An effluent treatment process and plant. The treatment includes at least one passage of the effluents through a device for biological pretreatment of the effluents, such as a bacterial bed, a lagoon or lagooning or a biological disc, at least one nitrification-denitrification of the pretreated effluents resulting from the biological pretreatment device, using a vertical-flow filter planted with rhizome plants, for example reeds, of which a lower zone is flooded and an upper zone is unflooded, and a device for injecting coagulants capable of precipitating the phosphates of effluents, for example ferric chloride salts. |
