摘要
在简要介绍国内外富营养化现状的基础上,阐述了水域中藻类爆发及伴随藻毒素带来的各种危害;分别对水源水控藻除藻技术(限制营养盐控藻、直接除藻灭藻、生物技术与生态工程)和水厂水中控藻除藻技术(预氧化、混凝沉淀、膜滤、直接过滤、气浮、联合处理工艺)的国内外研究现状和应用动态进行了全面评述;指出了各种工艺技术中存在的问题。为今后实现含藻水的标本兼治及有效控藻除藻提供技术借鉴。
On the basis of brief introduction of domestic and foreign eutrophication status, various hazards caused by algal bloom accompanied with algae toxins are summarized. Research status and application trend of algae control and removal technologies home and abroad for the source water （nutrients limitation, direct removal, biological and ecological engineering） and for the waterworks water （pre-oxidation, coagulation and sedimentation, membrane filtration, direct filtration, air flotation, combined treatment process） are fully reviewed, and problems existing in different technical processes are pointed out, providing technical reference for future development orientation of elimination of the root causes for water pollution by algae bloom and effective algae control and removal.
