Sažetak
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.
