FIELD: animal breeding.
SUBSTANCE: invention relates to aquatic animals breeding. Method consists in drainage of circulating water from pools with aquaculture into discharge pipeline, movement of circulating water from pools into mechanical filter, movement of circulating water from the mechanical filter to the biological filter, movement of circulating water from the biological filter to the summation pool where the circulating water is mixed with make-up water. Replaced circulating water is discharged through the overflow pipeline. Further, water from the summation poo is fed into an oxygenator by means of a pump, and water which has passed through the oxygenator is supplied to the pool via a supply pipeline. From the summation pool, circulating water is additionally supplied to the device for mixing ozone-oxygen mixture with water, in which circulating water is saturated with ozone-oxygen mixture with ozone content from 4 to 5 mg/l. After that, circulating water saturated with ozone-oxygen mixture is supplied to the discharge pipeline through the circulating water discharge point located at the point of discharge of contaminated water from the first basin. Amount of water supplied from the device for mixing the ozone-oxygen mixture with water to the discharge point ranges from 10 to 15 % from the total volume of recycled water in the closed water supply device.
EFFECT: higher quality of disinfection of circulating water in closed water supply plants, as well as reduced duration of treatment of circulating water.
