Abstract
Invenţia se referă la un procedeu combinat de tratare a sedimentului, obţinut la fermentarea anaerobă a apelor reziduale şi poate fi utilizată în industriile vinicolă şi alimentară la tratarea şi utilizarea deşeurilor.Procedeul include utilizarea în calitate de coagulant a defecatului, care se formează la tratarea extractelor zaharoase cu var, în cantitate de 50...100% de la masa sedimentului uscat, cu aducerea amestecului obţinut până la un pH 7,5…8,5, agitarea timp de 30…60 min, sedimentarea timp de 1…2 ore, cu decantarea ulterioară, apoi sedimentul se tratează cu un floculant, şi anume cu soluţie de poliacrilamidă de 0,2…0,5% în cantitate de 50...100 mg/dm3 prin introducerea ei treptată de 2…3 ori, în cantitate de (0,50...0,60):(0,20...0,50):(0,20...0,25) corespunzător, după care lichidul se elimină şi sedimentul se deshidratează prin compresie.
