Abstract

In a liquid treating process according to the present invention, colloidal particles in stable hydrated states or in meta-stable hydrophobic colloidal states in a liquid are rendered hydrophobic and separated from liquid molecules by an electric field formed by a microwave. The separated colloidal particles are allowed to collide against one another to become flocculated under a cavitation effect by a ultrasonic wave having a frequency in a low frequency range, and the liquid is deodorized by an electromagnetic ultrasonic wave having a frequency in a high frequency range. Therefore, it is possible to easily and reliably remove the colloidal particles dissolved in the liquid and to deodorize the liquid without need for a large-scaled equipment. For this purpose, the microwave which is an electromagnetic wave is emitted to the liquid containing the colloidal particles of water-soluble organic substances, microorganisms and the like to separate the colloidal particles from the liquid molecules and then, a ultrasonic wave having a frequency in a low frequency range is emitted to the liquid resulting from the separation of the colloidal particles to flocculate the colloidal particles, and an electromagnetic ultrasonic wave having a frequency in a high frequency range is emitted to the liquid to deodorize the liquid.

Dependent claims

A liquid treating process comprising the steps of emitting an electromagnetic wave to a liquid containing colloidal particles of water-soluble organic substances and microorganisms to separate said liquid into the colloidal particles and liquid molecules, emitting an ultrasonic wave to the liquid resulting from the separation to flocculate said colloidal particles, emitting an electromagnetic ultrasonic wave at a higher frequency than said ultrasonic wave to said liquid to deodorize said liquid, and separating the flocculated colloidal particles from the liquid by allowing the flocculated colloidal particles to settle.

A liquid treating system comprising:

a flocculating device having an electrically charging/cell-destructing means which includes an AC high-voltage electrode means for applying a high-voltage pulse to separate and flocculate colloidal particles of water-soluble organic substances and microorganisms from a colloidal particle-containing liquid and to destruct cells of the microorganisms;
a flocculation accelerating device which includes a microwave separating means for emitting a microwave which is an electromagnetic wave to said liquid to separate said liquid into the colloidal particles and liquid molecules, a first ultrasonic wave flocculating means for emitting a ultrasonic wave of a frequency in a range of 40 k to 1,200 kHz to the liquid treated by the emission of the microwave, thereby flocculating said colloidal particles, and a deodorizing means adapted to emit an electromagnetic ultrasonic wave to said liquid;
and
a settling device which includes a flocculate settling means adapted to pass the liquid containing flocculates of said colloidal particles through a lattice-shaped electrically separating membrane having a high voltage applied thereto, thereby adsorbing the flocculates to the electrically separating membrane, and settling the flocculates by changing the direction of application of the high voltage.
