The present invention relates to a wastewater treatment system using a redox metal reactor,

More specifically, it is possible to electrochemically treat oil-based wastewater, acid and alkali wastewater, livestock wastewater, food wastewater, various oil-based wastewater (ideally difficult to decompose wastewater), and other wastewater discharged after being used for metal surface treatment in steel mills. Treatment using redox metal reactor filled with two or more metal media with potential difference, especially pre-treatment or post-treatment, causes the oil contained in sewage water to float together to thicken the top surface of the treatment tank, and further to unite by saponification reaction It solves the problem that the separation of oil and water treatment becomes impossible, and also the sterilization effect (strong sterilization and oxidation, bacteria and algae) in normal water treatment process (wastewater treatment, seawater desalination plant, water such as cooling water) Additional functions such as blocking the source of occurrence, preventing corruption, removing odor, preventing scale and rust In addition, the present invention relates to a sewage treatment system that can achieve true high altitude water treatment and further maintain the performance of the redox metal reactor using pH meter and ORP (Oxidation-Reduction Potential Meter).

Oily wastewater from waste oil discharged after being used for metal surface treatment in steel mills, acid / alkali wastewater from industrial complexes, livestock wastewater, oil, especially food wastewater containing large amounts of animal oil, and other wastewater In the aeration process, it is easy to combine with microorganisms or the like for a variety of reasons, so that the particles grow together, float together, or close the pipeline, and in particular, when a saponification reaction occurs during various causes such as a chemical treatment process, sewage or sewage treatment becomes almost impossible.

High concentrations of sewage, in particular, significantly increase the COD and cause significant odors when the oil particles oxidize.

In addition, food waste water has a high proportion of animal fats and solidifies at low temperatures, causing severe blockages in storage facilities and transfer pumps.

In addition, it is common to treat high concentration organic wastewater by anaerobic digestion process, which causes excessive problem of facility cost and maintenance cost.

In order to treat conventional high concentration organic wastewater,

However, ozone, plasma and electrolysis water treatment methods may be suitable for use as a post-treatment means to assist in the removal of color and odor after biological treatment or chemical treatment, but are not suitable for pretreatment or main wastewater treatment. The reality is not enough, even considering the increase in size and excessive operating costs.

Used together to increase the purification of high concentration wastewater,

The concrete composition provides a method for treating high concentration wastewater by mixing with an oxidizing agent to hydrolyze and then neutralizing, denitrifying and flocculating by adding a base agent and a suspension liquid for ammonia dissociation to the reaction product. By hydrolysis, the colloidal substances in the wastewater are reorganized into tissues and are easily separated into solid-liquid, and the dissolved organic and inorganic substances induce phase transformation catalysis, which precipitates as a solid. The denitrification by the reaction and the denitrification by the copper contact catalytic reaction can be carried out to purify the high concentration wastewater quickly and economically.

Therefore, this patent technology is also difficult to treat large discharged waste water, especially organic, oil-containing waste water, and the copper contact catalyst, after all, like the above-mentioned prior art as a post-treatment means, has a secondary function in water treatment.

In describing the wastewater treatment system (A) using the redox metal reactor according to the present invention, for the sake of convenience, a non-strict approximate direction reference is made with reference to FIG. 1, from the inlet part 10 to the settling tank 50. Determine the front and rear for the subsequent treatment route of wastewater.

As shown in Figure 1, the sewage treatment system (A) using a redox metal reactor according to the present invention is an oily wastewater discharged after being used for metal surface treatment in a steel plant, acid and alkali wastewater generated in an industrial complex, Livestock wastewater, food wastewater, various oily wastewater (ideally hardly degradable wastewater), inlet 10 for supplying to the system for treating other wastewater, retention tank 20 connected to the inlet to ensure stable water treatment, A redox metal reactor 30 for receiving and treating wastewater from a retention tank, a chemical treatment tank 40 for chemical treatment of high concentration wastewater, and a pH meter provided at the rear of the metal reactor to confirm treatment performance of the metal reactor, It includes an ORP meter (not shown).

However, the sewage treatment system using the redox metal reactor according to the present invention separately separates the 'by-pass path' (circulation pipe 30a, so as to be suitable for treating a high concentration of oily wastewater or various high concentration wastewater as shown in FIG. 1). Through the 30b)) to separate the redox metal reactor from the treatment line to implement the wastewater treatment system,

It can take the 'on-line route' installation method, which directly arranges the redox metal reactor on the main treatment line, which can be suitable for the treatment of relatively medium and low concentration oily wastewater or sewage water,

In addition, as shown in FIG. 1, a redox metal reactor is installed for pretreatment, or arranged behind the water treatment line to prepare a post-finish post-treatment ('on-line path' or 'by-pass path'). Method is preferred).

In conjunction with other biological and chemical treatments, the redox metal reactor may be arranged in the middle of the water treatment process.

Therefore, the present invention should not be construed as limited by the description of the following oily wastewater, in particular, oily oily wastewater treatment, pretreatment, and 'by-pass path' arrangement of the redox metal reactor.

In FIG. 1, the inlet 10 may also include a sampling tank 13, and the sampling tank 13 is provided with various water quality meters such as a pH meter. It is used as a basic value to detect the processing performance of the metal reactor by detecting the signal, and is also transmitted to a controller C (not shown, such as a connecting cable), which is composed of a programmable logic controller (PLC). The amount of the chemicals or the treatment agent added to the treatment tank 40 may be varied so that the optimum water treatment process may proceed.

The retention tank 20 is connected to the inlet to ensure a stable water treatment, in particular, in order to ensure a more complete pretreatment of high concentration sewage waste water (redox) metal reactor 30 and the retention tank and the circulation pipe (30a, 30b) It is preferable to repeat the treatment of wastewater.

In addition, the retention tank 20 is provided with a scum skimmer 21 to filter out oil particles including foreign matters, and to perform the stirring function as well as the aeration function of the compressor 23 as a compressor ( 23a) and diffuser 23b are provided.

The discharge side of the retention tank 20 is provided with a baffle to discharge the floating foreign matters, in particular oily foreign matters and to perform the function of a weir (weir),

Overflowed foreign matters are discharged through the discharge portion 25, and then incinerated or transferred to a third place through a tank lorry to be processed.

The holding tank 20 is also equipped with a water level measuring means, in particular a level transmitter (G), so that the amount of supply at the inlet 10 through the level measurement of the holding tank, subsequent processing through the transfer pump 27 It is linked to control the discharge amount, the supply amount to the redox metal reactor 30 through the supply pump 31, the valve or pump of the inlet portion 10, the feed pump 27, the feed pump 27 of the inlet via the signal line (G1) 31 and the controller C.

The wastewater treated by the redox metal reactor 30 is discharged for subsequent treatment through the transfer pump 27, and is supplied to the auxiliary retention tank 28 through the transfer pipe 27a, or the direct delivery pipe 27b. It can be supplied to the chemical treatment tank 40 through.

The auxiliary retention tank 28 has a high solubility of the wastewater, or the oil is not completely treated by the redox metal reactor 30, or when the oily wastewater is not treated, or when there are a lot of floating foreign matters. An oil skimmer (28A) is provided.

A discharge pump 29 is provided on the discharge side of the auxiliary holding tank 28, and a conveying pipe 29b is provided to allow repeated shaking by an oil skimmer, if necessary, and chemical treatment. A feed pipe 29a for supplying the cooking wastewater is also provided.

The auxiliary holding tank 28 is also provided with a level measurement means, in particular a level transmitter (G), which controls the proper amount of transfer while communicating with the rear transfer pump 29 via the signal line G1. In addition, the oily foreign matter and the like collected by the oil skimmer (28A) is also discharged through the discharge portion 25, and then incinerated or transferred to a third place through the tank lorry to be processed.

On the other hand, the redox (redox) metal reactor 30 corresponding to the core of the present invention is connected to the plurality of circulation pipes (30a, 30b) in parallel in order to ensure the treatment capacity, if necessary, even in one wastewater circulation Multiple metal reactors can be configured in series with one line for more complete processing.

Oily wastewater discharged after being used for metal surface treatment in steel mills, acid and alkali wastewater, livestock wastewater, food wastewater, and other high concentration wastewater from industrial complexes has a unique oil content and wastewater. It can be thought of as processing.

However, in the case of sewage water containing a high concentration of oil, it is agglomerated and injured due to the specific granulation and combination of oil components to block the pipes and pumps, and the oil and water separator itself cannot function. As it floats and covers thicker (several centimeters), sewage treatment itself becomes impossible. In addition, the saponification reaction, etc. in the various causes and treatment process is impossible to transfer itself, causing a failure in the pump or the treatment device, it is simply impossible to process by oil water separator.

In particular, oily wastewater from waste rolling oil, etc., in steel mills is almost completely carbonized and discharged, and thus, it is easy to fall into a situation in which even the initial operation of the water treatment process is impossible by a general known treatment method.

The oil organic particles are treated with a redox metal reactor filled with two or more metal media having an electrochemical potential difference to emulsify (emulsify) and oxidize them so that they can be transported and processed in a subsequent chemical treatment tank 40. It is important to make.

In the present invention, when a severe oily wastewater is decomposed and pretreated using a redox metal reactor, the chemical treatment efficiency is greatly increased due to oxidation and decomposition.

Two or more metal media with electrochemical potential differences can also be referred to as galvani potential differences, the potential differences of dissimilar metals.

The redox metal reactor 30 includes a metal oxide (a kind of electrode) and a reducing metal (a certain electrode) that generate electrons while being oxidized, and electromotive force is generated by a potential difference.

Such dissimilar metals may be aluminum, zinc, copper, silver, magnesium, or the like, or alloys thereof.

Dissimilar metals that provide self-redox, reduction-oxidation functions such as Co, Ni, Sn, Fe, Al, Ag, Mn, Cu, and Zn are used in sewage, essentially in contact with oil-containing particles. While improving the castle, it is necessary to ensure the passage of sewage water, either made of porous structure, or simply assembled with a thread (two or more metals with an electrochemical potential difference) and arranged in a housing similar to a pulley, A cap having a nozzle may be coupled to both ends of the housing, and the circulation pipes 30a and 30b may be coupled to each nozzle and installed.

Since the redox metal reactor 30 is composed of two or more metal particles having an electrochemical potential difference from each other, the redox metal reactor 30 spontaneously causes a redox reaction with the oil-containing particles contained in the wastewater without applying power from the outside. Decompose the contained particles. Heterogeneous metal media, which act as anodes and cathodes, respectively, are self-redox, reduction-oxidation reactions (redox reactions) because water, oil-containing particles, and other foreign substances in sewage water act as electrolytes. .

More specifically, the oxidation reaction is a reaction of losing electrons or obtaining oxygen, and the reduction reaction refers to a reaction of gaining electrons or losing oxygen, as opposed to the oxidation reaction, and redox refers to oxidation and reduction reactions. Therefore, the redox metal reactor 30 according to the present invention causes an electrochemical reaction in the process of transmitting and receiving redox reactions at the same time to act as sterilization, scale prevention, rust prevention, odor removal, and the like.

First of all, the sterilization effect is explained when the oxidation catalyst reaction occurs during the sterilization action. In the process of the oxidation catalyst reaction, the material releases electrons through oxidation, which acts on cells of bacteria and bacteria, and hemolysis of the cell wall. This action is to kill the bacteria, and the released electrons react with water to produce hydrogen radicals, and hydrogen radicals (· H) react with water to produce hydroxyl radicals (· OH). The radical has a strong bactericidal power, which is about 800 times that of chlorine (Cl). In addition, hydroxyl group (OH-) is generated in the course of the oxidation catalyst reaction, and the pH increases due to the hydroxyl group, and when the pH is 9.5 or more, various bacteria, microorganisms, Sterilization of fungi such as legionella is possible.

In addition, the redox metal reactor 30 prevents the generation of scale. In general, the scale is charged with a pipe wall due to various reasons in the flow of fluid, and fine particles of calcium carbonate, such as fine calcium carbonate, are attracted to the charge. It is formed while attaching to the pipe wall. However, the redox metal reactor 30 provides charge (e-), which is a nucleus of scale formation, in the solution so that the scale to be attached to the pipe wall forms crystals in the liquid to coarse particles. By doing so, it is possible to fundamentally prevent the scale from adhering to the pipe wall.

Furthermore, due to the reduction reaction of the redox metal reactor 30, iron is prevented from rusting, reducing rust, preventing corrosion of pipes, and removing rust that has been generated.

In addition, the redox metal reactor 30 serves to remove odor generated in the sewage water, and has an excellent effect in decomposing odor-causing substances of hydrogen sulfide and aldehydes generated in the waste water during the reaction of the redox metal reactor 30. In addition, the effects of the odor-inducing substance are decomposed through the reaction and the effect can be immediately known and maintained for a long time.

As shown in FIG. 1, the shear circulation pipe 30a is provided with a feed pump 31 so that the wastewater in the retention tank 20 is supplied to the redox metal reactor 30, and the flow meter 30c. By this, the supply amount is kept constant and controlled, and the pump 31 and the valve 31a are controlled by communication with the water level gauge G provided in the holding tank 20.

Furthermore, the pre-filter 33 is provided before the redox metal reactor 30 to remove the overload and the closing problem of the redox metal reactor 30 through the primary removal of foreign matter. have.

In addition, bypasses 33a and 33b used for emergencies are provided to protect the redox metal reactor 30 and the wastewater treatment system A.

Repeated treatment of the wastewater through the circulation pipes 30a and 30b is controlled by the controller C on a time or number basis, and redox (redox) with a pH meter, an ORP (Oxidation-Reduction Potential Meter), and other water quality sensors. It is preferable to install at the front and rear ends of the metal reactor 30 and to read and control these signals.

In addition, it is preferable that the redox metal reactor 30 is provided with a regeneration means 35 in order to extend the use time and to ensure continuous wastewater treatment.

The regeneration means 35 may be a backwash part (not shown) and a steam supply part 35B.

The backwashing unit supplies water in a direction opposite to the water treatment flow direction to clean and regenerate the redox metal reactor 30. The backwashing water may use treated water discharged from the settling tank 5. Basically, it consists of a pressurized pump and a separate storage tank (if necessary) for smooth supply of water. After backwashing the treated water can be disposed of separately or sent back to the holding tank.

In addition, the steam supply unit 35B may be used before or after the operation of the backwashing unit, or may be used simultaneously, and may be used independently. The steam supply direction is irrelevant in both the forward and reverse directions, but is arranged to be supplied in the reverse direction in FIG. 1 in consideration of space utilization and the like.

In addition, the regeneration means 35 preferably further includes a pressurized air supply part 35c, which may be configured as a compressor, a pressurized air storage tank, or the like.

The pressurized air supply part 35c may be used before or after the use of the back detail part or the steam supply part 35B, and performs a whisk function.

Next, the chemical treatment tank 40 may be connected to the direct delivery pipe 27b of the retention tank 20 or may be connected to the transfer pipe 29a of the auxiliary retention tank 28.

The chemical treatment tank 40 is almost the same as a known structure, and has first to third treatment tanks 41, 43 and 45, and each treatment tank includes a stirrer 47 and a pH meter 49. It is.

The first treatment tank 41 receives quantitatively supplied inorganic coagulants such as PAC (polyaluminum chloride) from the first treatment agent supply unit 42, and the second treatment agent 43 receives caustic soda from the second treatment agent supply unit 44. Is supplied in a quantitative manner, and the third treatment tank 45 receives a quantitative supply of a polymer, etc., a coagulation aid, in the third treatment agent supply unit 46.

Subsequent to the chemical treatment tank 40, sludge or the like is precipitated and removed through the sedimentation tank 50 in the rear stage, and the supernatant water is discharged through further treatment such as ozone treatment or the like.

The cleanest treatment water may be discharged through the first discharge unit 51, and the floating matter floating on the upper part of the settling tank may be incinerated or dehydrated by walking with a second discharge unit 53 by walking with a scum skimmer.

The lowest sludge is discharged through the second discharge part 55 and is treated at a third place or the like through dehydration or the like.

One of the other cores of the wastewater treatment system (A) using the redox metal reactor according to the present invention is that the performance of the redox metal reactor is constantly maintained using a pH meter and an ORP (Oxidation-Reduction Potential Meter). will be.

pH meter, ORP meter may be arranged before and after the redox metal reactor (30),

First, the first ORP meter provided in the inlet part 10, in particular the sampling tank 13, or both, the second ORP meter provided on the discharge side of the holding tank 20 and the auxiliary holding tank 28, and the settling tank. It may be composed of a third ORP meter provided on the discharge side of the (50).

If necessary, the second ORP meter may determine whether the redox metal reactor 30 maintains its performance or whether the regeneration means 35 needs to be operated.

To further expand the concept of the ORP meter, various water quality measuring instruments such as pH meters and conductivity meters are arranged before and after the redox metal reactor 30, and the measured values of these measuring instruments are controlled by a controller ( It can be configured to transmit and read to C) to operate the wastewater treatment system A more fully or automatically.

On the other hand, in the high concentration organic wastewater treatment system A using the redox metal reactor according to the present invention, shown in Figure 1, the pump of the backwash portion constituting the regeneration means 35, the compressor of the pressurized air supply unit 35C, In order to turn on / off the electrical equipment such as the pump of the steam supply unit 35B, the agitation function of the holding tank and the aeration function, the compressor 23a of the agitation means and the lighting lamp of the other wastewater treatment system, etc. A switch provided, in particular a wireless switch 60 can be utilized.

In addition, the pump of the backwash portion constituting the regeneration means 35, the compressor of the pressurized air supply unit 35C, the pump of the steam supply unit 35B by the wireless switch 60 to turn on / off these electric operation components. In order to perform the agitation function and the aeration function of the holding tank, the compressor 23a of the agitation means and the lighting lamp of the other wastewater treatment system are preferably provided with a wireless control signal receiver.

The wireless switch 60 can be seen in its specific configuration in FIGS. 2 to 5, the core of which is a diagram relating to a self-generator for more complete wireless control of power operated components.

In describing the self-generator 100, for the sake of convenience, the non-strict approximate direction reference is specified with reference to FIGS. 2 to 5 to divide the top, bottom, left and right in the state as shown.

The development of a switch to turn on / off control of the power element by the wireless self-powered method has been proposed for a long time, and the small self-generator using permanent magnet and induction coil corresponds to a much older technology.

For example, Korean Patent Publication No. 2004-0031713 (April 13, 2004) [Magnetic Power Switch Drive System], Korean Patent Publication No. 2004-0036734 (April 30, 2004) [Switch Magnetic Device], Korea Patent No. 0862175 (October 01, 2008) [Micro-magnetic latching switch with relaxed permanent magnet alignment condition], Republic of Korea Patent Publication No. 2009-0113941 (November 03, 2009) [Light fixture off, off Remote control device]. However, the marketability has not been secured for various reasons, and thus it is not actively applied to everyday life.

The present invention realistically presents a self-generator that enables a wireless switch 60 to be introduced into a sewage treatment system using a redox metal reactor according to the present invention. However, self-generators applied to these switches can be applied for on / off control of electrical actuating components such as transfer pumps or lighting lamps.

The control signal (on / off of the transfer pump or the lighting lamp) can be emitted to the outside by the power delivered to the sensor 181 mounted on the) and transmitted from the end 131 of the induction coil 130.

In addition, the operation panel 170 performs a seesaw motion about an axis,

It is possible that the shaft protrusion 173 under the operation panel 170 is coupled to the fitting shaft 103b provided at the center of the fitting hole 103B of the cover 103 through the shaft groove 173c.

The PCB 180 on which various devices are mounted is provided with a sensor 181 for detecting a pressure and a pressing position applied by the operation panel 170 in response to a seesaw motion and emitting a control signal, However,

The pressure of the operation panel 170 transmitted through the pressing piece 103A of the cover 103 is buffered on the upper part of the PCB 180 and transmitted to the sensor to protect the sensor and enable accurate pressing of the sensor 181 A cushioning pad 105 having a pressing point 105A is covered at that position.

The magnetic body panel 120, the induction coil 130, and the bobbin 133 are soldered to the lower portion of the PCB 180 through the end portion 131 of the induction coil 130 protruded above the bobbin 133, -Shift member 140 assembly < / RTI >
