Organic wastewater electrolytic treatment device for foam control {ORGANISM WASTE WATER ELECTROLYZING APPARATUS CAPABLE OF REMOVING BUBBLE}

The present invention relates to an organic wastewater electrolytic treatment device for foam control, more specifically, the secondary wastewater does not occur, and in addition, it is possible to minimize the generation of bubbles during treatment, and to control the foam to consume less power It relates to an organic material wastewater treatment apparatus for.

In general, some of the organic substances present in industrial wastewater are treated mainly by microorganisms or chemical methods, but difficult-to-treat wastewaters that are difficult to treat by this method are treated through pretreatment such as ozone treatment and anaerobic acid fermentation (AA / O system). A method for improving the efficiency has been proposed, but the situation is not satisfactory.

In addition, it is difficult to introduce the latest unproven methods or advanced technologies for the treatment of hardly decomposable materials.

Recently, the process of removing organic matter by applying to oxidative decomposition (electrolysis, catalyst) environmental pollution purification technology used in various chemical industries and industries that discharge organic wastewater has environmental preservation problems such as simplification of equipment and minimization of by-products. Is attracting attention as a clean process that can be solved.

Since electrolytic oxidation and reduction reactions occur simultaneously, they can be applied to waste water treatment containing chemical and biologically harmful substances. In order to make the waste water treatment system compact, it is necessary to develop the technology because electrolytic oxidation can be advantageous.

Electrolytic oxidation and electrocoagulation are mainly used in wastewater electrolytic treatment devices, and in the field of electrolytic oxidation, many electrolytic oxidation treatment devices have been developed. However, in the conventional electrolytic wastewater treatment equipment, bubbles caused by bubbles generated at electrodes during electrolysis are used.

With reference to the accompanying drawings, the organic material wastewater electrolytic treatment device for foam control of the present invention formed as described above will be described in detail as follows.

1 is a view showing an organic wastewater electrolytic treatment apparatus for the foam control of the present invention, Figure 2 is a cross-section of the positive electrode plate and the negative electrode plate to induce the flow of the wastewater of the organic wastewater electrolytic treatment apparatus for the foam control of the present invention.

The organic wastewater electrolytic treatment apparatus for foam control according to the present invention primarily supplies wastewater to be treated to the inlet 12 through the wastewater inlet 10.

The wastewater introduced into the inlet 12 flows to the upper side of the inlet 12 after flowing into the wastewater inlet 10 formed at the lower side.

As described above, the wastewater supplied to the inlet 12 is treated by applying power so that the electrolytic treatment is uniformly provided by the negative electrode plate 22 and the positive electrode plate 24 which are formed in plural numbers.

At this time, the characteristics of the wastewater treatment treated by the negative electrode plate 22 and the positive electrode plate 24 are easy to control the residence time of the electrolyte solution, increase the speed of mass transfer, and efficiently remove high concentrations of organic matter and hardly degradable wastewater. .

Electrolytic treatment by the negative electrode plate 22 and the positive electrode plate 24 is characterized in that the residence time of the electrolyte is easily controlled and the material movement speed is increased.

The inlet part 12 is introduced along the inlet part 12 while slowly accepting the wastewater introduced into the wastewater inlet 10. The inlet part 12 flows from the lower side along the waste water inlet 10 and flows upward to the upper side. Is not supplied.

The wastewater overflowing to the upper side of the inlet 12 is moved while slowly sinking to the lower side.

Wastewater flowing down the inlet 12 through the inlet 12 flows between the negative electrode plate 22 and the positive electrode plate 24 for electrolytic treatment.

The upper and lower sides of the negative electrode plate 22 and the positive electrode plate 24 are zigzag, so that the waste water moved up and down flows between the negative electrode plate 22 and the positive electrode plate 24 formed in a lattice form at regular intervals. As shown there is a characteristic that the electrolytic treatment while flowing along the direction of the arrow.

This increases the flow of the waste water, thereby increasing the electrolytic treatment time, thereby improving the treatment state, and of course, reducing the size of the treatment apparatus.

Wastewater that is electrolyzed while flowing between the negative electrode plate 22 and the positive electrode plate 24 draws external air through the bubble generator 16 formed on the lower side to increase the electrolytic effect when it reaches the lower side. As oxygen is supplied, high-density organic matter dissolved in the wastewater and the hardly-decomposable wastewater are treated again.

The treated wastewater is electrolyzed by the bubble generator 16 and the electrolyzed by the negative electrode plate 22 and the positive electrode plate 24, and the bubble which emerges at this time when the waste water is generated generates a lot of bubbles. Since the sprayer 14 sprays the waste water of small fine grains, there is a constitutional feature of popping bubbles away.

Due to the fine grains sprayed by the wastewater nozzle spreader 14 as described above, the bubbles generated during the wastewater treatment are naturally blown away, so there is no need for another foaming process.

The waste water nozzle sprayer 14 is installed on the upper surface of the upper side of the electrolytic treatment apparatus so that bubbles generated by the electrolytic treatment of the anode plate 22 and the cathode plate 24 and the bubbles generated by the bubble generator 16 can be easily processed. do.

That is, the waste water nozzle spreader 14 is formed with a plurality of nozzles on the upper side, bubbles generated in the entire area are easily removed by the water droplets sprayed on the upper side.

In addition, as shown in Figure 2, the grooves 26 are formed on the upper side of the negative electrode plate 22 and the positive electrode plate 24 of the present invention is widened to the contact area of the wastewater to be treated to increase the treatment capacity during the electrolytic treatment You can.

Therefore, the wastewater treated by the organic wastewater electrolytic treatment device for foam control of the present invention treats the grooves in the upper and lower parts of the electrode plate so as to evenly generate for the longest time per contact unit electrolytic condition with the electrode, thereby increasing the treatment capacity. In addition to this, it is possible to achieve miniaturization of the device.

In addition, since the air is blown through the bubble generator to contact the pole plate by the flow of waste water during the electrolytic treatment, the contact amount with the pole plate is increased, thereby increasing the wastewater treatment effect by agitation by aeration and oxidation of air.

In addition, since the bubble generated bubbles are smoothly removed by the wastewater nozzle spreader of the present invention, the wastewater is effectively treated.
