Further, the septic tank 74 is connected to a drainage facility through a discharge pipe 75, and the purified waste liquid is discharged to the discharge facility.

  Next, the operation and the like of the vehicle washing system 1 will be described.

  When the vehicle S travels in the entrance direction and enters one end side in the longitudinal direction of the vehicle traveling surface of the floor 4 and the vehicle S is detected by the first detection means 23 and the second detection means 24, the control means 17 It is determined that S has entered.

  When the control means 17 determines that the vehicle S has entered, the opening / closing means of the one end opening 13 and the other end opening 14 of the apparatus main body 11 starts to rise and the lighting means 27 is lit red. . Then, the control means 17 operates the pump 20 when the opening / closing means rises to a predetermined fully open position.

  Note that the control means 17 does not receive the vehicle presence detection signals from the first detection means 23 and the second detection device 24 at the same time, and if it is determined that a person other than the vehicle S, for example, a person has entered, The lighting means 27 is not operated. That is, it does not malfunction due to an approaching object other than the vehicle S.

  Then, when the vehicle S enters the apparatus main body 11, the valve 21 is switched from the closed state to the open state, and the disinfecting liquid is injected toward the vehicle S from the nozzle attached to the nozzle attachment tube 22.

  As a result, while the vehicle S is passing through the vehicle passage space 15, the entire outer surface of the vehicle (the vehicle body and tires of the vehicle S) is cleaned and sterilized with a predetermined amount of the disinfectant from the nozzle.

  Further, by washing the vehicle S in this manner, the pathogenic microorganisms of the soil infectious disease attached to the vehicle body and tires of the vehicle S are removed so as to be washed away.

  When the control means 17 detects the vehicle S with the third detection means 25 and the fourth detection means 26 and determines that the vehicle S has passed through the vehicle passage space 15, the control means 17 stops the pump 20 and opens the valve 21. Then, the opening / closing means of the one end opening 13 and the other end opening 14 is lowered to a predetermined fully closed position.

  In the apparatus main body 11, the waste liquid after washing the vehicle S flows into the concave groove 6, flows through the concave groove 6, and flows into the gutter 32 through the pipe 31.

  The waste liquid that has flowed into the tub 32 gathers in the storage section 37 and is temporarily stored, and is supplied to the separation processing means 38 via the pipe 33a.

  The separation processing means 38 captures solids such as pathogenic microorganisms and dust in the waste liquid supplied from the basket 32 by the filter 44. The filter 44 is rotated by the roller 43, and the solid content captured by the filter 44 moves toward the steam generating means 45 as the filter 44 rotates.

  The steam generating means 45 generates steam, sprays the steam on the moved solid content of the filter 44, and directly heats the pathogenic microorganism and its larvae and eggs, thereby killing the pathogenic microorganism and its larvae and eggs. .

  The solid content containing the pathogenic microorganisms killed by heating by the steam generation means 45 is recovered by the recovery means and stored in the storage unit 49, and then appropriately disposed.

  In addition, the waste liquid from which the pathogenic microorganisms are separated by passing through the filter 44 flows into a high-temperature tank 51 installed below the filter 44.

  In the high-temperature tank 51, the waste liquid that has flowed in is heated by the heater 52, thereby killing pathogenic microorganisms, larvae and eggs remaining in the waste liquid. In addition, the waste liquid that has been killed by the waste liquid heat treatment means 46 is supplied from the high-temperature tank 51 to the energization tank 53 via the pipe 33b.

  In the energizing tank 53, the inflowing waste liquid is energized by passing a current through the pair of electrodes 56, thereby killing pathogenic microorganisms remaining in the waste liquid, and their larvae and eggs by electric shock. Further, the waste liquid that has been killed by the waste liquid energization processing means 47 is supplied from the energization tank 53 to the chemical treatment tank 57 via the pipe 33c.

  In the chemical treatment tank 57, the chemical supply means 58 adds a chemical to the inflowing waste liquid, thereby killing pathogenic microorganisms, larvae and eggs remaining in the waste liquid due to the sterilization action of the chemical.

  Therefore, in the killing processing means 34, the separation processing means 38 separates the pathogenic microorganisms from the waste liquid and kills the separated pathogenic microorganisms, and the waste liquid from which the pathogenic microorganisms have been separated by the separation processing means 38 is contained in the waste liquid. The remaining pathogenic microorganisms are killed by the residual pathogenic microorganism treatment means 39.

  The waste liquid in which the pathogenic microorganisms are killed by the killing treatment means 34 in this way is supplied from the chemical treatment tank 57 to the grease trap 61 via the pipe 35.

  In the grease trap 61, the waste liquid from the chemical treatment tank 57 flows into the first tank part 65, and solids such as garbage and dead bodies of pathogenic microorganisms in the waste liquid are removed in the first tank part 65, and the second The oil in the waste liquid from the first tank 65 is removed in the second tank 66 by flowing into the tank 66. The waste liquid from which oil has been removed in the second tank section 66 is supplied from the third tank section 67 to the aeration tank 71 via the pipe 68.

  In the aeration tank 71, the waste liquid flowing in from the grease trap 61 is aerated by the aeration apparatus 72, whereby the chlorine content in the waste liquid is scattered and the disinfection action derived from the disinfecting liquid in the waste liquid is inactivated. In addition, the waste liquid deactivated by the deactivation processing means 62 is supplied to the septic tank 74 via the pipe 68.

  In the septic tank 74, the waste liquid flowing in from the aeration tank 71 is purified by a purification process so as to satisfy the drainage standard and is rendered harmless. In addition, the waste liquid purified by the purification processing means 63 is discharged through a discharge pipe 75 to a drainage facility such as a sewage main pipe.

  And according to such a vehicle washing system 1, since the waste liquid processing apparatus 3 is equipped with the death process means 34 which has the isolation | separation process means 38 which isolate | separates a pathogenic microorganism from a waste liquid and heats this separated pathogenic microorganism and kills it. The pathogenic microorganisms contained in the waste liquid after washing, for example, that are not killed only by the disinfecting action of the disinfecting liquid used for washing, etc. are separated from the waste liquid by the separation processing means 38, and the separated pathogenic microorganisms are directly treated and appropriately treated. Can be killed.

  The separation processing means 38 has a separation means 41 for separating pathogenic microorganisms from the waste liquid, and a heating means 42 for heating and killing the pathogenic microorganisms separated from the waste liquid by the separation means 41, and directly removing the pathogenic microorganisms separated from the waste liquid. Because it can be heated, pathogenic microorganisms can be effectively killed without using special equipment or special drugs. In particular, when the heating means 42 includes the steam generating means 45, the pathogenic microorganisms can be effectively heated with steam in a short time, so that the pathogenic microorganisms can be appropriately killed.

  Further, the heating means 42 can kill the pathogenic microorganisms more reliably by heating the pathogenic microorganisms at a temperature of 60 ° C. or higher and 120 ° C. or lower for 1 second or longer and 60 seconds or shorter.

  The separation processing means 38 moves the captured pathogenic microorganisms toward the heating means 42 while the filter 44 is rotated by the roller 43 and captures the pathogenic microorganisms from the waste liquid. In addition, pathogenic microorganisms in the waste liquid can be captured and the pathogenic microorganisms can be appropriately killed.

  Since the killing treatment means 34 has the residual pathogenic microorganism treating means 39, even if the pathogenic microorganisms remain in the waste liquid from which the separating pathogenic microorganisms are separated by the separation treating means 38, the remaining pathogenic microorganisms can be killed. Can properly kill pathogenic microorganisms.

  Moreover, since the waste liquid processing apparatus 3 is equipped with the discharge processing means 36 which processes so that the waste liquid which killed the pathogenic microorganism in the death processing means 34 can be discharged to a drainage facility, the waste liquid after the pathogenic microorganism has been killed Can be detoxified, and the load on the water environment due to the discharge of waste liquid can be reduced to prevent natural destruction.

  Here, since the waste liquid of the vehicle washing apparatus 2 contains oil or glass-derived oil adhering to the vehicle body and tires of the vehicle S, the exhaust processing means 36 before purifying by the purification processing means 63. Further, by removing the oil component with the grease trap 61, the load on the purification treatment means 63 can be reduced, and the purification tank 74 can be designed to be small. Therefore, the initial cost and running cost of the purification processing means can be suppressed.

In the above-described embodiment, the waste liquid from the vehicle washing apparatus 2 is processed by the waste liquid treatment apparatus 3. However, the waste liquid treatment apparatus 3 is not limited to such a structure. What is necessary is just a structure which processes the waste liquid containing the pathogenic microorganisms after wash | cleaning the adherend to which the pathogenic microorganisms adhered. For example, the waste liquid treatment apparatus 3 may be configured to treat the waste liquid after manually cleaning the adherend. Further, the waste liquid treatment apparatus 3 may be configured to treat the waste liquid after washing the adherends such as agricultural facilities other than the vehicle S and agricultural tools. Further, waste processing apparatus 3, but it may also be the configuration for processing the waste liquid after washing the object to be adhered object by using the cleaning liquid other than disinfectant.

  The separation processing means 38 is configured to kill the pathogenic microorganisms by the heating means 42, but is not limited to such a configuration, and may be configured to kill the pathogenic microorganisms separated from the waste liquid by, for example, energization or medicine. .

  When the separation processing unit 38 includes the heating unit 42, the configuration is not limited to the configuration in which the pathogenic microorganisms are killed by the steam generation unit 45. For example, a heat transfer plate as an energization heating means that generates heat by energization is arranged in parallel so as to sandwich the filter 44 along the upper side surface of the filter 44, and the heat heating plate in a state where the pathogenic microorganisms captured by the filter 44 are heated You may make it the structure heated by making it contact. Further, a magnetron that generates microwaves may be provided, and the pathogenic microorganisms captured by the filter 44 may be irradiated with microwaves to heat the pathogenic microorganisms. That is, the heating means 42 may be configured to have at least one of energization heat generation means, steam generation means 45, and magnetron.

  In addition, the separation processing unit 38 has a configuration in which the filter 44 of the separation unit 41 can rotate. However, the separation processing unit 38 is not limited to such a configuration, and may have a configuration in which the filter 44 does not rotate.

  Further, the separation processing means 38 is configured to recover the pathogenic microorganisms together with other solid contents after being killed. However, the present invention is not limited to such a configuration, and pathogenic microorganisms separated from the waste liquid together with other solid contents are removed. For example, a configuration may be adopted in which once collected using a scraper or the like, the collected solid content is heated by the heating means 42 or the like to kill pathogenic microorganisms.

  The killing processing unit 34 includes the separation processing unit 38 and the residual pathogenic microorganism processing unit 39. However, the present invention is not limited to such a configuration. For example, as illustrated in FIG. The storage tank 77 may be provided below the separation processing means 38, and the waste liquid may be supplied from the storage tank 77 to the grease trap 61 through the pipe 35.

  Further, in the case where the killing processing means 34 has the residual pathogenic microorganism processing means 39, the residual pathogenic microorganism processing means 39 is limited to the configuration having the waste liquid heating processing means 46, the waste liquid energization processing means 47, and the waste liquid chemical processing means 48. Not. For example, a configuration in which the residual pathogenic microorganism processing means 39 as shown in FIG. 5 has only the waste liquid heating processing means 46, a configuration in which the residual pathogenic microorganism processing means 39 as shown in FIG. 6 has only the waste liquid energization processing means 47, and The residual pathogenic microorganism treatment means 39 as shown in FIG. Further, the residual pathogenic microorganism processing means 39 as shown in FIG. 8 has a waste liquid heating processing means 46 and a waste liquid energization processing means 47, and the residual pathogenic microorganism processing means 39 as shown in FIG. 9 is a waste liquid heating processing means 46 and a waste liquid. A configuration having the chemical treatment means 48 and a configuration in which the residual pathogenic microorganism treatment means 39 as shown in FIG. 10 has the waste liquid energization processing means 47 and the waste liquid chemical treatment means 48 may be adopted. That is, the residual pathogenic microorganism processing means 39 may be configured to include at least one of the waste liquid heating processing means 46, the waste liquid energization processing means 47, and the waste liquid chemical processing means 48.
