Abstract

Abstract

Given the problems of acid fluorine-containing wastewater from large abandoned graphite mines left over from history, such as large volume, difficult dosing of deep water, low reaction efficiency, serious pollution and less treatment experience, we explored its controlling mode, taking Yueshi Mine wastewater in Nanshu Town, Laixi in Shandong Province as the research object. Based on the laboratory wastewater treatment test, the remediation agent was optimized. Based on the field investigation, through the construction of a three-dimensional mine model and hydrodynamic model calculation, the effect of water displacement under different operating conditions was simulated, and the optimal technological scheme was determined. Finally, the scheme of compound remediation agent with in-situ water exchange was put forward. After treatment, the pH value of mine wastewater reached about 7, and the fluoride concentration dropped below 30 mg/L, reaching the wastewater treatment goal. The water pollution remediation technology system established in the treatment process provide a reference for large-scale acid fluoride wastewater treatment in other areas.
