FIELD: water purification.
SUBSTANCE: invention relates to the purification of water from various contaminants. The method for hydrodynamic water purification includes electropulse treatment, which is performed by alternately generating antiphase pulses applied to groups of coiled electrodes of at least two electrolytic capacitors included in water treatment in series. A positively charged pulse is applied to one group of electrodes, and a negatively charged pulse is applied to the other group of electrodes at this time, then the pulses are changed to oppositely charged ones, while the water passing through the pipe gap located between the electrode groups, free from electrodes, is simultaneously affected by positive and negative impulses. The longitudinal elastic ultrasonic pulses formed from these processes from the resonant rotation of water dipoles and the counter-reciprocal motion of ions under the action of the generated current pulses along the pulse fronts enhance the process of destruction of ion hydration shells in both directions along the pipe and initiate the onset of the process of cross-oxidation-reduction reactions between free from hydration shells with pollutant ions. Next, water is fed into the conoidal nozzle to form a high-speed water jet, while a vacuum is created in the injection chamber to suck air into the water jet, and a mixing zone of microbubbles is created in the diffuser, which, together with the water jet, are separated from the diffuser walls and destroy the longitudinal integrity under pressure drop jet into separate fragments, keeping the cross section of the jet from touching the walls of the diffuser, after which artificially formed cavitation is performed due to the impact of high-speed air-saturated water drops on a target located perpendicular to the water flow, in this case, multiple cross-reactions occur between the released ions of water pollution, low-temperature boiling and degassing occurs, some of the crystals coagulate and are captured by the resulting air bubbles due to the flotation effect. The device for hydrodynamic water purification contains a means for electropulse water treatment, which is made in the form of two series-connected electrolytic capacitors, consisting of a paired group of coiled electrodes, spirally located on the outer side of the inlet pipe, while between the groups of coiled electrodes there is a section of the inlet pipe free from electrodes. The confuser is made in the form of a conoidal nozzle, and the transition neck is made in the form of an expanding vacuum zone, equipped with a nozzle for air supply. The device is equipped with an elastic target located in the path of the water flow at an adjustable distance from the diffuser.
EFFECT: improving the efficiency and quality of water treatment when operating in safe modes.
