Abstract
Uloga pročišćivaća voda ima veliki značaj od samih početaka civilizacije. Kao negativan produkt pročišćavanja voda je mulj, a njegov sastav uvelike ovisi o vrsti vode koja se pročišćava. Odgovarajućom obradom i postupcima uklanjanja svih opasnih čimbenika iz mulja, od kojih pojedini mogu biti vrlo skupi,dobiva se mulj koji se dalje može koristiti za razne svrhe. U ovom radu je opisan postupak obrade otpadnih voda te pojedine faze pročišćavanja u kojima nastaju muljevi. Nastali muljevi mogu sadržavati različite opasne tvari (teške metale, patogene mikroorganizme) što ga može svrstati u opasan otpad te je zbog toga potrebna njegova prethodna obrada. Metode obrade mulja su kondicioniranje, zgušnjavanje, stabilizacija, odvodnja, toplinska obrada, kompostiranje i anaerobna digestija. Iskorištavanje mulja nakon obrade će ovisiti o njegovom fizikalnom i kemijskom sastavu te je stoga vrlo važno pratiti kakvoću mulja. Ovisno o svojstvima mulj se može koristiti u energetske svrhe, poljoprivredi, građevini te na razne druge načine ili se mora zbrinuti na odgovarajući način.
Abstract (english)
The role of waste water treatment plant has been significant since the very beginnings of civilization. As a negative product of water treatment is sludge, and its composition depends largely on the type of water being treated. By appropriate sludge processing and removal of all hazardous factors, what can be very expensive, sludge can be used for various purposes. This paper describes the process of waste water treatment and some purification stages in which sludge is produced. The sludge produced may contain various dangerous substances (heavy metals, pathogenic microorganisms) which classify the sludge as a hazardous waste and therefore requires prior treatment. Sludge treatment methods include conditioning, condensation, stabilization, drainage, heat treatment, composting and anaerobic digestion. Usage of sludge after processing will depend on its physical and chemical composition and therefore it is very important to monitor the quality of the sludge. Depending on the properties, sludge can be used for energy purposes, agriculture, construction, etc. or it must be handled appropriately.
