A pair of electrolytic electrodes 31, 3 are provided on both sides of the solid electrolyte membrane 33.
An electrolysis chamber E is provided in which the positive electrolytic electrode 31 is placed in contact with water and a DC voltage is applied to both electrolytic electrodes 31 and 32 to electrolyze water and generate oxygen and a small amount of ozone. Ionization electrode plates 5, 6 and electrolytic electrodes 31, 3
No. 2 is a technical means characterized in that it is connected in parallel to the output end of a power supply control section 25 that controls opening/closing and increasing/decreasing of the DC power supply 7.
『作用』
それ故、本考案水のイオン化装置は、電気分解

さらには吸着槽２０の途中に配設した場合で次の
ように作用する。"Function" Therefore, the water ionization device of the present invention has the electrolytic chamber E located upstream or downstream with respect to the adsorption tank 20.
Furthermore, when it is disposed in the middle of the adsorption tank 20, it works as follows.
先ず、図示実施例のごとく電気分解室Ｅを吸着

半部位まで通過する。そして、オゾンは強力な酸
化力を有するため、塩素が吸着された吸着剤２４
の後半部位では該塩素にかわつて殺菌剤として作
用する。 First, as in the illustrated embodiment, the electrolysis chamber E is arranged upstream of the adsorption tank 20. In this case, oxygen and ozone are generated as bubbles in the raw material water in the electrolysis chamber E. The raw water mixed with air bubbles flows into the adsorption tank 20, and chlorine, etc. in the raw water is adsorbed by the adsorbent 24. On this occasion,
At the same time, some of the ozone comes into contact with the adsorbent 24 and decomposes into oxygen, but if the adsorbent 24 is wet, the ozone in the gas phase has less opportunity to directly contact the adsorbent 24, and most of it is decomposed. It passes through to the latter half of the adsorption tank 20 without any trouble. Since ozone has strong oxidizing power, the adsorbent 24 on which chlorine is adsorbed is
In the second half, it acts as a disinfectant instead of the chlorine.
次に、吸着槽２０の途中に電気分解室Ｅを配設
した場合、すなわち、吸着槽２０を電気分解室Ｅ
の下流側と上流側とに一対配設する場合である

の吸着槽２０で吸着されるようになしておくこと
で、該下流側の吸着槽２０では塩素濃度は極端に
低いがオゾンが殺菌剤となり雑菌の繁殖を防ぐよ
うに作用する。 Next, when the electrolysis chamber E is arranged in the middle of the adsorption tank 20, that is, the adsorption tank 20 is placed in the electrolysis chamber E.
In this case, chlorine, etc. is not completely removed in the upstream adsorption tank 20, and the remaining chlorine, etc. is disposed in the downstream adsorption tank 20. By allowing ozone to be adsorbed, although the chlorine concentration is extremely low in the adsorption tank 20 on the downstream side, ozone acts as a disinfectant and prevents the growth of bacteria.

止し得ないが、この吸着槽２０を出て処理槽１に

れるという作用を呈するものである。 Furthermore, if the electrolysis chamber E is arranged downstream of the adsorption tank 20, the proliferation of various bacteria within the adsorption tank 20 cannot be prevented, but until it leaves the adsorption tank 20 and flows into the treatment tank 1. During this time, ozone exhibits the effect of sterilizing bacteria.
なお、原料水に溶解したオゾンは、イオン化電
極５，６の放電界の影響を受けると酸素に分解さ
れる作用を呈することが認められた。 It has been found that ozone dissolved in the raw water exhibits the effect of being decomposed into oxygen when affected by the discharge field of the ionizing electrodes 5 and 6.
また、本考案の電源制御部２５は、直流電源の

う作用するものである。 Further, the power supply control unit 25 of the present invention is configured to increase or decrease the DC power supply, and increasing the DC power supply, in other words, increasing the voltage applied to the ionization electrodes 5 and 6 is performed when the raw water is supplied. Needless to say, this is to perform the prescribed ionization even when the feeding rate is increased, but at the same time, the electrolytic electrodes 31 and 32 are
By increasing the voltage applied to the pump and increasing the amount of ozone generated, the amount of ozone mixed in per unit flow rate is made approximately uniform.
『実施例』
次に、本考案の実施例を添附図面に従つて説明
すれば以下の通りである。``Example'' Next, an example of the present invention will be described below with reference to the accompanying drawings.

室Ｂと電極間隙室Ｃとに仕切つてある。 In the figure, reference numeral 1 denotes a processing tank formed in the shape of a container, and a pair of ionization electrode plates 5 and 6 are housed within this processing tank 1. Conventionally, the ionizing electrode plates 5 and 6 are constructed by partitioning the inside of the treatment tank 1 into a positive electrode chamber A' and a negative electrode chamber B' with a semi-water-permeable membrane 10 made of synthetic resin non-woven fabric, etc., as shown in FIG. The semi-water-permeable membrane 1 is provided oppositely at a predetermined distance on both sides of the water-permeable membrane 10.
0 separates ionized water,
The present invention may also adopt this method, but in the illustrated embodiment, the semi-water permeable membrane 10 is omitted, and the positive ionizing electrode plate 5 and the negative ionizing electrode plate 6 are directly opposed to each other, and the processing tank 1 is The inside is partitioned into a positive electrode plate rear chamber A, a negative electrode plate rear chamber B, and an electrode gap chamber C.

に多少の変化を持たせても差し支えはない。 The positive ionized electrode plate 5 and the negative ionized electrode plate 6 may be made of any conductive material, but since the ionized water is used as drinking water, it must be rust resistant. Also, it is desirable that the material has little discharge wear and tear, and titanium or the like is usually used. Note that the positive ionizing electrode plate 5 and the negative ionizing electrode plate 6 are normally arranged in parallel with a predetermined gap, but the gap may vary slightly between the upstream and downstream sides. There is no problem.

Each hole has been opened. This through hole 8, 8, 8...
is a circular hole in the illustrated example, but the purpose of providing this hole 8 is to omit the above-mentioned semi-water permeable membrane 10, and instead to provide this hole in the positive ionizing electrode plate 5 and the negative ionizing electrode plate 6. It serves the function of the semi-water permeable membrane 10, and communicates between the electrode gap chamber C and the positive electrode plate rear chamber A, and between the electrode gap chamber C and the negative electrode plate rear chamber B, and also connects the positive electrode side ionizing electrode plate 5 with the negative electrode plate. Since a corner portion is provided on the side ionization electrode plate 6 where a large amount of the discharge field is concentrated, there is no need to limit its shape in particular, and it may be changed to small holes, slits, etc. of various shapes.

A second drain port 4 is provided. That is, the raw water P flows from one end of the treatment tank 1 to the electrode gap chamber C.
Some of the water is injected into the back chamber A of the positive electrode plate through the through hole 8 of the ionizing electrode plate 5 on the positive electrode side, and the other part is injected into the rear chamber A of the negative electrode plate through the through hole 8 of the ionizing electrode plate 6 on the negative electrode side. It is arranged so that it flows into B, and furthermore,
