Description

Technical Field

[0001] The present invention relates to the field of manufacturing and application technology of environmental protection, energy saving, recycling, human excrement treatment and sewage treatment equipment for specific places, including mobile or fixed places, and in particular to a system or device for rapid harmless treatment and discharge of human excrement, sewage and malodorous gases in multiple toilets used in places such as transport vehicles, tourist attractions, large indoor and outdoor gathering places, areas of public health emergencies, urban streets, squares, parks, factories and mines, oil fields, military camps, field work sites, stations, docks, and residential areas, which is clean, colorless, odorless, free of secondary pollution, and leaves no trace and meets emission standards; the present invention also relates to the technology of food waste treatment. Background Art

[0002] The environmentally friendly discharge of passenger waste is a major issue plaguing the passenger transport sector and remains a major technological challenge facing the world. Current applications for enclosed toilets, whether used on roads, railways, aircraft, or ships, primarily include vacuum-retaining toilets, compact vacuum toilets, circulating toilets, and pressure-flush toilets. These enclosed toilets currently serve only to collect waste and do not perform any treatment while the vehicle is in motion. Instead, waste is emptied from the collection tanks at designated stations, passenger depots, depots, airports, and passenger terminals via dedicated unloading trucks or fixed, ground-based emptying equipment. This waste is then either transported directly to municipal wastewater treatment plants or treated in local septic tanks or anaerobic ponds before being discharged into the municipal sewage network.

[0003] Treatment of wastewater from long-distance passenger transport toilets is challenging due to its high concentrations of organic matter, ammonia nitrogen, and suspended solids. According to national environmental protection requirements, water discharged into municipal pipe networks must meet the "Water Quality Standard for Sewage Discharge into Urban Sewers" (CJ 343-2010). To meet these requirements, in addition to biological treatment, dilution is also required, requiring significant water volumes. Furthermore, my country's urban sewage treatment infrastructure is underdeveloped. Many depots and passenger stations lack access to appropriate urban pipe networks. Discharging into municipal pipe networks requires significant investment, while the amount of fecal wastewater that can be accommodated is limited. Using unloading trucks to transport wastewater to municipal sewage treatment plants is insufficient to meet current passenger transport needs.

[0004] In addition, including but not limited to aviation toilets, vehicle-mounted trailer-type mobile toilets, and ground-mounted environmentally friendly toilets, all have the following common characteristics:

[0005] 1. Most human excrement is only collected, and feces and urine are not treated, let alone discharged in compliance with standards. They are basically no different from traditional toilets and cannot achieve zero pollution and meet discharge standards.

[0006] 2. Most of the excrement is not separated into solid and liquid, and the excrement and liquid coexist, making subsequent treatment difficult;

[0007] 3. The capacity of the waste box / storage box is limited. When the waste box / storage box is full of waste, it must be unloaded. Otherwise, the toilet must be shut down, causing on-site environmental pollution and inconvenience in use.

[0008] 4. During the suction, discharge and transportation process, sewage trucks will emit a large amount of odor, which will have a negative impact on the environment. Therefore, there are still local pollution and safety risks.

[0009] 5. The sewage collected by the toilet is centrally treated on the ground, which requires a large amount of surface water for dilution treatment. The cost is high and requires huge manpower, financial resources and material resources.

[0010] 6. Special equipment is required for sewage unloading, which has high manpower and equipment investment costs and a large maintenance workload. In addition, the treatment of feces and urine occupies social resources and increases the pressure on urban sewage and wastewater treatment;

[0011] In summary, the market does not provide a complete set of net-discharge, mobile and sewer-free toilet technology solutions to meet the development needs of passenger technology. Therefore, it is necessary to develop innovative designs based on this. Summary of the Invention

DETAILED DESCRIPTION

[0057] The following describes embodiments of the present invention in conjunction with the accompanying drawings, but should not be limited to the following embodiments:

[0058] Please refer to the accompanying drawings of the present invention. The features of the subsystems of the mobile multi-seat WC system assembly are as follows:

[0059] The toilet seat usage subsystem includes: a toilet bowl 1, a toilet bowl flushing nozzle 2 supplied with water by a flush valve of an air-water control device 177 through a toilet flushing water pipe 178, a toilet bowl flushing water supply pipe system 3, a feces and sewage dropper 5, and a toilet bowl full liquid level switch 4. This subsystem serves as the primary human-machine interface. The toilet bowl 1 receives human excrement. After excretion is completed, the flush button 173 is pressed. The feces collection subsystem, under the control of the intelligent electronic control device 172 and the air-water control device 177 of the air source subsystem, controls the air pipe 179 through the first discharge valve to open the quick discharge valve 7. Under the vacuum pressure within the waste collection box 9, feces and sewage are quickly sucked into the waste collection box 9. As the quick discharge valve 7 opens, the toilet bowl flushing water supply pipe system 3 supplies water at a certain pressure, causing the toilet bowl flushing nozzle 2 to spray water, flushing the toilet bowl 1.

[0060] When the toilet bowl 1 is full of feces, the toilet bowl full level switch 4 outputs a toilet bowl flushing instruction, and the execution process of this instruction is consistent with the toilet bowl flushing instruction issued by the flush button 173;

[0061] The feces collection subsystem includes: a quick discharge valve 7, a waste collection box 9, and a feces emptying valve 18. The main body of the waste collection box 9 is cylindrical and can repeatedly withstand a certain negative pressure and positive pressure. The box body is provided with a feces inlet 12, a feces outlet 13, an inspection port 16, a vacuum suction port 11 connected to the waste collection box vacuum pipe 180 controlled by the air and water control device 177, a positive pressure air supply port 14 connected to the waste collection box positive pressure inflation pipe 181 controlled by the air and water control device 177, a first full liquid level sensor 15, a first discharge pipe 6, a second discharge pipe 8, and a third discharge pipe 17.

[0062] When the intelligent electronic control device 172 detects that the toilet in the toilet use subsystem is unoccupied, that is, the flush button 173 is not pressed, the air and water control device 177 of the air source subsystem issues a vacuuming command, and the vacuum generator therein starts working to draw the waste collection box 9 to a certain vacuum level, and keeps the vacuum level within a certain range. The vacuum pressure switch within the air and water control device 177 is used to control the upper and lower limits of the vacuum level range (which can be set to -10KPa to -25KPa). When the vacuum level in the waste collection box 9 drops below -10KPa, the ejector automatically starts working to draw the vacuum level in the waste collection box 9 until the vacuum level reaches -25KPa, at which point the ejector automatically stops working. The waste collection box 9, which maintains a certain vacuum pressure range, is ready for flushing the toilet bowl 1.

[0063] When the first full level sensor 15 of the waste collection box 9 detects that the feces and sewage collected in the waste collection box 9 are full, it sends an instruction to empty the waste collection box 9 to the intelligent electronic control device 172. At this time, it will temporarily shield and store the flushing instruction of the toilet bowl 1, so that the quick drain valve 7 remains closed. At the same time, it sends an emptying instruction to the waste collection box 9, so that the waste collection box emptying solenoid valve in the air-water control device 177 of the wind source subsystem is actuated to provide 0.3MPa of compressed air to the waste collection box 9. At the same time, the second drain valve controlled by the air-water control device 177 controls the air pipe 182 to open the feces and sewage emptying valve 18 to force the sewage to flow out. The waste collection box 9 is emptied; the volume of the waste collection box 9 remains unchanged, so its emptying time is limited. After the set time, the waste collection box emptying solenoid valve and the feces and sewage emptying valve 18 in the air-water control device 177 of the wind source subsystem are closed at the same time, and the waste collection box 9 is automatically transferred to the vacuum program. After the vacuum pressure in the waste collection box 9 meets the set requirements, the intelligent electronic control device 172 will first detect whether there is a flushing instruction for the temporarily shielded bedpan 1. If so, the bedpan 1 cleaning process will be executed immediately. If not, the flushing instruction for the bedpan 1 will be detected, and the waste collection box 9 will be kept in a vacuum negative pressure state.

[0064] The solid-liquid separation subsystem includes: a solid-liquid separation box 20, a sewage inlet 23, a heavy phase solid outlet 24, a precipitated sewage outlet 27, a supernatant outlet 28, a sewage overflow outlet 29, a sewage return inlet 30, a first odor exhaust outlet 31, a self-cleaning primary filter assembly 35, a self-cleaning secondary filter assembly 32, a discharge filter plate 25, a primary filter flushing compressed air supply port 34, a secondary filter flushing compressed air supply port 33, a full liquid level switch 21, a half liquid level switch 47, a low liquid level switch 26, a low dirt switch 22, a sewage inlet pipe 19, a heavy phase solid Outlet pipe 10, heavy phase solid discharge valve 36, sedimentation liquid outlet pipe 41, sedimentation liquid stop valve 42, sedimentation liquid pipe 43, sedimentation liquid discharge valve 44, supernatant liquid outlet pipe 112, supernatant liquid stop valve 113, supernatant liquid pipe 114, supernatant liquid pipe conveying solenoid valve 115, sewage overflow pipe 111, sewage return pipe 123, second odor discharge pipe 98, primary filter flushing compressed air supply pipe 184, secondary filter flushing compressed air supply pipe 185, heavy phase solid conveying pipe 37, sedimentation liquid conveying pipe 45, solid pipeline collecting tee 38.

[0065] After the feces emptying valve 18 of the feces collection subsystem is opened, the feces with a certain pressure in the waste collection box 9 are directly discharged into the solid-liquid separation box 20 through the feces inlet pipe 19. The feces with a certain pressure are filtered twice in the solid-liquid separation box 20 by the self-cleaning primary filter component 35 and the self-cleaning secondary filter component 32 to separate the heavy phase feces (which may contain a certain amount of toilet paper, other block / lump items accidentally left behind by the user, etc., hereinafter referred to as "solids") and urine (including flushing water, hereinafter referred to as "black water"), and the solids with larger particle size remain in the solid cavity, the solids with smaller particle size and black water flow into the liquid cavity and are precipitated in the liquid cavity, and the black water enters the supernatant cavity.

[0066] The solid chamber, liquid chamber, and supernatant chamber of the solid-liquid separation box 20 are all designed to be V-shaped, with a wide top and narrow bottom. To quickly concentrate the solids in the solid chamber, the filter plate 25 in the solid chamber is designed to form a certain angle with the bottom of the box to facilitate the concentration of the solids. The concentrated solids are retained above the heavy phase solid outlet 24.

[0067] After the primary filtration, the black water enters the liquid chamber and then passes through the self-cleaning secondary filter assembly 32 for secondary filtration. Particles with relatively large sizes remain in the liquid chamber, while the black water flows into the supernatant chamber. Since both the liquid chamber and the supernatant chamber are designed to be V-shaped with a wide top and narrow bottom, after the waste collection box 9 is emptied, the feces and sewage emptying valve 18 is closed, and the primary filtration is basically completed, the fluidity of the black water decreases, and flocculent solids with a certain particle size slowly settle in the lower part of the liquid chamber, while the black water remains as the supernatant in the upper part of the liquid chamber and the supernatant chamber.

[0068] The self-cleaning primary filter assembly 35 and the self-cleaning secondary filter assembly 32 are both designed with special mesh and box-type structures to improve the filtration efficiency of the solid-liquid separation system:

[0069] A: Whenever the dirt in the solid chamber is lower than the low dirt switch 22, before the dirt is discharged from the receiving dirt collection box 9, the intelligent electronic control system 172 will send a cleaning instruction to the air-water control device 177, and the compressed air supply pipe 184 will be used to blow the self-cleaning primary filter assembly 35 with constant pressure and high pressure air through the primary filter to prepare for the next solid-liquid separation.

[0070] B: Whenever the black water in the liquid chamber is lower than the low liquid level switch 26, the intelligent electronic control system 172 will send a cleaning instruction to the air-water control device 177. The compressed air supply pipe 185 will flush the self-cleaning secondary filter assembly 32 with constant pressure high-pressure air to prepare for the next solid-liquid separation.

[0071] After the manure emptying valve 18 is closed for a certain period of time, the supernatant pipe conveying solenoid valve 115 is opened, and the first electric booster pump 117 of the heat exchange subsystem starts to work, and the supernatant with a certain pressure after pressurization is conveyed to the anode-free photocatalytic treatment urine subsystem through the heat exchanger 147 for treatment; when the low liquid level switch 26 of the solid-liquid separation subsystem detects that the liquid level is low, the low liquid level switch 26 is activated, and the first electric booster pump 117 of the heat exchange subsystem stops working.

[0072] The sedimentation liquid stop valve 42 and the supernatant liquid stop valve 113 are open when the solid-liquid separation subsystem is operating normally, and are only manually turned to the closed position when the system is under maintenance or fails;

[0073] During the process of sending the black water in the liquid chamber and the supernatant chamber of the solid-liquid separation box 20 to the electrodeless photocatalytic urine treatment subsystem for treatment, as the liquid level decreases, the half-liquid level switch 47 is actuated, and the third discharge valve controlled by the gas-water control device 177 controls the air pipe 183 to open the heavy phase solid discharge valve 36, and the solids retained above the heavy phase solid outlet 24 are discharged through the heavy phase solid discharge valve 36, the heavy phase solid delivery pipe 37, and the solid pipeline collection tee 38. The solids are sent through the solids conveying pipe 39 to the microwave incineration subsystem's reamer sewage pump 40 for shredding and conveying until the solids drop to the detection position of the low-contamination switch 22. The low-contamination switch 22 is then actuated, and all the solids in the solids chamber are discharged. Thereafter, the heavy-phase solids discharge valve 36 is closed. During this stage, the feces and sewage emptying valve 18 remains closed until the self-cleaning primary filter assembly 35 completes self-cleaning, allowing the sewage collection box 9 to be emptied again.

[0074] A certain amount of black water is stored under the drain filter plate 25 to ensure proper fluidity of the solid matter.

[0075] After the solids in the solid cavity are emptied and the heavy phase solid discharge valve 36 is closed, the sediment discharge valve 44 is opened, and the sediment in the liquid cavity is sent by gravity through the sediment delivery pipe 45 and the solid pipeline collecting tee 38 to the microwave incineration subsystem's reamer sewage pump 40. The reamer sewage pump 40 is properly cleaned, and at the same time, the sediment that is not suitable for being sent to the electrodeless photocatalytic urine treatment subsystem is also sent to the microwave incineration subsystem.

[0076] The odor in the solid-liquid separation box 20 is sent to the electrodeless photocatalytic treatment waste gas subsystem through the first odor exhaust port 31, the second odor exhaust pipe 98, the first odor pipeline tee 155, the third odor delivery pipe 99, the second odor pipeline tee 156, and the fourth odor delivery pipe 100 through the axial flow fan 102 of the electrodeless photocatalytic treatment waste gas subsystem for odor decomposition treatment;

[0077] In a multi-toilet system, taking into account the uneven use of toilets, the volume of the solid-liquid separation box 20 is optimized to reduce the volume of equipment and rationally utilize resources. Therefore, it cannot be ruled out that when the solid-liquid separation box 20 receives the feces and sewage from the waste collection boxes 9 of several toilets (such as three toilets in a six-toilet system) one after another, due to the large amount of black water, the anode-free photocatalytic urine treatment subsystem cannot process it in time, resulting in a large amount of black water retention. Therefore, a sewage overflow port 29 is provided to allow the black water to be temporarily discharged into the residual liquid tank 124 through this port and the sewage overflow pipe 111 for temporary storage;

[0078] The microwave incineration subsystem includes: a sewage pump with a reamer 40, a coarse pulp box 49, an electric crusher 54, a fine pulp box 56, a first self-priming pump 61, a fine pulp preheating box 63, a first stop valve 83, a second self-priming pump 85, an incineration electric valve 89, and a microwave incinerator 71; wherein:

[0079] A. The brown stock box 49 is provided with a brown stock receiving port 48, a second brown stock conveying pipe 53, a second full liquid level sensor 51, a first low liquid level sensor 52, a second odor exhaust port 50, and a first brown stock conveying pipe 46;

[0080] The reamer sewage pump 40 shreds the solids and sediments sent from the solid-liquid separation subsystem and feeds them into the rough stock box 49 through the first rough stock delivery pipe 46. When there is a certain amount of rough stock in the rough stock box 49, the first low liquid level sensor 52 is activated, and the rough stock flows into the electric pulverizer 54 through the second rough stock delivery pipe 53, which starts the operation.

[0081] The odor generated in the brown stock box 49 is sent to the electrodeless photocatalytic treatment waste gas treatment subsystem through the second odor exhaust port 50, the first odor conveying pipe 94, the odor tee 154, the second odor conveying pipe 97, the first odor pipeline tee 155, the third odor conveying pipe 99, the second odor pipeline tee 156, the fourth odor conveying pipe 100, and the axial flow fan 102 of the electrodeless photocatalytic treatment waste gas treatment subsystem for odor decomposition treatment;

[0082] The second full liquid level sensor 51 of the brown stock box 49 is mainly used to alarm that the brown stock box 49 is full;

[0083] B. The receiving port of the electric pulverizer 54 is directly connected to the coarse stock box 49 through the second coarse stock conveying pipe 53, and receives the coarse stock flowing into the coarse stock box 49. After the electric pulverizer is started, the coarse stock is further crushed and ground, and then conveyed to the fine stock box 56 for transfer through the first fine stock conveying pipe 55;

[0084] C. The fine pulp box 56 is provided with a first fine pulp delivery pipe 55, a first fine pulp outlet 59, a third full liquid level sensor 57, a second low liquid level sensor 58, and a first fine pulp outlet pipe 60;

[0085] The fine pulp after being crushed and ground by the electric pulverizer 54 falls directly into the fine pulp box 56 by gravity, and flows into the first self-priming pump 61 through the first fine pulp output port 59 and the first fine pulp output pipe 60;

[0086] When the fine slurry box 56 is full of fine slurry, the third full liquid level sensor 57 is activated, and the first self-priming pump 61 is started to pump the fine slurry into the fine slurry preheating box 63. After the first self-priming pump 61 is working, the fine slurry in the fine slurry box 56 gradually decreases. When the fine slurry level is low enough to trigger the second low liquid level sensor 58, the first self-priming pump 61 stops working, and all the fine slurry in the fine slurry box 56 is transferred to the fine slurry preheating box 63.

[0087] The third full liquid level sensor 57 of the fine pulp box 56 is mainly used for alarming that the fine pulp box 56 is full and for starting control of the first self-priming pump 61;

[0088] D. The fine slurry preheating box 63 is provided with a fine slurry inlet 67, a flue 76, a flue outlet 77, a third odor exhaust outlet 96, a second fine slurry outlet 75, a flue gas inlet pipe 70, a fourth full liquid level sensor 64, a half liquid level sensor 65, a third low liquid level sensor 66, a ring heater 69, a temperature control sensor 68, a second fine slurry delivery pipe 62, a first odor exhaust pipe 95, a flue gas exhaust pipe 107, a second fine slurry delivery pipe 82, a first stop valve 83, a third fine slurry delivery pipe 84, a second self-priming pump 85, a fourth fine slurry delivery pipe 86, a second three-way valve 87, a fifth fine slurry delivery pipe 88, an incineration electric valve 89, and a fine slurry input pipe 90;

[0089] The fine slurry sucked from the fine slurry box 56 by the first self-priming pump 61 is delivered to the fine slurry preheating box 63 through the second fine slurry delivery pipe 62 and the fine slurry inlet 67. When the fine slurry level is higher than the third low liquid level sensor 66, the third low liquid level sensor 66 is activated, and the annular heater 69 starts to work. The temperature control sensor 68 is used to detect the temperature of the fine slurry and control the operation of the annular heater 69 through the intelligent control system.

[0090] The annular heater 69 only plays an auxiliary role in the preheating process of the fine pulp preheating box 63. When the microwave incinerator 71 has not yet started and the fine pulp has been pumped from the fine pulp box 56 to the fine pulp preheating box 63, the fine pulp is mainly preheated by the power supply of the annular heater 69. When the microwave incinerator 71 is working, the high-temperature hot steam after the solid incineration treatment and the high-temperature exhaust gas after combustion pass through the flue 76 in the fine pulp preheating box 63 to heat the fine pulp at the same time. When the fine pulp temperature reaches the preset temperature, the intelligent control system issues a stop command to the annular heater 69 to stop it. After that, the preheating of the fine pulp is entirely carried out by the high-temperature hot steam after the solid incineration treatment and the high-temperature exhaust gas after combustion.

[0091] After the first self-priming pump 61 is started, the fine slurry it draws from the fine slurry box 56 is delivered to the fine slurry preheating box 63 through the second fine slurry delivery pipe 62 and the fine slurry inlet 67. When the fine slurry level is higher than the half-level sensor 65 and the fine slurry reaches the preset temperature, the second self-priming pump 85 is started to deliver the preheated fine slurry to the atomizing nozzle inlet 74 of the microwave incinerator 71 through the second fine slurry outlet 75, the second fine slurry outlet pipe 82, the first stop valve 83, the third fine slurry delivery pipe 84, the second self-priming pump 85, the fourth fine slurry delivery pipe 86, the second three-way valve 87, the fifth fine slurry delivery pipe 88, the incineration electric valve 89, and the fine slurry input pipe 90.

[0092] When the microwave incinerator 71 is in operation, the high-temperature hot steam generated after the solid incineration treatment and the high-temperature exhaust gas after combustion are preheated to the fine pulp through the flue 76 in the fine pulp preheating box 63, and then mixed with the high-temperature hot steam discharged from the electrodeless photocatalytic urine treatment subsystem through the flue port 77 and the flue gas discharge pipe 107 through the third tee 108, and then sent to the heat exchanger 147 through the high-temperature gas delivery pipe 109 to preheat the black water sent to the electrodeless photocatalytic urine treatment subsystem;

[0093] E. The microwave incinerator 71 is provided with an atomizing nozzle input port 74, a first compressed air input port 73, an ash discharge port 72, and a flue gas inlet pipe 70;

[0094] The fine slurry preheated in the fine slurry preheating box 63 is pressurized by the second self-priming pump 85 and then sent to the atomizing nozzle of the microwave incinerator 71. It is atomized and dried in the microwave incinerator 71 and incinerated in the incineration area. The ash after incineration is temporarily stored above the ash discharge port 72 and will be cleaned and discharged when conditions permit.

[0095] The air-water control device 177 delivers fresh air at a certain pressure to the microwave incinerator 71 through the compressed air delivery pipe 78, the first three-way connection 79, the microwave incinerator air inlet pipe 80, and the first compressed air inlet 73. This air is used to assist combustion and to stir the dried solids in the drying zone of the microwave incinerator to ensure complete combustion. In addition, the compressed air blows the high-temperature steam generated in the microwave incinerator 71 and the high-temperature exhaust gas after combustion into the fine pulp preheating box 63 through the flue gas inlet pipe 70 to preheat the fine pulp.

[0096] The electrodeless photocatalytic urine treatment subsystem includes: an electrodeless photocatalytic urine treatment device 132, a high-temperature supernatant liquid input pipe 119, a compressed air input pipe 81, a waste liquid discharge pipe 120, and a high-temperature steam discharge port 133, wherein the electrodeless photocatalytic urine treatment device 132 is provided with: an atomizing nozzle 135, a supernatant liquid input port 134, a second compressed air input port 137, a waste liquid discharge port 136, and a high-temperature steam discharge port 133;

[0097] To ensure the normal operation of the system, as an auxiliary system, a set of residual liquid storage devices is added to the electrodeless photocatalytic urine treatment subsystem, including a residual liquid tank 124, an overflow liquid discharge port 127 of the solid-liquid separation subsystem, an untreated supernatant liquid discharge port 128 of the electrodeless photocatalytic urine treatment subsystem, a system cleaning waste liquid discharge port 129, a residual liquid tank cleaning waste liquid discharge port 131, a residual liquid output port 126, a first residual liquid delivery pipe 121, a second electric booster pump 122, a cleaning waste water delivery pipe 91, an electric valve 92 for flushing waste liquid, a drain pipe 196, a second stop valve 197, a fifth full liquid level sensor 125, and a fourth low liquid level sensor 130;

[0098] After the excrement emptying valve 18 is closed for a certain period of time, the electrodeless photocatalytic urine treatment device is started for preheating, the supernatant pipe conveying solenoid valve 115 in the solid-liquid separation device is opened, and the first electric booster pump 117 of the heat exchange subsystem works to convey the supernatant with a certain pressure after supercharging through the supernatant input pipe 118, the heat exchanger 147, and the supernatant input port 134 to the atomizing nozzle 135 of the electrodeless photocatalytic urine treatment device for microwave electrodeless photocatalytic degradation and sterilization treatment;

[0099] During the degradation process of the supernatant, a large amount of high-temperature steam (containing a certain amount of odor, the same below) will be generated. This steam will be sent into the heat exchange system together with the pressurized air sent by the air source subsystem and the high-temperature flue gas generated by the microwave incineration system to heat the supernatant input system. The high-temperature steam is transported in the following order: the electrodeless photocatalytic urine treatment device 132, the high-temperature steam outlet 133, the third three-way connection 108, the high-temperature gas delivery pipe 109, and the heat exchanger 147;

[0100] The air-water control device 177 delivers fresh air with a certain pressure to the electrodeless photocatalytic urine treatment device 132 through the compressed air delivery pipe 78, the first three-way connection 79, the compressed air input pipe 81, and the second compressed air input port 137. On the one hand, it can stir the mist liquid sprayed from the atomizing nozzle 135 of the electrodeless photocatalytic urine treatment device 132 to fully degrade it, and on the other hand, it promotes the discharge of high-temperature water vapor after degradation, which is beneficial to the circulation of water vapor.

[0101] Since the supernatant is not fully preheated during the startup of the electrodeless photocatalytic urine treatment device 132 and the microwave incineration system, part of the atomized water will still fall into the liquid collecting area at the bottom of the electrodeless photocatalytic urine treatment device 132 in the form of supernatant, and will be sent back to the residual liquid tank 124 through the waste liquid outlet 136 and the waste liquid discharge pipe 120 of the electrodeless photocatalytic urine treatment device 132, and finally return to the supernatant chamber of the solid-liquid separation system;

[0102] The residual liquid tank 124 collects and stores:

[0103] A. The supernatant overflowing from the solid-liquid separation system is discharged through the solid-liquid separation tank 20, the dirty liquid overflow port 29, the dirty liquid overflow pipe 111, the solid-liquid separation subsystem overflow liquid discharge port 127, and the residual liquid tank 124 for temporary storage;

[0104] B. Part of the atomized water of the electrodeless photocatalytic urine treatment device 132 falls into the lower liquid collection area of ​​the electrodeless photocatalytic urine treatment device 132 in the form of the supernatant liquid, and is sent back to the residual liquid tank 124 through the waste liquid outlet 136 of the electrodeless photocatalytic urine treatment device 132, the waste liquid discharge pipe 120, and the untreated supernatant liquid outlet 128;

[0105] C. System flushing water return: The sewage generated during the system flushing process is discharged through the fine pulp preheating box and then sent to the residual liquid tank 124 through the second fine pulp output port 75, the second fine pulp output pipe 82, the first stop valve 83, the third fine pulp delivery pipe 84, the second self-priming pump 85, the fourth fine pulp delivery pipe 86, the second three-way valve 87, the cleaning sewage delivery pipe 91 (the incineration electric valve 89 is closed when the flushing procedure is performed), the flushing sewage electric valve 92, the flushing sewage delivery pipe 93, and the system cleaning sewage discharge port 129.

[0106] The waste liquid stored in the residual liquid tank 124 is sent to the liquid chamber of the solid-liquid separation device 20 through the second electric booster pump 122. The delivery path is:

[0107] The residual liquid tank 124, the residual liquid outlet 126, the first residual liquid delivery pipe 121, the second electric booster pump 122, the dirty liquid return pipe 123, and the dirty liquid return inlet 30 return the liquid to the liquid chamber of the solid-liquid separation device 20; the activation of the second electric booster pump 122 is controlled by the fifth full liquid level sensor 125. When the second electric booster pump 122 is activated, it pumps the residual liquid to lower the liquid level of the residual liquid tank 124. When the fourth low liquid level sensor 130 is activated, the second electric booster pump 122 stops operating.

[0108] If the residual liquid tank 124 needs to be cleaned, or the entire system needs to be shut down, the dirty liquid in the residual liquid tank 124 can be completely drained. The process is as follows:

[0109] When the second stop valve 197 is opened, the dirty liquid in the residual liquid tank 124 is discharged through the residual liquid tank cleaning drain outlet 131, the second stop valve 197, the second residual liquid delivery pipe 198, the four-way valve 146, the fifth drain pipe 193, and the drain joint 194; the drain joint 194 adopts a fire pipe joint specially used for the fire protection system, which can be connected to the nearby sewage well through the fire pipe to discharge the cleaning sewage directly into the urban sewage pipe.

[0110] The electrodeless photocatalytic waste gas treatment subsystem includes: an electrodeless photocatalytic waste gas treatment device 105, an axial flow fan 102, a waste gas input pipe 103, a waste gas input port 104, and a clean gas discharge port 106;

[0111] The odor from the solid-liquid separation subsystem and microwave incineration subsystem, as well as the high-temperature steam and flue gas that have not yet been completely liquefied produced by the electrodeless photocatalytic treatment urine subsystem after heat exchange, are fed into the electrodeless photocatalytic treatment waste gas treatment device 105 through the axial flow fan 102, the waste gas input pipe 103, and the waste gas input port 104. After the organic gas is deodorized and degraded by photochemical reaction, it is discharged from the clean gas outlet 106.

[0112] The heat exchange subsystem includes: a heat exchanger 147, a high-temperature flue gas inlet 149, a flue gas outlet 148, a supernatant liquid inlet 150, a high-temperature supernatant liquid outlet 151, a second reclaimed water outlet 152, a high-temperature gas delivery pipe 109, a flue gas output pipe 101, a supernatant liquid input pipe 118, a high-temperature supernatant liquid input pipe 119, a first reclaimed water output pipe 153, and a first electric booster pump 117;

[0113] When the microwave incinerator 71 is working, the high-temperature hot steam generated after the incineration of the solid matter and the high-temperature exhaust gas after combustion are preheated to the fine pulp through the flue 76 in the fine pulp preheating box 63, and then mixed with the high-temperature hot steam output pipe 110 discharged from the electrodeless photocatalytic urine treatment subsystem through the flue port 77 and the flue gas discharge pipe 107 through the third tee 108, and then sent to the heat exchanger 147 through the high-temperature gas delivery pipe 109 and the high-temperature flue gas inlet 149 to heat exchange the black water sent to the electrodeless photocatalytic urine treatment subsystem, and then mixed with the odor through the flue gas outlet 148, the flue gas output pipe 101, the second odor pipeline tee 156, and then sent to the electrodeless photocatalytic waste gas treatment subsystem through the axial flow fan 102 for deodorization and degradation of organic gas, and then discharged from the clean gas outlet 106;

[0114] After the excrement emptying valve 18 is closed for a certain period of time, the electrodeless photocatalytic urine treatment device is started for preheating, the supernatant pipe conveying solenoid valve 115 in the solid-liquid separation device is opened, and the first electric booster pump 117 of the heat exchange subsystem works to pressurize the supernatant from the solid-liquid separation box 20, the supernatant outlet 28, the supernatant outlet pipe 112, the supernatant stop valve 113, the supernatant pipe 114, the supernatant conveying solenoid valve 115, the supernatant conveying pipe 116, the first electric booster pump 117, and the supernatant input pipe 118 and send it into the heat exchanger 147 for heat exchange and heating, and then through the high-temperature supernatant input pipe 119 and the supernatant input port 134 to the atomizing nozzle 135 of the electrodeless photocatalytic urine treatment device for microwave electrodeless photocatalytic degradation and sterilization treatment;

[0115] The high-temperature steam generated by the microwave incinerator, the high-temperature exhaust gas after combustion, and the high-temperature steam discharged from the anode-free photocatalytic urine treatment subsystem are heat-exchanged with the normal-temperature supernatant output from the solid-liquid separation tank 20 in the heat exchanger 147, and the water in the high-temperature steam is condensed and precipitated. The generated reclaimed water falls into the funnel-shaped reclaimed water storage area at the bottom of the heat exchanger, and then falls into the reclaimed water tank 138 through the first reclaimed water output pipe 153 for storage in preparation for reclaimed water reuse.

[0116] The flue gas after heat exchange in the heat exchanger 147 is sent to the electrodeless photocatalytic treatment waste gas treatment subsystem through the heat exchanger flue gas outlet 148, the flue gas output pipe 101, the second odor pipeline tee 156, the fourth odor conveying pipe 100 and the axial flow fan 102 of the electrodeless photocatalytic treatment waste gas treatment subsystem for odor decomposition treatment.

[0119] When the grey water level in the grey water tank 138 reaches a certain level and the sixth full level sensor 141 on the grey water tank 138 is activated, the grey water pump 166 starts to operate, pumping the grey water in the grey water tank 138 through the first grey water outlet 142, the second grey water output pipe 167, the grey water pump 166, and the grey water inlet pipe 165 into the clean water tank 157 for flushing. When the grey water level in the grey water tank 138 drops to the point where the fifth low level sensor 143 is activated, or when the water level in the clean water tank 157 rises and the seventh full level sensor 158 of the clean water tank 157 is triggered, the grey water pump 166 stops operating.

[0120] When the system is used for the first time or is used again after being out of service for a period of time, the clean water tank 157 must first be filled with clean water from a surface water source;

[0121] When the water tank 138 is filled with grey water, the excess grey water is discharged through the first overflow port 140, the first overflow pipe 144, the cross-connect 146, the fifth drain pipe 193, and the drain connector 194. The drain connector 194 is a fire-fighting pipe connector specially designed for the fire-fighting system. It can be connected to a nearby sewage well through a fire-fighting pipe to discharge the cleaning wastewater directly into the city sewage pipe.

[0122] Before the system is shut down, the second drain plug 190 allows the grey water in the grey water tank 138 to be drained through the drain connector 194.

[0124] When the system is used for the first time or is restarted after being out of service for a period of time, the clean water tank 157 must first be filled with clean water from a surface water source.

The clean water connector 164 uses a fire pipe connector specially designed for the fire protection system, and clean water can be directly introduced through the fire pipe interface.

[0125] When the grey water accumulates to a certain level and the sixth full level sensor 141 on the grey water tank 138 is activated, the grey water pump 166 starts to operate, pumping the grey water in the grey water tank 138 through the first grey water outlet 142, the second grey water output pipe 167, the grey water pump 166, and the grey water inlet pipe 165 into the clean water tank 157 for flushing the toilet;

[0126] When someone uses the toilet, the flush button 173 is pressed. Under the control of the intelligent electronic control device 172 of the intelligent control subsystem and the air-water control device 177 of the air source subsystem, the feces collection subsystem powers on and opens the flush solenoid valve in the air-water control device 177. Compressed air flows through the flush solenoid valve, one way into the flush valve, opening it, and the other way into the water booster through the quick exhaust valve, pressurizing the flush water. The pressurized water then flows through the flush valve into the toilet bowl 1, flushing the toilet bowl 1. After the flushing process is complete, the flush solenoid valve loses power and closes, closing the flush valve. The flushing water (recycled water or clean water) flows through the clean water tank 157, the water outlet 159, and the water pipe 168 before entering the air-water control device 177.

[0134] Based on the overall description of the embodiments of the present invention, the following embodiments are provided:

[0135] Example 1:

[0136] like Figure 1 、 Figure 2As shown, the toilet bowl 1 is provided with a toilet flushing nozzle 2 inside and a toilet flushing water supply pipe system 3 outside. The bottom is a feces and sewage drop port 5, and the toilet bowl full liquid level switch 4 is provided inside the toilet bowl. The toilet bowl 1 receives human excrement. After excretion is completed, the flush button 173 is operated. The feces collection subsystem opens the quick discharge valve 7 under the control of the intelligent electronic control device 172 of the intelligent control subsystem and the air and water control device 177 of the air source subsystem. Under the action of the vacuum pressure in the waste collection box 9, the feces and sewage are quickly sucked into the waste collection box 9. At the same time as the quick discharge valve 7 is opened, the toilet flushing water supply pipe system 3 supplies water at a certain pressure, causing the toilet flushing nozzle 2 to spray water to flush the toilet bowl 1. The duration of the flushing process can be set to 2 seconds.

[0137] When the toilet bowl 1 is full of feces, the toilet bowl full liquid level switch 4 outputs a toilet bowl flushing instruction, and the execution process of this instruction is consistent with the toilet bowl flushing instruction issued by the flush button 173.

[0138] Example 2:

[0139] On the basis of Example 1, Figure 1 、 Figure 3 As shown: the main body of the dirt collection box 9 is cylindrical and can repeatedly withstand a certain negative pressure and positive pressure.

[0140] Example 3:

[0141] On the basis of Example 1 and Example 2, Figure 1 、 Figure 4 As shown: the solid-liquid separation box 20 is divided into three inner chambers: a solid chamber, a liquid chamber, and a supernatant chamber.

[0142] The self-cleaning primary filter assembly 35 and the self-cleaning secondary filter assembly 32 are both designed with special mesh and box-type structures to improve the filtration efficiency of the solid-liquid separation system:

[0143] A certain amount of black water is stored at the bottom of the drain filter plate 25 to ensure proper fluidity of the solid matter.

[0144] Example 4:

[0145] Based on Examples 1 to 3, Figure 1 、 Figure 5 As shown: the sewage pump 40 with a reamer chops up the solids and sediments sent from the solid-liquid separation subsystem and sends them into the crude pulp box 49 through the first crude pulp conveying pipe 46. When there is a certain amount of crude pulp in the crude pulp box 49, the first low liquid level sensor 52 is activated, and the crude pulp flows into the electric pulverizer 54 through the second crude pulp conveying pipe 53 and starts working.

[0146] Example 5:

[0147] On the basis of Example 1 to Example 4, Figure 1 、 Figure 6 As shown, the fine pulp crushed and ground by the electric grinder 54 falls directly into the fine pulp box 56 by gravity, and flows into the first self-priming pump 61 through the first fine pulp output port 59 and the first fine pulp output pipe 60.

[0148] Example 6:

[0149] On the basis of Example 1 to Example 5, Figure 1 、 Figure 7 As shown: the fine pulp sucked from the fine pulp box 56 by the first self-priming pump 61 is sent into the fine pulp preheating box 63 through the second fine pulp conveying pipe 62 and the fine pulp inlet 67. The temperature control sensor 68 is used to detect the temperature of the fine pulp and control the operation of the ring heater 69 through the intelligent control system.

[0150] Example 7:

[0151] Based on Examples 1 to 6, Figure 1 、 Figure 8 As shown: the fine slurry preheated in the fine slurry preheating box 63 is pressurized by the second self-priming pump 85 and then sent to the atomizing nozzle of the microwave incinerator 71, where it is atomized and dried and incinerated in the incineration area. The ash after incineration is temporarily stored above the ash discharge port 72 and will be cleaned and discharged when conditions permit.

[0152] Air-water control device 177 delivers fresh air at a certain pressure to microwave incinerator 71 via compressed air delivery pipe 78, first T-joint 79, microwave incinerator air inlet pipe 80, and first compressed air inlet 73. This air not only aids combustion but also stirs the dried solids in the microwave incinerator's drying zone for complete combustion. Furthermore, the compressed air blows the high-temperature steam generated within microwave incinerator 71 and the high-temperature exhaust gases from combustion through flue gas inlet pipe 70 into the fine slurry preheating tank 63 to preheat the fine slurry.

[0153] Example 8:

[0154] On the basis of Example 1 to Example 3, Figure 1 、 Figure 9 As shown: after the manure emptying valve 18 is closed for a certain period of time, the electrodeless photocatalytic urine treatment device is started for preheating, the supernatant pipe conveying solenoid valve 115 in the solid-liquid separation device is opened, and the first electric booster pump 117 of the heat exchange subsystem works to convey the supernatant with a certain pressure after pressurization through the heat exchanger 147, the high-temperature supernatant input pipe 119, and the supernatant input port 134 to the atomizing nozzle 135 of the electrodeless photocatalytic urine treatment device for microwave electrodeless photocatalytic degradation and sterilization treatment.

[0155] A large amount of high-temperature steam (containing a certain amount of odor, the same below) will be generated during the degradation process of the supernatant. These steam will be sent into the heat exchange system together with the pressurized air sent in by the wind source system and the high-temperature flue gas generated by the microwave incineration system to heat the supernatant input system. The transportation path of the high-temperature steam is: the anode-less photocatalytic urine treatment device 132, the high-temperature steam exhaust outlet 133, the third three-way 108, the high-temperature gas transmission pipe 109, and the heat exchanger 147.

[0156] The air-water control device 177 supplies fresh air with a certain pressure to the electrodeless photocatalytic urine treatment device 132 through the compressed air delivery pipe 78, the first three-way valve 79, the compressed air input pipe 81, and the second compressed air input port 137. On the one hand, it can stir the liquid sprayed from the atomizing nozzle of the electrodeless photocatalytic urine treatment device 132 to fully degrade it. On the other hand, it promotes the discharge of high-temperature water vapor after degradation, which is beneficial to the circulation of water vapor.

[0157] Since the supernatant is not fully preheated during the startup of the electrodeless photocatalytic urine treatment device and the microwave incineration system, part of the atomized water will still fall into the lower liquid collection area of ​​the electrodeless photocatalytic urine treatment device in the form of supernatant, and be sent back to the residual liquid tank 124 through the waste liquid outlet 136 and the waste liquid discharge pipe 120 of the electrodeless photocatalytic urine treatment device 132, and finally return to the supernatant chamber of the solid-liquid separation system.

[0158] Example 9:

[0159] On the basis of Examples 1 to 3 and 8, Figure 1 、 Figure 10 As shown: the residual liquid tank 120 collects and stores:

[0160] The supernatant overflowing from the solid-liquid separation system flows through the solid-liquid separation box 20, the dirty liquid overflow port 29, the dirty liquid overflow pipe 111, the solid-liquid separation subsystem overflow liquid discharge port 127 and is discharged into the residual liquid box 120 for temporary storage.

[0161] Part of the atomized water of the electrodeless photocatalytic urine treatment device will fall into the lower liquid collection area of ​​the electrodeless photocatalytic urine treatment device in the form of supernatant liquid, and will be sent back to the residual liquid tank 124 through the waste liquid outlet 136 of the electrodeless photocatalytic urine treatment device 132, the waste liquid outlet pipe 120, and the untreated supernatant liquid outlet 128.

[0162] Example 10:

[0163] On the basis of Example 1 to Example 8, Figure 1 、 Figure 11As shown: when the microwave incinerator 71 is working, the high-temperature hot steam generated after the incineration of the solid matter and the high-temperature exhaust gas after combustion are preheated to the fine pulp through the flue 76 in the fine pulp preheating box 63, and then mixed with the high-temperature hot steam output pipe 110 discharged from the electrodeless photocatalytic urine treatment subsystem through the flue port 77 and the flue gas exhaust pipe 107 through the third tee 108, and then sent to the heat exchanger 147 through the high-temperature flue gas input pipe 109 and the high-temperature flue gas inlet 149 to heat exchange the black water sent to the electrodeless photocatalytic urine treatment subsystem, and then mixed with the odor through the flue gas outlet 148, the flue gas output pipe 101, the second odor pipeline tee 156, and then sent to the electrodeless photocatalytic waste gas treatment subsystem through the axial flow fan 102 for deodorization and degradation of organic gas, and then discharged from the clean gas outlet 106.

[0164] The high-temperature hot steam generated by the microwave incinerator, the high-temperature exhaust gas after combustion, and the high-temperature hot steam discharged from the anode-less photocatalytic urine treatment subsystem are heat exchanged with the normal-temperature supernatant output from the solid-liquid separation box 20 in the heat exchanger 147. The moisture in the high-temperature hot steam is condensed and washed out to produce grey water, which falls into the funnel-shaped grey water storage area at the bottom of the heat exchanger and then falls into the grey water tank 138 through the first grey water output pipe 153 for storage in preparation for grey water reuse.

[0165] Example 11;

[0166] On the basis of Examples 1 to 8 and 10, Figure 1 、 Figure 12 As shown, when the gray water accumulates to a certain level, triggering the sixth full level sensor 141 on the gray water tank 138, the gray water pump 166 begins to operate, pumping the gray water in the gray water tank 138 through the first gray water outlet 142, the second gray water output pipe 167, the gray water pump 166, and the gray water inlet pipe 165 into the clean water tank 157 for flushing. When the gray water level in the gray water tank 138 drops to the point where the fifth low level sensor 143 is triggered, or when the water level in the clean water tank 157 rises, triggering the seventh full level sensor 158 of the clean water tank, the gray water pump 166 stops operating.

[0167] When the system is used for the first time or is used again after being out of use for a period of time, the clean water tank 157 must first be filled with clean water from a surface water source.

[0168] Example 12:

[0169] On the basis of Examples 1 to 8 and 10, Figure 1 、 Figure 13As shown: the odor from the aforementioned solid-liquid separation subsystem and microwave incineration subsystem and the high-temperature steam and flue gas that have not been completely liquefied produced by the electrodeless photocatalytic treatment urine subsystem after heat exchange are sent into the electrodeless photocatalytic treatment waste gas treatment device 105 through the axial flow fan 102, the waste gas inlet pipe 103, and the waste gas inlet port 104, and are deodorized and degraded by organic gases through photochemical reactions and then discharged from the clean gas outlet 106.

[0170] Example 13;

[0171] like Figure 1 、 Figure 14 As shown, when the system is first used or restarted after a period of inactivity, fresh water tank 157 must first be filled with fresh water from a surface water source. The filling path is: fresh water connector 164, fresh water inlet 162, and fresh water tank 157. Fresh water connector 164 uses a fire hose connector specifically designed for fire protection systems, allowing fresh water to be directly introduced through the fire hose interface.
