Background

The problem of environmental discharge of passenger excreta is one of the major problems troubling the passenger transport field and one of the major technical problems to be broken through in the world so far. From the current application situation, the closed toilet type adopted in the passenger transport field of either highway passenger transport or railway passenger transport, or airplanes, ships and the like mainly comprises a vacuum holding type excrement collector, a compact type vacuum excrement collector, a circulating type excrement collector, a pressure flushing type excrement collector and the like. These closed toilets currently only have the function of collecting the excrement, and do not perform any treatment during the movement of the vehicle, but evacuate the sewage in the excrement collection tank at the fixed station, the passenger station, the vehicle section, the airport, the passenger wharf, etc. through a special sewage dump truck or a fixed evacuation device matched with the ground, and the sewage is either directly delivered to a municipal sewage treatment plant by the sewage dump truck or simply treated by a local septic tank or an anaerobic tank and then discharged into a municipal sewage pipe network.

The sewage of the toilet wastewater for long-distance passenger transport has high organic matter concentration, ammonia nitrogen concentration and suspended matter concentration, so the treatment difficulty is high. According to the national environmental protection requirement, the water discharged into the municipal pipe network meets CJ 343-2010 quality standard for sewage discharged into town sewers, and if the water is required to meet the requirement, a dilution method is adopted in addition to the corresponding biological treatment method, so that the required water quantity is larger. In addition, urban sewage treatment facilities in China are not developed completely, corresponding urban pipe networks do not exist around a plurality of vehicle sections and passenger storage facilities, the urban pipe networks are required to be discharged into the urban pipe networks, the required pipe network investment is high, and the quantity of storable fecal sewage is limited. The sewage is delivered to a municipal sewage treatment plant by adopting the sewage discharge truck, and the working capacity can not meet the requirement of the existing passenger transport.

In addition, including but not limited to aviation toilets, vehicle-mounted trailer-type portable toilets, and ground-mounted eco-friendly toilets, all have the following commonalities:

1. most of human excrement is only collected, and excrement, urine and the like are not treated, so that the standard emission is not mentioned, and the method is basically indistinguishable from a traditional toilet and cannot realize zero-pollution standard emission;

2. most of excrement is not subjected to solid-liquid separation treatment, and excrement liquid coexists, so that the subsequent treatment difficulty is high;

3. the sewage tank/excrement storage tank has limited capacity, when the sewage tank/excrement storage tank is full of sewage, sewage discharge treatment must be carried out, otherwise, the toilet must be stopped, and site environment pollution and inconvenience in use are caused;

4. a large amount of odor is discharged in the processes of suction, pollution discharge and transportation of the sewage discharge truck, and the bad influence is generated on the environment, so that the problems of local pollution and safety risk still exist;

5. the sewage collected by the excrement collector is subjected to ground centralized treatment, a large amount of ground water is required to be diluted, the cost is high, and huge manpower, financial resources and material resources are required to be consumed;

6. the sewage discharge needs special equipment, the labor and equipment investment cost is high, the maintenance workload is large, in addition, the excrement and urine treatment occupies social resources, and the urban sewage and sewage treatment pressure is increased;

in view of the above, the market does not provide a complete toilet technical solution with movable net discharge and without sewer to meet the development requirement in the technical field of passenger transportation, and therefore, a need exists for developing and innovative design on the basis of the solution.

when the toilet bowl 1 is filled with feces, the toilet bowl full level switch 4 outputs a toilet bowl flushing command, and the execution process of the command is consistent with the toilet bowl flushing command sent by the flushing button 173.

Example 2:

in addition to example 1, as shown in fig. 1 and 3: the main body of the dirt collecting box 9 is cylindrical and can bear certain negative pressure and positive pressure repeatedly.

Example 3:

in addition to examples 1 and 2, as shown in fig. 1 and 4: the solid-liquid separation box 20 is divided into 3 inner cavities: solid substance cavity, liquid cavity, supernatant liquid cavity.

the lower part of the slide filter plate 25 is stored with a certain amount of black water for ensuring proper fluidity of the solid matter.

Example 4:

on the basis of embodiments 1 to 3, as shown in fig. 1 and 5: the sewage pump with reamer 40 will cut up the solid and deposition from the solid-liquid separation subsystem, and send it into the coarse pulp tank 49 through the first coarse pulp delivery pipe 46, when there is some coarse pulp in the coarse pulp tank 49, the first low level sensor 52 will be activated, and the coarse pulp will flow into the electric crusher 54 through the second coarse pulp delivery pipe 53 and start to work.

Example 5:

on the basis of embodiments 1 to 4, as shown in fig. 1 and 6: the fine pulp crushed and ground by the electric crusher 54 directly falls into the fine pulp tank 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.

Example 6:

in addition to embodiments 1 to 5, as shown in fig. 1 and 7: the fine pulp sucked from the fine pulp tank 56 by the first self-priming pump 61 is sent into the fine pulp preheating tank 63 through the second fine pulp conveying pipe 62 and the fine pulp inlet 67, and the temperature control sensor 68 is used for detecting the temperature of the fine pulp and controlling the work of the annular heater 69 through an intelligent control system.

Example 7:

based on embodiments 1 to 6, as shown in fig. 1 and 8: the fine slurry preheated by the fine slurry preheating box 63 is pressurized by the second self-sucking pump 85 and then sent to the atomizing nozzle of the microwave incinerator 71 to be atomized and dried in the microwave incinerator and incinerated in the incineration area, and the incinerated ash residues are temporarily stored above the ash residue discharge port 72 and cleaned and discharged when the ash residues are discharged in a condition.

The air-water control device 177 feeds fresh air with certain pressure into the microwave incinerator 71 through the compressed air delivery pipe 78, the first tee joint 79, the microwave incinerator air inlet pipe 80 and the first compressed air inlet 73, so that on one hand, the fresh air is used for supporting combustion, and on the other hand, solid matters dried in a drying area of the microwave incinerator can be stirred to be fully combusted. The compressed air blows high-temperature hot steam generated in the microwave incinerator 71 and high-temperature exhaust gas after combustion into the slurry preheating tank 63 through the flue gas inlet pipe 70 to preheat the slurry.

Example 8:

in addition to embodiments 1 to 3, as shown in fig. 1 and 9: when the feces evacuation valve 18 is closed for a certain time, the electrodeless photocatalytic treatment urine treatment device is started to preheat, the electromagnetic valve 115 for conveying the supernatant liquid pipe in the solid-liquid separation device is opened, the first electric booster pump 117 of the heat exchange subsystem works, and the pressurized supernatant liquid with a certain pressure is conveyed to the atomizing nozzle 135 of the electrodeless photocatalytic treatment urine treatment device through the heat exchanger 147, the high-temperature supernatant liquid input pipe 119 and the supernatant liquid input port 134 to be subjected to microwave electrodeless photocatalytic degradation sterilization treatment.

During the degradation treatment process of the supernatant, a large amount of high-temperature steam (containing a certain amount of odor, the same below) is generated, the steam sends the pressure air sent by the air source system and the high-temperature flue gas generated by the microwave incineration system into the heat exchange system to heat the supernatant input system, and the conveying paths of the high-temperature steam are as follows in sequence: the electrodeless photocatalytic treatment urine processing device 132, the high-temperature steam outlet 133, the third tee 108, the high-temperature gas conveying pipe 109 and the heat exchanger 147.

The air-water control device 177 sends fresh air with certain pressure to the urine treatment device 132 through the compressed air delivery pipe 78, the first tee joint 79, the compressed air input pipe 81 and the second compressed air input port 137, so that on one hand, liquid sprayed out from an atomizing nozzle of the urine treatment device 132 subjected to the electrodeless photocatalytic treatment can be stirred to be fully degraded, on the other hand, the degraded high-temperature water vapor is promoted to be discharged, and the circulation of the water vapor is facilitated.

Because the supernatant is not fully preheated in the starting process of the urine treatment device by the electrodeless photocatalytic treatment and the microwave incineration system, part of atomized water still falls to a liquid collecting area at the lower part of the urine treatment device by the electrodeless photocatalytic treatment in the form of the supernatant, and is sent back to the residual liquid tank 124 through the waste liquid discharge port 136 and the waste liquid discharge pipe 120 of the urine treatment device 132 by the electrodeless photocatalytic treatment and finally returns to a supernatant cavity of the solid-liquid separation system.

Example 9:

in addition to embodiments 1 to 3 and 8, as shown in fig. 1 and 10: the raffinate tank 120 collects and stores:

the supernatant fluid overflowed by the solid-liquid separation system has the following path: the solid-liquid separation tank 20, the sewage overflow outlet 29, the sewage overflow pipe 111 and the overflow liquid discharge inlet 127 of the solid-liquid separation subsystem are discharged into the residual liquid tank 120 for temporary storage.

Part of atomized water of the urine treatment device for electrodeless photocatalytic treatment falls to a liquid collecting area at the lower part of the urine treatment device for electrodeless photocatalytic treatment in the form of supernatant, and is sent back to the residual liquid tank 124 through a waste liquid outlet 136, a waste liquid discharge pipe 120 and an untreated supernatant discharge inlet 128 of the urine treatment device for electrodeless photocatalytic treatment 132.

Example 10:

in addition to embodiments 1 to 8, as shown in fig. 1 and 11: after the microwave incinerator 71 works, high-temperature hot steam generated after solid material incineration and high-temperature waste gas after combustion preheat fine slurry through a flue 76 in a fine slurry preheating box 63, are mixed with a high-temperature hot steam output pipe 110 discharged by an electrodeless photocatalytic treatment urine subsystem through a flue port 77 and a flue gas discharge pipe 107 through a third tee 108, are sent to a heat exchanger 147 through a high-temperature flue gas input pipe 109 and a high-temperature flue gas inlet 149 to carry out heat exchange on black water sent to the electrodeless photocatalytic treatment urine subsystem, are mixed with odor through a flue gas outlet 148, a flue gas output pipe 101 and a second odor pipeline tee 156, are sent to the electrodeless photocatalytic treatment waste gas treatment subsystem through an axial flow fan 102 to carry out odor removal and degradation treatment on organic gas, and are discharged from a clean gas discharge port 106.

High-temperature hot steam generated by the microwave incinerator, high-temperature waste gas after combustion and high-temperature hot steam discharged by the electrodeless photocatalytic treatment urine subsystem exchange heat with normal-temperature supernatant liquid output by the solid-liquid separation box 20 in the heat exchanger 147, moisture in the high-temperature hot steam is condensed and washed out to generate reclaimed water, the reclaimed water falls into a hopper-shaped reclaimed water storage area at the lower part of the heat exchanger, and the reclaimed water falls into a reclaimed water tank 138 through a first reclaimed water output pipe 153 to be stored for preparing for reclaimed water reuse.

Example 11;

in addition to embodiments 1 to 8 and 10, as shown in fig. 1 and 12: when the reclaimed water is collected to a certain degree, the sixth full level sensor 141 on the reclaimed water tank 138 is actuated, the reclaimed water pump 166 starts to work, and the reclaimed water in the reclaimed water tank 138 is pumped into the clean water tank 157 through the first reclaimed water outlet 142, the second reclaimed water outlet pipe 167, the reclaimed water pump 166 and the reclaimed water inlet pipe 165 for flushing the toilet. When the water level of the reclaimed water in the reclaimed water tank 138 is lowered to the action of the fifth low level sensor 143 or the water level in the clear water tank 157 is raised to trigger the seventh full level sensor 158 of the clear water tank, the reclaimed water pump 166 stops working.

When the system is first applied or is to be reused after a period of inactivity, the clear water tank 157 is first filled with clear water from the surface water source.

Example 12:

in addition to embodiments 1 to 8 and 10, as shown in fig. 1 and 13: the odor of the solid-liquid separation subsystem and the microwave incineration subsystem and the high-temperature steam and the smoke which are generated by the heat-exchanged electrodeless photocatalytic treatment urine subsystem and are not completely liquefied are sent to an electrodeless photocatalytic treatment waste gas treatment device 105 through an axial flow fan 102, a waste gas input pipe 103 and a waste gas input port 104, are subjected to photochemical reaction to carry out deodorization and degradation treatment on organic gas, and are discharged from a clean gas discharge port 106.

Example 13;

as shown in fig. 1 and 14: when the system is first applied or is to be reused after a period of inactivity, the clear water tank 157 is first filled with clear water from the surface water source. The water filling path is as follows: clean water joint 164, clean water inlet 162, clean water tank 157. The clean water joint 164 is a fire-fighting pipe joint special for a fire-fighting system, and clean water can be directly introduced through a fire-fighting pipeline interface.
