Description

[0001]
[Industrial application fields]
Provide a simple planter that allows you to easily grow plants while enjoying the scenery in the aquarium.
[0002]
[Conventional technology]
There have been no examples in the past that have devised a planter having a water purifying action and a plant growth promoting function as seen in the present invention using a filtration layer mainly composed of an ion exchange resin.
[0003]
[Problems to be solved]
This is to provide gardening supplies that are easy to handle for the physically handicapped and the elderly.
[0004]
The apparatus of the present invention comprises a filtration layer A mainly composed of an ion exchange resin installed in a water tank for purifying water and / or a filtration layer B mainly composed of an ion exchange resin installed in a planter and forced passage of air. The water purification apparatus includes a water purifier that includes a flow means (air lift), and the water contained in the filtration layer is forced to flow by air sent from the forced flow means. The device has a water tank and a cultivation device, and the forced air is sent from the filtration layer (A) in the water tank to the filtration layer (B) in the cultivation device, and a part of the circulating water Is supplied to the root of the plant as moist air, and most of the water is returned to the water tank .
[0005]
By breeding ornamental fish in the aquarium, the growth of plants is promoted using ammonium ions and inorganic ions discharged from the rearing organisms as nutrient sources.
[0006]
It has been found that the use of an ion exchange resin not only promotes biofiltration, particularly denitrification, but also works effectively as a supply source of moisture and inorganic components for plants.
[0007]
By heating the water, it became an environmental condition suitable for the growth of tropical foliage plants, and it became possible to cultivate plants that were difficult to winter over unless they were in a greenhouse.
[0008]
[Operation] The filter medium applied to the filtration layers A and B has a certain effect if it has a function of purifying water. However, the most effective filter medium to be used is an ion exchange resin, in particular, a powder ion. An exchange resin is a basic component.
[0009]
This filter medium has not only a chemical adsorption action but also an excellent physical adsorption action, and is excellent in bacteria adsorption, and as a result, exhibits an excellent biological filtration action.
[0010]
As for this filter medium, the present applicant has already made clear in Japanese Patent Application No. 11-376371. However, it is sufficient that the used ion exchange resin is pulverized into fine particles, which means that resources can be recycled. The significance is greater than the point of view.
[0011]
The filtration layer mainly composed of an ion exchange resin in the present invention means that the ion exchange resin as a main component does not necessarily need to be a finely divided ion exchange resin, and used granular anion / cation exchange. We have found that a resin mixture alone can function as a biological filter, but the most effective filter is to mix and homogenize ion-exchange resin with hydrophilic cut fibers that are compatible with water, such as rayon and polyester fiber. It was found that what was done was excellent.
[0012]
In the filtration layer A, the purification action of water by detoxifying fish droppings and residual food by biological filtration is central, and in the filtration layer B, in addition to these similar functions, an important action as a hydration source for plants. There is.
[0013]
By dividing the filtration layer into two parts, an effect of anaerobic bacteria was observed in A, and aerobic bacteria in B, particularly bacteria (biopesticides) that promoted plant growth were also observed.
[0014]
By using an ion exchange resin in combination as a filter medium, a biofiltration effect, particularly a denitrification effect, not found in other filter media was observed.
[0015]
Since the required amount of water varies greatly depending on the type of plant, a filtration layer composed of hydrophilic fibers and a powder resin is placed at the bottom of the plant root trunk, preferably the root tip and the upper end of the filtration layer B To make contact. The aquarium water purified by being forced to flow through the filtration layer A installed in the water tank is forced to flow through the filtration layer B by the forced air flow means. It has been found that returning most of the filtered water to the aquarium and sending moist air that is separated and purified from the reflux water has an unexpected effect on plant growth.
[0016]
Examples will be described below.
[Example 1]
[0017]
FIG. 1 is a schematic view of the apparatus of the present invention.
[0018]
A columnar container (10 cmH, 15 cmD) is placed inside an acrylic resin water tank (40 cmH, 20 cmD), and an equal amount of ion exchange resin, cellulose fiber, and polyester fiber are mixed therewith. Insert layer A).
[0019]
A flower pot is placed using the container inside the water tank as a support, and a similar fiber adsorbent (filtration layer B) mainly composed of an ion exchange resin is installed at the bottom of the flower pot.
[0020]
By passing a transparent pipe vertically between the bottom of the flower pot and the container installed in the center of the aquarium, and inserting air from the bottom of the pipe, the aquarium water flows through the filtration layer A due to the air lift phenomenon, Let it flow through the filtration layer B at the bottom of the flower pot. By forcing air through the aquarium water, the heat of the aquarium water is prevented, and by sending air, the temperature rise around the plant is prevented, and the surrounding environment suitable for plant growth (temperature, humidity, oxygen supplementation) Bring.
[0021]
Even if the water level drops by making a small hole in the middle of the pipe connecting the filtration layers A and B, or by connecting pipes with different diameters and adding a circulation path for aquarium water, Water circulation is ensured, and moist air is sent to the filtration layer B.
[0022]
It has been found that the filtration layer B contains hydrophilic cellulose fibers and ensures sufficient moisture in combination with the hydrophilicity of the ion exchange resin.
[0023]
It has been found that such a device not only prevents the deterioration of water quality even when the water level of the aquarium drops, but is not inferior to the growth of plants.
[0024]
5 goldfish and 1 pleco in the aquarium, 1 folded crane orchid planted in the flower pot, placed in a place exposed to sunlight for several hours through the window, and 6 months have passed. It is possible to enjoy the world of aquarium and horticulture at the same time simply by supplementing the water.
[0025]
When only herbivorous plecos are bred, if the algae survive, they can be bred without any feed, and the soil used for the flower pots has a sufficient filtration layer of ion-exchange resin fibers at the bottom. Then, it turned out that there is no problem even if the upper part is red crust, Kanuma soil, moss, and normal mulch.
[0026]
It has also been found that sending air to the root of the plant simultaneously with hydration has a positive effect on plant growth.
[0027]
By raising the temperature of the aquarium water to 25 ° C., it is natural that the breeding of tropical fish such as Goodbye has become possible. It was found that the same effect was obtained for the growth of tropical plants [ferns and sympidium] that prefer high temperature and high humidity.
[0028]
[Example 2]
[0029]
(1) A mixture of cellulose fiber and polyester fiber as follows: (2) granular activated carbon (3) granular ion exchange resin (4) powder ion exchange resin, cellulose fiber (rayon) ), Each filter medium made of an equal mixture of polyester is packed separately, and drainage containing activated sludge from a food factory is passed through each column to form a biofilm on the filter medium.
[0030]
40 p. Of ammonium nitrate. p. An aqueous solution containing m is prepared, and 20 liters of the aqueous solution is circulated through each column at a flow rate of 500 ml / h at room temperature.
[0031]
As a result, after 5 days, the nitrogen content decreased to zero only when the filter medium containing the ion exchange resin, particularly the filter medium mainly composed of powder ion exchange resin (4) was used.
[0032]
In (1), which is well known as biological activated carbon, nitrate nitrogen hardly decreased even after one week.
[0033]
As for ammonia nitrogen, it became almost zero in any case after one week, but for this, the filter medium mainly composed of powder ion exchange resin in (4) was followed by (3) granular ion exchange resin, 2) The nitrogen content decreased in the order of activated carbon and (1) a mixture of rayon and polyester.
[0034]
Regarding the generation of nitrous acid as well, only when a filter medium mainly composed of ion exchange resin (4) powder ion exchange resin is used, 5 p. p. m, but in the case of other filter media, 10 p. p. m.
[0035]
This is important for the growth of plants, and it seems that the presence of ion exchange resin is based on the fact that the action of denitrifying bacteria is activated by some action, but it is difficult to elucidate at present.
[0036]
[Effect of the invention] The world of aquarium and horticulture is enriched, and it brings moisture and healing to life. Provide a simple planter that facilitates complicated water supply work and water management, and makes it possible to grow plants easily even for the elderly and the physically handicapped.
