Abstract

V uvodu diplomskega dela sem predstavila problematiko onesnaženja odpadnih voda kot posledico vse širše rasti populacije in gospodarstva. Opisane so osnove čiščenja odpadnih voda v komunalnih čistilnih napravah. Stranski produkt čiščenja odpadnih voda je odvečno odpadno blato, katerega količina se povečuje in postaja čedalje večji okoljski problem, predvsem v primeru visokih vsebnosti potencialno strupenih elementov. V diplomskem delu sem predstavila problematiko odpadnega blata v Sloveniji in zakonodajo Republike Slovenije na področju ravnanja z odpadnim blatom iz komunalnih čistilnih naprav. V nadaljevanju dela sem povzela že uveljavljene kemične, biološke in termične postopke odstranjevanja potencialno strupenih elementov v odpadnem blatu, kot tudi novejše, še ne tako uveljavljene in raziskane postopke. Rezultati raziskav nakazujejo, da ima največjo učinkovitost pri stabilizaciji in odstranjevanju potencialno strupenih elementov v odpadnih blatih predvsem kombinacija več metod, vendar so nadaljnje raziskave v smeri vključevanja novih metod in njihove optimizacija nujno potrebni.

Secondary title: Potentially toxic elements in sewage sludge from municipal wastewater treatment plants
Secondary abstract: The diploma thesis explains the problem of wastewater pollution as a result of the ever-expanding population and economic growth. It describes the basic wastewater treatment methods in municipal wastewater treatment plants, the by-product of which is also sewage sludge. The amount of excess sewage sludge is increasing and poses a serious threat to the environment, especially due to the high content of toxic elements. Therefore, the thesis outlines the posing issue of sewage sludge in Slovenia and the legislation of the Republic of Slovenia in the field of sewage sludge treatment from wastewater treatment plants. It includes a summary of established and novel chemical, biological and thermal methods for the elimination of toxic elements in sewage sludge. The research results indicate that the combination of several methods is most effective in stabilizing and removing potentially toxic elements in sewage sludge. Further research focusing on the inclusion of new methods and their optimization is absolutely necessary.
