Optimizacije delovanja biološkega dela Centralne čistilne naprave Nova Gorica : magistrsko delo

Lestan, Timotej (author), Drev, Darko (mentor)

Osrednja tema magistrske naloge je pregled in preračun možnosti optimizacije delovanja biološkega dela Centralne čistilne naprave Nova Gorica. V prvem delu naloge so predstavljena pomembnejša zakonodajna in teoretična izhodišča čiščenja odpadnih voda na čistilnih napravah. V drugem delu magistrska naloga predstavi rezultate eksperimentalnega dela, v sklopu katerih se je v laboratoriju analiziral odvzet vzorec odpadne vode iz čistilne naprave. Rezultate se je kasneje upoštevalo v eni izmed variant možnosti optimizacije delovanja čistilne naprave. Predstavljen je tudi uporabljen računalniški program, prav tako pa so podani vhodni podatki in predpostavke pri računskih postopkih. Za obravnavane obremenitvene variante ter dodatno varianto z upoštevanjem nadaljnje obdelave blata so se izračunali mogoči optimalni pogoji delovanja biološkega dela čistilne naprave pri danih vhodnih podatkih in predpostavkah. Ugotovilo se je, da pod določenimi pogoji biološki del čistilne naprave lahko deluje brez stroškov. Na koncu naloge je predstavljena primerjava rezultatov obravnavanih obremenitvenih variant.

• Title: Optimisation of Operational Condition of Biological Treatment of Wastewater Plant Nova Gorica : master thesis

Abstract

Thesis describes the review and optimization possibilities of wastewater treatment of central wastewater plant Nova Gorica. In the first part regulations and the theoretical background of biological wastewater treatment are presented. Which is followed by results of experiment done in laboratory. In the laboratory wastewater samples from abovementioned plant were analysed. The results were later used as input calculation data. The AquaDesigner software was used for calculation for the optimum operational conditions. Based on input data and prepositions calculation for all different variants including variant with additional waste sludge treatment were made. The conclusion was made that under given prepositions biological treatment of wastewater plant could operate at zero cost. At the end a comparison between the calculated variants were presented.
