摘 要: | 饮用水源藻毒素污染已越来越引起人们的关注。微囊藻毒素(Microcystins,MCYST)是由蓝藻的部分藻属产生的环肽化合物,性质稳定,已被证明具有明显的肝毒性,是肝肿瘤促进剂之一。常规水处理工艺对MCYST的作用效果不理想,多项研究表明臭氧、光化学氧化、氯系氧化物、活性炭以及生物控制等方法能较好地去除毒素。

Study on Microcystins and the Control Methods in Source Water |
| |
Abstract: | Increasing attention has been attached to the pollution of algal toxins in recent years.Microcystins(MCYST),as a major model of the toxins reported,is toxic cylic heptapeptide,which may be produced by some strains of various blue-green algae.MCYST is stable in characters and fairly resistant to degradation.MCYST has been showed to be extremely potent hepa-totoxins and been viewed as a promoter of liver tumor.The general water treatment process cannot remove MCYST efficiently.Some researches show that ozone,chlorine and its oxidants,photochemical oxidization,activated carbon and biological method are effective for removing MCYST. |
