Abstract
It has been shown that with air transportation rise it is necessary to increase the efficiency of storm and wastewater purification from the territory of the airports and other air enterprises. It is suggested to use higher aquatic vegetation to protect the environment from airborne pollutants into natural water reservoirs. For further step of final cleanup it is proposed to use aquatic hyacinth – Eichornia. The rationalization for the plant selection is provided, its essential characteristics and the way for extracting pollutants out of the aquatic environment during the metabolism process are described. The technique of experiments on determining the effectiveness of biological wastewater purification within the conditions of the central part of the country is discussed in terms of Moscow region. The measurement results of suspended materials and petrochemicals concentrations in water before and after purification in sediment ponds are presented. The effectiveness of biological purification is shown. The possibility of using water hyacinth for purification of some superficial water reservoirs is also outlined. It is recommended all the year round to use protecting constructions (covers) in open purification plants, then under protected conditions metabolism processes can proceed in the rhizome, stems and foliage of the vegetation even in the autumn-winter period. It is proposed to recycle the used biomass for commercial purposes as a livestock fodder additive under the certain conditions that have been defined. The algorithm of preserving seedlings in the cold season and their subsequent planting in water reservoirs in spring is discussed. It is economically feasible to use biological final purification by aquatic hyacinth but observing the unusual environmental safety measures that have been formulated is required. Practicability of further prospective work on producing specialized ecosystems involving higher aquatic vegetation for nature-like integrated purification of certain types of wastewater was underlined.

Summary
Подчеркнута целесообразность дальнейших перспективных работ по созданию специализированных экосистем с участием высшей водной растительности, для природоподобной комплексной очистки отдельных видов сточных вод. Важнейшей характеристикой эффективности работ [1] по защите водных объектов от антропогенного загрязнения в процессе деятельности аэропортов является величина удельного количества загрязняющих веществ, сбрасываемых в водоемы, отнесенная к числу пассажиров, обслуженных за год. В литературе есть сведения о примерах использования некоторых видов высшей водной растительности [9] для доочистки сточных вод перед сбросом их в водоемы. Проблема повышения эффективности очистки сточных вод аэропортов и им подобных авиапредприятий, а также задача снижения негативного экологического воздействия на водные экосистемы территории места авиационного происшествия являются предметом дальнейшего рассмотрения. Целесообразно оценить перспективность использования высшей водной растительности для защиты среды, окружающей авиапредприятия, от загрязнения
