METHOD OF DECONTAMINATION OF CIRCULATING WATER OF SWIMMING POOL

methods of multi-stage treatment of water by means of oxidants, ultra-violet radiation and introduction of chemical reagents; cleaning and decontaminating circulating water in swimming pools. SUBSTANCE: proposed method consists of three stages; at first stage hydrogen peroxide is used; at second stage, water is passed through reactor provided with continuous spectrum xenon lamps mainly generating ultraviolet radiation at wave length of 200-400 nm, frequency of 1-1.3 Hz, specific power requirements of 2-5 kJ/cu. m and flux density of 2-7 kW/sq.m; at third stage, solution is introduced containing diammine argentate ions [Ag(NH3)2]+ obtained during electrolysis of water in electrolyzer at periodic change of electrode polarity at content of argentum of no less than 99 mas.% followed by introducing gaseous ammonia or ammonia water till Ag+:NH3, ratio attains 2.8-3.0. Said solution is proportioned in water in the amount corresponding to concentration of argentum in water of 0.005-0.01 mg/l obtaining required ratio of concentration of hydrogen peroxide introduced at first stage and concentration of argentum added at third stage within 200-400;1, respectively. EFFECT: extended functional capabilities; enhanced operational reliability under conditions of increased content of pathogenic bacteria, viruses and fungi. 2 cl, 1 tbl, 2 ex
