Abstract
La presente invenzione riguarda un metodo per la depurazione di liquami contenenti formaldeide o fenolo oppure una miscela delle due sostanze, mediante ossidazione biologica.Il processo di ossidazione biologica oggetto di questa invenzione viene operato da una muffa isolata, dall'inventore, da un deposito di fibra di legno trattata con resina urea-formaldeide.Rif. Figure 2 e 3.
