Claims

[1] An electrochemical measurement system for decomposing organic compounds in wastewater and analyzing heavy metals in the wastewater, comprising: a lower plate having a channel plate-receiving portion formed in the upper side thereof; a flow channel plate, which is received in and coupled to the channel plate- receiving portion of the lower plate and includes, formed in the upper side thereof, an organic compound-decomposing channel, a heavy metal analysis channel and a discharge channel, and an organic compound decomposition electrode-receiving portion and a heavy metal analysis electrode -receiving portion, which communicate with the organic compound-decomposing channel and the heavy metal analysis channel, respectively; an upper plate, which is coupled to the lower plate and the upper side of the flow channel plate so as to seal the upper side of the channels; an organic compound decomposition electrode and a heavy metal analysis electrode, which are received in and coupled to the organic compound decomposition electrode -receiving portion and the heavy metal analysis electrode- receiving portion, respectively; and a flow changeover portion, comprising an on/off valve, which is provided at the upper side of the upper plate and coupled to one end of each of the organic compound-decomposition channel, the heavy metal analysis channel and the discharge channel so as to selectively open and close the wastewater outlet of each of the organic compound-decomposition channel and the heavy metal analysis channel, and an on/off switch for operating the on/off valve.

[2] The electrochemical measurement system of Claim 1, wherein the lower plate is formed of an aluminum material having an oxide layer formed on the surface thereof.

[3] The electrochemical measurement system of Claim 1, wherein the flow channel plate is formed of elastic synthetic resin.

[4] The electrochemical measurement system of Claim 3, wherein the flow channel plate is formed of PMDS.

[5] The electrochemical measurement system of Claim 1, wherein the wastewater inlet of each of the organic compound-decomposing channel and the heavy metal analysis channel is formed in a circular shape, the wastewater outlet thereof is connected with the on/off valve, and the portion between the wastewater inlet and the wastewater outlet is formed in a curved shape consisting of continuously connected U shapes.

[6] The electrochemical measurement system of Claim 1, wherein the organic compound-decomposing electrode is received in and coupled to the organic compound decomposition-receiving portion, such that it comes in contact with wastewater introduced into the organic compound-decomposing channel, thus decomposing organic compounds in the wastewater.

[7] The electrochemical measurement system of Claim 6, wherein the organic compound-decomposing electrode comprises: a body, which corresponds to the shape of the organic compound decomposition electrode-receiving portion and is coupled hermetically to the organic compound decomposition electrode-receiving portion; a decomposition electrode, which is provided at the lower end of the body so as to come in contact with wastewater; and a connector, which is electrically coupled to the decomposition electrode, extends through the upper side of the body and is connected with electrochemical measurement equipment.

[8] The electrochemical measurement system of Claim 7, wherein the decomposition electrode is made of any one selected from among a BDD (boron doped diamond) electrode, a Pt/Ti electrode, a carbon/carbon, a carbon/SUS electrode, a carbon/platinum electrode and an Au/Fe electrode.

[9] The electrochemical measurement system of Claim 1, wherein the heavy metal analysis electrode is received in and coupled to the heavy metal analysis electrode-receiving portion so as to come in contact with wastewater introduced into the heavy metal analysis channel, thus analyzing heavy metals in the wastewater.

[10] The electrochemical measurement system of Claim 9, wherein the heavy metal analysis electrode comprises: a body, which corresponds to the shape of the heavy metal analysis electrode- receiving portion and is coupled hermetically to the heavy metal analysis electrode-receiving portion; an analysis electrode, which is provided at the lower end of the body so as to come in contact with wastewater; and a connector, which is electrically coupled to the analysis electrode, extends through the upper side of the body and is connected with electrochemical measurement equipment.

[11] The electrochemical measurement system of Claim 10, wherein the analysis electrode consists of a counter electrode made of Pt, a reference electrode of Ag/ AgCl and a working electrode of BDDE or GCE.

[12] The electrochemical measurement system of Claim 11, wherein the analysis electrode is formed in a shape corresponding to the shape of the lower end of the body, the length ratio of the counter electrode to the reference electrode is 2: 1, and the working electrode having a circular shape is formed in the central portion of the counter electrode and the reference electrode.

[13] The electrochemical measurement system of Claim 1, wherein a pump for supplying wastewater to each of the channels at a specific rate is provided adjacent to the inlet of each of the organic compound-decomposing channel, the heavy metal analysis channel and the discharge channel in the upper side of the upper plate.

[14] The electrochemical measurement system of any one of Claims 1 to 13, wherein a power source-receiving portion for receiving the on/off valve and the on/off switch and an on/off switch-receiving portion for receiving the on/off switch are preferably formed in the upper side of the lower plate.
