The present invention relates to a water treatment device capable of suppressing the generation of scale, iron rust, slime, and the like, and significantly improving the efficiency of dissolving and mixing gas used in a subsequent step into treated water.

配管系の閉塞事故を引起こす場合がある。(Prior art) In general, hardness components such as iron, calcium, and magnesium, and electrolytes are contained in water, and the water is supplied to a boiler, a cold water tower, or other heat exchange devices, or makeup water or wastewater treatment water. If used as it is, iron rust and scale are generated in the device, reducing heat transfer efficiency,
This may cause a blockage accident in the piping system.

成分を酸化して不溶態にし、析出沈殿物として分離する
方法がある。Therefore, an operation of previously removing the hardness component by a chemical addition treatment, a coagulation sedimentation treatment, or an aeration treatment with air is carried out. For example, there is a method of adding hypochlorous acid as an oxidizing agent to water to oxidize ferrous ions and hardness components dissolved in water to make them insoluble and to separate them as a precipitate.

離する方法が採用されている。On the other hand, as an aeration treatment method using air, the air is pressed into the water with a large blower, the water and air are brought into countercurrent contact in a Raschig ring packed tower, or the water surface is mechanically stirred by a rotating propeller into the water. A method is adopted in which oxygen is dissolved and the hardness component is deposited and separated by the dissolved oxygen.

分散混合する方式が一般に採用されている。In addition to the operation for removing the hardness component, mixed gas such as air may be fed into the water in order to increase the amount of dissolved oxygen in the wastewater treatment water. Even in this case, the mixed gas is sent into the water by a blower or a mechanical stirrer,
A method of dispersing and mixing is generally adopted.

ストが高騰する問題点がある。(Problems to be solved by the invention) However, in the conventional method of adding hypochlorous acid, it is necessary to remove hypochlorous acid remaining in the treated water after the completion of the oxidation reaction. Because hypochlorous acid is
This is because it is harmful to the human body and plants and has a very strong effect of generating rust on the metal material constituting the equipment. However, in order to highly remove the residual hypochlorous acid, for example, an adsorption treatment with activated carbon is required, but since the regeneration cost of activated carbon is very expensive, there is a problem that the treatment cost rises.

に侵入することができないためと考えられる。On the other hand, when performing aeration treatment with air using a mechanical device such as a blower or a stirrer, or when preparing treated water with a high dissolved oxygen concentration, there is a drawback that the dissolution efficiency of oxygen in water is extremely low. . The cause of this is that the H atom or O atom of another water molecule having an opposite charge to the positive and negative charge positions of the polar water molecule associates with each other through a hydrogen bond and behaves like a polymer compound. As a result, it is considered that the supplied oxygen molecules cannot easily penetrate between the associated water molecules.

率が低く処理コストが高くなる欠点がある。Therefore, the dissolution efficiency of oxygen in water is about 1 to 10%, and there is a drawback that the supply efficiency of oxygen to the required power of the blower and the stirrer is low and the processing cost is high.

の伝熱面にスケールとして付着することが少ない。(Operation) In the water treatment device according to the above configuration, the water to be treated that has flowed into the opposite electrode is partially polarized continuously due to the cell action between the opposite electrodes to be ion-activated. Then, the electrolytes such as iron and manganese dissolved in water and the hardness components such as calcium, magnesium and silica are efficiently oxidized by the oxidizing action of the activated ions to be precipitated as insoluble substances in water or colloids. Become particles,
Floats in water. Therefore, hardness components and the like are less likely to adhere to the inner surface of the piping system and the heat transfer surface of the device as a scale.

の被混入ガスの溶解効率が大幅に向上する。At the same time, a large number of associated water molecules in the water to be treated that have flowed into the opposite electrode part are released from the association state by the cell action and become a fine aggregate of independent water molecules. Therefore, the mixed gas supplied into the main body of the water treatment device through the supply pipe is
It becomes possible to easily penetrate between water molecules, and the efficiency of dissolving the gas to be mixed in the treated water is greatly improved.

とはない。Further, the opposite electrode is composed of a carbon rod arranged in the central axis direction in the water treatment device main body and a cylindrical aluminum electrode plate arranged so as to surround the carbon rod,
Since only an electromotive force (about 0.7 V) that is less than the decomposition voltage of water is generated between both electrodes, flammable hydrogen gas is not generated.

機器の伝熱面にスケールとして付着することが少ない。As described above, in the water treatment apparatus according to the present invention, a part of the water to be treated that has flowed into the opposite electrode is continuously ion-activated by the cell action between the opposite electrodes. Then, the electrolytes such as iron and manganese dissolved in water and the hardness components such as calcium, magnesium and silica are efficiently oxidized by the oxidizing action of the activated ions to become insoluble substances and precipitate in water or colloids. It becomes particles and floats in the water. Therefore, hardness components and the like are less likely to adhere to the inner surface of the piping system and the heat transfer surface of the device as a scale.
