摘　　要：水体富营养化易引发藻类爆发,破坏水生态健康,威胁用水安全,对水处理设施的运营管理不利。臭氧因具有高效、清洁的特点被广泛应用于除藻,臭氧可灭活并裂解藻类;预臭氧强化混凝可提高混凝除藻的效率;臭氧气浮不投加混凝剂也可高效浮选藻类;在合适的条件下臭氧高级氧化可完全去除藻类,同时可降解大部分有机物。通过对臭氧氧化除藻工艺进行研究,分析和讨论各工艺的性能、机理及影响因素,同时针对除藻工艺的选用与研究提出一些关键问题以作参考。Eutrophication of water bodies can cause algal blooms easily which damages the aquatic health and threatens the safety of water and also be detrimental to the operation and management of drinking water treatment plants.Ozone is widely utilized for algae removal because of ita high efficiency and cleanliness.Ozonation can inactivate and lyse algae.Preozonation can enhance the coagulation process and improve the algae removal.Ozone flotation can harvest microalgae without coagulants.Ozone advanced oxidation can remove algae completely and degrades most of the organic matter under suitable condition.Review in detail the research on algae removal processes based on ozonation.The performance,mechanism and influencing factors of different processes are analyzed and discussed.Some key issues are presented to provide references for the selection and research of algae removal processes.
