ID Slovša, Renata Janja (Author) Files: Renata_Janja_Slovsa.pdf (2,33 MB) MD5: CF8CE281F7353C2F1B5884157DDC47F2   Language: English Work type: Master's thesis/paper Typology: 2.09 - Master's Thesis Organization: FPŠ - Graduate School Abstract: The purpose of this master’s thesis is to present the operation of a large municipal waste water treatment plant in Slovenia with over 300.000 PE and its efficiency, and through a theoretical analysis to present the current practice and alternative options of sewage sludge treatment in Slovenia and around the globe. The main objective of master's thesis is to present the most possible alternative scenarios for the final managing of sewage sludge from WWTPs and at this objective we take into consideration the impact on Carbon Foot Print (CFP). Due to scenarios (thermal utilisation of dried sludge (90% d.m.) in a cement plant, co-incineration of dehydrated sludge (25% d.m.) in a local power plant, thermal utilisation of dried sludge (90% d.m.) in a local power plant, incineration of dehydrated sludge (25% d.m.) in own plant, incineration of dried sludge (90% d.m.) in own plant, and also prohibited scenarios such as sludge utilisation in the soil -fertilization, sludge disposal in the landfill) we calculated CFP and we find out that CFP of various methods of thermal sludge treatment are more or less similar but absolutely smaller than convetional sewage sludge treatment. The CFP is more favourable for dehydrated sludge than for pre-dried sludge, and it is also more favourable for treatment in industrial furnaces (heat power plant, cement plant) than in individual waste incineration facilities.

Title:	ANALIZA ALTERNATIVNIH MOŽNOSTI ZA OSKRBO ODPADNEGA BLATA Z NOVE CENTRALNE ČISTILNE NAPRAVE LJUBLJANA
Abstract:	The purpose of this master’s thesis is to present the operation of a large municipal waste water treatment plant in Slovenia with over 300.000 PE and its efficiency, and through a theoretical analysis to present the current practice and alternative options of sewage sludge treatment in Slovenia and around the globe. The main objective of master's thesis is to present the most possible alternative scenarios for the final managing of sewage sludge from WWTPs and at this objective we take into consideration the impact on Carbon Foot Print (CFP). Namen magistrskega dela je predstaviti delovanje velike KČN v Sloveniji s preko 300.000 PE, njeno učinkovitost in preko teoretične analize predstaviti dosedanjo prakso in alternativne možnosti za oskrbo odpadnega blata tako v svetu kot v Sloveniji. Glavni cilj magistrskega dela pa je predstaviti najbolj možne alternativne scenarije za končno upravljanje blata iz čistilnih naprav z upoštevanjem vpliva na ogljični odtis. Glede na obravnavane scenarije v magistrskem delu (termična uporaba posušenega blata (90% dm) v cementarni, sosežig dehidriranega blata (25% dm) v lokalni termo-elektrarni, termična uporaba posušenega blata (90% dm) v lokalni termo-elektrarni, sežig dehidriranega blata (25% dm) v lastnem obratu, sežig posušenega blata (90% dm) v lastnem obratu in prav tako prepovedane scenarije, kot so na primer uporaba blata kot gnojilo, odlaganja blata na deponije) smo izračunali ogljični odtis in ugotovili, da so rezultati ogljičnih odtisov različnih načinov termične obdelave blata bolj ali manj podobni, vendar absolutno manjši od konvencionalna obdelav blata iz čistilnih naprav. Ogljični odtis je ugodnejši za dehidrirana blata kot za predhodno posušena blata, prav tako pa je ugodnejši za obdelavo v industrijskih pečeh (termo- elektrarni, cementarni) kot pa za posamezne objekte za sežiganje odpadkov.
