Abstract
Predmet ovog rada je uređaj za pročišćavanje otpadnih voda trećeg stupnja pročišćavanja, kapaciteta 1335 ES za aglomeraciju Vojnić. Na razini idejnog projekta obrađena su tehnološka rješenja i izrađeni hidraulički proračuni za linije vode i linije mulja. Liniju vode čine mehanički predtretman i biološki tretman sa KPAM tehnologijom (koncencionalni postupak s aktivnim muljem). Mehanički predtretman čine kanal s grubom rešetkom, ulazna crpna stanica, koja sirove otpadne vode podiže do fine rešetke i aeiranog pjeskolova-mastolovoma. Biološki tretman otpadnih voda se provodi u biološkom reaktoru (preanoksična denitrifikacija) i naknadnom taložniku s crpnom stanicom za povratni tok mulja. Iz biološkog reaktora se pročišćene otpadne vode gravitacijski ispuštaju u recipijent. Fosfor se uklanja isključivo kemijskim obaranjem. Linija mulja, nastalog nakon biološkog tretmana iz KPAM postupka započinje odvođenjem izdvojenog mulja na gravitacijsko zgušnjavanje, nakon kojeg slijedi njegovo privremeno retenciranje u odvojenom spremniku (do max. 5 dana).
Abstract (english)
The subject of this thesis is WWTP with the third stage of treatment, and with a capacity of 1335 PE for the Vojnic agglomeration. At the level of the preliminary design, technological solutions were designed and hydraulic calculations for water lines and sludge lines were made. The water line consists of mechanical pretreatment and biological treatment with CAS technology (conventional process with activated sludge). Mechanical pretreatment consists of a channel with a coarse screen, an inlet pumping station, fine screens and aerated grit and grease chamber. Biological treatment of wastewater is carried out in a biological reactor (pre-anoxic denitrification) and a subsequent clarifier with a pumping station for the return flow of sludge. Treated wastewater from the biological reactor is discharged by gravity into the recipient. Phosphorus is removed exclusively by chemical precipitation. The line of sludge, created after biological treatment from the CAS procedure, begins with the removal of the separated sludge for gravity thickening, followed by its temporary retention in a separate tank (up to max. 5 days).
