Abstract
U ovom radu različiti metalni materijali (čelik, aluminijeva legura AA2007 te Zn brodska anoda) ispitani su kao žrtvene anode za obradu procjedne vode komposta. Eksperimenti su provedeni u elektrokemijskom reaktoru šaržnog tipa pod različitim radnim uvjetima planiranim prema Taguchijevom dizajnu L9 ortogonalnog niza. Izvršena je obrada otpadne kompostne vode procesom elektrokoagulacije korištenjem elektroda od različitih materijala pri čemu su se mijenjali brzina vrtnje magnetskog miješala (70, 170 i 270 rpm), početna vrijednost pH otopine (4, 6 i 8) te vrijeme trajanja procesa (10, 20 i 30 minuta). Nakon filtracije tako obrađene vode određene su vrijednosti kemijske potrošnje kisika (KPK) i isparnog ostatka (TS) te analizirana potrošnja i promjene na površini elektroda. Potrošnja elektroda se određivala vaganjem, a promjene površine elektroda su se pratile se mikroskopskom analizom. Na temelju Faradayeva zakona i potrošnje elektroda provedena je analiza operativnih troškova
Abstract (english)
In this paper, various waste materials (steel, aluminium alloy AA207 and Zn ship's anode) are tested as sacrificial anodes for the treatment of compost leachate. The experiments are carried out in a batch-type electrochemical reactor under different operating conditions planned according to Taguchi's L9 orthogonal array design. The effect of different waste metallic material (Fe, Al, Zn), initial pH values (4, 6 and 8), stirring speed (70, 170 and 270 rpm) and contact times (10, 20 and 30 min) on COD and turbidity removals are examined. After filtering the treated water, the values of chemical oxygen consumption (COD) and total solids (TS) were determined, and the consumption and changes on the electrode surface were analyzed. Electrode consumption is measured by weighing, and changes in the electrode surface are monitored by microscopic analysis. On the basis of Faraday's law and consumption of electrodes, an analysis of operational costs was carried out.
