FIELD: water supply.SUBSTANCE: invention relates to treatment of water with ozone and can be used in urban water supply systems and settlements for disinfection of drinking water from surface water sources, in particular, with large seasonal variations in degree of water pollution. Disclosed method of installation and at same time increase growth of total number of micro-holes for dispersing its consumption of ozone-air mixture is produced. For small doses of ozone, including minimum, a minimum number of base contact tanks continuous-operation, minimum specific consumption of ozone-air mixture through contact tank 1 and minimum concentration of ozone in it, and at higher doses, including maximum, additional amount of contact of reservoirs of periodic action, besides, at connection of each additional contact tank are redistributed and alignment of treated water flow rate between active contact tanks, as well as increased specific consumption of ozone-air mixture through one contact tank stages with equal pitch, calculated based on double permissible exceeding minimum specific consumption of received to provide minimum preset ozone dose.EFFECT: technical result consists in design simplification and improvement of reliability of dispersion of ozone-air mixture due to use of common metal dispersers of titanium, reducing cost of equipment due to reduction of total amount of dispersers and shutoff-control equipment, longer service life due to use of contact of reservoirs of periodic action for rotation of permanently acting, as well as in above-limit increase of total consumption of treated water due to use of additional free contact of reservoirs at low and medium doses of ozone.2 cl, 11 dwg, 7 tbl, 1 ex |
