Research on the Capacitive Deionizing Technology of Pure Water Hydraulic Transmission in Coal Mine

Abstract

In order to reduce the mine drainage and improper treatment caused by a large amount of water resources waste and environmental pollution. In this paper, the capacitive deionizing technology is applied to the stage of mine water treatment, and the constant voltage desalting mode is used to test and analyze, and the method is compared with that of reverse osmosis water treatment. The results show that the capacitance to ion technology power consumption depends largely on the salt ion concentration, if the water salinity is less than 1g/L, capacitance to ion method than general energy consumption is lower than 0.5kWh/m³, and reverse osmosis technology in 1m³ per purified brine process need to consume more than 2kWh of energy, and energy consumption with the salt ion concentration has no relevance. It can be seen that the capacitive deionizing technology has the advantages of low cost and low energy consumption, and can be applied in the stage of mine water post-treatment.
