Abstract
The present invention relates to a zero-discharge circulation-flushing toilet, and more particularly, to a zero-discharge circulation-flushing toilet that detects pollutants in feces and urine transferred from a toilet bowl at an early stage and notifies a manager when an abnormality occurs.
Description
Technical Field
The present invention relates to a zero-discharge circulation flushing toilet, and more particularly, to a zero-discharge circulation flushing toilet that detects pollutants in feces and urine transferred from a toilet bowl at an early stage and notifies a manager when an abnormality occurs.
Background
The zero discharge circulation flushing toilet is a toilet which does not discharge feces, urine and water, but internally treats them to circulate them as toilet treatment water. In such a zero-discharge circulation toilet, a waste treatment apparatus such as an aerobic biological reaction tank, a high-level treatment tank, or a biological reaction tank is used to treat waste discharged from a toilet bowl. Further, the above-described configuration repeats the process of converting the excrement and urine into the treated water again and supplying the treated water to the toilet bowl.
However, in such a conventional zero-emission circulation-flushing toilet, when a user discards an acidic solution such as hydrochloric acid, there is a problem that all microorganisms are killed by flowing into an aerobic biological reaction tank or the like. In this case, in order to reuse the zero-emission circulation-type toilet, it is necessary to perform an operation of discharging the excrement from the entire excrement treatment apparatus and culturing the microorganisms again to stabilize the excrement. However, this process takes at least 15 days or more, and therefore, the zero-discharge circulation flushing toilet cannot be used in the corresponding period.

Detailed Description
The above objects, features and advantages will be described in detail with reference to the accompanying drawings, whereby a person having ordinary skill in the art to which the present invention pertains can easily carry out the technical idea of the present invention. In describing the present invention, in the case where it is judged that a detailed description of a known technology related to the present invention makes the gist of the present invention unclear, a detailed description thereof will be omitted. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar structural elements.
Fig. 1 is a schematic sectional view of a zero discharge circulation flushing toilet of the present invention.
As shown in fig. 1, the zero discharge circulation flushing toilet of the present invention includes: a toilet 100; a pipe 200 for transporting the excrement of the toilet 100; the contaminant detection device 300 is provided in the pipe 200; a feces-urine treatment device 400 for treating feces and urine transferred through the piping 200 with washing water and supplying the treated feces and urine to the toilet 100; and a pollutant detection information transmitter (not shown) for transmitting pollutant detection information to the manager's terminal when a pollutant is detected in the pollutant detection device 300.
The toilet 100 receives feces and urine from a user and discharges the feces and urine to the pipe 200, and the toilet 100 of the present embodiment includes a toilet body, a cover covering an upper portion of the toilet body, and a tank for flowing water to the toilet body, by which a general toilet bowl is exemplified in the present embodiment. However, the present invention is not limited to this, and any configuration of the toilet bowl 100 may be applied if the pipe 200 for transporting the excrement and urine may be provided.
Fig. 2 is a cross-sectional view enlarging a dotted line area of fig. 1.
The pipe 200 transfers the excrement of the toilet 100 to an excrement storage (anaerobic digestion retention tank described later). As shown in fig. 2, the pipe 200 includes: a main pipe 200 for transporting excrement; and a discharge passage 220 for discharging the excrement stored in an excrement storage line 211, which will be described later.
A "U" -shaped feces-urine storage line 211 is formed at the transfer line 210 to easily detect contaminants possibly mixed with feces and urine by the sensor 310. That is, in the present embodiment, the transfer pipe 210 is bent to the left or right side in a longitudinal direction at the lower end of the toilet bowl 100, and the feces-urine storage pipe 211 is formed at the bent region. With this configuration, a part of the excrement transferred to the transfer line 210 is stored in the excrement storage line 211. The transfer line 210 is bent to the left or right and then bent downward.
When the toilet 100 is flushed, the discharge line 220 discharges the excrement which is not completely discharged through the transfer line 210 and remains in the excrement storage line 211. The discharge line 220 is connected to the feces-urine storage line 211 and the transfer line 210 from the upper portion to the lower portion, and discharges the feces and urine in the feces-urine storage line 211 to the transfer line 210 by its own weight. The discharge line 220 may be connected to an anaerobic digestion retention tank (410 of fig. 5) described later, and the present embodiment is exemplified by being connected to a transfer line 210 region located at the front end of the anaerobic digestion retention tank (410 of fig. 5), that is, a downwardly curved region of the transfer line 210. If the excrement stored in the excrement storage line 211 continues to contact the sensor 310, the sensor 310 may be corroded. Therefore, the discharge line 220 prevents the sensor 310 from being corroded by discharging the excrement of the excrement storage line 211 after the sensor 310 is in contact with the excrement. Also, the excrement stored in the excrement storage line 211 cannot be discharged rapidly so as not to be detected by the sensor 310, and therefore, the diameter of the discharge line 220 needs to be sufficiently smaller than that of the transfer line 210 so that the excrement is discharged slowly.
On the other hand, in the present embodiment, a fecal discharge adjusting device may be provided for adjusting the discharge speed of the fecal stored in the fecal storage line 211.
Fig. 3 is a schematic sectional view of a transfer pipe line to which a feces-urine discharge regulation device is applied in the zero-discharge circulation flushing type toilet of the present invention.
The excrement discharge adjusting device is used for adjusting the discharge speed of excrement discharged to the discharge pipeline 220. For this purpose, the feces-urine discharge regulation device comprises: opening and closing devices 221 and 222 for discharging excrement and urine for adjusting whether to discharge excrement and urine; and a feces-urine discharge regulation storage tank 223 for temporarily storing the feces and urine passing through the feces-urine discharge opening/ closing devices 221, 222.
The opening/ closing device 221, 222 for discharging excrement and urine includes: a feces/urine discharge opening/closing line 221 for expanding the diameter of a part of the discharge line 220; and a fecal discharge opening/closing ball 222 provided inside the fecal discharge opening/closing line 221. The excrement flowing into the discharge line 220 flows into the excrement discharge regulation storage tank 223 through a space between the excrement discharge opening/closing line 221 and the excrement discharge opening/closing ball 222. However, since the excrement is rapidly discharged at an early stage when the toilet bowl 100 discharges the excrement, the excrement in the excrement discharge regulation storage tank 223 flows backward when the excrement stored in the excrement discharge regulation storage tank 223 is full, and the excrement discharge closing ball 222 closes the upper portion of the excrement discharge opening/closing pipe 221. Accordingly, a part of the excrement discharged from the toilet 100 is stored in the excrement discharge regulation storage tank 223 in an early stage, and the rest is rapidly transferred through the transfer pipe 210. When the excrement in the excrement discharge adjustment storage tank 223 is discharged to the transfer pipe 210, the excrement discharge opening/closing ball 222 drops on the upper portion of the excrement discharge opening/closing pipe 221. Accordingly, the excrement stored in the excrement storage line 211 is discharged through the discharge line 220. Of course, the fecal discharge opening and closing ball 222 closes the fecal discharge opening and closing line 221, detects a pollutant by the sensor 310 while the fecal is stored in the fecal storage line 211, and then the fecal stored in the fecal storage line 211 is discharged through the discharge line 220, so that the sensor 310 can be prevented from being damaged. On the other hand, the fecal discharge closing ball 222 may be made of a material that can be raised by the water pressure of the fecal, for example, a material such as a foam or a resin.
Fig. 4 is a schematic sectional view of a transfer pipe installed with a pollutant detecting device in the zero discharge circulation flushing type toilet of the present invention.
The pollutant detecting device 300 is located in the excrement storage pipeline 211 and is used for detecting pollutants in excrement. To this end, as shown in fig. 4, the pollutant detecting device 300 includes: a sensor 310 for directly detecting pollutants of the excrement and urine; and a cover 320 for protecting the sensor 310 from the feces and urine.
The sensor 310 directly detects contaminants that may be contained in the excrement transferred to the transfer line 210. In the present embodiment, the sensor 310 is an acidity detection sensor. Of course, the present invention is not limited to this, and the present invention can be applied to various sensors 310 such as the temperature detection sensor 310. At least a part of this sensor 310 is located in the manure storage line 211 to be in contact with the manure stored in the manure storage line 211.
The cover 320 surrounds the sensor 310 for protection and allows the inflow of the excrement and urine through a portion of the area. To this end, the cover 320 includes: a cover body 321 for protecting the sensor 310; and a filter net 322 provided at the open lower end of the cover body 321 for allowing the excrement and urine to flow into the cover body 321.
The cover body 321 protects the sensor 310 from the feces flowing into the upper portion of the sensor 310. For this purpose, the cover body 321 preferably surrounds the top and side surfaces of the sensor 310, and in the present embodiment, the cover body 321 is a rectangular box-shaped cover body 321 having a hollow interior. However, the present invention is not limited to this, and the present invention can be applied to a cover main body 321 having a polygonal box shape including a cylindrical shape, an elliptic cylindrical shape, or a triangular box shape. The upper portion of the cover body 321 may have a streamline shape, for example, a semicircular shape, so that the excrement flowing into the upper portion of the cover body 321 is easily transferred through the transfer pipe 210. The lower portion of the cover body 321 is opened to mount a filter 322 described later.
The filter net 322 is provided at a lower portion of the cover 320 to allow the excrement to flow into the lower portion of the cover 320. The filter screen 322 is in a mesh form, so that large feces contained in the feces and urine are prevented from flowing into the filter screen, and only the liquid feces flow into the cover 320 and come into contact with the sensor 310.
Fig. 5 is a schematic view of a device for treating feces and urine in a zero-discharge circulating flushing toilet of the present invention.
The excrement treatment device 400 stores excrement transferred through the transfer line 210, treats the stored excrement, and resupplies the treated excrement to the toilet 100 with washing water. For this, as shown in fig. 5, the excreta treatment device 400 comprises an anaerobic digestion retention tank 410, a flow rate regulation retention tank 420, an aerobic biological reaction tank 430, an organic matter elimination reaction tank 440, a high-order treatment tank, a biological reaction tank 460, a decolorizing and disinfecting filtration tank 470, and a treated water storage tank 480.
The anaerobic digestion retention tank 410 stores the manure transferred through the transfer line 210 in the toilet 100. The anaerobic digestion retention tank 410 reduces homogenization and load of organic suspended matter contained in the excrement and urine by anaerobic digestion by microorganisms. Thus, ammonia (NH) may be reduced or removed3) And the like.
In another aspect, the present invention may provide a plurality of anaerobic digestion detention tanks 410. In this case, the transfer line 210 is branched and connected to each of the plurality of anaerobic digestion/stagnation tanks 410, and the unused anaerobic digestion/stagnation tank 410 is closed by a valve or the like to use only one anaerobic digestion/stagnation tank 410. In this case, only the used anaerobic digestion retention tank 410 communicates with the flow rate adjustment retention tank 420, and the rest is closed by a valve or the like. This is to open the valves of the other anaerobic digestion retention tanks 410 and use them during the reforming of the corresponding anaerobic digestion retention tank 410 when the anaerobic digestion retention tank 410 to be used is contaminated with a contaminant. In this case, a toilet may also be used during the reconditioning of the contaminated anaerobic digestion retention tank 410.
The anaerobic digestion retention tank 410 may transfer the excrement and urine to the flow rate control retention tank 420 by a pump. In this case, in the present embodiment, the second contaminant detection device 300 is provided in the pump, and the contaminant can be detected in the excrement transferred from the anaerobic digestion retention tank 410 to the flow rate adjustment retention tank 420. In the case of the pollutants flowing from the toilet bowl 100, even if the pollutants are transferred to the anaerobic digestion retention tank 410, the concentration of the pollutants may become such that the activity of microorganisms cannot be suppressed when the pollutants are diluted with the conventionally stored feces and urine. However, if the concentration of the pollutants in the excrement and urine transferred from the anaerobic digestion retention tank 410 to the flow rate adjustment retention tank 420 becomes higher than a predetermined level, serious pollution may be caused. Therefore, it is preferable that, when the concentration of the contaminant in the excrement transferred from the anaerobic digestion retention tank 410 to the flow rate adjustment retention tank 420 becomes a predetermined level or more, the operation of the pump is stopped to prevent the transfer of the contaminated excrement to the flow rate adjustment retention tank 420, and the contaminant detection information is transmitted to a designated manager.
The flow rate adjusting residence tank 420 moves to the aerobic biological reaction tank 430 by adjusting the flow rate of the manure moved from the anaerobic digestion residence tank 410 by the pump. The predetermined amount of the liquid manure is transferred to the aerobic biological reaction tank 430 through the digestion decomposition filter device, compared to the inflow amount of the liquid manure into the flow rate regulation retention tank 420. Further, a water level detection sensor 310 may be provided in the flow rate control retention tank 420, and when a predetermined water level is reached, the excrement and urine may be transferred to the aerobic biological reaction tank 430 by a pump.
The aerobic biological reaction tank 430 performs an aerobic oxidation action of activating the flow rate of the excrement and urine transferred from the flow rate regulation retention tank 420 by passing through a bioreactor (reactor) and adsorbing and culturing microorganisms. Wherein the bioreactor comprises a housing in which a porous plate is formed in a plate-like body made of a material such as plastic or stainless steel, and the interior of the housing can be filled with a plurality of members providing habitats for microorganisms. Further, an aeration apparatus is provided at the lower part of the bioreactor, so that the organic matter can be subjected to oxidative decomposition and removal treatment by aeration. Wherein, the aeration device can include: an air pump intermittently controlled by the control device; and the gas generating pipe is connected with the air pump.
The organic substance destruction reaction tank 440 is filled with wood chips for adsorbing and culturing microorganisms, and a sprinkling device for sprinkling excrement and urine is provided at the upper part thereof. In addition, the floating organic substances of the excrement and urine transferred from the aerobic biological reaction tank 430 can be continuously decomposed and eliminated.
The height treatment tank 450 removes residual organic substances, nitrogen, phosphorus, color, harmful bacteria, and the like from the excrement and urine supplied from the organic substance elimination reaction tank 440. This is because the media components are dissolved in a predetermined amount and the residual organic substances, nitrogen, phosphorus, color, harmful bacteria, and the like are removed by physical contact aeration of the sewage and the highly treated media (ball, block, and the like) by the air supply of the reactor.
The bio-reaction tank 460 is filled with a wood chip inside, and a watering device is provided at the upper portion. The present invention also includes an air generating device for intermittently supplying air to the wood chip. Thus, in the biological reaction tank 460, the excrement and urine transferred in the height treatment tank 450 is sprinkled to the upper portion of the wood chip by the sprinkling device, and the sprinkled excrement and urine alternately make the chip layers in an aerobic state and an anaerobic state by a process of flowing and passing through the interior of the wood chip and air intermittently supplied by the gas generating device. In addition, by the microorganisms parasitizing the wood chip, organic substances, nitrogen, phosphorus, and the like contained in the feces and urine are decomposed and removed.
The decolorizing and sterilizing filter tank 470 removes chromaticity, harmful bacteria, etc. from the excrement and urine treated in the biological reaction tank 460 by adsorption filtration using granular activated carbon and a decolorizing and sterilizing medium (media). However, the decolorizing sterilization filter tank 470 of the present embodiment may be replaced with an ozone bar. And, the excrement and urine treated in the decoloring sterilizing filter tank 470 becomes treated water.
The treated water storage tank 480 stores the treated water treated in the decoloring sterilizing filter tank 470. The treated water stored in the treated water storage tank 480 is supplied as the washing water of the toilet 100.
When the pollutant detection device 300 detects a pollutant from the feces and urine, a pollutant detection information transmitter (not shown) transmits pollutant detection information to a designated manager terminal. In the case where the pollutant detection device 300 includes only the acidity detection sensor 310, the pollutant detection information includes only information on whether or not the pollutant is detected. Of course, the present invention is not limited thereto, and even if the pollutant detecting device 300 includes only the acidity detecting sensor 310, the pollutant detection information may include the acidity level, the pollutant detection time. Such a pollutant detection information transmitter may be a terminal such as a server or a personal computer connected to the pollutant detecting device 300 by wire or wirelessly.
As described above, in the present invention, the transfer line 210 for transferring the excrement is formed into the excrement storage line 211 in a "U" shape, and the pollutant detecting device 300 is installed in the excrement storage line 211, so that the pollutant contained in the excrement is detected at an early stage and notified to the manager. In the present invention, the fecal sample storage pipe 211 is connected to the discharge pipe 220, and if the pollutant detecting device 300 detects a pollutant contained in the fecal sample, the fecal sample is prevented from remaining in the fecal sample storage pipe 211, thereby preventing the pollutant detecting device 300 from malfunctioning. In the present invention, the discharge line 220 is provided with a fecal discharge adjusting device, thereby sufficiently providing time for the contaminant detection device 300 to detect the contaminant in the fecal stored in the fecal storage line 211. In the present invention, the second contaminant detection device 300 is provided in the pump or the connection line that transfers the liquid from the anaerobic digestion retention tank 410 to the flow rate adjustment retention tank 420 to detect the contaminant in the excrement transferred to the flow rate adjustment retention tank, thereby more accurately detecting the contaminant.
As described above, the present invention is explained with reference to the drawings, but the present invention is not limited to the embodiments and drawings disclosed in the present specification, and various modifications can be made by those skilled in the art to which the present invention pertains. Meanwhile, in the description of the embodiments of the present invention, even if the operational effect of the structure of the present invention is not explicitly described, the effect predictable by the corresponding structure should be recognized.
