摘要
针对工业废水中去除SO42-的化学沉淀法、物理吸附法、离子交换树脂法、膜分离法和生物法,综述了其研究现状,对各类处理方法的优缺点及应用条件等做了详细阐述,并指出了在去除工业废水中SO42-时,需要结合生产实际灵活联用几种方法,同时生物法和吸附法及其高效吸附材料将是今后的研究重点。
The research status of using chemical sedimentation process, physical adsorption process, ion exchange resin process, membrane separation process and biological process to remove SO4^2- in industrial wastewater was summarized, the advantages, disadvantages and application conditions of different treatment processes were elaborated in detail, it was also indicated that, to remove SO4^2- from industrial wastewater, the mentioned processes should be combined flexibly according to the actual production. Biological process, adsorption process and efficient adsorption materials were pointed out to be the research emphasis in the future.
