FIELD: technological processes.
SUBSTANCE: invention is related to the field of water treatment and may be used for preparation of drinking water, treatment of industrial and household waste water. Method for disinfection and treatment of water consists in water treatment in the main water reservoir, such as river, by radiation of progressive hydroacoustic waves of sound range of frequencies, in three subsequent settling tanks - by radiation of standing hydroacoustic waves of sound and ultrasound range of frequencies. Between settling tanks, there is surface drain arranged of the whole water mass, besides thickness of drained water layer does not exceed 5 cm. At river bottom upstream receiving pipe, 30-50 m ahead, there is system installed for artificial aeration of water, and 20-30 m ahead of receiving pipe - radiator of sound range of frequencies. Water in river is additionally treated with hydroacoustic waves of ultrasound range of frequencies with amplitude of sound pressure with at least 105 Pa, and also electromagnetic waves of ultrasound range of frequencies. Additionally two facilities are used, one of which comprises transparent pipe with system of illumination by various colour, which is connected by its inlet to outlet of receiving pipe, at the same time inside transparent pipe there are at least three pairs of oppositely directed hydroacoustic radiators of ultrasound range of frequencies, which form standing hydroacoustic waves, and another facility used is transparent pipe with system of illumination by various colours.
EFFECT: invention makes it possible to provide for efficient treatment and disinfection of large mass of water at minimum financial costs.
