- 摘要:
- 臭氧-生物活性炭（O3-BAC）工艺在我国水厂应用范围较广，部分水厂已进入活性炭更换或再生阶段，大量废弃活性炭的合理处置成为研究热点。对失效活性炭进行再生，可以有效恢复吸附性能、实现循环利用，具有显著的社会经济效益。总结了自来水厂失效生物活性炭（BAC）再生技术的研究及应用现状，包括再生周期、再生方法和再生应用成果。在此基础上，结合目前“碳达峰”的大背景，从经济性、环保性、针对性等角度探讨了现有活性炭再生工艺存在的问题，并对后续发展方向进行了展望。
- Abstract:
- Ozone-biological activated carbon (O3-BAC) process has been widely used in China. At this stage, the reasonable disposal of waste activated carbon has been focused on by the water treatment industry when facing a large amount of activated carbon replacement or regeneration. The regeneration of ineffective activated carbon can effectively recover the adsorption performance of BAC and realize recycling, which has significant social and economic benefits. The research and application status of the ineffective biological activated carbon (BAC) regeneration technology were summarized, including the regeneration cycle, regeneration methods and application results of BAC. In addition, the existing problems of the current regeneration process were discussed for the loss of economy, environmental protection and pertinence. The future direction was also be prospected combined with the current background of “carbon emission peak”.
