摘　　要：介绍含磷化氢废气的排放标准,简述含磷化氢废气处理及综合利用技术,并分析其优缺点。提供了一种焚烧炉+一级水洗+二级化学洗涤处理磷化氢废气流程,介绍主要设备及其规格型号,以及工程设计特点。该方法磷化氢去除效率99.998%,磷化氢排放质量浓度0.15 mg/m^(3),排放速率0.975 g/h,低于DB 31/933—2015中排放限值。The emission standards for phosphine containing waste gas is introduced, the treatment and comprehensive utilization technologies for phosphine containing waste gas are briefly described, and their advantages and disadvantages are analyzed. A process for treating phosphine containing waste gas using an incinerator, primary water washing, and secondary chemical washing is provided. The main equipment,specifications, and engineering design features are introduced. The removal efficiency of phosphine using this method is 99.998%. The emission concentration of phosphine is 0.15 mg/m^(3), and the emission rate is 0.975 g/h,which is lower than the emission limit in DB 31/933—2015.
