Abstract

Namen magistrskega dela je bil določitev vsebnosti trdnih delcev v odpadni komunalni vodi med postopki čiščenja na čistilni napravi. Želeli smo primerjati vsebnosti suspendiranih in raztopljenih delcev v komunalni odpadni vodi na vtoku na čistilno napravo, po primarnem čiščenju in iztoku ter rezultate primerjati z rezultati po obdelavi z membranskim bioreaktorjem (MBR). Izmerili smo naslednje fizikalno-kemijske parametre: pH, motnost, prevodnost, barva, vsebnost trdnih delcev in vsebnost organskih snovi, izraženih kot KPK. Glede na rezultate fizikalno-kemijskih parametrov smo ugotovili, da se vrednosti motnosti, barve, vsebnosti vseh snovi (TS) in KPK s čiščenjem znižujejo v skladu s pričakovanji. Analiza vsebnosti trdnih delcev je pokazala, da so izračunane vrednosti v vzorcih odpadnih vod po predčiščenju, kjer je prisotnih 70 % raztopljenih in 30 % suspendiranih snovi, v skladu z literaturnimi navedbami. Po biološkem čiščenju je okoli 90 % raztopljenih in 10 % suspendiranih snovi, medtem ko so se slednje po čiščenju z MBR popolnoma odstranile. Raziskava je pokazala, da je korelacija med vsebnostjo skupnih suspendiranih snovi in KPK relativno nizka v vseh fazah čiščenja odpadne vode.

Secondary title:	THE CONTENT OF SOLID PARTICLES DURING SECONDARY TREATMENT OF WASTEWATER
Secondary abstract:	The aim of this master's work is to determine the content of solid particles in the process of purification of municipal wastewater in the water treatment plant. We wanted to compare the content of suspended and dissolved solids in municipal wastewater in the influent of the wastewater treatment plant, after the primary treatment and in the effluent. The results were compared with the results after the treatment in the membrane bioreactor (MBR). We measured the following physico-chemical parameters: pH, turbidity, conductivity, color, and the content of organic substances, expressed as COD. Based on the results of the physico-chemical parameters, we find out that, as expected, the opacity values, color, content of all the substances (TS), and the COD reduce during water treatment. An analysis of the solids particles content showed that the calculated values of the samples of wastewater after the primary treatemnt, where there is presence of 70% of soluble and 30% of suspended solids, were in line with the literature references. After the biological treatment there is about a 90% of soluble and 10% of suspended solids, while the latter, after the purification by MBR are completely removed. The study showed that a correlation between the content of total suspended solids and the COD is relatively low at all stages of the waste water treatment.
