It were used special wooden constructions "kashytsia" and synthetic carrier "Vija" type for the creation of a purifying structure, acting on the principle of "bioreactor". It has been shown that the purifying structure is capable of storing a significant amount of bacteria and invertebrates in their periphery (peryphiton). Study of the dynamics of accumulation of bacteria on the synthetic carrier "Vija", during the summer season, indicates the sigmoid nature of this process. Thus, in the first phase, the process of adsorption of microorganisms on the synthetic carrier proceeds slowly, especially in the protected area of the protected object, where the microbial number is within the limits of 1600 ± 65 colony forming units / ml, which is much lower than the existing sanitary norms. In the future there is a logarithmic dependence and saturation of the absorbing surface by microorganisms. It is shown that regardless of the level of pollution of the aqueous medium, a certain multiplicity of saturation of a synthetic carrier is observed, which is characterized by a accumulation coefficient equal to 14-16 units. In the peryphiton, applied by us fiber carrier "Vija", creates a specific microecosystem, in which the fibrous carrier serves as a kind of model of artificially created nutritional chain. The sanitary-hygienic indicators of surface water served as a criterion for the effectiveness of the treatment structure. After passing through the "bioreactor", contaminated surface water is cleared of organic components, as evidenced by the values of sanitary and hygiene indices (dissolved oxygen, biochemical oxygen consumption, chemical oxygen consumption). Application of purifying structures such as "bioreactor" has led to a significant improvement in water quality, especially in the territories of traditional economic landscapes, as evidenced by a slight excess of the maximum permissible concentration in the main sanitary and hygiene indicators. During the summer season (from June to the beginning of September), maintaining a dynamic balance of the species diversity of the peryphiton "bioreactor" occurs while maintaining a high level of efficiency of the treatment plant.
