Description

Technical Field

[0001] This application relates to the technical field of urine collection, and particularly to an urban-scale urine collection, storage, and transportation system and method for buildings. Background Art

[0002] The main task of modern sewage treatment plants is to convert nitrogen in sewage into nitrogen gas and phosphorus in sewage into sludge precipitation through biochemical reactions, thereby removing nitrogen and phosphorus elements from sewage. This process consumes a large amount of electricity and chemicals and generates a large amount of sludge that is difficult to treat and even causes secondary pollution.

[0003] Since flush toilets flush feces into the sewer, the proportion of urine in modern urban sewage is less than 1%, but it causes about 80% of the nitrogen and 50% of the phosphorus in sewage. If urine can be separated from sewage at the source, that is, urine does not enter the sewer, the load on sewage treatment plants can be greatly reduced. In fact, urine itself is a complete nutrient solution for plants. The nitrogen, phosphorus, and potassium in a person's urine can provide fertilizer for about 400 square meters of grain or 200 square meters of lawn. Using collected urban urine for agriculture can greatly reduce the use of chemical fertilizers. The vast majority of people in cities live and work in multi-story / high-rise buildings. Installing urine pipelines in newly built buildings will increase a lot of expenses. Moreover, it is almost impossible to install special urine pipelines in the vast majority of existing buildings now.

[0004] Therefore, how to collect urine from buildings (including existing buildings) and send it to a urine treatment center is a problem that needs to be solved by those skilled in the art. Summary of the Invention

Specific embodiments

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] The core of the present application is to provide an urban-scale building urine collection, storage and transportation system and method for collecting urine from buildings (including existing buildings) and sending it to a urine treatment center.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Figure 1 It is a structural diagram of an urban-scale building urine collection, storage and transportation system provided by an embodiment of the present application. Figure 2 It is a structural diagram of a user urine collection and discharge device provided by an embodiment of the present application, as Figure 1 and Figure 2As shown in the figure, the urban-scale building urine collection, storage and transportation system includes: a human presence sensor 1, a user urine collection and discharge device 2, a three-way valve 3, a unit building urine collection device, a urine pumping pump 4 and a control device; the human presence sensor 1 is arranged in the toilet to detect information about the user entering and leaving the toilet. The user urine collection and discharge device 2 includes a catheter 201, a urine collection bucket 202, a urine discharge pipe 203 and a switch valve 204 arranged on the urine discharge pipe 203. The catheter 201 is respectively connected to a waterless urinal 5 and the urine collection bucket 202. The urine discharge pipe 203 is respectively connected to the bottom of the urine collection bucket 202 and a sewage pipe 6. The three-way valve 3 is respectively connected to the sewage pipe 6, the unit building urine collection device and a sewer 7. The unit building urine collection device is connected to a urine treatment center 8 through the urine pumping pump 4. The control device is respectively connected to the human presence sensor 1, the switch valve 204, the three-way valve 3 and the urine pumping pump 4.

[0035] In the embodiment of the present application, the human presence sensor 1 and the user urine collection and discharge device 2 are usually arranged in each toilet in a unit building. The human presence sensor 1 detects information about the user entering and leaving the toilet and uploads the above information to the control device. The embodiment of the present application does not make specific limitations on the control device, which can be a computer, a mobile phone, etc. To facilitate the control device to control the human presence sensor 1 and the switch valve 204 in the unit building and achieve unified management and personalized settings, the human presence sensor 1 and the switch valve 204 are respectively named. The human presence sensors 1 of the entire unit building are WA (WA1, WA2, WA3... WAn). WA1 represents the human presence sensor 1 in the first user urine collection and discharge device 2 in the unit building, and so on. WAn represents the human presence sensor 1 in the nth user urine collection and discharge device 2 in the unit building. The human presence sensors 1 of the entire unit building can be set uniformly. For example, the sensitivity, detection range, etc. of the human presence sensor 1 can be set; the parameters of each human presence sensor 1 can also be set individually and personalized. For example, according to the needs of different toilets, the sensitivity or working mode of the human presence sensor 1 can be adjusted. The switch valves 204 of the entire unit building are WB (WB1, WB2, WB3... WBn). WB1 represents the switch valve 204 in the first user urine collection and discharge device 2 in the unit building, and so on. WBn represents the switch valve 204 in the nth user urine collection and discharge device 2 in the unit building; the switch valves 204 of the entire unit building can be set uniformly, or the parameters of each switch valve 204 can be set individually and personalized.

[0036] Usually, when the human presence sensor 1 detects that any user in the unit building enters the toilet, the switch valves 204 on all the urine discharge pipes 203 in the unit building are controlled to close, and the three-way valve 3 is switched to connect the sewage pipe 9 to the sewer to prevent urine from flowing into the sewer 7 through the sewage pipe 6 and prevent sewage from entering the collection tank 10. As Figure 2As shown in the figure, the user urine collection and discharge device 2 includes a urinary catheter 201, a urine collection bucket 202, a urine discharge pipe 203 and a switch valve 204; the urinary catheter 201 is connected to the waterless urinal 5 and the urine collection bucket 202, and is used to guide urine from the waterless urinal 5 to the urine collection bucket 202. The urinary catheter 201 can be connected to one urine collection bucket 202 and multiple waterless urinals 5 respectively; the urine collection bucket 202 is mainly used for temporarily storing urine; the urine discharge pipe 203 is connected to the bottom of the urine collection bucket 202 and the sewage discharge pipe 6, and is used to discharge urine from the urine collection bucket 202; the switch valve 204 is installed on the urine discharge pipe 203 and is used to control the discharge of urine. The three-way valve 3 is connected to the sewage discharge pipe 6, the urine collection device of the unit building and the sewer 7. By controlling the switching of the three-way valve 3, it is possible to select to discharge urine into the urine collection device of the unit building to avoid discharging urine into the sewer 7. Among them, the sewage discharge pipe 6 and the sewer 7 are existing pipes in the current building. Domestic sewage is directly discharged from the sewage discharge pipe 6 into the sewer 7. A total of n toilets in the unit building share a sewage discharge pipe 6 leading to the sewer 7, and a set of user urine collection and discharge device is set in each toilet.

[0037] The embodiment of the present application does not specifically limit the urine collection device of the unit building, which is mainly used for centrally collecting the urine of the entire unit building. Usually, one urine collection device of the unit building is used to collect the urine in multiple urine collection buckets 202. The urine pumping pump 4 can pump the urine in the urine collection device of the unit building to the urine treatment center 8. The control device is respectively connected to the human presence sensor 1, the switch valve 204, the three-way valve 3 and the urine pumping pump 4, and can open the switch valve 204 and switch the three-way valve 3 during the idle time of the sewage discharge pipe 6 (such as from 2 am to 3 am every day, during this time period, there is generally very little domestic sewage discharge other than urine) to transport the urine in the urine collection bucket 202 to the urine collection device of the unit building through the sewage discharge pipe 6. The specific control method will be further introduced in the embodiments of the following method.

[0038] An urban-scale building urine collection, storage and transportation system provided by an embodiment of the present application includes: a human presence sensor 1, a user urine collection and discharge device 2, a three-way valve 3, a unit building urine collection device, a urine pumping pump 4 and a control device; the human presence sensor 1 is arranged in the toilet for detecting information on the entry and exit of users into and out of the toilet. The user urine collection and discharge device 2 includes a catheter 201, a urine collection bucket 202, a urine discharge pipe 203 and a switch valve 204 arranged on the urine discharge pipe 203. The catheter 201 is respectively connected to a waterless urinal 5 and the urine collection bucket 202. The urine discharge pipe 203 is respectively connected to the bottom of the urine collection bucket 202 and a sewage pipe 6. The three-way valve 3 is respectively connected to the sewage pipe 6, the unit building urine collection device and a sewer 7. The unit building urine collection device is connected to a urine treatment center 8 through the urine pumping pump 4. The control device is respectively connected to the human presence sensor 1, the switch valve 204, the three-way valve 3 and the urine pumping pump 4. When the human presence sensor 1 detects that any user enters the toilet, the control device controls the switch valve 204 on the urine discharge pipe 203 in all user urine collection and discharge devices 2 in the unit building to close, so as to collect the urine in the waterless urinal 5 by using the urine collection bucket 202. At the same time, the three-way valve 3 is switched to connect the sewage pipe 6 with the sewer 7, and other sewage is allowed to enter the sewer 7 to prevent the sewage from entering the collection tank 10; the control device switches the three-way valve 3 and opens the switch valve 204 on the urine discharge pipe 203 during the idle time of the sewage pipe 6, so as to transport the urine stored in the user urine collection and discharge device 2 to the unit building urine collection device, and then transport the urine in the unit building urine collection device to the urine treatment center 8 through a conveying pump. There is no need to reconstruct the building to add a special urine conveying pipeline, and the existing sewage pipe 6 can be directly used to collect urine from the building (including the already built building) and send it to the urine treatment center 8.

[0039] In addition, the present application can separate urine from other sewage as much as possible at the source, and the urine does not enter the sewer 7, greatly reducing the load on the sewage treatment plant; and it can effectively collect urine to facilitate the utilization of useful components in the urine, such as nitrogen, phosphorus, potassium, etc. for fertilizers, thereby improving the resource utilization rate.

[0040] Based on the above embodiment, the catheter 201 of the embodiment of the present application includes a first U-shaped tube 2011 and a second U-shaped tube 2012. The first end of the first U-shaped tube 2011 is connected to the bottom of the waterless urinal 5, the second end of the first U-shaped tube 2011 is connected to the first end of the second U-shaped tube 2012, and the second end of the second U-shaped tube 2012 is connected to the urine collection bucket 202, and the arc opening direction of the first U-shaped tube 2011 is opposite to the arc opening direction of the second U-shaped tube 2012.

[0041] As Figure 2As shown in the figure, the urine collection bucket 202 is located at the bottom of the waterless urinal 5. The first end of the first U-shaped tube 2011 is connected to the bottom of the waterless urinal 5. The arc opening of the first U-shaped tube 2011 faces the waterless urinal 5. The second end of the first U-shaped tube 2011 is connected to the first end of the second U-shaped tube 2012. The second end of the second U-shaped tube 2012 is hermetically inserted into the urine collection bucket 202 through the top of the urine collection bucket 202 and extends to the near bottom of the urine collection bucket 202. The arc opening of the second U-shaped tube 2012 faces the top of the urine collection bucket 202. Urine flows from the bottom of the waterless urinal 5 into the oil seal of the first U-shaped tube 2011; the urine continues to flow into the first end of the second U-shaped tube 2012, passes through the arc part of the second U-shaped tube 2012 again, and further stabilizes the urine flow; finally, the urine flows into the urine collection bucket 202 from the second end of the second U-shaped tube 2012. The catheter 201 forms a double-sealing effect through the combination of two U-shaped tubes with opposite arc openings, further enhancing the anti-odor function; in the drainage system, the phenomenon of anti-siphonage may cause sewage to flow back. This design can effectively prevent the formation of a siphon effect of urine in the pipeline and avoid urine flowing back to the waterless urinal 5 through the opposite arc openings of the two U-shaped tubes; the design of the U-shaped tube can slow down the flow rate of urine, make the urine flow into the urine collection bucket 202 more smoothly, and reduce urine splashing and noise.

[0042] Further, the urine discharge pipe 203 includes a third U-shaped tube 2031, a fourth U-shaped tube 2032, and a fifth U-shaped tube 2033. The first end of the third U-shaped tube 2031 is inserted into the urine collection bucket 202 through the bottom of the urine collection bucket 202 and is connected to the first end of the fifth U-shaped tube 2033. The second end of the third U-shaped tube 2031 is connected to the first end of the fourth U-shaped tube 2032. The second end of the fourth U-shaped tube 2032 is connected to the sewage discharge pipe 6, and the arc opening direction of the third U-shaped tube 2031 is opposite to the arc opening direction of the fourth U-shaped tube 2032; wherein, the arc opening of the third U-shaped tube 2031 faces the bottom of the urine collection bucket 202. The fifth U-shaped tube 2033 is located inside the urine collection bucket 202, and the arc opening of the fifth U-shaped tube 2033 faces the bottom surface of the urine collection bucket 202, that is, the arc opening direction of the fifth U-shaped tube 2033 is opposite to the arc opening direction of the third U-shaped tube 2031. The design of the fifth U-shaped tube 2033 is to prevent the oil seal layer 12 from being discharged from the urine collection bucket 202 when urinating.

[0043] Based on the above embodiments, the urine collection bucket 202 of the embodiment of the present application is equipped with a rotary cleaner 205. The rotary cleaner 205 includes a connector and a nozzle. The connector is rotatably connected to the nozzle, and the nozzle is arranged at the top inside the urine collection bucket 202.

[0044] One end of the connector of the rotary cleaner 205 is used to connect to a water pipe, and the other end of the connector is inserted into the urine collection bucket 202 and rotatably connected to the nozzle. When the liquid sprays out from the nozzle, a reaction force will be generated, which can drive the nozzle to rotate, so that the nozzle can spray the liquid or aerosol (such as clear water, disinfectant or cleaner) in all directions to clean the inner wall of the urine collection bucket 202. This automated cleaning method can reduce the need for manual cleaning. Urine is likely to form dirt on the inner wall of the container. The rotary cleaner 205 can regularly clean the urine collection bucket 202 to prevent the formation and accumulation of dirt and keep the bucket clean. A clean urine collection bucket 202 can effectively reduce the generation of odors, improve the air quality in the toilet, and enhance the user experience. Regular cleaning can eliminate or reduce the growth of bacteria and microorganisms in the urine collection bucket 202 and reduce the health risks. To facilitate the control device control unit building to control the rotary cleaner 205 and achieve unified management and personalized settings, the rotary cleaner 205 is named. The rotary cleaners 205 in the whole unit building are WC (WC1, WC2, WC3... WCn), where WC1 represents the rotary cleaner 205 in the first user urine collection and discharge device 2 in the unit building, and so on. WCn represents the rotary cleaner 205 in the nth user urine collection and discharge device 2 in the unit building; the parameters of the rotary cleaners 205 in the whole unit building can be set uniformly, or the parameters of each rotary cleaner 205 can be set individually and personalized; among them, the parameters of the rotary cleaner 205 include cleaning time, cleaning frequency, etc.

[0045] Based on the above embodiments, a urine dumping port 206 is provided at the top of the urine collection bucket 202 of the embodiment of the present application, and a sealing cover 207 is provided to cover the urine dumping port 206. A support frame 208 is provided at the bottom of the urine collection bucket 202.

[0046] In the embodiment of the present application, the urine dumping port 206 can be used as a urine collection inlet for a waterless toilet, a urinal, a urine basin, etc. The sealing cover 207 is detachably connected to the urine dumping port 206. Specifically, an internal thread is provided on the inner wall of the sealing cover 207, and an external thread is provided on the outer wall of the urine dumping port 206. The sealing cover 207 and the urine dumping port 206 are screwed together through the cooperation of the internal thread and the external thread. By providing the urine dumping port 206, it is convenient for users to pour urine from other containers (such as a portable urinal) into the collection bucket, so as to be applicable to a variety of usage scenarios. The sealing cover 207 is used to cover the urine dumping port 206 to prevent the emission of odors and the entry of bacteria, and at the same time keep the inside of the urine collection bucket 202 clean. The support frame 208 is used to fix the urine collection bucket 202 to ensure its stability during use and prevent it from tipping over due to collision or tilting; at the same time, it also provides an installation space for the urine discharge pipe 203 connected to the bottom of the urine collection bucket 202.

[0047] Based on the above embodiments, the urine collection device for unit buildings in the embodiments of the present application includes a collection pipe 9, a collection tank 10, and an output pipe 11. The collection pipe 9 is respectively connected to a three-way valve 3 and the collection tank 10, and the output pipe 11 is respectively connected to the collection tank 10 and a urine pumping pump 4.

[0048] In the embodiments of the present application, the shape and size of the collection tank 10 are not specifically limited. When the three-way valve 3 is switched to connect the urine collection bucket 202 and the collection pipe 9, the urine in the urine collection bucket 202 flows into the collection tank 10. The collection tank 10 is used to centrally store the urine transported by the urine collection and discharge devices 2 of multiple users in the unit building. The output pipe 11 is connected to the collection tank 10 and the urine pumping pump 4, and the urine pumping pump 4 can transport the urine in the collection tank 10 to the urine treatment center 8 for treatment.

[0049] Based on the above embodiments, an oil seal layer 12 is provided in each of the catheter 201, the urine collection bucket 202, and the collection tank 10 in the embodiments of the present application.

[0050] The oil seal layer 12 is an organic liquid with a specific gravity smaller than that of water, non-toxic, not easily volatile, and insoluble in water, such as genetically modified oil, gutter oil, etc., and is used to seal the urine odor and prevent volatilization. By providing the oil seal layer 12 in the catheter 201, the urine collection bucket 202, and the collection tank 10, the following advantages are achieved: The collected urine contains volatile substances such as ammonia that are likely to produce odors. The oil seal layer 12 can prevent the odors in the urine from spreading to the surrounding environment, which can not only improve the air quality in the bathroom and enhance the user experience, but also effectively retain nitrogen fertilizers. Urine is a good environment for the growth of microorganisms. The oil seal layer 12 can isolate the air, reduce the contact between microorganisms and air, thereby inhibiting the reproduction of microorganisms, reducing the rate of urine deterioration, and reducing the risk of the spread of bacteria and viruses. There may be certain pressure fluctuations in the sewage pipe 6 or the collection tank 10. The oil seal layer 12 can act as a check valve to prevent sewage or odors from flowing back from the sewage pipe 6 or the collection tank 10 to the urine collection bucket 202 or the catheter 201, ensuring the one-way flow of the system and enhancing the stability and reliability of the system.

[0051] Based on the above embodiments, the embodiments of the present application further include an overflow urine pipe 13. The overflow urine pipe 13 is an L-shaped pipe composed of a horizontal pipe and a vertical pipe. The first end of the horizontal pipe is connected to the sewage pipe 6, the second end of the horizontal pipe is hermetically inserted into the collection tank 10 through the side wall of the collection tank 10, the first end of the vertical pipe is integrally connected to the second end of the horizontal pipe, and the second end of the vertical pipe extends to the near bottom of the collection tank 10.

[0052] Such as Figure 1As shown in the figure, the connection between the overflow urine pipe 13 and the sewage discharge pipe 6 is located between the three-way valve 3 and the sewer 7. When the urine level in the collection tank 10 is too high, the excess urine will flow into the sewage discharge pipe 6 through the overflow urine pipe 13 and then directly flow into the sewer 7. Among them, the L-shaped pipe is an integrally formed pipe. By setting the overflow urine pipe 13, when the urine level in the collection tank 10 is too high, the excess urine will be guided to the sewage discharge pipe 6 through the overflow urine pipe 13 and discharged, which can effectively prevent the urine from overflowing from the collection tank 10 and avoid polluting the surrounding environment; the design of the overflow urine pipe 13 provides a safety mechanism for the system. Even in the event of a failure of the urine pumping pump 4 or other abnormal situations, it can ensure that the urine will not accumulate in the collection tank 10, thus protecting the normal operation of the entire system; through the drainage function of the overflow urine pipe 13, the liquid level in the collection tank 10 can be maintained within a reasonable range, ensuring the stable operation of the system and reducing problems such as increased system pressure caused by too high a liquid level. The part of the horizontal pipe inserted into the collection tank 10 needs to ensure good sealing to prevent urine from leaking from the connection, and sealant or special seals can be used to ensure the sealing performance.

[0053] Based on the above embodiments, the collection tank 10 of the embodiment of the present application is further connected with a transmission pipe 14. The transmission pipe 14 is used to connect the collection tank 10 of the urine collection device of another unit building. The transmission pipe 14 is equipped with a delivery pump and a valve, and the collection tank 10 is provided with a liquid level sensor 15. The control device is respectively connected to the delivery pump, the liquid level sensor 15 and the valve.

[0054] The transmission pipe 14 is used to connect the collection tank 10 of this unit building with the collection tank 10 of the urine collection device of another unit building to realize the cross-unit transmission of urine. The delivery pump is installed on the transmission pipe 14 and is used to transport urine from one collection tank 10 to another collection tank 10. The power and flow rate of the delivery pump should be designed according to the transmission distance and urine flow rate requirements to ensure efficient transportation. The valve is installed on the transmission pipe 14 and is operated by the control device according to the signal of the liquid level sensor 15. The liquid level sensor 15 is installed in the collection tank 10 and is used to monitor the urine level in the collection tank 10 in real time. The liquid level sensor 15 can be an ultrasonic liquid level sensor, a float liquid level sensor or a pressure liquid level sensor, etc., which can accurately measure the liquid level and output a signal. The control device is respectively connected to the delivery pump, the liquid level sensor 15 and the valve, and is used to control the start and stop of the delivery pump and the opening and closing of the valve according to the signal of the liquid level sensor 15. Figure 3 A schematic diagram of the connection of a collection tank provided by the embodiment of the present application is as Figure 3 shown. Multiple collection tanks 10 are connected in sequence and then connected to the urine treatment center 8. Of course, the connection method of multiple collection tanks 10 is not limited Figure 3 to this one.

[0055] Figure 4The flowchart of a method for collecting, storing, and transporting urine in urban-scale buildings provided by an embodiment of the present application is as follows: Figure 4 As shown, a method for collecting, storing, and transporting urine in urban-scale buildings is applied to the above-mentioned urban-scale building urine collection, storage, and transportation system, and includes:

[0056] S10: Obtain the information of users entering and leaving the bathroom detected by the human presence sensor.

[0057] S11: When it is detected that a user enters the bathroom, control the switch valve on the urine discharge pipe in the user urine collection and discharge device to close, and switch the three-way valve so that the sewage pipe is connected to the sewer.

[0058] S12: Obtain the preset time period for urine discharge, and within the preset time period, open the switch valve and switch the three-way valve so that the sewage pipe is connected to the unit building urine collection device.

[0059] In step S11, when it is detected that any user enters the bathroom, control the switch valve on the urine discharge pipe in the user urine collection and discharge devices in all bathrooms of the unit building to close, and at the same time switch the three-way valve so that the sewage pipe is connected to the sewer, and the sewage pipe is not connected to the unit building urine collection device, so as to ensure that other sewage except urine can enter the sewer through the sewage pipe.

[0060] In step S12, during the preset time period, that is, the idle time of the sewage pipe, such as the time period from 2 am to 3 am, the switch valve on the urine discharge pipe can be opened, and the three-way valve can be switched so that the sewage pipe is connected to the unit building urine collection device to transport the urine in the user urine collection and discharge device to the unit building urine collection device. Of course, the preset time period can also be other time periods agreed upon with the user, and other sewage except urine should not be discharged through the sewage pipe as much as possible within the preset time period. Outside the preset time period, close the switch valve and switch the three-way valve so that the sewage pipe is connected to the sewer. After the urine in the urine collection bucket is discharged, the rotation cleaner can also be controlled to clean the inner wall of the urine collection bucket, and the spray sewage enters the sewer through the urine discharge pipe and the sewage pipe, close the switch valve, and start the user urine collection for a new day.

[0061] Based on the above embodiment, the embodiment of the present application further includes: obtaining the urine levels in each collection tank detected by each liquid level sensor; transporting the urine in the collection tank corresponding to the urine level reaching the preset level to the collection tank corresponding to the urine level not reaching the preset level; when the urine levels in all collection tanks reach the preset level, turn on the urine pumping pump to transport the urine in the collection tank to the urine treatment center.

[0062] Transfer the urine in collection tank 10 corresponding to the urine level reaching the preset level to the collection tank 10 corresponding to the urine level not reaching the preset level. Specifically, the control device controls the opening of the delivery pump and valve on the transfer pipe 14 connecting the two collection tanks 10. After delivering a certain amount of urine, the urine levels in both collection tanks 10 do not reach the preset level. Each collection tank 10 continues to collect urine in the user urine collection and discharge device 2. When the urine levels in all collection tanks 10 reach the preset level, the urine pumping pump 4 is turned on, and the urine in all collection tanks 10 can be transferred to the urine treatment center 8. When the liquid level of a certain collection tank 10 reaches the preset level, the control device preferentially transfers the urine to the collection tank 10 with a lower liquid level. In this way, the urine can be stored dispersedly in multiple collection tanks 10, extending the storage time of urine in the unit building; through dispersed storage and centralized transportation, the immediate treatment pressure on the urine treatment plant can be reduced.

[0063] A method for collecting, storing, and transporting urine in urban-scale buildings provided by an embodiment of the present application is applied to the above-mentioned urban-scale building urine collection, storage, and transportation system, and includes: obtaining information on the user entering and leaving the bathroom detected by the human presence sensor 1; when it is detected that the user enters any bathroom in the unit building, controlling the closing of the on-off valve 204 on the urine discharge pipe 203 in all user urine collection and discharge devices 2, and switching the three-way valve 3 so that the sewage discharge pipe 6 is connected to the sewer 7; obtaining a preset time period for urine discharge, and opening the on-off valve 204 within the preset time period, and switching the three-way valve 3 so that the sewage discharge pipe 6 is connected to the unit building urine collection device. When the human presence sensor 1 detects that the user enters any bathroom in the unit building, the control device controls the closing of the on-off valve 204 on the urine discharge pipe 203 in all user urine collection and discharge devices 2 to collect the urine in the waterless urinal 5 using the urine collection bucket 202, and switch the three-way valve 3 so that the sewage discharge pipe 6 is connected to the sewer 7; the control device switches the three-way valve 3 and opens the on-off valve 204 on the urine discharge pipe 203 during the idle time of the sewage discharge pipe 6 to transfer the urine stored in the user urine collection and discharge device 2 to the unit building urine collection device, and then transfers the urine in the unit building urine collection device to the urine treatment center 8 through the delivery pump. There is no need to reconstruct the building to add a dedicated urine transfer pipeline, and the existing sewage discharge pipe 6 can be directly used to collect urine from the already built building and send it to the urine treatment center 8.

[0064] To better understand the urban-scale building urine collection, storage, and transportation system and method of the present application, the following is a further introduction. Example: The unit building has a total of n bathrooms, each bathroom is provided with a set of user urine collection and discharge device 2 and a human presence sensor 1, and a common sewage discharge pipe 6 leads to the sewer 7. Each unit building is provided with a set of unit building urine collection device. The collection tanks 10 in the unit building urine collection devices of adjacent unit buildings form a network through the delivery pump and the transfer pipe 14 to send the urine to the urine treatment center 8.

[0065] Each urine collection bucket 202 collects and stores the urine of users every day from waterless urinals, urine pots, chamber pots, waterless toilets, etc. Through a computer or mobile phone to set the program, during the idle time of the sewage pipe 6 (such as from 2 am to 3 am every day), the three-way valve 3 is controlled to switch, so that the sewage pipe 6 is not connected to the sewer 7, and the sewage pipe 6 is connected to the collection tank 10 of the urine collection device in the unit building; at the same time, the switch valve 204 is controlled to open simultaneously or sequentially according to the program, and the urine in each user urine collection and discharge device 2 is sent to the collection tank 10 of the urine collection device in the unit building through the sewage pipe 6. After the urine in the user urine collection and discharge device 2 is discharged within the set time period, the three-way valve 3 is controlled to switch, so that the sewage pipe 6 is connected to the sewer 7, and the sewage pipe 6 is not connected to the collection tank 10 of the urine collection device in the unit building, and the sewage will enter the sewer 7. At the same time, the rotary washer 205 is controlled to start, and the urine collection bucket 202 is automatically sprayed and washed. The sprayed sewage enters the sewer 7 through the urine discharge pipe 203 and the sewage pipe 6. After the spraying is completed, the switch valve 204 is controlled to close, and the urine collection of users for a new day is started. The human presence sensor 1 detects the information of people entering and leaving the bathroom and automatically uploads it to the computer or mobile phone. If the human presence sensor 1 detects that there is someone in any one or several bathrooms, the switch valves 204 of all user urine collection and discharge devices 2 are in the closed state, and the three-way valve 3 is switched so that the sewage pipe 6 is in a connected state with the sewer 7, ensuring that the discharged sewage enters the sewer 7 and does not enter the urine collection device in the unit building. The L-shaped overflow urine pipe 13 is used to drain occasionally excessive urine to the sewer 7. Each unit building urine collection device and the adjacent unit building urine collection devices are connected into a network through the transmission pipe 14 and the delivery pump. Since the urine volume of each unit building is different, the urine volume of each unit building urine collection device can also be adjusted by monitoring the data of the liquid level sensor 15, so that the urine can be stored in each unit building urine collection device for as long as possible, greatly reducing the burden on the urine treatment plant. The urine in the unit building urine collection device can be transported to the urine treatment center 8 through the urine pumping pump 4.

[0066] In order to collect urine separately, the current international practice is to install special urine pipelines. Besides increasing costs, it is only possible to install special urine pipelines in newly built or renovated buildings. For the vast majority of existing inhabited buildings, it is almost impossible to install special urine pipelines in the foreseeable future. The control device in this application switches the three-way valve 3 during the idle time of the sewage pipe 6 and opens the switch valve 204 on the urine discharge pipe 203 to transport the urine stored in the user urine collection and discharge device 2 to the unit building urine collection device, and then transports the urine in the unit building urine collection device to the urine treatment center 8 through a transfer pump. There is no need to renovate the building to add special urine pipelines. The existing sewage pipe 6 can be directly used to collect urine from the building (including existing buildings) and send it to the urine treatment center 8. Using a transfer pump and a transfer pipe, the collection tanks 10 in each unit building urine collection device are connected to transfer the urine to the collection tank 10 with a lower liquid level. In this way, the urine can be stored in the collection tank 10 for as long as possible, greatly reducing the burden on the urine treatment plant. Using a urine pumping pump 4 and a pipeline to send the urine to the urine treatment center 8, there is no need to transport the urine to the urine treatment plant by a tanker truck, improving efficiency. With an oil seal design, the nitrogen loss caused by the smell of urine and ammonia volatilization during the processes of urine collection, transportation, and storage is solved.
