Description

High pressure injection washing system for contaminated soil using a pumping out well, and the method therefor}

The present invention relates to a high pressure cleaning system for polluted soil and a driving method thereof.

A rotary perforator for spraying the decontamination chemical and the water of the tank into the soil contaminated with high pressure, a drain well and a drain well pump for collecting the treated water, and a control unit for controlling the high pressure pump and the drain well pump of the rotary perforator,

The control unit determines whether there is an abnormality of the drainage pump and controls the high pressure pump and the drainage pump in accordance with the result, thereby preventing secondary pollution from spreading the pollutants along the ground surface and effectively recovering the treated water discharged with the pollutants. The present invention relates to a high pressure cleaning system for polluted soil and a driving method thereof.

Soil pollution has the absolute function of the survival base of living things such as animals and plants as well as water quality and air, and is an important component of the environment. The difference between soil and air and water is that there is little fluidity. Contaminants introduced into the soil are immobile unless they have fluidity on their own, except by soil water or soil air present in the soil voids. So soil pollution is slower than water quality or air pollution, and the pollution is confirmed only after a long time due to the characteristics that are difficult to recognize directly.

Unlike soils and air, soils are usually complex in composition and diverse in structure, making it difficult to grasp the changes in the distribution and form of pollutants introduced into the soil. By continually. Accordingly, the purification technology on the contaminated site has been developed in various forms and applied to the site. The classification of the cleaning method is divided into soil treatment technology, groundwater treatment technology or unsaturated zone treatment technology and saturated zone ( Saturated zone treatment technology.

These technologies are divided into In-Situ technology and Ex-Situ technology, which are treated at the contaminated site again. These classifications include excavation (for soil) or pumping (for groundwater) processes of contaminated media. It depends on whether it is included. In other words, underground treatment technology is a technology that directly inserts a well into the ground without digging or pumping contaminated soil and groundwater, and directly treats the soil and groundwater to an appropriate treatment facility after excavating and pumping contaminated soil and groundwater. Refers to the technology of processing.

The soil washing technology of the present invention is based on a technique for purifying and extracting contaminants in a contaminated soil and separating the contaminated fine soil with a representative Ex-situ method. The method is a technique for separating the harmful organic pollutants and heavy metals from soil particles by reducing the surface tension of harmful organic pollutants bound to the soil particles using an appropriate cleaning agent or by changing the heavy metal into a liquid phase. In this process, most of the contaminants are enriched through strong bonding with the clay (clay or silt) rather than granulated soil (sand or gravel), and the fine particles are separated from the particulate because they are adsorbed or aggregated in the granulated soil. And processing is important.

In such a soil washing process, non-contamination of a predetermined size or more is removed and homogenized, and the chemicals such as extractant, cleaning solution, acid or chelating agent are used together with water to increase the cleaning efficiency of contaminants. Fine soils concentrated in these contaminants are separated by sieve separation or gravity sedimentation, and generally require additional treatment in the form of sludge, and coarse earth may be reused as cover soil as restored soil. At this time, the treatment method of the washing waste liquid generated is applied to ion exchange, solvent extraction, flocculation precipitation, and the like.

As a background art related to the decontamination by cleaning the contaminated soil of the present invention, there is a technique for restoring the soil contaminated with heavy metal using the organic waste of the Republic of Korea Patent Publication No. 10-0909082 shown in FIG. This technology installs an injection tube formed with an injection hole in the drilling hole after drilling the ground, and supplies the fermentation broth to the soil through the injection hole by supplying the fermentation broth at high pressure through the injection tube, and the fermentation broth by rotating the injection tube at a predetermined speed. Characterized in that the input.

However, this technology consists only of supplying fermentation broth to activate microorganisms and restoring the soil through the adsorption and oxidation of microorganisms, which leads to the spread of contaminated areas and secondary pollution due to the diffusion of fermentation broth. have.

This technology relates to a contaminated soil improvement device that adsorbs harmful substances by replacing them with slurry carbonized adsorbents to purify soil and water quality, and drills holes in the ground from the surface to the contaminated soil. Insert the injection nozzle which installs the injection nozzle which injects the bamboo charcoal powder of air and slurry state into the ground, pulls it up while rotating the injection tube, injects water and air from the injection nozzle, and agitates the soil, It discharges the contaminated soil which has become a state to the ground from between the hole and the injection pipe, and injects the slurry of bamboo charcoal powder in the slurry state from the injection nozzle installed below, and embeds the slurry carbonized adsorbent in the space of the discharged soil. It is characterized by.

However, this technique places a contaminant on the contaminant by embedding a carbon adsorbent that adsorbs the contaminant.

As another background technology related to the decontamination by cleaning the contaminated soil of the present invention, there is a soil pollution purification system technology of the Republic of Korea Patent Publication No. 10-0395691 shown in FIG. This technology continuously sprays contaminated soil and collects oil into a well-determined sump, then pumps it as a recovery pump, transfers it to the flow control tank, separates the oil from the oil-water separation tank, and sequentially processes the chemical treatment tank. In addition, through the ozone oxidizer, physical, chemical, and biological treatments are performed, as well as purified water, which is characterized in that the spraying process is recycled.

This technology, however, requires continuous application of water to contaminated soil, and has a number of collection wells with a certain depth and spacing, which not only increases the cost but also provides a recovery pump which is provided to transport the wastewater along the delivery line. Since each collection well is provided in the collection pump, waste water may diffuse into the soil when a failure or abnormality of the recovery pump occurs, causing secondary pollution.

As another background technology related to decontamination by cleaning of contaminated soil of the present invention, liquid contaminant removal of soil and groundwater using a mixture of alcohols and air of Korean Patent Publication No. 10-0451976 shown in FIG. There is technology. This technology injects alcohol and air into the contaminated groundwater layer at the same time, and dissolves and removes liquid contaminants as alcohol, and air uses a mixture of alcohol and air to volatilize and remove liquid contaminants present in groundwater and unsaturated soil layers. And an apparatus for removing liquid contaminants in groundwater and a method for removing contaminants using the same, comprising: unsaturated soil layer contaminated by liquid contaminants, and a supply pipe and a mixture of alcohols and air in the groundwater layer, Installing a liquid phase discharge pipe and a gaseous discharge pipe to collect the air to discharge to the outside, respectively, the ratio of air and alcohol in the supply pipe is 2: 1 to 6: 1 ratio and 60% by volume after alcohol is injected into the ground water Mixed gas injection step of injecting to maintain the above alcohol concentration, the gas at the same time as the mixed flow injection step It is characterized by consisting of a discharge step of discharging the alcohol and air ejected through the supply pipe by providing a vacuum force to the phase discharge pipe and the liquid phase discharge pipe.

However, this technology is designed to discharge the air layer volatilizing liquid pollutants through the gas phase discharge pipe, and the air layer containing the discharged pollutants is discharged to the atmosphere after being treated by the ground treatment apparatus. Removal is virtually impossible, and there are constraints that alcohols remain in the soil during or after the restoration process.

At this time, the rod driving unit 140 controls the rising speed and rotation of the direct hole rod 160, and drives the straight hole rod 160 up and down to maintain the set rising speed and rotation speed.

In the operation of the high pressure cleaning system of the contaminated soil with the drainage well of the present invention, when the investigation on the contaminated area is completed, the rotary boring machine 100 is moved to inject the direct drilling rod 160 into the ground, and the chemical tank 130 The rod driving unit 140 of the control unit to control the ascending speed and rotation of the direct hole rod 160, and the high pressure of the water of the decontamination chemical and the water tank 120 through the spraying unit 180 at the end of the rod water supply unit 150 To live with. Accordingly, when the decontamination chemicals such as cleaning agents, soil contaminants, hydrogen peroxide, etc. are injected through ultra high pressure through the direct hole rod 160, the gap between the soil particles and the soil particles is formed in the form of a knife in the ground. When the decontamination chemical penetrates into the gap at high pressure, oil contaminants and heavy metal contaminants attached to the surface of the soil particles are desorbed, oxidized and decomposed, and the contaminants are ejected to the surface by jets of high pressure water.

At this time, the treated water containing the decontamination chemical is ejected to the surface along with the contaminant, and when the effective recovery or treatment of the treated water is not carried out, contaminants may spread along the surface to cause secondary pollution. . In order to effectively recover the treated water, total control must be performed, including a high pressure pump 110 for supplying the decontamination drug and water to the lower end of the region in which the contaminant 170 is located in the rotary puncher 100.

The drainage well 600 is disposed within a predetermined distance from the rotary puncher 100, and is installed to collect the treated water at the bottom from the ground on which the rotary puncher 100 is located. In addition, the treatment water recovery unit 700 includes a configuration that is purified through a purification facility located in another place by transferring a separate purification facility or treated water to process the treated water in the field.

The high pressure cleaning system of the contaminated soil with the drainage well of the present invention is equipped with a direct hole rod 160 connected with the high pressure pump 110, and at the end of the soil contaminated by the high pressure of the decontamination chemical and the water of the water tank 120. It is provided with a spraying unit 180 for spraying on the ground, to excavate the ground to perform a cleaning action at the bottom of the area where the contaminant 170 is located, and to collect the treated water generated through the cleaning action The drainage well 600 and the treated water recovery part 700 which collect | recovers the process water from the said drainage well 600 are made into a basic structure. The drainage well 600 is excreted within a certain distance from the rotary puncher 100, it is hypothesized to form a ring around the point where the rotary puncher 100 is located to collect the treated water at the bottom from the ground where the rotary puncher 100 is located. do. In addition, the treatment water recovery unit 700 includes a configuration that is purified through a purification facility located in another place by transferring a separate purification facility or treated water to process the treated water in the field. The drainage well 600 may be disposed in any shape over the periphery of the rotary puncher 100 within a predetermined distance from the rotary puncher 100.

Figure 9 shows the overall configuration of a high pressure cleaning system for contaminated soil with a drain well of the present invention. The high pressure cleaning system of the contaminated soil with the drainage well of the present invention is equipped with a direct hole rod 160 connected with the high pressure pump 110, and at the end of the soil contaminated by the high pressure of the decontamination chemical and the water of the water tank 120. Rotary perforator 100 having a spraying unit 180 sprayed on the water, a sump 600 for collecting the treated water generated through the cleaning action, and a treated water recovery unit for recovering the treated water from the sump 600 It is provided with a 700, the drain well 600 is provided with a drain well pump 200 for pumping the treated water to the outside, and controls the high-pressure pump 110 and the drain well pump 200 of the rotary perforator 100 The control unit 700 is provided. In the drawing, the sump pump 200 is illustrated as an underwater pump located in the sump 600, but the sump pump 200 of the present invention may be provided outside the sump well.

The controller 700 determines whether there is an abnormality of the drainage pump 200 in order to effectively recover and process the treated water jetted together with the contaminants to prevent secondary pollution from spreading the contaminants along the ground surface. Accordingly, the high pressure pump 110 and the drainage pump 200 are interlocked with each other.

10 shows an example of the configuration of the sump pump 200 in the high pressure cleaning system of the contaminated soil with the sump. The sump pump 200 for pumping the treated water jetted together with the contaminants by the rotary puncher 100 from the sump 600 is targeted for sewage and wastewater including sludge. Therefore, when overload is applied due to sludge, soil, gravel, etc., damage to the drain pump motor 200a for driving them may occur.

In addition, the drain pump motor 200a mostly uses an induction motor using a commercial AC power source, and rotates in reverse to destroy the pump when the load amount given to the rotor and the induction phase are shifted when the motor is started. It also happens. Therefore, in the use of the drain pump 200, the state of the pump is efficiently monitored by using the rotation direction and the rotation speed of the drain pump pump 200a, and when an abnormal condition occurs, the high pressure pump 110 and the drain pump of the rotary borer 100 are generated. There is a need for means to interoperate with (200).

The drainage pump 200 control system of the present invention shown in FIG. 10 further includes a detector unit 270, which detects the shaft on the motor shaft 240 of the drainage pump motor 200a. And a marker A 250 and a marker B 260 attached to each other at a distance spaced in the direction, and configured to include an LED 230 for irradiating reading light to the marker A 250 and the marker B 260. . In addition, in order to sense the light reflected from the marker A 250 and the marker B 260, the photo detector A 210 and the photo detector B 220 facing each marker are disposed and the photo detector A 210 is disposed. And a control unit 700 for reading the signal from the photodetector B 220 and driving the LED 230. In the embodiment of the present invention, the detector unit 270 is described as being provided in the motor shaft 240 between the drain pump pump 200a and the gearbox 280, but the detector unit 270 is the drain pump The other end of the motor 200a may be provided on the motor shaft 240.

11 shows the working relationship of the detector unit 270 of the present invention. Marker A 250 and Marker B 260 attached at a distance in the axial direction on the motor shaft 240 of the pump motor 200 are half of the one rotation angle 2π of the motor shaft 240 The black parts, which can be detected as different phases at angles within π, are provided at different phase positions. The marker of FIG. 11 shows an embodiment in which marker A 250 is provided in phase prior to marker B 260 at an angle within π. The marker A 250 and the marker B 260 as described above, when the motor shaft 240 is rotated in the clockwise direction, the black portion of the marker A 250 is first detected by a low pulse of the detection output 250a. Subsequently, a low pulse of the sensing output B 260b is sensed from the marker B 260. In addition, when the motor shaft 240 rotates counterclockwise, the low pulse of the black portion of the marker B 260 is first detected by the sensing output B 260b, and then the black portion of the marker A 250 is detected. It is detected by the low pulse of the output 250a. In addition, it is also possible to calculate the number of revolutions per minute (rpm) by measuring the interval between the sensing pulses of only the marker A 250 or the marker B 260.

12 is a diagram illustrating an embodiment of calculating a rotation direction and a rotation speed of a drain pump pump 200a for pumping treated water from a drain well 600 in a high pressure cleaning system of a contaminated soil having a drain well of the present invention. When the interval time between the pulses of the sensing output A 250a is t1 and the interval time between the low pulses of the sensing output A 250a and the sensing output B 250b is t2, the sensing output B is at an angle within the rotation angle π. When a low pulse of 250b is detected, t2 has a value within half of t1. In this case, it may be determined that the drain pump motor 200a rotates clockwise (or forward). When the low pulse of the detection output B (250b) is detected at an angle within the rotation angle π, when t2 is greater than half of t1, it is determined that the drain pump motor 200a rotates counterclockwise (or reverse direction). can do. In addition, the rotation speed of the sump pump motor 200a may be calculated using a period of t1. When the t1 and t2 is measured, the counter is used. At this time, the counter has a limited number of bits, so when the drain pump motor 200a rotates at a low speed at the start, when it is stuck due to an overload, the counter rotates to a normal state. In the case of excessive sluggishness due to heavy sludge or the like, the counter value is recognized only as the maximum value or counted again from the initial value, which may cause errors in the rotation direction and the rotation speed value. The high pressure cleaning system and method thereof for contaminated soil having a drainage well according to the present invention overcome the above error and stop the high pressure pump 110 and the drainage well 200 of the rotary perforator 100 when the abnormal state occurs. A high pressure cleaning system and method of a contaminated soil having a drainage well for preventing the secondary contamination of the treated water ejected with the pollutant along the surface of the pollutant are characterized.

13 shows a control unit configuration of the present invention. The controller 700 of the present invention includes a controller 710; And a marker A 250 and a marker B 260 attached to the motor shaft 240 of the drain pump pump 200a of the drain pump pump 200 at an axially spaced distance.

The alarm 740 is configured to generate an alarm that is divided according to a control signal from the controller 710.

The controller 710 calculates the rotation direction and the number of rotations by t1 and t2 counted by the CTC 760. When the t1 and t2 values are repeatedly read to the final values, the controller 710 passes through the pump motor driver 750. Stop the sump pump motor 200a, stop the high pressure pump 110 and the sump pump motor 200a of the rotary drilling machine 100 through a programmable input / output (PIO) 780 to operate the alarm 740 It is configured to.
