The article obtains a broad literature review on issue of drinking and industrial waste waters treatment. Substances that strongly impact on the hormonal system of living organisms (Endocrine Disrupting Compounds or EDC-type substances) are mostly in a focus. Composition/structure of the most typical substances, affecting hormonal balance of man and their classification are given. The paths of getting the indicated matters into environment are described. The short analysis of difficulties of analytical determination of EDC-substances are given. The basic methods of this kind pollutants removing from different types of water are critically considered: coagulation, adsorption on activated carbon, oxidization, biological and membrane methods, ozone and chlorine. The article contains 25 references.

Keywords: substances, hormonal system, living organisms, composition and classification, sewages, treatment, coagulation, adsorption, activated carbon, destruction, ozone, chlorine, biological treatment, membrane methods.

The review of data of the literature concerning the combined application of chlorine with ultraviolet irradiation (UVI) or ozone is presented. The analysis has shown, that efficiency of such combination in essential degree depends on a number of conditions which can be divided on two groups: the first – an optimality combination of certain doses for UVI and chlorine; the second – difference of influence of рН and temperatures for ozone and chlorine on efficiency of their combination with UVI.

Key words: water, purification, disinfection, chlorine, UVI, ozone, combination.
