Description

A buoyancy structure thing to be made a plastic pipe for used a hydropornic agriculture, and that used the quality of water purification method}

The present invention is applied to hydroponic agriculture that can purify the quality of rivers or lakes by removing organic substances and nutrients in polluted water by using the nutrient intake of plants, the degradability of microorganisms and the food chain of aquatic ecosystems. The present invention relates to a plastic pipe floating structure used and a water purification method using the same, in particular, a rectangular floating frame is made of plastic pipes, a square bottom frame is suspended at the bottom of the floating frame, and the media in contact with the bottom frame are horizontally installed. It provides a habitat for micro-animals and cultivates underwater plants and aquatic plants, land plants, crops, etc. in the water space between the float and the lower frame to remove pollutants from the water.

In the case of lakes, the limiting factor of eutrophication is generally phosphorus. Natural phosphorus is derived from apatite minerals, which are calcium salts, and is included in human and livestock manure, fertilizers, washing materials, and wastewater.

Phosphorus is a conservative substance. Phosphorus introduced into the water system changes in form and distribution, but does not decrease naturally.

Phosphorus introduced into the water system exists as soluble inorganic phosphate or organic phosphorus. Algae or aquatic plants, which are phytoplankton in the water, assimilate them to synthesize nucleic acids and convert them into biological phosphorus.

Phosphorus absorbed by living organisms settles on the floor as the organism dies, and insoluble phosphorus decomposes in anaerobic state and elutes into soluble phosphorus.

Eutrophication is related to the circulation of phosphorus, and in order to prevent eutrophication, first, it is necessary to block phosphorus inflow from the basin and secondly to remove phosphorus in the body of water.

In order to reduce the inflow of phosphorus into the lake, it is necessary to use unmanned detergents and to prevent fertilizer abuse, and to manage high-level treatment and non-point pollution sources in various sewage and wastewater treatment facilities.

However, these methods require a lot of effort and cost, and in the case of domestic efforts, they do not have a clear effect.

On the other hand, the method of directly removing phosphorus from water bodies includes dredging of sediment, intake of nutrients by plants, and removal of final predators by feeding chain.

Sediment dredging method of lake bottom is expensive and water pollution is caused by resuspension of sediment during dredging work, and dredging effect is temporary problem, and method by plant and food chain is still being studied. So far no big effect.

Aquatic plants are classified according to their life types, such as reeds, buds, and edible plants, dried plants such as dried and water lilies, by-products such as water hyacinth and frog rice, and submerged plants such as Nazamak and black horses.

The aquatic plant that is currently considered to have the greatest effect on water purification is water hyacinth. The characteristics of the water purification method using this plant are as follows.

Water hyacinth is a perennial aquatic plant originating from tropical wetlands in South America. It is abundant according to the flow of water by the aeration system in the stem and can always grow and grow in a new water system. It grows and multiplies at an ideal rate to show the highest productivity in the plant kingdom and removes large amounts of nitrogen and phosphorus.

According to the "Purification Treatment by Plants of Contaminated Stream Inlet in Lakes" (1997.12), studied by the National Institute of Environmental Research, the aquatic plant's phosphorus removal capacity is higher in the order of water hyacinths> parsley, irises and babies. The ratio of cultivation area needed to achieve efficiency is water hyacinth 1, buttercup 3.3, kochangpo 4.3, and babies 7.8, which demonstrates that water hyacinth has very high phosphorus removal ability.

However, current water purification using water hyacinth, despite the merits of water hyacinth, cultivation of water hyacinth directly in the lake flows in a floating state, while floating on the screw of the ship or drifted during flooding, but it is cultivated by installing fences. Lack of maintenance, difficult to maintain, difficult to harvest due to sedimentary decay after killing, and re-elution of nutritional substances have many problems, such as the field application is not well.

As part of efforts to remove phosphorus directly from water bodies, the method of plant cultivation using Budo is disclosed in Korean Patent Publication No. 2000-8705, "Artificial Buoys for Water Purification of Freshwater Lakes". On the upper part of the floating body, a mat filled with natural fiber yarn on a net made of vegetable natural fiber is placed on the surface by filling a pot with soil and planting water purification plants on the mat. Because it is weak and easy to break and decay due to the natural fiber material, the endurance is short. Second, the default value of the natural material is decay, so it becomes a source of water pollution. Third, it is difficult to make the scale large and the buoyancy is small so that plants cannot be planted. Fourth, the ability to remove phosphorus is small, and fourth, complex facilities make production work difficult and economical. Cracking plants, such as the quality and the effect of removing a large water hyacinth was a problem that should not grow.

In addition, the Environmental Management Corporation is currently constructing a stainless steel frame at Paldang Dam, tying a styrofoam container at the bottom of the frame, laying a net of waste fishing nets on the frame, and placing a pot with water purification plants on top of the frame. A rope-shaped buiding media is installed on the rope-shaped contact media.

However, the above-mentioned buoy has a problem that the frame is made of stainless material, which costs a lot of materials, is difficult to manufacture and install, takes a lot of styrofoam buoyancy materials, and is damaged because the buoyant materials are exposed to the outside, so the safety is short and the service life is short.

In addition, since the installation amount of the rope-type media is low, the purification efficiency is low, and the rope-type media is far from the water surface and the plant roots, so it is difficult to create a high ecological space with high productivity. Difficult to apply, difficult to move and maintenance of the media and at the same time there was a problem that the cultivation of ancillary plants, such as water hyacinth with a great effect of removing nutrients.

The present invention for solving the above problems, the frame of the budodo as a plastic material is light and durable to install a high utilization and economical floating structure, the complex and various forms of space by adjoining the plant root network and the media layer As it is formed, it provides optimal growth space for aquatic micro-animals, and creates an ecological space with a high amount of water to enhance the water purification efficiency, and to be installed in a deep or low depth, and at the same time, the media is installed near the water surface. Therefore, the purpose of the microorganism is to make the use of water oxygen large and easy to maintain.

In order to achieve the above object, the present invention forms a rectangular upper frame with a plurality of plastic tube containing the styrofoam inside, and install a scaffold at a predetermined interval on the upper portion of the upper frame, the outer portion of the upper frame An upper frame formed by connecting the fence rod to the upper frame with a fence rod connecting rod at a predetermined distance from the circumference; A fence net installed downwardly over the fence of the upper frame; In the lower part of the upper frame, the lower frame formed by connecting the rope laying hole, the styrofoam bundle connecting hole and the bolted hole plate in a rectangle is fixed to the lower frame connecting rod on the two side bands fixed to the upper frame. A lower frame formed by weaving a rope contact media in a lattice shape with a rope laying hole of a lower frame; a predetermined hole is formed at predetermined intervals on the upper surface so as to be planted and float on the inner surface of the upper frame A styrofoam plate secured by a rope to a styrofoam bundle connecting hole of the lower frame; The object is achieved by forming a fence wall by connecting a rope with holes drilled up and down on the side of the lower frame connecting rod connecting the lower frame.

A styrofoam plate 23 which is connected and fixed by 22;

The side of the lower frame connecting rod 18 connecting the lower frame 17 is configured to form a fence wall by connecting the rope 25 with holes 24 drilled up and down.

The scaffold 5 is composed of a plurality of scaffolds as shown in Figure 5 and the scaffolds are fixed to the two side bands 6 in two places, and made the scaffolding legs 26 to withstand the upper load upper frame (4) It is the structure which touched the upper part.

The fence rod (7) is divided into appropriate lengths in consideration of accessibility, maintenance, etc., and watertight to receive buoyancy by covering a straight pipe (27) having a diameter smaller than the upper frame (4) on both sides with a lid (28). It is joined by a thermal fusion method.

The fence net 12 is a net in the form of a net using a fishing net or the like to block the floating of the underwater floating, large predator fish, etc. or by forming a rope-like media to hook the top of the fence rod (7) Attach one side band (8) and tie it to the ring for installation.

The upper frame (4) is integrally formed by tightly coupling the connection part to act as a floating frame to receive buoyancy in the water, and can be made by joining plastic round pipes such as PVC, PE, PP and the like by heat fusion method. High strength and durable PE pipe is most suitable.

In addition, in order to maintain buoyancy in the event of breakage of the straight pipe 2 or the curved pipe 3 of the upper frame 4, buoyant materials such as pieces of styrofoam 1 are contained in the synthetic resin mesh 29 to form the inside of the pipe (2) (3). Fill in.

The lower frame 17 is a square shape slightly smaller than the upper frame 4 and consists of a rod of corrosive steel, synthetic resin, etc., which is bolted or welded.

In addition, the ring 33 is attached to the upper portion of the one side band 34 to be fixed over the fence net (12).

Looking at the embodiment of the present invention configured as described above are as follows.

Depending on the cultivated plants, it is divided into water hyacinth cultivation and general plant cultivation. The contact media is horizontally installed, but there is a rope-type contact media 30 installation method and a plate media 31 installation method according to the media type.

The inner shape of the lower frame is different according to the installation method of the media. First, the horizontal installation method of the rope-type contact media 30 will be described. The lower frame 20 has an intermediate wall 32 in a + shape so that the frame is firm. Drill the rope laying holes 13 on the four sides of the frame 17 and the intermediate wall 32 at intervals of about 5 to 20 cm, and rotate the rope contact media 19 into the holes 13 in the horizontal and vertical directions. Lay the grid to be.

In order to prevent sagging of the media due to microbial growth, the lattice construction method is a plain weaving method that crosses the media one by one in the horizontal direction and one in the vertical direction, and then goes down one by one. Pass it through.

In order to cultivate water hyacinth with excellent ability to remove nutrients, water depth of 50 ~ 100㎝ should be secured and there should be no obstacle to water surface.

It should also not be lost during flooding and not settle down into bed after death.

Rope contact media (19) or ordinary ropes on the bottom of the lower frame (20) to cultivate water hyacinth in the open (OPEN) space between the upper frame (11) and the lower frame (20) so that these conditions are not lost or settle Install a plain weave grid mesh and the horizontal fence rope 25 is installed at a suitable interval in the connection space between the upper frame 11 and the lower frame 20.

Meanwhile, in the horizontal installation method of the plate contact media 31 shown in FIG. 4, a plurality of intermediate walls 32 are additionally formed inside the rectangular lower frame 20, and the plate media media 31 are placed thereon to be braided and wired. Secure with a back.

Hydroponic plants, ornamental plants, crops, land plants and the like can be hydroponically grown on the surface of the upper plate-shaped media (31).

In particular, the buttercups grow well at water temperatures below 15 ° C, so if the buttercups are bred from October after breeding in the summer, the phosphorus in the water can be efficiently removed.

Cultivation of these plants can float on the surface of the upper surface of the middle wall 32 inside the lower frame 17, float the styrofoam plate 23 with a plurality of formal holes 21, and set the seedling pot or directly insert the plants. Put a sponge plate with a large number of cracks in the shape of + to form a plant on the middle wall, and then plant the plants, and then use the rope 22 to attach the lower frame 17 and the middle wall 32 to prevent the Sponge Foam plate 23 or the sponge plate from flowing. Tie.

In this way, the lower frame 20 is installed with artificial media, and if a large number of media are needed according to the characteristics of the water body, the media layer can be multi-layered to install many media.

The unit frame constructed in this way makes a large group frame by combining several unit frames according to the characteristics and size of the water body to be installed.

Fig. 9 shows the cultivation of water hyacinth and water plants and the shape of each lower part as an example of a group frame combining four unit frames.

In the surface of a unit frame or a group frame, the anchoring method is connected to the upper frame by ropes and anchored to the floor or land.

This facility can be installed in public waters such as lakes or rivers, or in discharged water storage facilities, artificial non-pointed water storage facilities, ponds, etc.

In the case of rivers, there is a flow, which is advantageous for oxygen supply, and in small rivers and urban rivers, plantation water such as saruvia and mary gold can be planted to improve the landscape.

Artificial reservoirs such as effluent storage tanks of various environmental infrastructures, fertilizer runoff from high-cultivated vegetable farmland, and reservoir tanks can be used to remove nitrogen phosphorus by cultivating water hyacinths.

These small reservoirs have low flow and low float, so they only install the float body and do not install fence rods.

Low depths work directly in the water without the need for scaffolding.

However, if there are many organic matters in the storage tank without flow, the plant growth is slowed because oxygen is deficient, so it is good to install the unmanned aeration facility using the sun.

As such, this facility is a treatment facility using plants and media. In summer, pollutants are actively removed by the action of plants and aquatic ecosystems. In winter, cold plants, such as buttercups, and aquatic ecosystems continue to be removed. Proceed.

The present invention configured as described above is made of light, durable and economical plastic pipes to create a floating structure floats in the water where the algae thrive, cultivate and harvest plants, and provide a habitat for microorganisms and micro-animals such as bacteria, intake by plants, bacteria By decomposing organic matter, feeding algae on zooplankton, and food chains between micro-animals and fish, organic matter, nitrogen and phosphorus are removed from the water.

Hydroponic cultivation in rivers or lakes leads to the development of plant roots that form broad rooted nets.

The eutrophic water bodies contain algae and organic matter, phytoplankton, which adsorb to the plant's root network.

These birds and organics feed on micro-animals such as zooplankton, water fleas, hair mite larvae, fireflies larvae that live in the plant's root network. As these micro-animals grow, they create excrement and these excrements and carcasses build up between the root nets. They are broken down by small insects and bacteria and absorbed as nutrients necessary for the plant to grow the plant.

Therefore, by periodically harvesting and removing such grown plants, water and organic matter and nutrients are removed from the water bodies to achieve water purification.

In addition, micro-animals feed on small animals such as seashells, snails, dragonfly larvae, and shrimps. Food chains occur and larvae, such as dragonflies, fly to adulthood and leave water bodies.

This action removes contaminants from the waterbody and contributes to the prevention of eutrophication.

In the present invention, the contaminants in the water can be removed by plant cultivation and harvesting by the above-described method and the food chain of the ecosystem formed on the plant root network, and further, artificial media contacting the lower part of the plant root network. By installing layers, it creates a living space for microorganisms and micro-animals, so that the plant root network and artificial media layer exist within 1m of the surface of the algae where there is abundant food, and active decomposition activity in a complex space where it is easy to escape from predatory fish. And food intake and food chains will significantly increase water purification.

Dissolved organic matter in water is absorbed and decomposed by microorganisms such as bacteria, and algae and bacteria are interdependent, and algae secrete organic carbon, which is used by bacteria, and bacteria decompose organic phosphorus and used by algae.

Such bacteria play an important role in the removal of organic substances, and in the present invention, since many bacteria can inhabit the artificial media layer, the water purification ability becomes very large.

Bacteria or micro-animal habitats are made of rope-like contact media made from hydrophilic fine chemical fibers in a radial or ciliary form, or locks arranged in a plate form by crossing several strands of chemical fibers in a spring form. Use plate contact media.

These medias should be made of black or green color, have a large specific surface area, large porosity, and hydrophilicity, so that many microorganisms such as a large number of bacteria can live in a high density, and the structure is complicated and there are many large and small spaces. Plankton and smiling animals can live in and around the median layer.

This artificial contact median layer is installed adjacent to hydroponic plant roots and floated in the eutrophic waters, so zooplankton, which contributes to water purification, is abundant because it is rich in prey algae, and it feeds zooplankton. Since Loha is inhabited by many kinds of micro-animals and fish, this space grows, breeds, degenerates, rests and feeds actively, making it an ecological space with a large amount of presence.

According to the present invention, first, the frame is made of plastic, which is light and durable, so that it is possible to install a highly available and economical floating structure, and second, it is easy to cultivate hydroponic plants and harvest crops. In addition, complex and diverse spaces are formed by the adjacent installation of the plant root network and the median layer to provide optimal growth space for aquatic micro-animals and to create an ecological space with a high amount of water, thereby enhancing water purification efficiency. Fifth, it can be installed anywhere deep or low depth. Fifth, the media can be installed near the water surface, so that the use of microorganisms' water oxygen is large and easy to maintain. It is possible to grow buttercups in winter, as well as to spawn fish. , Seventh, in the light shielding effect sikimyeo prevent the photosynthesis of algae is one so that the effect of providing shade to the fish.
