Abstract

Završni rad obrađuje temu mehaničkog predtretmana kao neizostavnog dijela svakog UPOV-a na teoretskoj razini. Povećanjem populacije i urbanizacijom, potrošnja vode i problematika njenog zagađenja su se značajno povećali. U svrhu pročišćavanja i ponovnog korištenja otpadnih voda koriste se uređaji za pročišćavanje otpadnih voda. Pritom, glavni je osvrt na tri ključna elementa koji se u okviru svjetske i hrvatske prakse najčešće koriste – grube rešetke, fine rešetke i aerirani pjeskolov mastolov. Svrha glavnih elemenata jest uklanjanje velikih krutina te uklanjanje pijeska i masnoća. Uz to, obrađena je i tema karakteristika otpadnih voda kao ulazni podatak koji prethodi samim tehnološkim postupcima mehaničkog predtretmana u sklopu sustava javne odvodnje.

Abstract (english)

The final paper addresses the topic of mechanical pretreatment as an indispensable part of every wastewater treatment plant (WWTP) on a theoretical level. With the increase in population and urbanization, water consumption and the issue of its pollution have significantly risen. For the purpose of purifying and reusing wastewater, wastewater treatment devices are used. The focus is mainly on three key elements that are most commonly used in global and Croatian practice – rough grids, fine grids, and aerated grit and grease traps. The purpose of these main elements is to remove large solids and eliminate sand and grease. Additionally, the characteristics of wastewater are discussed as an input data that precedes the technological processes of mechanical pretreatment within the public drainage system.
