Descripción

A method for biological treatment of waste water in reservoirs connected by pipings, one of such reservoirs is aerotank containing active silt where the process of aerobic oxidation of contaminated water is carried out followed by its precipitation. After precipitation, preliminary purified waste water is supplied to a reservoir containing macrophytes and to a ballast reservoir, after that the ballast reservoir is loaded with youth of double-wing mollusc -Dreissena which is attached to artificial substrate surface, followed by performing of closed water supply between the reservoir containing macrophytes and the ballast reservoir, and after termination of water supply from the aerotank an excessive increased pressure of 20,0?26,7 kPa is formed in aerotanks by air oxygen, and sunken higher water flora, and Zannichelliapalustris L. is used as macrophytes landed in reservoirs in layers.
