饮用水中微囊藻毒素去除技术

微囊藻毒素是从蓝藻中释放出的一种肝毒素，可导致人类、家畜和野生动物的死亡。水中藻毒素的去除有多种方法，但常规水处理工艺对其去除率较低，一般在50％以下，有时甚至出现负去除率。物理法、化学法、光催化氧化法及生物法等对藻毒素的去除效果较好，去除率一般可达90％以上，考虑到处理效果和运行的经济性，以光催化氧化法和生物法较为适宜。

REMOVAL OF MICROCYSTINS FROM PROTABLE WATER

The microcystins is a hepatotoxin released from cyanobacteria and is proved to be responsible for leading to death of person, livestock and wild animal. There are many methods to remove microcystins. But routine water treatment processes have lower removal rate for it, generally being lower than 50%. Physical and chemical methods, photoeatalytic oxidation method and biological method have better removal effect on microcystins; the removal rate generally reached to over 90%.
