This invention relates to the disinfection of xosHucTBeHHo-rafTbeBoft and technical water and can be used as a method for disinfecting any liquid media. Known electrical method. water treatment, which imposes an electric field voltage on the liquid layer, and one of the electrodes is in contact with the flow of the passing liquid, which is the second electrode of the sc. The disadvantages of this method are the low efficiency of the disinfection process, due to the fact that water is treated by ionizing oxygen dissolved in a stream of water whose content is low and energy intensive, as a result of the fact that one of the electrodes is equipped with network cooling. The closest to the invention in technical essence and the achieved result is a method of disinfecting a liquid, which includes processing with high-voltage discharge created over the surface of liquid 2. The disadvantage of this method is a low degree of disinfection of liquid. The goal is achieved by the fact that according to the method of liquid disinfection, including the processing of high-voltage pulsed discharge created above the surface of the liquid, a surface layer of liquid is used as one of the electrodes, and the process is carried out at a high-voltage amplitude the pulse section is 1OO-5OO kV and the liquid layer thickness is 1-5 mm. The method is carried out as follows. Industrial wastewater and other liquids subjected to treatment, after preliminary filtration, are fed into a system of chambers consisting of individual cells, in which the liquid moves in a thin layer, 1-5 mm thick. Oxygenating gas is fed into the reaction chamber above the liquid layer. In the upper part, a chamber made of a dielectric, electrodes are insulated from the walls and connected to a pulse voltage generator, and the process is performed with a phi voltage amplitude of 10 O-5OO kV. In the gap between the electrodes made of a conductive material and the surface layer of decontamination and being the second electrode, a high-voltage pulse discharge is initiated, providing conditions for the formation of temperature. upward tempo -. oxygen-containing gas room. The following ions are formed in the reaction chamber: О, i 3 Т-О ОН and others, arising in the process of continuously following discrete pulse discharges and a number of chemical reactions occur with the additional formation of highly reactive oxidizers. Since the second electrode serves as a direct surface layer underneath the liquid disinfection, it is in contact with the area of intense ionization, as a result of which the oxidation processes are intensified, leading to a reduction in the duration of the disinfection process. Example. The liquid is fed through the pipeline into the reaction chamber and in a thin layer, 1-5 mm thick, poured over a grounded metal bottom of the chamber. The liquid is artificially infected by various types of microorganisms, including Aerobocter cbodcaep Sotmoviota, Aerobac-fcer oero Qfenes. The highest initial score of which, measured in thousands per ml, is 1OOO, SOOO and 9O, respectively. An oxygen-containing gas (technical oxygen) with a content of 0– 93% and) is also introduced into the reaction chamber. In the upper frequencies: cameras on isol - A torus is installed with a composite metal electrode connected to a generator. rum pulse voltages. Between the metal electrode and the surface tone: -. The CMM will sing the liquid being disinfected, which is the second grounded electrode, initiating pulsed high-voltage discharges with the following parameters: voltage rise rate of 10 kV / µs; voltage amplitude 25 kV; the pulse width at half amplitude is 40 µs; the pulse frequency is 20 bits / s. The intensity of liquid disinfection is given in table. I. The limits of the characteristics of the high-voltage pulsed discharge are given in Table. 2. The method of liquid disinfection allows to increase the degree of disinfection. neither liquid, due to the generation of negatives. oyn when exposed im
