摘　　要：TiO_(2)光催化技术能有效降解蓝藻毒素、异嗅物质等蓝藻代谢物,提升饮用水水质。实际水源中蓝藻代谢物种类复杂,而现有研究主要集中在TiO_(2)光催化技术对微囊藻毒素的处理上,对于其他常见蓝藻代谢物的处理效果缺乏系统的对比分析。因此,基于常见蓝藻毒素与异嗅物质的毒性和特点,分析了不同TiO_(2)光催化技术对水中蓝藻毒素、异嗅物质以及藻细胞-藻毒素复合污染物的降解效果,并探讨了TiO_(2)光催化除藻技术在水厂应用的可行性。Cyanobacterial metabolites such as cyanobacterial toxins and odoriferous substances can be effectively degraded by TiO_(2) photocatalytic technology to improve drinking water quality.The types of cyanobacterial metabolites in the actual water source are complex.Existing research mainly focuses on the treatment of microcystin by TiO_(2) photocatalysis,and the treatment effect of other common cyanobacterial metabolites is lacking systematic analysis.Therefore,based on the characteristics of common cyanotoxins and odors,the degradation effects of different TiO_(2) photocatalysis on cyanotoxins,odors and algal cell-toxin complex pollutants in water are analyzed.The feasibility of TiO_(2) photocatalysis on algal treatment in WTPs is also discussed.
