Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wastewater treatment apparatus,

The present invention relates to a wastewater treatment apparatus and a treatment method thereof, and more particularly, to a wastewater treatment apparatus and a treatment method thereof, more particularly, to a wastewater treatment apparatus and method for treating wastewater by treating wastewater with an ionizing gas and air, The present invention relates to an apparatus for treating wastewater and a method for treating wastewater, which is capable of increasing the purification efficiency of wastewater by separating the purified gas-liquid mixture into treated water and foam sludge.

Due to rapid industrial development, population growth and population concentration in the city, the proportion of inorganic and organic components in wastewater is increasing with the increase of various water contents. Such wastewater contains high concentrations of organic matter such as COD (Chemical Oxygen Demand), BOD (Biochemical Oxygen Demand), SS (suspended solid), nitrogen and phosphorus and flows into rivers, lakes and rivers, And destruction of the ecosystem due to toxicity. Therefore, wastewater should be purified and discharged to a level lower than the reference value by setting certain criteria.

On the other hand, water treatment technology using membrane as a water pollution control technology has been widely used to enhance the removal efficiency of toxic pollutants and advanced treatment technology to remove them and conventional treatment facilities. Particularly, the water treatment technique using such a membrane is applied to a water treatment system by a combination of the following: 1) a chemical, a biological treatment and a membrane combined use, 2) a combination of a chemical treatment and a membrane, and 3) have.

However, in the field of water treatment technology using membranes, membrane processes have been increasingly used for water treatment, refractory industrial wastewater treatment, livestock wastewater treatment, secondary treatment of landfill leachate and contaminated groundwater treatment, ) Is easily generated and is pointed out as a great disadvantage to its usability.

Also, if the permeation rate (permeability), which is a performance index of the membrane, is lowered, the membrane is reused through various cleaning processes. However, the membrane performance can not be recovered by 100% by the conventional cleaning method utilizing cleaning chemicals, compressed air and washing water In addition, secondary contamination occurs due to the chemicals used in the cleaning process.

Such a conventional cleaning method adopts most of the backwashing method in which the flow of the membrane is temporarily disconnected, thereby periodically stopping the flow of the process. That is, in the water treatment technique using the conventional membrane, it is difficult to smoothly and stably obtain the treated water amount for a long period of use because foreign matter of the wastewater adheres to the separator to block the micropores in the process of wastewater.

In addition, when the conventional water treatment technique for removing nitrogen and phosphorus by biological treatment is applied, there is a problem that the carbon content ratio (C / N) to the nitrogen content of the introduced wastewater is low, To increase it, carbon sources should be supplied during the water treatment process.

However, it is difficult to artificially supply the carbon source during the water treatment process because it requires considerable cost in terms of maintenance cost and requires a separate apparatus. Since such a conventional wastewater treatment technology uses a structure manufactured on the ground by civil engineering using concrete, the installation cost and the period are considerably consumed and the installation space is occupied so that there are restrictions on practical use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus and method for treating wastewater according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view showing an apparatus for treating wastewater according to an embodiment of the present invention.

1, an apparatus for treating wastewater according to an embodiment of the present invention includes a water collecting tank 110, an ionizing gas generating apparatus 120, a water pressure pump 130, an electrolytic cylinder 140, a reaction tube 160 ), A nodule injection pipe (170), and a settling tank (180).

The water collecting tank 110 is a water tank for collecting wastewater for processing and separates the foam sludge from the wastewater flowing through the first water feed pipe 111 through the first baffle 113 and the second partition wall 114 And collects it. The first partition 113 is formed vertically downward on one side of the upper end of the water collecting vessel 110 and the second partition 114 is formed at a lower end of the water collecting vessel 110 And a part of the first barrier rib 113 is formed to overlap with the first barrier rib 113 vertically upward. A filter 115 is disposed at the lower end of the water collecting tank 110 to filter particulate matter from the wastewater passing through the partition walls 113 and 114. Here, whether or not the wastewater is introduced is determined by the first on-off valve 112, and whether the wastewater is discharged or not is determined by the second on-off valve 117. The wastewater passing through the water collecting tank 110 is transferred through the second water supply pipe 116. At this time, the second water supply pipe 116 is connected to the mixed water collecting tank 123.

The ionizing gas generator 120 ionizes the air introduced from the outside by using electrons generated through the high voltage discharge to generate ionized gas. The ionized gas generated by the ionizing gas generator 120 includes ions such as OH ^- and O ^{2 -} and oxidizing gas components such as ozone (O ₃ ) and hydrogen dioxide (HO ₂ ). The ionized gas flowing out of the ionized gas generator 120 is moved through the gas pipe 121 and the supply of the ionized gas is controlled by the first gas valve 121a. The ionizing gas (especially, ozone) used in wastewater treatment has a strong oxidizing power of 7 times that of chlorine in the natural world, and it has a powerful sterilizing power (ozone kills bacteria, moss, virus, not less than 99.99% in 10 seconds, , The virus is not sterilizable in the case of chlorine, and the carcinogenic substance such as THN is generated. In addition to this, it is combined with the odor molecule in the water to remove the odor, and the turbidity in the water is greatly lowered It also has a vesicant effect. It decomposes toxic substances such as harmful organic substances coming from factories, industrial wastewater and laundry detergents, and cyanide and phenol, and makes it easy to remove heavy metals such as mercury and iron manganese, Not only does it have processing advantages that do not appear during treatment, but it eventually leads back to oxygen to significantly improve BOD, COD, and 2 It has the advantage of not making any car pollutants (THM in the case of chlorine) at all. A known ozone generator is used for the ozone treatment in the wastewater treatment. Examples of the artificial ozone generating method include a silent discharge method, an electrolytic method, a photochemical method, and the like. Generally, The law is widely used. The silent discharge method applies a high voltage (6,000 ~ 18,000V) of alternating current and puts a dielectric such as glass and ceramics between the opposite electrodes and injects air or oxygen into the discharge space to generate ozone. The ozonizer and its driving principle are well known to those skilled in the art and will not be described in further detail.

The gas tank 122 prevents the backflow of moisture or a gas-liquid mixture, and relays the ionized gas generated by the ionizing-gas generating apparatus 120 to be supplied to the mixing and collecting tank 123. The ionized gas passing through the gas tank 122 is moved to the designated path through the second gas pipe 124 and the relaying of the ionized gas is controlled by the second gas valve 124a. At this time, when the gas-liquid mixture is present in the mixed water collecting tank 123, it may happen that the moisture or the gas-liquid mixture flows backward through the second gas pipe 124. Therefore, the gas tank 122 is provided for preventing such backflow phenomenon, and the moisture or gas-liquid mixture loaded in the gas tank 122 can be discharged through the discharge valve 122a.

The mixed water collecting tank 123 receives the treated water to be purified through the second water feed pipe 116. At this time, whether the treated water is supplied or not is influenced by the second on-off valve 117.

The mixed water collecting tank 123 serves to mix the ionized gas and the treated water flowing through the second gas pipe 124 and the second water feed pipe 116. That is, the mixed water collecting tank 123 mixes the ionized gas and the treated water to induce the ionized gas to treat the treated water first. A suction pump 130 is connected to the mixed water collecting tank 123. The suction force of the suction pump 130 facilitates gas-liquid mixing of the ionized gas and the treated water. Further, the suction pump 130 moves the gas-liquid mixture to the electrolytic cylinder 140 through the third water feed pipe 131.

The electrolytic cylinder 140 is connected to the suction pump 130 via the third water supply pipe 131 and performs electrolytic reaction of the gas-liquid mixture mixed by the suction pump 130 to perform oxidative decomposition, reduction decomposition . That is, the gas-liquid mixture flowing into the electrolytic cylinder 140 is brought into contact with the anode of the electrolytic cylinder 140, and the gas-liquid mixture is oxidatively decomposed or reduced and decomposed, whereby the harmful components are removed (separated). The inner electrode wall 141 of the electrolytic cylinder 140 is connected to the negative terminal of the battery 145 and the electrode rotation bar 142 is connected to the positive terminal of the battery 145. The battery 145 supplies the rectified DC voltage and current to the electrolytic cylinder 140. At this time, it is preferable that the battery 145 is implemented such that the voltage and the current are automatically adjusted and supplied to the concentration of the wastewater to be treated (i.e., pH, conductivity, COD concentration, basicity, etc.). For example, it is preferable that the battery 145 is implemented such that the higher the concentration of the wastewater to be treated, the lower the voltage and the current, and the lower the concentration of the wastewater to be treated, the higher the voltage and the current. Although the internal electrode wall 141 of the electrolytic cylinder 140 is connected to the negative terminal of the battery 145 and the electrode rotation bar 142 is connected to the positive terminal of the battery 145, 145 may be reversed. The gas-liquid mixture oxidatively decomposed or reduced by the electrolytic cylinder 140 is transferred to the irradiation passage pipe 146 through the water supply pipe 145. The internal construction and operation principle of the electrolytic cylinder 140 are as follows.

2 is a view showing a configuration of an electrolytic cylinder according to an embodiment of the present invention.

2, the electrolytic cylinder 140 includes a housing 10 having a cylindrical shape with both open sides, and the lower end or one side of the housing 10 is closed by a cap 12. [ The cap 12 is provided with a suction port 14 so as to allow wastewater to be introduced thereinto. The wastewater which has been electrolytically reacted with the inside of the housing 10 at a position on the upper side or the other side of the housing 10 The discharge port 16, which can be discharged, is also replaceably fixed. Inside the housing 10, there is provided an internal electrode wall 20 insulated and bonded to the inner wall of the housing 10 and to which a power source is applied. The housing 10 is provided with an electrode rotation bar 30 which is rotated about the central axis of the housing 10 by applying a power source from one end of the housing 10 along the central axis thereof. At this time, at least one bearing 26 may be provided between the inner electrode wall 20 and the electrode rotation bar 30, so that the interval between the inner electrode wall 20 and the electrode rotation bar 30 is constant maintain. Here, it is preferable that the inner electrode wall 20 is made of titanium to electrolyze the wastewater. At this time, a power terminal 22 is connected to the internal electrode wall 20 so as to receive power of, for example, an anode (+). The power terminal 22 is connected to the inner electrode wall 20 and the inner electrode wall 20 in a stable manner inside the housing 10 and the second tab 18b, And is connected to the inner electrode wall 20 by a connecting piece 24 so as to be fixed and held. The connecting piece 24 is connected to the inner electrode wall 20 through the housing 10 and the second tab 18b and is connected to the end 24a of the connecting piece 24. The power terminal 22 is easily It is preferable that the nut 24b is releasably provided. The bearing 26 provided between the inner electrode wall 20 and the electrode rotation bar 30 allows the electrode rotation bar 30 to rotate stably while maintaining a predetermined gap with the inner electrode wall 20, At the same time, it is preferable that the inner electrode wall 20 and the electrode rotation bar 30 are formed in a discontinuous ring shape or a mesh-like material so that a fluid such as wastewater can easily flow.

A first tab 18a is inserted into the lower end or one side of the housing 10 and a second tab 18b is inserted into the upper or the other end. The second tab 18b is provided with the discharge port 16 described above and the spiral 19 can be formed so that the packing 34 can be coupled in a threaded manner.

An electrode rotation bar (30) is provided on the inner side of the inner electrode wall (20) while maintaining a predetermined gap therebetween. The center axis of the electrode rotation bar 30 is preferably aligned with the central axis of the housing 10, and the material is preferably platinum. At this time, a power terminal 32 may be connected to the end portion 30a of the electrode rotation bar 30, for example, to apply a negative (-) power source to the internal electrode tube 30. [ In this case, the power supply terminal 32 is idled into the end portion 30a of the electrode rotation bar 30 so that the electrode rotation bar 30 can freely rotate, and is fixed or limited by the nut 30b . Particularly, in the electrode rotating bar 30, the electrode rotating bar 30 can be stably and accurately fixed and held in the housing 10 and the liquid tightness can be maintained. In addition, the packing 34 is provided so as to rotate the electrode rotating bar 30 It is preferable to extrapolate. At this time, it is preferable that the packing 34 is formed of a carbon packing, and it is preferable that a fixing ring 36 made of rubber is interposed in order to firmly and integrally fix the electrode 34 with the electrode rotation bar 30. A spiral 37 is screwed to the spiral 19 formed on the second tab 18b so as to be rotatably coupled to the second tab 18b of the housing 10 around the packing 34 . Alternatively, the packing 34 may be provided with a plurality of insertion grooves 38 for inserting a rotary tool so as to rotate the packing 34.

On the other hand, a guide groove 40 may be formed on one side of the electrode rotation bar 30 as shown in FIG. At this time, the depth of the guide groove 40 is formed deeper from the upper side to the lower side, and the moving member 50 can be installed in the guide groove 40 so as to be movable up and down along the direction of the guide groove 40 . A brush 60 is provided on the opposite surface of the movable member 50 to a length equal to or longer than the interval between the internal electrode wall 20 and the electrode rotation bar 30. In this case, it is preferable that the length of the brush 60 is set to be longer than the distance between the internal electrode wall 20 and the electrode rotation bar 30 when the shifting member 50 is located at the lowest position. The movable member 50 is moved upward by the centrifugal force of the electrode rotation bar 30 so that the foreign substance adhered to the internal electrode wall 20 is transferred to the brush 60 So that foreign matter can be prevented from being deposited on the internal electrode wall 20. [

Referring again to FIG. 1, the irradiation passage pipe 146 serves to move the gas-liquid mixture introduced through the water supply pipe 55 through a predetermined path. The irradiation passage pipe 146 is preferably made of a ceramic dielectric tube (transparent body) or a glass tube so that electromagnetic waves and energy can efficiently penetrate (be irradiated). Also, it is preferable that the irradiation passage pipe 146 is formed in a spiral planar shape or a cochlea (vortex) shape so that the gas / liquid mixture can be irradiated with electromagnetic waves and energy for a longest time within the irradiation tube 147 region.

The electron irradiating device 150 generates a resonant cavity oscillation output of a magnetic pole including electromagnetic waves and energy, and concentrates the generated electromagnetic wave and energy at a predetermined position of the irradiation path tube 146. As shown in FIG. 4, the electron irradiating device 150 includes a high voltage generating unit 151 configured to include a high voltage transformer, a second high voltage coil, and a second low voltage coil to step up the input voltage to a high voltage, a high voltage generating unit A charging / discharging capacitor 152 for charging and discharging a high voltage generated in the capacitor 151, a diode 153 having a rectifying characteristic for allowing the current to flow only in one direction and not flowing in the opposite direction, an ultra-high a magnetron 154 that oscillates the frequency UHF, an irradiating antenna 155 that emits electromagnetic waves and energy generated by the electron irradiating device 150, and an electromagnetic wave and energy And an irradiating tube 156 for irradiating the specimen to a specific position. Here, the electron tube 154 generally has an anode of pure copper and an anode and a grid in the axial direction. When a magnetic field is applied in the axial direction of the cathode, the electrons protruding in the radial direction from the cathode are attracted to the anode and at the same time, they are subjected to a force perpendicular to the traveling direction by the magnetic field. As a result, electrons move in a helical motion. When the intensity of the magnetic field is increased, the amount of electron bending increases and the electron is rotated several times before reaching the anode. When the strength of the magnetic field reaches a certain limit (critical magnetic flux density), the electrons hardly reach the anode. At this time, a rotating electric pole (electron electrode) is generated around the cathode, And vibration continues to be stimulated. The oscillation frequency is mostly determined by the oscillation circuit and is highly efficient, and also the large output is obtained. The oscillation output generated in the electron tube 154 includes electromagnetic waves of several hertz (for example, 1.5 to 3 GHz) and several KW energy (i.e., impact energy).

The reflector 157 reflects the electromagnetic wave and the electron energy transmitted through the irradiation path tube 146 at the lower end of the irradiation path tube 146 and transmits the electromagnetic wave and energy to the gas-liquid mixture in the irradiation path tube 146 Investigate. The reflecting mirror 157 has an effect of maximizing the reaction efficiency by irradiating electromagnetic waves and energy transmitted through the irradiation path tube 146. For this purpose, the reflector 157 is made of a stainless steel or titanium alloy material having a good reflectance, So that electromagnetic waves and energies are concentrated on the electromagnetic waves.

The reaction tube 160 is connected to the irradiation passage pipe 146. The reaction tube 160 is formed by forcibly contacting the electrolytically reacted ions, hydroxyl groups, and bubbled electrolytic gases with the wastewater to oxidize, Thereby activating the aggregation reaction. At this time, the reaction tube 160 is formed to maintain a certain width (for example, an electrolytic cylinder: reaction tube = 3: 5) with the electrolytic cylinder 140, , 3m) is preferably maintained.

The nodal injection pipe 170 is connected to the reaction pipe 160 through a fourth water supply pipe 165 and is composed of a plurality of nodal injection ports 171. The gas-liquid mixture, which has passed through the reaction pipe 160, And performs spraying. The gas-liquid mixture flowing through the reaction pipe 160 and the fourth water pipe 165 is compressed and mixed while passing through the nozzle injection holes 171 of the nozzle injection pipe 170. The principle that the gas-liquid mixture passing through the nodal injection orifices 171 is compressed and mixed is based on the Bernoulli theorem, which is the hydrodynamic theorem which shows the relationship between the pressure in the moving fluid and the flow velocity, and the height to an arbitrary horizontal plane. Bernoulli's theorem is that the sum of the kinetic energy of a moving fluid, the energy by the pressure of the fluid, the potential energy by gravity on an arbitrary horizontal plane, and the kinetic energy of the fluid are constant. The Bernoulli theorem, therefore, is the principle of energy conservation for ideal fluids with uniform or laminar flow. Thus, according to Bernoulli theorem, a decrease in fluid pressure means an increase in flow rate. For example, when fluid flows through a conduit whose cross-sectional area lies on a horizontal plane, the flow rate increases as the cross-sectional area of the conduit decreases. Therefore, the pressure at which the fluid acts on the conduit becomes the smallest at the portion where the cross-sectional area of the conduit is minimum. In order to apply the Bernoulli theorem to the present invention, annular nozzle openings 161 are formed in a certain region of the nozzle injection tube 170 at a predetermined length, and by limiting the vapor-liquid mixture passing through these nozzle openings 171, Inducing the mixture to vortex and compress and mix. Since the plurality of nodal injection ports 171 are formed in the nodal injection pipe 170, the gas-liquid mixture is compressed and mixed a plurality of times each time it passes through the nodal injection ports 171. Therefore, as the process is repeated, the ionization gas of the gas-liquid mixture is completely decomposed and a part of oxygen is oxidized and a part is dissolved, thereby maximizing the purification treatment. The discharge of the vapor-liquid mixture that has passed through the nodal injection pipe 170 is determined by the fourth opening / closing valve 172.

The sedimentation tank 180 collects the gas-liquid mixture that has passed through the nodal injection pipe 170 and separates the gas-liquid mixture discharged from the nodal injection pipe 170 into the treated water and the foamed sludge. The treated water in the gas-liquid mixture flowing into the settling tank 180 is discharged to the outside through the third partition 181 and the fourth partition 182. The third partition 181 is formed on one side of the upper end of the settling tank 180 and the fourth partition 182 is formed at a predetermined distance from the third partition 181, Some overlapping is formed. In addition, a moving hole 183 for directly discharging treated water at the lower end is formed in the fourth partition wall 182. The treated water having passed through the third partition 181 and the fourth partition 182 is discharged through the first discharge pipe 184 and the discharge of treated water is determined by the fifth open / close valve 185.

In addition, a foam outlet 187 for discharging the foamed sludge floated is formed on one side of the top of the settling tank 180. A separating and collecting tank 190 for collecting the foamed sludge discharged from the foam outlet 187 of the sedimentation tank 180 is formed to be coupled to the sedimentation tank 180 in the lower end direction of the foam outlet 187. The first conveying pipe 186 and the second conveying pipe 191 are connected to one side of the lower end of the settling tank 180 and the separating and collecting tank 190 and the first conveying pipe 186 And the sludge discharged to the second conveying pipe 191 are conveyed to the collecting tank 110 through the third conveying pipe 193. The returned sludge is mixed with wastewater flowing into the water collecting tank (110) and used as an oxidation catalyst. When the wastewater treatment process is completed, the gas-liquid mixture remaining in the electrolytic cylinder 140 and the reaction tube 160 is discharged through the discharge pipe 143 connected to the inlet of the electrolytic cylinder 140. Whether or not the residual gas-liquid mixture is discharged is determined by the seventh open / close valve 144. As described above, the ionizing gas generating apparatus 120 and the nodule distributing pipe 170 are implemented to maximize the efficiency of the wastewater treatment of the present invention, and may be omitted in consideration of the installation area, the cost aspect, or the processing time. Of course.

In addition, the wastewater treatment apparatus 100 mixes the wastewater introduced from the water collecting tank 110 and the ionized gas generated by the ionizing gas generating step to generate a gas-liquid mixture (S120). At this time, the wastewater treatment apparatus 100 uses the gas tank 122 to prevent backflow of the gas-liquid mixture generated in the gas-liquid mixture generating step S120 (S130).

At this time, the wastewater treatment apparatus 100 can control the power applied to the electrode rotation bar 30 and the internal electrode wall 20 to adjust the height of the brush 60 installed to move up and down the electrode rotation bar 30 S150). In this case, the brush 60 moves upward due to the rotational force of the electrode rotation bar 30, thereby scraping foreign substances adhering to the internal electrode wall 20.

The wastewater treatment apparatus 100 moves the gas-liquid mixture discharged from the housing 10 of the electrolytic cylinder 140 along the set path of the irradiation path tube 146 (S160). At this time, the wastewater treatment apparatus 100 generates resonance cavity oscillation output of a magnetic pole including electromagnetic waves and energy by using an electron irradiation apparatus, and concentrates the generated electromagnetic wave and energy at a set position of the irradiation path tube 146 (S170).

The wastewater treatment apparatus 100 reflects the electromagnetic wave and energy transmitted through the irradiation path tube 146 using the reflector 157 and transmits the electromagnetic wave and energy to the gas-liquid mixture passing through the inside of the irradiation path tube 146 (S180).

The wastewater treatment apparatus 100 separates the gas-liquid mixture passing through the irradiation passage pipe 146 into treated water and foamed sludge and discharges it (S190).

As described above, the wastewater treatment apparatus 100 can treat waste wastewater using the electrolytic cylinder 140 and the electron irradiation apparatus, thereby improving the efficiency of wastewater treatment.
