[0002] Medical waste generally refers to waste that is directly or indirectly infectious, toxic, or otherwise hazardous and is generated by various medical and health institutions in the course of medical treatment, prevention, health care, teaching, scientific research, and other related activities. According to the "Medical Waste Management Regulations," there are five major categories of medical waste, which are generally divided into infectious waste, pathological waste, injury waste, pharmaceutical waste, and chemical waste. The existing medical waste treatment method generally involves pre-sorting according to categories such as utensils, cotton yarn, daily food, and experimental organisms. Some glassware or steel products are then sterilized, treated at high temperatures, and crushed. Other medical waste is buried or incinerated. This treatment process is very cumbersome and requires a lot of manpower. Some incompletely sorted waste is prone to secondary pollution, and the treated waste cannot be reused.

[0003] Existing medical waste disposal equipment requires manual packaging operations after it is full, and then the waste is taken out from the collection device after packaging. The operation process is not convenient enough and the operator is likely to be exposed to pollutants.

[0066] like Figure 1As shown, the embodiment of the present invention introduces a medical waste treatment cabin, including a square cabin body, a one-way openable and closed cabin door is provided on the side of the cabin body for allowing people and items to enter and exit the cabin 1; the cabin 1 is divided into two areas, namely a high-temperature steam sterilization area 3 and a waste treatment area 4; a sterilization cart is provided in the cabin 1, which is movably arranged in the cabin 1 and is used to carry medical waste, and the sterilization cart can move between the high-temperature steam sterilization area 3 and the waste treatment area 4; the high-temperature steam sterilization area 3 is used to perform high-temperature steam sterilization treatment on the medical waste carried by the sterilization cart entering; the waste treatment area 4 is used to receive the waste, wastewater, and waste gas generated by the high-temperature steam sterilization treatment area 3 and to carry out sewage treatment.

[0067] This setup allows medical waste to be freely moved between the sterilization and waste disposal areas using a trolley, significantly improving waste transfer efficiency and effectively increasing waste disposal efficiency. Furthermore, this setup allows for the sterilization of medical waste using high-temperature steam and the classified discharge of sterilized waste, significantly improving waste disposal efficiency. This equipment prevents contamination of the sterilization chamber by medical waste, significantly reducing the difficulty of cleaning the sterilization chamber.

[0068] In the embodiment of the present invention, a sterilization trolley is movably mounted within the shelter 1 for carrying medical waste. A transfer platform is provided behind the door of the shelter 1, on the side of the open door of the high-temperature steam sterilization chamber 31. The top of the transfer platform is a smooth square platform for placing the sterilization trolley and transferring the sterilization trolley between the high-temperature steam sterilization chamber 31 and the crusher 411. The square platform of the transfer platform is positioned slightly higher than the lowest position within the high-temperature steam sterilization chamber 31, so that when the sterilization trolley is placed on the square platform, the sterilization trolley can be pulled out of or pushed into the high-temperature steam sterilization chamber 31.

[0069] In the embodiment of the present invention, the sterilization trolley is made of stainless steel, and directional pulleys are provided at the four corners of the bottom of the sterilization trolley. The directional pulleys face the direction of entry and exit of the high-temperature steam sterilization chamber 31. The width, height and diagonal length of the sterilization trolley are all smaller than the inner diameter length of the high-temperature steam sterilization chamber 31. The length of the sterilization trolley is less than half of the high-temperature steam sterilization chamber 31, so that at least two sterilization trolleys can be accommodated in the high-temperature steam sterilization chamber 31 at the same time, which increases the disposable processing space and is conducive to pushing and pulling, reducing the difficulty of operation.

[0070] In the embodiment of the present invention, the high-temperature steam sterilization chamber 31 is a sterilization chamber with a hollow interior and controllable sealing. The high-temperature steam sterilization chamber 31 is set to have an openable and closable opening on the side facing the cabin door, and a corresponding sealed sterilization chamber door is provided at the opening for sealing the high-temperature steam sterilization chamber.

[0071] In an embodiment of the present utility model, the high-temperature steam sterilization chamber 31 is controllably connected to the steam control system and the vacuum system, so that after the medical waste to be processed is placed in the high-temperature steam sterilization chamber 31, the user starts the working program, and the steam control system and the vacuum system vacuum the inside of the high-temperature steam sterilization chamber 31 so that the high-temperature steam sterilization chamber 31 is in a vacuum. Then, the steam control system increases the temperature and supplies high-temperature steam to the high-temperature steam sterilization chamber 31, thereby achieving the purpose of high-temperature sterilization.

[0072] In the embodiment of the present utility model, the high-temperature steam sterilization area 3 includes a high-temperature steam sterilization chamber 31, which has a closed space for the sterilization cart to enter and exit; a steam supply device 32, whose steam outlet is connected to the high-temperature steam sterilization chamber 31, and is used to supply saturated steam with adjustable temperature and pressure into the high-temperature steam sterilization chamber 31; an exhaust device 33, whose vacuum port is connected to the high-temperature steam sterilization chamber 31, and is used to exhaust the high-temperature steam sterilization chamber 31 and adjust the vacuum degree in the high-temperature steam sterilization chamber 31.

[0073] In the embodiment of the present invention, the steam supply device 32 includes:

[0074] The steam generator 321 has a water inlet connected to a water source via a water softener 322, and is used to supply the inlet water to the steam generating chamber of the steam generator 321 after softening; a heater is provided in the steam generating chamber, and the heater heats the inlet water in the chamber to generate steam; the steam generating chamber is connected to a steam outlet via a pipeline, and is used to output the generated steam to the outside; a pressure regulating valve is provided on the pipeline connected to the steam outlet, and is used to adjust the pressure of the output steam; at the same time, a thermostat is also provided on the pipeline connected to the steam outlet, and is used to adjust the temperature of the output steam; and a control valve is also provided on the pipeline connected to the steam outlet, and is used to control the on and off of the output steam.

[0075] In the embodiment of the present invention, the high-temperature steam sterilization chamber 31 is also provided with an exhaust port and a drain port, which are respectively connected to the waste gas treatment device 43 and the waste water treatment device 42, so that the waste gas and waste water in the high-temperature steam sterilization chamber 31 are treated by the waste gas and waste water treatment devices before being discharged to the outside.

[0076] In the embodiment of the present utility model, the exhaust device 33 can be any existing structure, such as a suction pump, a negative pressure pump, etc. In this embodiment, the exhaust device 33 includes a jet vacuum pump 331, which is connected to the steam generator 321 via a pipeline. The steam flow flowing through the jet vacuum pump 331 generates a negative pressure at the negative pressure suction port of the jet vacuum pump 331; the negative pressure suction port is connected to the high-temperature steam sterilization chamber 31, so that the negative pressure extracts the gas in the high-temperature steam sterilization chamber 31 to adjust the vacuum degree in the high-temperature steam sterilization chamber 31.

[0077] Medical waste disposal methods include the following steps:

[0078] The medical waste is sent to the high-temperature steam sterilization chamber 31 and the high-temperature steam sterilization process is carried out: the high-temperature steam sterilization chamber 31 is pre-evacuated, filled with steam and heated to the set temperature, and sterilization is started and continued for the set time. After the sterilization is completed, the steam and water are exhausted by vacuuming, and then dry air is filled in for drying.

[0079] After the high-temperature steam sterilization process is completed, the waste, waste water and waste gas in the high-temperature steam sterilization chamber 31 are subjected to waste treatment process, waste gas treatment process and waste water treatment process respectively before being discharged.

[0080] Specifically, the packaged medical waste is transported into the high-temperature steam sterilization chamber 31 through a sterilization trolley. The high-temperature steam sterilization chamber 31 is pre-vacuumed, and the air in the high-temperature steam sterilization chamber 31 is extracted to reach the set temperature. The set vacuum degree range is between -0.1MPa and -0.05MPa. Preferably, the vacuum pressure reaches the set vacuum degree -0.09MPa, and then steam is filled to heat it to the set temperature. The set temperature range is 120℃-140℃, preferably, the set temperature is 135℃, and the pressure is maintained at the set pressure. The set pressure range is 0.1MPa-0.3MPa. Preferably, the set pressure The pressure is 0.22MPa, and the sterilization time is started and continued for the set time, the set time range is 45min-60min, preferably, the set time is 45min; after the sterilization is completed, the air is exhausted and the water is drained to make the pressure reach the set pressure, the set pressure range is 20kPa-50kPa, preferably, the set pressure is 30kPa; after the process is completed, vacuum is again performed for the drying treatment stage to make the pressure reach the set pressure, the set pressure range is between -0.1MPa and -0.04MPa, preferably, the set pressure is -0.05MPa. After the drying is completed, the air is introduced to break the vacuum and complete the sterilization process.

[0081] After the sterilization treatment is completed, the sealed door is opened, the sterilization trolley is pulled out, and the sterilization trolley is transported to the elevator. The elevator pours the medical waste in the sterilization trolley into the crusher 411 to crush the medical waste and realize the volume reduction function at the same time. The medical waste after treatment is collected and packaged; the wastewater generated during the treatment process is disinfected by an ultraviolet sterilizer and then discharged, wherein the ultraviolet sterilizer can be an ultraviolet disinfection lamp 421, etc.; the waste gas passes through the spray tower 431 to absorb and settle ammonia, hydrogen sulfide, particulate matter, etc. in the waste gas, and at the same time cools the high-temperature waste gas, and then separates the gas and liquid through the gas-liquid separator; then the possible residual microorganisms in the waste gas are filtered for a second time through the biological filter 433, and finally the odor and particulate matter are absorbed by the high-efficiency adsorber 432, and discharged through the exhaust pipe after treatment; wherein the high-efficiency adsorber 432 can be an activated carbon adsorption tower, etc.

[0082] Among them, the high-temperature steam sterilization process includes:

[0083] (1) Pre-vacuum stage:

[0084] Medical waste enters the high-temperature steam sterilization chamber 31. After the door is closed, the air in the high-temperature steam sterilization chamber 31 is extracted to reach the set vacuum degree;

[0085] Fill the high-temperature steam sterilization chamber 31 with high-pressure steam, and the dryness value of the steam should not be lower than the set dryness value;

[0086] Among them, this embodiment provides two vacuuming modes. Mode one is the pulsating vacuum mode. When the pulsating vacuum mode is adopted, the vacuuming procedure needs to be repeated three to four times; Mode two is the pre-vacuum mode. When the pre-vacuum mode is adopted, the vacuuming procedure only needs to be repeated once.

[0087] Specifically, after the medical waste enters the inner cavity of the high-temperature steam sterilization chamber 31 and the door closes and automatically inflates to seal, the pulsating vacuum stage begins. Because the sterilization medium is saturated steam, interference from non-condensable gases such as air must be eliminated. First, most of the air is evacuated to achieve a certain vacuum level, and then high-pressure steam is introduced. To ensure that more than 99% of the air in the inner cavity is completely expelled, that is, all locally enclosed areas within the inner cavity, such as medical waste packaging bags, are destroyed, the vacuuming process should be repeated three to four times, ensuring that the non-condensable gas content does not exceed 3.5%, the overheating does not exceed 5°C, and the steam dryness value does not fall below 0.95. This ensures that the high-pressure steam can more easily penetrate the material, allowing for more complete contact between the material and the steam, ultimately ensuring effective sterilization. The gas discharged during the pulsating vacuum stage must be filtered and adsorbed for harmless treatment before it can be discharged. This ensures that the discharged gas meets the relevant standards for both medical hygiene and environmental protection.

[0088] (2) Heating stage:

[0089] Start to continuously fill the high-temperature steam sterilization chamber with steam until the temperature in the high-temperature steam sterilization chamber 31 reaches the set temperature;

[0090] Specifically, vacuuming should be repeated three to four times, and then steam should be continuously added until the temperature reaches 135°C and the sterilization stage begins.

[0091] (3) Sterilization stage:

[0092] The sterilization timer starts, during which the high-temperature steam sterilization chamber is kept at the set temperature to thoroughly sterilize the medical waste;

[0093] Until the sterilization timer reaches the set time, the program will turn to the exhaust stage;

[0094] Specifically, the sterilization timer starts, during which the steam regulating valve is controlled by temperature and pressure to ensure that the inner chamber is kept within a certain temperature range to sterilize the waste. When the temperature is lower than 135°C, steam filling continues. When the temperature is higher than 135°C, steam filling is stopped. After the sterilization timer reaches 45 minutes, the program switches to the steam exhaust stage.

[0095] (4) Exhaust stage:

[0096] The exhaust port of the high-temperature steam sterilization chamber 31 is opened, and the steam in the high-temperature steam sterilization chamber 31 is discharged under the action of the internal and external pressure difference; after the air pressure in the high-temperature steam sterilization chamber 31 drops to the set value, the program switches to the drying stage;

[0097] Specifically, the pneumatic butterfly valve at the exhaust port opens, and the steam is discharged under the action of the internal and external pressure difference; after the pressure drops to the set value, the program switches to the drying stage.

[0098] (5) Drying stage:

[0099] The gas in the high-temperature steam sterilization chamber 31 is extracted, and the vacuum degree in the high-temperature steam sterilization chamber 31 drops to the set vacuum degree and is maintained for the set time, and the drying stage ends;

[0100] Specifically, the drying phase begins with a strong vacuum, maintaining a certain vacuum level for 5 minutes. Air is then introduced to complete the drying process. The entire process is automatically controlled by the program, requiring no human intervention. Upon completion, an audible and visual alarm signals the end of sterilization. The main control system, comprised of control components such as pressure transmitters, pressure controllers, and temperature transmitters, transmits signals to the PLC, which in turn sends signals to control valves, the switching of vacuum and pipeline pumps, and other functions, thereby enabling the program to run automatically.

[0101] (6) Finally, air flows into the high-temperature steam sterilization chamber, and the high-temperature steam sterilization process is completed.

[0102] The medical waste treatment cabin introduced in the embodiment of the present invention is also provided with a waste treatment area 4; the waste treatment area 4 is provided with waste, waste gas and wastewater treatment devices 41, 43, 42 to respectively treat the solid waste, gaseous waste gas and liquid wastewater treated in the high-temperature steam sterilization area 3, and discharge the treated wastes in different forms separately, thereby achieving the effect of thoroughly sterilizing and disinfecting the medical waste.

[0103] In the embodiment of the present utility model, the waste treatment area 4 includes:

[0104] The waste treatment device 41 has a space for the sterilization trolley to dump the medical waste after high-temperature steam sterilization, and is used to crush the dumped waste;

[0105] The exhaust gas treatment device 43 is connected to the exhaust port of the high-temperature steam sterilization chamber 31 and is used to sterilize and disinfect the exhaust gas discharged from the high-temperature steam sterilization chamber 31;

[0106] The wastewater treatment device 42 is connected to the drain outlet of the high-temperature steam sterilization chamber 31 and is used to sterilize and disinfect the wastewater discharged from the high-temperature steam sterilization chamber 31 .

[0107] In the embodiment of the present invention, the waste treatment device 41 includes a crusher 411 and a transmission structure. The transmission structure extends from the high-temperature steam sterilization chamber 31 to the crusher 411 and is used to drive the sterilization cart from the high-temperature steam sterilization chamber 31 to the crusher 411. After the medical waste to be treated has been sterilized at high temperature in the high-temperature steam sterilization chamber 31, the high-temperature steam sterilization chamber 31 is opened, the sterilization cart is pulled out, and the sterilization cart is sent to the transmission structure. The transmission structure lifts the sterilization cart to the crusher 411; the waste inside the sterilization cart is then poured into the crusher 411, which crushes the medical waste after high-temperature sterilization to achieve the volume reduction function of the medical waste.

[0108] Waste treatment processes include:

[0109] After the high-temperature steam sterilization chamber 31 is opened, the medical waste sterilized by high-temperature steam is poured into the crusher 411 for crushing;

[0110] The medical waste after crushing is transported to the compression baler, and the packaged waste is transported to the container garbage truck, which then transports it to the landfill for disposal.

[0111] This equipment adopts the process sequence of sterilization before crushing, which can avoid the spread of bacteria in medical waste before treatment and meet the requirements of changes in medical waste treatment volume; the process of sterilization before crushing is widely used, the process technology is mature, the treatment process is safe, the treatment effect is guaranteed, and there is no risk of infection; the system has high reliability and can ensure long-term stable operation; it does not require high operating skills, and operation, maintenance and care are relatively simple; it is recommended by the standard and is the mainstream treatment process.

[0112] In the embodiment of the present utility model, the exhaust gas treatment device 43 includes:

[0113] The spray tower 431 is connected to the exhaust port of the high-temperature steam sterilization chamber 31. A coolant is sprayed downward from the top of the spray tower 431. The exhaust gas discharged from the high-temperature steam sterilization chamber 31 flows upward through the spray tower 431 and exchanges with the coolant, thereby adsorbing and removing large particles of hydrogen sulfide, ammonia and other gases in the exhaust gas.

[0114] The gas-liquid separator 434 has an air inlet connected to the top air outlet of the spray tower 431 to separate the exhaust gas into gas and liquid;

[0115] The air inlet of the biofilter 433 is connected to the air outlet at the top of the spray tower 431, and the biofilter membrane is used to filter the residual viruses in the exhaust gas;

[0116] The air inlet of the high-efficiency adsorber 432 is connected to the air outlet of the biological filter 433, and the air outlet is connected to the outside atmosphere. The activated carbon filter element is used to adsorb and remove hydrogen sulfide and ammonia gases in the exhaust gas and then discharge them into the atmosphere.

[0117] Spray tower 431 has a tower body through which coolant sprays downward. Exhaust gases generated during high-temperature steam sterilization, exhaust after high-temperature steam sterilization, and dry vacuum exhaust are all discharged to spray tower 431. Circulating spray water washing in spray tower 431 effectively traps substances such as ammonia and hydrogen sulfide in the exhaust gas. It also cools the exhaust gas, lowers its temperature, removes water vapor, and reduces the volume of exhaust gas discharged. Furthermore, for small particles that cannot be trapped, activated carbon is used for adsorption. These molecules are relatively small, making activated carbon a more effective adsorption method. Furthermore, to effectively dispose of any uninactivated microorganisms that may be present in the exhaust gas, a high-efficiency filter membrane is used to filter the exhaust gas and thoroughly treat the pathogenic microorganisms.

[0118] The bottom of the spray tower 431 is equipped with a trough to collect the coolant flowing downward from the tower. A circulation pipeline is connected to the trough at one end and to the top of the tower at the other end. The circulation pipeline is equipped with a circulation pump to circulate the coolant between the tower and the trough. The coolant flowing through the spray tower 431 can be any liquid. In this embodiment, water is preferably used as the coolant to reduce costs.

[0119] A drain port is provided at the bottom of the spray tower for actual drainage of the spray tower, and an overflow port is provided on the side of the spray tower for overflow drainage of the spray tower;

[0120] Part of the actual drainage from the spray tower 431 is disinfected, and the other part is reused by the spray tower 431 after heat exchange in the cooler.

[0121] Waste treatment area 4 also includes:

[0122] The exhaust gas absorption device 44 includes two air suction hoods 441 respectively provided above the high-temperature steam sterilization chamber 31 and the crusher 411. The air suction ports of the air suction hoods 441 are suspended in the cabin 1 and are used to absorb the exhaust gas overflowing from the high-temperature steam sterilization chamber 31 and the crusher 411.

[0123] The air outlets of the two air suction hoods 441 are connected to the pipeline between the biological filter 433 and the high-efficiency adsorber 432.

[0124] Waste gas treatment processes include:

[0125] The waste gas generated during the high-temperature steam sterilization process first passes through the spray tower 431. The spray water circulates in the spray tower 431 to absorb and settle the ammonia and hydrogen sulfide in the waste gas, and at the same time cools the high-temperature waste gas.

[0126] The waste gas is then passed through the gas-liquid separator 434 for gas-liquid separation;

[0127] The waste gas then passes through the biofilter 433, where the high-efficiency filter membrane in the biofilter 433 thoroughly filters the uninactivated microorganisms in the waste gas.

[0128] Finally, the exhaust gas flows through the high-efficiency adsorber 432 , and the substances with smaller molecules in the exhaust gas are adsorbed by the activated carbon in the high-efficiency adsorber 432 .

[0129] The waste gas treatment process also includes:

[0130] The waste gas overflowing from the high-temperature steam sterilization chamber 31 and the crusher 411 is absorbed by the waste gas absorption device 44;

[0131] The absorbed waste gas is adsorbed by the high-efficiency adsorber 432 .

[0132] Furthermore, spray water circulates in the spray tower 431 and sprays downward;

[0133] A liquid collecting tank is provided at the bottom of the spray tower to collect the spray water;

[0134] The liquid outlet of the collecting tank is connected to the liquid inlet at the top of the spray tower 431 through a pipeline equipped with a circulation pump, so that the collected spray water flows back to the top of the spray tower and then sprays downward to form a circulating flow;

[0135] The waste gas enters the spray tower 431 from the air inlet at the bottom and flows out from the air outlet at the top. The waste gas flows from bottom to top in the spray tower 431 and comes into contact with the spray water during the flow, so that the ammonia and hydrogen sulfide in the waste gas are absorbed into the spray water, and the waste gas is cooled.

[0136] Specifically, the vacuuming and exhausting during the sterilization process, the exhausting after sterilization, and the exhausting during the drying process are all discharged to spray tower 431 via a pneumatic butterfly valve and a jet vacuum pump. The circulating spray water wash effectively captures substances such as ammonia and hydrogen sulfide in the exhaust gas, while also cooling the water vapor and reducing the volume of the exhaust gas. For small amounts of gases that cannot be captured, activated carbon is used for adsorption. These molecules are relatively small, making activated carbon a more effective adsorption method. To effectively dispose of any uninactivated microorganisms that may be present in the exhaust gas, a high-efficiency filter membrane is used to filter the exhaust gas and thoroughly remove the pathogenic microorganisms.

[0137] This project utilizes a combination of spraying, filtration, and adsorption as its primary treatment process. When discharging waste gas, spray tower 431 utilizes a packed tower. Gas enters from the bottom, liquid sprays down from the top, fully contacting the upward-flowing gas before the gas is discharged from the top of spray tower 431. A liquid collection tank is located at the bottom of the tower, where the coolant is recycled. The wastewater is regularly discharged and disinfected with ultraviolet light to kill pathogenic microorganisms.

[0138] Steam enters the spray tower, where it combines with liquid to form soluble substances in the exhaust gas, forcing organic matter into the water tank, thereby removing odor from the exhaust gas. The high-temperature exhaust gas passes through biofilter 433, which filters out pathogenic microorganisms. The filter membrane has a pore size of 0.2rm and a filtration efficiency of over 99.999%.

[0139] After being filtered, the exhaust gas is sent into the high-efficiency adsorber 432 by the induced draft fan. The hydrogen sulfide and ammonia gases in the exhaust gas are further removed through adsorption and interception by activated carbon, so that the exhaust gas meets the emission standards.

[0140] In this embodiment, the wastewater treatment device 42 includes a wastewater sterilizer, which is arranged on the wastewater drainage pipe and has an ultraviolet disinfection lamp 421, which uses the ultraviolet rays generated by the ultraviolet disinfection lamp 421 to irradiate and disinfect the wastewater flowing through; a sewage treatment station, and the outlet of the wastewater drainage pipe is connected to the sewage treatment station to discharge the discharged wastewater to the sewage treatment station for sewage treatment after ultraviolet sterilization and disinfection.

[0141] In an embodiment of the present utility model, in the wastewater treatment device 42, the drainage of the high-temperature steam sterilization chamber 3, the drainage of the spray tower 431, the condensed water of the gas-liquid separator 434, the condensed water of the silencer 5, and the condensed water of the biological filter 433 are all connected through pipelines and collected into the front-end pipeline of the ultraviolet disinfection lamp 421. When discharged, they are disinfected by the ultraviolet disinfection lamp 421 and then discharged, completely inactivating the microorganisms in the wastewater. After treatment, the wastewater can be directly collected into the wastewater treatment pipeline for discharge; a silencer 5 is connected in series in the pipeline to reduce the whistling sound generated during vacuum extraction; the silencer 5 is arranged between the gas-liquid separator 434 and the biological filter 433.

[0142] The drainage of the high-temperature steam sterilization chamber involves the drainage of the high-temperature steam sterilization chamber 31 during the treatment process and the drainage after sterilization; the drainage of the spray tower 431 involves the overflow drainage of the spray tower 431 and the actual drainage of the spray tower;

[0143] In the embodiment of the present invention, the air outlet of the high-efficiency adsorber 432 is connected to the outside atmosphere through an exhaust pipe provided with a fan 6, and the exhaust end of the exhaust pipe passes through the cabin 1, which is used to discharge the exhaust gas in the cabin 1 into the atmosphere after being treated to meet the emission standards.

[0144] The water source 2 of the present application can provide the steam generator 321 and the spray tower 431 with water for evaporation and water for spraying.

[0145] The high-temperature steam sterilization process, waste treatment process, wastewater treatment process and exhaust gas treatment process of this application are all processed in the same cabin;

[0146] The air outlet of the high-efficiency adsorber is connected to the atmosphere outside the cabin through an exhaust pipe with a fan, and is used to discharge the treated gas that meets the emission standards into the atmosphere.
