Description

Technical Field

[0001] The present invention relates to an emission reduction system, process, equipment and toilet standard, which is applicable to green buildings and urban renewal scenarios. Background Art

[0002] High-rise buildings and the urbanization process have led to the deterioration of the ecological environment. At the bottom of the drainage vent pipe inside high-rise buildings, biogas methane, adsorbed organic matter and pathogenic microorganisms are generated in the anaerobic environment of the sewage pipe network and are discharged into the airspace above the roof of high-rise buildings through the chimney effect of the roof vent pipe. At the same time, the existing drainage system divides domestic wastewater into domestic sewage and domestic wastewater, and promotes a building drainage system and end-treatment process with separate sewage and wastewater and combined urination. As the starting point of the drainage system and the source of end-treatment, the "Sanitary Appliance Installation Standard" promotes a single urinal combined device as follows: As a result, urine sewage accounting for 1% of the drainage volume contributes 80% of the nitrogen source and 50% of the phosphorus source through the sanitary appliance installation standard and the separate sewage and wastewater drainage system, exceeding the carbon-nitrogen-phosphorus ratio of the end-treatment process and overflowing and discharging, resulting in eutrophication pollution of the receiving water body. In addition, the externally added carbon source for denitrification and the doubled carbon emissions of the internal reflux are transferred to the atmospheric environment, promoting drastic climate change and forming the long-tail effect of end-treatment. Summary of the Invention

[0003] Therefore, the task of the present invention is to design an emission reduction system, process, equipment and toilet standard to solve the inherent water and gas pollution problems of the existing drainage system, end-treatment process and "Sanitary Appliance Installation Standard", namely "combined urination at the source, energy-consuming treatment at the end, carbon source transferred to the atmosphere, and nitrogen and phosphorus polluting the water body".

[0004] The emission reduction system of the present invention is realized as follows. Under the technical background where the drainage system is already in place and the signs of climate change are emerging, the domestic sewage or drainage equipment is classified and characterized according to homogeneous (carbon sink type) and heterogeneous (carbon source type), and a homogeneous-non-separated negative carbon emission reduction system is constructed. Among them, homogeneous sewage represents urine sewage, heterogeneous sewage represents flushing sewage, homogeneous wastewater represents body cleaning, showering and / or washing wastewater, and heterogeneous wastewater represents kitchen, floor drain (laundry) and / or other wastewater. The homogeneous sewage and homogeneous wastewater are combined in the same phase and separated in different phases with heterogeneous sewage and heterogeneous wastewater. The homogeneous-non-separated process equipment is used for carbon removal and solid removal or nitrogen and phosphorus removal to obtain low-carbon high-nitrogen homogeneous drainage and high-carbon low-nitrogen heterogeneous drainage. The low-carbon high-nitrogen homogeneous drainage is specifically supplied to the fertilizer-water integrated carbon sink system, such as facility agriculture, carbon sink gardens, plant factories or rooftop gardens, to utilize nitrogen and phosphorus for carbon fixation and carbon sink enhancement, and develop new agents; the high-carbon low-nitrogen heterogeneous drainage is transported to the sewage treatment plant along the old system for energy conservation and emission reduction, and develop nitrification liquid or regenerate new energy, achieving unexpected negative carbon emission reduction effects. Compared with the sewage-wastewater separated drainage system, the homogeneous-non-separated emission reduction system utilizes nitrogen and phosphorus for carbon fixation and carbon sink enhancement, develops new agents, conserves energy and reduces emissions, and regenerates new energy, having outstanding substantial features and remarkable progress.

[0005] The emission reduction process of the present invention is realized as follows. The homogeneous sewage and homogeneous wastewater are combined in the same phase and separated in different phases with heterogeneous sewage and heterogeneous wastewater. The homogeneous-non-separated process equipment is used for carbon removal and solid removal or nitrogen and phosphorus removal to obtain low-carbon high-nitrogen homogeneous drainage and high-carbon low-nitrogen heterogeneous drainage. The low-carbon high-nitrogen homogeneous drainage is specifically supplied to the fertilizer-water integrated carbon sink system, such as facility agriculture, carbon sink gardens, plant factories or rooftop gardens, to utilize nitrogen and phosphorus for carbon fixation and carbon sink enhancement. The residual nitrogen and phosphorus redundant effluent is nitrified and oxygenated to prepare deodorant agents, or municipal nitrification liquid is introduced from the sewage treatment plant to flush (low floors of high-rise buildings) toilets with medicine to control haze. The nitrification liquid is used to finely adjust the anaerobic environment of the sewage by controlling the release of oxygen, and inhibit the methane and chimney effect of the sewage vent pipe. The flushing sewage and heterogeneous wastewater are transported to the sewage treatment plant along the old system for energy conservation and emission reduction, and develop nitrification liquid or regenerate new energy, achieving unexpected negative carbon emission reduction effects. Compared with the end-treatment process, the homogeneous-non-separated negative carbon process utilizes nitrogen and phosphorus for carbon fixation and carbon sink enhancement or develops new agents, conserves energy and reduces emissions, and regenerates new energy, having outstanding substantial features and remarkable progress.

[0006] The process equipment of the present invention is realized as follows: Classify and characterize drainage equipment according to homogeneous (carbon sink type) and heterogeneous (carbon source type), construct a homogeneous and non-diverting twin toilet with a water-saving toilet as the prototype. Among them, configure the original toilet with the sign of "for defecation only, not suitable for urination" to form a heterogeneous (carbon source) defecation toilet, configure the prototype toilet with the sign of "for urination only, defecation prohibited" to form a homogeneous (carbon sink) urinal, reduce the waterway diameter of the sewage outlet of the prototype toilet to form the water collection port of the homogeneous (carbon sink) urinal, set a fine grille at the water collection port of the urinal to form a facility to prevent misusing for defecation, retain the squatting and sitting pans of the prototype toilet above the fine grille to form a gender-neutral homogeneous (carbon sink) urinal, embed the homogeneous (carbon sink) urinal in a public toilet or bathroom to capture nitrogen and phosphorus and obtain low-carbon and high-nitrogen homogeneous drainage, and retain the heterogeneous (carbon source) defecation toilet in the public toilet or bathroom to capture carbon and obtain high-carbon and low-nitrogen heterogeneous drainage. Replace the flush tank supporting the prototype toilet with a bidet, a washbasin or a basin cover tank to form an integrated (lavatory) urinal, use the wastewater from bidet or handwashing to flush the urine sewage to obtain low-carbon and high-nitrogen homogeneous drainage, or replace the flush tank supporting the prototype toilet with a shower, combine it with the shower up and down and intensively set it under the shower to form an integrated (shower) urinal, use the water collection tray (equipped with a coarse grille flap) of the urinal to receive shower wastewater to expand the homogeneous drainage, and achieve unexpected water-saving and emission-reduction effects. Forcefully match it with the heterogeneous (carbon source) defecation toilet and couple it in female toilets and bathrooms to fill the gap of urinals and achieve water-saving and emission-reduction effects.

[0007] The process equipment of the present invention can also be realized as follows: Expand the flush tank supporting the original toilet into a deodorizing, haze-control and dosing equipment, use nitrification liquid to flush the toilet, utilize controlled-release oxygen to fine-tune the anaerobic environment of sewage, inhibit the methane and chimney effect of the vent pipe of sewage, and reduce the emission of non-carbon dioxide greenhouse gases. Or add a dosing port and a dosing pipe to the original toilet body, and support other (haze-control and dosing) equipment and the drain pipe of appliances. Connect the dosing pipe of the defecation toilet to the drain pipe of the appliance and set a bottom valve together to form a "flat and plug combination" heterogeneous drainage equipment. Usually, keep the bottom valve closed and add medicine from the dosing port of the defecation toilet. When the defecation toilet is blocked, open the bottom valve to drain the overflow liquid of the defecation toilet emergently. After dredging, restore the state of keeping the bottom valve closed and adding medicine, and achieve unexpected haze-control and anti-blocking effects.

[0008] The setting standards of the present invention are realized as follows: The homogeneous (carbon sink) urinals are compulsorily matched and coupled with the heterogeneous (carbon source) toilets and set in, including but not limited to, women's toilets and restrooms, filling the gap of urinals. The homogeneous and non-diverting twin toilets are written into the "Setting Standards for Sanitary Appliances" of public buildings or residential buildings to replace the original toilets. The homogeneous and non-diverting twin toilets are used in combination with other sanitary appliances to form the minimum necessary standards for women's toilets (a set of three) or restrooms (a set of four), alleviating the shortage of toilet positions during holidays. The homogeneous (carbon sink) urinals are integrated with bidets, wash basins or basin cover water tanks as flushing devices, and are compulsorily embedded and intensively set in, including but not limited to, women's toilets or restrooms, using the waste water from bidets or handwashing to flush the urine sewage. The homogeneous (carbon sink) urinals (with coarse grid flaps installed on their squatting or sitting pans) are combined with showers vertically and three-dimensionally set in, including but not limited to, restrooms, increasing the shower waste water to expand the reclaimed water for flushing toilets, achieving unexpected water-saving, emission-reduction and land-saving effects. Compared with the current setting standards for sanitary appliances or the women's toilets (a set of two) and restrooms (a set of three), it has outstanding substantive features and remarkable progress.

[0009] By classifying and characterizing domestic wastewater or drainage equipment into homogeneous (carbon sink type) and heterogeneous (carbon source type), constructing a homogeneous and non-diverting emission reduction system to remove carbon and solids or remove nitrogen and phosphorus, obtaining low-carbon and high-nitrogen homogeneous wastewater and high-carbon and low-nitrogen heterogeneous wastewater. The low-carbon and high-nitrogen homogeneous wastewater is specially supplied to the carbon sink system of integrated fertilizer and water utilization to utilize nitrogen and phosphorus for carbon fixation and carbon sequestration or develop new agents; the high-carbon and low-nitrogen heterogeneous wastewater is transported to the sewage treatment plant along the old system for energy conservation and emission reduction, developing nitrification liquid or regenerating new energy, achieving unexpected negative carbon emission reduction effects. Compared with the sewage and waste water diversion drainage system, it has outstanding substantive features and remarkable progress. Description of the Drawings

Detailed implementation manners

[0016] [Example 1] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 Upgrade the "Hygienic Appliance Installation Standard" from a single toilet combined setting to a twin toilet split setting, constituting examples such as concentrating and differentiating domestic sewage in female toilet bathrooms, negative carbon emission reduction, cultivating facility agriculture and carbon sink plants.

[0017] Specifically, squat and sitting toilets are used as prototypes to construct non-diverting twin toilets. For the original toilet, add the label "For defecation only, not suitable for urination" 3 to form a heterogeneous (carbon source) toilet 1. Convey the high-carbon and low-nitrogen heterogeneous drainage 23 along the old system to the sewage treatment plant for energy conservation, emission reduction, development of nitrification liquid or renewable new energy. Add the label "For urination only, defecation prohibited" 4 to the prototype toilet to form the prototype of a homogeneous (carbon sink) urinal 2. Narrow the waterway diameter of the sewage outlet 5 of the prototype toilet (add a fine grille) to form the fine grille water inlet (anti-defecation water inlet) 6 of the homogeneous (carbon sink) urinal 2. A separate drainage system is installed below the fine grille water inlet 6, and the low-carbon and high-nitrogen homogeneous drainage 18 of the homogeneous (carbon sink) urinal 2 is separately recovered through the raw water interface 19-2 of the diversion pipe gallery 19. The upper part of the fine grille water inlet 6 retains the squat and sitting shapes of the prototype toilet to form a gender-neutral squat and sitting urinal, that is, the main body of the homogeneous (carbon sink) urinal 2. Replace the flushing water tank 7 supporting the prototype toilet with a washbasin or a basin cover water tank 8, and fill the blank of the urinal (two-piece set) in the women's toilet in the standard toilet occasion. After the user urinates, tap water 16 from the new water interface 19-1 of the diversion pipe gallery 19 is used for handwashing on the spot, and the handwashing wastewater is used to enhance the flushing of urine sewage to form a "low-carbon and high-nitrogen" homogeneous drainage 18, achieving the treatment effect of reducing water volume and decarbonizing and removing solids. The low-carbon and high-nitrogen homogeneous drainage 18 is recovered to the pre-treatment for harmless treatment and then incorporated into the "integrated water and fertilizer" irrigation intermediate water 20, which is connected to the intermediate water interface 19-3 of the diversion pipe gallery 19 for facility agriculture or plant factories to cultivate carbon sink plants 21, achieving the purpose of ecological treatment of denitrification and phosphorus removal and negative carbon emission reduction. For high-grade homogeneous (carbon sink) urinals, replace the flushing water tank 7 supporting the prototype toilet with a bidet 10, which is convenient for the user to clean themselves in place after urinating and use the bidet wastewater to flush urine sewage to form or amplify the "low-carbon and high-nitrogen" homogeneous drainage 18. The irrigation facility agriculture or plant factory absorbs nitrogen and phosphorus through the carbon sink plant 21 and then nitrifies and oxygenates it into the intermediate water 22 for haze control and toilet flushing, and is connected in series through the intermediate water interface 19-3 to supplement the flushing water tank 7 supporting the heterogeneous (carbon source) toilet 1. Or an overflow port or a dosing pipe 13 is provided on the original toilet body, and other (haze control dosing) equipment 11 and an overflow valve 17 for the appliance drain pipe are supporting. Connect the overflow port or the dosing pipe 13 to the overflow valve 17 of the appliance drain pipe to form a "flat plug combination" heterogeneous drainage device. Usually, the overflow valve 17 of the appliance drain pipe is kept closed, and the toilet drains or doses in a combined manner from the toilet body. When the toilet is blocked, the overflow valve 17 of the appliance drain pipe is opened for emergency drainage, and the overflow liquid of the toilet is bypassed and drained to the side, and medicine is directly added to the heterogeneous drain pipe. After the toilet is unclogged, the overflow valve 17 of the appliance drain pipe is closed to restore the combined drainage or dosing state of the body, achieving an unexpected effect of haze control and anti-blocking.The flushing sewage follows the indoor drainage system and converges with the heterogeneous wastewater to form "high-carbon and low-nitrogen" heterogeneous drainage. 23 It is then transported through the outdoor drainage system pipeline for denitrification or sent to the sewage treatment plant to develop new agents, save energy and reduce emissions, and regenerate new energy, reducing the nitrogen and phosphorus removal load of the sewage treatment plant, reducing the three-stage treatment process and three times the recirculating aeration water volume, reducing the eutrophication pollution of the receiving water body and carbon dioxide transfer emissions, and achieving unexpected negative carbon emission reduction effects. Compared with the existing "Sanitary Appliance Setting Standards" and the separate drainage system for sewage and waste water, the adoption of the non-separate emission reduction system to consume nitrogen and phosphorus, sequester carbon and increase sinks, develop new agents, save energy and reduce emissions, and regenerate new energy has prominent substantial features and significant progress.

[0018] [Example 2] Refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 Upgrade the "Sanitary Appliance Setting Standards" from a single toilet confluence setting to a twin toilet separate setting, forming examples such as concentrating and differentiating domestic sewage in residential bathrooms, reducing carbon emissions, cultivating facility agriculture, and carbon sink plants.

[0019] Specifically, a shower 12, a bidet 10, a coarse grille / water collector 14, and a homogeneous (carbon sink) urinal 2 are vertically arranged according to ergonomics from top to bottom. Their vertical matching and three-dimensional combination form an integrated (shower) urinal 24. In this way, the source treatment decarbonization and solid removal equipment are integrated into the integrated (shower) urinal and intensively set in the residential bathroom. Usually, the homogeneous (carbon sink) urinal 2 and the bidet 10 are used. During showering, the homogeneous (carbon sink) urinal 2 and the coarse grille water collector 14 are used as the water collection pedal or seat for the shower 12. When taking a bath, the urinal cover is closed, and the turbid water from taking a bath is discharged through the floor drain 15. When showering and cleaning, the urinal cover is opened, and hair is intercepted from the coarse grille water collector 14 and the fine grille water inlet 6 for organized recovery of shower wastewater, forming or amplifying "low-carbon and high-nitrogen" homogeneous drainage 18. It is incorporated into the "integrated water and fertilizer" irrigation middle water 20 to irrigate facility agriculture or plant factories. After ecological treatment of nitrogen and phosphorus removal by carbon sink plants 21, the redundant irrigation middle water 20 and residual nitrogen and phosphorus nutrients are nitrified and oxygenated and connected in series through the middle water interface 19-3 to the flushing water tank 7 supporting the twin toilets 1 to supplement the flushing middle water 22. Among them, a sign 9 of "flushing middle water, do not touch" is configured outside the flushing water tank 7. The flushing middle water 22 adopts a complete or semi-complete separate flow system of "raw water non-separate flow, middle water nitrogen and oxygen dedicated supply" to substitute for sewage reoxygenation, floor drain deodorization, virus aerosol removal from the vent pipe, methane removal from the pipe network, or denitrification nitrogen removal in the pipeline, achieving unexpected disease removal and emission reduction effects. Compared with the current sewage and waste water drainage system and end treatment process, the present invention can improve the resource utilization, harmlessness, reduction, and synergistic efficiency of sewage, reduce the nitrogen removal load and carbon emissions of the end sewage treatment plant, and reduce the eutrophication pollution of the receiving water body, having prominent substantial features and significant progress.
