Monitoring of wastewater treatment plant of small town Labin

U ovom diplomskom radu motren je rad sustava za biološku obradu otpadnih voda grada Labina. Dan je kritički osvrt na učinkovitost provedbe obrade otpadne vode motrenjem pokazatelja kakvoće rada sustava i uspoređujući ih sa rezultatima navedenim u literaturi koji obrađuju otpadne vode istog podrijetla. Istaknuta je potreba za motrenjem i održavanjem čimbenika provedbe procesa (koncentracija otopljenog kisika, hranjivo, omjer C:N, temperatura) a koji su nužni za odvijanje bioloških procesa. Također, istaknuta je važnost motrenja mikrobiološke kakvoće aktivnog mulja (mikroskopski izgled, taloživost, aktivnost za biološke procese). Uređaj za obradu otpadnih voda grada Labina svojim tehnološkim rješenjem do danas osigurava visok stupanj pročišćavanja otpadnih voda a time i zaštitu potoka Krapanj kao prijemnika i konačno rijeke Raše u koju se ulijeva potok Krapanj.In this work the functioning of wastewater treatment plant of small town Labin was monitored. The critical overview on efficiency of wastewater treatment process evaluated by monitored process parameters and comparing it with results given in the literature for wastewater the some origin was given. It was emphasized the need for monitoring and maintaining of process parameters (dissolved oxygen concentration, C:N ratio, temperature) in order to carrying out biological processes. Also, the importance of monitoring microbiological quality of activated sludge (microscopic observation, sedimentation, activity for biological processes) was pointed out. Wastewater treatment plant of town of Labin along with its technological construction till the day shows high wastewater treatment efficiency and by that also the protection of Krapanj stream as a primary water receiver and the Raša river as the terminal water receiver in witch Krapanj stream inflow
