Abstract
Procedeu de epurare biologica a apelor reziduale cu continut de benzendisulfonati de sodiu si de calciu, difenoli si rezorcinat de sodiu, caracterizat prin aceea ca, în scopul biodegradarii impurificatorilor din ape, cu randament de 90...95%, apele reziduale se aduc la pH = 7...8 se decanteaza, apoi se supun aerarii, introducînd namol biologic activat cu ioni de Mg la puterea 2+ si Mn la 2+.A process for the biological treatment of waste water containing sodium and calcium benzodisulfonates, diphenols and sodium resorcinate, characterized in that, in order to biodegrade the water impurities in a yield of 90 ... 95%, the waste water is brought to pH = 7 ... 8 is decanted, then subjected to aeration, introducing biologically activated sludge with Mg ions to 2+ and Mn to 2+.
