Irapetian T. The closed cycle of water supply of plants of chemical treatment of water of the enterprises of heat-and-power engineering

The technology of treatment of waste water from natrium-cation exchanger unloading (regeneration) is offered which consists in the specified waste water treatment by soda-lime method with the subsequent return on regeneration. It allows to create a closed circulating cycle of rinsing water of natrium-cation exchangers. In addition the quantity of regeneration waste water is considerably reduced and the economy of the table salt is achieved. The advanced design of an open hydrocyclone for joint waste water treatment from loosening of natrium-cation exchangers media and rinsing of waters of mechanical filters is offered. The hydromechanical parameters of the suspended substances contained in a mix of the speci-fied waste waters are determined. The mathematical model for definition of sizes of a gradient of speed of water flow and hydraulic fineness of floccula formed at waste water treatment are offered. Water and salt (material) balances of the existing and recommended water supply and sewerage systemsof plants of chemical treatment of water at TPS and HPP are estimated.
