MODULE OF A PHYTOSYSTEM FOR BIOLOGICAL PURIFICATION OF INDUSTRIAL WASTE WATER FROM MINERAL CONTAMINANTS Russian patent published in 2022 - IPC C02F3/32 

FIELD: treatment of water.

SUBSTANCE: invention relates to the field of environmental protection, including that in the Arctic conditions, in particular, to the technology for phyto-purification of natural and anthropogenic water bodies or quarry waste water in settling ponds from mineral contaminants. The claimed module of a phytosystem, like known modules, comprises a frame with a biological load, and differs from known modules in that the frame 1 consists of, interconnected, a rigid base 3 made of a material with positive buoyancy, a mesh cage part 4 and an anchor 5, the biological load 2, consisting of live perennial native aquatic plants, is located freely in the cage part 4 of the frame 1. The base 3 of the frame 1 may constitute a rectangle assembled from plastic pipes with bends, the cage part 4 may be made conical of a plastic mesh and attached with plastic ties or a nylon cord to the base 3 and the anchor 5, wherein one or multiple interconnected synthetic bags with stones weighing 10 to 15 kg can be used as said anchor. Floating hook-moss (Warnstorfia fluitans), lesser bladderwort (Utricularia minor L.), intermediate bladderwort (Utricularia intermedia), common bladderwort (Utricularia vulgaris), alternate (Myriophyllum alterniflorum), spiked (Myriophyllum spicatum), whorled (Myriophyllum verticillatum) can be used as live perennial native aquatic plants.

EFFECT: increase in the efficiency of biological purification of industrial waste water from mineral contaminants, reduction in the duration of formation of phytocenoses, reduction of the negative environmental impact.
