Description

METHOD OF REACTIVE MATERIALS MODULARAIZATION USED IN THE CONTINUOUS PERMEABLE REACTIVE BARRIERS}

The present invention relates to a reaction wall used to remove contaminants present in the ground, and more particularly, to a reaction material suitable for removing each contaminant when several different contaminants are present together in the ground. The cartridge-type reaction wall is configured to completely remove the contaminants by sequentially aligning the reaction walls in series, and to be easily replaced when the reactants reach a fatigue point that no longer functions. .

Conventional techniques for the reaction wall method for the purification of contaminated groundwater are largely divided into continuous PRBs and funnel and gate-type reaction walls (Funnel Gate ^R PRBs). I am doing it. Here, the reactive reactive barriers method is installed on the ground where the contaminated zone exists and contaminates by inducing the chemical reaction of reactive media and contaminants using the hydraulic flow of the contaminant plume. It says how to get rid of it.

The mechanism by which various reactants react with contaminants is known, for example, as follows.

On the other hand, the mechanisms for the removal of contaminants by the conventionally known reactants such as iron, zeolite, blast furnace steel slag and organic soil are as follows.

First, the mechanism of eliminating chlorinated organics by zero iron is as follows.

In other words, iron (Fe ⁰ ), which is present as a non-ferrous iron, causes oxidation and forms a redox couple. This is similar to the corrosion reaction caused by spontaneous oxidation due to the tendency of the noble metal to lose electrons and to exist in cation form. For iron, the redox potential is -0.44V.

Fe⁰↔ Fe²⁺+ 2e^- Formula (1)

1 is a diagram illustrating the dechlorination process and standard reduction potential of PCE (C ₂ Cl ₄ , tetrachloroethylene). In FIG. 1, the desalination reaction is gradually slowed from B to A. FIG. The point C represents the highest oxidation state and the point D represents the lowest oxidation state. As can be expected from FIG. 1, the main reducing agents capable of reacting with chlorinated organic compounds are Fe ⁰ , Fe ²⁺ , and H ₂ . In the case of the corrosion reaction, mainly by direct electron exchange from Fe ⁰ to alkyl chloride adsorbed on the surface (Equation (2)), the dechlorination of Fe ²⁺ produced by the corrosion reaction (Eq. ), Dechlorination by H ₂ (Formula (4)), or Fe by H ₂ O. The desalination process of alkyl halides (RX) by these reducing agents can be represented by the following equation.

Fe ⁰ + RX + H ⁺ ↔ Fe ²⁺ + RH + X ^- Formula (2)

2Fe ²⁺ + RX + H ⁺ ↔ 2Fe ³⁺ + RH + X ^- Formula (3)

H ₂ + RX ↔ RH + H ⁺ + X ^- Formula (4)

FIG. 2 is a diagram illustrating reductive dechlorination of chlorinated organics by electron exchange due to corrosion of ductile iron. FIG. 2A is a diagram illustrating a reduction reaction of chlorinated organic compounds by zero iron, which occurs directly on the surface of ductile iron, and FIG. 2B is a reduction reaction of chlorinated organic compounds indirectly caused by ferrous ions. 2C is a diagram illustrating the role of zero iron in the reduction of chlorinated organic compounds by H ₂ in the presence of a catalyst.

In the conventional reaction wall method as described above, the granular iron powder was used as it is, without being treated separately or mixed with other components, and thus, the pollutant due to the redox potential of the iron powder was limited. There is a problem that the present invention is limited to materials such as PCE, TCE, DCE, VC, and CT, and cannot be applied to materials requiring high redox capability such as PCBs. In addition, the contaminants containing a high concentration of organic components there was a problem that the surface energy of the iron powder used as the reactant is insufficient to cause sufficient desalination.

Next, the mechanism of removing nutrients and heavy metals by zeolite is as follows.

In other words, zeolite has been known to remove nutrients such as ammonia nitrogen and heavy metals such as cadmium, lead, copper, and zinc from contaminants by ion exchange. Here, ion exchange means that an ion having a charge present in the liquid phase is selectively exchanged with another ion having the same charge present in the solid phase. This exchange reaction enables the separation and removal of specific ions. Ion exchange reactions are stoichiometric and have properties that do not affect the basic structure of the solid being exchanged, allowing for regeneration.

If the ion exchange mechanism is assumed to be a binary system consisting only of specific ions (NH ₄ ⁺ ) in the liquid phase and ions (Na ⁺ ) to be exchanged in the solid phase (Z), the body of the zeolite, for example, clinoptilolite Denotes Z, the exchange reaction between Na ⁺ ions in Z and NH ₄ ⁺ ions in aqueous solution occurs as follows.

Z • Na ⁺ + NH ₄ ⁺ = ZNH ₄ ⁺ + Na ⁺ (5)

Ion exchange occurs at the pore of the zeolite (see pore 30 shown in FIG. 3), and for clinoptilolite, the pore size is known to be 4 kPa.

Next, the removal of suspended solids and sulfates by blast furnace / steel slag and organic soil is as follows. Blast furnace / steel slag removes various colloidal suspended solids through filtration and organic soil removes sulfate through adsorption capacity.

Such a reactant had a problem that it could not be applied to all the pollutants using a single reactant because there was a certain limit to the pollutants that each reactant can remove.

In the continuous wall type reaction wall method, the continuous wall is installed by digging a trench in the anticipated flow path of the contaminated zone and injecting granular iron (Fe ⁰ ). Another installation method is by means of hydraulic fracturing and jetting. The characteristic of the continuous wall method is that the contaminated groundwater can pass through the wall in a natural state without change in flow rate and flow, and because it passes through the reaction wall almost similar to the groundwater flow rate in the underground aquifer, there is a problem such as no contact or bypass. There is no.

In the funnel and gate type reaction wall method, guide barriers are installed to allow contaminated groundwater to flow into the ground. The guide wall is economical by greatly reducing the area of the reactants, while increasing the contact speed of the reactants of the contaminants, thereby increasing the wall thickness so that sufficient contact can occur.

These methods in situ on site by caisson, trench, tremie tube, deep soil mixing, high pressure jetting, hydraulic fracturing, etc. And reactants were mixed at the proper ratio. Therefore, these methods are difficult to apply when the target pollutants contain a variety of materials because of the construction problems such as mixing compaction, maintaining a proper permeability coefficient in the field.

In addition, when the reaction material reaches a fatigue point that no longer exhibits its function, it is difficult to replace, and when excavating for replacement, there is a problem in that contaminated groundwater is discharged as it is during construction.

The present invention is to solve the above problems, consisting of a reactant that can remove the contaminant or convert it into a non-hazardous substance, each of which is contaminated when several different contaminants are present together in the ground A method of purifying contaminated groundwater using cartridgeized reactants that can purify contaminated groundwater with complex components by installing a series of reactants suitable for removing components and standardizing the reactants. And an apparatus thereof.

In Table 1, PCE represents C ₂ Cl ₄ , tetrachloroethylene, TCE represents C ₂ HCl 3, trichoroethylene, and PCBs represent polychlorinated biphenyls.

As shown in Table 1, the types of contaminants that can be purified by the method and the purification system of contaminated groundwater of the present invention are ground pollution factors such as chloride organic compounds, nutrients, heavy metals and sulfates. These will be described in detail below.

Chlorinated organic compounds include PCE, TCE, DCE (C ₂ H ₂ Cl ₂ , dichloroethylene), VC (C ₂ H ₃ Cl, vinyl chloride), CT (CCl ₄ , carbon tetrachloride), trichloromethane (CHCl ₃ )), Dichloromethane (CH ₂ Cl ₂ ), chloromethane (CH ₃ Cl), PCBs and other organic chlorides, such as PCBs, to the electron (electron) generated during the corrosion process of ferrous iron (Fe ⁰ ) Therefore, Cl ⁻ ions are converted into harmless substances such as ethane through a reductive dehalogenation reaction in which the Cl ions are replaced with H ⁺ ions.

In addition, the nitrogen is removed by the microorganisms inhabiting the blast furnace or steelmaking slag and the concentration of nutrients such as phosphorus is reduced by the crystallization dephosphorization mechanism caused by the reaction of CaO and phosphorus of the blast furnace or steelmaking slag. It is characterized in that the impact load is reduced on the zeolite cartridge installed on the rear surface of the reaction wall through which the groundwater passes.

In the method and purification system for contaminated groundwater using the cartridgeized reaction wall of the present invention, the reactant cartridge is a non-woven fabric with a reactant cell located between steel wool piled on both sides, and the induction wall when inserted into the induction wall.

Accordingly, the reactant cartridge may be equipped with a reactant cartridge suitable for removing the contaminant according to the contamination situation in the ground, even if the pollutant changes in the same region over time, simply by replacing only the reactant cartridge Can be.

In addition, when the reactant cartridge needs to be replaced due to aging, only the corresponding reactant cartridge needs to be replaced, not the entire reaction wall. Therefore, even when the reactant cartridge is replaced, the contaminated groundwater can be minimized to pass through immediately without purification.

In addition, the reactant is a wall based on the reactant manufactured by a method of mixing and filling the soil with the reactant at an appropriate weight ratio.

4A is a schematic cross-sectional view of the configuration of a contaminated groundwater purification system of the present invention. As can be seen in FIG. 4A, the gate portion is composed of a reactant cartridge 44 and a guide wall 42 through which the reactant cartridge 44 can be inserted. The reactant cartridge 44 and the guide wall 42 may be provided with uneven parts, for example, a ring and a complementary uneven part, provided with a ring and a guide wall 42, for example, a reactant. It is fixed and installed by having a cartridge fixing socket. The contaminated groundwater flows in the direction of the arrow 46 so that some pass directly through each of the reactant cartridges 44 arranged in series, and some pass through the reaction depletion cartridge 44 by the guide wall 40. Derived.

FIG. 4B is a partially enlarged view showing a portion of the gate portion composed of the reactant cartridge 44 and the induction wall 42 shown by the dotted line in FIG. 4A. As shown in Fig. 4B, the guide wall 42 is provided with an uneven portion, that is, a socket, for fixing the reactant cartridge 44. 4C is a schematic diagram showing the structure of the reactant cartridge 42. As can be seen in FIG. 4C, each cartridge has a reaction wall material 52 including a reactant on a central portion thereof, and a nonwoven fabric 56 (non-wonven) on the front and rear surfaces of the reaction wall material 52. It has a structure stacked with steel wool 58 stacked on both sides with geotextile. In addition, the left and right sides of each cartridge 44, the fixing portion 54 having a structure complementary to the concave-convex portion, that is, the socket 50 installed in the guide wall 42 so that it can be inserted into the guide wall 42 It is installed. The steel wool 58 portion of the cartridge 44 stacked on the nonwoven fabric 56 has a function of filtering suspended matter and a function of purifying organic chloride by steel wool. It is also an effective material for minimizing the gap between the cartridge 44 and the cartridge 44.

The content of the reactant contained in the reaction wall of the cartridge 44 is the highest content within the range that does not show the possibility of closing the gap by reducing the permeability over time when permeate to purify the contaminated ground water It is most desirable to be included. This is because the higher the content of the reactant, the higher the reaction efficiency, but is offset by the decrease in the reaction efficiency due to the decrease in permeability. In general, the reaction wall is preferably contained in the iron or hot-rolled sludge is mixed with soil and the iron or hot-rolled sludge is 5 to 20% by weight, more preferably about 30% by weight. In addition, when the reactant is zeolite, the zeolite is mixed with soil, and the zeolite is preferably contained in an amount of about 5 to 30% by weight, more preferably about 30% by weight. When the reactant is waste lime or limestone, the waste lime or limestone is mixed with soil and preferably contained 5 to 10% by weight of the waste lime or limestone, more preferably about 10% by weight. When the reactant is shot dust or waste foundry sand, the shot dust or waste foundry sand is mixed with soil, and the shot dust or waste foundry sand is preferably contained in an amount of about 5 to 30% by weight, and more preferably, about 30% by weight. . When included in excess of the maximum content% by weight of the reactant decreases the permeability coefficient of the reaction wall over time to significantly reduce the purification efficiency, if included in less than the minimum content% by weight of the reactant Absolute amount is insufficient and purification efficiency is lowered.

On the other hand, when the reactant is selected from blast furnace slag, steelmaking slag, humus soil or weathered soil, the reaction wall is produced without mixing with soil.
