Zusammenfassung: | FIELD: agricultural and a hydrotechnical construction and the sewage and waste water draining. ^ SUBSTANCE: the invention is pertaining to the field of the agricultural and hydrotechnical construction and the sewage and waste waters draining. The technical result of the invention is creation of the reliable in operation and efficient screens, the increase of the filtration surface and the specific volume of the filtered waters, the high quality of purification of the natural waters, the waste waters, the discharge waters and the manifold-drainage waters. The labyrinth screen contains the channel, the settling tank, the rubbish-trapping lattice, the filtering components made in the form of the separate screens-cartridges filled by the filtering materials. The filtering components are mounted at the bottom of the settling tank and inserted to meet the edges of the maximum levels of the water in several mazes facing alternately to the direction of the water streams with their inlets-outputs and dead ends. The open ratio of the screens-cartridges from the first up to the last maze decreases. ^ EFFECT: the invention ensures creation of the reliable in operation and efficient screens, the increase of their filtration surface and the specific volume of the filtered waters, the high quality of purification of the natural waters, the waste waters, the discharge waters and the manifold-drainage waters. ^ 2 cl, 3 dwg, 1 ex |
