Abstract

Predmet ovog rada je uređaj za pročišćavanje otpadnih voda trećeg stupnja pročišćavanja, kapaciteta 24.208 ES za aglomeraciju Petrinja. Na razini idejnog projekta obrađena su tehnološka rješenja i izrađeni hidraulički proračuni za linije vode i linije mulja. Liniju vode čine mehanički predtretman s prethodnim taložnikom i biološki tretman sa SBR tehnologijom. Mehanički predtretman čine kanal s grubom rešetkom, ulazna crpna stanica, koja sirove otpadne vode podiže do fine rešetke i aeiranog pjeskolova-mastolovoma, a zatim slijede prethodni taložnik i egalizacijski bazen. Biološki tretman otpadnih voda se provodi u SBR reaktorima, iz kojih se pročišćene otpadne vode gravitacijski ispuštaju u recipijent. Linija mulja, nastalog nakon biološkog tretmana iz SBR reaktora i prethodnog taložnika, započinje odvođenjem izdvojenog mulja na mehaničko zgušnjavanje, nakon kojeg slijedi aerobna stabilizacija, dehidracija i solarno sušenje.

Abstract (english)

The subject of this thesis is a wastewater treatment plant of the third stage of treatment, with a capacity of 24.208 ES for the Petrinja 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 with pre-settling and biological treatment with SBR technology. Mechanical pretreatment consists of a channel with a coarse screen, an inlet pumping station, which raises raw wastewater to fine screens and aerated grit and grease chamber, followed by a primary sedimentation tank and an egalization tank. Biological treatment is carried out in an SBR reactors, from which the treated water is discharged in the recipient. The sludge line, formed after biological treatment from the SBR reactor and primary sedimentation tank, begins with the leading of the separated sludge on mechanical thickening, followed by aerobic stabilization, dewatering and finally the solar drying units.
