Description

Pollutant treatment system for river water and early rainwater using ecological ponds

The present invention relates to a system for treating pollutants in river water and early rainwater using an ecological pond, and more particularly, to a space into which a non-point source such as polluted river water or early rainwater, such as a river basin, can be introduced. After installing artificial ponds and inflowing the initial rainwater or nonpoint pollution initial rainwater contaminated with artificial ponds, if the riverwater or nonpoint pollution initial rainwater filled with artificial ponds is filled, stop the inflow of contaminated riverwater or initial rainwater pollution, During the suspension period, the organic matter in the artificial pond is attached to the vegetation and soil layers, so that the organic matter is decomposed by the soil microorganisms and the chromaticity can be reduced, so that the polluted river water or the non-point pollution initial rainwater can be purified. It relates to a pollutant treatment system of rainwater.

In general, one of the objectives of implementing a total pollutant system is to recover the water quality of the stream, that is, reduce the BOD of the stream. Methods for this purpose include treatment of point sources, treatment of nonpoint sources, direct treatment of river water, etc. In particular, the present invention to recover the water quality of the river water by directly purifying contaminated river water, or legally treated and discharged It is to further reduce the pollution load flowing into the river by further treating the residual organic matter in the waste water discharged.

On the other hand, in the treatment of pollutant sources, the discharge of industrial wastewater or sewage is strictly regulated as it causes environmental pollution. Therefore, the wastewater purification treatment facility is installed to purify and discharge to the stream. It is against the law. Therefore, the existing methods of purifying sewage and wastewater to meet the discharge allowance are known to be purified by the sedimentation method and the oxygen supply method by the aeration system. In addition, depending on the quality of the waste water, the purification method using chemical products is mainly utilized.

However, since the existing wastewater purification treatment method is artificial and chemical treatment method, it requires a lot of effort to purify it, and the purification facility also needs to be extensive, and it must be managed by professional personnel. There is a problem that a lot of expenses are spent on the purification process, and in particular, the existing wastewater purification treatment facilities are usually cleaned inside the plant where no one can enter, so it is difficult to supervise the wastewater. Since it is practically difficult to discharge into river water, there has been a limit in maintaining clean river water.

Meanwhile, Korean Laid-Open Patent Publication No. 2000-72363 discloses a stormwater silt 21 in which an inflow pipe sluice 23 connected to a flow distribution tank inlet pipe 22 at a predetermined position of the water channel 11 is formed at a predetermined position on one side wall. and; A flow distribution tank 24 through which wastewater flows along the flow distribution tank inlet pipe in the rainwater chamber 21; A sedimentation basin manhole (25) connected to the settling basin pipe (26) from the flow rate distribution tank (24); The purified water flowing into the sedimentation basin manhole 25 is discharged to the water channel 11 by using the submersible pump 47, while the water that is pumped up by the submersible pump 47 discharges the unpurified water. Take the water pipe (48) back to the flow distribution tank (24) and then the wetland inflow pipe (27) is introduced into the wetland inlet pipe manhole 28 separately installed on both sides and the water introduced is the wetland inflow pipe ( Wetland areas (41a) (41b) (41c) divided into angular sectors flowing through the stream (27); Mosquitoes such as mosquitoes can be generated in the wetland at a predetermined position in the wetland area, so that the moth larvae eat a loach, a frog, etc., which can be installed; A machine room (44) installed at an outer region of the wetland region and having a blower (44a) installed therein to blow air into the air discharge pipe (44b) piped at predetermined intervals into the lower filter layer of the wetland region; The wetland areas (41a) (41b) (41c) as a natural purification promoting device using artificial wetlands formed by planting aquatic plants in the filter layer 42 formed by filling large gravel, small gravel, royal sand, sand. Form a wetland filter layer and settled area, supply air to the wetland filter layer, fill sand, gravel, etc., and then introduce wastewater into the wetland filter layer to create artificial wetlands, grow and harvest aquatic plants in artificial wetlands, After purging nutrients, the wastewater is filtered while passing through the filter layer, decomposed by microorganisms and introduced into the sedimentation basin. Known.

In addition, the Utility Model No. 220403 is an advanced treatment device for treating living sewage containing eutrophic substances such as nitrogen and phosphorus with microorganisms and wetland plants, and the sewage discharged from the septic tank 1 is applied to the trench 3 by a predetermined amount. Flow control tank (2) for adjusting the flow rate to be supplied, trench (3) for decomposing odorous substances by anaerobic microorganisms under anaerobic conditions, filter tank (4) for decomposing organic matter by aerobic microorganisms inhabiting crushed stone (19), filter tank (4) flow control tank for the wetland (5) for absorbing and removing the undecomposed organic matter in the buttercup (18), the pond (6) for storing the treated water discharged from the wetland (5), the treated water in the pond (6) The sewage treatment apparatus using the conveyance wet method which consists of the 1st conveyance pipe 8 which conveys by (2), the 2nd conveyance pipe 10 which conveys the sediment of the pond 6 to the septic tank 1, etc. is known. .

However, all of these methods have to use complex mechanical devices as wastewater treatment facilities, and because they focus on functions, overlooking the efficiency of space, it is difficult to consider ecological features and there are landscape problems. Not only was there a problem that it was unsuitable to be treated and actually impossible to implement, and it was impossible to reduce residual organic matter and color in contaminated river water.

In addition, the existing systems using wetlands form a simple system that arranges cells in which vegetation is densely arranged in parallel or in series, or forms a system by properly mixing and arranging wetlands with ponds and vegetation. Existing systems have been designed and constructed with a focus on water treatment, neglecting the provision of habitats for wildlife, environmental education, and landscape.

In another aspect, it is urgent to purify non-point sources that cause contaminated river water. Non-point sources are cities, roads, farmland, mountains, construction sites, etc. Refers to the source of discharge. (Article 2 No. 2 of the Act on the Conservation of Water Quality and Aquatic Ecosystems)

Point pollutants are easy to collect due to the clear outflow path of pollutants, and can be predicted annually due to the relatively small seasonal influences, so that treatment facilities such as conduits and treatment plants (eg, water quality and water ecosystem conservation) By law, it is easy to design and maintain / manage wastewater discharge facilities of factories and workplaces, whereas nonpoint source sources are difficult to collect due to the inflow and discharge paths of pollutants, which are difficult to collect and It is difficult to design and maintain the treatment facility because it depends heavily on weather conditions such as precipitation.

In other words, point sources and nonpoint sources are relative concepts. For example, factories that discharge plant wastewater that are collected through conduits and treated through water pollution prevention facilities are point sources, while they do not undergo other treatment. Factory sites, such as yards that discharge incoming rainfall runoff, are nonpoint source.

These non-point pollutions include fertilizers and pesticides that are not absorbed by the crops and remain in agricultural land, manure that is grazed in grasslands, untreated livestock waste discharged from livestock farms, air pollutants mixed with rainwater, sediments on road surfaces, and consolidation sewerage. There is a mixed water of sewage / sewage and rainwater flowing into the river in excess of the design amount during rainfall, and the types of major pollutants of the nonpoint source are as follows.

(1) Sediment

 In soils, nutrients, metals, hydrocarbons, and other contaminants are adsorbed and move together, and they make up a large portion of rainfall runoff, causing a fatal effect on aquatic organisms' photosynthesis, respiration, growth, and reproduction.

(2) Nutrients

 Nutrients such as nitrogen and phosphorus are used as fertilizers, which are often leaked by rainwater to promote algae growth, worsening the quality of rivers and lakes, and flowing out of lawns, farmland, urban roads and sewers in houses and golf courses. Inflow.

(3) Bacteria & Viruses

 It is frequently detected in animal wastes and overflows from sewers. In the United States, high concentrations of bacteria and viruses in rainfall runoff have caused streams and lakes to be contaminated, leading to closure.

(4) Oil & Grease

 Oil and grease can be fatal to aquatic life, even in small amounts. Pollution occurs during accidents such as leaks, vehicle overturns, vehicle cleaning, and dumping of waste.

(5) Metals

 Heavy metals such as lead, zinc, cadmium, copper, and nickel are commonly detected in rainfall runoff in urban areas, and more than 50% of the total amount of metals flowing into rivers is discharged through soil, which is fatal to aquatic ecosystems. Special care is required because bioaccumulation takes place and there is a possibility of drinking water contamination.

(6) Organics

 It flows from a wide range of places such as fields, rice fields, forests, and residential areas. Especially in confluence, organic materials contained in sewage and sewage, which flow through sewage pipes at low flow rates, are deposited at the bottom of the pipes, and are discharged at the time of rainfall. In industrial areas, artificial organic compounds such as adhesives, cleaning agents, and solvents are widely used, resulting in improper storage and disposal.

(7) Pesticides

 Insecticides such as herbicides, pesticides and antifungal agents can accumulate in aquatic organisms such as plankton, causing bioconcentration through the food web, which can be fatal to fish and algae.

(8) Gross Pollutants

 Garbage, residues and suspended solids generated at construction sites and workplaces may contain heavy metals, pesticides, bacteria, etc. It is a carrier for transport and reduces dissolved oxygen, which can cause fish deaths.

In this way, non-point sources are pollutants such as suspended soils such as earth and sand, nutrients such as nitrogen and phosphorus, and high concentrations of heavy metals that are difficult to collect and treat due to rainfall. Therefore, aquatic ecosystems are disturbed due to mass deaths of fish or destruction of benthic habitats. Also, the increase of impermeable layers due to land development increases the amount of rainwater that is not absorbed into the soil during rainfall or discharged to rivers. Increased risks and reduced groundwater replenishment can also be a factor in the stream's dryness.

Conventional techniques for treating such nonpoint sources include natural facilities such as reservoirs, artificial wetlands, infiltration facilities, vegetation-type facilities, filtration-type facilities, vortex-type facilities, and screen-type facilities.

In the case of storage tanks, heavy rains in summer require large-scale land or equipment, and if untreated water is kept, pests such as flies and mosquitoes are generated, which causes hygiene problems.

Infiltration type causes soil clogging due to inflow of soil or floating material during construction, and vegetation type requires more than a certain amount of land and conditions for maintaining vegetation, but it is difficult in case of having four seasons like Korea. There is this.

The device-type facility has been designed and constructed with a focus on water treatment, which has neglected the provision of habitats for wild animals and plants, environmental education, and landscape aspects.

Recently, since sewage pipes are classified pipes, treatment for non-point pollutants spilled in rainwater is required, and various technologies have been developed for methods and devices for removing non-point pollutants generated during development and rainwater.

In Korean Utility Model Registration No. 426715, the initial excellent effluent from which the contaminant is filtered by the filtration net in the sedimentation tank, which is a hollow tank, flows into the storage tank to deposit various sludges contained in the initial excellent effluent while storing the initial excellent effluent. Is a hollow transparent box-shaped hollow carrier, and a purifier including a carrier box having one or more pipe fittings at a lower surface thereof is installed at a lower position than the settling tank, and is connected in communication with the top of the storage tank of the settling tank. There is known a non-point source initial excellent outflow water purification treatment system for purifying the initial runoff water precipitated in the inside of the carrier to purify the outflow of the initial excellent water by the nonpoint source.

In addition, Korean Patent No. 883436 purifies non-point pollutants such as rock, gravel and suspended solids generated from nonpoint pollutants as well as organic substances, nitrogen and phosphorus and sends them to the river to prevent water pollution caused by nonpoint pollutants. A non-point source treatment apparatus capable of reducing the load of organic substances flowing into a water purification plant through a sedimentation unit for separating foreign matters from inflow rainwater by a difference in specific gravity and a first biofilm for removing organic matters from rainwater flowing out from the sedimentation unit. A non-point source treatment apparatus using a biofilm comprising a treatment portion and a second biofilm treatment portion for removing nitrogen and phosphorus in rainwater flowing out of the first biofilm treatment portion has been developed.

In addition, the Korean Patent No. 912458 has a first sedimentation tank 110 to guide the flow of rainwater U-shaped and outflow; The first filter member is installed in accordance with the flow hole of the upper side wall from which the rainwater flows from the outside of the first sedimentation tank 110 to the first sedimentation tank 110, and adsorbs and filters the oil component contained in the rainwater. 120; Dig a small amount of accommodating space under the area where the effluent water treatment system is to be formed, and crush the ground to form rubble, and form the bottom and sidewall of the accommodating space with a porous thickness of a predetermined thickness by a porous material. A second settling tank 130 formed with a filtration member 105 in a padded state to settle the sludge, inducing a flow of rainwater into a U-shape; The second filter member 140 is installed in accordance with the water flow hole of the upper side wall from which the rainwater flows from the first sedimentation tank 110 to the second sedimentation tank 130, and adsorbs and filters the oil component contained in the rainwater. )Wow; It is formed in a state of blocking a vertically to a predetermined depth to cross the center to guide the rain flow downward to the U-shaped, covering so as to cover the upper portion of the first settled tank 110 and the second settled tank 130, respectively. A cover 150; Relatively lower the area under which the rainwater flows from the second settling tank to form the effluent treatment system and then dig the foundation gently with a natural vegetation reservoir structure, and then plant the upper part of the chopped foundation. B. Planting the vegetation on the filtration member in a state in which the filtration member 105 'including the plant seed layer of the root is padded, thereby storing the rainwater from the second sedimentation tank 130 and purifying ecologically while flowing to the reservoir. Non-point source effluent purification systems are known that comprise an ecological purification tank.

In addition, various techniques are known, such as the initial excellent purification treatment apparatus of Korean Patent No. 0779513 and the non-point contaminant purification apparatus of the initial effluent of No. 561092, but most of them are limited to physical treatment methods such as sedimentation and filtration.

Hereinafter, with reference to Figures 1 to 5 will be described in detail the contaminant treatment system of river water and the initial excellent water using the ecological pond of the present invention.

Ecological pond of the present invention is an artificial pond 101 designed in a variety of shapes (symbol mark, character, logo, etc.) in the space into which contaminated river water or non-point pollution initial rainwater can be introduced, and the lattice tunnel on the bottom of the artificial pond Natural filtration runway 102 formed in the shape, the filter soil layer 103 is filled with Masato and volcanic stone on the top of the natural filtration runway and the microbial decomposition occurs, and the planting portion 104 planted aquatic plants in the filter soil layer And a sump 105 which is in communication with the natural filtration outflow path to collect purified effluent water.

The various shapes of the artificial pond design as shown in Figures 4 to 5, the biggest feature of the present invention is to use a symbol mark, a character or a logo used in each municipality. Daejeon, Figure 5 is a symbol mark of Hadong-gun)

Referring to Figures 1 to 3, when explaining the process of purification of the contaminated river water or non-point pollution initial rainwater of the ecological pond, the initial flow of river water or non-point pollution contaminated by the inlet pipe and fountain flows into the artificial pond 101 When the water level becomes high, the inflow of contaminated river water or non-point pollution initial rainwater is stopped, and the contaminated river water or non-point pollution initial rainwater is filter soil layer consisting of masato and volcanic stone layers and microorganisms for a predetermined time in the artificial pond. Natural filtration adsorption by) and decomposition and purification by microorganisms are performed simultaneously.

As the natural filtration adsorption and the decomposition and purification by microorganisms are progressed, the natural effluent is collected into the sump 105 through the natural filtration outlet 102, and the organic matter adsorbed by the filter soil layer 103 is While it is decomposed by microorganisms in the filter soil layer.

The artificial pond 101 is formed in the open air, and is exposed to the outside in an open state to facilitate spontaneous and environmental supervision, and the size of the artificial pond 101 in consideration of pollution degree of river water, etc. The filtered and purified river water or initial rainwater which has been set and passed through the artificial pond 101 is discharged back to the river via the reservoir 105.

The catchment 105 is a place where the purified river water or the initial rainwater is collected and installed at a lower position than the natural filtration outlet 102 of the ecological pond. Through the natural flow through, and when the water level of the reservoir 105 reaches a predetermined level or more is designed to be discharged through the overflow pipe (not shown).

The bottom of the artificial pond 101 is filled with a filter soil layer 103, the filter soil layer 103 is composed of a mixture of Masato and volcanic stone.

Masato is a soil produced by the weathering of granite. It is called “masato,” which is widely used in field crops, landscaping plants, wildflowers, bonsai, and flower pots because of its excellent drainage and breathability. Masato used in white horses.

White horse sand is a soil similar to stone powder that contains little clay. It has excellent drainage, high oxygen content in soil, and is used by mixing masato and leaflets in 7-3. It is used for transplanting pine tree, gardening plant, camphor ginseng, and seeding of ginseng because it is easy to form roots. It is especially used for school grounds, courtyards, tennis courts, etc. because it has excellent drainage and softness.

Volcanic stone is a kind of volcanic ash that is caused by the burning of clay by high temperature volcanic heat and can be found in the terrain formed by volcano. In Korea, it is easily found on Jeju Island, a volcanic island.

Volcanic rocks generate anions at room temperature and are known as ideal natural materials that emit more than 92% of infrared rays at room temperature (below 40 ℃). Volcanic stone is porous, and has excellent water absorption and breathability than other rocks. The volcanic stone has a fire resistance of 1120 ° C to 1210 ° C, an absorption rate of 17.7% to 32.5%, and a wear rate of 47.25% to 67.22%. The fire resistance, absorption rate and wear rate of volcanic stone are higher than that of ordinary gravel or sand.

Volcanic stones consist mainly of silicon oxide, aluminum oxide, and iron oxide, and include titanium dioxide which is absent in ocher, jade, elvan, germanium, and the like. Titanium dioxide is present in the volcanic stone 3 to 7%, and performs a photocatalytic reaction, the active oxygen is produced by the photocatalytic reaction of titanium dioxide, the active oxygen oxidizes air pollutants, water pollutants, and odorous substances, etc. Disassemble. According to the photocatalytic action of titanium dioxide, volcanic stone has semipermanent functions such as antibacterial, sterilization, deodorization and organic decomposition.

In addition, the volcanic stone absorbs moisture when the humidity is high, and it discharges moisture when the humidity is low, so that the natural humidity can be controlled without an artificial device.When the volcanic stone is put into the aquarium, moss does not occur in the aquarium, and The wound healing ability is also improved, and when put in the pots of plants, they survive longer than the normal plant survival time, and when the volcanic stone is put in the refrigerator, there is a deodorizing function in which the odor of the refrigerator is removed.

The mixture of Masato and volcanic stone in the filter soil layer of the artificial trench is used to filter and purify the river water. The particle size of Masato and volcanic stone is less than 2mm, and the volume ratio of Masato and volcanic stone is Masato 50 ~ 70%, volcanic stone 30 Use at 50%.

As described above, the particle size of Masato and volcanic stone is 2 mm or less, and the mixed volume ratio of Masato and volcanic stone is 50% to 70% for Masato and 30% to 50% for volcanic stones to improve the filtration efficiency of river water, drainage time, and purification efficiency by microorganisms. This is because it can maintain the most appropriate.

In addition, the depth of the ecological pond and the depth of the filter soil layer is characterized in that each formed to a depth of 0.5 ~ 1.0m, the depth of the flow time of river water, the ecological characteristics of the vegetation, the depth of the filter soil layer, decomposition of microorganisms Determining the speed and the structure and shape of the artificial pond, the most preferable depth was 0.5 ~ 1.0m. The depth of the filter soil layer was high in the winter when the depth of the filter soil layer was shallow. It is preferable to maintain the depth of the filter soil layer to 0.5 ~ 1.0m for the purification process.

In addition, the filter soil layer comprises a planting portion 104 is aquatic plants are planted, the river water or the initial excellent water flowing through the artificial pond is not only filtered naturally flowing by the filter soil layer, the viability of the planting portion Strong plants and plants (e.g., buttercups, moon roots, reeds, ropes, babies) are planted and grow in accordance with sunlight and ecosystem principles, thereby maintaining the cleansing power of the filter soil layer. In particular, plants or plants filter It is known that aerobic microorganisms are generated by the ecosystem principle when the root layer 103 is rooted, and the purifying power can be maintained as the microorganisms continue to generate and grow by this principle.

In addition, the filter soil layer 103 is a natural oxygen supply during the passage of the river water or the initial excellent water between the constituent particles, which causes the active decomposition of microorganisms, which is exposed to the atmosphere of the artificial pond 101 It is possible because the ventilation of the inside of the filter soil layer is made, and since the artificial pond is formed in various sizes, sufficient oxygen can be dissolved during the retention of river water or initial rainwater.

In addition, the natural filtration outflow path space formed in the lattice tunnel type can be further decomposed organic matter contained in the river water or the initial excellent natural filtration in the filter soil layer by installing a microorganism media that can be attached microorganism well.

On the other hand, during the purification process of the ecological pond by the inflow pipe and the fountain 100, the river water or the initial rainwater flows into the artificial pond 101 and stops the inflow of the river water or the initial rainwater during the stopping period, the river water during the suspension period Alternatively, if the initial excellent water stays in the artificial pond, the natural filtration adsorption and purification by the microorganism by the filter soil layer 103 composed of Masato and volcanic stone layers and microorganisms are simultaneously performed. The filtered effluent is collected to the reservoir 105 through the natural filtration runway 102, and the organic matter filtered by the filter soil layer 103 is decomposed and purified by the microorganisms of the filter soil layer for a certain period of time, and then again into the river water or the initial stage. It is the biggest feature of the present invention to repeat the inflow, suspension, inflow cycles that introduces rainwater, Group can be controlled according to the processing capacity of an artificial pond, river water or contamination, microbial degradation rate of the initial solid.

As another embodiment of the present invention, the ecological pond is installed in two or more multiple, it characterized in that the inlet, stop, inlet cycles alternately. In other words, when two artificial ponds are inflow periods, one artificial pond is a period of inflow of water, and another artificial pond is a suspension period (filtration and microbial decomposition period). This is an advantage of not only efficiently using the surrounding space, but also increasing the processing capacity of the ecological pond. In addition to the case of two artificial ponds, three or four multiple artificial ponds may be installed depending on the surrounding space. It may be.

In addition, as shown in FIG. 1, when seven or more ecological ponds are installed in multiples, a unique sound informing the inflow of one artificial pond during the inflow period of river water (eg, island, ree, wave, The sound effect may be generated by generating any one of sol, la, poetry, etc., and visual effects by allowing river water or initial rainwater to flow through inflow pipes and fountains so that river water or initial rainwater can flow into the ecological pond. It may also indicate.
