PLANT AND METHOD FOR RE-SALINIZATION OF LAKES WITH HEALING WATER

摘要

The invention relates to a plant and a method for re-salinization of lakes with healing water. According to the invention, the plant comprises some basins (1, 2 and 3) arranged in stages and filled with coarse salt (B), connected to a pipe system (4, 5, 6, 7 and 8) and a water pump (9), wherethrough water from a lake (A) is absorbed through a sucker (11) placed at the end of a pipe (8), located above a platform (10), water which is then sent into the first basin (1), located at the highest level, through a pipe (4), the end of which is placed at the bottom of the basin (1), which makes the water level of the said basin (1) rise, washing and gradually dissolving a layer of salt (B), the first salt water formed flowing through an overflow pipe (5) to the bottom of the next basin (2), it gets through the salt layer in the said basin (2), gets out through an overflow pipe (6), which supplies the next basin (3), repeating the previously described cycle, so that, in the end, the salt water with the highest concentration, located in the last basin (3), is discharged, through the overflow pipe (7) thereof, directly into the bottom area of the lake (A), by gravitational flowing. The claimed method consists in filling three basins, arranged in stages, with coarse salt, the first basin being at the highest level, the water from the lake being sucked through a pipe, the admission end of which is above a platform at a depth of 50...60 cm from the surface of the lake, the water being further driven by a pump to get into a pipe, the end of which is placed at the bottom of the first basin, situated at the highest level, the water level in the first basin rises, washing and gradually dissolving the layer of salt, and the first salt water formed flows through an overflow pipe to the bottom of the basin, further the salt water coming from the first basin gets through the layer of salt in the second basin and gets out through an overflow pipe which supplies the third basin, repeating the previously described cycle.
