Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>

FIG. 1 shows and describes a configuration of a water treatment system according to the first embodiment of the present invention.

As shown in the figure, the water treatment system 1 according to the embodiment is a U arranged between a solid / liquid separation tank 2 such as a septic tank, a water tank 3, and the separation tank 2 and the water tank 3. It has character pipes 4 and 5. The separation tank 2 and the pipe 4 are communicated with each other by a connecting pipe 6, the pipe 4 and the pipe 5 are communicated with each other by a connecting pipe 7, and the pipe 5 and the water tank 3 are communicated with each other. It communicates with the connecting pipe 8. A valve 9 is provided on the connecting pipe 6, and a valve 10 is provided on the connecting pipe 7. The water tank 3 is connected to a pump 11 such as an electric pump or a manual pump, and the purified water pumped from the water tank 3 by the pump 11 is connected by a pipe (not shown) so as to be guided to the toilet tank 12. ing. The flow path device is composed of pipes 4 and 5 and connecting pipes 6, 7 and 8.

In such a configuration, the water level L1 of the separation tank 2 is common on the same line up to the pipes 4, 5, the connecting pipes 6, 7, 8 and the water tank 3. In other words, the separation tank 2, the water tank 3, the pipes 4, 5, and the connection pipes 6, 7, and 8 have the same height from the installation surface X so that their horizontal levels L1 are at the same level. Are arranged on the same line.

Therefore, when the water level of the separation tank 2 rises from L1 to L2 due to the drainage from the toilet 13, when the water level of the water tank 3 is lower than L1, the water level level discharges water to the water tank 3 while discharging water to the water tank 3. It goes down to the water level L1. No energy is required for this movement of wastewater. The pipe 4 that passes through the U-shaped pipes 4 and 5 while the drainage moves, utilizing the natural function of keeping the water level of the separation tank 2 at L1. , 5, Adjust the size, flow rate, and flow velocity of connecting pipes 6, 7, and 8.

In the U-shaped pipes 4 and 5 through which the wastewater passes, for example, a filter can be conceptually included or a treatment device can be installed. To give an example, if a screen or gravel, sand, etc. that play an equivalent role is placed at the bottom of the U-shaped pipes 4 and 5, a fluid filter (granular activated carbon, etc. can be put in) can be used. Suppresses the outflow of granules, powder, etc.

If the final part of the U-shaped pipes 4 and 5 is below the level (height) for accepting water, further treatment such as permeation type filter treatment can be performed. The flow path formed by the U-shaped pipes 4 and 5 can be expanded, and the wastewater treated in the flow path can be discharged to the toilet above the distribution tank 2 by a pump 11 such as a manual pump. If it is pumped up in the tank 12, a water circulation process that does not require mechanical energy can be realized.

Here, FIGS. 2 (a) to 2 (c) show an example of the cross-sectional shape of the U-shaped pipes 4 and 5. What is the cross-sectional shape of the pipes 4 and 5, such as a hexagon as shown in FIG. 2 (a), a quadrangle as shown in FIG. 2 (b), and a circle as shown in FIG. 2 (c). It may be a shape, and as shown in FIG. 3, the shape may change in a pair. Further, a pair having different shapes, sizes and the like may be configured to be connected to each other.

<Second Embodiment>

FIG. 4 shows and describes the configuration of the water treatment system according to the second embodiment of the present invention. Here, the explanation will proceed assuming that the source of wastewater is a toilet.

As shown in the figure, the water treatment system 21 according to the present embodiment includes a tank 22 (first tank) which is a separation tank such as a raw water tank and a septic tank, and a tank 23 (second layer) for storing treated water. And a plurality of stages of U-shaped pipes 24, 25, 26 provided between the tank 22 and the tank 23. In the following description, the flow path by the pipe 24 is referred to as a first flow path, the flow path by the pipe 25 is referred to as a second flow path, and the flow path by the pipe 26 is referred to as a third flow path.

The tank 22 has a space above the discharge port A for storing the liquid, and the tank 23 has a space above the inflow port G for storing the liquid, and the discharge port A and the drain port have a space above the discharge port A. U-shaped pipes 24 to 26 are arranged in a plurality of stages in the flow path between the G and the pipe. Therefore, after performing some kind of primary treatment such as separation of individual liquids in the tank 22, the drainage is discharged from the discharge port A after passing through the first to third flow paths by the pipes 24 to 26. It will flow from the discharge port G to the tank 232.

Discharge port A of the tank 22, inflow port B to the first flow path, discharge port C from the first flow path to the second flow path, inflow port D to the second flow path, second flow The discharge port E from the road to the third flow path, the inflow port F to the third flow path, and the discharge port G from the third flow path to the tank 23 are on the same line above the water level level L1. Preferably, it provides a space for drainage that fills between the water level L1 and the water level L2. In other words, the tanks 22, 23, the pipes 24 to 26, and the connecting pipes 60 to 63 are arranged on the same line in the horizontal direction so that the heights from the installation surface X on the bottom surface are the same. Of course, there are no restrictions on the shape, distance, number, or combination of the first to third flow paths. It is also possible to install another flow path from the inflow port A to the discharge port G for drawing out the liquid from the middle.

When the discharge port A, the inflow port B, the discharge port C, the inflow port D, the discharge port E, the inflow port F, and the discharge port G are on the same line, the water level of the tank 22 increases due to the inflow of drainage from the toilet or the like. Even if it rises, it flows out from the discharge port G to the tank 23 until it drops to the water level L1, and can be flushed to the full water level of the tank 23. At that time, no energy is required to move water. There is no limit to the distance between each inlet and outlet. Therefore, it is possible to freely carry out the moving distance of the liquid and the processing for the liquid performed between them.

The discharge port A of the tank 22 and the inflow port B of the pipe 24 are communicated by the connecting pipe 60, the discharge port C of the pipe 24 and the inflow port D of the pipe 25 are communicated by the connecting pipe 61, and the discharge port E of the pipe 25 and the pipe. The inflow port F of the 26 is communicated with the connecting pipe 62, and the discharge port G of the pipe 26 is connected to the tank 23 by the connecting pipe 63. These connecting pipes 60 to 63 are also arranged on the same line above the water level level L1.

Valves 27, 28, 29 are provided on the connecting pipes 60, 61, 62. By providing the valves 27, 28, and 29 between the flow paths in this way, the moving speed and amount of the liquid can be controlled. For example, when the full water sensor 39f detects full water and an overflow is predicted, at least one of the valves 27, 28, and 29 can be opened to discharge the treated water. At the same time, it is possible to control the inflow of liquid, such as stopping the inflow, and control the inside of the flow path. Not only the full water sensor 39f, but also the information from each sensor 39a to 39e, from the discharge port A to the discharge port G. The processing in the flow path can be controlled.

When the tank 22 is not used, the inflow can be restricted and controlled by the valve 27 by the inflow valve 31. Further, the discharge port G can be used as an inflow port when the tank 23 is used, and as a drainage port in other cases. That is, the discharge port G plays a role as an outlet for the fluid.

The types of sensors 39a to 39f include those capable of measuring not only the quality of the liquid but also the flow rate, water level, temperature, etc., and the clogging of the filter medium can be grasped and predicted by the flow rate, water level, and the like. The installation location of the sensors 39a to 39f is not particularly limited and can be freely designed. The control device 70 can electronically control the machines, valves 27 to 30, and the like connected to the flow path based on the sensor data of the sensors 39a to 30f.

Hereinafter, the configuration of the first to third flow paths will be described in more detail.

(First flow path)

The first flow path is composed of a U-shaped pipe 24 arranged between the inflow port B and the discharge port C. The liquid flowing in from the inflow port B flows downward in the direction of the filter medium 44, then flows upward toward the discharge port C, and moves from the discharge port C to the inflow port D via the connecting pipe 61. .. By utilizing this movement of the liquid, it becomes possible to perform various treatments on the liquid. The process does not require power to move the liquid.

The pipe 24 is provided with an intake / exhaust valve 37b, an air filter 38b, and a motor 59. Aeration treatment, agitation treatment, or the like can be applied to the liquid flowing downward from the inflow port B and the liquid flowing upward from the bottom toward the discharge port C. Substances that can be treated with some effect by contacting with a solid or fluid for stirring, such as granular activated carbon or ion exchange resin, can be added. As for aeration, a gas effective for liquid treatment such as ozone aeration can be freely used.

By inserting an adsorbent or a filter material between the inflow port B and the filter material 44, stirring and aerating the sewage, effects such as sterilization and decolorization can be obtained by adsorbing, filtering and ozone aeration for sewage treatment. The processing method can be appropriately selected and changed by necessary means. It can be used not only for purification purposes but also for the purpose of adding necessary components. PH adjustment, aggregation treatment, sugaring, etc. are also possible. Since the intake / exhaust valve 37b is installed in the pipe 24 and the air filter 38b is installed to prevent foreign matter, water, germs, viruses, etc. from entering the intake / exhaust, the inside of the flow path is not contaminated. The same applies to each tank and flow path, and the inside of the tank and flow path is not contaminated.

The first flow path can be replaced in units of the first flow path by disconnecting the connection at the inflow port B and the discharge port C and providing a mechanism that allows free restoration. An additive insertion valve 33, an aeration inlet valve 34, an internal sediment discharge valve 35, and the like are arranged in the piping portion leading to the filter material 44.

Regarding the filter media 41, 42, 43, 44, when the materials necessary for water treatment such as activated carbon, stone, sand, ion exchange resin, adsorbent, etc. are spread or put in a container, ventilation and water permeability are all right. For example, it can be used without limitation on the size and type of material. The following can be considered as a method for fixing the filter media 41, 42, 43, 44.

That is, first, it can be fixed by filling a water-permeable, breathable mesh-like bag, or a container that fits in the flow path with a filter medium. Secondly, each filter medium can be fixed by stacking them as they are. Thirdly, the filter material 44 divides the space so as to divide the flow path, but if it has a heavier specific gravity than a liquid such as stone and can maintain water flow and air permeability in the gap even if it is deposited. , Can double as a filter material and a partition. Fourth, a screen having filtration and foreign matter removal functions is fixed and incorporated in the flow path itself without any limitation. It can also be used to control the movement of the filter media.

When the filter material 44 is arranged at the bottom of the U-shaped pipe 24 and is separated by a filter material or the like across both of the rising portions, the inflow port B and the discharge port C are different on each side. Aeration treatment becomes possible. In addition, aeration and filtration can be performed simultaneously between the inflow port B and the outlet C. In the filtration process, any filter material may be selected as long as it has water permeability and air permeability.

When aeration is simultaneously used for the liquid flowing upward while using the adsorbent and the filter material, the outflow of the adsorbent and the filter material can be prevented by providing the screen 57 in front of the discharge port C. That is, when aeration and an adsorbent are used in combination, or when some solid is added by stirring to treat the liquid, the flow path can be blocked by a screen 57 or the like to prevent the outflow of the additive. At that time, it is possible to separate the range of treatment, the type of treatment, and the additives. The screen 57 may be water permeable and breathable, and its density is not limited. The screen 57 having filtration, foreign matter removal, and filling movement control functions can be installed inside the pipe 24 as much as necessary at the required place regardless of the fixing method such as welding, adhesion, sandwiching, and integral formation. Is.

When, for example, a circular pipe 24 is used for the first flow path, a flow velocity is changed by attaching an object having a smaller diameter such as an orifice 58 in the middle of the first flow path and changing the diameter of the flow path. It is also possible to change.

In addition to the above, if a reverse cleaning valve and a drain valve for cleaning the clogging of the filter medium 4 are provided between the inflow port B and the discharge port C, the reverse cleaning and drainage can be performed between the inflow port B and the discharge port C. You can also do it between. Any number of valves and the like can be installed anywhere between BCs according to the required purpose and treatment. There are no restrictions on applications such as aeration gas inlet and sediment discharge.

(Second flow path)

The second flow path is configured by providing a U-shaped pipe 25 between the inflow port D and the discharge port E. By closing the valve 28 and the valve 29, and further closing the valves 45, 46, and 47, the movement of the liquid in the flow path can be controlled to be small, so that the liquid can be mounted on the object to be transferred.

In the second flow path, a replacement unit 49 or the like is arranged between the valve 45 and the valve 46, a UV sterilizer 50 or the like is arranged between the valve 46 and the valve 47, and the valve 47 and the discharge port E are connected to each other. An ion exchanger 51 and the like are arranged between them. In the second flow path, valves 28 and 29 are provided at the inlet and outlet, and valves 45 to 47 are provided at the inlet and outlet of each region. And can be added freely. As described above, in each region in the middle of the second flow path, a processing device such as the above-mentioned UV sterilizer or ion exchanger can be inserted as needed, and the type and number thereof are not limited. ..

(Third flow path)

The third flow path is configured by providing a U-shaped pipe 26 between the inflow port F and the discharge port G. An electrode and an electrolyzer 52 are arranged in the piping portion from the inflow port F to the valve 48, and a heater or a cooler 53 is arranged below the valve 48. Electrical insulation and temperature insulation can be performed on the flow path itself or for each replacement unit. The piping portion on the downstream side of the heater or cooler 53 has spaces 54, 55, 56 separated by screens 40a to 40d.

In this way, in the third flow path, the inside of the flow path can be partitioned by screens 40a to 40d or the like. The screens 40a to 40d may be movable or fixed. The screens 40a to 40d need only have water permeability and breathability, and a suitable material and shape can be selected. Further, in the flow path and in the spaces 54, 55, and 56 separated by the screens 40a to 40d, as a processing device, one for the purpose of filtration, one for the purpose of adsorption filtration by contact with a liquid, and one that dissolves out. It is possible to individually install and fill those intended for the desired purification treatment, such as those intended for addition, those having a complicated flow path for mixing the added substances, and the like.

For example, in at least a part of the spaces 54, 55, 56 of the pipe 26 of the third flow path, for the purpose of a porous medium such as sponge, glassy material, activated carbon, natural stone, soil, etc. for the purpose of biological treatment. By adding the material, it is possible to purify the wastewater. Further, anaerobic, aerobic microorganisms, anaerobic aeration, and aerobic aeration can all be arbitrarily installed in the spaces 54, 55, and 56. Further, by combining with a stirring device or the like connected to a driving device such as an aeration or a motor, it is possible to perform biological treatment while stirring.

A valve 30 bypasses between the second flow path and the third flow path, the fluid is sensed by the sensor 39d arranged in front of the valve 47, and the valves 47 and 48 are closed as necessary. , It is possible to bypass by opening the valve 30. Here, as an example, the bypass is performed between the second and third flow paths, but the bypass destination beyond the second flow path can be freely designed, installed, and expanded. The destination of the fluid can also be freely designed.

It can be freely incorporated under insulation, and these various devices can be partially replaced or expanded.

Further, the flow path itself formed by the piping can be regarded as one container of the filter material, and in that case, the screen for the purpose of filtering, the purpose of fixing the filling, the purpose of stirring the liquid, etc., which are directly required for the flow path itself, can be regarded. It can be fixed by welding, adhesive sandwiching, etc.
