Abstract

Povećanje broja stanovnika i rastuća industrijalizacija rezultirali su znatnim količinama otpada i onečišćenja okoliša diljem svijeta. Sa sve većim izazovima u održivom gospodarenju otpadom, problematika otpada postaje sve izraženija. Procjedne vode, koje nastaju kao tekući nusproizvodi prolaskom kroz otpadne materijale, posebno su zabrinjavajuće zbog svoje složenosti i visokog sadržaja organskih tvari. Njihovo ispuštanje u prirodne vodotokove može štetno utjecati na okoliš. Biološka obrada procjednih voda postaje odlučujući čimbenik u njihovom upravljanju, pri čemu se mikroorganizmi koriste za uklanjanje onečišćujućih tvari i poboljšanje kvalitete vode. Među različitim postupcima biološke obrade, bioremedijacija se ističe kao učinkovit pristup zbog svoje održive prakse i ekološke prihvatljivosti. U ovom radu provedena je bioremedijacija procjedne vode iz biootpada u šaržnim i submerznim uvjetima. Fizikalno-kemijskim i mikroskopskim analizama dobiven je uvid u tijek procesa biorazgradnje prisutnih organskih onečišćujućih tvari. Svjetlosnom mikroskopijom dobiven je brzi uvid u promjene sustava tijekom procesa bioremedijacije. Učinkovitost bioremedijacije procjedne vode iz biootpada iznosila je 89 %.

Abstract (english)

Population growth and increasing industrialization have led to considerable amounts of waste and environmental pollution in all regions around the world. With the increasing challenges of sustainable waste management, waste-related problems are becoming more and more apparent. Leachates, the liquid by-products of the passage of waste materials, are particularly problematic due to their complexity and high organic content. Their discharge into natural watercourses can have harmful effects on the environment. Biological treatment of leachates is becoming increasingly important in their management, using microorganisms to remove pollutants and improve water quality. Among the various biological treatment methods, bioremediation stands out as an effective approach due to its sustainable practices and ecological acceptability. In this study, the bioremediation of leachate from biowaste was carried out under batch and submerged conditions. Physico-chemical and microscopic analyzes provided information on the course of the biodegradation process of the organic pollutants present. Light microscopy provided a quick insight into the system changes during the biodegradation process. The efficiency of bioremediation of leachate from biowaste was 89 %.
