Description

Apparatus for removing dissolved organic matter using Ultra High Frequency}

The present invention relates to a technique for removing soluble organics using microwaves, and more particularly, to an apparatus for removing soluble organics using microwaves capable of removing soluble organics through chemical reactions and microwave contact reactions and post reactions by a pretreatment reaction. .

In general, most of the technologies for removing the dissolved organic matter constitute a reactor in the chamber to transfer energy to the reactor using microwave reflected waves generated from the magnetron.

Such a reactor has a large spatial range to be delivered to the reactor because energy is transferred to the reactor through reflection, but the strength of the energy is relatively low.

In addition, the conventional method of oxidizing the chemicals using Fenton is to remove organic contaminants by generating OH radicals to generate additional sludge due to iron deposits to the chemical and sludge treatment costs used to treat the contaminants. There is a disadvantage in that a cost is required and a site requirement for the size of the reactor for the drug reaction is required.

Therefore, in order to improve such a problem, there is a need for a technology capable of shortening a reaction time of a drug and increasing an oxidizing power.

The microwave reactor 40 provides microwaves to the oxidant mixed organic material in which the oxidant is mixed so that oxidation reaction in the organic material is accelerated to decompose the hardly decomposable organic material.

To this end, the microwave reactor 40 is a waveguide 42 formed in a certain length to transmit microwaves, a magnetron (or microwave generator) 44, waveguide 42, which is installed on one side of the waveguide 42 to generate microwaves Is installed on the other side of the magnetron 44 to generate microwaves in the reaction tube 46 and the magnetron 44 where the oxidation reaction occurs in the oxidant mixed organic material supplied therein by the microwaves transmitted through the waveguide 42. And a power supply unit 48 for supplying power.

The microwave reactor 40 is such that the microwave energy generated by the magnetron 44 passes through the waveguide 42 having a certain length, and thus the energy of the microwave is increased so that the energy transfer force can be increased compared to the microwave reactor made of the chamber type. do.

On the other hand, the cooling means (not shown) for removing the heat generated by the high electromagnetic field density when the microwaves oscillated in the magnetron 44 is transmitted to the reaction tube 46 through the waveguide 42, the magnetron 44 And a waveguide 42 between the reaction tube 46.

The reactor 50 stores the organic material oxidized and reacted through the microwave reactor 40. That is, the decomposition product in which the organic substance which is a hardly decomposable organic substance decomposed by the oxidation reaction by microwaves is stored in the reaction tank 50.

Such, the reaction tank 50 may be formed integrally with the reaction tube 46 of the microwave reactor 40 or may be separated separately.

The sensor unit measures the pH value, ORP (Oxidation Reduction Potential) value and temperature of the organic material supplied to the microwave reactor 40 and the pH value, ORP value and temperature of the decomposition product stored in the reactor 50.

To this end, the sensor unit is installed in the supply line 30 for supplying the organic material and the oxidant to the microwave reactor 40, the first pH sensor 81, the first ORP sensor to measure the pH value, ORP value and temperature of the organic material, respectively A second pH sensor 84 installed in the first sensor unit and the reaction tank 50 including the 82 and the first temperature sensor 83 to measure the pH value, the ORP value, and the temperature of the decomposition product in the reaction tank 50, respectively; And a second sensor part including a second ORP sensor 85 and a second temperature sensor 86.

pH adjuster storage tank 60 is a pH adjuster (for example, to adjust the pH value of the decomposition product so that the pH value of the decomposition products stored in the reaction tank 50 is maintained in the reference range pH value (for example, pH 6.5 ~ 8)) , NaOH).

In this case, the reason why only the alkaline agent such as NaOH is used as the pH adjusting agent is that the pH value of the decomposition product is lowered during the oxidation reaction by the oxidizing agent, so that the pH value of the decomposition product can be adjusted even when using only an alkali agent such as NaOH.

The controller 70 controls the amount of the organic material and the oxidant supplied to the microwave reactor 40 through the supply line 30 according to the pH value, the ORP value, and the temperature supplied from the sensor unit, and to the reactor 50. The amount of pH regulator supplied is controlled, and the operation of the microwave reactor 40 is controlled.

Dissolved organic matter removing apparatus using the microwave of the present invention having such a configuration is supplied by the inlet pump 12, the inlet pump 12 for supplying the organic material stored in the organic storage tank 10 to the supply line (30) The first flow meter 14 for measuring the supply amount of the organic material supplied to the line 30, the chemical pump 22 for supplying the oxidant stored in the oxidant storage tank 20 to the supply line 30, the chemical pump 22 Second flow meter 24 for measuring the amount of oxidant supplied to the supply line by the pH, pH regulator pump 62 for supplying the pH regulator stored in the pH regulator storage tank 60 to the reaction tank 50, pH regulator pump ( And a third flow meter 64 for measuring the pH regulator feed amount supplied to the reactor 50 by 62).

Hereinafter, an operation method of the dissolved organic substance removing apparatus using the microwave of the present invention having the above configuration will be described.

First, when organic matter stored in the organic matter storage tank 10 is supplied to the supply line 30 by the operation of the inflow pump 12, the first flow meter 14 installed in the supply line 30 is connected to the supply line 30. The amount of organic matter supplied is measured and transmitted to the controller 70.

When the organic material is supplied to the supply line 30 as described above, the oxidant stored in the oxidant storage tank 20 is supplied to the supply line 30 by the operation of the chemical pump 22, and the oxidant supply amount supplied to the supply line 30. It is measured by this second flowmeter 24 and transmitted to the control unit 70.

Meanwhile, the organic material and the oxidant are supplied to the microwave reactor 40 while being mixed with each other in the supply line 30, and a mixing tank for mixing the organic material and the oxidant may be separately installed between the supply line 30 and the microwave reactor 40. have.

When the oxidant mixed organic material mixed with the organic material and the oxidant is supplied to the microwave reactor 40 through the supply line 30, the first pH sensor 81, the first ORP sensor 82, and the first ORP sensor 82 are installed in the supply line 30. The pH value, the ORP value, and the temperature of the oxidant mixed organic material are measured by the one temperature sensor 83 and transmitted to the controller 70.

Accordingly, the controller 70 controls the operation of the chemical pump 22 so that the oxidant is not supplied to the supply line 30 when the pH value transmitted from the first pH sensor 81 is less than the reference range (ie, the chemical pump). (22) operation stop), and if the pH value transmitted from the first pH sensor 81 exceeds the reference range, the operation of the chemical pump 22 is controlled to increase the amount of oxidant supplied to the supply line 30, If the pH value transmitted from the first pH sensor 81 is within the reference range, the operation of the chemical pump 22 is controlled to maintain the current state.

At this time, the controller 70 operates the chemical pump 22 so that the operating speed of the chemical pump 22 is increased by Equation 1 below when the pH value transmitted from the first pH sensor 81 exceeds the reference range. To control.

[Equation 1]

Chemical pump operation speed = (oxidant supply amount × oxidant concentration) / (organic supply amount + oxidant supply amount)

On the other hand, when the oxidant mixed organic material is supplied to the microwave reactor 40 through the supply line 30, the microwave reactor 40 generates a microwave so as to trigger the oxidation reaction by the microwave in the reaction tube 46, the reaction tube 46 To pass).

At this time, since the microwave reactor 40 is provided with a waveguide 42 having a predetermined length between the magnetron 44 and the reaction tube 46, the microwaves oscillated from the magnetron 44 are separated from each other in the waveguide 42. Since the light is reflected in the down / left / right direction and is transmitted to the reaction tube 46, the microwave having a large energy is transmitted to the reaction tube 46.

When the microwave with high energy is supplied to the reaction tube 46, the oxidation reaction force can be increased due to the high energy of the microwave, and the decomposition of the hardly decomposable organic material is facilitated by the high oxidizing power.

On the other hand, when the decomposition products decomposed by the oxidation reaction in the reaction tube 46 is stored in the reaction tank 50, the second pH sensor 84, the second ORP sensor 85 and the second temperature sensor installed in the reaction tank 50 86 measures the pH value, the ORP value, and the temperature of the decomposition product and sends it to the control unit 70.

In this case, the controller 70 compares the first ORP value measured by the first ORP sensor 82 and the second ORP value measured by the second ORP sensor 85, and according to the oxidizing power of the reaction tank 50 detected. Control the operation of the pump 22, compares the first temperature value measured by the first temperature sensor 83 and the second temperature value measured by the second temperature sensor 86, according to the detected temperature information power source ( The operation of 48 controls the microwave energy emitted from the magnetron 44.

In other words, when the ORP change value, which is a value obtained by subtracting the first ORP value from the second ORP value, exceeds the reference range, the control unit 70 operates the chemical pump 22 so that the oxidant is not supplied to the supply line 30. When the control (that is, the operation of the chemical pump 22 is stopped) and the ORP change value is less than the reference value range, the operation of the chemical pump 22 so that the amount of oxidant supplied to the supply line 30 is increased by Equation 1 described above. If the ORP change value is within the reference value range, and controls the operation of the chemical pump 22 to maintain the current state.

In addition, the controller 70 controls the operation of the magnetron 44 by comparing the second temperature value transmitted from the second temperature sensor 86 with the first temperature value transmitted from the first temperature sensor 83 (preferably). Controls the operation of the power supply unit 48).

In other words, the controller 70 controls the power supply unit 48 to reduce the energy of the microwave generated by the magnetron 44 when the temperature change value, which is a value obtained by subtracting the first temperature value from the second temperature value, exceeds the reference value range. If the temperature change value is less than the reference value range, the power supply unit 48 is controlled to increase the energy of the microwaves oscillated from the magnetron 44. If the temperature change value is within the reference value range, the power supply unit 48 is maintained. ).

On the other hand, the control unit 70 receives the pH value of the decomposition product stored in the reaction tank 50 from the second pH sensor 84, if the pH value of the decomposition product delivered from the second pH sensor 84 exceeds the reference value, pH The pH adjuster pump 62 is controlled so that the pH adjuster is not supplied from the regulator storage tank 60 to the reactor 50 (that is, the operation of the pH adjuster pump 62 is stopped), and the pH value of the reactor 50 is lower than the reference value. In this case, the speed of the pH regulator pump is controlled as shown in Equation 2 below so that the supply amount of the pH regulator introduced into the reactor 50 is increased, and the current state is maintained when the pH value of the reactor 50 is within the reference range. The operation of the pH adjuster pump 62 is controlled as possible.

[Equation 2]

pH regulator pump operating speed = (pH regulator flow rate × pH regulator concentration) / (organic supply supply + pH regulator supply)

In the above description, the control unit 70 controls only the operations of the chemical pump 22 and the pH regulator pump 62 when the oxidant mixed organic material is supplied to the microwave reactor 40 through the supply line 30. The oxidizing agent 70 is supplied to the microwave reactor 40 through the supply line 30 by controlling the inflow pump 12 to perform the operation opposite to that of the chemical pump 22 when controlling the operation of the chemical pump 22. It is also possible to adjust the feed amount of the mixed organics.

In other words, the controller 70 increases the supply amount of the oxidant supplied to the supply line 30 when the pH value transmitted from the first pH sensor 81 exceeds the reference range, and the chemical pump so that the inflow rate of the organic material is reduced. The operation of the 22 and the inlet pump 12 can be controlled.

As described above, in the dissolved organic material removing apparatus using microwaves according to the embodiment of the present invention, since the waveguide 42 is formed to have a predetermined length, the microwaves oscillated from the magnetron 44 are up / down / left / right in the waveguide 42. Reflected in the right direction to have a high energy, since the microwave of this high energy state is transmitted to the reaction tube 46, due to the accelerated oxidation reaction by the microwave of the high energy state, the reaction time of the drug is increased and the oxidizing power is increased, thereby making it difficult to decompose. Organic matter can be easily decomposed.

In addition, the dissolved organic matter removing apparatus using microwave according to an embodiment of the present invention is to compare the pH value, ORP value and temperature of the organic matter before the oxidation reaction with the oxidizing agent for organic decomposition by comparing the pH value, ORP value and temperature after the oxidation reaction By controlling the dosage of the pH adjuster, it is possible to prevent excessive use of the chemicals, thereby reducing the organic treatment cost.

As described above, in the detailed description of the present invention, a preferred embodiment of the present invention has been described, but this is only illustrative of the best embodiment of the present invention and not intended to limit the present invention. In addition, any person having ordinary skill in the art to which the present invention pertains may have various modifications and imitations without departing from the scope of the technical idea of the present invention.
