Description

[Detailed description of the invention] The present invention relates to a urine/urine water treatment device that purifies urine/urine water including a small amount of washing water directly sent from a toilet tank or toilet bowl, and discharges the purified water underground. It is characterized by being able to evaporate the entire amount without evaporation and having a simple structure.

An example of implementation of the present invention will be described in detail below based on the drawings.

The device A is composed of a tank 1 that purifies the urine and urine water a, and an evaporator 5 that evaporates the purified water, and the tank 1 is made of a well-known material such as FRP or other synthetic resin, and is a popular type or water-saving type. In addition, a flush toilet γ, such as a water-saving type, which is even more water-saving than the water-saving type, is connected via the communication pipe 8.

The inside of this tank 1 is divided by a partition wall 2 into an upper section A and a lower section B, and both sections AB communicate through communication holes 3 formed in a part of the partition wall 2.

The lower compartment B is provided with an inflow chamber A for urine and water a that communicates with the toilet bowl 7 through the communication pipe 8 at a lower level, that is, at the bottom of the tank, and a gravel layer 9 at a higher level. Urine water a is formed so that it can permeate into the gravel layer 9 by capillary force and rise into the upper compartment A from the communication hole 3, and the sludge a1 to be separated by sedimentation in the same chamber 3 can be pumped out from the pumping port 10. to form.

The upper section A communicates via the gravel layer 11 with the gravel layer 11 located on the side of the communication hole 3 and the blower pipe 14 located at the bottom of this gravel layer 11 to supply air to the same layer and grow it in an aerobic state. It is composed of a soil layer G and a water collection pipe 4 provided at a lower level of the soil layer G, that is, at the bottom of the partition wall 2, and a communication hole 3 from the lower section B.
The urine and urine water a rising through the capillary permeation from the gravel layer 11 into the soil layer G is purified in the rising process, and then the purified water moves capillary to a lower level and falls to the water collection pipe 4. The liquid flows into the evaporator 5.

More specifically, the tank 1 is formed into an elongated shape with an appropriate medium and depth that satisfies both the soil storage capacity corresponding to the required purification capacity and the filth storage amount, and the tank 1 is formed into an elongated shape with an appropriate medium and depth. 2, the wall portion 2a in which the communication hole 3 is opened is sloped to increase the amount of urine and water that permeates between the gravel layers 9 and 11 facing the limited horizontal direction, and also to increase the amount of urine and water that permeates into the limited horizontal tank The horizontal area of the soil layer G between the wall 2a and the water collection pipe 4 is expanded to the maximum extent possible, thereby expanding the purification area where aerobic microorganisms can actively grow and inhabit. Barrier 2b with a part protruding
is provided so that the urine and water a purified while moving downward through the upper edge 2c of the wall portion 2a is blocked by the barrier 2b and moves upward through the capillary again to be repeatedly purified. This increases the purification ability in the purification area.

Therefore, the number of barriers 2b is not limited to that shown in the drawings, but is preferably increased depending on the scope of the purification area, and the height thereof is preferably gradually lowered from the upper edge 2c of the wall portion 2a toward the water collection pipe 4 side.

It is also optional to carry out the process without providing the barrier 2b.

Furthermore, the partition wall 2 has a structure in which it is suspended from the upper edge of the tank 1, thereby making the installation and assembly easier.

In addition, the gravel layer 9.11 is formed of foamed glass gravel, which has excellent buoyancy, for example, and the gravel floating in the lower section BKj floats on the surface of the urine/water water a even without a support, and is suspended on the surface of the urine water a by its buoyancy. A gravel layer 9 is interposed between the partition wall 2 and the partition wall 2, supporting the partition wall 2 by its buoyancy and communicating with the partition wall 2.

The evaporator 5 is of various types, such as a centrifugal spray type, an ultrasonic type, a steam type, and a hot air type.
Most of the purified water flowing from the water collection pipe 4 through the water collection pipe 4 is vaporized and evaporated from the discharge port 6.

Thereby, the urine and urine water a is led from the storage side, that is, the lower compartment B, through the gravel layer 9 and the communication hole 3, to the purification side, that is, the upper compartment A, over the entire length of the tank, and from the gravel layer 11 to the soil layer G. In the process of permeating through the soil, it is purified to below the legal standard value, and a portion of the purified water rises in the capillaries and evaporates from the surface of the soil layer G, while the remaining majority moves downward in the capillaries and flows through the water collection pipe 4. The sludge a1 that flows into the temporary storage tank 12, is evaporated to the ground from the discharge port 6 by the evaporator 5, and settles in the inlet chamber A can be pumped out from the pumping port 10 at any time.

Similarly, the purified water flowing into the temporary storage tank 12 may be sterilized with a disinfectant or sterilizing solution in the same room.

As described above, the present invention purifies the urine and urine water entering the inflow chamber of the lower compartment in the soil layer of the upper compartment, and some of the purified water is taken from the surface of the soil layer, and the rest is The majority of the capillary gravity movement to the bottom of the upper compartment is not retained in the same compartment, but is collected in the collection pipe and evaporated in the evaporator, allowing the entire volume of purified water to be evaporated. In addition to being able to perform spray treatment, the purified water that has migrated by capillary gravity to the bottom of the soil layer can be immediately discharged to the outside of the tank, and the lower part of the soil layer does not become saturated with the remaining purified water, achieving continuous high-efficiency purification treatment capacity. It is something that can be demonstrated.

The gravel layer that causes the sewage in the inflow chamber to rise capillary from the communication hole to the soil layer in the upper section is a floating layer with a specific gravity that is lighter than water, so after ensuring the specified capillary movement of the sewage, and By supporting the bulkhead from the lower surface by its buoyancy, the structure is strong, and the structure can be simplified by eliminating the need for a support wall of the gravel layer itself, thus achieving the intended purpose.
