Water treatment device

Abstract

The invention provides a water treatment device capable of improving the treatment efficiency of the treated water and passing the treated water once to sufficiently treat the water without repeated circulation, and the water treatment device (1) includes a water passing first electrode (6) arranged in the channel of the treated water, a conductive fiber (8) positioned on the downstream side of this first electrode (6) and energized by the first electrode (6), a water passing electrode (7) positioned on the downstream side of this conductive fiber (8) and forming a pair with the first electrode (6), an insulating porous spacer (9) interposed between this electrode (7) and the conductive fiber (8), and a supply section which supplies voltages to both of the electrodes (6, 7).

Description

technical field [0001] The present invention relates to water treatment for removing microbes such as viruses contained in water (water to be treated) contained in rivers, drinking water, or swimming pools, public baths, hot springs, etc., or for removing scale device. Background technique [0002] In recent years, water treatment technologies for removing microorganisms such as bacteria, mold, and protozoa contained in rivers, drinking water, or water used in swimming pools, public baths, hot springs, etc. (water to be treated) have been rapidly developed. [0003] As a kind of such water treatment device, the applicant has previously developed a conductor that can be equipped with a pair of electrodes and microorganisms in the flow path of the water to be treated, and a positive charge is applied to the conductor, and a negative charge is applied to the electrode. , so that microorganisms are adsorbed on a conductive device (for example, refer to Patent Document 1).

AI Technical Summary

Problems solved by technology

[0006] However, in the above-mentioned water treatment device, microorganisms can be adsorbed and removed, but due to the low current density applied to the electrodes, the sterilization of microorganisms based on electric shock or hypochlorous acid cannot be realized, and the conductor needs to be taken out periodically. Chemicals remove microorganisms adsorbed on conductors, making maintenance and management complicated

[0007] In addition, in consideration of adsorption and removal of most of the microorganisms in the water to be treated, it is necessary to pass through the device several times, or when passing through the water once (one-time pass), so that no stronger than Coulomb force occurs in the microorganisms. The degree of force of the very slow flow rate through etc. deal with the problem of very inefficiency

This is because the surface of the conductor is uneven, which leads to uneven charging on the surface of the conductor and reduces the adsorption efficiency of microorganisms.

Furthermore, since the contact resistance between the conductor and the first electrode energized is insufficient, the contact resistance between the conductor and the first electrode energized becomes high, resulting in a decrease in current efficiency.
