FIELD: construction. ^ SUBSTANCE: water self-treatment system comprises an overflow chute, walls and inclined filtering nets of which form a connection that is wedge-like in its cross section, and its top is at the level of grooves between approaching waves. The system comprises one or several structurally finished modules consisting of joined sections. Each section comprises an overflow chute of cross section with rectangular shape with hollow tight float compartments arranged along the lower part of its side walls and having triangular cross section. On the shelves inclined downwards and arranged along the tops of tight float compartments facing outside the tops, there are longitudinal edges of flexible overflow mats floating on water and directed inside the overflow chute, which also interact with the inner surface of inclined filtering nets. Cross edges of overflow mats are laid into shelves of end walls of the overflow chute that are bent inside and are pressed with transverse framing planks of the inclined filtering nets. Along the perforated bottom of the chute there is a tightly laid porous filtering material with low hydraulic resistance. Along the side walls above the tight floating compartments there are through windows arranged. On top the overflow chute is covered with detachable meshed trays to collect dirt captured by the inclined filtering nets. ^ EFFECT: invention makes it possible to provide water treatment in natural and artificial water reservoirs of different purpose. ^ 2 dwg |
