Abstract:Namen diplomskega dela je ugotoviti učinkovitost biološke denitrifikacije v pitni vodi s pomočjo alge Chlorella sorokiniana v šaržnem reaktorju. Uporabljali smo pitno vodo iz Vodooskrbnega območja Ptuj s povprečno vsebnostjo nitratnih ionov 47 mg/L in vsebnostjo nitritnih ionov <0,05 mg/L. Aktivnemu blatu smo dodajali saharozo v razmerju C:N = 2,5:1 in je služila kot vir ogljika. V reaktorju smo zagotavljali anoksične pogoje. Ugotavljali smo ali prisotnost Chlorelle sorokiniane ugodno vpliva na denitrifikacijo v pitni vodi. Na začetku in na koncu reakcije smo merili fizikalno-kemijske parametre. Pri določenih vzorcih nas je zanimala kinetika reakcije. Ugotovili smo, da prisotnost alge Chlorelle sorokiniane v šaržnem reaktorju ne izboljša učinkovitosti biološke denitrifikacije, saj v primerjavi s samo aktivnim blatom v reaktorju dobimo slabše rezultate in za enako količino odstranjenega nitrata potrebujemo več časa. Hitrost denitrifikacije se torej v prisotnosti alg zniža.

Title:THE FEASIBILITY STUDY OF ALGAE USAGE FOR BATCH BIOLOGICAL WATER TREATMENT
Abstract:The aim of this diploma paper is to test the affectability of biological denitrification of the drinking water with the use of the Chlorella sorokiniana algae in the batch reactor. We used the water from Vodooskrbno območje Ptuj (Water supplying area Ptuj) with the average containment of nitrate ions 47 mg/L and with the containment of nitrite ions <0,05 mg/L. The sucrose was added to the activated sludge in the ratio C:N = 2,5:1 and served as the source of carbon. We guaranteed the anoxic conditions in the reactor. We were to establish if the presence of Chlorella sorokiniana affects positively on the removal of nitrogen compounds in the drinking water. At the inlet and outlet flow of the reactor, we measured physical-chemical parameters. Kinetics was studied using certain water samples. We discovered that the presence of the Chlorella sorokiniana algae in the batch reactor does not improve the affectability of the biological denitrification as we get worse results comparing to activated sludge alone and we need more time to remove the same amount of removed nitrate, therefore, the denitrification rate was worse if the algae were present.
