富营养化水体中微囊藻毒素（MCs）去除技术研究进展

当前，随着工业的发展水体富营养化程度日益严重。引起富营养化的主要藻类一蓝藻，能够释放对人体及鱼类具有多器官毒性、遗传性和致癌性的毒素——微囊藻毒素（MCs）。MCs治理技术种类繁多，传统的物理法如：混凝沉淀、膜过滤、活性炭吸附、气浮以及直接过滤只能对简单的处理细胞内的MCs；化学氧化法、光催化氧化法以及高级氧化法虽然能有效处理水体中的MCs．但有成本高、易二次污染和操作复杂等缺点，难以满足日益严格的环保要求；生物酶法除了具有生物降解法所具有的廉价、无二次污染、降解彻底和易操作等特点外，还被刺用来监控水体中MCs，它将成为今后重点研究的技术领域．

Research Progress on Removal of Microcystins(MCs)in Eutrophic Water Body

With the industrial development, the situation of eutrophicated water bodies deteriorated gradually. As the main one of Algae which caused the eutrophication, the Cyanobacteria could released toxins named Microcystins （MCs） which was toxic to human beings, mammals and fishes for its multiple-organ toxicity, Hereditary and carcinogen. However there were a variety of treatment technologies, conventional physical methods such as coagulation Sedimentation, membrane filtration, AC adsorption and flotation only removed MCs inside the Cyanobacteria cells and chemical oxidation, photocatalysis and advanced oxidation processes （AOPs） could decomposed MCs existing in the water which were hard to met the standards of environment because of high cost, secondary pollution and complex operation. Compared with the traditional processes, biodegradation, especially microbial and its enzyme technologies, which had the merits such as low cost, high efficiency, stability and no secondary pollutant, would be the most effective way to degrade MCs completely. Except for the advantages mentioned above, it could be utilized to monitor MCs in the water. So it was regarded as the important field in treatment of MCs in the future.
