Abstract

U ovom radu analizirane su fizikalno-kemijske, mikrobiološke i ekotoksikološke karakteristike dobivenih uzoraka nakon elektrokemijskog procesa(elektrokoagulacije) pročišćavanja. Pročišćavane su zauljene otpadne vode mineralnog podrijetla koje se dobivaju postupkom pročišćavanja dimnih plinova iz procesa uplinjavanja mulja s uređaja za pročišćavanje otpadnih voda. Ispitivane fizikalno-kemijske karakteristike su pH vrijednost, količina otopljenog kisika i električna vodljivost uzoraka na pripadnim elektrodama te analiza ukupne količine ugljika. Mikrobiološka karakterizacija se radila na hranjivom i malt agaru, a ekotoksikološka karakterizacija na morskim bakterijama Vibrio fischeri. Rezultati navedenog istraživanja ukazuju jeli potrebno dodatno pročistiti otpadnu vodu nakon pročišćavanja elektrokemijskim procesom elektrokoagulacije s obzirom na granične vrijednosti prema Pravilniku o graničnim vrijednostima emisija otpadnih voda.

Abstract (english)

In this work, the physico-chemical, microbiological and ecotoxicological characteristics of the samples obtained after the electrochemical process (electrocoagulation) of purification were analyzed. Oily wastewater of mineral origin, which is obtained by the process of purifying flue gases from the process of gasification of sludge from wastewater treatment plants, was purified. The tested physical and chemical characteristics are the pH-value, the amount of dissolved oxygen and the electrical conductivity of the samples on the corresponding electrodes, as well as the analysis of the total amount of carbon. Microbiological characterization was performed on nutrient and malt agar, and ecotoxicological characterization on bacteria Vibrio fischeri. The results of the mentioned research indicate whether it is necessary to additionally purify the waste water after purification by the electrochemical process of electrocoagulation. That is, whether the results of the determined characteristics were obtained in the limit values according to the Rulebook on the limit values of waste water emissions.
