Description

Quality of water specie system of the lake}

The present invention relates to a lake water purification system for improving the water quality of contaminated rivers and lakes, and more specifically, to form a small stream having an aeration tank, a sedimentation tank and a filtration tank at the edge of the lake to continuously circulate the water of the lake. The present invention relates to a lake water purification system capable of improving the water quality at a low cost while allowing the lake to have a natural form of self-cleaning ability.

Water quality improvement in the lake is also important to improve the water quality in the lake through the removal of contaminated sedimentary layers and to reduce the pollutant load of the streams flowing into the lake.Many water purification devices and purification methods have been developed to reduce the upstream pollutant load. It has been verified to be functional, and various types of catalytic oxidation processes have been applied in the field, and many media have been developed to improve the efficiency of contact media, and in recent years, many artificial alternative media have been developed. In addition to the removal of organic pollutants, high-efficiency media are being developed to enable additional treatment of nitrogen and heavy metals.

Catalytic oxidation is a method of purifying water quality through sedimentation, adsorption, and digestion by microorganisms by passing river water and sewage through contact oxidation tanks filled with gravel, crushed stone, or various media. It is used for sewage treatment, and a diffuser is installed at the bottom of the contact oxidation tank to remove aeration and sludge.

The water purification device using the catalytic oxidation method is easy to maintain, has a large sludge retention in the tank, and has various biologics and is effective in removing substrates having low decomposition rate, while uniformly aeration of the media in the reactor. It is difficult to agitate, the aeration cost is relatively high, and the biomass generated in the media is determined by the load conditions, and the load conditions are limited due to the high risk of closing the media at high loads. .

The above facilities have the disadvantage that most of the contact media are buried underground, so it is difficult to replace them in the event of blockage of the media and that additional facilities such as rubber beams or intakes are required to prepare for the blockage of the media due to flooding. As it is formed in a straight shape, not only does it require a lot of site but also has a problem that most dissolved oxygen is consumed in the process of oxidative decomposition by microorganisms while passing through the catalytic oxidation channel. There is also a problem such that the processing efficiency of is not high, indicating a narrow processing efficiency.

In recent years, the method of purifying the water of the lake by using the natural environment to create a good condition for aquatic life and aquatic animals in the lake has been used, but its effect is still weak and the water quality improvement efficiency is inferior.

The present invention is to solve the problems described above, the purpose is to clean the water quality of the lake by using the natural ecosystem without creating artificial concrete construction, and at the same time purify the organic matter and phosphorus and It is to provide a lake water purification system to maintain a natural purification facility with excellent nitrogen treatment efficiency.

Another object of the present invention is to improve the water quality of the lake by forming a grassland in which aquatic plants and wetland plants are planted in the filtration tank, and to create a fish habitat where fish can live, and to make it a natural ecological tour or a park. It is to provide a water purification system for a lake that can be used as a natural learning place.

Another object of the present invention is to form a dam made of gravel and sand in the filtration tank and to form a slope on the upper part of the bank, so that the water of the lake goes through the filtration tank and the water generates the kinetic force according to the flow of the water to have the self-cleaning ability. At the same time, the dam made of gravel is heated by the outside temperature, and conducts heat to the water flowing to the upper part thereof, thereby providing a water purification system for the lake, in which the water is naturally activated by the physical change to perform the self-cleaning function.

In order to achieve the object, the present invention provides an inflow channel for installing water along the edge of the lake to allow the water in the lake to flow into the bank, and to increase the oxygen dissolved amount of the water introduced into the inflow channel. Aeration tank, sedimentation tank and sedimentation basin to separate suspended solids from the discharged water discharged from the specialty tank, and a sedimentation tank with filtration and sedimentation to prevent the passage of suspended solids in the center of the vortex adjustment basin and sedimentation basin; Large fish may live in the filtered water through the first filtration tank that filters the sludge and sludge first using aquatic plants, and the second filtration tank and second filtration tank which remove the nitrogen and artificial minerals from the filtered water using wetland plants. Small fish can inhabit the filtrate after the third and third filtration tanks with coarse stones at the bottom. Filtration tank 4, which has gravel on the bottom of the rock, filtrate which passed through the 4th filter tank, and the filtration tank on one side of the 5th filtration tank with gravel on the bottom and zigzag installed coarse rock on the top of it. It is characterized in that the filtered water is naturally discharged by forming a water level regulator with the same height as the level of the water.

Hereinafter, with reference to the accompanying drawings will be described in detail the water purification system of the lake according to the present invention.

1 is a plan view showing the overall configuration of the present invention with reference to the drawings, the water quality purification system of the lake of the present invention is installed in the lake (1) to maintain the natural state as it is to improve the water quality of the lake first An inflow channel 10 is formed at the edge of the lake 1 so that water in the lake flows in, and an aeration tank 20 is formed inside the inflow channel 10 to increase the oxygen dissolved amount in the water in the lake. One side of the sedimentation tank (30) is formed to separate the suspended substances contained in the water, one side of the sedimentation tank 30, the first, second, third, four, five, the filtration tank to sequentially filter the water (40) -80) is a composition that is sequentially formed.

As shown in FIG. 1, the inflow channel 10 removes the sedimentary layer formed at the bottom of the lake at the edge of the lake, and then moves the soil to form the embankment 11 along the edge of the lake 1 in the longitudinal direction. Water in the lake flows into the dike 11 to be sequentially filtered.

The inner end of the dike 11 is integrally formed with a machine chamber 21 having a plurality of pumps to blow air into the water introduced into the machine chamber 21 to sufficiently contact the water and the air to extinguish by oxidation and aerobic microorganisms. It is to promote the action, and to purify the water by removing the carbon dioxide, hydrogen sulfide, methane gas and the like to increase the oxygen dissolved amount, as shown in Figure 2 is formed intake port 22 for drawing water in the lake and intake On one side of the water inlet 22 is formed a drip tank 23 for storing the water flows into the upper portion of the drip tank 23, water above the water level of the drip tank 23 is automatically aeration chamber 24 A plurality of inlets (27) are formed to be introduced into the water) and the water introduced in the air is discharged from the aeration chamber 24 by a plurality of water pumps (not shown) formed in the upper portion of the intake port 22 and the water receiving tank 23. Generated and in contact with water It is good. The water that has passed through this series of water is stored in the granular opening 25 formed at one side of the aeration chamber 24, and when the water level of the granular opening 25 is exceeded, the drip tray 26 formed on the upper outer side of the granular opening 25 is formed. ) Through the hole (26a) formed in the upper part of the drip tray 26 to fall into the settling tank 30 to be described later. In this case, a plurality of inlets 27 are formed in the intake port 22, the water receiving tank 23, the aeration chamber 24, the standing mouth 25, and the drip tray 26 to sequentially move the water.

The sedimentation tank 30 forms the filtration calcification shaft 32 in the center of the vortex adjustment paper 31 and the clarification tank 33, where the vortex adjustment paper 31 has a predetermined depth (ideally, formed to a depth of about 3M). The discharged water discharged through the hole 26a of the drip tray 26 is formed to be lower than the height of the drip tray 26 to eliminate the vortices of the dripping water primarily in the vortex control pad 31 and maintain a stable state.

The fresh water in the vortex control paper 31 passes through the filtration stone shaft 32, wherein the filtration stone shaft 32 is formed slightly higher than the overall height of the vortex control paper 31, and the inclined surface becomes wider from the upper side to the lower side. Particles are precipitated in large stones and filled with gravel and sand to cause water flow in the water flow, so that water passing through the inside of the filtration limestone 32 is caused by water droplets and water flow. The water's kinetic power is such that it has a self-cleaning ability to collide with the gravel by the force of the water and to aggregate suspended matter contained in the water. decomposition. absorption. To clear the water. At this time, some of the suspended solids are precipitated in the sedimentation basin 33 while the water passes through the filtration shaft 32. The action that takes place at this time is the supply of pure oxygen and the pure water to make clear water from which suspended matter is first removed.

One side of the sedimentation basin 33, the first, second, third, fourth, fifth, filtration tank (40-80) is formed sequentially, the filtration tank (40-80) by mixing gravel and sand weir (41, 51, 61) And 71 and 81, and inclined surfaces 42, 52, 62, 72 and 82 tapered downward on top of the weirs 41-81. Here, the upper part of the banks (41-81) of the gravel is heated by the outside temperature of the sedimentation basin (33) passing through the bank (41-81), the heat is primarily conducted to the water, the sedimentation basin (33) When the water flowing from the inflow from the top of the bank 41 is introduced into the grass paper 43, the height difference is formed to form a slope 42 so as to perform the self-cleaning action occurs at this time, the slope 42 ) Is ideal to achieve a fall of 50 cm and a slope of 10 cm, depending on the situation.

Thus, the inflow water introduced into the first filtration tank 40 is primarily filtered due to the partial filtration and the flow of water while passing through the weir 41, and in this case, the water filter 43 is formed in the first filtration tank 40. The paper sheet 43 has a depth of 1-1.2m, and when the aquatic plants 44 are planted, various types of spaces are formed between the aquatic plants 44, which form habitats for fish and shellfish, and at the same time absorb harmful substances. As a result, the primary filtration is performed.

The second filtration tank (50) is formed in the same structure as the first filtration tank (40), the depth is 0.9m and the inside of the grassland 53, mainly among the wetland plants 54 (bileok, Bupyeongcho, reeds, etc.) Plant reeds to absorb underwater nitrogen, phosphorus and man-made minerals and to change the temperature of the water so that they can be made for fish and shellfish.

The third filtration tank 60 forms the same structure as the first and second filtration tanks 40 and 50 to form a depth of 1.2m of the fish habitat 63 and lays a large stone 64 on the bottom surface of a large meat. While using as a habitat is to filter the influent flowing through the filter tank (40, -60) sequentially.

The fourth filtration tank 70 has the same structure as that of the third filtration tank 60 while the depth of the fish habitat 73 is about 0.9 m, and the small particles are placed on the bottom of the soil to spread the gravel 74 and use it as a habitat for small meat. To filter.

The fifth filtration tank 80 forms the same structure as the first, second, third and fourth filtration tanks 40-70, and forms a shallow gravel pond 83 at a depth of 0.6 m and a gravel 84 on the bottom and a coarse rock. Zigzag (85) is installed to shake the flow of water so that the inflow water is self-cleaning and decomposes the last remaining sludge. And on one side of the gravel pegs (83) to form the level of the water level adjuster 86 at the same height as the high water level of the gravel pegs (83) sequentially the first, second, third, fourth, fifth, filtration tank (40-80) As a result, the coarse influent is naturally discharged. In addition, the water level adjuster 86 is to maintain a constant level even if the water level of the lake surface is lowered.

Hereinafter, the operating state of the water purification system of the lake according to the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 3, the dike 11 is removed from the edge of the lake 1 so that the water in the lake flows into the dike 11 to remove the sedimentary layer on the bottom surface of the lake 1. It is possible to increase the fresh water of the lake by forming the embankment (11) using the soil.

Experimental results show that the inflow channel 10 is ideally set as shown in Table 1 according to the freshwater capacity of the lake.

Water sequentially flowing in the inside of the machine room 21 of the aerated tank 20 in the lake introduced into the inflow channel 10 finally falls into the settling tank 30 through the hole 26a of the drip tray 26. The discharged discharged water is partially suspended in the sedimentation basin 33 while passing through the vortex control basin 31, the filtered sedimentary shaft 32, and the sedimentation basin 33.

Here, the water pump in the aeration tank 20 is to operate by installing about three,

While only one is used, the inflow canal 10 is operated once or twice a year about three times a year, causing artificial flooding to clean the inflow canal 10 and inhabiting the filtration tank 40-80. Animals and plants adapt to flooding, making habitat conditions stronger.

In this state, the inflow water passes through the gravel ponds 83 of the fifth filtration tank 80 while allowing the inflow water to undergo the self-cleaning process through the respective processes of the first, second, third, fourth and fifth filtration tanks 40-80. While the influent is finally filtered and becomes clear water, the water level is automatically adjusted by the water level regulator 86, which continuously circulates the influent filtered into the lake.

Here, the water level regulator 86 is to discharge the filtered filtered water while maintaining a constant water level even if the water level of the lake (1) surface is lowered.

The water purification system of the lake of the present invention constituted as described above removes the sedimentary layer formed on the bottom of the lake and installs a dike at the edge of the lake using this soil so that the water in the lake flows into the dike. Aeration tank, sedimentation tank, and 1st, 2nd, 3rd, 4th and 5th filtration tanks are formed in the channel so that the contaminated water of the lake can be purified while continuously circulating the water while maintaining the natural ecosystem. It will save money and restore natural ecosystems.

The present invention has the advantage that it can be used as a natural learning field for students as it can be constructed as a natural ecological tour or a park while purifying the water quality of the lake by constructing a natural purification system without constructing an artificial concrete structure.

The dams of the first, second, third, fourth, and fifth filtration tanks of the present invention are formed of gravel and sand, and the inflow water flowing into each filtration tank passes through the filtration tanks so that the water generates kinetic power and has a self-cleaning ability according to the flow of water. There is also an advantage to increase the filtration effect by forming a tapered inclined surface on the top.
