| Learning verification modality | La verifica degli obiettivi formativi (esame) prevede una prova per ciascuno dei due moduli dell’’insegnamento (Ingegneria Sanitaria Ambientale e Impianti tecnici per il Trattamento dei Rifiuti). Per entrambe i moduli la prova consiste in una prova scritta ed in due prove orali. La prova scritta, per esigenze logistiche, potrà essere svolta in modo separato rispetto alle prove orali. La prova scritta, della durata di circa 30 minuti, prevede 10 quesiti a risposta multipla riguardanti i principi e le tecniche della depurazione delle acque reflue e i principi e le tecniche per la stabilizzazione dei rifiuti solidi. La prova ha lo scopo di verificare la capacità di comprensione delle problematiche proposte durante il corso e la capacità di applicare correttamente le conoscenze teoriche acquisite. La prima prova orale, della durata di circa 15 minuti, consiste nella discussione dei casi di studio sviluppati durante il corso. La seconda prova orale, della durata di circa 30 minuti, consiste in una discussione finalizzata ad accertare: - la conoscenza dei contenuti teorico-metodologici del corso - la conoscenza dei modelli adottati per simulare i diversi processi fisico-chimici su cui è basata la depurazione delle acque e dei rifiuti solidi; - la conoscenza di soluzioni impiantistiche per la rimozione degli inquinanti dalle acque reflue, per la stabilizzazione dei fanghi di risulta e per lo smaltimento dei rifiuti solidi; - la competenza nelle procedure computazionali proposte per il dimensionamento dei impianti di trattamento delle acque reflue e per lo smaltimento dei rifiuti solidi con particolare riguardo ai casi di studio sviluppati durante il corso; - l’autonomia di giudizio nel valutare le diverse strategie progettuali. Le prove orali hanno anche l’obiettivo di verificare la capacità dello studente di esporre con proprietà di linguaggio i temi proposti dalla Commissione, di sostenere un rapporto dialettico durante discussione e di riassumere i risultati applicativi delle procedure di calcolo studiate. La valutazione finale verrà effettuata dalla Commissione in trentesimi mediando i risultati di ciascuna prova con i seguenti pesi: Modulo “Ingegneria Sanitaria Ambientale” peso = 4/21; Modulo “Impianti Tecnici per il Trattamento dei rifiuti” peso = 1/7. |
