Abstract

U ovom radu motrena je učinkovitost rada uređaja za pročišćavanje otpadne vode grada Čakovca. Uređaj je projektiran za biološko opterećenje 91000 ES (ekvivalent stanovnika). Svakodnevno su određivane vrijednosti KPK (kemijska potreba na kisiku), BPK5 (biološka potreba na kisiku), N-ukupni, P-ukupni, NH4-N, NO3-N, suspendirane tvari, koncentracija mikrobne biomase i pH-vrijednost. Dan je kritički osvrt na učinkovitost rada uređaja za pročišćavanje otpadnih voda motrenjem pokazatelja kakvoće rada sustava i uspoređujući ih sa maksimalnim dopuštenim koncentracijama određivanih pokazatelja određenih Zakonom. Postiže se obrada otpadnih voda do zahtijevane kakvoće, definirano zakonskim propisima. Obrađena voda može se ispuštati u prirodni prijemnik, rijeku Trnavu.

Abstract (english)

In this work the efficiency of the wastewater treatment plant of Čakovec city was monitored. The plant was designed for a biological load of 91000EP (equivalent population). Daily, in influent and effluent, the following parameters were determined: COD (chemical oxygen demand), BOD (biological oxygen demand), N-total, P-total, NH4-N, NO3-N, suspended solids, microbial biomass and pH. The biological treatment process was monitored by determined of process parameters and comparing them with the maximum allowed concentration regulated by the national law. The wastewater is treated to a desired quality regulated by the law. The treated wastewater can be discharged into the natural recipient, the Trnava river.
