Description

The present invention relates to an ammonia single-stage degassing device and a water treatment method using the same. More specifically, it can effectively remove ammonia and organic substances contained in sewage water using hypochlorous acid-based chemicals, and forms bubbles in sewage water to form wastewater and hypochlorous acid. This relates to an ammonia single-axis degassing device that can maximize the effect of a strong degassing reaction while allowing rapid mixing of chemical products and a water treatment method using the same.

In general, ammonia in wastewater is a representative pollutant. If not thoroughly purified, eutrophication (green algae) occurs in rivers and foul odors occur in wastewater treatment plants. In addition, ammonia consumes dissolved oxygen (DO, Dissolved Oxyge) contained in water, creating an anaerobic state and acting as a poison to fish.

In addition, the nitrogen component in the wastewater is converted to ammonia through a wastewater treatment facility and then treated through nitrification and denitrification processes. However, there is a problem that a lot of energy and resources are input during the treatment process. As of 2019, the amount of electricity used in domestic wastewater treatment facilities amounts to 3,650 GWh. This usage corresponds to 0.7% of the total electricity supplied domestically (520,499 GWh), and the electricity used to remove nitrogen from water such as ammonia amounts to about 30%.

Conventionally, microorganisms, reverse osmosis, or ammonia degassing were used to remove ammonia contained in wastewater. Here, when using nitrifying microorganisms or anammox microorganisms, a long residence time of usually 12 to 48 hours is required, so there is a problem that the scale of the wastewater treatment facility becomes enormous in order to treat the required amount of wastewater treatment.

In addition, when using the physical method of reverse osmosis (RO), it is possible to remove more than 90% of ammonia contained in wastewater, but there is a problem in that membrane filtration requires enormous replacement costs due to power costs and lifespan, and ammonia When using the degassing method, the treatment efficiency is low compared to the cost of the chemical input, so it is not widely used.

The ammonia single-axis degassing device 100 according to a preferred embodiment of the present invention has a structure in which wastewater and hypochlorous acid-based chemicals are rapidly stirred, effectively removing ammonia contained in wastewater within a short period of time (for example, 1 to 2 hours). It is a water treatment device that can be removed, thereby significantly reducing the power used for water treatment, and increasing the water treatment amount to reduce the size of the device. As shown in Figure 1, the high-speed flocculation module 200 and the non-powered plug Together with the flocculation module 300 and the multi-diaphragm floating separation module 400, a water treatment system can be formed that sequentially removes suspended solids, ammonia, and organic matter contained in wastewater.

The ammonia single-axis degassing device 100 removes ammonia and organic matter contained in wastewater that has been pretreated to remove suspended solids by the high-speed coagulation module 200, the non-powered flocculation module 300, and the multi-stage partition-type flotation separation module 400. To this end, as shown in FIGS. 1 and 2, a water treatment chamber 110 and a chemical supply unit 140 are included.

First, the water treatment chamber 110 is a storage tank that provides space for removing ammonia and organic matter contained in wastewater, respectively. A watertight inner space is formed and a partition wall 111 extends upward from the bottom of the inner space. It is divided into an ammonia single-axis degassing tank 120 and an organic matter oxidation tank 130.

Here, a wastewater inlet 121 through which wastewater is supplied is formed in the ammonia single-axis degassing tank 120, and a treated water outlet 131 through which treated wastewater is discharged is formed in the organic matter oxidation tank 130.

In addition, the partition wall 111 can prevent wastewater in which ammonia has not yet been degassed from the ammonia single-axis degassing tank 120 from flowing into the organic matter oxidation tank 130, and the second partition wall 123, which will be described later, And the third partition wall 132 is disposed on both sides with the partition wall 111 in between to prevent wastewater without ammonia from being degassed from overflowing the partition wall 111 and flowing into the organic matter oxidation tank 130. It can be blocked fundamentally.

In addition, the water treatment chamber 110 is formed as a tank type with its interior sealed to prevent the foul odor of the incoming wastewater from leaking to the outside, and is preferably made of a material with excellent corrosion resistance and wear resistance, such as SUS.

The chemical supply unit 140 is disposed at the front of the water treatment chamber 110 and supplies hypochlorous acid-based chemicals used to degass the ammonia contained in wastewater to the water treatment chamber 110.

Here, sodium hypochlorite (NaOCl) can be preferably used as the hypochlorous acid-based chemical, and in addition, slightly acidic HOCl (slightly acidic hypochlorous acid), sodium dichloroisocyanurate (DCCNa), and chlorine dioxide (ClO ₂ ), etc. can also be used. These hypochlorous acid-based chemicals can be supplied dissolved in water, and in some cases, may be supplied in powder form. Hereinafter, the use of sodium hypochlorite as the hypochlorous acid-based chemical will be described as an example.

In addition, as shown in FIGS. 1 and 2, the ammonia single-axis degassing tank 120 includes a degassing diffuser 151a that forms bubbles with air supplied from the blower 153 so that the supplied wastewater and chemicals are agitated with each other. 151b) is provided inside so that the ammonia component contained in the wastewater is removed through a degassing reaction with the sodium hypochlorite component of the medicine. That is, the ammonia component reacts with the hypochlorous acid-based component of the drug and is converted to chloramine component, which is then removed by degassing through strong aeration and stirring.
Here, as shown in FIG. 2, the sewage inlet 121 is formed to open laterally at the lower position of the ammonia single-axis degassing tank 120 and can supply sewage and wastewater toward the first degassing tank diffuser 151a.

In addition, the organic matter oxidation tank 130 is an oxidation tank diffuser that forms bubbles with air supplied from the blower 153 so that the wastewater flowing in from the ammonia single-axis degassing tank 120 is agitated while overflowing the partition wall 111. 152) is provided inside to remove organic matter and E. coli contained in the wastewater through an oxidation reaction with the sodium hypochlorite component remaining in the wastewater.

The blower 153 is connected to each diffuser 151 and 152 and can supply airflow generated while rotating to the degassing diffuser 151a and 151b and the oxidizing diffuser 152, and is connected to a signal control unit 700. The rotation timing or rotation speed can be driven and controlled according to the control signal. In addition, the drawing illustrates that the degassing diffuser 151a, 151b and the oxidizing diffuser 152 are connected together to one blower 153 to receive air at the same time, but this is not limited to this, and each air diffuser 151, 152 ) Each blower 153 is provided to be matched so that air can be supplied individually.

The wastewater rapidly mixed with hypochlorous acid-based chemicals in the ammonia single-axis degassing tank 120 undergoes a violent degassing reaction with bubbles generated by the degassing tank diffusers 151a and 151b, and is degassed into ammonia gas, and some of it is combined. It exists in the form of residual chlorine.

Here, the chemical reaction equation for degassing the ammonia is as follows.

Step 1: The available chlorine Cl ₂ contained in NaOCl reacts with water as shown in [Chemical Formula 1] below.

[Formula 1]

Cl₂ + H₂O → HOCl + HCl

HOCl → H+ + OCl-

Among these, HOCl reacts with ammonia as shown in [Chemical Formula 2] below.

[Formula 2]: Degassing reaction to form chloromere

NH₃ + HOCl → NH₂Cl↑ + H₂O

NH₂Cl + HOCl → NHCl₂↑ + H₂O

NHCl₂ + HOCl → NCl₃↑ + H₂O

Step 2: The available chlorine Cl ₂ contained in NaOCl reacts with ammonia as shown in [Chemical Formula 3] below.

[Formula 3]

3Cl ₂ +NH ₄ → N ₂ ↑+6HCl+2H ⁺

In addition, the wastewater further contains SBOD (Soluble Biochemical Oxygen Demand) and E. coli in addition to ammonia. The SBOD reacts with sodium hypochlorite and the dissolved BOD (Biochemical Oxygen Demand) is oxidized and decomposed to produce CO ₂ and H ₂ O. It is mineralized and decomposed in the form of E. coli, and its cell walls are destroyed by sodium hypochlorite and intracellular proteins are decomposed and eliminated through sterilization and disinfection.

The degassing tank diffuser (151a, 151b) and the oxidizing tank diffuser (152) function to provide bubbles for stirring the wastewater and hypochlorous acid-based chemicals to rapidly mix, and accelerate the degassing reaction of ammonia as necessary. It may also function to provide oxygen supply for oxygen.

A first exhaust port 124 is provided at the top of the ammonia single-axis degassing tank 120, so that the ammonia gas generated during degassing can be removed from the wastewater by being discharged to the outside through the first exhaust port 124.

In addition, in the organic matter oxidation tank 130, organic matter is oxidized in the process of agitating wastewater by sodium hypochlorite remaining after degassing ammonia (for example, 30 minutes). In the case of E. coli, cell walls are destroyed, and in the case of organic matter, oxidizing agent is used. Due to decomposition, the final products CO ₂ and H ₂ 0 are produced.

A second exhaust port 133 is provided at the top of the organic matter oxidation tank 130, so that by-product gases such as remaining ammonia gas and carbon dioxide can be removed from the wastewater by being discharged to the outside through the second exhaust port 133.

As described above, the supplied wastewater and hypochlorous acid-based chemicals are structured to be rapidly stirred, so that ammonia contained in the wastewater can be effectively removed within a short period of time (for example, 1 to 2 hours), thereby reducing the power used for water treatment. can be significantly reduced, and the amount of water treated per unit time can be increased, making it possible to miniaturize the ammonia single-axis degassing device (100).

In addition, the interior of the water treatment chamber 110 is divided into an ammonia single-axis degassing tank 120 and an organic matter oxidation tank 130, so that ammonia is intensively removed in the ammonia single-axis degassing tank 120, and ammonia is removed in the organic matter oxidation tank 130. By intensively removing organic substances in the wastewater, ammonia and organic substances contained in the wastewater can be effectively removed and wastewater treatment time can be significantly reduced.

Meanwhile, as shown in FIG. 2, the wastewater inlet 121 is disposed at the lower position of the ammonia single-axis degassing tank 120, and the inside of the ammonia single-axis degassing tank 120 includes a wastewater inlet 121 and a partition wall ( 111), a first partition 122 is provided between the wastewater inlet 121 and the wastewater inlet 121, and the first partition 122 is provided to guide the sewage water flowing into the lower part to rise. 122), it is disposed at the lower position and discharges air bubbles upward, so that the wastewater flowing into the lower part is guided by the first partition wall 122 and rises by air bubbles discharged from the first degassing diffuser 151a. Ammonia can be primarily removed through a degassing reaction in the form of chloramine during the first degassing time (e.g., 3 to 10 minutes, preferably around 5 minutes) while rapidly stirring with the hypochlorous acid-based chemical.

And, as shown in the figure, inside the ammonia single-axis degassing tank 120, the wastewater extends downward from the ceiling between the first partition wall 122 and the partition wall 111 and overflows the first partition wall 122. A second partition 123 is further provided to guide the downward movement, and a second degassing diffuser 151b is also disposed at the lower position between the first partition 122 and the second partition 123 to discharge air bubbles upward. can do.

Therefore, while the wastewater overflowing the first partition 122 is guided by the second partition 123 and descends, it is rapidly agitated with hypochlorous acid-based chemicals by bubbles discharged from the second degassing diffuser 151b. Ammonia may be removed secondarily through a degassing reaction in which the ammonia component is transformed into a chloramine component during the second degassing time (for example, 3 to 10 minutes, preferably around 5 minutes). In addition, a secondary degassing reaction can be performed on wastewater in which ammonia has been reduced through the primary degassing reaction, which can significantly reduce the ammonia removal time through the degassing reaction in the form of chloramine and significantly increase the water treatment amount per unit time. there is.

In addition, as shown in FIG. 3, the treated water discharge port 131 is mounted at the upper position of the organic material oxidation tank 130, and extends downward from the ceiling inside the organic material oxidation tank 130 to form a partition wall 111. ) is further provided with a third partition 132 that guides the wastewater overflowing downward and flowing into the lower part of the organic matter oxidation tank 130, and the oxidation tank diffuser 152 is connected to the third partition 132 and the treated water. It is disposed at a lower position between the discharge ports 131 to discharge air bubbles upward.

Accordingly, the wastewater flowing downward through the lower end of the third partition 132 is rapidly agitated with the remaining hypochlorous acid-based chemicals by the bubbles discharged while rising toward the treated water discharge port 131, and the set oxidation time ( For example, for 20 to 40 minutes, preferably around 30 minutes, it is possible to oxidize remaining organic matter, kill and deodorize E. coli, and improve the color of wastewater.
Additionally, as shown in FIG. 2 , the partition wall 111 may extend upward so that its upper end is positioned at a relatively higher position than the upper end of the first partition wall 122 . Through this partition wall 111, it is possible to minimize the flow of wastewater in which ammonia has not yet been degassed from the ammonia single-axis degassing tank 120 into the organic matter oxidation tank 130.

The control unit 700 drives and controls the blower 153 to control the amount of air bubbles discharged from the diffusers 151a, 15ab, and 152 provided in the ammonia single-axis degassing tank 120 and the organic matter oxidation tank 130, respectively, or the air bubble supply rate. The residence time of wastewater in each space can be adjusted by adjusting the bubble supply pressure or controlling the inflow of wastewater supplied from the multi-stage partition type flotation separation module 400. Accordingly, the wastewater and hypochlorous acid series in each space can be adjusted. You can control the time it takes for the chemical to degas.

As shown in FIG. 1, the chemical supply unit 140 is connected to a chemical storage tank 141 in which hypochlorous acid-based chemicals are stored, and is connected to the chemical storage tank 141 to receive the stored chemical and the ammonia single-axis degassing tank 120. Sewage water and hypochlorous acid are connected to the sewage water supply pipe 125, which supplies sewage water to the sewage inlet 121, through the chemical supply pipe 143, and are transported while discharging a set amount of hypochlorous acid-based chemicals into the inside of the sewage water supply pipe 125. It may include a chemical pump 142 that allows the chemical series to flow into the sewage inlet 121 in a mixed form.

Therefore, the time required for stirring wastewater and hypochlorous acid-based chemicals within the ammonia single-axis degassing tank 120 can be significantly reduced, and the efficiency of the ammonia degassing reaction within the ammonia single-axis degassing device 100 can be maximized.

Meanwhile, the ammonia single-axis degassing device 100 according to a preferred embodiment of the present invention uses the ammonia sensor 600 and the control unit 700 in real time according to the ammonia content contained in the wastewater flowing into the water treatment chamber 110. Ammonia can be efficiently removed by controlling the amount of hypochlorous acid-based chemicals.

For this purpose, the ammonia sensor 600 is disposed inside the organic matter oxidation tank 130, detects the ammonia component, and outputs an ammonia detection value. The control unit 700 is signal-connected to the chemical pump 142 and controls the drive to control the amount of hypochlorous acid-based chemical discharged from the chemical pump 142, and the ammonia detection value received from the ammonia sensor 600 is If it exceeds the set appropriate standard, the emission of hypochlorous acid-based chemicals increases, and if it falls below the set appropriate standard, the emission of hypochlorous acid-based chemicals is controlled to decrease.

Therefore, even if the ammonia content contained in the wastewater flowing into the water treatment chamber 110 changes, it can be automatically adjusted so that an appropriate amount of hypochlorous acid-based chemicals is injected in real time, so the amount of hypochlorous acid-based chemicals input is adjusted to the breakthrough point before the chlorine input step. By converting it into a chloramine component and degassing it, the amount of hypochlorous acid-based chemicals used can be significantly reduced.

Meanwhile, in addition to ammonia and organic matter, wastewater may contain suspended substances such as floc. In the ammonia single-axis degassing device 100 according to a preferred embodiment of the present invention, the suspended substances contained in wastewater are removed by floating them on the water surface. The separation module 400 is provided to pre-treat the wastewater to remove suspended solids before removing ammonia and organic matter, that is, before inputting the wastewater into the water treatment chamber 110.

For this purpose, as shown in FIG. 3, the multi-stage partition type floating separation module 400 is formed with a watertight internal space, a wastewater inlet 412 through which sewage water flows is formed on one side, and treated wastewater is discharged on the other side. A treated water outlet 413 is formed, and in the internal space, a plurality of lower partitions 414 extending upward from the floor and a plurality of upper partitions 415 extending downward from the ceiling are alternately arranged to form a plurality of bubble reaction tanks. It includes a reaction chamber 410 forming 416 and a bubble generator 420 (see FIG. 1) that generates micro- or nano-sized microbubbles and supplies them to the internal space.

Here, the multi-stage partition type floating separation module 400 restricts the temporary outflow of air bubbles step by step through a partition wall structure installed in multi-stage with respect to the flow direction of the lower part, maintaining the saturated bubble state and removing the floating particles. By removing it, not only can purification be done in a short time, but suspended solids contained in the treated water and discharged can be minimized.

As shown in Figure 3, the reaction chamber 410 of the multi-stage partition type flotation separation module 400 is a chamber that provides a reaction space for floating and removing suspended solids contained in the wastewater and fine bubbles while being supplied inside. As such, a predetermined internal space is formed where floating separation takes place, and wastewater is supplied to the internal space through the wastewater inlet 412, and purified wastewater is discharged to the outside through the treated water discharge port 413 disposed on the other side.

In addition, in the drawing, four bubble reaction tanks 416 are formed by a partition structure in which three lower partitions 414 and three upper partitions 415 are alternately arranged with respect to the flow direction of the wastewater within the reaction chamber 410. Although this is an example, it is not limited to this, and it is of course possible to form three or more bubble reaction tanks or more than five bubble reaction tanks in consideration of purification efficiency according to the concentration of suspended solids contained in wastewater and the amount of fine bubbles supplied.

In addition, the wastewater flowing in through the wastewater inlet 412 may contain suspended solids of a size that do not float due to fine bubbles. Typically, suspended solids of this size settle to the bottom in the form of sludge over time. may not be discharged to the outside. For this purpose, an outlet 418 is formed at the bottom of each bubble reaction tank 416 to discharge the settled sediment. Here, in order to smoothly remove sludge, slopes sloping downward at a predetermined angle (for example, 45 degrees) are formed on both sides of the outlet 418 to enable rapid discharge of sludge through the outlet 418. .

The multi-stage partition type flotation separation module 400 is disposed on the upper part of the reaction chamber 410 and rotates a rotating chain 432 equipped with a plurality of skimmers 431 on the outer surface of the sewage and wastewater by the fine bubbles. It is provided with a flotation sludge discharge unit 430 that scrapes off the flotation sludge floating on the surface of the water and discharges it to a treated water discharge port 413 disposed at the top of the reaction chamber 410. Here, the rotating chain 432 is connected in the form of an endless track between the rotating rolls 433 spaced apart on both sides of the reaction chamber 410, and the rotating roll 433 receives a control signal from the control unit 700. A drive motor (not shown) that rotates along the axis is connected, and the skimmer 431 can be rotated circularly using the rotational force of the drive motor.

As shown in the figure, a microbubble inlet 421 is formed on one side of the reaction chamber 410 for injecting microbubbles generated by the bubble generator 420 into the internal space, and on the other side, each bubble reaction tank 416 is formed. ) A treated water supply port 424 is formed to discharge a portion of the treated water that passes through the treated water and moves toward the treated water discharge port 413, and the bubble generator 420 has a treated water supply port 424 and a fine bubble inlet ( 421), which is disposed on a transfer line connected between the two to generate microbubbles in the supplied treated water and discharge the generated microbubbles into the microbubble inlet 421.

This multi-stage partition-type flotation separation module (400) can effectively remove suspended solids particles contained in sewage and wastewater, and through this, wastewater with suspended solids removed can be supplied to the ammonia single-stage degassing tank (120) to remove ammonia. The purification efficiency using toothpaste can be maximized in the base tank 120 and the organic material oxidation tank 130.

In addition, as shown in FIG. 1, the ammonia single-axis degassing tank 120 is disposed at the rear end of the multi-stage partition type floating separation module 400 and is connected to the sewage inlet of the ammonia single-axis degassing tank 120 through the wastewater supply pipe 125. (121) is connected to the treated water outlet 413 of the reaction chamber 410 and the treated wastewater is supplied by the multi-diaphragm floating separation module 400, thereby effectively removing the ammonia component of the wastewater pretreated with hypochlorous acid-based chemicals. It can be purified within a short period of time and suspended solids contained in the treated water and discharged can be minimized.

Meanwhile, the ammonia single-axis degassing device 100 according to a preferred embodiment of the present invention is further equipped with a high-speed flocculation module 200 and a non-powered floc flocculation module 300 in addition to the multi-stage partition type floating separation module 400 described above. The suspended solids separated in the flotation separation module 400 can be coagulated more efficiently in advance.

The high-speed flocculation module 200 replaces the function of the conventional rapid agitation tank by swirling the inflow wastewater and coagulant inside to completely dissolve the coagulant, thereby maximizing the coagulation efficiency between the dissolved coagulant and suspended solids in the wastewater within a short period of time. It is a purification device for

As shown in FIG. 1, the high-speed flocculation module 200 has a wastewater inlet connected to the flow rate adjustment tank 10 in which wastewater to be purified is stored, and a wastewater discharge port connected to the wastewater inlet side of the non-powered flocculation module 300. is equipped with a stirring blade for stirring the supplied wastewater and coagulant.

As shown in Figures 1 and 4, the non-powered floc flocculation module 300 consists of a plurality of flocculation tanks 321 divided into upper and lower sections inside the flocculation chamber 310 to replace the function of the conventional mechanical slow stirring tank. It is partitioned and the wastewater from each flocculation tank 321 flows into the interior of the adjacent flocculation tank 321 arranged at the bottom due to a drop, thereby creating a circulating water flow, thereby removing the fine particles contained in the wastewater without any separate stirring power. Suspended substances are circulated internally by water currents and come into contact with each other to condense to a certain size.

For this purpose, as shown in the drawing, a watertight internal space is formed, a sewage water inlet 311 connected to the wastewater discharge port of the high-speed coagulation module 200 is formed at the upper part, and a flocculation chamber 310 is formed with a wastewater discharge port 312 at the lower part. and a partition wall 320 disposed laterally inside the coagulation chamber 310, dividing the internal space into a plurality of coagulation tanks 321 divided into upper and lower sections, and having communication holes 322 opening upward and downward in the central portion. And, it includes a turbulence prevention plate 330 horizontally disposed at a lower position of each communication hole 322.

Here, the flocculation chamber 310 is formed as a sealed tank type to prevent the odor of the inflow sewage water from leaking to the outside, and is made of a material with excellent corrosion resistance and wear resistance, such as suture.

In addition, the drawing illustrates that three flocculation tanks 321 are formed inside the chamber by two partition walls 320, but one or three or more partition walls 320 are arranged to form two or four or more flocculation tanks 321. may form. Sewage water flowing into the wastewater inlet 311 disposed at the top of the flocculation chamber 310 flows into the first flocculation tank 321 partitioned by the first partition 320, and the inflow wastewater flows into the second flocculation tank 321 through the communication hole 322. It is discharged to the flocculation tank 321, and the wastewater flowing into the second flocculation tank 321 is discharged to the third flocculation tank 321 through the communication hole 322 and finally the sewage wastewater discharge formed at the bottom of the flocculation chamber 310 ( 312) and is discharged to the outside.

In this way, as it is designed as a multi-stage coagulation structure in which wastewater flows in and discharges from the upper part, the wastewater flowing into the upper part of each coagulation tank through the wastewater inlet 311 or the communication hole 322 is directed downward by a drop at the central position. A falling wastewater flow is formed, and the wastewater that falls and comes in contact with the bottom surface of each flocculation tank 321 moves along the bottom surface and touches the inner wall of the flocculation tank 321 as it moves, creating a rising water flow that rises along the wall. By forming, a circulating water flow is created on both sides of the center of each flocculation tank 321.

Accordingly, the suspended solids contained in the wastewater introduced from the outside can be coagulated to form a lump larger than the size at the time of introduction by circulating together and contacting each other by the circulating water flow generated in the first coagulation tank 321, and the flocculated The suspended solids become larger in size as they pass through the second flocculation tank 321 and the third flocculation tank 321.

Here, as shown in the drawing, an inclined portion 331 is formed around the end of the turbulence prevention plate 330 in a shape that gradually increases toward the outside, so that the inflowing wastewater is prevented from stagnating on the turbulence prevention plate 330. The time can be increased, and the drop width can be increased to further increase the cohesion efficiency.

In addition, an inclined surface 323 is formed around the end of the partition wall 320 in a shape that gradually slopes upward toward the outside, or the partition wall 320 is formed in a shape that gradually slopes upward from the center to the outside. The sludge can be guided to move toward the communication hole 322 without stagnating on the upper surface of the partition wall 320.

In addition, a pressure regulator pipe 340 is disposed at the top of the coagulation chamber 310 to discharge air in the internal space to the outside, and the control unit 700 controls the coagulation chamber according to the pressure detection signal from the pressure sensor 341. When the internal pressure of 310 exceeds the set value, the pressure regulating pipe 340 is driven and controlled to maintain the set value.

In addition, the sewage water discharge port 312 and the sewage inlet 4121 of the multi-stage partition type floating separation module 400 are connected to the sewage water discharge pipe 360, and the sewage water discharge pipe 360 is connected to the sewage water discharge pipe 360. A curved bent portion is formed at a position opposite to the discharge direction of the wastewater, thereby minimizing the separation of the agglomerated substances contained in the wastewater by hitting the inner wall of the wastewater discharge pipe 360 while being discharged through the wastewater discharge port 312. can do.

Using the high-speed flocculation module (200) and the non-powered flux flocculation module (300), suspended solids can be coagulated within a short time to the extent that they can be floated by fine bubbles through the multi-stage partition-type flotation separation module (400). By increasing the flotation efficiency, the purified treated water can be discharged to the outside to minimize suspended solids.

Next, a water treatment method for removing ammonia and organic substances contained in wastewater using the ammonia single-axis degassing device 100 according to the preferred embodiment of the present invention described above will be described.

As shown in Figure 5, the water treatment method according to a preferred embodiment of the present invention includes an ammonia degassing step (S130) and an organic matter oxidation step (S140).

First, the ammonia single-axis degassing step (S130) is a step for removing ammonia contained in the wastewater supplied into the water treatment chamber 110. Hypochlorous acid-based chemicals are supplied, and the blower 153 is controlled to form bubbles in the degassing tank diffusers 151a and 151b while wastewater at a certain level flows into the ammonia single-axle degassing tank 120, so that the wastewater and the chemicals interact with each other. As it is stirred, the ammonia component contained in the wastewater is removed through a degassing reaction with the hypochlorous acid component of the drug in the form of chloromere.

The organic matter oxidation step (S140) is a step for removing organic substances contained in wastewater from which ammonia has been removed through the ammonia single-axis degassing step (S130). When the wastewater flows into the organic matter oxidation tank 130 at a certain level, the blower 153 is controlled to form bubbles in the oxidation tank diffuser 152. As the inflow wastewater is stirred, organic matter and E. coli contained in the wastewater are removed from the wastewater. It is removed through an oxidation reaction with the remaining hypochlorous acid-based components.

Through this ammonia short-term degassing step (S130) and organic matter oxidation step (S140), sewage water and hypochlorous acid-based chemicals can be rapidly stirred, thereby effectively removing ammonia contained in sewage water in a short period of time, and thus the power used for water treatment. can be significantly reduced, and the amount of water treated per unit time can be increased, making it possible to miniaturize the ammonia single-axis degassing device (100).

In addition, it is divided into an ammonia single-axis degassing step (S130) and an organic matter oxidation step (S140). In the ammonia single-axis degassing step (S130), ammonia is intensively removed, and in the organic matter oxidation step (S140), the organic matter of the wastewater from which ammonia has been removed is intensively removed. This effectively removes ammonia and organic substances contained in wastewater and significantly reduces wastewater treatment time.

In addition, the ammonia single-axis degassing step (S130) is performed by a control unit ( By controlling the blower 153 with 700, the wastewater flowing into the lower part is guided by the first partition 122 and is rapidly stirred with hypochlorous acid-based chemicals by bubbles discharged while rising, thereby causing a degassing reaction in the form of chloramine. It may include a primary ammonia short-axis degassing step (S131) in which ammonia is primarily removed through the process.

Therefore, while the sewage water flowing into the lower part is guided by the first partition 122 and rises, it is rapidly agitated with hypochlorous acid-based chemicals by bubbles discharged from the first degassing diffuser 151a, and is converted into chloramine form. Ammonia can be primarily removed through a degassing reaction.

In addition, the ammonia single-axis degassing step (S130) is performed by a control unit ( By controlling the blower 153 with 700, the wastewater overflowing the first partition 122 is guided by the second partition 123 and is rapidly agitated with hypochlorous acid-based chemicals by bubbles discharged while descending, thereby releasing chloramine. A secondary ammonia degassing step (S132) may be further included in which ammonia is removed secondarily through a degassing reaction.

Accordingly, the wastewater overflowing the first partition 122 is guided by the second partition 123 and is rapidly agitated with hypochlorous acid-based chemicals by bubbles discharged from the second degassing diffuser 151b while descending. As a result, ammonia can be removed secondarily through a degassing reaction in which the ammonia component is transformed into a chloramine component. In addition, a secondary degassing reaction can be performed on wastewater in which ammonia has been reduced through the primary degassing reaction, which can significantly reduce the ammonia removal time through the degassing reaction in the form of chloramine and significantly increase the water treatment amount per unit time. there is.

In addition, in the organic matter oxidation step (S140), the oxidation oxygen diffuser 152 disposed at the lower position between the third partition 132 and the treated water discharge port 131 operates a blower with the control unit 700 to discharge air bubbles upward. (153) is controlled so that the wastewater flowing into the lower part through the lower end of the third partition 132 is stirred and oxidized with hypochlorous acid-based chemicals by bubbles discharged while rising toward the treated water discharge port 131. You can.

Therefore, while the sewage water flowing into the lower part is guided by the third partition 132 and rises, it is rapidly stirred with the remaining hypochlorous acid-based chemicals by bubbles discharged from the oxidation orogen diffuser 152, thereby oxidizing and oxidizing the remaining organic matter. It can kill and deodorize E. coli and improve the color of wastewater.

And, referring to Figures 1 and 5, the water treatment method according to a preferred embodiment of the present invention includes a rapid mixing step of sewage and chemicals so that hypochlorous acid-based chemicals are supplied in a mixed form to the wastewater supplied to the water treatment chamber 110. (S120) may be further included.

In the step of rapid mixing of sewage and chemicals (S120), the chemical pump 142 is controlled by the control unit 700 so that the amount of hypochlorous acid-based chemicals set by the chemical pump 142 is discharged into the sewage and wastewater supply pipe 125. By allowing the transported wastewater and hypochlorous acid-based chemicals to flow into the sewage inlet 121 in a mixed form, the time required to stir the wastewater and hypochlorous acid-based chemicals within the ammonia single-stage degassing tank 120 can be significantly reduced, and ammonia can be reduced significantly. The efficiency of the ammonia degassing reaction within the single-axis degassing device 100 can be maximized.

In addition, the ammonia single-axis degassing device 100 further includes an ammonia sensor 600 that is disposed inside the organic matter oxidation tank 130 and detects an ammonia component and outputs an ammonia detection value, and the control unit 700 is signal connected to the chemical pump 142 and can be driven to control the discharge amount of hypochlorous acid-based chemicals discharged from the chemical pump 142.

In addition, in the step of rapid mixing of sewage and chemicals (S120), when the ammonia detection value received from the ammonia sensor 600 using the control unit 700 exceeds the set appropriate standard value, the discharge of hypochlorous acid-based chemicals increases and the set appropriate standard value is performed. If it is less than that, the emission of hypochlorous acid-based chemicals can be reduced.

Accordingly, even if the ammonia content contained in the wastewater flowing into the water treatment chamber 110 changes, it can be automatically adjusted so that an appropriate amount of hypochlorous acid-based chemicals is injected in real time, so the amount of hypochlorous acid-based chemicals input is adjusted before the breakthrough point chlorine injection step. By converting it into a chloramine component and degassing it, the amount of hypochlorous acid-based chemicals used can be significantly reduced.

And, as shown in Figures 1 and 5, the water treatment method according to a preferred embodiment of the present invention mixes wastewater and chemicals before the rapid mixing step of sewage and chemicals (S120) and supplies them to the water treatment chamber 110. A sewage pretreatment step (S110) may be further performed.

In the sewage pretreatment step (S110), sewage water is supplied to the wastewater inlet 412 of the multi-stage partition floating separation module 400, and the bubble generator 420 generates bubbles while the wastewater at a certain level flows into the reaction chamber 410. This causes suspended solids contained in wastewater to float on the surface of the water.

In addition, in the step of rapid mixing of wastewater and chemicals (S120), pretreated wastewater with suspended solids removed by the multi-stage partition-type floating separation module (400) is supplied to the sewage inlet (121) of the ammonia single-axis degassing tank (120). As a result, the ammonia component of wastewater pretreated with hypochlorous acid-based chemicals can be effectively removed, purification can be done in a short period of time, and suspended solids contained in the treated water and discharged can be minimized.

As described above, although the present invention has been described with limited examples and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following will be understood by those skilled in the art to which the present invention pertains.
