【 摘 要 】

The article deals with the problem of the shortage of fresh water and the desalination of sea water as one of the promising options for its solution. For the Crimean region the issue of desalination is the most urgent, taking into account its geographical peculiarities. The chemical composition and thermophysical properties of the Black Sea waters are presented. The technological scheme of the station for the preparation of drinking water from the waters of the Black Sea by the method of distillation desalination is presented and considered in detail. To ensure the manufacturability water must comply with the following requirements: the boundaries of the zones of the sanitary protection of water intake should be at least 200 m in all directions of the waters; water intake facilities should be equipped with a mesh filter to capture floating algae, water intake should include water treatment with biocidal agents (chlorine, copper sulphate etc.) with a view to their destruction and subsequent deposition, introduction of water in the chalk priming (with the value of the fraction 10-40 MK) at the rate of 8-15 kg/m3 apresentamos water, polyphosphates up to 10 g/m3 of sulfuric acid 150 g/m3, organic antiscales "Belgard EV" or PAF-13A - 10 g/m3; water should be subjected to deaeration. A water clarification station is necessary, as the evaporation plant should be feeding clarified water, containing dissolved oxygen and carbon dioxide, and not prone to scaling. Under the clarification of water, in the general sense, is understood the removal from it of suspended particles of organic and inorganic origin. The need for biocidal and antiscaling treatment is determined by experimental testing, but a good installation of clarification of sea water significantly reduces the need for this step.
