Among the treatment methods of contaminated water, the oxidation method is a method of treating contaminants by injecting a strong oxidizing substance such as chlorine into contaminated water. However, the use of chlorine has a problem of THM (Total Trihalomethane), and the alternative is ozone. First, the oxidative power is superior to that of chlorine, has a decomposition ability to THM, and has an effect of increasing dissolved oxygen. However, since ozone has a strong oxidizing power but selectively reacts with organic matter, organic matter that can not be treated remains, and depending on the wastewater state, the pollutant can not be completely decomposed into carbon dioxide, and a byproduct such as aldehyde or bromate .

According to an embodiment of the present invention, there is provided an apparatus for treating contaminated water by using an advanced oxidation treatment technique, And analyzes the result of the treatment to derive an optimum combination for the contaminated water, and uses the obtained result in the subsequent treatment of the contaminated water. By applying the optimal combination to the derivation of the optimum combination and the subsequent contaminated water, a technique for efficiently and economically treating the contaminated water is presented.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing an apparatus for treating highly contaminated water according to an embodiment of the present invention. FIG. 1, the apparatus for treating highly contaminated water according to the present invention includes a reaction tank 100, an inflow unit 200, a first sensor unit 210, an outflow unit 300, a second sensor unit 310 The first valve 410, the ozone gas injection unit 500, the second valve 510, the UV reaction unit 600, the ultraviolet ray control unit 610, the control unit 700, And an analysis unit 800.

The reaction tank 100 is a place where the highly oxidative treatment reaction according to the present invention is performed, and the contaminated water flows into the reaction tank 100 and the reaction proceeds by ozone, hydrogen peroxide, ultraviolet rays or the like. The inflow section 200 includes an inflow storage tank IT and a transfer line. The IN shown in Fig. 1 indicates that the contaminated water is introduced into the inflow storage tank IT. OUT indicates that contaminated water treated through the reaction tank flows out to the outside.

A transfer line is formed between the inflow storage tank and the reaction tank 100, and the contaminated water moves to the reaction tank 100 via the inflow storage tank.

The contaminated water flowing into the inflow storage tank can be stirred by the stirrer. Agitation of polluted water aids in the reaction of water treatment. That is, in the water purification process for treating polluted water such as polluted river water, lake water, water source water, and sewage water, flushing and treating pollutants, for example, organic materials, It may be helpful to use a stirring tank in which coagulants and disinfectants are introduced for treatment.

The first sensor unit 210 is formed on the transfer line formed between the inflow storage tank and the reaction tank 100 to measure the concentration of the organic pollutants in the polluted water. In addition, the second sensor unit 310 is formed on the outflow line through which the polluted water flows out to the outside through the reaction tank 100, and the concentration of the organic pollutants in the polluted water is once again measured.

The concentration of the organic pollutants measured by the first sensor unit 210 is compared with the concentration of the organic pollutants measured by the second sensor unit 310 when the polluted water is discharged from the reaction tank 100 to the outside, 100, it is possible to confirm how much organic pollutants are removed. That is, the concentration of the organic pollutants measured by the first sensor unit 210 is the concentration before the reaction occurs in the reaction tank 100, and the concentration of the organic pollutants measured by the second sensor unit 310 The reaction proceeds in the reaction tank 100 by this difference and it can be judged that the organic pollutants have been removed.

At this time, a TOC (Total Organic Carbon) sensor may be included as a sensor for measuring the concentration of organic pollutants in the polluted water, that is, a sensor used in the first sensor unit 210 and the second sensor unit 310. As an example of the TOC sensor, a total organic carbon sensor of Mettler toledo TM can be used. Sensors measuring BOD, COD, pH, DO, turbidity, electrical conductivity, salinity, chlorophyll-a, alkalinity, etc. may be substituted for or additionally to the TOC sensor for more detailed water quality measurements.

The reaction tank 100 is provided with a hydrogen peroxide injection unit 400 for injecting hydrogen peroxide, an ozone injection unit for injecting ozone, and an ozone injection unit for injecting ozone into the reaction tank 100, And a UV reaction unit 600 formed of an ultraviolet lamp for irradiating ultraviolet rays.

The hydrogen peroxide injection unit 400 is coupled to the reaction tank 100 to inject hydrogen peroxide into the reaction tank 100. At this time, an injection line may be formed between the hydrogen peroxide injection unit 400 and the reaction tank 100. The hydrogen peroxide injection unit 400 can inject the hydrogen peroxide into the reaction tank 100 through the injection line. The injection line at this time may be coupled to a transfer line for introducing the contaminated water into the reaction tank 100. At this time, the hydrogen peroxide passing through the injection line may be transferred to the reaction tank 100 while being mixed with the contaminated water passing through the transfer line through the mixing mixer M.

The ozone gas injection unit 500 is connected to the reaction tank 100 to inject ozone gas into the reaction tank 100. At this time, the ozone gas injection unit 500 may include a microbubble diffuser 520. That is, by providing minute bubbles of ozone into the reaction tank 100, it is possible to maximize the contact area between ozone and contaminated water, thereby increasing the oxidation efficiency of the polluted water. As the efficiency of oxidation of polluted water is increased, the removal efficiency of organic pollutants present in polluted water increases.

The UV reaction unit 600 is installed inside the reaction tank 100 and emits ultraviolet rays toward the contaminated water. At this time, the UV reaction unit 600 may be constituted by an ultraviolet lamp which emits ultraviolet rays. The ultraviolet lamp may be provided in a single number or a plurality of ultraviolet lamps may be installed. This can be variously adopted depending on the size of the reaction tank 100 or the amount of polluted water to be treated. Also, the amount of ultraviolet light irradiated in the UV reaction part can be adjusted. That is, the irradiation amount of the UV ultraviolet lamp may be adjusted or the irradiation time may be adjusted.

The apparatus for treating highly contaminated water according to the present invention including the above-described features can treat the contaminated water by various combinations of hydrogen peroxide, ozone, and ultraviolet rays in the reaction tank 100 containing the polluted water. It is possible to obtain a combination that provides the optimal removal efficiency of the organic pollutants in the polluted water to be treated by analyzing the treatment result of the polluted water according to various mutual combinations.

The optimum organic contaminant removal efficiency of the polluted water to be treated is determined by the concentration of the organic pollutants measured by the first sensor unit 210 formed in the inlet 200 according to various combinations of hydrogen peroxide, ozone, And the concentration of the organic pollutants measured by the second sensor unit 310 formed in the outflow unit 300 can be derived.

Further, the present invention can proceed by changing the amount of hydrogen peroxide and ozone injected and the dose of ultraviolet rays. That is, in addition to a method of combining ozone, hydrogen peroxide, and ultraviolet rays, the reaction is repeatedly carried out while changing the amount of injection. It is possible to derive the optimum reaction tank (100) by measuring and comparing the amount of organic pollutants in the treated polluted water at the end of the reaction depending on each combination and each injection amount or the irradiation amount. Further, since the operation can be performed on the pilot scale, the process can be continued to the contaminated water.

In the present invention, the first valve 410 is connected to the hydrogen peroxide injection unit 400, the second valve 510 is connected to the ozone gas injection unit 500, the ultraviolet ray control unit 610 is connected to the UV reaction unit 600, . That is, the first valve 410 is connected to the hydrogen peroxide injection unit 400 to regulate the amount of hydrogen peroxide injected into the reaction tank 100, and the second valve 510 is connected to the ozone gas injection unit 500, The ultraviolet ray control unit 610 controls the amount of ultraviolet rays irradiated to the contaminated water.

At this time, the opening / closing amount of the first valve 410, the second valve 510, or the ultraviolet ray irradiation amount of the ultraviolet ray adjusting part 610 is controlled by the controller 700. That is, the control unit 700 is connected to the first valve 410, the second valve 510, and the ultraviolet ray control unit to control the amount of the ozone gas or the hydrogen peroxide to be injected or the ultraviolet ray irradiation amount, The removal rate is measured.

In addition, the controller 700 controls at least two combinations of the ozone gas injection unit 500, the hydrogen peroxide injection unit 400, and the UV reaction unit 600 to be activated. That is, the control unit 700 may include a combination of the ozone gas injection unit 500 and the hydrogen peroxide injection unit 400, or the combination of the ozone gas injection unit 500 and the UV reaction unit 600 or the hydrogen peroxide injection unit 400 and / The first valve 410, the second valve 510, or the second valve 510 may be operated so that the combination of the UV reaction unit 600 or the combination of the ozone gas injection unit 500, the hydrogen peroxide injection unit 400, And controls the ultraviolet ray control unit 610. By applying various combinations for the high-level oxidation treatment to produce polluted water by generating OH radicals, the influence of the scavenger which interferes with the generation of OH radicals and the number of pollution requiring treatment in various cases Can be derived.

The analysis unit 800 according to the present invention is connected to the outflow unit 300 and the second sensor unit 310 and controls the amount of hydrogen peroxide to be controlled by the control unit 700 according to the amount of the hydrogen peroxide, 2 sensor unit 310 to analyze the change of the concentration of the organic pollutants. That is, not only the concentration of the organic pollutants measured by the second measuring unit according to at least two combinations of the ozone gas injection unit 500, the hydrogen peroxide injection unit 400, and the UV reaction unit 600, The variation of the concentration of the organic pollutants measured by the second measuring unit according to various doses or doses in the case of each combination is analyzed.

Thus, the analysis unit 800 can derive the optimal combination to be applied to the contaminated water and the optimal injection amount or irradiation amount in the combination. The optimal combination and optimal injection amount or dose thus derived can be applied to the subsequent contaminated water treatment.

In detail, the analysis unit 800 is connected to the control unit 700, and transmits the optimum combination derived from the analysis unit 800 and the optimal injection amount or irradiation dose to the control unit 700, and the control unit 700 The optimal combination of delivery, and the optimal amount of injection or irradiation, will treat the remaining contaminated water. Therefore, it is possible to economically and efficiently remove organic pollutants from the remaining polluted water.

In addition, the present invention may further include a cooling unit (C) formed to surround the reaction tank. Due to the progress of the oxidation reaction, the temperature inside the reaction tank may increase and the temperature may rise. Therefore, the cooling section surrounds the reaction tank and supplies cooling water, thereby preventing the temperature rise of the reaction tank and maintaining a constant temperature. That is, when various combinations of reactions proceed, each reaction can proceed within a certain temperature range. In other words, the temperature is controlled.

Hereinafter, as another embodiment of the present invention, a method for treating the contaminated water with a high degree of oxidation will be described. FIG. 2 is a diagram showing a process of deriving an optimal combination for treating a contaminated water, as an example of a method of treating a contaminated water altitude.

The method for treating highly contaminated water according to the present invention comprises the steps of measuring the concentration of organic pollutants in the contaminated water flowing into the reaction tank by water treatment using the advanced oxidation treatment apparatus, A step of combining at least two of the hydrogen peroxide injecting unit, the ozone gas injecting unit, and the UV reaction unit, sequentially advancing the reaction according to each combination for a predetermined time, Measuring the concentration of the organic pollutants in the water, and treating the remaining polluted water according to the combination in which the concentration of the measured organic pollutants in the polluted water flowing out is the minimum.

At this time, the measurement of the concentration of the organic pollutant may proceed to the TOC sensor.

In the present invention, the concentration of the organic pollutants in the contaminated water flowing into the reaction tank is measured using a TOC sensor, the concentration of organic pollutants in the treated water flowing out of the reaction tank is measured using a TOC sensor, The concentration of organic pollutants before and after the reaction can be compared.

At this time, the reaction in the reaction tank may proceed by a combination of hydrogen peroxide and ozone gas, a combination of hydrogen peroxide and ultraviolet rays, or a combination of ozone gas and ultraviolet rays, or a combination of hydrogen peroxide, ozone gas and ultraviolet rays.

Then, by measuring the amount of the organic pollutants in the treated water after the reaction according to each combination, it is possible to derive the optimum combination for the contaminated water treatment.

As in the above-described contaminated water elevation oxidation treatment apparatus, the method of oxidizing the contaminated water according to the present invention may also derive an optimal injection amount or irradiation amount while changing the injection amount of hydrogen peroxide and ultraviolet rays or the irradiation amount of ultraviolet rays.

Accordingly, the optimal combination amount and the optimum injection amount or irradiation amount according to the combination can be derived, and the remaining contaminated water can be treated under the derived reaction conditions, thereby efficiently and economically treating the polluted water.

As an example according to the present invention, the BPA removal efficiency in the polluted water was measured. At this time, a reaction vessel of 20 to 28 L size was used for the experiment, and an ultraviolet lamp was tested using a low pressure lamp (20 mW / cm 2 ). The reaction time of each combination is preferably within 5 minutes. This is because, even if each combination was allowed to react for 5 minutes or longer, there was no significant difference from the reaction conducted for 5 minutes, and the removal rate of organic pollutants tended to decrease.

In addition, ozone was injected in the range of 0-10 mg / L, and the experiment was conducted. Even if ozone was injected more than 10 mg / L, the removal rate of organic pollutants did not change greatly, but the removal rate of organic pollutants tended to decrease.

In addition, the hydrogen peroxide was regulated stepwise in the dose range from 0 to 300 mg / L. Even if ozone was injected more than 300 mg / L, the removal rate of organic pollutants did not change much, but the removal rate of organic pollutants tended to decrease.

Therefore, it is possible to determine the injection amount or the irradiation amount according to the optimal combination and optimal combination while advancing the reaction according to each combination within the threshold range of the reaction time and the injection amount of ozone and hydrogen peroxide which are derived empirically.

The scope of protection of the present invention is not limited to the description and the expression of the embodiments explicitly described in the foregoing. It is again to be understood that the scope of protection of the present invention can not be limited by obvious alterations or permutations of the present invention.
