METHOD OF EFFLUENTS AFTERPURIFICATION Russian patent published in 2014 - IPC C02F3/32 

FIELD: process engineering.

SUBSTANCE: invention relates to afterpurification of effluents. Proposed method comprises application of plants great bulrush Scirpus lacustris L., narrow-leaved cat's-tail Typha angustifolia L. and Elodea canadensis Michx planted at the area of prepared terrain. In afterpurification, flow of effluents is forced through at least three structured zones "exposed stretch - reed bed". Central closed zone with space with no plants is formed in every zone of great bulrush of the first row and narrow-leaved cat's-tail of the second row of two-row nonlinear arc convexed along the stream at stretch lower section and combined with Elodea canadensis Michx at stream sides.
