Abstract

PURPOSE: A method for purifying fresh water uses mineral matter and aquatic plant to purify sludge which is precipitated at the bottom of lake or reservoir. CONSTITUTION: Wastewater flows into the purification system through a pipe(104) which is installed at the bottom of lake or reservoir. The pipe(104) is connected to a storage tank(106). A first moving hole(122) is located at the inside of the storage tank(106), and an outlet(130) for discharging sludge is connected. A first storage tank(114a) is installed at the side of the storage tank(106), and a second hole(123) is located between the storage tank(106) and the first storage tank(114a). A storage tank(108) is filled with gravel layer(132), germanium stone layer(133), and zeolite layer(134). Plants which have function for purifying water are raised on the zeolite layer(134). The precipitated sludge is purified by mineral matter and plants naturally.

Description

Fresh Water Purification System

The present invention relates to a water purification system of fresh water, and in particular, using fresh water and minerals, fresh water for purifying sewage, including sludge settled at the bottom of artificially formed fresh water such as ponds and reservoirs, and then desalting it again. It relates to a water purification system.

Generally, parks, golf courses, and amusement parks have artificially constructed freshwater ponds, such as ponds and tides, for the purpose of landscaping. The fresh water is circulated for a long time without water circulation, and green algae are easily generated and cause bad smell. In other words, when nutrients such as nitrogen or phosphorus generated from freshwater such as ponds or reservoirs are introduced, eutrophication of freshwater where phytoplankton is abnormally proliferated is promoted, resulting in freshwater algae and red tide. Therefore, when oxygen deficiency occurs in the lower part of fresh water, odors and turbidity occur, BOD / BOC increases, water acidification and foaming occur, and fish, etc. cause collective death of fish due to these causes.

In order to improve the quality of the freshwater, the freshwater was purified by adding chemical coagulants and aluminum sulfate. The use of chemicals to clean freshwater has many environmental problems, and there is a risk that natural ecosystems can be destroyed if continuously introduced.

The present invention has been invented to solve the above problems, the sewage, including sludge precipitated in the lower part of the fresh water, such as ponds, reservoirs are stacked in the septic tank in which minerals are stacked and aquatic plants are planted and purified naturally again By desalination, the aim is to provide a fresh water purification system without environmental problems such as destruction of natural ecosystems.

The detailed operation of the fresh water purification system according to the present invention configured as described above is as follows.

In the water purification system according to the present invention, as shown in FIG. 1, the reservoir 106 is a device such as a motor (not shown) for filthy water including sludge through a sewage inflow pipe 104 embedded in a lower portion of the freshwater reservoir 102. By inflow. When the sewage is filled in the reservoir 106, the sewage stored in the reservoir 106 flows into the first reservoir 114a through the first moving hole 122. The first reservoir 114a receives the sewage stored in the storage tank 106 through the first moving hole 122 installed in the lower portion and discharges the sewage to the upper portion of the first septic tank 108 through the second moving hole 123. do.

In the first septic tank 108, the gravel layer 132, the ganban rock layer 133, and the zeolite layer 134 are stacked in order from the bottom, and the zeolite layer 134 has aquatic plants such as reeds, water hyacinths, and buds having excellent water purification functions. Since (136) has a planted structure, water purification by reeds, water hyacinths, and buds, as well as minerals such as zeolites and elvans, which promote the aerobic microbial habitat, doubles the purification capacity. In other words, zeolite has a very high basic substitution ability (CEC), has an excellent effect of neutralizing acidity, and has a large amount of micropores, thus creating an effective weather and providing a space for soil microorganisms to easily inhabit. Perform.

The first septic tank 108 naturally purifies the introduced sewage by aquatic plants and minerals, and discharges the sewage to the second reservoir 114b through the third moving hole 124 installed at the lower portion. The second reservoir 114b receives and stores the purified wastewater from the first septic tank 108 and discharges the wastewater to the upper portion of the second septic tank 110 through the fourth moving hole 125. Since the second septic tank 110 also has the same structure as the first septic tank 108, it naturally purifies the sewage introduced by the aquatic plants and minerals. In addition, the water purified by the second septic tank 110 is The third storage tank 114c flows into and is stored in the third reservoir 114c through the fifth movement hole 126 installed at the lower portion of the 110, and the sixth movement hole 127 of the third purification tank 112 is disposed in the third reservoir 114c. It will flow to the top. That is, the fresh water purification system according to the present invention is configured such that filthy water flows from the first septic tank 108 to the third septic tank 112 to the upper portion of the septic tank at the rear end from the lower septic tank. In other words, water purification is performed by repeatedly installing a septic tank that can naturally purify sewage by aquatic plants and minerals, and having a structure that allows the water to flow back to each septic tank to remove suspended nutrients and organic matter in the water. .

The water purified through the third septic tank 112 is moved to and stored in the fourth reservoir 114c provided on the side of the third septic tank 112. The water stored in the fourth reservoir 114c is again sent to the fresh water by the sending pipe 160 installed on the side by an underwater pump (not shown).

To remove the precipitate. In addition, the center of the lower portion of each tank is connected to the sludge discharge pipe 130 to discharge the sludge and the like moved to the lower by weight. In addition, each tank is provided with an oxygen supply (not shown) to artificially draw oxygen into the water To provide good conditions for aerobic bacteria to live.

As described above, in the present invention, sewage, including sludge precipitated in the lower part of fresh water, such as ponds and reservoirs, is deposited by a septic tank in which minerals are stacked and aquatic plants are planted, and then naturally purified and then desalted, thereby destroying natural ecosystems. There is an effect that does not cause environmental problems.

Although the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited thereto and may be improved or modified by those skilled in the art within the scope of the technical idea of the present invention. In the present invention, the number of septic tanks may be increased or decreased as necessary.
