臭氧催化氧化水中PPCPs的研究进展
Research Progress of Catalytic Ozonation to Remove PPCPs from Solution
【摘要】 由于药物及个人护理品(Pharmaceutical and Personal Care Products, PPCPs)在环境中的持久性或伪持久性特征,会对生物体造成严重危害。然而PPCPs种类复杂,性质各异,常规水处理工艺的去除率不足10%。臭氧氧化能力强,反应速度快、无二次污染,但反应过程中存在臭氧利用率低、反应不彻底等缺点。在臭氧氧化体系中加入催化剂,从而提高了PPCPs的降解效率成为重要的研究方向。根据投加催化剂的存在状态,对臭氧催化氧化进行了总结和展望。
【Abstract】 Pharmaceutical and Personal Care Products(PPCPs) havearoused tremendous attentionin recent years due to theirbioaccumulation andpotential ecological hazards. Itis found thatsome kinds of PPCPs can’t be completely or effectively removed in traditional wastewatertreatment plants. Catalytic ozonation is an effective method to degrade PPCPs. The catalyst can promote the decomposition of ozone and generate active free radicals, enhance the degradation rate and mineralization degree of organic pollutants. According to the existing state of the catalyst, the catalytic oxidation of ozone is summarized and prospected.
