Brief content Wastewater treatment plays a key role in sustainable development as a means of ensuring the protection of surface water from pollution. Ozonation is one of the perspective methods of how to remove persistent substances from wastewater and prevent their entrance into the environment. This paper deals with a treatment of an industrial wastewater containing alkylphenols and alkylphenol ethoxylates using ozonation and adsorptive ozonation. Adsorbents used for the adsorptive ozonation included granulated activated carbon (GAC) and zeolites modified with iron oxides and manganese oxides, respectively. From the comparison of alkylphenols concentrations, COD, TOC, ecotoxicity and cytotoxicity of the samples it appears that adsorptive ozonation with GAC and ozonation followed by an adsorption on GAC were the most efficient methods with a great potential for the practical use.
