Abstract

Procedimento per la depurazione delle acque di rifiuto per mezzo di un impianto di depurazione che presenta due stadi di attivazione, una chiarificazione intermedia tra primo e secondo stadio di attivazione, una post-chiarificazione a valle del secondo stadio di attivazione e circuiti del fango. Il primo stadio di attivazione viene attivato come stadio di adsorbimento con un carico di fango di almeno 2 kg BOD5 per chilogrammo di sostanza secca e al giorno, aerobicamente o, facoltativamente, anaerobicamente con principalmente procarionti nella biomassa attiva. Il secondo stadio di attivazione viene attivato come stadio aerato con un carico di fango inferiore a 0,15 kg BOD5 per chilogrammo di sostanza secca e al giorno. Il fango proveniente dalla post-chiarificazione viene convogliato di nuovo, almeno parzialmente, allo stadio di adsorbimento.
