Description

Eco-Friendly Toilets with Water-Free, Water-Free Circulation Flushing

The present invention relates to an environment-friendly unpaid water, non-discharge circulation flush manure and sewage treatment apparatus that can be recycled by highly purified manure and sewage discharged from the flush toilet, more specifically to the manure and sewage generated in the flush toilet. Unrefined, no-release circulation flush that can completely recycle the treated water to the flushing toilet after thoroughly purifying the organic suspended solids and eutrophication agents included nitrogen, phosphorus, color, odor, harmful ingredients and harmful pathogens. The present invention relates to an environment-friendly toilet advanced processing apparatus.

Generally, public toilets installed in mountain huts, temples, hiking trails, riversides, beaches, trails, or other campsites without water and sewage pipes have problems with toilet water supply, odor, water quality, and environmental pollution. As a result, there has been an active supply of non-discharge circulation flush toilets with the ability to purify. However, many toilets are naturally fermented and bubble-type toilets. Avoid using toilets, and manure from public toilets is either uncleaned or flooded, seriously contaminating the water quality of rivers and valleys.

The problem described above is similar in the case of a septic tank flush toilet equipped with a water and sewage pipeline, which not only acts as a secondary pollutant that worsens the quality of sewage as the manure and the treated water are discharged to the sewage pipe. Odor generated from the gas and backflow of various gases, but recently recognized as a cultural space has become a fatal problem in creating a comfortable toilet environment, and also has a lot of difficulties in the maintenance of the toilet.

In particular, in the case of flush toilets, in order to solve the problems as described above, in the toilets under the condition where the water and sewage pipeline is not provided, the discharged manure and manure that can be recycled by itself without being discharged to the outside can be recycled. And sewage treatment facilities have been actively proposed, but the existing non-discharge circulation flush toilet has a sewage treatment facility installed in a limited space due to excessive operation load and unstable treatment system compared to the capacity of the sewage treatment facility and an error in the treatment system. As normal operation is difficult or the manure and sewage treated in each treatment tank is insufficient and unstable, the manure and sewage can be circulated while the final treated water is stored by circulating the sewage treatment facility without sufficient purification. Easy, severe in treated water Take it, or if the problem still remains that the color gray water exceeds water quality standards, including clear and not transparent offensive has to be realistic recycling process difficult.

Generally, water quality is divided into constant, heavy water, and sewage. Constant water refers to drinking water quality, and heavy water is water quality that can be used for planting water, agricultural water, plant cooling water, equipment washing water, or toilet bowl cleaning, although drinking is difficult. Refers to the quality of water discharged after use in everyday life. Of course, each type of water quality has a more rigorous use range and water quality range, but detailed descriptions are omitted.

However, related organizations such as K-water strongly recommend the use of heavy water as well as drinking water constants for water quality management, water resource protection and efficient use.

As such, the water quality of heavy water prescribed in the relevant regulations cannot be used as heavy water because odors or odors occur in the water, turbidity of color, or transparency decreases.

Currently, the water quality of heavy water recycled by self-purification in recycled public toilet without discharge should completely remove color and odor as well as organic matter and nitrogen phosphorus, but natural wood media such as wood chips used as a filter in the process of manure and sewage If the natural lignin pigment component eluted from is not completely removed due to the lack of removal technology or the organic matter, nitrogen and phosphorus are not sufficiently purified, the natural lignin pigment component is supplied to the toilet water and is supplied to the toilet water. In addition to the dark red color in addition to corrupt and severe odors to avoid the use of the toilet in fact to stop the operation of the toilet or to close the public toilet at all.

In the treatment of manure and sewage discharged from public toilets, technology to remove bad odors, technology to purify unclean sewage color to clear and clear water level, sterilization technology to remove harmful pathogens, and eutrophication agents included in sewage Nitrogen, phosphorus and perishable organics removal technologies must be solved comprehensively, but the sewage treatment devices applied to the public toilets currently installed do not completely solve the above-mentioned problems.

For example, the existing zero-flow circulation flush toilet, which is installed and operated, is initially treated to a level where the water quality of the treated water reaches a heavy water standard, but as the repetitive circulation continues, the water quality of the treated water is colored, odorous, organic suspended solids, etc. Because of the extremely poor problem occurs due to the accumulation of a lot of problems in the operation of the toilet, such as frequently replacing the treated water or media in the reaction tank (water tank) or supplying clear water from the outside to lower the pollution concentration of water quality. Due to these reasons, the discharge-free flush toilet sewage treatment system and facilities are far short of remarkable levels.

The inventors of the present invention reliably and innovatively treat the manure and sewage discharged from public toilets through years of research and development, pilot experiments, pilot site installation operation and verification to improve the comfortable and sanitary toilet environment and sewage treatment efficiency. In order to improve efficiency and to complete the sewage treatment technology that can highly treat the water quality of the recycled final treated water as colorless, odorless, and sterile clear water, the present invention has been researched and developed for many years by the present inventors. And a sewage treatment apparatus.

It is an object of the present invention that the water supply does not need any more water than the water filled in each treatment tank when the sewage treatment apparatus is operated, and does not discharge into sewers or streams by recycling the final treated water to the toilet water (no discharge). It prevents pollution of sewage or river water, and eliminates and eliminates organic suspended solids (organic substances) by itself, eliminating the need for separate collection of manure (no collection), and removing odors and filthy sewage from manure and sewage. It is to provide a fixed or mobile eco-friendly toilet equipped with an unpaid water free circulating flush advanced treatment device that can be completely removed and recycled to the level of heavy water (colorless odorless).

Another object of the present invention is to solve the problems of the bad smell, dirty color, etc. generated by circulating the treated water that is not properly treated due to the instability of the existing system, the existing discharge-free circulation flush toilet system perfectly to the clear water level It is intended to achieve a stable practical use of a zero discharge circulation flush toilet that can be recycled into the flushing water of a flush toilet by the highly purified treatment.

Hereinafter, described in detail with reference to the accompanying drawings for the water-free water, non-discharge circulation flush type eco-friendly toilet advanced processing apparatus according to the present invention.

1 and 2, Figure 1 is a layout diagram of the reaction tank (water tank) illustrating the adoption of a water-free, discharge-free circulation flush type eco-friendly toilet advanced treatment apparatus according to the present invention in a fixed toilet.

The fixed toilet is a fixed toilet building where concrete is cured on the ground, a toilet is installed on the ground, and an altitude treatment device is installed in the basement under the toilet.

As shown in Figure 1, the water-free, non-discharge circulation flush eco-friendly toilet advanced processing apparatus 100 according to the present invention applied to the fixed toilet (1a), toilet flush (1b), anaerobic storage tank (10), aerobic biological reaction tank (20), flow rate adjustment tank 30, organic material extinction reaction tank 40, advanced treatment tank 50, bioreaction tank 70, depigmentation filtration tank (80), treatment water storage tank (90) and toilet toilet (1b) Manure and sewage discharged from the) passes through the above reaction tanks in order to remove organic matter, nitrogen, phosphorus and odor, and at the same time to discolor the color of the water transparently sterilize harmful pathogens and then treated water storage tank (90) Store in The treated water stored in the treated water storage tank 90 is timely supplied to the toilet flush 1b and recycled into the toilet washing water. The present invention purifies the manure and sewage while repeatedly performing the above treatment process and recycles the treated water.

Referring to Figure 2, Figure 2 is an enlarged view of the storage tank showing the detailed configuration of the storage tank shown in Figure 1, anaerobic storage tank 10 is a flush toilet as a tank for storing the manure and sewage discharged from the toilet inlet ( Manure and sewage discharged in 1b) are decomposed by anaerobic digestion in an anaerobic state. Anaerobic digestion means that anaerobic bacteria or microorganisms use oxygen in organic compounds and oxygen in compounds such as nitrites, nitrates, and sulfates to decompose organic matter in the anaerobic state, and generate methane gas, carbon dioxide, and hydrogen sulfide as by-products. Through anaerobic digestion, the sludge becomes stable and easy to treat, reducing its capacity.

The anaerobic storage tank 10 is filled with a certain amount of water, and mineral media and plastic media or natural mineral media such as oyster shells and porous volcanic stones (not shown) are required to increase the activity of anaerobic microorganisms in water. A certain amount is filled, and the water level sensor 11 is attached to a predetermined position of the tank in order to discharge a predetermined amount of flow in response to the inflow amount of manure, and a cutter capable of cutting and grinding the stored solid content. The provided cutter pump 12 is installed.

The water level detection sensor 11 is electrically connected to the main circuit control device (MCC) as shown in FIG. 11, and the electrical signal is transmitted to the main circuit control device (MCC) by sensing the water level detection sensor 11. Then, power is supplied to the cutter pump 12 by the main circuit controller (MCC).

The manure and the sewage stored in the anaerobic storage tank 10 by the cutter pump 12 are discharged along the transfer pipe 12a. The cutter pump 12 is preferably provided with a filtering net 15 around the cutter pump so that the cutter pump 12 does not malfunction due to a tissue, paper, or solid matter, or the suction port of the cutter pump 12 is not blocked.

For example, around the cutter pump 12 is provided with a filter net 14 made of a stainless plate-shaped body provided with a hole having a constant diameter, and prevents the excessively large solids flow into the filter net 14 to prevent the cutter pump ( At the same time, it is preferable that the suction port of 12) is not blocked and at the same time, the filter medium (not shown) filled in the anaerobic storage tank 10 is not crushed by the cutter pump 12 or transferred along the transfer pipe 12a.

In addition, the bottom of the anaerobic storage tank 10 may be further provided with a hop bar inclined at a predetermined angle. Hop bar 15 provides the action of collecting foreign matter, sludge or sediment, such as solids or tissue, introduced into the anaerobic storage tank 10 into one place.

In addition, the discharge pipe 13 through which the manure and sewage generated from the flush toilet 1b of the toilet is discharged, constitutes a screen 16 on the upper portion of the anaerobic storage tank 10, and may be introduced into the manure and sewage. It is installed to filter degradable solid foreign matter.

Solids and other precipitates collected by the hop bar 15 can be easily sucked by the cutter pump 12 and discharged through the transfer pipe 12a.

As shown in FIG. 3, the aerobic bioreactor 20 is a tank for storing and treating manure and sewage, which are connected to the anaerobic storage tank 10 and transferred along the transfer pipe 12a connected to the cutter pump 12. Inside the tank, the first reactor 21 and the first filter 22 are attached to the wall surface so as to be spaced a predetermined space from the bottom surface.

The first reactor 21 is a case 21a in which a porous plate is formed in a plate-shaped body made of a corrosion-resistant corrosion-resistant material such as plastic or stainless steel, and various kinds of microorganisms for providing a habitat for microorganisms in the case 21a. The media is filled.

The various media filled in the first reactor 21 dissolve natural minerals or waste synthetic resins having micropores, such as biowood chips in which microorganisms are cultivated, bioblocks that are microbial fixative strains, burned coal agglomerates, and volcanic stones, and have a rough surface. As a synthetic resin mediator having a large amount of fine grooves, the mediators may be alternatively or mixed.

The lower part of the first reactor 21 is provided with a first aeration device 23. As shown in FIG. 11, the first aeration device 23 includes an air pump 23a intermittently controlled by the main circuit controller MCC, and an diffuser 23b connected to the air pump 23a by piping. Consists of.

When the air pump 23a is driven, air is discharged from the diffuser 23b so that the inside of the water tank is exhaled. In the aerobic state, as the air contacts the surface of the media filled in the first reactor 21 through the pores formed in the case 21a, the nitrification of the aerobic microorganisms parasitic in the media is activated, and the nitrification reaction is activated, and the air pump 23a At the stop, the aerobic bioreactor 20 becomes anoxic and undergoes denitrification.

Aerobic bioreactor 20 is an exhalation state, the ammonium nitrogen contained in the wastewater (NH ₄ ⁺ -N) is a nitrite nitrogen (NO ₂ ^- N ^-) is converted to, nitrite nitrogen (NO ₂ ^{- -} N) is The nitrification reaction, which is then converted to nitrate nitrogen (NO ₃ ^-- N), proceeds. A microorganism fungus nitro consumption eggplant (Nitrosomonas), nitro bakteo (Nitrobacter) involved in nitrification, nitrification reaction of the nitro consumption eggplant bacteria ^{_{NH 4 + + 3/2 O 2 →}} NO 2 - + H 2 O + 2H + , and the nitrification of the nitro bakteo bacteria NO ₂ ^{+ +} 1/2 O ₂ ^- and proceeds to ^- → NO _3.

When the tank is in aerobic state, the microorganism oxidizes the substrate stored in the cell to obtain energy for the bioreaction, and uses the same to reabsorb the released phosphoric acid to store it in the cell in the form of polyphosphoric acid.

On the other hand, the tank is denitrifying microorganisms denitrification when the oxygen-free state and to push forward ^{_{(NO 3 - - → NO2 NO}} → N 2 O → N 2) releasing N ₂ to remove fly into the atmosphere, the microorganism is polyphosphoric acid in the cell Hydrolyze and release to phosphate.

Phosphorus released in the anaerobic state is fed to the microorganisms in aerobic state, at which time the excess phosphorus intake of the microorganisms and adsorbed by the media filled in the first reactor 21 may be removed.

In addition, the media filled in the first reactor 21 is aerobic microorganisms parasitic on the surface, anaerobic microorganisms parasitic in the inner micropores, aerobic microorganisms to store phosphorus in the cell while promoting the nitrification process, anaerobic microorganisms Denitrification proceeds to NO ₃ ⁻ , which releases N ₂ and removes organic matter.

The first filter 22 described above is configured to filter the sewage discharged by gravity when the sewage flowing into the aerobic bioreactor 20 rises above a predetermined amount, and the first filter 22 is made of plastic, FRP, stainless steel. Box made of a square or cylindrical with a corrosion-resistant material such as, the upper / lower part is open, the oyster shell, ganban stone, volcanic stone or other filtering media may be laminated on the net installed in the lower portion.

The filter medium is filtered so that sludge or fluid suspended matter contained in the sewage is not discharged while the sewage flows from the lower part of the first filter to the upper part by gravity, and the treated water passing through the filtering medium is upper part of the first filter. It is discharged through an outlet installed in the

Therefore, as described above, if the inside of the aerobic biological reaction tank 20 is intermittently aerated with air, as described above, the interior of the water tank is to remove organic matter, nitrogen and phosphorus while the aerobic and anaerobic states are alternately formed.

The flow rate adjustment tank 30 described above is used to denitrify and stabilize nitrogen contained in sewage while storing the treated water discharged from the first filter 22 of the aerobic bioreactor 20 as anoxic state, as shown in FIG. 4. As the water tank, the inner wall of the flow regulating tank 30 is driven by the water level detection sensors 32a to 32c electrically connected to the main circuit control device MCC as shown in FIG. 11, and the main circuit control device MCC. It is equipped with the transfer pump 31 which is controlled.

The water level detection sensors 32a to 32c detect the high, medium and low water levels of the flow regulating tank 30 and transmit an electric signal to the main circuit controller MCC to transfer the pump 31 by the main circuit controller MCC. Adjust the flow rate while controlling the drive time.

The flow rate can be adjusted by adjusting the transfer amount of filthy water by the difference in the driving time of the transfer pump 31. Sewage conveyed by the transfer pump 31 is transferred to the organic material extinction reaction tank 40 along the transfer pipe 33.

As described above, the organic material decay reaction tank 40 is filled with a wood chip (not shown) as shown in FIG. 5, and a watering device (41, water spray nozzle 41a) installed thereon and an organic material decay reaction tank. A heat generating means 42 for accelerating and activating the proliferation and metabolism of microorganisms parasitic in wood chips by installing on the inner wall of the 40 and an air dispersing device for intermittently supplying air to the wood chip layer {43, air pump 43a, diffuser 43b}.

The sprinkling nozzle 41a is connected to the transfer pipe 31 connected to the transfer pump 31 to sprinkle sewage transferred by the transfer pump 31 to the upper portion of the wood chip.

The heating means 42 is preferably a heating coil (42a) or other heating plate that is generated by the power source, the temperature of the wood chip layer by the heating means 42 is always maintained in the range of 60 ℃-65 ℃ It is controlled by a heat sensor (not shown in the figure) and a main circuit controller (MCC) electrically connected to the heat sensor to maintain the temperature of the wood chip layer so that the active conditions of the high temperature microorganism are active. Let's do it.

In general, in livestock wastewater with a high concentration load (30,000-50,000PPM), due to the high pollution load, the exothermic temperature alone maintains the active temperature of the high temperature microorganisms by 60 ° C only due to the high pollution load. In manure and filthy water, such as flush toilets, the pollutant load organic matter concentration (150 ~ 300PPM) is low, so a separate heating device is required for rapid decomposition activation by high temperature microorganisms.

Examples of denaturation of protein components include, for example, when denaturation begins at 20 ° C. (low temperature) for about 1 hour, and at 25-30 ° C. (medium temperature) for 30 minutes, and at 60 ° -65 ° C. At high temperature, rapid decomposition occurs in 10 minutes.

In addition, sludge sludge is small in the organic waste extinguishing tank, unlike slaughterhouse, in the toilet manure and sewage treatment, and sludge does not accumulate as in the livestock wastewater because it is introduced into the metabolic action in the aerobic bioreactor and filtered. Treatment efficiency can be secured sufficiently without a separate stirring device.

That is, the sewage water sprayed by the spray nozzle 41a is adsorbed during the residence and passage of the wood chip layer, and the inside of the wood chip is alternately formed by the air supplied intermittently and the anaerobic state of the wood chip. Anaerobic and aerobic microorganisms parasitic in and out of the pores and surface completely decompose and remove organic matter, nitrogen, phosphorus, etc. contained in the treated water, and the treated water passed through the wood chip layer is advanced through the discharge pipe 44 Discharged to 50.

The wood chip is to provide a habitat for microorganisms, oak or cedar may be used selectively, but the present invention employs cedar wood chips.

Through the technical filling of cedar wood chips by size, it is possible to filter out the solids as much as possible, and to be adsorbed while remaining as possible without clogging the sprinkled manure and sewage, the organic material filtered and adsorbed by the wood chips Decomposed by microorganisms inhabiting wood chips.

Woodchips cultivate microorganisms by maximizing the surface area and porosity of wood chips. Here, the organic material is adsorbed or attached to the pores of the wood chip, and manure and sewage are treated in the process of microorganisms ingesting the organic material as nutrients.

Cedar wood chips used in the above-mentioned treatment process are composed of cellulose (65-85%), lignin (10-25%), pentosan (5-10%), etc. The lignin component is continuously eluted during the treatment of manure and sewage, and the treated water becomes dark red as it is mixed with the treated water. As the amount of the pigment is eluted, the treated water becomes dark black.

Therefore, the treated water can remove organic matter, nitrogen, phosphorus, etc. in the course of passing through the wood chip, but the chromaticity of the treated water is discharged in a dark red color which is a considerable distance from the clear water by eluting the lignin pigment.

Although most of the prior art describes the treated water passing through the wood chip as a treated water, even if organic matter, nitrogen, phosphorus, etc. have been treated stably, the water quality is strictly expressed by the lignin component of the wood chip. Since it is a very poor condition, it is difficult to perform a function as a substantially stable washing water unless the lignin pigment is removed.

Therefore, wood chips used in manure and sewage treatment, especially wood chips used in a non-discharge circulating flush toilet treatment system for recycling, must be completely preceded by the removal treatment of the pigment elution component.

The wood chip used in the present invention is a wood that has been specially treated to remove the pigment component eluted from the wood chip with the know-how obtained during years of research and development and experimental pilot operation. Use chips.

Microorganisms inhabiting cedar wood chips are classified into bacteria and protozoa, and as floc-forming bacteria, mainly oogloea ramigera and Sphearotilus natans , Achromobacter, Alcaligenes, Bacillus, Flavoacterium, Phseudomonas, and the like. Protozoa are mostly ciliary insects, and are a hybrid of aerobic microorganisms that require oxygen for organic decomposition and anaerobic bacteria that do not require oxygen.

The microbial floc propagated by the wood chips digests and decomposes sludge mixed with organic matter in sewage, and when manure and sewage are sprayed, they are adsorbed while staying and passing through the wood chip layer filled with the sprinkled manure and sewage. In addition, high-temperature microorganisms generate heat during the decomposition of organic matter, which activates the activity of aerobic and anaerobic microorganisms that inhabit wood chips. The anaerobic microorganism is active at room temperature, the digestive metabolism is active, the temperature of the wood chip body is raised to 60-65 ℃ degree of activity of the high temperature microorganism is further enhanced.

The manure and sewage treatment method using wood chips is a biological decomposition of carbohydrates and nitrogen compounds by aerobic microorganisms, carbohydrates are decomposed into carbon dioxide and water by ingesting oxygen, and carbon organic matter is removed by using oxidative energy generated during the decomposition process. And as nitrification proceeds, decomposition of organic matter is performed.

Anaerobic microorganisms absorb carbon dioxide, methane gas, ammonia, hydrogen sulfide, etc. without oxygen supply and decompose organic matter.

The advanced treatment tank 50 is a water tank for storing and treating the treated water discharged from the organic material extinction reaction tank 40, as shown in Figure 6, the first reactor 21, the aeration device 23, described above The 2nd reactor 51 like the 1st filter 22, the aeration apparatus 53, and the 2nd filter 52 are provided.

The second reactor 51 is composed of a corrosion resistant material, for example, a case 51a in which pores are formed in a plastic or stainless steel plate, and an advanced processing medium (not shown) filled in the case 51a. It is. The various media filled in the second reactor 51 are mixed with a certain ratio of several kinds of natural mineral powders such as oyster shell, ceramic ball, calcite, lime, loess, elvan, powder, activated carbon powder, zeolite powder, and illite powder. (Mini Ball) It is filled with special media for advanced processing that has fine porosity by sintering at 800-1,000 ℃ heat in the shape of cube.

In the aeration device 53, the air is discharged from the diffuser 53b when the air pump 53a is driven, and the inside of the water tank is exhaled. In the aerobic state, the filter medium and the treated water filled in the second reactor 51 through the pores formed on the surface of the case (51a) is abandoned by the air, and the advanced processing filter and the treated water are included in the advanced processing filter Nitrogen, phosphorus, color, odor, etc. are decomposed and removed through reactions such as nitrification, denitrification, and decomposition of harmful components by various components and microorganisms, and the advanced treatment tank 50 is oxygen-free when the air pump 53a is stopped. It becomes a state.

As described above, the aerobic state and the anoxic state of the advanced treatment tank 50 are intermittently repeated, so that nitrification and phosphorus excess intake and organic matter removal, denitrification and dephosphorization reaction, and harmful component decomposition are performed inside the advanced treatment tank 50. Alternately.

As shown in FIG. 7, the second filter 52 has the same configuration as that of the first filter 22 described above, and the treated water that has passed through the second filter 52 passes through the outlet 54. To be discharged.
