Description

  The present invention relates to a cleaning processing apparatus that performs cleaning processing for the purpose of sterilization and disinfection using ultraviolet rays for gases and liquids, and particularly relates to a cleaning processing apparatus suitable for plant factories and refrigerators.

  In recent years, practical application of plant factories has been studied. The plant cultivation facility of the plant factory is equipped with artificial lighting equipment at the top and a cultivation stand at the bottom, and the whole room is maintained under conditions suitable for plant growth to grow plants. Moreover, the nutrient solution required for growing the plant is supplied to the plant on the cultivation stand. The nutrient solution is sterilized and purified by a purification device and used again. The purification device sterilizes the nutrient solution by irradiating it with ultraviolet light.

  Moreover, in an ice making device incorporated in a refrigerator, ultraviolet rays are irradiated from an ultraviolet lamp to an ice making plate to sterilize germs and the like attached to the ice making plate.

  The sterilization using ultraviolet rays is intended only for liquids such as plant factory nutrient solution and refrigerator ice making water. However, it is preferable to purify not only liquid but also air in plant factories and refrigerators.

  For example, Patent Document 1 is known as a liquid and a gas that are simultaneously cleaned by irradiation with ultraviolet rays. In the processing apparatus of Patent Document 1, a cylindrical apparatus body, a jacket that transmits ultraviolet light having a diameter smaller than that of the apparatus body, and an ultraviolet lamp are mounted inside the apparatus body. The apparatus main body, the jacket, and the ultraviolet lamp are installed coaxially, and a space through which water flows is formed between the apparatus main body and the jacket. A space through which air flows is formed between the ultraviolet lamp and the jacket. As a result, the air purification and water treatment are combined with a single device.

Japanese Patent Laid-Open No. 3-65288

  In the case of the processing apparatus of Patent Document 1, it is difficult to increase the flow rate of air to be processed. In order to increase the air flow rate, it is necessary to enlarge the jacket. However, if the jacket is enlarged, the distance between the water and the ultraviolet lamp is increased and the sterilizing effect of the water is reduced.

  The present invention has been made in view of the above-mentioned problems, and the intended process is that when a cleaning process is performed by simultaneously irradiating ultraviolet rays with a gas at the same time as the liquid, the distance between the ultraviolet lamp and the liquid is increased. Even so, an object of the present invention is to provide a treatment apparatus in which the effect of water treatment is difficult to reduce.

In order to achieve the above object, the present invention provides a cylindrical jacket (1), at least one linear first ultraviolet lamp (2) inside the jacket (1), and a fluorine-based fluorine-permeable material. A cylindrical tube (3) made of a material, a blower (5) for blowing gas into the jacket (1), and an infusion device (7) for sending liquid into the tube,
The inner surface of the jacket (1) is an ultraviolet reflecting surface (8),
The ultraviolet lamp (2) is disposed along the cylindrical tube central axis direction of the jacket,
The tube (3) is wound inside the jacket (1), a plurality of times spirally around the ultraviolet lamp (2) with a gas layer (4) therebetween,
The gas sent by the blower (5) flows through the gas layer (4),
The ultraviolet light irradiated by the ultraviolet lamp irradiates the liquid (6) sent by the infusion device (7) through the gas layer (4), the gas layer (4) and the tube (3), and A gas and liquid simultaneous cleaning treatment apparatus characterized by irradiating a liquid (6) in a gas layer (4) and a tube (3) after a part of the light is reflected by the ultraviolet reflecting surface (8) provide.

  According to invention of Claim 1, both gas and a liquid can be processed by ultraviolet irradiation simultaneously. Moreover, since the liquid flows through the spirally wound ultraviolet transmission tube, the flow path length can be increased. As a result, the gas layer can be enlarged, and even if the amount of energy that reaches the liquid is small because the distance between the UV lamp and the tube is small, the irradiation processing time with small energy can be extended, and the liquid and gas processing can be performed. Capability can be improved. Therefore, the entire processing apparatus can be reduced in size.

Furthermore, the gas and liquid simultaneous cleaning apparatus has a second ultraviolet lamp inside the jacket, and the tube winds around the first ultraviolet lamp and around the second ultraviolet lamp. It is characterized by not.
Thereby, an air layer can be enlarged and the ultraviolet irradiation light quantity with respect to the liquid which passes the inside of a tube can be increased.

Furthermore, the jacket is made of a metal material, and a photocatalytic layer is formed on the inner surface of the jacket.
Thereby, especially the decomposition capability of ethylene gas improves.

According to another aspect of the present invention, a cylindrical jacket (61), at least one linear first ultraviolet lamp (2) inside the jacket (61), and a fluorine-based material capable of transmitting ultraviolet rays A hollow tube (3), a blower (5) for blowing gas into the jacket (61), and an infusion device (7) for sending liquid into the tube,
The jacket (61) is formed of an ultraviolet transmissive material,
The ultraviolet lamp (2) is disposed along the cylindrical tube central axis direction of the jacket (61),
The tube (3) is outside the jacket (61), and the outer periphery of the jacket (61) is spirally wound a plurality of times,
The gas sent by the blower (5) flows through the gas layer (4) between the inner wall of the jacket (61) and the ultraviolet lamp (2),
The ultraviolet light irradiated by the ultraviolet lamp (2) passes through the gas layer (4) and the liquid (6) sent by the infusion device (7) through the jacket (61) and the tube (3). A simultaneous gas and liquid cleaning treatment device (60), characterized by irradiation, is provided.

  According to the present invention, both gas and liquid can be treated simultaneously by ultraviolet irradiation. Moreover, since the liquid flows through the spirally wound ultraviolet transmission tube, the flow path length can be increased. Even if the gas layer is enlarged and the distance between the UV lamp and the tube is large and the amount of energy that reaches the liquid is small, the irradiation processing time with small energy can be extended, and the processing capacity of liquid and gas Can be improved. In addition, since the tube is provided on the outer periphery of the jacket, it is possible to relatively easily replace the ultraviolet lamp.

  According to the present invention, water can be sterilized and air can be simultaneously purified with a single gas and liquid simultaneous cleaning apparatus. In the liquid cleaning treatment, the liquid can be irradiated with ultraviolet rays for a long distance by winding the tube a plurality of times spirally in the length direction of the ultraviolet lamp. Thereby, even if it is a case where the distance between an ultraviolet lamp and a liquid is provided, a long time ultraviolet-ray can be irradiated to a liquid. At the same time, the air flow can be increased by increasing the distance.

  Hereinafter, a simultaneous gas and liquid cleaning apparatus according to an embodiment of the present invention will be described with reference to FIGS.

<First Embodiment>
FIG. 1 is a schematic perspective view showing an example of a configuration of a gas and liquid simultaneous cleaning apparatus 10 according to a first embodiment of the present invention. A gas and liquid simultaneous cleaning processing apparatus (hereinafter abbreviated as “processing apparatus”) 10 of this embodiment includes a cylindrical jacket 1, an ultraviolet lamp 2 inside the jacket, and an inner surface of the jacket near the inner surface. It consists of a hollow tube 3 that wraps around the ultraviolet lamp 3, a blower device 5 provided on one side of a pair of open ends of a cylindrical jacket, and an infusion device 8 that sends liquid into the tube.

  The jacket 1 has a cylindrical shape and is made of a metal material. When the size of the inner diameter of the jacket is compared with the length of the jacket inner diameter in the central axis direction, the cylindrical shape has a long length in the central axis direction, that is, a vertically long cylindrical shape. By lengthening the length in the central axis direction, it is possible to increase the length of the gas processing path for the air cleaning process described later. Further, the inner surface of the jacket 1, that is, the inner peripheral surface is a reflecting surface 8 made of a mirror surface with improved smoothness. The reflecting surface 8 is an ultraviolet reflecting surface that reflects the ultraviolet rays emitted from the ultraviolet lamp 2.

  The metal used for the jacket 1 is preferably aluminum (Al) or an alloy containing aluminum as a main component. This is because aluminum has a high ultraviolet reflectance and a high thermal conductivity. When the thermal conductivity is high, the heat generated by the lighting of the ultraviolet lamp can be efficiently radiated to the outside. Moreover, although the base material of the jacket 1 was used as it is for the ultraviolet reflecting surface 8, it may be provided with an ultraviolet reflecting film separately on the inner surface. Further, instead of the metal material, a resin material in which a single-layer or multi-layer ultraviolet reflecting film that does not transmit ultraviolet rays is provided on the inner surface facing the ultraviolet lamp can be used.

  The ultraviolet lamp 2 has an elongated shape, and electrodes are provided at both ends in the length direction. Among the ultraviolet rays, those having a lamp characteristic of light emission having main wavelengths of 254 nm and 185 nm are used. For example, a mercury discharge lamp in which argon gas, neon gas, and mercury are enclosed can be used. As an ultraviolet lamp that does not use mercury, a discharge lamp in which xenon gas and xenon iodide (XeI) are enclosed, a discharge lamp in which xenon gas is enclosed, and a phosphor layer that emits ultraviolet rays with its excitation light are provided. Specifically, for example, when a mercury discharge lamp having a lamp length of 150 mm and a lamp diameter of 4.7 mm is lit at a lamp current of 10 mA, light having main wavelengths of 254 nm and 185 nm can be obtained. The ultraviolet lamp 2 is disposed along the central axis of the jacket. As a result, the ultraviolet lamp 2 is positioned at the center of the air layer 4, and the air layer 4 can be irradiated with ultraviolet rays without unevenness.

  The tube 3 is disposed inside the jacket 1 and wound around the ultraviolet lamp 2 in a spiral manner with a gas layer 4 therebetween. The hollow interior of the tube 3 serves as a water channel 6a through which the water 6 to be treated passes. By arranging the tube 3 so that the water channel 6a becomes a spiral passage that goes around the ultraviolet lamp 2, the water channel 6a is fixed as compared to the case where the water channel 6a is a cylindrical space as in Patent Document 1. It can flow through the water channel, and its length can be increased. By making the length of the water channel 6a longer and making it a spiral channel, the treated water 6 is irradiated with ultraviolet light over a long distance from the water channel entrance to the outlet. It will be. Therefore, ultraviolet energy can be utilized without waste. In particular, the tube 3 is irradiated with ultraviolet light over a long distance, and the ultraviolet lamp 2 is orthogonal to the flow of the liquid 6 to be treated, so that the water 6 to be treated is completely mixed. The mixed water 6 to be treated advances relative to the ultraviolet lamp 2 while changing its relative positional relationship. In other words, the water to be treated 6 facing the ultraviolet lamp 2 is mixed while traveling through the water channel 6a, and the water receiving the ultraviolet rays is not always located on the same surface, and irradiates the entire treated water uniformly. Thereby, ultraviolet light is irradiated to the to-be-processed water 6 whole, and effects, such as disinfection and disinfection, go up.

  The ultraviolet light emitted from the ultraviolet lamp 2 first irradiates the air layer 4. And the ultraviolet light which passed the air layer 4 irradiates the to-be-processed water 6 which flows through the water channel 6a through the tube 3. FIG. Further, a part of the ultraviolet light that has passed through the air layer 4 is reflected by the ultraviolet reflecting surface 8 and then irradiates the air layer 4 and the water 6 to be treated in the tube 3. By providing the ultraviolet reflecting surface 8, it is possible to irradiate the treated water 6 in the tube with ultraviolet light from the back side of the tube 3, that is, the side not facing the ultraviolet lamp 2, so that the ultraviolet energy can be utilized more efficiently. it can.

  The tube 3 is formed of a material that transmits ultraviolet light. In particular, a fluorine-based resin material is preferable. By using a resin material, it can be easily spirally wound. Specifically, PFA (tetrafluoroethylene / perfluoroalkyl vinyl ether copolymer), FEP (tetrafluoroethylene / hexafluoropropylene copolymer (4.6 fluoride)) PTFE (polytetrafluoroethylene (tetrafluoroethylene (tetrafluoride)) )) Etc. can be used. In particular, PFA and FEP are suitable because they have high transparency that transmits about 90% of ultraviolet light having a wavelength of 254 nm and have stable properties with respect to various liquids as water to be treated.

In addition, the present inventors performed prior measurement in order to confirm the ultraviolet transmittance. The preliminary measurement was performed by inserting the ultraviolet lamp 2 having a lamp diameter of 4.7 mm into the tube 3 having an outer diameter of Φ8 mm and an inner diameter of Φ6 mm, and arranging a light receiving sensor at a position 5 mm away from the outer periphery of the tube. The amount of ultraviolet rays with and without the case was measured. Three types of tube materials were used: PFA, FEP, and PTFE. As a result, the PFA is 0.90 times, the FEP is 0.89 times, and the PTFE is 0. 0 with respect to the ultraviolet light (mW / cm ² ) of a bare ultraviolet lamp without a tube for 254 nm ultraviolet light. It was 52 times. For ultraviolet light of 185 nm, PFA was 0.18 times, FEP was 0.02 times, and PTFE was 0.01 times the ultraviolet light amount (μW / cm ² ) of the bare ultraviolet lamp. .

  At one end 1a of the cylindrical opening of the jacket 1, a blower 5 and an infusion device 7 are disposed in the vicinity of the cylindrical opening. The blower 5 blows air to the air layer 4 inside the jacket 1 and discharges it from the other end 1 b of the jacket 1. The blower 5 can control the amount of blown air. Since the ultraviolet lamp 2 is disposed inside the jacket 1, the air layer 4 is cleaned by ultraviolet irradiation. The infusion device 7 is, for example, an in-line pump, and feeds the water 6 to be treated into the tube 3 and discharges it from the tube outlet on the other end 1 b side of the jacket 1. By controlling the infusion device 7, the amount of infusion can be controlled.

By the way, the light emitted from the ultraviolet lamp is attenuated when it is separated from the lamp as the light source. The illuminance (dose rate) from the point light source decreases with the square of the distance from the light source, and the attenuated dose rate is expressed by I = S / 4π ² . Here, I is the illuminance (dose rate) (μW / cm ² ), S is the energy of the light source (μW), and x is the distance (cm). As can be understood from this equation, in order to reduce the attenuation, it is preferable to provide the air layer 4 and the tube 3 as close to the ultraviolet lamp 1 as possible.

  However, if the small diameter spiral shape is used to provide the tube 3 as close as possible so that the water 6 to be treated passes near the ultraviolet lamp 1, the volume of the air layer 4 inside the spiral is reduced. On the contrary, if the volume of the air layer 4 is increased, the distance between the water to be treated 6 and the ultraviolet lamp 1 is increased, and the illuminance is attenuated. Therefore, in the present invention, by providing the tube 3 in a spiral shape, the moving distance of the water to be treated 6 is lengthened and the time for receiving ultraviolet rays is lengthened. Moreover, the flow of the to-be-processed water 6 in the tube 3 is made to generate turbulent flow. Furthermore, the axis of the ultraviolet lamp 1 and the flow of the treated water 6 are such that the central axis of the spiral of the tube 3 wound in a spiral shape with respect to the axis of the ultraviolet lamp 1 is directed in the same direction as the axis of the ultraviolet lamp. Are substantially orthogonal to each other to increase the total amount of ultraviolet rays received by the water 6 to be treated. Thereby, both gas and liquid can be efficiently processed simultaneously by ultraviolet irradiation.

  Also, an ozone blocking unit 9 is provided at the end 1b (air outlet) of the jacket 1 by mounting an activated carbon filter or an ozone decomposition catalyst for capturing ozone. The ozone blocking part 9 is preferably spread over the entire cross section of the jacket opening end 1b with activated carbon. When ozone is generated by turning on the ultraviolet lamp 2, the ozone can be completely blocked. When a minute amount of ozone is required, the minute amount of ozone is allowed to pass through by placing activated carbon in a lattice pattern. A small amount of ozone that has passed through can be effectively used for sterilization of plant surface bacteria.

<Second Embodiment>
FIG. 2 is a schematic perspective view showing an example of the configuration of the processing apparatus 20 according to the second embodiment of the present invention. The processing apparatus 20 of the present embodiment includes a cylindrical jacket 1, an ultraviolet lamp 2 inside the jacket, a hollow tube 3 around the ultraviolet lamp 3 in the vicinity of the inner surface of the jacket, and a pair of cylindrical jackets. The point provided with the blowing device 5 provided on one side of the opening end and the infusion device 8 for sending the liquid into the tube is the same as the processing device 10 of the first embodiment, so the same reference numerals are used. A detailed description is omitted here.

  In the second embodiment, an umbrella-shaped windbreak 21 surrounding the lamp end 2a of the ultraviolet lamp 2 is further arranged on the end 1a (air inlet side) side of the jacket 1. When air is blown directly onto the ultraviolet lamp 2 using the excitation of mercury, the ultraviolet lamp is cooled, the vapor pressure of mercury is reduced, and the ultraviolet irradiation efficiency is deteriorated. Therefore, a wind shield 21 having a size smaller than the inner diameter of the jacket 1 is provided on the windward flow of the air layer 4, that is, between the end 2 a of the ultraviolet lamp 2 and the blower 5. The wind shield 21 may be plate-shaped, lattice-shaped, or cylindrical, and various shapes can be used as long as the amount of air hitting the ultraviolet lamp is reduced. The windshield 21 is preferably provided only in the vicinity of the lamp end 2a, and preferably does not cover the light emitting part of the ultraviolet lamp. This is because when the light emitting portion is covered, the windshield 21 absorbs the irradiated ultraviolet rays, and the amount of ultraviolet rays reaching the air layer 4 and the water to be treated 6 is decreased, which is not preferable.

<Third Embodiment>
3A and 3B are explanatory views showing an example of the configuration of the processing apparatus 30 according to the third embodiment of the present invention. FIG. 3A is a schematic perspective view, and FIG. 3B is a cross-sectional view. The basic configuration of the processing apparatus 30 of the present embodiment is the same as that of the processing apparatus 10 of the first embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted here.

  In the processing apparatus 10 of the first embodiment, the example in which the number of the ultraviolet lamps 2 is one has been described. However, in the processing apparatus 30 of the third embodiment, the first ultraviolet lamp is provided in the jacket 1. In addition to 2, a second ultraviolet lamp 32 around which the tube 3 is not wound is provided. The second ultraviolet lamp 32 is placed in the jacket 1 and is substantially parallel to the first ultraviolet lamp 2 between the jacket 1 and the tube 3 spirally wound around the first ultraviolet lamp 2. It arrange | positions as follows. When the second ultraviolet lamp 32 is lit, ultraviolet rays can be applied from both the front and back sides to the tube 3 positioned between the first ultraviolet lamp 2 and the second ultraviolet lamp 32. Also. The amount of ultraviolet rays in the air layer can be increased, and the amount of air purification can be increased.

<Fourth embodiment>
4A and 4B are explanatory views showing an example of the configuration of the processing apparatus 40 according to the fourth embodiment of the present invention. FIG. 4A is a schematic perspective view, and FIG. 4B is a cross-sectional view. The basic configuration of the processing apparatus 40 of this embodiment is the same as that of the processing apparatus 10 of the first embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted here.

  In the processing apparatus 10 of the first embodiment, an example in which the number of the ultraviolet lamps 2 is one has been described. However, in the processing apparatus 40 of the fourth embodiment, four ultraviolet lamps are provided in the jacket 1. 2 are arranged at equal intervals, and the tube 3 is arranged so as to be spirally wound around all of the four ultraviolet lamps 2. In addition, the distance between the four ultraviolet lamps 2 and the tube 3 was made close. Thereby, when the jacket 1 having the same size as that of the first embodiment is used, the amount of generated ultraviolet rays can be increased, and the intensity of ultraviolet rays applied to the water to be treated 6 flowing in the tube can be increased.

<Fifth embodiment>
FIG. 5 is a schematic perspective view showing an example of the configuration of the processing apparatus 50 according to the fifth embodiment of the present invention. The basic configuration of the processing apparatus 30 of the present embodiment is the same as that of the processing apparatus 20 of the second embodiment. The same components as those of the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted here.

  In the fifth embodiment, the photocatalyst layer 52 is provided on the inner surface of the jacket 1 of the processing apparatus 20 of the second embodiment, that is, on the cylindrical inner side wall surface. As the photocatalyst layer 52, for example, titanium oxide having a photocatalytic action can be used. In particular, a photocatalytic layer using titanium oxide grains having a crystal particle diameter of 100 to 500 angstroms is suitable. This is because the photocatalytic layer 52 having high reflectance can be obtained, and the photocatalytic layer 52 also functions as the ultraviolet reflecting surface 8.

  When the titanium oxide of the photocatalyst layer 52 is irradiated with ultraviolet light, a strong oxidation reaction occurs on the surface thereof, and gas and malodorous molecules can be decomposed and deodorized to be changed into harmless substances such as carbon dioxide and water.

  For example, when the processing apparatus 50 of this Embodiment is used for a refrigerator, the to-be-processed water 6 in the tube 3 can be disinfected with the ultraviolet-ray irradiated from the ultraviolet lamp 2. FIG. The treated water 6 is used as ice-making water. At the same time, the freshness of the vegetables stored in the vegetable storage can be maintained. Vegetables stored in the vault are matured quickly due to the self-generated ethylene gas. Ethylene gas, a plant hormone, has the effect of promoting ripening and aging of vegetables and fruits. By irradiating the photocatalyst layer 52 with light having a wavelength of 254 nm of the light emitted from the ultraviolet lamp 2, active species (light energy) are generated on the surface of the photocatalyst layer, and the active species act as an ethylene decomposition photocatalyst. Since the aging hormone ethylene gas can be decomposed into carbon dioxide and water, the freshness of the vegetables can be maintained. The ability to decompose and remove ethylene gas is about 60 times higher by providing the photocatalyst layer 52. By providing the photocatalyst layer 52, it is possible to decompose and remove malodorous components such as ammonia and trimethylamine. Furthermore, when the processing device 50 processes the air in the refrigerator, it is possible to suppress the activity of bacteria (gas floating bacteria) and the like in the warehouse, and to suppress the generation of mold.

  As described above, in the simultaneous gas and liquid cleaning apparatuses 10, 20, 30, 40, and 50 according to the present invention, water sterilization and air purification can be simultaneously performed by one apparatus. Therefore, when both purified water and air are required, such as in a plant factory or a refrigerator, it is not necessary to prepare separate treatment apparatuses for water and air, and the occupied space can be reduced in size.

<Sixth Embodiment>
FIG. 6 is a schematic perspective view showing an example of the configuration of the main part of the processing apparatus 60 according to the sixth embodiment of the present invention. The processing apparatus 60 of the present embodiment includes a cylindrical jacket 61, an ultraviolet lamp 2 inside the jacket 61, a hollow tube 3 that spirally winds the outer periphery of the jacket 61, and a pair of open end portions of the cylindrical jacket. A blower 5 provided on one side of the tube and an infusion device 8 for sending a liquid into the tube. In addition, the same code | symbol is attached | subjected about the structure same as the processing apparatus 10 of 1st Embodiment, and detailed description here is abbreviate | omitted.

  In the sixth embodiment, the jacket 61 is formed of an ultraviolet ray transmitting material such as a quartz tube. Further, the tube 3 is disposed so as to be spirally wound in contact with the outer periphery of the jacket 61.

  When the gas and liquid simultaneous cleaning treatment apparatus 10, 20, 30, 40, 50, 60 according to the present invention is used in, for example, a plant factory or a storage, ethylene gas generated by the plant itself is generated by ultraviolet rays and ozone. It can be decomposed into carbon dioxide and water. The carbon dioxide produced here can be supplied for plant photosynthesis, and it is not necessary to use equipment that requires a large supply of carbon dioxide necessary for plant growth. In addition, ozone has a function of sterilizing surface bacteria simultaneously with the decomposition of ethylene gas. Therefore, it has a great effect on maintaining the freshness of plants. The purified water can be used as a nutrient solution for growing plants.

  The above embodiment is merely an example in all respects. The present invention is not construed as being limited to these descriptions. For example, the present invention includes a jacket having a shape other than a cylinder, such as a rectangular tube or a polygonal tube, a bellows shape that can be bent, and a device that processes a liquid other than water or a gas other than air.

  According to the simultaneous gas and liquid cleaning apparatus according to the present invention, water and the like can be sterilized and air and the like can be simultaneously cleaned with one gas and liquid. In addition, even if the distance between the ultraviolet lamp and the liquid is increased to increase the volume of gas that can be processed, it is possible to suppress the decrease in the liquid purification processing capability. Thereby, various liquid treatments such as industrial wastewater treatment, sewage treatment, clean water treatment, drinking water treatment, organic matter treatment, liquid treatment including organisms such as bacteria, protozoa, etc. where simultaneous cleaning of gas and liquid is desired In the facility, these liquids can be applied to the simultaneous use of odor components, harmful substances such as trichlorethylene, bacteria, etc. in the liquid treatment facility in the air.
