Abstract
Pojava povećanih koncentracija hranjivih tvari u površinskim vodama, prije svega dušikovih i fosfatnih spojeva, jedan je od najznačajnijih ekoloških problema današnjice, jer prisutnost navedenih nutrijenata u površinskim vodama šteti vodnim ekosustavima, uzrokujući smanjenje koncentracije otopljenog kisika i eutrofikaciju. Eutrofikacija je proces smanjenja kakvoće vodnog tijela koje se očituje prekomjernom rastu algi, povećanju koncentracije fitoplanktona te bujanjem biomase što za posljedicu može imati isušivanje vodnog tijela. Nekoliko tehnologija može učinkovito uklanjati hranjive sastojka iz otpadnih voda. U ovom radu ispitana je mogućnost uklanjanja dušika iz otpadne vode norveškog grada Trondheima pomoću tzv. Moving Bed Biofilm Reactor (MBBR) tehnologije. MBBR je nova, ekološki prihvatljiva i učinkovita tehnologija biološke obrade otpadnih voda usmjerena k uklanjanju hranjivih tvari iz otpadnih voda. Učinkovitost procesa i kinetika uklanjanja dušika određena je svakodnevnim praćenjem koncentracije otopljenog kisika, temperature, pH, kemijske potrošnje kisika te koncentracije dušika u različitim uvjetima.
Abstract (english)
The occurrence of elevated nutrient concentrations in surface waters, mainly nitrogen and phosphorous, has become one of the main global concerns since their presence in surface waters harm to the aquatic habitats and ecosystems causing the depletion of dissolved oxygen and eutrophication. Eutrophication is the process of impairing water quality manifested by excessive growth of algae, an increase of phytoplankton, and large production of biomass in the aquatic system. Therefore, nutrients removal is one of the main issues in wastewater treatment technologies nowadays. Several technologies can be used for nutrients removal from wastewater. In this thesis, nitrogen removal from wastewater of the city of Trondheim, Norway, was examined by the Moving Bed Biofilm Reactor (MBBR). The MBBR is a new biological wastewater treatment technology focused on nutrients removal from wastewaters. It is an ecologically acceptable and efficient process with reduced needs for space. The efficiency of the process and kinetics of nitrogen removal was determined by daily monitoring of dissolved oxygen, temperature, pH, chemical oxygen demand, and nitrogen concentrations under various conditions.
