Abstract

The present invention relates to a "purifier of soil oil pollution using tourmaline ionized water".

Soil oil contaminant purifier using tourmaline ionized water is designed to provide eco-friendly surfactant water with high pollutant cleaning power at low cost when applying various soil pollution purification technology using treatment agent.

The most important point in the cleanup of contaminated soil due to oil leakage is to prevent the external spread of the pollution around the oil spill point and to improve the cleanup of the contaminated soil in order to quickly remove and treat the main contaminants in the site. These pollutants remain in unsaturated soil layers or exist in the form of non-aqueous phase liquids (NAPLs) and free products in the saturated saturation layer. DNAPL (Dense Non Aqueous Phase Liquid) precipitated can be treated with contaminated groundwater and amniotic fluid, but oil contamination present in unsaturated zones is more complex and difficult.

Soil flushing is a technique used to treat unsaturated unsaturated oils, and it is possible to increase the fluidity of pollutants remaining in unsaturated zones by adding surfactants or treating agents such as acid / base materials. It is a method of pumping water to the outside by moving to a position.

The cleaning treatment technology injects the treatment agent through the injection well installed in consideration of the soil pollution environment. The treatment agent moves to the surrounding contaminated soil layer through the perforated tube of the injection well and expands its range of action by directly oxidizing or emulsifying the contaminants. The pollutants treated in this way are transferred to a certain area within the site according to the characteristics of Saturn distribution and the flow of groundwater, and are pumped through extraction wells installed at the corresponding points and finally processed on the ground.

Hydrogen peroxide, various surfactants, or ozone water are used as treatment agents for such operations. Until now, surfactants having the function of inducing the natural restoration of contaminated soil by directly or indirectly inducing a biodegradation effect are hydrogen peroxide. It is widely used than chemical oxidation treatment agent that cannot seriously destroy the microbial ecosystem existing in the soil ecosystem such as water or ozone water and cannot expect a natural reduction effect.

However, it is true that surfactants are less toxic to the environment in the soil than hydrogen peroxide or ozone water. However, since they are inherently chemical products, they have their own toxicity values. There is a growing need for environmentally friendly contaminated soil restoration treatments.

In addition, when treated with a surfactant, this can effectively prevent a large amount of unnecessary spillage to the non-contaminated soil in order to maintain an effective contact area with the contaminated soil, resulting in financial loss, and the presence of the injection well The monetary loss is even greater due to the surrounding channel phenomenon. As a result, the amount of treatment required increases, and considering that most of the surfactants used in Korea for the purification of soils are expensive foreign imported products, the cost of purification companies increases, and the purification efficiency decreases due to the difficulty of effective site management. It can only be continued.

In order to solve this problem, the present invention provides an alternative to the need to purchase expensive surfactants by operating a soil oil contaminant purifier using tourmaline ionized water, which can continuously produce ionized water with the same effect as the surfactant, in conjunction with the soil cleaning system. It can be an alternative to solve the difficulty of the company's effective site management due to the cost burden. In addition, the present invention can be efficiently used as a manufacturing facility for the soil cleaning work cleaner based on a similar principle.

The ionized water generation process according to the present invention is as follows.

When the water is contacted with tourmaline using the permanent electrical properties of tourmaline, the water is electrolyzed to separate hydrogen ions (H +) and hydroxyl ions (OH-). ) Combines with the surrounding water molecules to form a surfactant called a hydroxyl (H3O2, Hydroxyl) anion. Since hydroxyl ions exist in an unstable state in water, they rapidly move to the interface to arrange H-O-H groups toward the inside of the water and to arrange H of the O-H groups toward the outside of the water. In this way, the hydroxyl ions are stabilized to act as a surfactant. The present invention can obtain ionized water having a desired amount of surface active power by using groundwater or tap water, which can be easily procured near a work site, without purchasing a commercially available surfactant through a series of ionized water generation processes.

The technical problem to be achieved by the present invention is as described above in terms of the cost of purchasing expensive treatment agents used in the application of various in-situ contaminated soil restoration techniques, including soil cleaning and soil washing, which are the major contaminated soil restoration techniques. By providing an economical and eco-friendly alternative that can greatly reduce the inefficiency of soil pollution clean-up, which may be caused by loss and self-toxicity when using existing treatments, provide an opportunity to greatly broaden the technology selection of soil pollution purification companies. Its main purpose is to establish a clean and reliable purification business.

The present invention relates to a "purifier of soil oil pollution using tourmaline ionized water". The main purification techniques that can be applied to the present invention are the soil cleaning method which is an in-situ treatment technique and the soil cleaning method which is an ex-situ treatment technique. The design of the present invention is to replace the high surfactants of chemical components that have been used in the soil cleaning method and the soil cleaning method with ionized water to increase the applicability of the technology and to reduce the treatment cost to increase the efficiency of the purification business.

Off-site treatment technologies include Landfarming, Composting, Biopile, Soil Washing, and Thermal Desorption. On-site treatment technologies include Soil Vapor Extraction. ), Biological Ventilation, Bioslurping, In-Situ Bioremediation, Soil Flushing, Air Sparging, Multi-phase Extraction, etc. The main criteria for this classification are determined by the external excavation and movement of the contaminated soil and the nature of the soil, the geographic characteristics of the site, and the soil characteristics.

However, despite the technological diversity, the basic principles applied to purification are based on biological, physical and chemical principles, and the application of these principles is integrated and operated, although there are some differences depending on the site characteristics. to be.

The common purpose of these clean-up techniques is to quickly remove and treat the main contaminants in the site, in order to prevent outside spreading of contaminants around the point where the spill occurred and to increase the purification efficiency.

These pollutants remain in unsaturated soil layers or exist in the form of non-aqueous phase liquids (NAPLs) in the form of free products.The technique of treating NAPLs among the main sources of pollution is LNAPL (Light) Bioslurpng, Multi-Phase Extraction, based on Non Aqueous Phase Liquid and DNAPL (Dense Non Aqueous Phase Liquid) deposited at the bottom of groundwater Phase Extraction can be used, but the treatment of oil pollution present in the Unsaturated Zone is more complex and difficult.

Methods for contaminating unsaturated zone oils include biological ventilation, soil vapor extraction, thermal desorption, and soil flushing. Biological treatment technology focused on aerobic decomposition by microorganisms, Soil Vapor Extraction and Thermal Desorption technology is a physical / thermal treatment method that vaporizes or vaporizes pollutants to be discharged to the outside. Soil Flushing is a combination of chemical and physical methods in which a treatment agent is added to increase the fluidity of contaminants remaining in the unsaturated zone and move it to the lower saturated bed or the desired location to pump it out.

In reality, however, there are various limitations that make it difficult to apply the technology. Bioventing has sufficient disadvantages in the case of high and uniform air permeability in the soil layer, while most soil conditions are irregular and have a disadvantage in that the purification effect is long and the duration is long. Soil Vapor Extraction has the disadvantage of being effective only in highly volatile materials such as gasoline and organic solvents. Soil Flushing, on the other hand, is one of the major soil restoration technologies widely used at home and abroad in connection with various pumping-based technologies.

Soil cleaning method injects the treatment agent through the injection well installed considering the extent and depth of site contamination. The injected treatment agent moves to the surrounding contaminated soil layer through the hole of the injection well and directly oxidizes or emulsifies the contaminants and expands the range of its operation. The pollutants treated in this way are gradually moved to a certain area within the site according to the characteristics of the soil distribution or the flow of groundwater. The extraction wells are installed at the corresponding points to pump the injected treatment agent and the treated pollutant mixture and finally process them on the ground.

Hydrogen peroxide, various surfactants or ozone water are used for this purpose. Hydrogen peroxide and ozone water have the disadvantage that natural biological pollution purification effects cannot be expected due to the side effects of destroying the microbial ecosystem in the soil ecosystem. For this reason, surfactants that directly or indirectly promote biological degradation effects are used. Surfactants enable direct treatment by converting contaminants in unsaturated strata into emulsions that can be extracted / removed and stimulate natural biodegradation of residual materials that are difficult to desorb. Has the advantage of being able to

However, surfactants have a decisive disadvantage in that the treatment cost increases as the contamination range is wider, which can not effectively prevent the outflow to the periphery when the treatment agent is injected to maintain an effective contact area for the soil contamination range. This is unavoidable because the loss is further increased due to the channel phenomena around the injection well, which is present in the treatment of contaminated soil. For this reason, the demand for treatment is unnecessarily increased. Considering that most of the surfactants used in Korea are expensive foreign imported products, the purification cost is increased and the efficiency of purification is difficult due to the difficulty of effective site management. It can only lead to the fall.

For this reason, most domestic companies are fully aware of the necessity of the soil cleaning method using surfactants, but are experiencing difficulties in the field application, which causes a decrease in the choice of soil purification technology, and further makes the soil purification work difficult. Leads to results.

The present invention devised to solve this problem is to operate the soil oil pollutant purifier using tourmaline ionized water, which can continuously produce ionized water having the same effect as the surfactant for a certain period of time by operating a single facility, in conjunction with the soil cleaning system. It has the advantage that it can be an alternative to solve the difficulty of efficient on-site management of the company due to the necessity and cost burden of surfactant purchase. In addition, the present invention can be used more efficiently for cleaning agents during soil cleaning operations based on similar principles.

Tourmaline, filled with the present invention, is the only mineral on earth with permanent electrical properties. Tourmaline is a borosilicate with hexagonal columnar crystals and is a natural mineral belonging to the hexagonal system. Tourmaline has a nickname of tourmaline because the tourmaline crystal itself generates electricity.

Tourmaline ore or powder instantly discharges when it comes in contact with moisture. At this time, the water is electrolyzed and the water molecules (H ₂ O) are separated into hydrogen ions (H +) and hydroxyl ions (OH −).

[Formula 1] H ₂ O → H + + OH-

The separated hydrogen ions (H +) combine with undecomposed water to form hydride ions.

[Formula 2] H + + H ₂ O → H ₃ O + (Hydronium Ion)

That is, alkali ionization of water proceeds, and hydroxyl ions (OH-) combine with surrounding water molecules to form a surfactant (H ₃ O ₂ , Hydroxyl) anion.

[Formula 3] OH- + H ₂ O → H ₃ O _2- (Hydroxyl Ion)

Hydroxyl ions, i.e., sole ions that have been depleted by the tourmaline, become unstable because they exist contrary to this law. As a result, the hydroxyl ions rapidly move to the interface and arrange H-O-H groups toward the inside of the water and H of the O-H groups toward the outside of the water. As the hydroxyl ions are stabilized in this manner, they act as surfactants.

Through this process, it is possible to generate ionized water for treating contaminants such as oil pollution without using a separate surfactant or heated steam.

Therefore, the technical problem to be achieved by the present invention is to provide a useful alternative that can greatly reduce the treatment cost caused by the loss of the treatment agent that can occur in the treatment of most contaminated soil in the field as described above, the soil is the main technology that the treatment agent is used Its main purpose is to establish a credible clean-up business by providing an opportunity to broaden the choice of purifier technology for various treatment techniques including cleaning and soil washing.

When the validity of tourmaline has elapsed or for other reasons it is necessary to remove tourmaline from the present invention, tourmaline is discharged through the "tourmaline outlet 7,8". Water required for the production of the ionized water is supplied internally through the "water supply pipe 9". The core part of the present invention is the "stirrer 10" and the "stirrer impeller 11" connected thereto, and serves to generate ionized water having interfacial activity by causing friction between water and tourmaline. The air pressure generated due to the high speed rotation of the stirrer impeller is measured using the "pressure gauge 12", and is discharged to the outside through the "pressure / gas outlet 13" when the safe operation limit value is exceeded.

Next, let's take a look at the "Ionized Water Discharge and Storage". The generated ionized water is introduced into the product input pipe and the treatment well (injection well) of the contaminant purifier through the "ion water main outlet 14" and "ion water auxiliary outlet 15". The secondary water outlet is intended for preliminary discharge, but it is used together with the primary ionized water outlet when the emissions need to be increased according to the purification site conditions. The water level inside the present invention is measured by the "level sensor 18", which automatically controls the operation of the stirrer impeller by using the lowest and highest water level measured through this. In addition, the water level of the ionized water inside the present invention can also be checked with the naked eye through the "ion water level check site 19". The flow rate of the discharged ionized water is measured by the "flow meter 16", and the water temperature is measured by the "temperature sensor 17", and the measured values through the "electric panel" together with the measured value of the "level sensor 19".
