摘　　要：文章系统综述了碱性矿物水镁石及其煅烧产物在臭氧化净水中的应用及其机理。以活性艳红染料、硝基苯、苯胺、苯酚为例,分别研究了水镁石煅烧前后对不同类型的有机污染物的催化臭氧化降解效果。文章在前文实验的基础上,提出了水镁石煅烧前后的不同催化机理,进一步发展了臭氧化催化理论,为碱性矿物水镁石及其煅烧产物的利用提供了理论上的指导。In the paper, the mechanism and application of alkali mineral brucite and its calcined product in ozonation water treatment were summarized. The azo dye active brilliant red X-3B, nitrobenzene, aniline and phenol were chosen as samples, and the catalysis in presence of brucite and calcined product magnesia were investigated respectively. Based on these experimental results, the different catalysis mechanism of brucite and magnesia were proposed. Then, the ozonation theory was developed further and advice was given to rational application of alkali mineral.
