Description

[Detailed description of the invention] This invention relates to a sprinkler hearth type water treatment device that utilizes the photosynthetic action of photosynthetic bacteria such as chlorella or green algae such as water hyacinth.Moreover, it uses sunlight as a light source to the maximum extent possible. This invention relates to a multistage sprinkler hearth type water treatment device to be used.

(Prior Art) Conventionally, water treatment devices that utilize photosynthesis are publicly known (for example, Japanese Patent Application Laid-Open No. 52-38777, Japanese Patent Application Laid-open No. 53-1987)
108656).

Additionally, a water treatment device that transports sunlight as a necessary light source to promote photosynthesis is also publicly known (Japanese Patent Laid-Open No. 52-387
(as described in Publication No. 77).

However, there is still no precedent for a multi-stage sprinkler hearth type water treatment device with large water treatment capacity and high precision that effectively utilizes sunlight to promote photosynthesis for water treatment.

(Purpose of the invention) Therefore, the purpose of this invention is to provide a multi-stage watering hearth type water treatment device for water treatment using photosynthesis, which effectively transports and utilizes sunlight using optical fibers as a light source. There is a particular thing.

In order to achieve the above purpose, the sprinkler hearth type water treatment device of this invention has a watering furnace primordium installed above the water tank, and water is pumped up by a circulation pump. The water to be treated is sprayed from the upper end of the watering P primordium through a watering pipe.

The sprinkler furnace primordium is made by placing granular furnace materials with a substantially uniform layer thickness on shelves provided in multiple stages at predetermined intervals in the vertical direction, and placing rod-shaped furnace materials at a position above each stage of furnace materials. The light emitters are installed approximately horizontally, and a downward reflecting plate is installed above each light emitter.

On the other hand, each light emitting body is connected to a sunlight condensing plate through an optical fiber.

(Effect) In other words, the light necessary for photosynthesis is evenly applied to the furnace materials in each stage by the diffused light emission through each light emitter, and photosynthesis is promoted.

Therefore, the water to be treated that is sprayed from the upper end of the water swamp primordium through the water sprinkler pipe increases its degree of purification each time it passes through the furnace materials at each stage and descends.

Therefore, it is permissible to sprinkle a considerable amount of water to be treated, and the water to be treated is evenly purified.
In other words, high processing capacity and highly accurate water treatment can be expected.

In addition, although water treatment uses photosynthesis, BO
Since it is excellent in removing not only D and SS but also nutrient salts such as nitrogen, it can be widely applied to water treatment in all fields.

Furthermore, although it uses sunlight as a light source, it contributes to resource and energy conservation, and there are no maintenance problems.

Furthermore, since sunlight is effectively transported and utilized using light condensing plates and optical fibers, this sprinkler hearth type water treatment equipment can be installed and used, for example, in basements where sunlight does not directly shine. It has excellent flexibility in terms of where it can be used, and a large degree of freedom in equipment design.

Furthermore, this sprinkler hearth type water treatment equipment has furnace materials stacked vertically in multiple stages to form the sprinkler furnace primordium, so it occupies a relatively small space compared to the water treatment capacity and amount of furnace materials. It has the advantage of being able to be installed and used even in narrow spaces.

(Example) Next, the illustrated embodiment will be explained.

FIG. 1 shows a sprinkler-type water treatment device according to this invention.

In the figure, 1 is a raw water tank, 2 is a circulating water tank, 3 is a settling tank, and 4 is a watering furnace primordium installed above the circulating water tank 2.

The structure of the water reactor primordium 4 is, as shown partially enlarged in Fig. 2, in a vertically cylindrical watertight casing 4a, stainless steel mesh casings are placed at appropriate intervals in the vertical direction. A required number of shelves 5 are installed substantially horizontally, and granular furnace material 6 is placed on each shelf 5 in a substantially uniform layer thickness.

However, between the upper shelf 5 and the lower furnace material 6, an appropriate gap S is formed so that the light emitting body described below is installed and the light diffused and emitted through the light emitting body evenly irradiates the furnace material 6. It is composed of

In the figure, numeral 7 is a rod-shaped light emitting body installed substantially horizontally above the furnace materials 6 in each stage to provide the necessary light evenly.

The light emitter 7 has a length sufficient to cross the casing 4a (FIG. 1).

In the figure, reference numeral 8 indicates a reflecting plate installed below the shelves 5 in each stage as a downward concave mirror.

That is, each of the light emitting bodies 7 is placed directly below each of the reflecting plates 8 at a so-called focal position.

Each light emitting body 7 has a casing 4a as shown in FIG.
It is installed so that it can be pulled out.

That is, the backing 9 that is in close contact with the light emitter 7 is connected to the backing press 10 and the backing press 10 to the light emitter mounting seat 12.
It is strongly pressurized by the poles H1 and 11 that are fixed to it, and is configured to exhibit a water-sealing effect.

The light emitter 7 can be pulled out by loosening and removing the port I.11.

In the figure, reference numeral 13 denotes a sunlight condensing plate (light collector), which is connected to each of the above-mentioned light emitters 7 through optical fibers 14.

That is, the sunlight collected by the light condensing plate 13 is effectively transported through the optical fiber 14, and diffused and emitted light evenly onto the furnace material 6 through each light emitting body 7 in the multistage watering furnace primordium 4, thereby causing photosynthesis. It provides the necessary light and promotes photosynthesis.

In the figure, 15 is a raw water pipe that leads raw water to the raw water tank 1, 16 is a raw water pump that supplies the raw water in the raw water tank 1 to the circulating water tank 2 through the supply pipe 17, and 18 is the water sprinkling water in the circulating water tank 2 through the water sprinkling pipe 19. a circulation pump for sprinkling water on the upper end of the reactor primordium 4;
21, the water overflowing into the overflow groove 2a of the circulating water tank 2 is transferred to the sedimentation tank 3.
A communication pipe 2o leading to the overflow groove 3a of the settling tank 3 is a conduit leading to the treated water that has overflowed into the overflow groove 3a of the settling tank 3.

Since it has the above-mentioned configuration, this sprinkler side floor type water treatment device has the following features:
Not only can it be installed and used outdoors where it is directly exposed to sunlight, but it can also be installed and used indoors, particularly in basements, where it is not exposed to sunlight at all.

That is, it is necessary and sufficient that the light collecting plate 13 is installed at a high position suitable for collecting outdoor sunlight (a position not in the shade), preferably as a solar tracking type.

In this way, the sunlight collected by the light condensing plate 13 is irradiated onto the furnace material 6 of each stage in the sprinkler stream primordium 4 in a sufficient amount as light necessary for photosynthesis, so the circulation pump When the water in the circulation tank 2 is sprinkled and circulated through the water sprinkling pipe 19 by 18, the photosynthesis of photosynthetic bacteria such as chlorella or green algae such as water hyacinth cultivated on the surface of the saido material 6 of each stage is sufficiently promoted. It has a purifying effect on sewage and wastewater.

The inside of the watering stream primordium 4 is divided by multi-stage furnace materials 6, and
Since it has a configuration that receives and admits sunlight over a large area, it has high water treatment capacity and water treatment accuracy.

On the other hand, the light emitters 7 are installed under the reflector plate 8, and water does not come into direct contact with the light emitters 7, which has the effect of preventing the generation of slime.
