The heads of the three electrode bolts 52 coupled through the blocking plates 12, 22, 32 protrude into the respective cylinders 10, 20, 30, and the electrode bolts 52. The nut hole 53 is formed on the head of the electrode rods 51 are composed of spiral rods are screwed.

One side of the electrode plates 54 is inserted into and coupled to the electrode rod 51, and is fixed by nuts 54a screwed to upper and lower portions of the electrode plates 54.

Electrode plates 54 coupled to respective electrode rods 51 formed in three directions in the cylinders 10, 20, 30 are centered in the outer side of the cylinders 10, 20, 30. They are installed so as to pass through each other so as to intersect with each other in a " * " shape, and the electrode plates 54 are mounted so as not to interfere with each other at different heights.

In some cases, the electrode plate 54 may be formed of a metal mesh on which a platinum plating film is formed. At this time, the platinum-plated metal network acts as a platinum catalyst to activate electrolysis to effectively decompose and treat hardly decomposable materials.

The above-described configuration serves as an electrode unit 50 for applying power of the positive electrode (+) and the negative electrode (-) to the electrode rods 51, respectively.

The water discharge pipe 62 and the inflow pipe 61 are connected to the upper and lower parts of the said container 1, respectively. That is, the support plate 14 is in close contact with the lower portion of the lower blocking plate 12 of the lower cylinder 10 and is fixed by a bolt 80 fastened through the flange 11, and the lower center of the support plate 14 is fixed. The water inflow pipe 61 connected to pass through is connected to the flow hole 12a which is opened in the lower blocking plate 12 so that the water can flow into the lower cylinder 10.

In addition, the support plate 34 is also in close contact with the upper portion of the upper blocking plate 32 of the upper cylinder 30 is fixed by a bolt 80 fastened through the flange 31, the upper center of the support plate 34 The water discharge pipe 62 connected to pass through is in communication with the distribution hole 32a drilled through the upper blocking plate 32 so as to discharge the water introduced into the upper cylinder 30.

Activated carbon 70 filled in the container 1 and water to be purified are mainly injected at a volume ratio of 4: 1, and each electrode 51 is supplied with a power of DC 30 to 70V. It is configured to be disassembled.

According to the present invention having the above-described configuration, the water introduced into the lower cylinder 10 through the lower inlet pipe 61 of the container 1 is provided in the blocking plate 22 and the caps 13, 23, 33. Each cylinder in the process of being discharged through the upper discharge pipe 62 of the container 1 via the intermediate cylinder 20 and the upper cylinder 30 through the through-holes 22a, 13a, 23a, 33a. Chemicals, organic matter, heavy metals, and the like contained in the water are adsorbed and removed by the activated carbon 70 granules filled in the (10), (20), (30), and the water is first purified.

At the same time, water is electrolyzed by the electrolytic action of activated carbon 70 to generate hydroxyl ions (OH ⁻ ) in the upper cylinder 30 and the lower cylinder 10 to which the positive electrode (+) is applied to the electrode 51. In addition, hydrogen ions (H ⁺ ) are generated in the intermediate cylinder 20 to which the negative electrode (−) is applied to the electrode 51.

At this time, according to the electrolyte composition of the myriad of activated carbon 70 specks performing microelectrode role is received evenly to the current generated in the electrode plate 54 is expanded in a radial direction the electrolysis is further activated hydroxyl ions (OH ^-) and hydrogen The supply and recovery of electrons to ions (H ⁺ ) produces intermediates such as hydroxyl [OH˚] and generator hydrogen [H˚], which are present as free radicals with short lifetimes due to discharge of water. It is momentarily combined and stabilized again with water (OH˚ + H˚ = H ₂ O).

The intermediates produced in this way exist as free radicals for a very short time, but in the case of hydroxyl groups [OH˚], they generate a strong oxidizing power equivalent to about 1,000 times the generator oxygen, and the generator hydrogen [H˚] produces strong reducing power. It can generate and clean various kinds of organic materials, heavy metals, chemicals, etc. by adsorption and oxidation treatment.

That is, free radicals, which are intermediates, are instantly oxidized and treated when impurities or organics in the water come into contact with intermediates due to their strong oxidizing power, and carbon and nitrogen compounds contained in organics are oxidized while carbon dioxide and nitrogen gas are oxidized. The heavy metal material contained in the water is separated from the water by electrolysis and is adsorbed onto the porous activated carbon 70 having electric polarity to treat various hardly decomposable substances dissolved in water. It can be strongly oxidized and reduced.

By-products generated through the above-mentioned water treatment process are a small amount of hydrogen, carbon dioxide, and nitrogen gas, so there is no need to use a separate neutralizing agent, and there is no need to replace components such as electrodes 51 or activated carbon 70 for a long time. Since it can be used, there is an advantage such as minimizing the cost of operating the facility.

However, in the case of wastewater containing heavy metals, depending on the concentration of heavy metals, it can be used for about six months without replacing the electrode 51 or the activated carbon 70, which can reduce the considerable cost of wastewater treatment. In addition, the use of the equipment is also very convenient.

The cylinders 10, 20, 30 are different from the installation or upside down, but the structure is the same, so that the overall purification equipment is very easy to manufacture and maintain the manufacturing cost inexpensively, as well as electrode rods in each cylinder After inserting the 51 and screwing the caps and fastening bolts to the flanges, the assembling of the purifier is completed very simply, so that the external competitiveness of the purifier for water quality improvement can be maximized.

In addition, the structure of the purification device is maintained as it is, according to the type of water to be purified or the concentration of heavy metals, the magnitude of the voltage and current applied to the electrode 51, the pH concentration of the water, the feed rate of the water, the electrode plate 54 By controlling the number of the water), it is possible to treat water of various components without regard to the kind of water, so the problems caused by changing the structure of treatment facilities according to the type of water in the prior art are completely solved. There is an advantage such as being.
