METHOD OF RESERVOIR WATER AREA LOCALIZATION OF POLLUTANTS ENTERING RESERVOIR FROM TRIBUTARIES AND DRAINS Russian patent published in 2018 - IPC E02B3/02 

FIELD: environmental protection.

SUBSTANCE: invention relates to the field of environmental protection and is intended for the restoration of ponds, lakes and reservoirs, as well as reducing the level of pollution and siltation of their main volume by depositing and localizing pollutants (suspended particles, anthropogenic debris, plant debris) in a limited area of the reservoir, falling into the reservoir from tributaries and with sewage from sewage and storm collectors, including permanent and emergency discharges of contaminants. Invention can also be used to stop the degradation of the basin, if this reservoir has lost the ability to support the self-cleaning process. Way of localization in the water area of the reservoir of pollutants entering the reservoir from tributaries and drains includes the erection of water-blocking water flow of hydraulic structures with a regulated culvert regime. Disinfecting hydraulic engineering structures are carried out in the form of a bulk dam closed on the shore of the reservoir, placing it in the water area of the reservoir opposite the mouth of the tributary or drain, covering the whole width of the estuary. Inside the fenced enclosing dam the parts of the reservoir deepen the bottom, extracting, at least, base sediments and transporting them to the shore of the reservoir. In the enclosing dam and / or the fenced part of the reservoir, drainage hydraulic structures are built.

EFFECT: technical result of the proposed method is expressed in a significant decrease in the intake of suspended particles, pollutants, anthropogenic debris and plant residues in the main water area of the reservoir and their localization in confined fenced areas of ponds (ponds, lakes and reservoirs), that makes it possible to reduce the material and energy costs of cleaning water from pollution, and also significantly improve the ecological and sanitary condition of the reservoir and reduce the rate of its degradation, and in some cases restore its ability to self-purification, especially for overgrown and overgrown lakes.
