Description

Soil restoration system using integrated electrode module and its method {ELECTROKINETIC SOIL RECOVERY SYSTEM USING OF ELECTRODE MODULE AND METHOD THEREOF}

The present invention relates to an electrokinetic soil restoration system and method thereof, and more particularly to the formation of poles symmetrically around a positive electrode, thereby reducing the heavy metals and salt ions of the large-area cultivated soil with low voltage. The present invention relates to an electrodynamic soil restoration system and a method for removing and restoring the same.

Soil can be contaminated by various harmful substances such as heavy metals, phenols and oils. These soil contaminants accumulate in crops and contaminate groundwater, which eventually harms human health.

In order to solve this problem, electrokitnetic soil recovery techniques have been studied a lot, and the basic principles will be described below.

Supplying direct current electricity to wet soil improves the desorption and dissolution of pore water to contaminants as it moves through the electrophoresis, electroosmosis, electrophoresis, and electrolysis of water. It increases the solubility and mobility of pollutants.

However, in high pH areas, such as soils near the cathode side, adsorption and precipitation reactions predominate, resulting in reduced mobility of contaminants. Contaminants present in the pore water are removed from the soil by mechanisms such as electrophoresis, electroosmosis, and diffusion. Positively charged contaminants are transported to the cathode by complex transport mechanisms such as electrophoresis and electroosmosis. On the other hand, the electrophoresis of negatively charged contaminants is reduced by electroosmosis in the opposite direction.

Figure 1 shows the basic principle of the electrokinetic soil restoration technology. The strength of the electric field mainly applied to electrokinetic soil recovery techniques is 10-200 V / m (Prostein and Hicks, 1993), and the current density is 1-10 A / m ² . When the soil is restored by applying electrokinetic techniques, the movement direction and removal efficiency of pollutants are affected by various factors. The representative ones are pollutant concentration and mobility, soil type and structure, and pore fluid. Chemical reactions and electrical conductivity of pore fluids that occur at soil and soil interfaces (Virkutyte et al., 2002).

Most studies of electrokinetic techniques to date have demonstrated that the major contaminant removal mechanism is electrophoresis. However, a study to remove cadmium and lead from Milwhite kaolinite performed by Hsu (1997) and suggested that Kim et al. Could act as a dominant removal mechanism over electrophoretic mobility. When soils contaminated with heavy metals are restored using electrokinetic techniques, if the soil surface has a negative zeta potential, the electrophoresis of heavy metals is enhanced by electroosmosis, effectively removing heavy metal contaminants.

However, when the electrokinetic process is applied, the overall soil pH decreases as the acid wire generated at the anode moves. This decrease in pH increases the mobility of heavy metal contaminants, creating a favorable environment for heavy metal removal, but adversely affects heavy metal removal by reversing the electroosmotic direction by affecting the polarity of the zeta potential. Therefore, in order to effectively remove heavy metal contaminants, the pH should be kept as low as possible in order to increase the solubility, and at the same time, the pH should be adjusted as high as possible to maintain the negative zeta potential. Hydrogen ions produced at the anode move toward the cathode by means of electrophoresis, electroosmosis, diffusion, etc. These groups of hydrogen ions are called acid fronts.

As the premature wire moves towards the cathode, it reduces the pH of the soil, thereby controlling the desorption and dissolution of heavy metal contaminants in the soil. On the other hand, a group of hydroxide ions produced at the cathode form an alkaline or base front, and the base is moved toward the anode. In contrast to premature lines, base lines move in the soil, increasing the pH of the soil, and in particular, depositing heavy metal contaminants in soil close to the cathode side.

Therefore, the ante-conductor acts as an advantageous mechanism to remove the contaminants by converting heavy metal contaminants into a highly mobile form, but the base wire has an adverse effect on the removal of contaminants by adsorbing or sedimenting the contaminants in the soil. Go crazy. Of course, decreasing the pH of the soil can result in reduced electrostatic osmotic flow or reverse electroosmosis, which can interfere with the removal of heavy metal contaminants.

PH, ionic strength of pore water, pollutant characteristics (mobility, solubility, presence form), soil surface characteristics (charge characteristics, size and sign of zeta potential, cation exchange capacity) due to the movement of acid and base lines produced by electrolysis ) Is affected.

The ion mobility of hydrogen ions is about twice as large as that of hydroxide ions, and in the general case where the soil surface is negatively charged, the electrophoretic rate of hydrogen ions increases due to the electroosmotic increase by electroosmotic. Is much larger than hydroxide ions. Therefore, if the anode and cathode are not subjected to special chemical treatment, the ante and base wires move both from the soil to the cathode and the anode, but the movement of the ante wire in the soil predominates and the soil pH decrease is dominant.

Figure 2 is a block diagram showing a conventional electrokinetic contaminated soil purification system. As shown in FIG. 2, electrostatically contaminated soil purification cells 10 and electrostatically contaminated soil purification cells 10 for purifying electrodynamically contaminated soil by applying pulsed power to the contaminated soil are provided. Power supply device 20 for supplying pulsed power, and for supplying the electrolyte solution 32 to the electrokinetic contaminated soil purification cell 10

Referring to FIG. 2, the electrokinetic contaminated soil purification cell 10 is divided into a positive electrode cell P, a negative electrode cell N, and a contaminated soil cell 15. The positive electrode cell P has a concentration of the electrolyte in the positive electrode housing 12P and the positive electrode housing 12P for accommodating the electrolyte 32 so as to surround the positive electrode 11P and the positive electrode 11P, the conductor to which the positive voltage is applied. It consists of an electrolyte circulation pump (14P) to be constant, the cathode electrode cell (N) is a cathode housing (12N) for receiving the electrolyte 32 to surround the cathode (11N) and the cathode (11N), the cathode housing ( It consists of an electrolyte circulation pump 14N for making the density | concentration of electrolyte in 12N) constant.

Each of the cells P, N, and 15 is separated / connected into the porous cellulose membranes 13P and 13N which are easily permeable to the solution, and in some cases, the ion exchange membranes 16P and 16N on the front surface of the cellulose membrane (the electrode cell direction). ) Can be installed. That is, the anode electrode cell P and the contaminated soil cell 15 are separated / connected to the first porous cellulose membrane 13P which is easy to permeate the solution, and the cathode electrode cell N and the contaminated soil cell 15 are The permeability of the solution is easily separated / connected to the second porous cellulose membrane 13N.

The anode electrode cell P and the cathode electrode cell N can supply the electrolyte 32 separately, and the electrolyte can be maintained by the electrolyte cell 30 using the mariotte bottle. This prevents changes in chickenpox inclination.

In addition, in order to measure the drainage amount of the electrolyte 32 transferred from the anode 11P to the cathode 11N by the electroosmotic phenomenon, a drainage measuring cell 40 (recovery cell) is formed on the cathode, and the anode electrode cell ( In order to minimize the difference in ion concentration between P) and cathode electrode cell (N), electrolyte circulation pumps (14P) and (14N) are implemented, and the electrochemical characteristics (pH, conductivity) and heavy metal ion concentration of electrolytes are easily analyzed. I can do it.

As a power supply source for the positive electrode 11P and the negative electrode 11N, the pulse power supply device 20 is connected to use not only a pulse power supply but also a DC power supply, so that current and The information collecting device 53 is connected to measure the voltage automatically and transmit data to the computer.

That is, the measuring means 50 for measuring the power supply is the information collecting device 53 for collecting information from the voltmeter 51 and the ammeter 52 and the oscilloscope 55 receiving a signal from the probe 54 of the electrode. The power supply characteristics applied between the positive electrode 11P and the negative electrode 11N can be measured. In particular, in the case of the pulse power supply 20, a pulse waveform can be directly observed in an oscilloscope 55 through a separate probe for measuring voltage and current.

This conventional electrokinetic soil restoration system has a disadvantage in that the installation cost is increased to restore the soil by removing heavy metal ions or salt ions since the plantation soil for growing crops has a large area. In addition, since a high voltage causes heating (heating) to generate the same current output, a higher voltage needs to be applied, and therefore, a large amount of energy is required, and the removal efficiency of pollutant ions is reduced.

In addition, it is not easy to install a water pipe for discharging the electrode and pollutant ions, the fixed electrode structure is not easy to repair due to the system failure, there is a problem of high risk of electric shock due to high voltage or current.

The problem to be solved by the present invention with respect to the above problem is to reduce the power consumption when the plantation area to be restored is large, increase the removal efficiency by increasing the mobility of contaminated ions, as well as lower the system cost. To provide a soil restoration system and method using an integrated electrode module that can be easily installed and repaired and can prevent the risk of electric shock.

The soil purification system according to the present invention for solving the above problems is a side electrode module provided with a side electrode inside the straight side waterway pipe formed on both sides of the soil outside the plantation; A central electrode module positioned at the center of the plantation soil and having a central electrode installed at an inner center of a straight central water pipe parallel to the side water pipe, and a power source capable of applying voltage or current to the both and side electrodes; Both side water pipes are made of a non-conductive material.

Here, the shape of the center and side electrodes is preferably a porous plate shape, the shape of the center and side electrodes is preferably a mesh plate shape, the material of the center and side water pipes is preferably PVC.

In addition, preferably may further include a control means for controlling the moisture content of the plantation soil on the plantation soil, the moisture content control means is a moisture content measuring device capable of measuring the moisture content of the plantation soil and the It may be to include a water jet to supply moisture to the soil.

In addition, it is preferable to further include an ion concentration measuring means for measuring the concentration of ions contained in the plantation soil, the interface between the electrode module adjacent to the plantation soil is preferably a porous cellulose membrane, the central electrode is stainless It is also preferred that at least one material be steel or metal oxide.

In addition, the power source is preferably capable of applying at least one of a pulse type, AC and DC voltage, the flow rate adjusting means for measuring the pH of the aqueous solution surrounding the electrode, and adjust the flow rate of the electrolyte in accordance with the measured value It is preferable to further include, measuring the pH of the aqueous solution surrounding the electrode, and if the difference between the pH between the measured amount and the side electrode exceeds a predetermined range by alternating the polarity of the amount and side electrode pH It is preferable to include a pH adjusting means for adjusting the.

On the other hand, the soil purification method according to the present invention comprises the steps of (a) controlling the moisture of the soil under the plantation; (b) applying a voltage or current through a power source connected to an electrode module in which water pipes and electrodes are integrally formed outside the center and both sides of the soil below the plantation; (c) moving positive or negative ions dissolved in the soil below the plantation into the side or center electrode module due to the application of the voltage or current; And (d) discharging a solution comprising the ions introduced into the side or center electrode module.

Here, the step (a) is a step of measuring the moisture content value of the soil, and controlling the water content by spraying water on the soil by at least one water spraying means according to the measured moisture content value, The soil is a salt agglomerated soil, wherein the positive or negative ions are preferably salt ions.

Further, preferably, in the step (b), the voltage may be applied by mixing pulsed, AC and DC voltages, and the step (c) measures the pH of the channel to control the flow rate of the electrolyte. It may include a step, the step of measuring the pH of the solution around the electrode and when the difference in pH between the measured center and side electrodes exceeds a predetermined range to apply a voltage or current by alternating the polarity of the anode It may be to further comprise the step.

When the present invention is provided, it is possible to move and remove pollutant ions from both the center and the center of the soil, thereby increasing the efficiency of removing pollutants at low power, and dispersing the potential difference between electrodes, thereby increasing the area of cultivated soil. It can also be applied to restoration.

In addition, it facilitates the movement of pollutants, eases the pH adjustment by reducing the gradient of pH in the soil, and if the soil is dried by the heat of resistance of the soil, it may cause an increase in resistance during ion migration, but AC or pulse type By applying a voltage, the ions adsorbed in the soil can be easily desorbed to facilitate movement, thereby increasing the removal efficiency and providing a rest period to prevent drying of the soil.

In addition, it is easy to install and repair the system by employing an integrated electrode module, and there is an advantage to prevent an electric shock due to high voltage or current around the electrode.

3 is a view illustrating a side configuration of a soil restoration system using an integrated electrode module according to the present invention, and FIG. 6 is a diagram illustrating a flowchart of the restoration method. Hereinafter, a soil restoration system and a method using the integrated electrode module according to the present invention will be described by comparing FIGS. 3 and 6.

As shown in FIG. 3, the soil restoration system includes a straight channel and side electrodes on the outer side of the central electrode module 110 and a plantation facility (eg, a vinyl house) 133 including a central channel and a central electrode in the center of the plantation soil. The side electrode module 120 including the 125 is formed, and the center electrode 115 and the side electrode 125 are connected to apply a current or a voltage.

That is, the system includes a central electrode module 110 in which the central water pipe and the central electrode 115 are integrated, a side electrode module 120 including the side water pipe and the side electrode 125, and a power supply 150 for applying voltage / current. ), The water content control means (130, 135), the ion concentration measuring means, the electrolyte flow rate adjusting means (140).

In other words, the soil under the facility 100 for growing crops, such as a house, contains a large amount of heavy metals or salt ions due to various fertilizers or pesticides. In order to solve the problem of contaminating or damaging the soil 100 and causing the contaminated crops to be produced or reducing the yield, the soil 100 is to be restored to a system having the same configuration as the present invention.

Common soils include heavy metals, radioactive materials, inorganic pollutants such as toxic anions and organic pollutants such as acetic acid, petroleum hydrocarbons, halogens and non-halogen hydrocarbons, and salt ions. The present invention relates to a soil restoration system that removes detected salt ions (Ca 2+, Na +, K +, Cl −, NO 3, etc.), but of course, other contaminated ions can be removed.

As shown in Figure 3, the soil restoration system using the electrokinetic (Electrokinetic) according to the present invention forms a central electrode module 110 in the center of the soil under the plantation facility, the side electrode is mounted on the outer side of the facility inside the water pipe When the side electrode module 120 formed integrally is applied to apply a voltage or a current, the electric field is symmetrically opposed to the center electrode. That is, the polarities of the side electrodes and the center electrodes are arranged opposite to each other to form an electric field, and the polarity may be selectively taken as positive or negative.

The soil restoration system configuration according to the present invention shown in FIG. 3 may facilitate installation and repair of the system by integrating the electrode and the water pipe which is a passage for removing the contaminant ions, and may be generated due to the high voltage or current applied to the electrode. There is an advantage to prevent the electric shock. That is, the housing of the water pipe can be made of a non-conductive material to block the leakage current from the electrode and the electrolyte solution, and the electrode can be easily removed from the module to facilitate the repair in case of system failure, as well as the installation thereof.

Looking at the contaminant ion removal process in more detail through such a configuration (see FIG. 6), first adjust the moisture content so as to contain a certain moisture in the planting soil 100 (S100), the contamination in the plantation soil 100 When voltage or current is applied to both electrodes in a state where the ions are dissolved and dissociated (S200), the cations move to the cathode and the anions move to the anode due to the electric field (S300). By discharging the accumulated solution of each electrode module (S400) to restore the soil.

The movement of ions is called electrophoresis, and electrophoresis is called electrophoresis, in which concentration gradients of ions are formed by electrophoresis and water or colloidal particles are induced. That is, the system according to the present invention is a soil restoration system that removes contaminated ions by moving and accumulating contaminated ions around the electrodes of the anode and cathode by electrophoresis and electroosmotic, and discharging them together with water.

In this case, the electrode is preferably made of stainless steel or metal oxide, which is preferably made of an insoluble material that does not easily oxidize, since the electrode is in continuous contact with the electrolyte solution or water and is easily oxidized and corroded. Do.

In addition, each of the electrodes 115 and 125 may have a plate shape, more preferably a porous plate shape or a mesh plate shape. This is because the surface area is wider than that of a general plate shape, thereby making it easier to move ions according to polarity, thereby increasing the removal efficiency of contaminated ions.

4 is a view illustrating the shape of an electrode module which is a component of the soil restoration system according to the present invention. As shown in FIG. 4, plate shape (FIG. 4 (a)), porous plate shape (FIG. 4 (b)), mesh plate shape (FIG. 5 (b)), etc. can be employ | adopted as an electrode.

Porous plate (Fig. 4 (b)) electrode or mesh plate (Fig. 4 (c)) electrode has a larger surface area than the general plate shape to reduce the contact resistance of the electrode, the heating of the electrode due to the application of voltage or current It can reduce the power efficiency. The outer housing of the water pipe is preferably made of a non-conductive material. For example, it is also possible to be a PVC material. This is because the risk of electric shock caused by the application of high voltage or current is prevented and the durability of the electrode module is increased.

In addition, it is preferable that the surface of the electrode module illustrated in FIG. 4 in contact with the soil is formed of a porous cellulose membrane, which prevents soil particles from entering the electrode module and allows only ions or water to move or pass through. This is because the efficiency of the removal is increased.

Water content control means is composed of at least one water injection unit 130, and a water content measuring device 135, the water content measuring device 135 measures the water content of the soil, the water is not the most efficient water content range By allowing the water to be supplied through the injection unit 130, the moisture content of the soil may be controlled. That is, a certain amount of water is present in the soil, so it is possible to control the moisture content and permeability control in the soil to dissolve the ions adsorbed on the surface of the soil in the liquid phase to be moved by the electric field.

Here, the water spray unit can be sprayed by being located on the top of the soil as shown in FIG. 3, and can be sprayed by installing a porous pipe inside the soil (not shown).

The main soil properties that affect the efficiency of the electrokinetic soil restoration process are chemical, mineralogy, structural properties, zeta potential, and water content. The water content (saturation) influences the electroosmotic flow rate. This affects process efficiency. During the electrokinetic process, negative pore pressures may occur, resulting in areas where the distribution of pore water in the soil is irregular or where consolidation occurs. Negative pore pressure can be caused by irregular electric osmotic flow as the pH, field strength, and zeta potential change locally in the soil.

Such irregular water content distribution of the soil not only increases the electrical resistance in the soil, but also adversely affects the movement of pollutants, thus affecting the process efficiency. In the present invention, the moisture content and distribution are appropriately controlled through the moisture content control means. By doing so, it is possible to increase the contaminant ion removal efficiency.

As shown in Figure 3, the ion concentration measuring means for measuring the concentration of ions contained in the cultivated soil further comprises a means for measuring the concentration of contaminated ions, because the concentration affects the removal efficiency It is configured to measure and control.

If the concentration of pollutant ion (i.e., the concentration of pollutant) is more than the soil adsorption capacity or ion exchange capacity, the removal efficiency is high.However, the concentration of pollutant is low, so that the mobility due to soil adsorption, ion exchange Lowering will reduce process efficiency. Process efficiency depends not only on the concentration of pollutants to be removed, but also on the concentrations of other species present in the soil. If the concentration of the non-removable species is higher than the concentration of the pollutant to be removed, the electrical efficiency of the pollutant is reduced, and thus the removal efficiency of the pollutant to be removed is reduced.

Therefore, by providing an ion concentration measuring means for measuring the concentration of contaminated ions of the plantation soil connected to the terminal 155 shown in Figure 3 it is possible to increase the electrical efficiency and removal efficiency.

As shown in FIG. 3, the cultivated soil and the adjacent surfaces of each electrode module 110 and 120 are separated and connected to a porous cellulose membrane that is easily permeable to the solution. In some cases, an ion exchange membrane is disposed on the front surface of the cellulose membrane (the electrode cell direction). It can also be installed. By doing so, the mobility of the ions can be increased to increase the removal efficiency (not shown).

Moreover, it is preferable that the width | variety of the water pipe of each electrode module is 0.5-1 m, and it is preferable that the depth of the water pipe is 0.3-0.5 m. By forming a water pipe having such a depth and width, it is possible to efficiently remove and drain the contaminated ions transferred to the electrode. Of course, depending on the area of the plantation can have a suitable depth and width of the water pipe.

In addition, an electrolyte flow rate control means is provided to statically control the pH of the electrolyte filling around both electrodes 115 and 125, which adjusts pH and zeta potential and desorptions for the purpose of increasing the mobility of contaminating ions. This is because the electrolyte flow rate of the positive electrode and the negative electrode electrolyte solution can be controlled in order to facilitate the increase of the electrical osmotic flow rate.

In addition, when a voltage or current is applied to the anode and the cathode, the pH is increased at the cathode and the pH is decreased at the anode. In the present invention, when the pH gradient is increased, by controlling the pH by alternating the polarities of the anode and the cathode, contamination The mobility and removal efficiency of ions can be improved. That is, the pH is measured by measuring the pH of the solution filled in the channel through the pH measurement means, and when the difference in the pH of the measured positive electrode is more than a certain range by changing the polarity of the positive electrode to drop the concentration gradient.

On the other hand, as shown in Figure 3, the central electrode 115 and the side electrode 125, the power supply 150 that can apply a current or voltage is connected to the electrode, the application of an appropriate voltage or current is ampere Through the ampere meter (A) and the voltage meter (V), it is possible to apply the highest voltage or current with the highest removal efficiency.

The power supply 150 shown in FIG. 3 is a device capable of applying a DC voltage as well as a pulsed voltage and an AC voltage. In general, DC voltage or current is generally applied in the general rehabilitation system using an integrated electrode module. However, when the area of the plantation soil to be restored is large, high power is required, and the movement speed of the pollutant ion is slow. There was this.

In order to improve this point, by applying the waveform shown in FIG. 5 by mixing a pulsed voltage, a DC voltage, and an AC voltage as an embodiment according to the present invention, power and removal speed efficiency can be improved.

In other words, in the case of the conventional DC or pulse, the voltage or current is supplied in one direction, and the pulse is a current on / off concept. In the embodiment of the invention, by combining the pulse and DC / AC, patterning it to maximize the efficiency. As shown in FIG. 5, the pulse type voltage, the DC type voltage, and the AC type voltage may be sequentially applied to increase the energy efficiency and the removal efficiency. The pattern of the applied voltage illustrated in FIG. 5 is only one example, and the pattern is not limited.

In detail, if the polarizer is kept at one polarity by applying a conventional DC voltage, by-products are generated around the electrode (particularly, the cathode), which may interfere with the flow of current, thereby acting as a factor of increasing the resistance, but the present invention shown in FIG. By applying a reverse pulse or AC as in the embodiment of the by-products can be suppressed, it is also effective to remove the generated by-products.

Therefore, providing the present invention facilitates the movement of pollutants, eases the pH control by reducing the gradient of pH in the soil, and may cause a rise in resistance when the soil is dried by the resistance heat of the soil. However, by applying AC or pulsed voltage, it is possible to provide a rest period to prevent drying of the soil.

As described above, the soil restoration system and the method using the integrated electrode module according to the present invention allow removal of pollutant ions from both the center and the center of the soil, rather than the conventional two-electrode structure, by removing the removal efficiency at low power. In addition, it is possible to increase the potential difference between the electrodes and to apply to the restoration of large-area plantation soil.
