摘　　要：文章研究了在臭氧化降解化工有机污染物中具有良好催化性能的水镁石的使用寿命和再生性能。以对苯胺的降解为例,研究结果表明,水镁石具有重复使用六次以及由简单煅烧恢复催化活性的优异再生性能,对化工企业实际废水的催化臭氧化降解也显示了良好的催化性能,研究为廉价水镁石对化工废水处理的实际应用提供了实验基础和科学根据。In this paper,the author studied the life and regeneration performance of the brucite that showed a good catalytic performance in the degradation of chemical organic pollutants.Take aniline for example,the result showed that the brucite has excellent regeneration performance reused six times as well as restore the catalytic activity by a simple calcination.In addition,the catalytic ozonation of chemical factory wastewater over magnesia was also studied.The study found that the catalyst of brucite displayed the excellent catalytic performance not only for the simulate wastewater,but also for the actual chemical factory wastewater.This study provided the experimental basis and scientific basis for the practical application of cheap brucite on the wastewater treatment.
