Abstract:

Persulfate(PS) advanced oxidation process is an effective method to remove pollutants from wastewater. In this process, PS was used as oxidant to oxidize and degrade pollutants after activation. The different activation modes of PS have a synergistic effect on each other, which shows the better pollutant removal effect than simple addition of single activation. The activation methods of PS were reviewed, the activation mechanisms of different types of joint activation including the joint activation between transition metals, joint activation between non-metals and transition metals, and joint activation between non-metals were described. Furthermore, the application status about joint activation of PS in the removal of trace organic pollutants was discussed, and the development prospect of the joint technology to activate PS was prospected.

Key words: persulfate, joint activation, trace organic pollutants, wastewater

摘要:

过硫酸盐(Persulfate,PS)高级氧化工艺是去除污水中污染物的有效方法。该工艺以PS为氧化剂,将其活化后对污染物进行氧化降解。PS的不同活化方式相互联合具有协同作用,表现出超越单一活化简单加和的污染物去除效果。综述了PS的活化方式,阐述了包括过渡金属之间联合活化、非金属与过渡金属联合活化、非金属之间联合活化在内的不同类别联合活化的活化机理,讨论了联合活化PS在去除微量有机污染物中的应用现状,并对联合活化PS技术的发展前景进行展望。
