Abstract

U ovom diplomskom radu dan je kritički osvrt na učinkovitost rada uređaja za pročišćavanje otpadnih voda Čakovec motrenjem pokazatelja kakvoće rada sustava i uspoređujući ih sa maksimalnim dopuštenim koncentracijama određivanih pokazatelja određenih Zakonom. Istaknuta je dobra mikrobiološka aktivnost aktivnog mulja. Tijekom motrenog perioda travanj – rujan 2007. godine postignuto je uklanjanje organskih sastojaka izraženih kao KPK vrijednost i BPK5-vrijednost više od 90 %, sastojaka s dušikom i to ukupni dušik 76 – 97 % i amonijakalni dušik 91 – 99 % bez nakupljanja nitrata. Uređaj za obradu otpadnih voda grada Čakovca svojim tehnološkim rješenjem do danas osigurava visok stupanj pročišćavanja otpadnih voda a time i zaštitu rijeke Trnave kao konačnog prijemnika.

Abstract (english)

In this work process analysis of wastewater treatment plant of Čakovec city was given. The process was monitored by measurement of process parameters and comparing them with the maximum allowed concentration regulated by the national law. It was emphasized a good microbial activity of activated sludge. During monitored period from April to September 2007. the following average removal efficiencies were determined: for chemical oxygen demand (COD) and biochemical oxygen demand (BOD) more that 90%, for nitrogen compounds as total nitrogen 76-97% and for ammonium nitrogen (N-NH4) 91-99% without nitrate accumulation. By existing technology wastewater treatment plant of Čakovec city ensures high efficiency of wastewater treatment and by that protection of river Trnava as a final water receiver.
