| 摘 要： | 综述了各种湿法烟气脱硫技术的原理及特点:石灰-石灰石法、钠碱法在脱硫过程中多以一次利用为主,且易造成二次污染及设备腐蚀;氨法脱硫过程关键在于脱硫液中氨性质的稳定;醇胺法及生物脱硫法多考虑到脱硫液的再生,以减少溶液的损失,保证脱硫液的脱硫性能。指出利用微生物强化可再生溶液脱硫方法作为一种新型的脱硫方式是烟气脱硫值得发展的方向。

| Abstract: | The mechanism and characteristics of various wet flue gas desulfurization (WFGD) technologies were reviewed. Lime/limestone system and sodium alkali may be utilized in single pass desulfurization process, but may cause secondary environmental pollution. For ammonia method, the key factor is the stabilization of the ammonia in the desulfurization solution. Alcohol-amine desulfurization and biodesulfurization methods need the regeneration of the solution in order to decrease losses and keep the performance of the solutions. The regeneration process of the desulfurization solutions containing sulfur compounds assisted by microorganism, as a new method, will represent the trend of development. |
