Description

Simplified purification device to remove nutrient salts and organic matter that inflow into streamlet and tributary and cause algal bloom}

The present invention relates to a simple purification device for removing green algae-generating nutrient salts and organic substances flowing into a stream and a tributary, and more specifically, before introducing the nutrient salts and organic substances that cause green algae into the river. It is a device for removing at a stage and for efficiently removing the same, and it relates to a simple purification device for removing green algae-generated nutrients and organic substances flowing into small and tributaries that can be easily installed.

Recently, due to the occurrence of a global abnormal climate and various livestock facilities and various development projects located around the river, the green algae phenomenon has emerged as a major problem.

Green algae refers to a phenomenon in which blue-green algae grow excessively in rivers such as rivers and lakes, and the color of water changes to dark green.

Green algae can cause odors and cause discomfort, and can cause harmful effects when toxic substances are released and consumed.

In addition, when green algae occur in a wide area, sunlight that can be introduced into the water is blocked and dissolved oxygen is not introduced, causing destruction of the aquatic ecosystem, and consequently, destroying the environment of the entire river.

In particular, since most of these rivers are provided for drinking water of each household in the form of tap water, social attention is focused on a solution to this, and many solutions have been proposed.

As a solution, a method of suppressing the occurrence of green algae or a method of effectively removing the green algae is common.

As a method of suppressing the occurrence of green algae, there is a method of minimizing the influx of nutrient salts or organic substances that are the cause of green algae, or promoting the self-cleaning operation by forcing the circulation of water, and removing the causative material using additives. Is presented.

As a method of effectively removing the generated green algae, a method of biochemically adding a material that binds to the green algae, or a method of physically removing the green algae by means of a device is proposed.

However, the facilities installed to block the influx of causative substances cannot be applied at the right place due to the cost problem caused by the installation or maintenance, and are applied only to some large inflow destinations, so they are applied to small flows or tributaries. There is a problem that the causative material flowing from (支流) cannot be blocked at all.

Also, the physical removal method is not a fundamental solution since it is about treatment after the occurrence of green algae and the adverse effect accordingly.

The present invention was invented to solve the above problems, it is possible to simply install at the outlet of the stream or tributary, intentionally causing the occurrence of green algae before entering the stream to induce exhaustion of the causative material, and the green algae The object of the present invention is to provide a simple purification device for removing green algae-generated nutrient salts and organic substances flowing into small and branch streams that suppress the occurrence of green algae in the entire river by removing the material in advance and allowing it to flow into the stream.

The object of the present invention is not limited to the above-mentioned object, and other objects not mentioned will be clearly understood from the following description.

In order to achieve the above object, a simple purification device for removing green algae-generated nutrients and organic substances flowing into a stream and a branch according to the present invention is a purification device installed in a sewage discharge port flowing into a stream and a branch, wherein the purification device is , It is installed on the lower portion of the sewage discharge port, the lower part of the sewage discharge port is formed of a spiral partition wall arranged to be the center, causing the stagnation of sewage to generate green algae; green algae generating means; And at the end of the spiral partition wall of the green algae generating means It is installed, and it is characterized in that the green algae comprises a collection means for collecting green algae contained in the discharged water from the means.

In addition, the collecting means is characterized in that it consists of an upper layer portion for collecting floating green algae and a lower layer portion for collecting sedimentary green algae.

In addition, the center of the green algae generating means is characterized in that the distribution means is further provided so that the falling sewage is evenly distributed on the bottom surface of the green algae generating means.

In addition, the distribution means, the rotating shaft portion; and the rotating shaft portion has a cap (cap) shape to be fitted to the center, the outer surface is characterized in that it is made of a body portion with wings.

In addition, the wing is characterized in that it is configured in a helical (helical) shape on the outer surface of the body portion.

The present invention by the above configuration can be expected the following effects.

By inducing the occurrence of green algae in advance, the nutrient salts and organic substances, which are the causative substances, can minimize the amount of the causal substances being exhausted before being introduced into the river, and thus flowing into the river.

As described above, there are many cases where facilities for removing the causative material are not properly provided in the sorting or branching due to cost problems, maintenance problems due to large-scale or mechanization, but the present invention enables simple installation and complicated configuration. Because it is not a mechanical device, maintenance is very simple and can be installed at any outlet for inflow into the river.

In addition, causative substances such as nutrient salts and organic substances are microscopic substances, so it is practically difficult to filter them unless green algae is used or a separate additive is used. By generating it, it can be exhausted to prevent inflow into a river that can be used as drinking water.

In this way, by exhausting the causative substances before entering the river, by minimizing the causative substances flowing into the river, the possibility of green algae in the river can be very low.

The installation of the present invention, which is configured in a simple form, reduces the cost of installation or maintenance compared to the conventional solution, and also reduces the possibility of green algae in the river, thereby reducing the cost of handling it. As a result, ultimately, the waste of social costs can be prevented by the present invention.

As the possibility of occurrence of green algae in the river is lowered, an additional disinfection step taken to supply it to tap water can be eliminated, and it is possible to prevent an adverse effect that may occur in the drinking body.

By generating green algae, floating green algae and sedimentary green algae are selectively collected to facilitate removal of the captured green algae.

Additionally, another utilization method using the removed green algae may be devised, for example, it may be possible to use the green algae as fertilizer for clearing the land.

Hereinafter, with reference to the accompanying drawings, a simple purification device for removing green algae-generated nutrients and organic substances flowing into small and tributary according to a preferred embodiment of the present invention will be described.

1 is an overall configuration diagram of a simple purification apparatus for removing green algae-generated nutrients and organic substances flowing into a stream and a branch according to a preferred embodiment of the present invention, and FIG. 2 is a stream and a branch according to another embodiment of the present invention The overall configuration of the simple purification device for removing nutrients and organic substances generated by green algae and FIG. 3 is a configuration diagram of two distribution means according to an exemplary embodiment of the present invention.

A simple purification apparatus for removing green algae-generating nutrients and organic substances flowing into small and branch streams according to a preferred embodiment of the present invention is a green algae generating means 100, a collecting means 200 and a distribution means as shown in FIG. It consists of 300.

For ease of explanation, the upper part will be described as the upper part, the lower part, and the left and right sides as the side.

Each stream has a number of sewage outlets 10 through which sewage from a nearby factory, livestock complex or housing complex flows.

In general, the sewage is formed to flow in the direction of the river along the pipe-shaped drain pipe buried underground, and the end of the drain pipe is formed of a free end so that the sewage flows directly into the stream.

The present invention may be separately installed in the sewage outlet 10 to remove nutrients and organic substances, which are the causative agents causing green algae flowing into the river.

First, look at the green algae generating means (100).

The green algae generating means 100 may be formed under the free end of the sewage outlet 10, and may artificially induce the stagnation of sewage to generate green algae.

In general, as a solution to the existing green algae, a method of quickly removing the green algae or a method of removing the causative agent by adding an additive was used, but as described above, this is only a follow-up action after the occurrence of green algae or It could cause additional economic and environmental adverse effects due to the addition of additional additives.

The present invention is due to the provision of the green algae generating means 100, by intentionally generating green algae in the step before the sewage flows into the river, so that the nutrients and organic substances that cause the green algae are exhausted, generated The technical point is that only the sewage from which the green algae has been removed flows into the river, and the green algae generating means 100 plays a key role.

Green algae generating means 100 may be formed of a spiral partition wall 110, the center of the spiral is located in the lower center of the sewage discharge port 10, the sewage discharged from the sewage discharge port 10 and the present invention It can be the first contact point.

Green algae generating means 100 is formed of a spiral partition wall 110 as described above, the upper surface may be configured in an open form.

Since the present invention is to intentionally generate green algae in the green algae generating means 100, the sewage located in the green algae generating means 100 may have an open upper surface so that photosynthesis is effected by the inflow of light energy.

Additionally, the upper surface except for the center may be closed with a partition wall of a transparent material such as an acrylic plate so that the sewage inside does not flow into the river before the green algae occurs due to the inflow of rainwater.

The green algae generating means 100 may be formed of any material, and since contact with sewage occurs continuously, it is preferable to be formed of a stainless material or a concrete material in consideration of the rust phenomenon.

The width, the total length and the curvature of the physical properties of the spiral partition wall 110 may be variably applied according to the amount of sewage discharged from the sewage discharge port 10.

When the amount of sewage discharged from the sewage outlet 10 is large, by increasing the width, length, and curvature of the spiral partition wall 110, the flow of sewage can be delayed so that green algae is generated in the green algae generating means 100, , If the amount of sewage is small, the objective can be achieved even if the physical properties of the spiral partition wall 110 are relatively small, so that the size of the green algae generating means 100 can be adjusted in consideration of the installation place and cost.

In the above-described embodiment, the green algae generating means 100 was defined as a spiral partition wall 110, but it is also possible to use a square or other shape in which the flow of sewage is delayed. However, considering the smooth flow of sewage, it may be most preferable to be configured in a spiral.

A distribution means 300 may be provided at the center of the green algae generating means 100, and detailed description will be described later.

Next, look at the collecting means (200).

The collecting means 200 is installed at the end of the spiral partition wall 110 of the green algae generating means 100, and may serve to collect green algae contained in the discharged water discharged from the green algae generating means 100.

As described above, the introduced sewage is green algae generated by the action of light energy, nutrient salts and organic materials of the sewage from the green algae generating means 100, and the green algae generated sewage is generated from the green algae generating means 100. It flows to the distal end along the helical partition 110 to be discharged.

The collecting means 200 is provided in the form of a net at the distal end of the helical partition 110, so that the green algae can be physically separated from the discharge water.

The collecting means 200 is provided to be detachable by a user, so that when the green algae are collected above the acceptable value in the collecting means 200, the green algae can be removed and reattached after removing the green algae.

The collecting means 200 may be provided as being divided into an upper layer portion 210 and a lower layer portion 230.

The green algae may be composed of a floating green algae present at the top of the sewage and a sedimentary green algae present at the inside or the bottom of the sewage. Since the floating green algae and the sedimentary green algae do not occur at the same ratio, the green algae It can be collected intensively on one side.

In this case, without removing the entire collection means 200, only one of the upper layer 210 or the lower layer 230 is selectively removed to remove the green algae, thereby quickly recovering the function.

The collecting means 200 is preferably installed at the end of the helical partition 110 of the green algae generating means 100, but additionally, it may be installed in the middle of the helical partition 110, or may be installed in a plurality of middle and end ends. It may be possible to further increase the collecting capacity of the collecting means 200.

Next, look at the distribution means (300).

The distribution means 300 may be installed at the center of the green algae generating means 100.

Sewage may be viscous as a liquid containing nutrient salts and organic substances, and when sewage is intensively added to one side of the bottom surface of the green algae generating means 100, generation of green algae due to interaction with light energy is not smoothly performed. It may not.

Therefore, it is necessary to ensure that the sewage flowing from the sewage discharge port 10 is evenly distributed on the bottom surface of the green algae generating means 100, and the distribution means 300 may be provided to effectively achieve this function.

Distribution means 300 may be made of a rotating shaft 310 and the body 330.

The rotating shaft 310 may be provided in a shape protruding from the center of the green algae generating means 100 to the upper side, and is preferably formed of a cylindrical rod.

The rotating shaft portion 310 is located at the center of the body portion 330, which will be described later, and may serve to support the body portion 330 when rotating around the rotating shaft portion 310.

The body part 330 has a hole in the center where the rotating shaft part 310 can be inserted, and thus may have a cap shape to be coupled to the upper portion of the rotating shaft part 310.

Since the body portion 330 is a portion that is impacted by falling sewage, wear may occur due to continuous impact, so that only the body portion 330 except the rotating shaft portion 310 is easily replaced, and the body portion This is to facilitate rotation of the 330.

Rotation of the body portion 330 may serve to radiate the sewage evenly while the body portion 330 rotates by the inflow of sewage. In order for the body portion 330 to rotate easily, a bearing, etc. may be used between the rotating shaft portion 310 and the body portion 330, so a detailed description thereof will be omitted.

A screw wing 331 formed in a helical shape may be provided on the outer circumferential surface of the body portion 330. Screw wing 331 may be a shape protruding from the outer surface embossed, collectively all of the shapes formed in the body portion 330 to make the sewage flow in a helical direction, such as a shape engraved on the outer peripheral surface of the body portion 330 It may be.

Since the falling sewage falls in the direction of gravity, the screw blades 331 formed on the outer surface of the body part 330 induce the twisting of the body part 330 by rotating the direction of the falling sewage from the vertical direction. It acts to cause, and the driving force generated by the discharged sewage can cause the rotation of the body portion 330 to be stronger.

Due to this action, the falling sewage can be distributed to a point farther from the center, and by increasing the contact area with light energy, generation of green algae can be made more smoothly.

Based on the above-described configuration, look at the method of operation of the present invention.

The sewage discharged from the existing sewage discharge port 10 falls to the upper portion of the distribution means 300 located at the center of the green algae generating means 100 formed at the bottom.

The distribution means 300 is provided with a body portion on which the screw blade 331 is formed on the outer surface. When the sewage falling in the vertical direction flows along the screw blade 331 of the body portion 330, it goes out in the vertical direction. Sewage flows in the direction, which causes the rotation of the body portion 330.

The rotation of the body portion 330 obtains the driving force due to the reaction with the discharged sewage, so that rotation can occur more strongly.

Due to this action, the falling sewage can be evenly and widely distributed radially on the bottom surface of the green algae generating means 100.

The discharged sewage flows along the spiral partition wall 110, which is the shape of the green algae generating means 100. Due to the shape of the green algae generating means 100, the flow is delayed and flows in time.

Light energy supplied to the upper part of the green algae generating means 100 reacts with nutrients and organic substances contained in the sewage flowing inside the green algae generating means 100, so that the green water is generated green algae, and the present invention provides such green algae. The occurrence is intended to occur intentionally inside the device.

Sewage with green algae is introduced into the collecting means 200, and floating green algae are physically brought into the upper layer 210 of the collecting means 200 and sedimentary green algae are physically by the lower layer 230 of the collecting means 200. Will be captured. In addition, nutrients and organic substances that are not exhausted due to the occurrence of green algae can also be collected and removed.

The user removes the green algae collected in the collecting means 200 and removes the green means 200, and selectively removes the upper and lower parts 210 and 230 to remove the green algae and reattach the green algae.

Since green algae cause exhaustion of nutrients and organic substances in the sewage, nutrients and organic substances are minimized in the sewage from which the green algae has been removed.

The sewage from which the green algae has been removed is finally discharged to the stream, and since nutrients and organic substances are minimized, the possibility of green algae in the stream can be reduced.

The above-described embodiments are merely exemplary, and those skilled in the art can variously modify various embodiments therefrom.

Therefore, the true technical protection scope of the present invention should include other embodiments variously modified as well as the above embodiments by the technical spirit of the invention described in the following claims.
