亚硫酸钙湿式氧化技术的研究进展

A Review of Wet Oxidation Technology of Calcium Sulfite

本文论述了应用湿式石灰石-石膏法脱硫工艺对解决我国火电厂二氧化硫污染问题的重要意义,进一步指出处理好该工艺产生的废渣———亚硫酸钙浆料是一个亟待解决的问题。为此本文就反应机理、温度、pH值、催化剂、氧浓度和反应阶段等分项,具体讨论了国内外目前对亚硫酸钙湿式氧化机理研究的进展,并对我国这方面研究的继续开展提出了一些建议。

The importance of the application of limestone-gypsum wet flue gas desulfurization process to the problem of SO2 produced by power plants of our country is discussed in this paper ,it is pointed out by the author that the waste (calcium sulfite slurry) from this process is in urgent need of being disposed . The research progress of wet oxidation mechanism of calcium sulfite of foreign counties is introduced in different aspects,such as reaction mechanism, temperature, pH, catalyst, concentration of oxygen and stages of the reaction. Several opinions of the development of wet oxidation technology of calcium sulfite of our country is presented by the author finally.
