蓝藻毒素的环境行为及其处理方法研究进展

Advances in research of the environmental behavior of microcystins and their removal technologies

近年来,水体污染、富营养化过程日趋严重.在总结国内外研究的基础上,概述了蓝藻毒素的理化性质、结构及污染现状.简要介绍了蓝藻毒素的环境行为,系统总结了迄今为止各种蓝藻毒素处理方法的进展,并对各种处理方法的优缺点进行了比较.其中光催化、生物法和一些组合工艺如强化混凝气浮都是较理想的去除蓝藻毒素的方法,具有去除率高、投资少以及经济成本较合理的特点.指明了今后蓝藻毒素污染控制和处理的研究方向,为水体中藻毒素的防治提供科学依据.

Water pollution and eutrophication have been more serious recently. Based on the related researches of Chinese and international scientists, this paper reviews the physicochemical properties and structures of microcystins and their current pollution. The environmental behavior of microcystins is concisely discussed as well. Various available microcystin removal technologies are summarized and their advantages and disadvantages are compared. Photocatalytic, biological and some combined techniques such as intensified coagulating floatation are good methods to remove microcystins, which have some advantages such as high removal efficiency and low cost. Future research needs for microcystin pollution control and treatments are identified to provide scientific bases for the prevention of aquatic microcystin pollution.
