Název v původním jazyce
Bioleaching of hazardous waste
Popis výsledku v původním jazyce
Landfilling is the least environmentally friendly method of waste disposal because of possible pollution to the environment. The most problematic wastes are dangerous wastes which are often disposed of by combustion. This process reduces their volume but at the same time new types of dangerous waste are formed. The present article focuses on the possibilities of the removal of hazardous properties of waste originating from hazardous waste incinerators (three types of bottom ash and charcoal from flue gas cleaning) by bioleaching. Toxic pollutants originating from waste could be removed by bioleaching with Acidithiobacillus ferrooxidans. The effectiveness of bioleaching was evaluated on the basis of the pollutant content in the aqueous leachates. For the study of relation between the efficiency of bioleaching and the binding of the pollutants in the waste, Tessierʼs sequential extraction was used. The comparison of bioleaching efficiency and the results of sequential extraction show that bioleaching can be used to remove elements which are in exchangeable form or are bound to carbonates, meaning they are bound in bio-available forms. Simultaneously, it was proved that bacterial activity changed the bonds of pollutants in wastes which lead to the increased solubility of pollutant.
