Phenolic compounds in mine effluents impair surface and ground water. Removal of phenolic compounds from mine water is a topical scientific problem and a critical practical task of the environmental security in coal mining. Many flow charts of removal of phenolic compounds from mine water treat effluents with coagulating and flocculating agents. This results in bulk sedimentation, increases salt content, fails to reduce organic pollutants to maximum permissible limit and entails considerable expenses. Aimed to minimize ecological damage by phenolic compounds in mine water, Advanced Oxidation Processes (AOP, Fe3+/H2O2/UV) based on using hydroxyl radicals as oxidizers of organic compounds have been considered. This article gives an illustration of cost calculation in photochemical water treatment by AOP with oxidizers Н2О2, FeCl3 and UV light in terms of water bodies in Vorkuta industrial area (Pechora Coal Basin) polluted with phenols in mine effluents. The damage of water is estimated as 374,714 thousand rubles annually. The current operating cost of treatment of mine waste water with phenolic compounds using a photochemical reactor, considering preset process variables including cost of accumulation of oxidizing agents Н2О2 and FeCl3, and cost of power supply makes 91,673 thousand rubles per year, which is the level of probable averted ecological-and-economic damage caused to the Vorkuta river by phenolic compounds in mine effluents given the introduction of photochemical treatment at the cost of 283,041 thousand rubles annually. The discussed procedure enables estimating the current operating cost of newly designed photochemical reactors for organic matter-bearing waste water purification. The economic appraisal mechanism is applicable to estimating necessary financial means to prevent ecological and economic damage caused to the environment by phenol-containing water discharge from operating mines, and by closure or putting in prolong storage of unprofitable underground and surface mines.
