Abstract

Termalna hidroliza (THP proces) predstavlja međufazu obrade mulja na uređajima za pročišćavanje otpadnih voda(UPOV-ima). Njegovom upotrebom se postiže smanjenje ukupnih količina mulja, povećanje stupnja energetskog iskorištavanja mulja i dobivanje mulja boljih karakteristika za njegovo daljnje zbrinjavanje. THP proces se može primijeniti na 2 osnovna načina-prvi je ispred anaerobnih digestora( prednost kod novo projektiranih i postojećih UPOV-a na kojima se planira povećanje kapaciteta linije mulja), a drugi je nakon anaerobnih digestora(prednost kod postojećih i kod UPOV-a gdje se ne planira povećanje kapaciteta linije mulja). Ovaj rad daje opis metodologije i rezultata primjene THP procesa na postojećim i novim UPOV-ima. Detaljnije je objašnjeno kroz tehničku i financijsku analizu na primjeru UPOV Rijeke. Analize ukazuju na ekonomsku isplativost uvođenja THP procesa uz sagledavanje ključnih faktora poput troškova uvođenja procesa (izgradnja, te pogon i održavanje), energetske iskoristivosti i konačnog zbrinjavanja mulja.

Abstract (english)

Thermal hydrolysis(THP process) is the inter-phase treatment of sludge at wastewater Treatment plants(WWTPs). It's use has resulted in a reduction in the total amount of sludge, an increase in the degree of energy use of sludge and a better sludge yield for further disposal. THP process can be applied in 2 basic ways-first is in front of anaerobic digestors( advantage for newly and already existing WWTPs where sludge is planned to be increased) and the second is after anaerobic digester(preference for existing nad WWTPs where no sludge line is planned to be increased). This paper describes the methodologies and results of applying the THP process to existing and new WWTPs. It's explained through technical and financial analysis on the example of WWTPs Rijeka. Analysis point to the cost-effectiveness of introducing a THP process with consideration of key factors such as the cost of the process installment (construction, operation and maintenance) ,energy efficiency and final disposal of sludge.
