Study On The Improve And Redesign The Treatment System Of Uranium Mine Wastewater And The Integrated Utilization Of Wastewater

In order to improve and reduce the pollution of uranium mining wastewater to the environment, according the drainage water monitoring data of uranium mine and tailings reservoir waste water treatment station.Combined with the Ionic forms of radionuclides in the waste water、effect factor of ion exchange resin adsorption performance、The leaching process and leaching agent、Classification and process characteristics of ion exchange equipment、pyrolusite. Analyse the treatment effect of the outer wastewater and the changing trend of the treatment facilities.and after full investigation and comprehensive consideration. Combined with the design parameters of current treatment facilities. Study on the problems and reasons in uranium mine wastewater treatment facilities. Put forward the measures and suggestions for the improvement of existing technology. Through the improved process of transformation of the waste reservoir, Flocculation and sedimentation by Barium chloride and magnesium hydroxide to ruduce radium, uranium fluoride, The mother liquor with poly-ferric flocculation, The fluidized bed countercurrent adsorption tower. Improve the waste tailings pH and shorten the replacement cycle of pyrolusite, and so on. Further reduce the concentration of radioactive nuclides in Wastewater, improve the stability of the effluent wastewater. The total alpha radioactivity in wastewater to meet the standard requirements.This paper also proposes to improve the uranium mine economic benefits, reduce environmental pollution, as far as possible to recovery of useful components of wastewater, discusses the recycling, way of various types of waste water make index analysis of comprehensive utilization and economic benefits;...
