METHOD AND DEVICE FOR UV TREATMENT OF LIQUID, AIR AND SURFACE

The present invention relates to the decontamination and cleaning technology for fluid media and surfaces and can be used to decontaminate air in dwellings, eliminate organic and bacterial impurities in drinking water and waste water, but also disinfect and sterilize surfaces, including human skin surfaces. According to the suggested method, liquid, air and surfaces are submitted to dense spectrum ultraviolet radiation with a pulse duration of 10 to 10 sec. and a radiation intensity of at least 100 kWt/m , using a plasma radiation source with a pulsed storage element characterized in that the energy stored in the storage element at the time of discharge, the pulse duration and the area of the radiating surface of the radiation source are interrelated as follows: Wo/A Sray tau 1/2 > 1, where Wo is the energy stored in the storage element, Joules; Sray is the area of the radiating surface of the radiation source, m ; tau 1/2 is the radiation pulse duration at mid-height of a peak, sec.; A=10 Wt/m is the constant coefficient. The UV treatment device for liquid, air and surfaces comprises a pulsed gaseous discharge lamp, a feeding and control unit provided with a high voltage source of continuous current and a charged condenser, as well as a surge generator and a pulse transformer on a ferrite core. A secondary winding is integrated in a series with the charged condenser and the pulsed lamp to form a discharging circuit, the parameters of which are interrelated as follows: 0,05 < (U /B d h) 2ROOT C/L0 < 1, where U is the voltage in the pulsed storage element, volts; C is the charge of the pulsed storage element, Faraday; L0 is the initial inductance of the discharging circuit, i Henry; d is the inner diameter of the gaseous discharge lamp, m; h is the distance between the electrodes of the plasma radiation source, m; and B=10 Wt/m is the constant coefficient. La présente invention touche à la technique de décontamination et de nettoyage des milieux et surfaces fluides et peut s'utiliser pour décontaminer l'air dans les habitations, éliminer les impuretés organiques et bactériennes dans l'eau potable et les eaux usées, mais aussi désinfecter et stériliser les surfaces, y compris les surfaces de peau humaine. Le procédé proposé prévoit le traitemnet de liquide, d'air et de surfaces par rayonnement ultraviolet à forte densité spectrale, d'une durée d'impulsion de 10 à 10 secondes et d'une intensité de rayonnement d'au moins 100 kWt/m , en utilisan
