Abstract
Invenţia se referă la procedeele biochimice combinate de epurare a apelor uzate de poluanţi organici şi poate fi aplicată la staţiile de epurare în industriile vinicolă şi alimentară.Procedeul include concentrarea apelor uzate prin ultrafiltrarea componentelor organice macromoleculare până la valoarea CCO de 20000…40000 mg/dm3, cu separarea filtratului având valoarea CCO de 100…300 mg/dm3 , fermentarea anaerobă a concentratului, utilizând microfloră fixată, cu formarea biogazului, totodată pentru fixarea microflorei se utilizează corzi de viţă de vie cu diametrul de 2…3 mm şi densitatea de împachetare de 3…5 kg/dm2, după care se efectuează epurarea aerobă a concentratului fermentat şi a filtratului.Pe lângă aceasta concentrarea apelor uzate se efectuează cu utilizarea ultrafiltrelor tubulare la presiunea de 3…5 atm şi viteza de curgere a apei de 5…10 m/s.Rezultatul invenţiei constă în reducerea consumului de energie şi ieftinirea procesului de epurare.
