Abstract
A process for treating effluents loaded with organic material, particularly wine-making effluents essential in the form of wash water, comprises pouring the effluents to be treated into a storage basin (1) and actuating a recirculation circuit (2) between this latter and an oxygenation reactor (3) for the effluents, actuating a superoxygenation device (4) when the volume of effluents stored is too great to avoid passing into anaerobic phase, then stopping the superoxygenation and maintaining the recirculation at a minimum level avoiding the passage into anoxia of the effluents, when these latter fulfill certain minimum pollution conditions. The effluents are poured over at least one purification body (5) and the purified effluents are withdrawn, until there is substantially nothing left but residual decantation sludges more or less mineralized, in the storage basin (1). These latter are treated to delay the organic components present and to lead to a substantially inert mineralized sludge.
