Description

{FLOATING AND SUBMERGING TYPED ARTIFICIAL WETLAND}

The present invention relates to a floating water immersion type multifunctional artificial wetland, and more particularly, to a floating water immersion type multifunctional artificial wetland having a built-in wet type water-repellent type water-repellent structure.

It is applied to the water treatment of rivers, village sewage, nonpoint pollution sources, reservoir influent. Ecological water treatment technology using artificial wetland is a natural friendly method, and there is no secondary pollution, there is no power consumption due to chemical and mechanical devices, maintenance cost is cheap, and advantage of using treatment facility as ecology learning field It is a technology that is getting popular recently.

However, current technology imitates natural wetland as it is, and it takes a long time to remove pollutants from the water. In addition, there is a problem that a lot of land required according to the composition of the wetland is needed. Most of the rivers and lakes are privately owned except floodplain, so it is very difficult to secure the site to be constructed.

In the case of conventional wetlands, both drought and flood problems arise. In floods, flooded water is flooded, causing problems such as scouring, deposition, erosion, and overcoating. In the event of a drought, the water level of the wetland is lowered, The function will be lost.

In addition, the conventional artificial wetlands have not been effective due to lack of ability to cope with water quality change. That is, it is difficult to adjust the water level arbitrarily, and the fluctuation of the residence time becomes severe, so that the treatment efficiency is not stable.

In addition, there is a case where a floating wetland is formed in the form of a boulevard on the water surface for purification of the lake. However, this is a form that only the aquatic plant habitat is formed in the open water, and the water purification effect is insufficient.

In addition, the conventional artificial wetland has a purification mechanism by a natural method comprising water flow, aquatic plants and symbiotic organisms, and the treatment efficiency is somewhat lowered. Particularly, when the inflow concentration of the inflow water is high, the corruption phenomenon occurs, problems such as bad odor and poor growth of aquatic plants are generated, and the purification function is lost.

FIG. 1 is a schematic view showing a cross-sectional structure of a flooded immersion type multifunctional artificial wetland 1 according to the present invention, and FIG. 2 is a plan view showing a planar structure of a flooded immersion type multifunctional wetland 1 .

As shown in the figure, the flooded immersion type multifunctional artificial wetland 1 according to the present invention is floated on the water surface by the float body 100, and several independent wetland reactors are manufactured for each function, Lt; / RTI > The raw water is supplied through the inflow pump 110 and is purified and discharged during the sequential movement of the plurality of independent wetland reactors through natural descent.

The float-flooded multi-functional wetland 1 according to the present invention includes a buoyant body 100 forming buoyancy, a plurality of independent wetland reactors 200, 300, 400, 500 supported by the buoyant body 100 and floated on the surface of the water, .

The wetland reactors 200, 300, 400, and 500 include a microorganism reaction tank 200 for treating raw water with water-treated microorganisms, a sedimentation-and-wetting portion 300 for purifying contaminants by physically sedimenting the raw water, A shallow wetland part 400 and a deep wetland part 500 for discharging the treated water to the outside.

The buoyant body (100) is formed to accommodate a plurality of wetland reactors (200, 300, 400, 500). As shown in FIG. 2, the buoyant body 100 is formed in the form of a rectangular frame, and a plurality of wetland reactors are disposed in a space surrounded by the buoyant body 100. At this time, the buoyant body 100, the microbial reaction tank 200, the sedimentation-and-wetting portion 300, the shallow wetting portion 400, and the deep wetting portion 500 are fixed to each other by the connecting body 600.

One end of the buoyant body 100 is provided with an inflow pump 110 for supplying raw water W1 to the microorganism reaction tank 200. The inflow pump 110 supplies the raw water W1 to the microorganism reaction tank 200 through the raw water supply pipe 111. [

In the flooded immersion type multifunctional artificial wetland 1 according to the present invention, the raw water W1 is supplied to the microbial reactor 200 through the inflow pump 110 forcibly. Therefore, the amount of the raw water W1 supplied to the microbial reactor 200 through the inflow pump 110 can be controlled to be constant.

The amount of raw water W1 supplied to the microorganism reaction tank 200 can be controlled to be constant, so that the treatment effect can be stabilized. In addition, since the residence time can be freely adjusted by adjusting the inflow amount of the inflow pump 110, there is an advantage that the inflow concentration can be flexibly coped with a long-term change in inflow concentration.

On the other hand, an air supply unit 120 is provided on the upper surface of the buoyant body 100. The air supply unit 120 is connected to the air pipe 210 and the air supply pipe 211 that supply air to the microbial reaction tank 200. The air generated from the air supply unit 120 is continuously supplied to the microbial reaction tank 200 through the air intake pipe 211 to improve the treatment efficiency of the microbial reaction tank 200 .

The buoyant body 100 also functions to support the solar power generation unit 130 in addition to forming buoyancy so that the plurality of wetland reactors 200, 300, 400, and 500 can float on the surface of the water. The photovoltaic power generation unit 130 generates power using sunlight and supplies power necessary for driving the inflow pump 110 and the air supply unit 120 described above.

The solar power generation unit 130 converts the solar energy generated by the solar power generation panel into a form that can be used in the inflow pump 110 and the air supply unit 120, A battery for storing electric energy converted by the converter, and a control unit 140 for controlling the driving of the solar power generating unit 130.

The control unit 140 supplies power to the battery according to a driving condition of the inflow pump 110 and a driving condition of the air supply unit 120, which are input by an administrator through an input unit (not shown).

The microorganism reaction tank 200 biologically treats the raw water W1 flowing through the inflow pump 110 using a water treatment microorganism. The microbial reactor 200 is implemented in a contact oxidation manner. To this end, a plurality of microorganism contact media 220 are disposed inside and an air diffuser 210 for supplying air to the inside is provided.

The microorganism reaction tank 200 processes the raw water using the adhered growth microorganisms. The microorganism reaction tank 200 is provided in the form of a water tank with an open upper part and the primary treated water W2 obtained by first treating the raw water W1 flowing through the inflow pump 110 is immersed in the submerged wet tissue 300).

The microbial contact media 220 is provided to increase the holding capacity of the adhered growth microorganisms. Since oxygen is continuously supplied from the air diffusing pipe 210, contaminants in the raw water W1 are stably removed even when the inflow concentration is high, And the deep wetland part 500 can be stably maintained.

Various known types of microbial contact media 220 can be used.

The primary treated water W2 treated first in the microorganism reaction tank 200 is discharged to the acupuncture and wetting part 300 through the primary treated water discharge pipe 230.

The acupuncture and wet tissue part 300 secondarily treats particulate pollutants of the primary treated water W2 flowing from the microbial reaction tank 200 and the biofilm which is excessively desorbed and removed.

The flooded wet paper 310 is floated on the upper part of the flood damper 300 so as to enhance sedimentation efficiency by the root a of the aquatic plant A and to prevent sedimentation by the aquatic plant A and the symbiotic microorganisms Thereby realizing a pollutant removal effect.

The sedimentation and storage section 300 is provided in the form of a water tank of 1.2 m or more in depth, and the substance to be removed is a substance such as particulate pollutants and desorption biofilm. As the aquatic plant (A) is planted in the floating wetland (310), the aggregation and sedimentation effect by the plant root (a) can be maximized and the propagation of algae can be suppressed.

Since the plant root (a) is formed long to the lower part of the water surface through the floating wet paper 310, the particle type organic matter and the colloidal material having a very low sedimentation rate as pollutants in the water flowing into the inside are collided, So that the particles are aggregated into larger particles so as to sink to the bottom.

In addition, the plant root (a) plays a role of a microorganism-contacting filter medium, and plays a role of biologically decomposing and removing contaminants in the water caused by microorganisms adhering to and growing on roots.

The acupuncture and wetting portion 300 is connected to the shallow wet portion 400 by the second water discharge pipe 320 and discharges the second treated water W3 to the shallow wet portion 400.

The shallow wetland part (400) is formed in the form of a surface flow wetland. The shallow wetland part 400 is provided with a water tank having a depth of about 0.5 m and a first vegetation base 410, 410a, 410b having a depth of about 30 to 40 cm. A first aquatic plant (B) is planted on top of the first vegetation base (410, 410a, 410b).

The secondary treatment water W3 flowing from the stomach and hydrangea 300 passes through between the first aquatic plants B and is subjected to the tertiary treatment while undergoing the processes of flocculation, adsorption, absorption, oxidation and decomposition.

The first vegetation bases 410, 410a, and 410b may be formed in various forms according to needs, such as gravel, crushed stone, sand, ceramic balls, volcanic stone, coconut fiber, cashmere, artificial fiber,

A plurality of the first vegetation bases 410, 410a, and 410b may be arranged in a line in the acupuncture and moxibustion part 300. At this time, flow control partitions 420 and 420a for flowing the flow of the secondary treatment water W3 between adjacent vegetation bases 410, 410a, and 410b in a vortex shape are provided. The flow control ribs 420 and 420a prevent the secondary treatment water W3 from drifting in the shallow wet part 400 and pass through the first vegetation bases 410, 410a and 410b in a zigzag form Thereby maximizing the residence time and improving the pollutant removal effect.

The shallow wetland part 400 discharges the third treated water W4 to the deep wetland part 500 through the third treated water discharge pipe 430. [

The deep wetland part 500 receives the tertiary treated water W4 subjected to tertiary treatment through the shallow wet part 400. The deep wetland section 500 serves as the final settling and effluent reservoir. The second wet vegetation base 510 is formed along the inner side of the water tank and the second aquatic plant C is formed in the second vegetation base 510. The second wet vegetation base 500 is provided with a water depth of about 1m / .

The tertiary treated water W4 is brought into contact with the second vegetation base 510 and the second aquatic plant C of the deep wetland part 500 and finally the foreign matter is settled and treated fourth. The quaternary treated water W5 subjected to the fourth treatment is discharged to the outside through the fourth treated water discharge pipe 520.

The raw water treatment process through the floating inundation type multifunctional artificial wetland 1 according to the present invention having such a configuration will be described with reference to FIGS. 1 and 2. FIG.

The float-immersion multifunctional artificial wetland 1 of the present invention is formed on the water surface of the lake. The float body 100 is arranged in a rectangular frame form on the surface of the lake and a plurality of independent wetland reactors 200, 300, 400, 500 are disposed in an inner space formed by the buoyant body 100.

At this time, the raw water W1 of the lake is introduced into the microbial reactor 200 through the inflow pump 110. The independent wetland reactors 200, 300, 400, and 500 include a microbial reactor 200, a sedimentation and habitat 300, a shallow wetland 400, and a deep wetland 500. The arrangement position and the arrangement size of these can be adjusted in consideration of the size of the aperture and the contamination concentration.

A plurality of wetland reactors (200, 300, 400, 500) are connected to the buoyant body (100) by a connector (600). At this time, the water tanks forming the respective wetland reactors 200, 300, 400 and 500 are manufactured in various materials and shapes such as STS, STEEL, FRP, PVC, separator, and the like depending on conditions of the target water body to be installed. .

Since the plurality of wetland reactors 200, 300, 400, and 500 are installed in a submerged state in water, a large load is not generated, so that the buoyant force is not excessively consumed and the state connected to the buoyant body 100 can be stably maintained.

The plurality of wetland reactors 200, 300, 400, and 500 may be individually separated and moved for ease of transportation, and may be freely adjusted in size and arrangement position through a parallel connection using a connection pipe (not shown) and a connector 600.

As a result, it is possible to apply a wide range of applications such as golf courses, parks, and other small appeals to agricultural reservoirs, dam reservoirs, and stagnant water areas.

However, in order to actively cope with the contamination concentration of the raw water, it is preferable that the microorganism reaction tank 200 is disposed in the initial flow path of the raw water W1.

The raw water W1 is introduced into the microbial reactor 200 by the inflow pump 110. A plurality of microbial contact media 220 are disposed in the microbial reaction tank 200 to increase the amount of water-treated microbes retained and to continuously supply oxygen by the air diffuser 210 to improve the water treatment efficiency.

The primary treated water W2 subjected to the biological treatment by the microorganism is transferred to the sedimentation and storage section 300 through the primary treated water discharge pipe 230.

The primary treated water W2 transferred to the acupuncture and wetting part 300 is brought into contact with the root a of the aquatic plant A formed in the floating wetland 310 and the particulate pollutant is secondarily treated. The secondary treated water W3 secondary treated in the acupuncture and wetting part 300 is moved to the shallow wet part 400 and flows between the plurality of first vegetation bases 410, 410a and 410b through the flow control partitions 420, And contacted with the first aquatic plant (B) and the symbiotic microorganism, and subjected to tertiary treatment.

The tertiary treated water W4 is contacted with the second aquatic plant C in the deep wetland part 500 and subjected to the fourth treatment, and then discharged to the outside through the fourth treated water discharge pipe 520.

According to the present invention having such a configuration, the inflow amount of the raw water can be controlled by the inflow pump constantly, so that the treatment effect can be stabilized. In addition, since the raw water is forcedly introduced through the inflow pump, it can be disposed in various places according to the position of the suction port as well as the contaminated lake water can be installed in the lake.

Particularly, when the treatment facility is located on the water surface and the inflow line is installed on the inflow side stream, the inflow source having a high degree of contamination can be intensively treated.

In addition, the floating flooding type multifunctional artificial wetland of the present invention floats on the water surface and maintains the water level in a certain wetland, so that flooding and drying damage of the aquatic plant are not generated. In other words, the wetland on the surface of the water can maintain a stable treatment effect in both the wet season, the flood season and the flat water season.

In addition, since the floating flooding-type multifunctional artificial wetland of the present invention is formed on the water surface of the lake, it is possible to completely solve various problems that have arisen in the past. In addition, since the inflow pump and the air supply unit, which require electricity, are produced by the solar power generation unit itself, the maintenance cost is not generated and the underwater cable construction for power supply is not required. Can also be free.

In addition, the artificial wetland of the present invention includes a microbial reaction tank in the inflow path of raw water, and treats raw water by a biological water treatment method. Therefore, even if the inflow concentration is high, contaminants are removed through the biological treatment, so that the settling wetland portion, the shallow wetland portion and the deep wetland portion at the downstream end can treat the treated water stably.

The embodiments of the floating flooding type multifunctional artificial wetland of the present invention described above are merely illustrative and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. .
