Abstract
Kako bi se očuvala kakvoća vodnog ekosustava, komunalne otpadne vode moraju zadovoljiti postavljene standarde o kakvoći otpadnih voda prije ispuštanja u prirodni prijemnik. S obzirom da komunalne otpadne vode uobičajeno uz sanitarne sadrže još i industrijske otpadne vode, u ovom radu primjenjen je proces elektrokoagulacije i obrade na prirodnom zeolitu (EKZ) kako bi se ispitala učinkovitost njene obrade. Eksperimenti su provedeni u šaržnom reaktoru s aluminijevim elektrodama. Ispitan je utjecaj početne pH vrijednosti, dodatak prirodnog zeolita i dodatak elektrolita NaCl na učinkovitost integriranog procesa. Parametri analizirani tijekom provedbe eksperimenta su: pH, električna provodnost, temperatura, mutnoća, kemijska potrošnja kisika (KPK), ukupni dušik po Kjeldahlu i test taloženja. Rezultati pokazuju da početna vrijednost pH uzorka, dodatak zeolita, kao i dodatak NaCl elektrolita imaju značajan utjecaj na smanjenje mutnoće, smanjenje ukupnog dušika po Kjeldahlu te na brzinu taloženja. Utjecaj na smanjenje KPK i električne provodnosti je manje izražen. Temeljem podataka o utrošku mase elektroda te napona i struje u procesu elektrokoagulacije, izračunati su operativni troškovi za sve eksperimentalne uvjete.
Abstract (english)
In order to preserve the quality of the water ecosystem, municipal wastewater must meet the set standards for the quality of waste water before being discharged into a natural recipient. Given that municipal wastewater usually contains industrial waste water in addition to sanitary water, in this work the process of electrocoagulation and treatment on natural zeolite (ECZ) was applied in order to test the efficiency of its treatment. The experiments were carried out in a batch reactor with aluminium electrodes. The influence of the initial pH value, the addition of natural zeolite and the addition of NaCl electrolyte on the efficiency of the integrated process was examined. The parameters analysed during the experiment are: pH, electrical conductivity, temperature, turbidity, chemical oxygen consumption (COD) and total Kjeldahl. The results show that the initial pH value of the sample, the addition of zeolite, as well as the addition of NaCl electrolyte have a significant impact on the reduction of turbidity, the reduction of total Kjeldahl and the rate of deposition. The impact on the reduction of COD and electrical conductivity is less pronounced. Operating costs for all experimental conditions were calculated on the basis of data on consumption of electrode mass, voltage and current.
