Abstract

Mikrobna populacija aktivnog mulja otpadnih voda je kompleksan mikrobni ekosustav. Stoga je cilj rada odrediti sastav mikrobne populacije u uzorcima aktivnog mulja iz otpadne vode vinarije iz Istre. Rezultati istraživanja dobiveni su mikrobiološkom analizom aktivnog mulja iz otpadne vode vinarije tijekom 3 mjeseca. Analize su provođene u više intervala ovisno o tome kako su uzorci pristizali na analizu. Izvršena je analiza 12 pristiglih uzoraka u rasponu od 87 dana. U svim uzorcima aktivnog mulja izolirani su mikroorganizmi karakteristični za otpadne vode i to: protozoe, nematode, bakterije te kvasci, a uzevši u obzir da se radi o prihvatnom tanku vinarije u koji se osim otpadne vode iz proizvodnog pogona vinarije ulijevaju i kanalizacijski ispusti, bilo je za očekivati prisutnost koliformnih bakterija, što je analizama i potvrđeno.

Abstract (english)

A microbial population in the activated sludge from wastewaters is a complex microbial ecosystem. Therefore, the goal of this work was to determine the composition of the microbial population in the samples of wastewater from the winery in Istria. The results were obtained based on the measurements performed in a 3-month period. Analyses were conducted in several time intervals, depending on how the samples had arrived for analysis. There were 12 samples over the course of 87 days. All samples of activated sludge contained the characteristic organisms: protozoa, nematodes, bacteria, and yeasts. Considering the samples were taken from a tank that also takes in sewage, the presence of coliform bacteria was expected, which was confirmed by analyses.
