DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manure treatment apparatus used in a flush toilet which can be used in a place where water resources are small, such as a mountain area.

[0002]

2. Description of the Related Art Recently, sanitary simple flush toilets have become widespread even in places where sewerage facilities are not fully equipped. This type of flush toilet compresses manure and stores it in a tank, etc., and periodically collects it with a vacuum car, etc., but it is assumed that manure is collected, so vacuum car can not be put in It cannot be installed in mountainous areas or in developing countries where there is no system for collecting manure by vacuum car.

[0003] Therefore, in such a place, a primitive so-called manure pool is dug, manure is stored in the manure pool, and the manure is left to stand. Re-digging into
It is being pumped by hand and used as organic fertilizer. When manure from humans and livestock is used as an organic fertilizer, not only in such mountains but also in the fertilizer, the manure is temporarily stored in the fertilizer, and is used by spreading it in fields as needed.

[0004]

However, since manure contains many Escherichia coli and other pathogenic bacteria derived from the intestinal tract of humans and animals, if it is used as it is as a fertilizer, it may contaminate the soil. However, there is a problem that maggots are produced and fly is generated in large quantities, which is not hygienic. As in general sewage treatment, it is sanitary to disinfect manure using a strong oxidizing agent such as chlorine, but when it is scattered in the fields, soil becomes acidic due to residual chlorine contained in the disinfected manure. This causes a problem that the crop does not grow.

As a method of disinfection without using an oxidizing agent such as chlorine, heat disinfection is known. However, when a large sewage tank is directly heated to heat treat sewage containing manure, Not only is a large-capacity heater required to heat the sewage tank necessary, but also sewage such as manure has a large amount of solids and heat is difficult to convection, so it has been difficult to heat the whole to a predetermined temperature.

[0006] In this case, if the sewage is stirred, the heat is uniformly transmitted to the whole. However, a separate stirrer must be provided, which not only increases the running cost for maintenance of the stirrer, but also increases the cost of the stirrer. There is also a problem that the system becomes complicated and the equipment cost increases. Therefore, the present invention has an extremely simple configuration without using a stirrer or a large-capacity heater,
Another technical object is to heat a large amount of wastewater including manure with a small amount of energy so that the wastewater can be sterilized to the extent that it can be used as an organic fertilizer as it is.

[0007]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention provides a wastewater tank for storing manure together with its washing water, and a method for boiling manure and water flowing from the wastewater tank through an inflow pipe. A high-temperature chamber for sterilizing the water, a solid-liquid separation tank for separating sterilized manure and water discharged from the high-temperature chamber via a discharge pipe, and a water purification tank for storing the separated water. Is installed at a position lower than the liquid level of the sewage tank, the solid-liquid separation tank is installed at a position higher than the liquid level of the sewage tank, and the inflow pipe is piped so as to open near the bottom surface in the high temperature chamber. And the discharge pipe is connected to the ceiling of the high-temperature chamber by opening to the ceiling.

[0008]

According to the present invention, since the high-temperature chamber is installed at a position lower than the liquid level of the sewage tank, the sewage in the sewage tank can be removed via the inflow pipe by a water level difference without using a pump or the like. At this time, at this time, the drain pipe is also filled with sewage to the same level as the liquid level of the sewage tank,
The sewage filling the chamber and the discharge pipe is boiled and sterilized by the heat of the high temperature chamber.

Then, the sewage in the discharge pipe is pressed out to the separation device by the vapor pressure in the high temperature chamber, and when the steam is released, the sewage flows from the sewage tank and returns to the discharge pipe to a level equal to the level of the sewage tank. The sewage is filled, and while repeating this, the sewage is continuously heated and sterilized and sent to the solid-liquid separation tank. In the solid-liquid separation tank, solid-liquid separation is performed by deodorizing and filtering wastewater with, for example, charcoal, and the filtered water is stored in a water purification tank and circulated for use as toilet flushing water. It can be used as fertilizer as it is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on embodiments shown in the drawings. FIG. 1 is a flow sheet showing an example of a sewage treatment apparatus according to the present invention, and FIG. 2 is a flow sheet showing an example of another sewage treatment apparatus according to the present invention.

[0011] In the figure, numeral 1 indicates that after heating and sterilizing the manure flowed together with the washing water from the toilet 2, the solid component and the water are separated, and the separated water is circulated and used as the washing water for the toilet 2. A wastewater tank 3 for storing manure and washing water, a high-temperature chamber 5 for boiling and sterilizing manure and water flowing from the wastewater tank 3 through an inflow pipe 4, A solid-liquid separation tank 7 for separating sterilized manure and water discharged from the chamber 5 via a discharge pipe 6 and a water purification tank 8 for storing the separated water are provided.

The high-temperature chamber 5 is made of, for example, a metal such as stainless steel or titanium having excellent thermal conductivity and excellent corrosion resistance, and a heater 9 for heating the inside of the chamber 5 to a temperature higher than the boiling point of sewage is provided on the bottom surface. And the bottom area thereof is selected to be about half the area of the heater 9. The high-temperature chamber 5 and the heater 9 are covered with a heat insulating material 10 so that the heat does not leak outside.
A heat conductive material 1 that stores heat of the heater 9 and transfers it to the side surface and the ceiling surface of the high temperature chamber 5
1 is filled.

The high-temperature chamber 5 is provided integrally with, for example, the bottom of the sewage tank 3. The upper end of the inflow pipe 4 for taking in sewage from the sewage tank 3 is opened into the sewage tank 3, and the lower end is connected to the high-temperature chamber 5. It is open near the bottom surface inside. Therefore, the high-temperature chamber 5 is always located at a level lower than the liquid level of the sewage tank 3, and sewage flows into the high-temperature chamber 5 from the sewage tank 3 via the inflow pipe 4 due to the difference in water level. No need.

The discharge pipe 6 for feeding sewage to the solid-liquid separation tank 7 has one end connected to the ceiling of the high-temperature chamber 5 and opened, and the other end connected to the solid-liquid separation tank 7. .
The solid-liquid separation tank 7 is installed on the sewage tank 3 so as to be higher than the liquid level position of the sewage tank 3, and is separated from the upper tank 7 a and the lower tank 7 b each having a charcoal filtration layer formed thereon. Become
The sewage fed through the discharge pipe 6 is injected from above the solid-liquid separation tank 7. The water filtered and deodorized by the filtration layers of the upper tank 7a and the lower tank 7b is stored in the water purification tank 8 via the water purification pipe 12, and is circulated and used as washing water for the toilet 2.

The above is an example of the configuration of the present invention, and its operation will be described below. First, the excrement flushed from the toilet 2 is dropped into the sewage tank 3 together with the washing water,
At this time, since the high temperature chamber 5 is formed below the sewage tank 3, the sewage such as manure and water stored in the sewage tank 3 flows into the high temperature chamber 5 via the inflow pipe 4 by its own weight. Therefore, there is no need to use a pump or the like when the sewage flows into the high temperature chamber 5. Since the discharge pipe 6 is connected to the ceiling of the high-temperature chamber 5, the sewage flows into the discharge pipe 6 up to the liquid level of the sewage tank 3.

Next, when the heater 9 of the high temperature chamber 5 is turned on, the sewage in the chamber 5 is heated and sterilized.
The sewage in the discharge pipe 6 is heated and sterilized by convection with the cold sewage in the discharge pipe 6, and the sewage in the chamber 5 boils, and the sewage filling the discharge pipe 6 is pushed up by the vapor pressure. Is supplied to the solid-liquid separation tank 7 through the discharge pipe 6.

When the sewage in the discharge pipe 6 is fed to the solid-liquid separation tank 7, the steam in the high-temperature chamber 5 escapes and the pressure in the high-temperature chamber 5 decreases. Sewage flows into the sewage tank, and the discharge pipe 6 is again filled with sewage to a height equal to the liquid level of the sewage tank 3.

As described above, the sewage flows from the sewage tank 3 to the solid-liquid separation tank 7 via the high-temperature chamber 5 due to the pressure of the sewage flowing into the high-temperature chamber 5 from the sewage tank 3 and the pressure in the high-temperature chamber 5. The power is supplied, and no power such as a pump is required. In addition, since a part of the steam generated in the high temperature chamber 5 flows backward through the inflow pipe 4 and is blown into the sewage tank 3, the upper end opening of the inflow pipe 4 may be clogged in the sewage tank 3. Absent.

In the solid-liquid separation tank 7, the solid-liquid separation and deodorization by the charcoal filtration layers formed in the upper tank 7 a and the lower tank 7 b and the deodorized water are passed through the water purification pipe 12. It is stored in the water purification tank 8. Since this purified water is heat-sterilized and has no odor, it can be used sufficiently as flush water for flush toilets. Therefore, by circulating a small amount of water, flush toilets can be installed even in places without water resources. . Further, since the solid content remaining in the solid-liquid separation tank 7 is also heat-sterilized, it can be used as it is as an organic fertilizer when it has accumulated to some extent, and no pathogens or the like are generated.

In the above embodiment, the case where the high temperature chamber 5 is installed integrally with the bottom of the sewage tank 3 has been described. However, it is needless to say that the high temperature chamber 5 may be installed separately from the sewage tank 3. .

FIG. 2 is a flow sheet showing another manure processing apparatus according to the present invention. In addition, the same reference numerals are given to portions common to FIG. 1 and detailed description is omitted.
In this example, the high-temperature chamber 5 that generates steam by boiling the water flowing through the inflow pipe 21 from the water purification tank 8 that stores the purified water used as the wash water for the toilet 2, and the high-temperature chamber 5 that is generated in the high-temperature chamber 5 The steam is blown out into the sewage tank 3 to agitate and heat-sterilize the manure stored in the sewage tank 3, and the manure and water sucked up from the sewage tank 3 via a vacuum pipe 23. The apparatus includes a solid-liquid separation tank 7 to be separated, and a water purification pipe 12 for feeding the separated water to the water purification tank 8.

The high temperature chamber 5 is installed at a position lower than the liquid level of the water purification tank 8, and the solid-liquid separation tank 7 is installed at a position higher than the liquid levels of the sewage tank 3 and the water purification tank 8. Further, the inflow pipe 21 is connected to the high-temperature chamber 5.
The steam pipe 22 is connected so as to open near the bottom of the inside thereof, and one end of the steam pipe 22 is connected to the ceiling of the high-temperature chamber 5 while the other end of the steam pipe 22 passes through a position higher than the liquid level of the clean water tank 8. The pipe is opened so as to open below the liquid level of the sewage tank 3. Reference numeral 24 denotes a float that keeps the distal end openings of the steam pipe 22 and the vacuum pipe 23 at a position that is sunk a certain depth from the liquid level of the sewage tank 3.

According to this, since the high temperature chamber 5 is installed at a position lower than the liquid level of the water purification tank 8, the purified water in the water purification tank 8 is supplied into the high temperature chamber 5 due to the difference in water level. When the heater 9 of the high temperature chamber 5 is turned on, the purified water in the chamber 5 is heated and boiled, and the steam is continuously supplied to the sewage tank 3 via the steam pipe 22. Since the tip is always attached to the float 24 and is always below the liquid level of the sewage tank 3, steam is blown out into the sewage to agitate the sewage and simultaneously sterilize by heating.

When the entire sewage tank 3 has been heated to some extent, the sewage is fed to the solid-liquid separation tank 7 through the vacuum pipe 23, and the water separated in the solid-liquid separation tank 7 is purified. The water is stored in the purified water tank 8 through the filter 12. By doing so, not only can the water in the water purification tank 8 be circulated and used for the toilet 2, but also the separated solid components are sterilized and can be used as they are as organic fertilizers. A flush toilet can be installed in places where a vacuum car is not allowed.

[0025]

As described above, according to the present invention, a large amount of sewage including manure can be heated with a very simple structure without using a stirrer or a large-capacity heater and with a small amount of energy. It can be sterilized to the extent that it can be used as it is as an organic fertilizer, and the flush toilet can be used even in places where water resources are scarce and the collection of manure by vacuum car is not performed by circulating the toilet wash water. It has an excellent effect that it can be installed.
