pump 29. The alkaline ionized water sent to the inside of the main body 16 is discharged after backwashing the activated carbon 18, the lateral 19, and the introduction path 17. The discharged alkaline ionized water is sent to the flow path from the treated water tank 3 to the dilution tank 6, and is sent to the dilution tank 6 by driving the pump 7.

  By providing the backwash tank 25 (backwashing means), the filter 21 can be backwashed as part of the purification system, and the purification process can be performed continuously while preventing clogging.

  Next, the structure of the flocculant addition tank 10, the filtration tank 11, and the separator 13 is demonstrated based on FIG. 2 thru | or FIG.

  The filtration tank 11 is demonstrated based on FIG.

  As shown in FIG. 2, the filtration tank 11 is constituted by a first tank part 31 and a second tank part 32, and the first tank part 31 is divided into an upper chamber 31 a and a lower chamber 31 b through a filter 21.

Above the filter 21, backwashing means 34 for supplying backwashing water from above the filter 21 is provided at predetermined intervals, and the alkaline ionized water from the above-described backwashing tank 25 is sent to the backwashing means 34. .

The upper chamber 31a of the first tank section 31 and the lower chamber 32b of the second tank section 32 are connected by a first transfer pipe 35, and the diluted raw water filtered by the first tank section 31 passes through the first transfer pipe 35. It passes through and is sent to the lower chamber 32 b of the second tank portion 32. The dilute raw water overflowing the lower chamber 32b is filtered by the filter 21 and sent to the upper chamber 32a. That is, like the first tank unit 31, the filter 21 filters the diluted raw water to which the flocculant is added from the lower side in the vertical direction toward the upper side. Above the filter 21, backwashing means 34 for supplying backwashing water from above the filter 21 is provided at predetermined intervals, and the alkaline ionized water from the above-described backwashing tank 25 is sent to the backwashing means 34. .

  The circulation of the dilution water in the flocculant addition tank 10, the circulation for the filtration treatment of the dilution water in the filtration tank 11, and the circulation of the water for separating the water in the separator 13 are generated by driving the water injection pump 9. Done by water pressure.

  The flocculant addition tank 10 will be described with reference to FIGS.

  The flocculant addition tank 10 is provided with a spiral spiral channel 46 that extends downward in a cylindrical main body 45. The diluted raw water supply pipe 61 is connected to the spiral flow path 46, and the diluted raw water is supplied from the supply pipe 61 in the tangential direction of the arc of the spiral flow path 46 and supplied along the spiral flow path 46. The main body above the supply pipe 61 is a cylindrical portion 62 that communicates with the spiral flow path 46, and the cylindrical portion 62 has an upper opening, and a lid 63 is attached to the opening. The lid 63 is provided with an addition port 64 through which the flocculant is charged.

The center is fixed. The inside of the main body pipe 48 is in a state where upper and lower flow paths 48 a are formed alternately along the axial direction by a baffle plate member 49. The diluted raw water added with the flocculant flowing through the main body pipe 48 flows through the upper and lower alternate flow paths 48 a formed by the baffle plate members 49, thereby promoting the mixing of the additives. For this reason, the flocculant can be sufficiently mixed with the diluted raw water.

In the process of circulating the filter material 52, the aggregated floc 12 is separated, and the separated aggregated floc 12 is precipitated in the upper chamber 31a and the upper chamber 32a. If the filtration process takes a long time, it is considered that the filter material 52 and the hole 51a of the punching metal 51 are clogged. For this reason, backwashing water 34 is supplied from the punching metal 51 side by the backwashing means 34 every predetermined period, and the aggregated floc 12 attached to the holes 51a and the filter material 52 is caused to flow down to the lower chamber 31b and the lower chamber 32b side.

  The filter 21 has a filter material 52 and a punching metal 51 for filtering the diluted raw water from the lower side to the upper side in the vertical direction. Since the backwash water is supplied from above the filter 21 every period, the clogging of the filter material 52 and the hole 51a of the punching metal 51 can be eliminated without stopping the filtration process. And since the horizontal nozzle pipe 55 is rotated by jetting backwash water from the horizontal nozzles 57a and 57b in opposite directions, the horizontal nozzle pipe 55 is rotated without using mechanical power. Backwashing can be performed evenly over the entire surface of the filter 21.

  The separator 13 will be described with reference to FIGS.

  The separator 13 has a cylindrical tank body 71, and the central part is partitioned into two upper and lower chambers by a filtration part 72. The lower chamber is an introduction chamber 73 on the introduction water side, and the upper chamber is a filtrate water chamber 74 on the filtrate water side. As shown in FIG. 10, protruding guide portions 75 extending in the longitudinal direction of the tank body 71 are formed on the left and right inner walls in the center of the tank body 71. The filtration unit 72 is configured by laminating a large number of rectangular plate members 76 in a long rectangular state, has a plate shape that partitions the inside of the tank body 71 up and down, and has a laminated surface extending vertically. As shown in FIG. 10, a notch 77 that fits into the guide 75 is formed at the end of the flat plate member 76.

  A large number of laminated flat plate members 76 are held in close contact with each other by two bolt shafts 78, and a notch portion 77 at the end is fitted into the guide portion 75, so that a large number of laminated flat plate members are obtained. 76 is held at the center of the tank body 71. By fixing the bolt shaft 78 to the flange portion 79, a large number of stacked flat plate members 76 are fixed at predetermined positions of the tank body 71 between the flange portions 79.

  The introduced water containing the aggregated floc 12 is sent to the introduction chamber 73, and the introduced water overflows into the filtration chamber 74, so that only the moisture of the introduced water flows through the gap between the flat plate members 76 and the moisture moves to the filtered water chamber 74. Thus, moisture is separated from the aggregated floc 12. The separated water is sent to the flocculation tank 41 (see FIG. 2) of the filtration tank 11, and is sent to the activated carbon treatment tank 15 (see FIG. 2) by driving the liquid feed pump.

  The separator 13 can separate only the moisture from the aggregated floc 12 in which fine particles are agglomerated through the gap between the flat plate members 76, thereby simplifying the configuration of the separator 13.

  As described above, the raw water after washing pig manure in the pig house 1 is diluted and then added with a flocculant and filtered, moisture is removed from the flocs floc 12, and further activated carbon treatment in the activated carbon treatment tank 15 is performed. The treated water is sent to the treated water tank 3. At this time, the filtration process, the water separation process, and the activated carbon process are performed in the flow process of the water sent by the water pressure, and thus no power is required for the filtration, the separation of the water, and the activated carbon process. In addition, since the treated water in the treated water tank 3 after treatment is used again as the water for washing away the manure in the pig house 1, a system for purifying manure treatment for circulating livestock is constructed, and the treated water is discharged into the natural environment. There is no need to have a bad influence or to secure a large amount of washing water used for washing, and it becomes an environment-friendly system (processing device) that can effectively use resources.

  Another embodiment of the filtration tank will be described based on FIGS. 11 to 14. The filtration tank 101 of this embodiment is installed instead of the filtration tank 11 shown in FIG.

  As shown in FIG. 11, three filtration tanks 102a, 102b, and 102c are connected in series, and the dilution raw water from the flocculant addition tank 10 is sent to the filtration tank 102a on the most upstream side via the mixing channel 33. It is done. Adjacent filtration tanks 102a, 102b, and 102c are connected to each other by a connecting pipe 104 so that filtered water is sequentially sent to the inlet side. The filtered water from the most downstream filtration tank 102 c is sent to the activated carbon treatment tank 15 by the liquid feed pump 14. The number of filtration tanks 102 may be two, four or more as long as at least one is installed.

  The filtration tanks 102a, 102b, and 102c are provided with a cylindrical filter, which will be described later, and the agglomerated components separated by the cylindrical filter are precipitated in the lower part of the filtration tanks 102a, 102b, and 102c, and the aggregation floc 12 (see FIG. 12). Then, the aggregated floc 12 (see FIG. 12) is sent to the separator 13 via the collecting pipe 103. The moisture from the aggregated floc 12 separated by the separator 13 is sent to the activated carbon treatment tank 15.

  Based on FIG. 12, FIG. 13, the structure of the filtration tank 102 is demonstrated.

  As shown in the figure, the filtration tank 102 is provided with an introduction tank 105, and the introduction tank 105 is supplied with diluted raw water from the mixing flow path 33 (the connecting pipe 104 from the adjacent filtration tank 102) from the flocculant addition tank 10. Is introduced. A storage tank 107 that is partitioned from the introduction tank 105 by a partition wall 106 is provided at the upper corner of the filtration tank 102. A cylindrical filter 108 is detachably provided on the partition wall 106. The cylindrical filter 108 is provided in four rows, that is, eight in two upper and lower stages.

  The diluted raw water introduced into the introduction tank 105 is filtered by the cylindrical filter 108 to separate the agglomerated components, and the liquid component is sent to the storage tank 107. That is, the cylindrical filter 108 is provided with the filter portion positioned in the introduction tank 105. The arrangement state and number of the cylindrical filters 108 are not limited to the illustrated example, and at least one cylindrical filter 108 may be provided.

  The configuration of the cylindrical filter 108 will be described based on FIG.

  As shown in the drawing, the cylindrical filter 108 is formed by laminating a large number of thin plastic ring plates 111 and integrated by, for example, screwing to constitute a filter unit 112, and an end of the filter unit 112. A disc-shaped stop plate 113 is provided at the right end in the figure. The filter part 112 is provided with a cylindrical jig 114, and a screw part 115 is formed on the jig 114. The cylindrical filter 108 is attached to the partition wall 106 by screwing the screw portion 115 to the partition wall 106. As the dilute raw water flows through the gap between the ring plates 111, the agglomerated components are filtered, and the fluid component from which the agglomerated components are separated is stored in the storage tank 107.

  The cylindrical filter 108 can be attached to the partition wall 106 by fitting or the like without depending on the threaded portion 115.

  The diluted raw water sent to the filtration tank 102 is separated into aggregated components by the cylindrical filter 108 and sequentially sent to the filtration tank 102 on the downstream side, and the aggregated floc 12 as the separated aggregated components settles down from the collecting pipe 103. It is sent to the separator 13 to remove moisture as described above. The diluted raw water that has flowed through the cylindrical filter 108 in the filtration tank 102c on the most downstream side is sent to the activated carbon treatment tank 15 by the liquid feed pump 14 (see FIG. 1).

  By applying the filtration tank 101 provided with the filtration tank 102, it is possible to filter the diluted raw water using a cylindrical filter 108 that can be removed with a simple configuration. In addition, since the cylindrical filter 108 is formed by laminating the plastic ring plate 111, it can be easily removed, disassembled and cleaned, and the filter tank 101 having extremely high maintainability can be obtained. In addition, by installing three filtration tanks 102 in series, the flow rate of the diluted raw water can be secured and the filter can be passed multiple times, and the separation of the agglomerated components can be ensured even with the filtration tank 101 having a very simple configuration. Can be done.

  An example of the status of the piggery 1 in the above-described livestock manure processing system will be described with reference to FIGS. 15 and 16.

  As shown in FIG. 15, a plurality of breeding spaces 82 are divided by a fence 81 and arranged in parallel in one direction to construct a row of breeding space groups 83, and each breeding space 82 has a plurality of or one pig. 84 are bred. One pig house 1 is constructed by gathering a plurality of rows of breeding space groups 83, and between each breeding space group 83, a passage 85 is provided for a person who takes care such as feeding food to move.

  A common pit 86 is formed in each breeding space 82 on one side (left side in FIG. 15) of the breeding space group 83, and manure-treated water in each breeding space 82 of the breeding space group 83 in a row is raw water from one pit 86. It is sent to the tank 2 (see FIG. 1). A pipe material 87 extending along each breeding space 82 is provided in the upper part of the other side (right side in FIG. 15) of the breeding space group 83, and the pipe material 87 is treated from the treated water tank 3 (see FIG. 1). Water is supplied.

  A treated water pipe 88 is provided along the breeding space group 83 (left-right direction in FIG. 15), and treated water from the treated water tank 3 is supplied to the treated water pipe 88 by driving a pump 89. One end of a pipe material 87 is connected to the treated water pipe 88 by a rotary joint 90, and treated water supplied to the treated water pipe 88 is sent to the pipe material 87 through the rotary joint 90. The treated water sent to the pipe material 87 is sprayed toward each breeding space 82, and the feces and urine in the breeding space 82 and the body of the pig 84 are washed away and fed into the pit 86.

  On the other hand, the other end of the pipe member 87 is rotatably supported by a support member 91. In other words, the pipe material 87 is pivotally supported around the axis through the rotary joint 90 and the support member 91. Since the breeding space group 83 extends long, the pipe material 87 is also long. For this reason, the pipe member 87 is rotatably supported by a part in the middle (for example, part of the fence 81) (not shown).

  A connecting fitting 92 is fixed to the upper part of the pipe member 87 on the support member 91 side, and the connecting fitting 92 is provided with a long hole 93 that is long in the vertical direction. A driving rod 94 extending in a direction orthogonal to the pipe material 87 is provided on the support member 91 side of the pipe material 87, and the driving rod 94 is reciprocated in the axial direction by the reciprocating driving means 95. The driving rod 94 is provided with a connecting pin 96 corresponding to the pipe material 87, and the connecting pin 96 is relatively rotatably fitted in the long hole 93 of each connecting fitting 92. That is, when the driving rod 94 is reciprocated by the driving of the reciprocating driving means 95, the connecting fitting 92 is swung through the connecting pin 96 and the long hole 93, and the pipe member 87 is simultaneously centered by the swing of the connecting fitting 92. It is rotated around.

  As shown in FIG. 16, a nozzle 98 is provided in correspondence with each breeding space 82 on the breeding space 82 side of the pipe material 87, and treated water is jetted from the nozzle 98 toward the breeding space 82. At this time, the direction of the nozzle 98 can be changed by simultaneously rotating the pipe members 87 around the axis by driving the reciprocating drive means 95, and from the floor surface direction of the breeding space 82 to the body direction of the pig 84. The treated water can be sprayed continuously.

  For this reason, treated water can be spouted toward a wide range of the breeding space 82 without using a large-scale facility, and washing of feces and urine and washing of the body of the pig 84 can be performed unattended. The treated water after washing is collected in the pit 86 and sent to the raw water tank 2.

  Note that the turning mechanism of the pipe member 87 converts the reciprocating motion by the reciprocating drive means 95 into the turning mechanism of the pipe member 87 by the connecting pin 96 and the long hole 93, but it is rotated by using a crank mechanism or a cam mechanism. It is also possible to use a mechanism that converts the force into a rotating mechanism of the pipe member 87.

  The cleaning mechanism described above can be applied to the processing of manure of other livestock such as a cowshed as in the pig house 1. It is also possible to apply the cleaning apparatus of the present invention shown in FIG. 1 to the processing of manure of other livestock such as a cowshed.

  The present invention can be used in the field of turbid water treatment equipment that can obtain treated water without requiring power for purifying turbid water. Moreover, it can utilize in the field | area of the circulation type purification apparatus which can recycle treated water. Furthermore, it can utilize for the coagulant | flocculant addition equipment applicable to the muddy water processing apparatus which can obtain treated water, without requiring the power for purification | cleaning of muddy water.
