MINE WATER TREATMENT BY ELECTRICAL DISCHARGE TO REDUCE SALINITY



In preparation, development and production mining, one of the pollutants to the environment is contaminated water. Conventional contamination of water flows to ground surface is mineralization and solid suspension. Mineralization is usually connected with salts of different metals, organic and inorganic, alkali and acid compounds. Suspended solids are removed from water by precipitation, or filtration through soil and embankments. Purification of dissolved compounds is carried out by chemical agents or by physical treatment using, inter alia, the known methods of thermal action, electrolysis and discharge. This article gives a review of water treatment by discharge as these methods exhibit the highest efficiency of water purification at low energy consumption with the current wastewater technologies. The results of destruction of inorganic impurities in water by electric discharge are reported. The effect of water treatment by electrical discharge aimed to remove ions of heavy metals is described. The principles of creation of streamer discharges in centimeter intervals above water surface under the atmospheric pressure are presented. It is shown that the integrated treatment by electrical discharge, physicochemical factors and varied streamer discharge frequency radiation results in destruction of organic and inorganic impurities in water. The application of the methods based on electrical discharge is a promising line of development in the technology of wastewater treatment and neutralization. Energy of electrical discharge changes chemical characteristics of water under treatment, influences content of ions and structure of dissolved organic substances in water and affects vital capacity of microorganisms without addition of chemical agents.
