Abstract

Uvodni del diplomske naloge predstavlja osnove čiščenja odpadnih voda in obdelave odvečnega blata komunalne čistilne naprave (KČN). V nadaljevanju je povzeta slovenska zakonodaja, ki narekuje prihodnjo rabo odvečnega blata na naših tleh. Sledi opis alternativnih možnosti ravnanj z odvečnimi blati KČN ter seznanitev z izvori onesnaženja odpadnih voda in načini, kako zmanjšati oziroma odstraniti polutante voda že na njihovem izvoru, z namenom sonaravnega urejanja odpadnih voda in blata. V praktičnem delu sem ugotavljala, v kakšnem stanju je odvečno blato Centralne čistilne naprave (CČN) Jesenice, kaj z njim naredijo po končani obdelavi in na podlagi pridobljenih rezultatov analiz blata preučila nadaljnje možnosti njegove uporabe. Blato iz CČN Jesenice je onesnaženo s težkimi kovinami (baker, živo srebro, nikelj, svinec), iz vzorca pa je bila izolirana tudi salmonela. Uporaba takšne vrste blata je zelo omejena, zato sem ugotavljala tudi vzroke prekomernega onesnaženja voda na območju Občine Jesenice, zaradi katerih je blato posledično oporečno, in podala predloge za njihovo zmanjšanje.

Secondary title: Possible uses of sewage sludge from the central wastewater treatment plant Jesenice
Secondary abstract: The introductory part of the diploma thesis describes the basics of wastewater and sewage sludge treatment in municipal wastewater treatment plants. The thesis then summarizes the Slovene legislation, which regulates the future usage of sewage sludge in Slovenia. Next, it outlines the alternatives to sewage sludge treatment in wastewater treatment plants and introduces the origins of sewage and the ways of how to reduce or even remove water pollutants at their sources. The practical part investigates the state of sewage sludge in the central wastewater treatment plant Jesenice and what happens to it after its treatment. On the basis of the sewage sludge analysis results, the thesis researches further options for its usage. The sewage sludge in the municipal wastewater treatment plant Jesenice is polluted with heavy metals (copper, mercury, nickel, lead) and a sample also contained Salmonella. The usage of such sewage sludge is very limited; that is why the thesis explores the reasons for inordinate water pollution in the Municipality of Jesenice, which leads to sewage sludge's contamination, and suggests proposition for its reduction.
