Popis:	Many studies have investigated the effectiveness of a variety of technologies for treatment of industrial wastewaters with increased concentration of dangerous organic matter. Nowadays, there are many ways to solve these kind of problems: biological and enzymatic processes, membrane and electromembrane technology, oxidation and advanced oxidation processes (AOP), evaporation and many others. All of the methods have their advantages, but also economical and technical limits of their usability. In our case, we dealt with a problem of landfill leachate treatment. We used reverse osmosis, ozonation and Fenton’s reaction in various combinations to reduce the organic matter content in the wastewater from the landfill. The AOP processes we used did not achieve complete destruction of the organic compounds, but only degraded to simpler organic compounds. The best result was achieved by combination of ozonation and reverse osmosis.
