MECHANISMS OF INTRODUCTION OF THE TECHNOLOGY OF THE CLOSED CYCLE OF USE OF WATER IN THE CONDITIONS OF OPERATION OF AN ICE RINK

Abstract

The article reveals the mechanisms of introduction of closed cycle water use technology in the conditions of ice rink operation. The economic component in terms of resource conservation, the use of closed cycle technology of water use is substantiated. It is emphasized that the closed cycle of water use in the conditions of ice rink operation is a system of industrial water supply and drainage, in which repeated use of water during the formation and maintenance of ice is carried out without discharging wastewater and other water into natural reservoirs / sewers, etc. It is noted that the formation of ice cover is carried out by pouring water that has undergone multi-level purification of impurities and dissolved gases during the main stages of purification: pre-purification of water - to remove coarse impurities and chlorine, dissolved iron and organic compounds; obtaining purified water - there is almost complete purification of water from all salts and other compounds and its softening; deep water purification - allows you to remove dissolved gases and impurities. The scheme of water reuse in the production of ice for the ice sports ground is given, the technological process has the following main stages: water from the central water supply enters the installation of purification and softening; through the cartridge filter, passing through the heat exchanger water moves to the hot water tank; using a pump, water is fed to the arena to fill the ice cover; melt water obtained from ice chips enters the mixing tank from where the pump is pumped to the beginning of the water treatment cycle. It is emphasized that the implementation of this technology will increase production efficiency and reduce the economic burden. The scheme of the reusable water treatment plant has been developed. It is emphasized that melt water obtained from ice chips has a low concentration of impurities, so it can be reused as needed. It is accepted that the mixing tank at the beginning of use contains tap water, which is saturated with various components. Since the concentration of components is constantly changing (depending on the degree of water purification, season, local water supply, etc.), to determine the maximum concentration of impurities in the work proposed a mathematical component that will calculate the required degree of recycling for better quality end product.
