Abstract:Namen diplomskega dela je bil preučiti učinkovitost denitrifikacije na čistilni napravi Odranci. Občina Odranci s približno 1.650 prebivalci ima zgrajeno kanalizacijsko omrežje, ki je v celoti priključeno na komunalno čistilno napravo. Čistilna naprava Odranci je sedaj zaradi svoje zmogljivosti čiščenja 1.950 populacijskih ekvivalentov – PE, klasificirana kot mala komunalna čistilna naprava. Po načrtovani posodobitvi bo zaradi povečane kapacitete čiščenja na 2.450 PE, uvrščena med komunalne čistilne naprave – KČN. Ker so rezultati monitoringov iz prejšnjih let pokazali večinoma povečane mejne vrednosti amonijevega dušika ob iztoku, smo v teku diplomskega dela ugotavljali vzroke. Izvajali smo meritve parametrov: motnosti, neraztopljenih snovi, usedljivih snovi, kemijske potrebe po kisiku, biokemijske potrebe po kisiku, amonijevega dušika in pH, s katerimi smo pridobili podatke o dnevnem nihanju čistilne naprave. Meritve smo izvajali na vtoku in iztoku iz čistilne naprave, kjer se tudi običajno izvajajo. Dodatno smo preučili še, kaj se dogaja z odpadno vodo v cevi od iztoka iz čistilne naprave do njenega izliva v potok Črnec. Potrdili smo, da je potrebno rešiti problematiko meteornih vod. Rezultati kažejo, da je mejna vrednost amonijevega dušika presežena, kar kaže da procesa nitrifikacije ter denitrifikacije ne potekata pravilno in bi bilo zato potrebno preveriti tudi določene lastnosti in učinkovitost obratovanja biorotorjev.

Title:The study of the efficiency of denitrification of wastewater treatment plants Odranci
Abstract:The purpose of the thesis was to study the efficiency of denitrification on the wastewater treatment plant Odranci. The municipality of Odranci with a population of approximately 1650 has constructed a sewer network, which is connected to the communal wastewater treatment plant in its entirety. The wastewater treatment plant Odranci is now, due to its capacity of processing 1950 population equivalents - PE, classified as a small communal wastewater treatment plant, but after the planned upgrade, due to its processing capacity increasing to 2450 PE, it will be listed among communal wastewater treatment plants – CWTP. Since results of monitoring from past years have shown mostly an increase in marginal values of ammonia nitrogen at the outflow, we, through this diploma thesis, attempted to find the reasons. We carried out parameter measurements: turbidity, suspended solids, settleable solids, chemical oxygen demand, biochemical oxygen demand, ammonia nitrogen and pH, through which we obtained data on the daily fluctuation of the wastewater treatment plant. We carried out the measurements at the inflow and the outflow from the plant, where they are usually carried out, but additionally studied, what happens to the wastewater in the pipe from the outflow of the purification plant to its entry into the Črnec stream. We confirmed, that the rainwater problems have to be solved. Results show, that the marginal value of ammonia nitrogen is exceeded, which shows that the process of nitrifiltration and denitrification are not taking place correctly and thus call for a verification of certain characteristics and operating efficiency of the biorotors.
Keywords:wastewater treatment plant, ammonia nitrogen, denitrification, reconstruction, rotating biological contactors
