DEVICE FOR WATER PURIFICATION AND DISINFECTION Russian patent published in 2009 - IPC C02F1/467 

FIELD: purification constructions.

SUBSTANCE: invention relates to field of water treatment, in particular to water purification from organic and inorganic admixtures, toxic pollutants, disinfection from pathogenic microflora and can be used at autonomous units, in steady-state and field conditions. Device includes reactor for treated water which contains gap-arrestor with at least one pair of electrodes contacting directly with treated water, input and output branch pipes, generator of pulse voltages, compressor of blown through intra-electrode space gas. Electrodes in pair are placed above each other on different bases, one of which is dielectric, electrode placed in electro-conducting base, being made hollow with calibrated holes for gas supply into intra-electrode space, and the other electrode being made flush with dielectric, making gap-arrestor with several pairs of electrodes, connection of pairs is made parallel, in device included are additional gap-arrestor, generating nano-second corona-discharge, and at least two sparkle-gaps generating air sparkle discharge, which are made with at least one pair of electrodes and are placed in outlet branch pipe, electrode which is made flush with dielectric, being switched to generator of pulse voltages through one of sparkle-gaps, generating sparkle air discharge, and one of electrodes of sparkle-gap, generating nano-second corona discharge, being switched to generator of pulse voltages through other sparkle-gap, generating sparkle air discharge, when making nano-second corona sparkle-gap with electrodes included in parallel way, they are also switched through separating element and are placed above the surface of treated water, electrode of sparkle-gap which is in direct contact with treated water and placed on electro-conducting base, is one of electrodes for sparkle-gap, generating nano-second corona discharge.

EFFECT: device allows to increase efficiency of water purification and disinfection.
