FIG. 3 is a view of a toilet bowl of a resource circulation type toilet according to the present invention, and FIG. 4 is a sectional view of a toilet bowl of a resource circulation type toilet according to the present invention.

As shown in FIG. 2, the toilet 100 is provided with a cover on which a toilet seat is located and covers the toilet 100. 3 and 4, the present embodiment illustrates a toilet having a bowl in which a toilet bowl 100 is formed with a manure discharge port. Of course, the present invention is not limited to this, and a conventional toilet seat in which a user is squatting can be used. A conveyor 130 is provided under the toilet 100.

The conveyor 130 transports the faeces and urine passing through the outlet of the manure. Here, the conveyor 130 is formed in a triangular shape and includes a urine conveyor face 134, which is positioned below the manure outlet and downwardly inclined to one side, and a counterweight conveyor face 132, which is downwardly inclined to the other side. Slits or through holes are formed in the conveyor 130 so that urine can be conveyed through the slit or through hole to the liquid tank 300 through the conveyor 130 and the urine transfer pipe. Also, the faeces which can not pass through the slit or the through hole moves along the rotating direction of the conveyor 130 and is transferred to the composting tank 200 through the faeces transfer pipe. Here, it is effective that protrusions are formed on the surface of the conveyor 130 in order to allow the feces to be conveyed along the conveyor 130. Of course, in the present invention, the conveyor 130 is a triangular shape. However, the present invention is not limited thereto, and a general flat conveyor 130 may be used. In this case, the flat conveyor 130 may be positioned horizontally without inclining under the outlet of the manure outlet, or may be inclined such that the area of the conveyor 130 in one direction is positioned lower than the area of the conveyor 130 in the other direction .

6 is a perspective view of a stirrer of a circulating toilet according to the present invention.

The compost tank 200 composts the added feces by adding the added feces. To this end, the composting tank 200 includes a stirrer 210 for stirring the transported feces with additives and the rotation of the blade 211, and a storage space for storing the compost feces stirred in the stirrer 210 for composting. Here, the additive may be at least one of a seed germ and a sawdust as a solid additive. Accordingly, the present invention can include a stool seed adder and a sawdust adder.

In the apparatus for adding a stool fungicide, a fungicide is added to a feces flowed into an agitator (210). The present invention exemplifies a zoonotic strain of the genus Nitrosomonas. In addition, the apparatus for adding a seed bacterium controls the amount of the seedling to be added according to the weight of the feces introduced into the stirrer 210, preferably 20 ml of the seedling is added per 300 g of the stool. To this end, the apparatus for adding a stool fungicide includes a stool weight measuring sensor for measuring the weight of a feces introduced into the stirrer 210, a stool weight adding sensor for adding a staphylococcus augment according to the weight of the stool measured by the stool weight measuring sensor, .

FIG. 7 is a graph of a vigorous extinguishing process using a sterilizing agent in a resource circulating toilet according to the present invention, and FIG. 8 is a graph of modeling of a vigorous digestion using a K value in a resource circulating toilet according to the present invention. Fig. 7 shows the results of using Nitrosomonas aeruginosa. Four 500 ml containers each containing 300 g of feces were prepared. In addition, 0, 5, 10, 20 ml of the fungicide was added to each stool sample at a temperature of 15 to 20 degrees Celsius, and the sample was not stirred.

Referring to FIG. 7, it can be seen that the use of a fungicide is effective in reducing the weight of collected feces. About 20% of the fungus can be used to digest about 60% of the stool for 15 days. The K value of each sample is shown in Fig. 7, which means that the larger the K value, the better the digestion process.

Referring to FIG. 8, there is shown a first-order equation of data modeling using K values. When 10 ml of the fungicide and feces are mixed, the following tendency is shown.

FIG. 9 is a graph showing a temperature change of a feces and a stool feces mixture in a resource circulating toilet according to the present invention.

Referring to Fig. 9, no significant changes in the temperature of the samples were observed.

The sawdust addition device supplies the sawdust to the agitator (210). Of course, the sawdust is added when the feces flows into the stirrer 210, and the stirrer 210 stirs the introduced feces and the sawdust, and then transfers the feces to the storage space. Here, the sawdust added by the sawdust addition device prevents the heat generated in the composting process of the feces from escaping due to the effect of the warming, so that the digestion process of the higher efficiency occurs.

FIG. 10 is a graph showing a digestion process using a solid additive in a resource recirculation toilet according to the present invention.

Referring to Fig. 10, it can be seen that, during the 15 days of the feces digestion process, the sawdust in the solid additive, sawdust and ash and the sawdust in the rice husk show a higher efficiency compared to ash and rice husk have.

11 is a graph of temperature changes of feces and solid additives in a resource circulation type toilet according to the present invention.

Referring to FIG. 11, it can be seen that the effect of fine sawdust particles also appears at the temperature change of the samples. That is, the sawdust serves to keep the heat generated in the composting process, and the sawdust is compressed and the heat does not escape from the interior of the sample, thereby increasing the efficiency of the digestion process.

12 is a side cross-sectional view of a liquefaction tank in a resource circulation type toilet according to the present invention.

The liquefaction tank (300) liquefies the inflowed urine. To this end, the liquefaction tank 300 is provided with a partition wall 310, a device for adding a urine bactericide, and a device for adding a urine solid additive.

At least one partition wall 310 is formed in the liquid storage tank 300 so as to cross the liquid storage tank 300. The urine introduced into the liquid tank 300 by the barrier rib 310 moves over the barrier rib 310 and flows through the liquid tank 300. In the present invention, three reservoirs 310, that is, first to third seals 311, 312 and 313 are provided in the reservoir tank 300. Thus, in the reservoir tank 300, That is, the first to fourth liquid storage spaces R1, R2, R3, and R4 are formed. Accordingly, the urine flows into the first liquid storage space R1. When a predetermined amount or more flows into the first liquid storage space R1, the urine flows over the first partition wall 311 and moves to the second liquid storage space R2. When a predetermined amount or more of urine flows into the second liquid storage space R2, the urine flows over the second partition wall 312 to the third liquid storage space R3, and the urine in the third liquid storage space R3 also reaches a certain amount , The third barrier rib 313 flows over to the fourth liquid storage space R4. Here, the urine moved to the fourth liquid storage space R4 is a urine to be finally used as fertilizer. Although the present invention has exemplified the first to fourth liquid storage spaces R4, it is not limited thereto. That is, there may be four or more liquefied spaces, and seven liquefied spaces are effective. This is because the urine stored in each liquefied space is not mixed with each other by the partition wall, and finally the urine of the seventh day is used as the liquid. In the present invention, the partition wall 310 is provided in the liquid tank 300 so that the liquid to be liquefied can be prevented from being mixed with each other in the liquid pool space, thereby increasing the liquefaction efficiency of the urine.

The apparatus for adding the urine fungicide adds a bactericide to the liquid tank 300. Herein, the nitrification agent exemplifies nitromonas fungi. This is the same as the fungi added to the feces. However, the present invention is not limited thereto, and the pesticide added to the urine and the feces may be different from each other, or a nitrification agent other than nitromonas may be used. Also, in order to minimize the loss of ammonia and odor, the urine fungicide addition apparatus is supplemented with 10 ml of a bactericide in 1 liter of urine. To this end, the apparatus for adding a urine bacterial fl uid includes a sensor for measuring a urine amount introduced into the liquid tank 300 and a urine bacterial agent addition module for injecting the organism depending on the measured urine amount.

13 is a graph of ammonia concentration change with time in a circulating toilet according to the present invention. Here, a 1-liter beaker filled with urine was used as a batch bioreactor, and a sample containing the non-killed bacteria and a sample containing 5 to 50 ml of the killed bacteria were used. Also, the amount of pH, TN, NH ₃ , NH ₄ ⁺ and NO ₃ ^- was measured for 15 days at a constant temperature of 15 ° C. Here, the temperature of 15 degrees Celsius is the average temperature of the ordinary urine tank, and is set because the nitrification process by Nitrosomonas does not change much at 15 degrees Celsius. In addition, the experiment was conducted three times in total and the average value was used. Experiments were carried out using the US Environmental Protection Agency's standard method (1983) using the UV / Visible Spectrophotometer Model HS-3300 and the pH was measured using the Aquaread Aquaprobe model AP ?? 2000.

Referring to FIG. 13, it can be seen that the ammonia concentration trends are different from each other in the different samples, and the same tendency is observed with respect to pH, TN and ammonium. Here, as a result, the amount of ammonia is reduced, and ammonia is changed into a substance such as ammonium or nitrate, or it is turned into a gas, which is separated and then decreased. Also, the amount of ammonia was kept constant from the eighth day of the experiment. That is, it can be seen that the addition of the bactericidal agent stabilizes early.

FIG. 14 is a graph showing a change in nitrate concentration with time in a resource circulation type toilet according to the present invention. FIG.

Referring to Figure 14, the addition of 1 ml / l of the fungicide produces a small amount of nitrate and allows the sample to retain many ammonia ions. This makes the sample more alkaline. However, there is no significant change in temperature.

The urine solid additive addition device adds a solid additive to the urine introduced into the liquid tank 300. Here, the solid additive exemplifies a spherical carrier which absorbs ammonia.

FIG. 15 is a graph showing changes in ammonia concentration over time of various solid additives in a resource circulation type toilet according to the present invention. FIG.

Referring to Figure 15, Figure 15 shows the change in ammonia in the urine with different solid additives added. Here, pine cones, chestnut, rice straw, GAC, sponge and spherical carrier were used as solid additives. The inclusion of solid additives mainly reduces the amount of ammonia through physical absorption, and the pH, TN and ammonium have the same trend.

16 is a graph showing changes in nitrate concentration with time of various solid additives in the resource circulation type toilet according to the present invention.

Referring to FIG. 16, the concentration of nitrate varies depending on the type of the solid additive. Among all solid additives, the spherical carrier shows good functionality as it produces less nitrate than other solid additives. Rice straw also shows good functionality in absorbing ammonia, but it can not be used as fertilizer because it produces a large amount of nitrate by pH reduction. On the other hand, there was no significant change in temperature.

FIG. 17 is a graph comparing (a) stabilized pH (b) and nitrate concentration after 15 days in nitrosomonas sp. At different concentrations in the resource circulation type toilet according to the present invention.

Referring to FIG. 17, it can be seen that adding 10 ml of the bactericide to 1 liter of urine results in minimal ammonia loss and odor, so that it is the optimum concentration. It also reduced the time required to stabilize NH ₃ in the most effective manner and reduced possible nitrate contamination by generating small amounts of NO ₃ ^- .

Meanwhile, the present invention can clean the conveyor 130 with the liquefied urine stored in the above-described liquid tank 300. To this end, the present invention comprises a moving means cleaning device.

The moving means washing apparatus receives liquid urinated in the liquid tank 300 and injects the liquid into the conveyor 130 to wash the moving means including at least one of the conveyor 130 and the toilet bowl. This can be performed by injecting liquefied urine into the moving means through nozzles provided at one end or the other end of the conveyor 130 to prevent foreign substances such as feces from adhering to the moving means. Needless to say, a rotating brush or an air jet nozzle may be provided at the rear end of the nozzle so as to allow a thin foreign matter to fall off cleanly. Furthermore, the present invention has not only liquidized urine, but also a separate rainwater storage facility, and it is also possible to clean the moving means with stored rainwater. Of course, it is also possible to mix the stored rainwater and the liquefied urine and spray it through the nozzle to remove the foreign matter adhering to the moving means.

In addition, the present invention may further comprise a toilet management module for monitoring the current state of the circulating toilet. In this case, the toilet management module can display the current state of the toilet on the terminal of the administrator, and can be implemented in the form of an application on the terminal. It is also effective that the toilet management module monitors the current state of the toilet from the sensor in the toilet, and the manager contacts the toilet management module of the toilet with the terminal to monitor the current state of the toilet. For this purpose, an ammonia detection sensor and a urine level sensor may be installed in each space between the partition walls 310 in the liquefaction tank 300. In the composting tank 200, a sensor for sensing the amount of composted compost Can be installed. In addition, a sensor may be provided in the space where the toilet bowl 100 is installed, and a sensor for detecting the rotation of the roller driving the conveyor 130 to determine whether the conveyor 130 is operating normally. The present invention can monitor the status monitored by such sensors from an administrator.
