The article presents the features of cascade phyto-treatment facilities, bio plateau with an open water mirror. Such structures are similar to natural wetland objects. The plant species on the cascades and their effect in the post-treatment of wastewater are considered. Natural biological treatment of wastewater with algae roots is one of the most effective methods of treatment. This method allows you to clean polluted wastewater without harming the environment. Aquatic plants intensify the purification process, remove biogenic elements, actively using them in their nutrition, remove heavy metals and organic substances from the water and accumulate in the root system, which are difficult to decompose and thus improve the process of self-purification of reservoirs. The article pays great attention to the project «The Resilient Ribbon: A Timeless Legend of Kazan». The essence of the project is the natural self-purification of the city lake Nizhny Kaban in Kazan, where the root system of plants is used to purify water from mixtures, phenols and phosphates, heavy metals and a number of other harmful substances. The results of laboratory studies of water quality after treatment at cascade phyto-treatment facilities are presented.
Key words: Phyto-treatment facilities / bio plateau / higher aquatic vegetation / cascade / plants / Kaban lake
