Abstract
Korištenjem vode nastaju otpadne vode koje je potrebno na određeni način zbrinuti ili podvrgnuti različitim postupcima pročišćavanja prije ispusta u vodna tijela. U procesu kompostiranja nastaju procjedne vode koje su onečišćene organskim i anorganskim štetnim tvarima i kao takve zahtijevaju obradu/tretman prije njihovog ispuštanja. Uslijed industrijalizacije i porasta standarada, nastaju sve veće količine otpadnih voda složenog sastava, za koje treba primijeniti i složenije postupke obrade. Danas je naglasak na razvoju hibridnih procesa koji kombiniraju ili integriraju dva ili više različitih fizikalnih, kemijskih i bioloških postupaka. U ovom radu analizirat će se hibridni proces elektrokoagulacije i sintetskog zeolita različite veličine čestica. Tijekom procesa određeni su sljedeći pokazatelji: pH vrijednost, električna vodljivost, kemijska potrošnja kisika (KPK), mutnoća, ukupni isparni ostatak. Također je provedena i analiza operativnih troškova korištenjem Faradayeva zakona i podataka o utrošku masa elektroda. Rezultati pokazuju da odabir materijala elektrode, veličina čestica korištenog zeolita i gustoće struje utječu na efikasnost uklanjanja KPK i mutnoće, brzinu taloženja te potrošnju elektroda. Polazna otopina je jako složenog sastava, opterećena s velikom količinom teško razgradljive organske tvari koja se nije značajno razgradila u jednostupanjskom postupku hibridnog ECZ. Rješenja su u dvostupanjskim ili višestupanjskim procesima.
Abstract (english)
The use of water creates wastewater that needs to be disposed of in a certain way or exposed to various purification procedures before being discharged into water bodies. In the process of composting, leachate is produced that is contaminated with organic and inorganic harmful substances and as such requires treatment before its discharge. As a result of industrialization, increasing amounts of wastewater with a complex composition are produced, for which should be applied more complex treatment procedures. Today, the emphasis is on the development of hybrid processes that combine or integrate two or more different physical, chemical and biological processes. This paper will analyze the hybrid process of electrocoagulation and synthetic zeolite with different particle size. During the process, the following indicators were determined: pH value, electrical conductivity, chemical oxygen consumption (COD), turbidity, total solids. The results show that the selection of the electrode material, the particle size of the used zeolite and the current density affect the COD and turbidity removal efficiency, the deposition rate and the electrode consumption. The starting solution has a very complex composition, contains a large amount of hard to degrade organic substances that were not significantly degraded in the one step process of the hybrid ECZ. The solutions are in two-stage or multi-stage processes.
