Means for solving the problems: The excrement inflow portion, which is located at approximately the center of the decomposition tank, is surrounded by a cylinder, and a rotating shaft that is rotated by a motor is provided on the center axis of the cylinder, and the rotating shaft is made of stainless steel or the like. A number of thin round rods are attached to the rotating shaft to form a crushing rod, and the cylinder is composed of two cylinders of different diameters that form a circular core. The inner cylinder has an upper end above the water level and a lower end above the bottom. The upper end of the outer cylinder is located below the water level and the lower end is in contact with or slightly above the bottom,
An air diffuser that blows air from the bottom side is disposed in the decomposition tank.

[0003] In particular, a round bar mounted at a right angle to a rotating shaft is easy to remove even when an undispersed material such as cloth is caught by a round bar made of stainless steel and having a smooth surface of 2 to 5 mm, and excrement is excreted. , Paper and the like can be crushed and dispersed. The round bar may be made of steel or the like that is difficult to be bent, and the surface may be smoothed by chrome plating or the like. When rotating in one direction, the round bar may be bent like the leading edge of the screw propeller.

[0004] The inner cylinder and the outer cylinder disposed in the disassembling tank are made of concentric nets having different diameters or a perforated plate perforated on the entire surface, and the inner cylinder and the outer cylinder are formed of two different diameters. It is preferable that the inner cylinder is formed between two cylinders so that the inner cylinder can be filled with particulate matter such as microbial growth material and the outer cylinder can be filled with a porous stone or the like. The mesh or perforated plate is made of metal. A good corrosion-resistant product made of stainless steel or the like may be used. A plastic net may be attached to the frame instead of the wire net to form a cylindrical shape, and a perforated plate or a plastic plate may be used.

In addition, a sedimentation tank, a filtration tank, an adsorption tank, a purified water storage tank, an evaporation tank, and the like are sequentially connected to the outside of the outer wall of the decomposition tank along the outer wall. The effect of keeping the tank warm by shutting off the tank from outside air can be expected. An air pump for air supply, a water circulation pump chamber, etc. may also be provided along the outer wall of the decomposition tank with a partition wall provided, and an air pump may be provided with an air heating device to heat the air supply, It is preferable to attach a heater or the like to the tank so that the temperature of the decomposition tank can be maintained at 20 ° C. or higher. The disassembly tank and the like can be made of a metal plate or molded with plastics, and in cold regions, etc., it is acceptable to use a composite material having a heat insulating effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. As shown in FIGS.
In the center of the decomposition tank (2), a net made of metal or synthetic resin or a cylinder of two diameters consisting of a perforated plate perforated on the entire surface is used. The upper end of the outer cylinder (12) is separated from the decomposition tank (2) and the water level when filled with water. The inner cylinder (11) and the outer cylinder (12) are arranged below the water level so that they are concentric.

A rotating shaft (13), which is rotated by a motor (15), is provided on the center shaft of the inner cylinder (11), and the rotating shaft (13) is made of stainless steel or chrome-plated steel having a smooth surface. A plurality of round rods of 2 to 5 mm are attached at right angles to the rotating shaft (13) to form crushing rods (14), and at least the inside of the outer cylinder (12) provided in the decomposition tank (2). A diffuser pipe (15) for blowing air from the bottom side is provided in the inner cylinder (11). Although the motor (15) for rotating the rotating shaft (13) of the crushing rod (14) is shown to be provided below the bottom plate of the decomposition tank (2), it is provided on the bottom surface in the tank or on the lid side of the tank. There is no problem if the rotation is reversed in one direction or every constant rotation, and the air diffuser (15) may be connected to the outside of the outer cylinder (12) of the decomposition tank (2).

[0008] The inner cylinder (11) and the outer cylinder (12) are assembled by a cylinder made of a mesh or a perforated plate having different concentric diameters, respectively.
The gap between the net and the net or the perforated plate and the perforated plate is about 15 mm, and the inner cylinder (11) is filled with particulate matter such as a microorganism growth material,
The outer cylinder (12) can be filled with a porous stone or the like. Therefore, the bottom surface of the inner cylinder (11) and the outer cylinder (12) is provided with an annular net or a perforated plate as a bottom plate to prevent the filler from falling off.

Sedimentation tanks (3) and (4), outside the outer wall of the decomposition tank (2), for setting solid components in the treated liquid treated in the decomposition tank (2) along the outer wall; Filtration tank (5) filled with gravel and the like for filtering suspended matter, further adsorption tanks (6) and (7) filled with activated carbon and charcoal for absorbing dissolved matter, etc., storage tank (8) for storing purified water (9), etc. are connected and arranged so as to surround the decomposition tank (2). The packing is filled as shown in the adsorption tank (6) in FIG. Further, an evaporating tank or the like for evaporating excess purified water may be provided continuously as required.

In FIGS. 1 and 2, a machine room (10) provided with an air inlet pump, a water pump, and the like is provided outside the outer wall of a part thereof so as to surround the decomposition tank (2). The outer wall of (2) is configured not to be in direct contact with the outside air.

[0011]

As described above, the toilet water circulation type westernization apparatus of the present invention is constructed as described above. When manure and toilet paper flow into the inner cylinder from above, the solid is crushed by the rotating crushing rod. The mixture is agitated by air blown out from a lower diffuser tube, comes into contact with a microorganism-growing material, and is decomposed by microorganisms. In particular, since the inner cylinder and the outer cylinder are composed of a net or a perforated plate, urine and crushed and dispersed feces partially pass through the inner cylinder and the outer cylinder, and good contact with the microorganism-proliferating material and the like, resulting in good decomposition. Become.

Since the crushing rod is a round rod made of steel or the like having a smooth surface, even if solids, especially fibers such as toilet paper, are entangled, they are easily separated by centrifugal force, dispersed into single fibers, and foreign matter such as cloth is entangled. But it can be easily removed.
Further, since a settling tank or the like for the treatment liquid is provided so as to surround the decomposition tank, the decomposition tank can be kept warm without directly receiving the temperature of the outside air.
