摘要
微污染饮用水源水中的藻类对供水水质和饮用水安全影响较大。大量存在的藻细胞,不仅会产生异味,还会向水体中释放藻毒素,采用常规水处理工艺除藻效能较差。重点介绍了臭氧预氧化、臭氧强化混凝以及臭氧-粉末活性炭联用工艺对微囊藻毒素的去除工艺,这种臭氧及其联用工艺对保证饮用水水质的安全性具有重要意义。
Algae in micro-polluted drinking water have great influence on drinking water quality and drinking water safety. Massive algal cells, not only odor, but also release of algal toxins in water. It is poor algae removal efficiency by conventional water treatment process. This article focuses on removal of microcystis toxin by ozone oxidation, ozone-enhanced coagulation and ozone-powdered activated carbon combined process. It is important to ensure the safety of drinking-water quality.
