摘要
探讨了饮用水处理的各工艺过程对藻毒素的去除作用,并根据前期已进行的实验对各工艺的优化组合进行了讨论,认为以气浮代替沉淀,并附之以粉末活性炭吸附预处理可有效地去除藻毒素;对没有条件改造沉淀池的水厂可暂时采用预氯化和粉末活性炭吸附组合的工艺也可达到较好的效果;对生物预处理工艺进行适当的强化,可达到对有机物、藻类、藻毒素等物质的有效去除。
Effectiveness of common water treatment processes in removing algal toxins was reviewed. Air floatation employed in conjunction with powdered activated carbon pretreatment is viewed as the most attractive process for removing the toxins from the raw water. The combined process of pre-chlorination and PAC treatment is also effective. Proper enhancement to many existing biological pre-treatment systems may accomplish the objectives of removing some target organic pollutants, algae and algal toxins.
