The present invention relates to an electrochemical wastewater treatment apparatus for treating wastewater and sewage using an ionization reaction between electricity and metal, and in particular, the cleaning inside the chamber is automatically performed, and the blades mounted inside the chamber can be replaced smoothly. The present invention relates to an electrochemical wastewater treatment device that can be implemented.

Recently, as the interest on the environment is rapidly increasing, the problem of discharging sewage and wastewater including heavy metals and various other inorganic materials is emerging as a big social problem. Accordingly, an attempt to efficiently treat such wastewater has been attempted. It is multifaceted.

Currently, an apparatus using electrocoagulation has been proposed as an efficient method for purifying wastewater. As for such a device, U.S. Pat. Nos. 47,472,10, 500,4531, 6,665,921, 6,383,98, 6,367, 6719894 and the like. These wastewater treatment devices basically purify the wastewater by passing the wastewater between the blades of the high-voltage metal material to combine the ionized metal and the contaminants to aggregate or solidify the wastewater.

In particular, Korean Patent Registration No. 395531 introduces an efficient device for implementing the electrocoagulation method. This device installs a plurality of blades vertically in the chamber and supplies wastewater from the lower side to the upper side of the chamber so that it can be continuously purged. In particular, the device is arranged in parallel with the supply direction of the waste water so that the wear of the blade can be minimized while being uniform.

However, the wastewater treatment apparatus introduced in the related art has the following problems.

1. The conventional wastewater treatment apparatus does not have any means for cleaning the chamber.

In general, the wastewater treatment system employing the electrocoagulation method is used to purify the wastewater using a combination of metal ions and contaminants. A large amount of scale (scale) is generated on the side or the like of the foreign matter is attached to accumulate. In addition, if the scale or foreign matter generated and attached to the surface of the chamber or the blade is left in this manner, the amount of metal ions released from the blade decreases, and the flow of wastewater flowing through the narrow space between the blades By being disturbed by the wastewater efficiency is reduced.

Therefore, after the purification process is performed for a predetermined time using the wastewater treatment device, it is necessary to remove scales and foreign substances attached to the inside of the chamber and the side of the blade. However, since the blade is densely provided in the chamber and the blade is installed vertically along the depth direction of the chamber, it is very difficult to clean the inside of the chamber.

2. Since the conventional wastewater treatment apparatus is to be purged using metal ions discharged from the blade, the thickness of the blade becomes thinner as the wastewater treatment is performed. Thus, the blades need to be replaced at regular intervals.

However, in the conventional apparatus as described above, since the blade is installed along the longitudinal direction of the chamber, when the blade is replaced, the upper cover of the chamber should be opened and the blade should be inserted or withdrawn through the upper side. That is, there is a problem that replacement of the blade is very difficult.

3. In general, a large amount of coagulum condensed with contaminants is present in the effluent discharged through the chamber, so it is necessary to separate such coagulum from the effluent. Conventionally, as a method of separating the coagulum, a method of depositing the coagulum by storing the discharged water from the chamber in a large water tank is adopted.

However, such a method requires a large reservoir and also takes a long time to separate the coagulum.

Accordingly, an object of the present invention is to provide a wastewater treatment apparatus, which has been created to solve the above-described problems, and which is capable of easily carrying out washing in a chamber.

In addition, another object of the present invention is to provide an electrochemical wastewater treatment apparatus that can easily replace the blade installed in the chamber.

In addition, the present invention is characterized in that the sensor for detecting the storage amount of the washing water is provided on the upper side of the washing tank.

In addition, the present invention is characterized in that the washing water discharged from the chamber is recovered back to the washing tank by the pipe.

Manual valves and electric valves not mentioned in each of the above states are kept closed.

 The operation of the device having the above configuration will be described below.

First, the wastewater treatment operation through the chamber 10 will be described.

When the operator operates the control panel 70 to select the wastewater treatment function, the control panel 70 opens the electric valve V1 and the electric valve V2 as described with reference to FIGS. 15 and 16, and the pump P1. ). Accordingly, the wastewater flows into the chamber 10 through the manual valve 1V, the electric valve V1, the pump P1, the electric valve V2, and the manual valve 5V from the wastewater inlet 421. In addition, in this case, the control panel 70 applies a predetermined voltage to the electrode 150 of the chamber 50 and drives the air supply to the inside of the chamber 10 through the air inlet pipe 170 of the chamber 10. To supply ultra-fine bubbles.

The wastewater introduced into the chamber 10 is mixed with the ultra-fine bubbles discharged through the air inlet pipe 170 and then rises between the blades 160 to treat the treated water discharge part 112 and the treated water discharge pipe 110a. Is discharged through.

Subsequently, the treated water discharged to the treated water discharge pipe 110a is stored in the buffer tank 31 in FIG. 1, and the stored treated water is supplied to the cyclone 32 through the pump P2 as described above. And the separation process for the coagulum is performed.

Meanwhile, as shown in FIG. 1, a plurality of water level sensors 311 to 313 are installed in the buffer tank 31. These water level sensors 311 to 313 are for detecting the amount of treated water stored in the buffer tank 31. The detection signals of the water level sensors 311 to 313 are supplied to the control panel 70, and the control panel 70 controls the driving speed of the pump P1 based on the detection signals of the water level sensors 311 to 313. . That is, the amount of wastewater introduced into the chamber 10, that is, the amount of wastewater treated through the chamber 10 is appropriately adjusted.

On the other hand, if the above series of wastewater treatment lasts for a predetermined time or more, the washing process for the chamber 10 is executed. This washing process is performed by the operator operating the control panel 70 or automatically by the control panel 70.

15 and 16, the control panel 70 first opens the electric valves V4 and V3, and drives the pump P1 while the other electric valves are closed. Accordingly, the wastewater inside the chamber 10 is discharged to the wastewater outlet 424 through the manual valve 5V, the electric valve V4, the pump P1, and the electric valve V3.

After the above operation is continued for a predetermined time and all the waste water in the chamber 10 is discharged, the control panel 70 opens the electric valves V5 and V2 and drives the pump P1 with the other electric valves closed. Done. Accordingly, the wash water flows into the chamber 10 from the washing tank 20 through the manual valve 6V, the electric valve V5, the pump P1, the electric valve V2, and the manual valve 5V. The control panel 70 performs washing water input to the chamber 10 while detecting the level of the washing water through the ultrasonic sensor 10 installed above the chamber 10.

When the washing water is introduced into the chamber 10 in a proper amount, the pumps P1 are driven while the motor valves V4 and V6 are opened and the other motor valves are closed. Accordingly, the washing water in the chamber 10 is recovered to the washing tank 20 through the manual valve 5V, the electric valve V4, the pump P1, and the electric valve V6. That is, the washing water stored in the washing tank 20 is recovered again after washing the chamber 10 and used repeatedly.

Subsequently, when the washing water recovery is completed from the chamber 10 to the washing tank 20, the control panel 70 opens the electric valves V7 and V2 and drives the pump P1 while the other electric valves are closed. Accordingly, in this case, tap water is introduced from the tap water inlet 423 and into the chamber 10 through the manual valve 3V, the electric valve V7, the pump P1, the electric valve V2 and the manual valve 5V. Inflow. The control panel 70 executes tap water inflow on the basis of the water level sensor 90 provided above the chamber 10, and when the tap water level in the chamber 10 reaches a predetermined level or more, the electric valve V2 is opened and other electric power is supplied. The valve discharges the tap water in the chamber 10 in a free-falling manner through the wastewater outlet 425 in a blocked state.

The washing of the chamber 10 using the tap water is repeated several times if necessary.

On the other hand, after using the washing water stored in the washing tank 20 more than a predetermined number of times, the washing water stored in the washing tank 20 is discarded and filled with new washing water again.

Disposal of the washing water is made through the free fall method from the washing tank 20 to the washing water inlet 422. That is, when the operator operates the control panel 70 and selects waste water disposal, the control panel 70 opens the electric valve V5 and closes the other electric valves. Therefore, in this case, the washing water is discharged from the washing tank 20 to the washing water inlet 422 through the manual valve 6V, the electric valve V5, and the manual valve 2V.

Subsequently, after the washing water discharge process is completed, the operator operates the control panel 70 to select the washing water filling function, and when the washing water supply pipe is connected to the washing water inlet 422, the control panel 70 is an electric valve. The pump P1 is driven while the V6 is opened and the other electric valve is closed. Therefore, in this case, the washing water is filled in the washing tank 20 through the manual valve 2V, the pump P1, and the electric valve V6. Then, when the washing water 20 is filled in the washing tank 20 by the above-described filling operation, the control panel 70 detects this by the ultrasonic sensor 22 installed above the washing tank 20 to stop the driving of the pump P1. By doing so, the washing water filling to the washing tank 20 is terminated.

Hereinafter, the blade replacement operation in the chamber 10 will be described.

The blade replacement operation is first performed after the wastewater in the chamber 10 is discharged.

That is, the operator first selects the wastewater discharge function for the chamber 10 by operating the control panel 70. Then, the control panel 70 naturally discharges the wastewater in the chamber 10 through the wastewater discharge port 425 by opening the electric valve V2 and closing the other electric valve as described above.

When all the wastewater in the chamber 10 is discharged by the above operation, the operator removes the power line coupled to the electrode 150 of the chamber 10 and the water level sensor 90 coupled to the upper side of the chamber 10. The wastewater inlet pipe 411 is separated from the wastewater inlet 113 below the chamber 10, and the air supply coupled to the air inlet pipe 170 is separated.

Subsequently, as shown in FIGS. 17 and 18, the chamber 10 is rotated about the rotation shaft 131. At this time, the chamber 10 is not rotated by more than 90 degrees by the washing tank support 82. With the chamber 10 rotated 90 degrees, the chamber cover 120 is opened, the blade 160 is drawn out horizontally, the new blade 160 is inserted into the chamber 10, and the cover 120 is closed again. .

And, contrary to the above-described operation, after rotating the chamber 10 in the vertical direction, the water level sensor 90 is installed on the upper side of the chamber 10, and the wastewater inflow pipe 411 is again below the chamber 10. In addition to connecting to the power line to the electrode 150. In addition, the blade replacement operation is terminated by connecting the air supply to the air inlet pipe 170 below the chamber 10.
