Field of the Invention The present invention relates to an electrolyzer for water treatment, and more particularly, to cement-based drainage, filtration of water supply and sewerage, turbid water of sediment runoff by rainfall, purification of closed water areas associated with civil engineering work, and electricity. The present invention relates to a water treatment electrolysis apparatus suitable for application to dust collectors and the like.

2. Description of the Related Art In order to purify muddy water and the like, there is known an electrolyzing apparatus in which a metal is decomposed inside muddy water and the like, dissolved in the muddy water and the like, and the metal component and soil particles are combined and settled. ing. In this electrolysis apparatus, the positive electrode plate is usually electrolyzed by arranging the positive electrode plate and the negative electrode plate to face each other and supplying a current.

In a conventional electrolysis apparatus, a plurality of positive electrode plates and negative electrode plates are alternately arranged at predetermined intervals to face each other, and these electrode plates are held by a frame. Further, in order to supply current to the positive electrode plate and the negative electrode plate which are alternately arranged, an electric connection jig is attached to each of the positive electrode plate and the negative electrode plate. The electric connection jig of the positive electrode plate and the electric connection jig of the negative electrode plate were mounted on opposite sides of each other so that the electric wires did not interfere with each other.

[0004]

However, in the conventional electrolyzer, when the amount of muddy water or the like to be treated becomes approximately 5 m ³ or more, each electrode plate becomes large and the number thereof increases, and a frame for holding the electrode plate increases. There has been a problem that the number of man-hours for assembling and processing the body increases and the cost increases.

In order to increase the efficiency of electrolysis, it is necessary to reduce the electrical resistance by reducing the distance between the electrode plates. However, if the electrode plates are too narrow, there is a risk that adjacent electrode plates may be short-circuited. The distance between the electrode plates could not be so small. Therefore, there is a problem that the electrical efficiency of the electrolysis is low and the power consumption increases.

Further, the distance between each connection jig and the electrode plate on the opposite side is smaller than the distance between each electrode plate. May be dissolved first or a uniform current may not flow between the electrode plates. In such a case, the electrolysis may not be performed normally.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems. The structure can be simplified, cost can be reduced, and electric resistance can be reduced to reduce power consumption. An object of the present invention is to provide an electrolyzer for water treatment that can prevent a portion of a positive electrode plate facing a cathode connection jig from dissolving first and can perform electrolysis normally.

A cathode connection jig for connection, an insulating spacer having a predetermined thickness interposed at a predetermined position between the positive electrode plate and the negative electrode plate, and the positive electrode plate and the negative electrode plate An insulating rod-shaped member is made to penetrate through the spacer, and the positive electrode plate, the negative electrode plate, and the spacer are integrally fixed using the rod-shaped member.

In this electrolyzer for water treatment, each electrode plate and the spacer are integrally fixed by a rod-shaped member penetrated through each electrode plate, so that it is necessary to use a frame or the like for holding each electrode plate. Disappears. Further, since the spacer is interposed at a predetermined position between the electrode plates, it is possible to prevent the electrode plates from contacting each other even when the interval between the electrode plates is reduced.

[0010] A predetermined range of the positive electrode plate including a range facing the cathode connection jig can be cut out. In this case, since there is no portion of the positive electrode plate facing the cathode connection jig, this portion can be prevented from being melted first, and current can be uniformly applied to the opposed electrode plate.

Further, in the present invention, in order to remove soil particles contained in muddy water and the like, a metal is electrolyzed in the muddy water and the like and dissolved in the muddy water and the metal is combined with the soil particles.
