Abstract

end. The technical field to which the invention described in the claims belongs.

The present invention relates to a water purification method and apparatus for treating polluted water such as seas, lakes, rivers, etc. using moving objects, and in particular, any moving object or a traction device can be used, and It is possible to improve the treatment efficiency by segregating and untreated water, and to work even when wind, blue, turbulence, etc. occur.

I. The technical problem to be solved by the invention.

As a conventional treatment method, the use of a vessel equipped with all the facilities to apply the pressure floating method on the hull required the enlargement of the vessel, and lacked maneuverability, which was unsuitable for the treatment of a wide range of waters. Forming a floating underwater structure between ships or forming an underwater structure at the bottom of the ship by using the can be purified at the current position of the water to be treated without requiring a separate reaction tank, but the former must be two or more Ship group should be used, the latter had a problem in the limitation of the treatment area according to the size of the ship.

In addition, when turbulence is formed in the water to be treated due to the vessels and winds being moved, bubbles are detached from the aggregates (scums) floating by the microbubbles so that some of the scums do not disappear, and scums move in the opposite direction to be removed. In addition, there is a difficulty in collecting scum because the surface of water is not kept horizontal, and in the lower part that is not affected by the underwater structure, the treated water and untreated water are mixed, thereby reducing the treatment efficiency in terms of reaction rate, especially during rain. Due to the phenomenon that the scum does not go away as bubbles are combined with the floc, there is also a problem that can not be purified.

All. Summary of the Solution of the Invention.

A floating reactor structure in which the compartments are divided up to the deep bottom of the water to be treated is formed, and a pressurized water and a chemical injector are put in the reactor structure to perform water purification by pressurization. By removing any limitations of the treatment area by the moving body by removing the limitation of the treatment area by moving the reactor structure by moving the reactor structure by using any moving object or towing means operating on land, sea, or air in the form of continuous flow In terms of efficiency, the treatment efficiency is increased.

In addition, by forming a cover in the field reactor structure to enable normal operation even during rainfall, and to form a device to induce the flow direction of the floating material in the reactor structure to enhance the removal efficiency of the floating material.

la. Important use of the invention.

On-site water purification in artificial and natural waters such as seas, dams, rivers, reservoirs, lakes and rivers.

Description

A purification method of a water guality and an installment considered a motion of fluid and bad weather in an area Considering a motion of fluid and bad weather in an area, including water, dams, rivers, reservoirs, lakes, and rivers such as the sea, dams rivers and lakes}

The present invention relates to a water purification device that can be used to process the contaminated water, such as the sea, lakes, rivers, etc. by using a moving object, in particular, any moving object or traction device can be used, By dividing the compartment to the bottom to improve the treatment efficiency, it is possible to work not only when turbulence occurs due to the effects of waves, waves, wind, tidal currents, etc., but also in rainy weather.

Conventionally, a vessel equipped with all facilities for applying the pressure flotation method such as flocculant chemical tank, flocculation tank, flotation tank, etc. in the treatment of algae or pollutants that grow excessively in the sea, lake, river, etc. In the water system to be treated, the water to be treated was lifted up to the hull for treatment, but a separate reactor was needed to treat the water drawn up. It was not suitable for the treatment.

In order to solve this problem, a separate reaction tank is formed by forming a floating underwater structure between two vessels each having a driving device necessary for water purification and facilities for removing floating substances generated after treatment. There is a need to purify the water at the current location of the water to be treated, but there is a disadvantage that more than one ship is required.

In addition, by installing only the necessary equipment on the hull and forming a floating underwater structure on the lower part of the ship, it is possible to purify the water using one ship instead of the ship group, but only within the area of the underwater structure formed of the ship. Therefore, there was a limitation in the treatment capacity, so the size of the vessel was essential for the treatment of a wide range of waters.

Therefore, in order to purify a wide range of water by the above-mentioned method, a large-scale ship facility is required, and when the wind blows or waves or waves due to wind or large ship movements, turbulent water is formed in the water to be treated and the scum ( scum) again, or the moisture content of the recovered scum is increased, especially when the rain drops fall during rainfall, the scum that floats on the surface of the floc and bubbles are separated again and settled again If the removal of the work itself is difficult to occur, there is a problem that can not be cleaned.

In addition, there is a problem in that the reaction efficiency is kept low in terms of reaction rate in the deep water without the influence of the underwater structure because it operates in a form similar to the complete mixing reactor in which the treated water and untreated water are mixed.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to eliminate the limitation of the treatment area by the moving body, and to increase the treatment efficiency in terms of reaction rate and scum removal efficiency of the flocculated aggregates. It is intended to enable the normal operation under the same treatment efficiency under any conditions such as fluid behavior such as wind, rainfall, tidal currents, waves and waves, turbulence, or bad weather.

For this purpose, a flotation structure is formed on the water surface of the treated water so as to extend to the bottom of the treated water in parallel to both sides to form a floating structure to separate the treated and untreated water into the deep water, The reaction tank using a moving object or a traction device that is operated in land, sea, or air as a driving means in a state in which pressurized water and a chemical injection device are put into the reactor structure to perform water purification work by a pressure flotation method. While moving the structure, the entire body of water can be treated in the form of a plug flow reactor.

In addition, by forming a cover in the reactor structure to enable normal operation even during rainfall, and to form a device for inducing the flow direction of the floating material in the reactor structure to enhance the scum removal efficiency.

The present invention by spraying the pressurized water containing the flocculant and air into the water to be treated using a moving body and a traction device at a high pressure to agglomerate contaminants contained in the water by the flocculant and at the same time In the field water purification method using the on-site pressurization method to float to the surface, the floating reactor structure floats on the water surface in a certain area of the water to be treated and separates the treated and untreated water into the deep water. The floating reactor structure (1) is installed in a state in which (1) is installed and the pressurized water and the chemical injection device (2) are put into the floating structure (1) to allow the water purification operation by the pressure floating method. The continuous flow formula moves through the whole body of water by using any moving object (3) driven on land, sea, or air as a driving means. plug flow) The operation of the reactor is to purify the water.

Hereinafter, the water purification method and apparatus of the present invention will be described in more detail with reference to the following examples.

1 and 2 show an embodiment of the purification operation using the water purifying operation of the present invention or the traction device 3 as a drive means that is operated at sea, the moving body 3 is a motor boat, a ship, etc. It is possible to drive any type of drive on the sea, and any conventional traction device on land.

First, the partition wall 12 which can extend to the bottom of the treatment water under the frame 11 attached to the floating body 11a on the surface of the water to be treated in the sea, lake, river, etc. (12a) is installed parallel to both sides to separate the treated water and untreated water into the deep water, and the floating material collection device 13 is formed at the end between the partition 12 (12a) And on the other side, a floating reactor structure (1) having a connecting device (14) formed thereon with a movable body (2), and pressurizing the water to purify the water by the buoyancy method within the float reactor structure (1). Water purification operation is performed by connecting the floating reactor structure (1) to the moving body (3) while the water and chemical injector (2) is put into the moving body (3) while moving the whole water. To be done It is.

At this time, the pressurized water and the chemical injector 2 are fixed to the frame 11 of the floating reactor structure 1, or by installing an auxiliary frame (11b) that crosses between the partition wall (12) (12a) auxiliary frame By fixing to (11b) it should always be located in the floating reactor structure (1), the auxiliary equipment for supplying pressurized water and chemicals is to be mounted to the moving body (2) to proceed with the work.

At this time, when the area of the water to be treated such as a small pond or lake is narrow, it is possible to carry out work by attaching it to the land adjacent to the water to be treated.

At this time, the auxiliary equipment to be prepared for the pressurized water and chemical injection, the chemical tank for storing the flocculated drug, the chemical pump for supplying the chemical stored in the chemical tank to the chemical injection device, pressurized water or treated water A pressurized pump for supplying the tank, a compressor for supplying compressed air to the pressurized tank, a pressurized tank for storing pressurized water mixed and dissolved by the water supplied by the pressurized pump and the compressed air by the compressor; Power supply.

In addition, the pressurized water and the chemical injector (2) is to be installed in multiple stages according to the depth as shown in Figure 5 to enable a pressurized flotation method of the multi-stage injection method for each depth, at this time pressurized water and chemicals installed for each depth The size and injection pressure of the injection nozzle 21 of the injection device 2 should be different.

In other words, by varying the injection pressure or the size of the nozzle in consideration of the depth of the injection nozzle 21 is located, the size of the bubbles injected from the deep and surface layers are similarly adjusted to enhance the reaction efficiency and to effectively purify the water quality will be.

This is because when the nozzles of the same specification are used, the deeper the position of the nozzle, the smaller the bubble size.

For example, since the size of the bubble injected at a depth of 10 m is only 1/2 of the size of the bubble injected from the surface layer, it takes a lot of time for the sludge to float, and the hydration reaction of the flocculant or the formation of the aggregate is already completed. This is because contaminants in the upper layer are not effectively removed.

In addition, the position of the injection nozzle installed in multiple stages of the floating material (10a) is moved by the pressurized water is sprayed horizontally through the first spray nozzle (21a) from the first injection nozzle (21a) to the deepest point of view The second spray nozzle 21b is installed at the position, and the third spray nozzle 21c is installed at the position of the floating material 10b moved by the pressurized water sprayed horizontally through the second spray nozzle 21b. By installing several injection nozzles in this manner, the flocculation and flotation efficiency of contaminants can be improved, and the sludge floats in a relatively constant area so that the sludge can be stably and effectively removed.

At this time, the floating material 10a, 10b generated by generating wind power of the blower 18 for guiding the moving direction of the floating material 10a, 10b into the treatment region of the floating reaction vessel structure 1 is lifted. The material collecting device 13 can be easily gathered and at the same time prevent the diffusion of the floating material (10a) (10b) by turbulence.

In this case, the floating material collection device 13 is described as being formed only at one end between the partitions 12 and 12a, but is installed on both sides even when the flow direction or the wind direction is changed in the treated water. In addition to preventing the spread of floating material, it can also be collected.

In addition, the flotation material collection device 13 is to form the inlet (13a) of the flotation material to be concave (凹入) to prevent the natural outflow of the inlet flotation material, the collection portion (13b) of the flotation material It is to be formed so that the flow can be freely cope with the direction of movement of the floating reactor structure (1).

On the other hand, the frame 11 forming the floating reaction vessel structure (1) uses a light and water-resistant, strong acid-resistant pipe or tube, using a foam material, or blow air into the airtight container of a plastic material to rise above the water surface The bulkhead 12 and 12a may be formed of a fiber, a sheet, or a plate of a material having water, acid, and abrasion resistance. It should be possible to adjust the width according to the adjustment and the width of the water. For this purpose, various connection means such as zippers, straps, and linkages can be formed to allow infinite extension or shortening of the length or width, so that it can be used in wide and deep waters. Not only should it be possible, but also it can be easily installed and transported. The stationary body 15 is formed so that it may not flow even by the flow of water flow by turbulence or the like.

At this time, if a plurality of partitions 12 and 12a are installed to allow a plurality of reaction zones 1a formed in the floating reactor structure 1 to be formed in parallel, a large area of water can be treated in a short time.

In addition, the fixture 15 is to be made of an object having a weight such that the buoyancy acting by the frame 11 is not canceled while not being flown even by the flow of the water flow.

In addition, as shown in Figure 3 on the upper portion of the frame 11 by connecting a plate or rod of plastic or wood material to form a worktable 20 made of a width that can be walked by a worker to enable simple work or As shown in FIG. 4, the installation facility 16 may be formed to allow the operation at the same time as the installation facility 16a for pressurized water and chemical injection.

In addition, by forming a cover 17 to block the entire upper portion of the frame 11 to prevent rain water from entering the area being processed during rain to prevent the breakage of aggregates generated in normal rain water purification The cover 17 may cover the top of the frame 11 of the floating reactor structure 1 using a sheet of water resistant and acid resistant material or support on the top of the frame 11. Alternatively, by forming a separate support structure 19, such as a support rod, by coupling the corners of the sheet to the upper portion of the structure 19 to be fixed, and also to the work table 20 or the attachment mounting unit 16 It can be formed by extending the entire upper portion of the frame (11).

The water purification method of the present invention carried out as described above is capable of driving the moving body 3 on land such as a car or a truck, or using any kind of moving body 3 capable of driving in the air. It can be done.

Therefore, the water purification operation according to the present invention installs the floating reactor structure 1 in a predetermined region of the treated water body to isolate the treated water and the untreated water from the deep bottom portion of the treated water, so as not to mix the inside of the floating reaction tank structure 1. With pressurized water and chemical injector (2) for carrying out water purification work by pressurized flotation method, it is connected to any kind of movable body (3) driven on land, sea, and air to the movable body (3). It is possible to purify the water in the form of a continuous flow reactor through the entire body of water by the driving force.

Therefore, according to the water purification method of the present invention, the entire body of water to be treated is operated in a form similar to that of a fully mixed reactor in a form similar to a pluf flow reactor, thereby treating efficiency in terms of reaction rate. It is possible to increase much more, and also to exclude the limitation of the selection of the moving body and the processing area according to the moving body, and the efficiency of removing the aggregates is excellent, and the treatment efficiency can be increased in terms of the removal efficiency of the aggregates.

In particular, the problem of having to stop or turn on work due to rain or wind waves by allowing normal work to be possible even in bad weather such as wind or rainfall, and the behavior of fluids affecting work such as blue waves, waves, and tidal currents. It can be solved completely.
