Abstract:Blato, ki je nastaja na čistilnih napravah odpadnih voda, je precejšn problem. Ustrezno ravnanje z odpadno vodo je prioriteta pri upravljanju z vodami. Ne glede na to, v kolikšni meri se čistijo odpadne vode, te tvorijo določeno količino blata (0,5 kg blata/m³ odpadne vode) – pojavlja se torej kot stranski produkt, ki ga je treba odstraniti v skladu z zakonskimi predpisi. V pričujočem delu so podrobneje opisani možni zaključni postopki in odlaganje blata iz čistilne naprave za odpadne vode. V magistrskem delu smo se osredotočili na ponovno uporabo blata - za razvoj novih materialov, ki se lahko uporabljajo na področju kmetijstva kot gnojilo/ojačevalci humusa ali pa za toplotno obdelavo. Pred začetkom eksperimentalnega dela smo morali blato dehidrirati. Testiranje blata v laboratoriju za tvorbo potencialnega goriva je potekalo s kemijsko analizo, merjenjem vsebnosti vlage, določevanje kurilne vrednosti in klora.. V drugem poskusu smo na osnovi kalilnega in rastnega testa pridobili rezultate, ki kažejo, ali je blato primerno za uporabo v kmetijske namene.

Title:Advanced technologies for pre-treatment of sludge and development of new materials from the same
Abstract:Sludge, which is produced as a product on waste water treatment plants, is a major environmental problem the world. Adequate waste water treatment is a priority for water management. Regardless of the concept of wastewater treatment, a certain amount of sludge (0,5 kg of sludge / m³ of waste water) is produced as a by-product that needs to be disposed of in accordance with legal requirements. Possible procedures for the final treatment and disposal of sludge from the wastewater treatment plant are detailed in this document. In the graduation work we focused on the recycling of sludge, that is, on the development of new materials that will be applicable in the field of agriculture as fertilizer/humus enhancersand for thermal treatment. Before the very beginning of the experimental work, the sludge had to be dehydrated. The sludge testing in the laboratory for the development of a potential fuel consisted of a chemical analysis, a measurement of the moisture content, the determination of the heating value and chlorine. In the second experimental work on the basis of the growth and calorie test, we obtained results that show us whether the sludge is suitable for agricultural purposes.
