Description

  The present invention relates to a drainage purification system for dental treatment, which contributes to dental hygiene by purifying drainage discharged from a chair unit for treatment by sitting on a patient.

  In conventional dental treatment, water is removed from the vacuum drainage discharged from the chair unit, the drainage is taken out, the air is discharged into the air, and the drainage is passed through a drainage pipe such as an inclined drainage pipe. An effluent discharge device with a has been used. Separately, a circuit for flowing gargle drainage is also provided. Such drainage contains saliva, blood, plaque, etc., and it is unsanitary including various bacteria.

  Since such drainage remains in the water circuit, Japanese Patent Application Laid-Open No. 2009-219723 assumes that the water circuit is provided with a suction circuit that sucks and discharges residual water in the water circuit together with air. Yes. There is another type that pressurizes and discharges residual water in the water circuit.

JP2009-219723 (FIG. 1)

  However, in the conventional drainage discharging apparatus, the drainage is flowed without being purified, and unwillingly provides an unsanitary environment in which saliva, blood, plaque, and the like are mixed and germs grow. Therefore, an object of the present invention is to solve such problems by a simpler method and contribute to dental hygiene. The present invention is intended to contribute to the hygiene of hospitals such as small dental clinics where the total amount of purified wastewater is 50 cubic meters or less per month.

  The above-described problems include a chair unit that is a treatment facility around a patient, a drain separator for removing air from vacuum drain from the chair unit, and a drain from the drain separator. A drainage flow path for flowing gargle drainage from the chair unit, a sterilization water purifier for purifying the drainage by irradiating the drainage path with ultraviolet rays from an ultraviolet germicidal lamp, and the sterilization A drainage purification system for dental treatment, comprising a purification drainage pipe for taking out purified wastewater from a water purifier, and the total amount of purification drainage flowing from the purification drainage pipe is 50 cubic meters or less per month Solve by providing.

  The drainage separator draws air from the vacuum drainage from the chair unit and discharges the drainage. The drainage and the gargle drainage flow into the drainage flow path as in the prior art. In the present invention, a sterilization water purifier is provided in the drainage flow path, and the sterilization water purifier includes an ultraviolet germicidal lamp. The ultraviolet light is irradiated from the ultraviolet germicidal lamp to the drainage of the drainage channel. As a result, the drainage is sterilized and discharged. Unlike the conventional one, the wastewater purified and sterilized as much as possible from the drainage purification system of the present invention is taken out to the purification drainage pipe.

  The ultraviolet germicidal lamp used in the present invention includes a mercury bulb, an ultraviolet LED (Light Emitting Diode), etc., but what kind of ultraviolet germicidal lamp is used is arbitrary. Further, it is more preferable to provide a measuring means for measuring the sterilized and purified waste liquid. It becomes easier to see if the amount of drainage is 50 cubic meters or less per month.

  In the invention of claim 2, the above-mentioned problem is a chair unit as a treatment facility around a patient, a drainage separator for removing air from vacuum drainage from the chair unit, and a drainage separator, A drainage channel for flowing the drainage from the drainage separator and the gargle drainage from the chair unit, and purifying the drainage by injecting ozone from the ozone generator into the drainage channel It is equipped with an ozone sterilization water purifier that collects residual ozone and a purification drain pipe for taking out purified waste water from the ozone sterilization water purifier, and the total amount of purified waste water flowing from this purification drain pipe is 50 cubic meters or less per month The problem is solved by providing a drainage purification system for dental treatment.

  An ozone generator is provided, ozone from this ozone generator is injected into the drainage, and the drainage is sterilized and purified by oxygen in the generation period. The remaining ozone in the purified wastewater is safe because it is recovered from the drainage channel.

  In the invention of claim 3, the above-mentioned problem is a chair unit as a treatment facility around a patient, a drainage separator for removing air from vacuum drainage from the chair unit, A drainage flow path for flowing the drainage from the drainage separator and the gargle drainage from the chair unit, and generating the drainage by irradiating the drainage path with ultrasonic waves from an ultrasonic generator An ultrasonic sterilization water purifier for purifying the waste liquid by ultrasonic cavitation, and a purification drain pipe for taking out the purified waste water from the ultrasonic sterilization water purifier. The problem is solved by providing a drainage purification system for dental treatment, wherein the total amount is 50 cubic meters or less per month.

  An ultrasonic generator is provided, and the wastewater is irradiated with ultrasonic waves generated from the ultrasonic generator. Then, a vacuum bubble is generated in the drainage by the irradiated ultrasonic wave, but this bursts directly and generates a shock wave. And the sterilization purification is done by this shock wave. As described later, scraps that are scraps that have been cut from teeth, and dirt that adheres to metal pieces that are scraps from which padding has been cut, are lifted from the tooth scraps and metal pieces by shock waves caused by cavitation and peeled off by acceleration. It will be taken away by straight flow.

  Next, a chemical sterilization water purification unit for sterilizing the drainage from the drainage flow path with a chemical is provided at the front stage or the rear stage of the sterilization water purification apparatus, or inside the sterilization water purification apparatus. I can do it. Especially in hospitals such as small dental clinics where the total amount of purified wastewater is 50 cubic meters or less per month, the conventional drainage drainage device is a mixture of saliva, blood, plaque, etc., and unsanitary bacteria are propagated. Was drained without purification. In this sterilization water purifier of the present invention, the drainage flow path is irradiated with ultraviolet rays from an ultraviolet sterilization lamp to purify the drainage liquid, and further equipped with a chemical sterilization water purification unit for sterilization with chemicals. It is said to be highly effective. It has been found that some drugs can increase their medicinal effects even after the sterilizing water purifier.

  The medicine in the medicine sterilization water purification unit can be easily maintained, for example, by replacing it with a cartridge. Further, for example, odor can be adsorbed by using activated carbon in combination. Further, it is possible to continue the sterilization effect even in a place where the sterilization effect of ultraviolet rays does not reach.

  The chemical sterilization water purification unit is used in particular in the front stage or inside of the sterilization water purifier, and chlorinated isocyanuric acid can be used as a chemical. The sterilizing water purifier is provided with an ultraviolet germicidal lamp, and when the ultraviolet light is irradiated from the ultraviolet germicidal lamp to the drainage of the drainage flow path, the ultraviolet radiation has an action of promoting the decomposition of chlorine. Under such circumstances, the granular or granular drug of chlorinated isocyanuric acid can cope with an increase in the chlorine concentration even with an increase in the amount of sewage.

  The chemical sterilization water purification unit can use calcium hypochlorite as a chemical. Although it is so-called bleaching powder and calcite, it is used inside the chemical sterilization water purification part, and has the advantage that the sterilization effect lasts long because it dissolves gradually in water.

  Next, a metal recovery unit for separating and recovering metal from the drainage from the drainage flow path is provided at the front stage or the rear stage of the sterilization water purifier or inside the sterilization water purifier. It can be. For the gargle drainage and vacuum drainage of the chair unit, the pieces of fungus in the place where the teeth are cut and the metal piece in the place where the filling is cut are gold, silver, platinum, titanium and palladium. It contains expensive metals. In the past, these were handled as waste and discarded together with the drainage. However, there is no way to recover and reuse these metals with economic value that may be called urban mines.

  Therefore, a metal recovery unit is incorporated in the drainage purification system of the present invention. It should be noted that the metals recovered in the metal recovery section are purified by the drainage purification system of the present invention, and the subsequent handling is more hygienic.

  The metal recovery unit can rotate the waste liquid containing the metal in the separation tank and separate the metal from the waste liquid by the centrifugal force generated at this time. The drainage of the drainage channel is introduced into, for example, a cylindrical separation tank so that the drainage vortex is generated and then discharged. If the drainage is introduced along the wall surface of the separation tank, the vortex of the drainage is generated in the separation tank by the momentum of the drainage. Then, relatively heavy tooth pieces and metal pieces gather at the center of the separation tank, and other lighter things swirl outside the center of the vortex instead of being swept away from the separation tank. . As a result, the tooth pieces and metal pieces collected in the center can be collected.

  Further, the metal recovery unit can introduce a drainage liquid containing metal into the recovery container, precipitate the metal in the recovery container by the weight of the metal, and discharge the waste liquid separated from the metal from the recovery container. . If there is a recovery container in the drainage flow path, relatively heavy tooth pieces and metal pieces in the drainage that flowed in here will settle into the recovery container, It is discharged from the collection container. As a result, it is possible to collect the tooth pieces and metal pieces that have settled in the collection container.

  A plurality of such recovery containers can be used. That is, it is assumed that a plurality of recovery containers are arranged side by side along the drainage flow path. According to the structure of the collection container arranged stepwise in the drainage flow path, larger pieces and heavy tooth pieces and metal pieces settle in the first collection container, but did not settle here. Teeth fragments and metal pieces flow over the first collection container wall and fall into the next collection container, and tooth pieces and metal pieces that have not settled at this stage will flow into the next collection container. . Accordingly, the tooth pieces and metal pieces are arranged in a plurality of collection containers arranged in a stepwise manner, and these collections are more convenient.

  In the drainage purification system of the present invention, the sterilization water purifier may be provided with an ultraviolet germicidal lamp facing the drainage flow path. There are various designs for irradiating the waste liquid with the ultraviolet light from the ultraviolet germicidal lamp, but the design of providing the ultraviolet germicidal lamp so as to face the drainage flow path is simpler. For example, it is not so difficult to provide a sterilizing water purifier around the inclined drainage pipe under the floor of the treatment room. In addition, the sterilizing water purifier may be configured by providing a plurality of ultraviolet germicidal lamps in the drainage channel along the drainage channel. Since the space between the ultraviolet germicidal lamps of the sterilizing water purifier becomes a drainage flow path, the drainage flowing here is sterilized and purified with higher efficiency by the ultraviolet rays.

  Moreover, the purification | cleaning waste_water | drain tank shall be equipped with the purification | cleaning drainage tank for accumulating the purification | cleaning wastewater. This purified waste water tank is more sanitary than the prior art because it collects purified waste water after it has been sterilized with ultraviolet rays.

  Further, a pump for pumping water may be interposed in the drainage channel. As mentioned above, it is possible to install a sterilizing water purifier around the inclined drainage pipe under the floor of the treatment room. However, in some cases, only the inclined drainage pipe can be passed under the floor of the treatment room. There is also an architectural structure. Therefore, for example, if the design is such that a sterilizing water purifier is provided in the wall surface, a design using a pump for pumping the drainage to the sterilizing water purifier may be used.

  Moreover, the water purifying tank for filtration can be further provided in the front | former stage or the back | latter stage of the said sterilization water purifier. As a filter member of the water purification tank, various stones such as charcoal and tourmaline grains, plant stems and bark such as firewood, synthetic resin fiber for water purification, etc. are raised. The drainage can be purified by passing the drainage through such a water purification tank. That is, a synergistic effect between the sterilizing water purifier and the water purification tank in the drainage purification system of the present invention can be obtained.

  According to the drainage purification system for dental treatment of the present invention, by irradiating ultraviolet light from the ultraviolet germicidal lamp of the sterilization water purifier to the drainage flow path of the chair unit, or by injecting ozone from an ozone generator, Or, by irradiating ultrasonic waves from an ultrasonic generator, the effluent can be sterilized and purified, contributing to the dental hygiene of small clinics where the total amount of purified wastewater is 50 cubic meters or less per month. Even though it is simple, there are immeasurable industrial benefits. In addition, the thing provided with the chemical | medical-agent sterilization water purification part for sterilizing with a chemical | medical agent can raise a higher sterilization effect. In addition, in the case of having a metal recovery unit for separating and recovering metals, it is possible to recover and purify the metals having economic value while purifying them.

  Hereinafter, ten examples of the present invention will be described with reference to FIGS. 1 to 10, but the present invention is not limited to these examples.

  Although FIG. 1 relates to the drainage purification device 1 of the present embodiment, the chair unit and the drainage separator are not shown (see FIG. 2 of Embodiment 2). A drainage pipe 13 connected from the chair unit or the drainage separator is connected to the sterilizing water purifier 10. The sterilizing water purifier 10 has a cylindrical shape, and an inside thereof is a drainage flow path 11. A plurality of ultraviolet sterilization lamps 12 are spaced from each other in the drainage flow path 11, and the drainage flow path 11. It is stretched along. That is, since the space between the ultraviolet sterilizing lamps 12 of the sterilizing water purifier 10 is the drainage flow path 11, the drainage flowing therethrough is sterilized and purified with high efficiency by the ultraviolet rays. The sterilizing water purifier 10 may be provided with an ultraviolet reflector 18 outside the drainage flow path 11 as indicated by a chain line.

  The purified waste water thus sterilized and purified is stored in the purified waste water tank 15 via the purified drain pipe 14. Reference numeral 16 denotes a tank drain pipe of the purification drain tank 15, and a flow meter 17 is attached thereto. It is confirmed that the monthly cumulative amount of waste liquid measured and accumulated by the flow meter 17 is 50 cubic meters or less. The flow meter 17 may be an integrated flow meter.

  A vacuum drainage pipe 21 and a gargle drainage pipe 22 are taken out from the chair unit 20 of the drainage purification apparatus 2 of the present embodiment, and the vacuum drainage pipe 21 is connected to a drainage separator 24. The drainage port of the drainage separator 24 is connected to the inclined drainage pipe 23 through the drainage valve 25 together with the gargle drainage pipe 22. Since the inclined drainage pipe 23 is installed in an inclined state, these drainage flows naturally downstream.

  A transparent pipe 26 as a drainage flow path 200 is provided downstream of the inclined drainage pipe 23, and the transparent pipe 26 is covered with a sterilizing water purifier 27. The sterilizing water purifier 27 includes a plurality of ultraviolet sterilizing lamps 28 provided around the transparent pipe 26 and a reflector 29 provided in each of them. The reflector 29 plays a role of reflecting the ultraviolet rays emitted from the ultraviolet germicidal lamp 28 toward the transparent pipe 26. A purification drain pipe 201 is connected downstream of the transparent pipe 26.

  According to the present embodiment, the sterilizing water purifier 27 is a simple one in which the ultraviolet sterilizing lamp 28 is provided around the transparent pipe 26, but the effect is that the effluent can be sterilized and purified by this. Play. That is, it is more hygienic than the prior art.

  FIG. 3 relates to the drainage purification apparatus 3 of the present embodiment, and the chair unit and drainage separator are not shown, but the drainage pipe 33 connected from the chair unit and drainage separator is a sterilizing water purifier 30. The purification drainage pipe 34 of the sterilization water purifier 30 is taken out from the bottom of the sterilization water purification apparatus 30 and connected to the purification drainage tank 35. Reference numeral 36 indicates a tank drain pipe of the purification drain tank 35.

  In the inside of the sterilizing water purifier 30, since the slopes 37 are combined in four stages with the inclination directions being alternately changed, the drainage flows down in a zigzag manner through the drainage flow path 32 indicated by the arrow. . At this time, ultraviolet rays are irradiated from the ultraviolet irradiation wall surface 31 in the back of FIG. Accordingly, the drainage is efficiently sterilized and purified by being repeatedly irradiated with ultraviolet rays through the long drainage channel 32. The ultraviolet irradiation wall surface 31 is a glass surface, and an ultraviolet germicidal lamp (not shown) is disposed behind this surface.

  From the chair unit 40 of the drainage purification device 4 of this embodiment, a vacuum drainage pipe 41 and a gargle drainage pipe 42 are taken out, and the vacuum drainage pipe 41 is connected to a drainage separator 44. The discharge port of the drain separator 44 is connected to the drain pipe 43 along with the gargle drain pipe 42 via the drain valve 45. The drainage pipe 43 is installed horizontally in this embodiment.

  A transparent pipe 46 is downstream of the drainage pipe 43, and the transparent pipe 46 is covered with a sterilizing water purifier 47. The sterilizing water purifier 47 includes a plurality of ultraviolet sterilizing lamps 48 provided around the transparent pipe 46 and a reflector 49 provided in each of them. The sterilizing water purifier 47 is installed at a position higher than the horizontally disposed drainage pipe 43. Accordingly, the pumping pump 401 is interposed between the drainage pipe 43 and the transparent pipe 46 so that the drainage can be raised to the transparent pipe 46 that is the drainage flow path 400.

  Thus, the drainage liquid passing through the flow path of the transparent pipe 46 of the sterilization water purifier 47 is sterilized and purified by being irradiated with ultraviolet rays from the surrounding ultraviolet sterilization lamp 48, but is further relayed 401 connected from the transparent pipe 46. The purified wastewater thus obtained is filtered in the water purification tank 403, and the purified wastewater thus obtained is discharged from the purification drainage pipe 404, while the cumulative flow meter 405 easily confirms that the monthly cumulative amount of waste liquid is 50 cubic meters or less. . In the present embodiment, the water purification tank 403 is filled with a total of four layers of filtering substances of two types of activated carbon and two types of hollow fiber membranes, which can be replaced as a cartridge.

  FIG. 5 relates to the drainage purification device 5 of the present embodiment, but the chair unit and the drainage separator are not shown (see FIG. 2 of Embodiment 2). A drainage pipe 53 connected from the chair unit or the drainage separator is connected to the sterilizing water purifier 50. The sterilizing water purifier 50 has a cylindrical shape, and the inside thereof is a drainage flow path 51, and a plurality of ultraviolet sterilization lamps 52 are spaced from each other in the drainage flow path 51. It is stretched along. That is, since the space between the ultraviolet sterilization lamps 52 of the sterilizing water purifier 50 is the drainage flow path 51, the drainage flowing therethrough is sterilized and purified with high efficiency by ultraviolet rays. The sterilizing water purifier 50 may be provided with an ultraviolet reflector 58 outside the drainage flow path 51 as indicated by a chain line.

  The drainage pipe 53 connected to the chair unit or drainage separator connected to the sterilization water purifier 50 is provided with a drug sterilization purification unit 55 in the middle thereof. A cartridge type medicine 56 is stored in a replaceable manner. The drug 56 is granular calcium hypochlorite in this example. Accordingly, the drainage flowing down the drainage pipe 53 is sterilized and purified by the chemical sterilization and purification unit 55.

  The purified waste water sterilized and purified through the chemical sterilization and purification unit 55 and the sterilized water purifier 50 in this way is stored in the purified waste water tank through the purified drain pipe 54. A flow meter (not shown) is attached to the tank drain pipe of this purification drainage tank, and it is confirmed that the monthly cumulative amount of waste liquid accumulated here is 50 cubic meters or less.

  FIG. 6 relates to the drainage purification apparatus 6 of this embodiment, and the chair unit and drainage separator are not shown, but the drainage pipe 63 connected from the chair unit and drainage separator is a sterilizing water purifier 60. The purification drainage pipe 64 of the sterilization water purifier 60 is taken out from the bottom of the sterilization water purification apparatus 60 and connected to a purification drainage tank (not shown).

  In the inside of the sterilizing water purifier 60, since the slopes 65 are combined in four stages with the inclination directions being alternately changed, the drainage flows down in a zigzag manner through the drainage flow path 62 indicated by the arrow. . At this time, ultraviolet rays are irradiated from the ultraviolet irradiation wall surface 61 in the back of FIG. Accordingly, the waste liquid is efficiently sterilized and purified by being repeatedly irradiated with ultraviolet rays through the long drainage flow path 62. The ultraviolet irradiation wall surface 61 is a glass surface, and an ultraviolet germicidal lamp (not shown) is disposed behind this surface.

  Further, the feature of this embodiment is stored on the slope 65 so that the medicine 66 is not caused to flow by the drained liquid flowing down. Agent 66 is particulate chlorinated isocyanuric acid in this example. Therefore, the drainage flowing down the slope 65 is sterilized and purified by the chemical 66 of the slope 65 which is also the chemical sterilization and purification unit. The reason for using chlorinated isocyanuric acid for the drug 66 is that when ultraviolet rays are irradiated from the ultraviolet irradiation wall surface 61 as in this embodiment, the ultraviolet rays strongly act in the direction of promoting the decomposition of chlorine. The presence of isocyanuric acid delays the decomposition of chlorine because isocyanuric acid is subjected to the action of ultraviolet rays prior to chlorine. Therefore, the chlorinated isocyanuric acid of the drug 66 can cope with a large amount of sewage by increasing the chlorine concentration.

  Finally, other embodiments will be described. It is arbitrary what kind of thing is used for the sterilization water purifier provided with the ultraviolet germicidal lamp. Also, a drainage channel for flowing the drainage from the drainage separator and a drainage channel for flowing the gargle drainage from the chair unit are provided separately, and a sterilizing water purifier is applied to each. Configurations are also within the scope of the present invention. In addition, gargle drainage refers to drainage that has not been vacuumed, and in this sense, it can be read as gargle drainage. That is, the present invention includes a chair unit that is a treatment facility around a patient, a drain separator for removing air from the vacuum drain from the chair unit, and a drain from the drain separator. A drainage channel for flowing liquid and non-vacuum drainage from the chair unit, a sterilizing water purifier for purifying the drainage by irradiating the drainage channel with ultraviolet rays from an ultraviolet germicidal lamp, and A drainage purification system for dental treatment, comprising a purification drain pipe for taking out purified waste water from a sterilizing water purifier.

  FIG. 7 relates to the drainage purification device 67 of this embodiment, and the chair unit and drainage separator are not shown, but the drainage pipe 63 connected from the chair unit and drainage separator is a sterilization water purifier 68. The purification drainage pipe 64 of the sterilization water purifier 68 is taken out from the bottom of the sterilization water purifier 68 and connected to a purification drainage tank (not shown).

  Since the inside of this sterilizing water purifier 68 is combined in four stages by alternately changing the direction of the part that becomes the drainage flow path 62 where the stepped partition plate 69 is connected to the lower stage, the drainage flow indicated by the arrow line The drainage flows down the path 62 in a zigzag manner. At this time, ultraviolet rays are irradiated from the ultraviolet irradiation wall surface 61 in the back of FIG. Accordingly, the drainage is efficiently sterilized and purified by being repeatedly irradiated with ultraviolet rays through the long drainage flow path 62. The ultraviolet irradiation wall surface 61 is a glass surface, and an ultraviolet germicidal lamp (not shown) is disposed behind this surface.

  The feature of this embodiment is that an ozonizer 600 for generating ozone O3 is provided on the central side surface of the sterilizing water purifier 68, and ozone for recovering ozone O3 on the upper top surface of the sterilizing water purifier 68. The recovery device 602 is provided. With respect to the drainage flowing down the long drainage channel 62, the ozone channel 601 is formed so as to trace back the drainage channel 62. Therefore, the waste liquid flowing in from the drainage pipe 63 is not only exposed to the ultraviolet irradiation from the ultraviolet irradiation wall surface 61, but also strongly receives the oxidizing action by the oxygen O in the generation stage of the ozone O3 that goes up the ozone flow path 601. It will be sterilized and purified.

  If ozone O3 is contained in the purified drainage discharged from the purification drainage pipe 64 and the remaining ozone O3 is not allowed to leak under the floor of the treatment room, the remaining ozone O3 is sterilized. It is desirable to be collected inside the water purifier 68. For that purpose, the ozone recovery device 602 having the suction fan F is provided, and the above-mentioned concerns can be solved and the user can feel safe. It is also possible to provide a sterilizing water purifier with chemicals at the end of the purification drain pipe 64.

  FIG. 8 relates to the drainage purification apparatus 202 of the present embodiment, and most of the configuration is similar to that of the second embodiment described above, but differs in that a sterilizing water purifier 203 having an ultrasonic oscillator 204 is provided. . That is, the vacuum drainage pipe 21 and the gargle drainage pipe 22 are taken out from the chair unit 20 of the drainage purification apparatus 202, and the vacuum drainage pipe 21 is connected to the drainage separator 24, and the drainage liquid is discharged. The outlet of the separator 24 is connected to the inclined drainage pipe 23 through the drainage valve 25 together with the gargle drainage pipe 22.

  A sterilizing water purifier 203 is provided downstream of the inclined drainage pipe 23, and a drainage flow path 200 is provided from the inclined drainage pipe 23 to the sterilizing water purifier 203. An ultrasonic oscillator 204 is installed on the top surface of the sterilizing water purifier 203 so as to face the inside of the sterilizing water purifying device 203. A purification drain pipe 205 is connected to the discharge tool of the sterilization water purifier 203.

  According to the present embodiment, the waste water flowing into the sterilizing water purifier 203 from the drainage flow path 200 is sterilized and purified by hitting the ultrasonic wave S emitted from the ultrasonic oscillator 204. That is, a vacuum bubble is generated in the drainage liquid by the irradiated ultrasonic wave, which is directly ruptured to generate a shock wave. The shock wave is sterilized and purified, and is discharged from the purification drain pipe 205. In addition, you may provide the sterilization water purifier by a chemical | medical agent next to this purification | cleaning drain pipe 205. FIG.

  FIG. 9 relates to the drainage purification device 7 of this embodiment, and is characterized in that a metal recovery unit such as gold and silver is provided. The sterilizing water purifier 70 of the drainage purification device 7 has a cylindrical shape, and a drainage pipe 72 is connected to the upper side wall part, and a purification drainage pipe 73 is connected to the lower side wall part. Although not shown, when the sterilizing water purifier 70 is viewed in plan, the drainage pipe 72 is attached to one side with respect to the circumferential wall surface of the sterilizing water purifier 70, and the purification drainage pipe 73 is biased to the other side. It is attached. With this structure, the waste water that has flowed into the cylindrical sterilizing water purifier 70 from the drainage pipe 72 descends along the circumferential wall surface and is conveniently discharged from the purification drainage pipe 73. That is, the drainage flows down while creating the drainage flow path 71 in a vortex form in the sterilizing water purifier 70.

  On the other hand, a metal outlet 74 is disposed at the bottom center of the sterilizing water purifier 70. As described above, the drainage has been described as creating a vortex of the drainage flow path 71 in the sterilizing water purifier 70. However, the lighter substances contained in the drainage flow due to this vortex, and the vortex is generated. Heavier materials such as gold and silver gather at the center of the vortex. Therefore, the tooth pieces and metal pieces (symbol M) collected at the center can be recovered from the metal outlet 74.

  Now, the circumferential wall surface of the sterilizing water purifier 70 is made of a transparent wall 75 made of glass, and the sterilizing water purifier 76 is attached to the outside thereof. The sterilizing water purifier 76 is composed of a plurality of ultraviolet sterilizing lamps 77 provided around the transparent wall 75 and a reflector 78 provided in each of them. The reflector 78 plays a role of reflecting the ultraviolet rays emitted from the ultraviolet germicidal lamp 77 toward the transparent wall 75.

  Therefore, as described above, the drainage flowing down while making the drainage flow path 71 in a vortex form in the sterilizing water purifier 70 is sterilized by being exposed to ultraviolet rays irradiated from the sterilizing water purifier 76 in the process. It will be purified. That is, both the metal recovered from the metal outlet 74 and the drained liquid discharged from the purification drain pipe 73 are more sanitary than the prior art. In addition, the design which provides the sterilization water purifier by a chemical | medical agent in the side of this purification | cleaning drain pipe 73 is also possible.

  FIG. 10 relates to the drainage purification apparatus 8 of this embodiment, and is characterized in that a metal recovery unit such as gold and silver is provided. In the drainage purification device 8, three separation tanks 80, a separation tank 81, and a separation tank 82 are arranged in series along the drainage flow path 83 in a stepped manner. A drain pipe 84 connected to a chair unit or drain separator (not shown) is connected to the top of the first separation tank 80, and a drain pipe 87 of the last separation tank 82 is a lower side surface of the separation tank 82. And is connected to a purification drainage tank (not shown) through a chemical sterilization water purification unit 89 and a purification drainage pipe 88. Note that a cartridge-type medicine 800 is attached to the medicine sterilization water purification unit 89. This is responsible for the drainage purification in this embodiment.

  The separation tank 80, the separation tank 81, and the separation tank 82 as the collection containers arranged side by side in a stepped manner are formed so that the separation wall 85 between the separation tank 80 and the separation tank 81 is formed low. The separation wall 86 between the tank 81 and the separation tank 82 is similarly formed low.

  With this configuration, the following operation is observed in the drainage purification device 8 of the present embodiment. That is, the drainage liquid flows from the drainage pipe 84 to the first separation tank 80, passes through the separation wall 85 and the separation wall 86 and reaches the drainage pipe 87 from the last separation tank 82 to the drainage pipe 87. Tooth pieces and metal pieces that are likely to settle are deposited in the first stage separation tank 80, but tooth pieces and metal pieces that have not settled here pass over the separation wall 85 of the first stage separation tank 80, and the middle stage separation tank. Tooth pieces and metal pieces that have flowed down to 81 and did not settle even at this stage pass over the separation wall 86 of the middle separation tank 81 and further flow down to the last separation tank 82. Therefore, the tooth pieces and metal pieces are shaped as separated by the three-stage separation tank 80, the separation tank 81, and the separation tank 82 that are arranged side by side in a stepped manner, and the collection of these is more convenient. It becomes.

  The drainage liquid from which the tooth pieces and the metal pieces (M1, M2, M3) are separated in this way is discharged from the drainage pipe 87 and passes through the drug sterilization water purification unit 89 by the drug 800 of the drug sterilization water purification unit 89.
