Abstract
Posljednjih godina, mnogobrojna znanstvena istraživanja ispituju mogućnost izdvajanja hranjivih tvari iz otpadnih voda u cilju njihove uporabe te smanjenja visokih koncentracija hranjivih tvari u pročišćenoj vodi, poput fosfora i dušika, jer pospješuju pojavu eutrofikacije i štetno utječu na vodne cjeline. Rezultati navedenih istraživanja također pokazuju da hranjive tvari izdvojene biološkim postupkom iz otpadnih voda imaju bolja svojstva biosorpcije u okolišu. Cilj ovog rada je ispitati učinkovitost uklanjanja fosfora iz otpadne vode grada Trondheima primjenom tehnologije bioreaktora s pokretnim filmom (Moving Bed Biofilm Reactor, MBBR) i tehnologijom naprednog biološkog uklanjanja fosfora (EBPR). Svakodnevne analize kakvoće ulazne otpadne vode (koncentracije otopljenog kisika i fosfora, temperatura, pH, KPK) omogućile su određivanje učinkovitosti i kinetike EBPR procesa. Uklanjanje fosfora iz otpadne vode ispitano je u šaržnom bioreaktoru u ovisnosti o koncentraciji otopljenog kisika i aktivnost bakterija u specifičnim radnim uvjetima. Rezultati su pokazali da je za učinkovito uklanjanje fosfora iz otpadne vode MBBR i EBPR procesom najznačajnija aktivnost fosfor akumulirajućih mikroorganizama (PAO). Također su utvrđeni i odnosi između kakvoće ulazne otpadne vode i procesnih parametara obrade otpadnih voda pri biološkom uklanjanju fosfora iz otpadne vode grada Trondheima.
Abstract (english)
Over the past years the process of the biological removal of nutrients in the wastewater treatment has become more and more scrutinizied in the world. The nutrients like phosphorus and nitrogen cause eutrophication and, consequently, have a detrimental effect on the environment. So, in this thesis the processes of the biological removal of phosphorus in a Moving Bed Biofilm Reactor (MBBR) and the Enhanced Biological Phosphorus Removal (EBPR) were examined. Also, the concentration of dissolved oxygen, temperature, pH, COD and phosphorus in typical Norwegian wastewater obtained from sewage system of city of Trondheim were measured on a daily basis. Moreover, the kinetics of phosphorus removal process was performed in several experiments using a batch bioreactor and the optimal concentration of dissolved oxygen and the activity of bacteria under specific operating conditions were investigated. The results shown that the Polyphosphate-Accumulating Organisms (PAOs) play a major role in the biological removal of phosphorus. The relations among wastewater quality (influent) and the wastewater treatment process parameters on phosphorus biological removal were also determined.
