The modern state of the most water bodies and coastal zones does not comply with the maximum permissible standards. Water pollution indicates the need for water treatment systems. For this goal, the proposed were used of biological engineering structures with higher aquatic vegetation– bioplato (floating plant islands). The cleaning process occurs due to the natural ability of a number of living organisms and plants to absorb, decompose and recycle pollutants. In the course of the experiment, a set of successively placed containers of wastewater containing certain concentrations of heavy metals and petroleum products was assembled. The imitation biosystem of the plant– microorganisms was represented by rhizomatous plants of the Iridaceae and Typhaceae family, represented Tipha Gracilis and Iris Pseudacorus L and anaerobic microorganisms. A comparative analysis was made of data from the control group of plants and the working group. Also, data on the dynamics of cleaning bioplato on individual components and its combined action with the use of prolonged-action biologics and chelate complexes depending on the temperature profile, various regimes circulation of water flows and aeration. The magnitude of bio – and phytomass needed for wastewater treatment has been revealed. The result was investigated the effects of various agents stimulating the extraction (accumulation) of plant contamination at various concentrations of heavy metals and petroleum products. As a result, working approaches were obtained for the creation of highly efficient mobile combined floating bioplats adapted for temperate climate zone. A method of “building up” the root system was also proposed, which yields significant results from an active bacterial film necessary for cleaning wastewater. Creation of the process of degradation in the autumn-winter period through the use of strains of ana erobic microorganisms in the aggregate action with prolonged-action biologics.
