Abstract

The emission of fluorine-containing waste gas during the production of phosphorus compound fertilizers causes serious environmental pollution, so the development of an efficient resource recovery technology is of great significance. As an efficient and energy-saving separation method, membrane separation technology can effectively remove harmful substances from fluorine-containing waste gas and recover valuable components from it. This paper focuses on the application of membrane separation technology in the resource recovery of fluorine-containing waste gas, and analyzes the influence of factors such as the selection of membrane materials, separation performance, and treatment processes on the recovery efficiency. The experimental results show that membrane separation technology can not only efficiently remove fluorine gas, but also achieve efficient recovery of fluorides in waste gas through appropriate membrane selection and optimization of operating conditions. This technology has strong application prospects and can provide new solutions for environmental protection and resource utilization in the phosphorus compound fertilizer production industry.
