摘　　要： 微污染水源水中藻类大量繁殖问题日益突出,许多水厂面临着高藻期水处理困难。二氧化氯作为环境友好型消毒剂,用于饮用水净化预氧化除藻,是一种具有应用前景的技术。该文综述了目前国内外二氧化氯预氧化除藻和藻毒素的效果、副产物的产生和除藻机理等各个方面的研究成果和进展,并对使副产物不超标的二氧化氯的投加量进行了讨论,对二氧化氯预氧化除藻技术在未来的发展进行了展望,提出了现场制取二氧化氯的生产成本是二氧化氯预氧化除藻技术应用尚需进一步探讨的问题。 The phenomenon of algal bloom in the micro-polluted source water has become increasingly prominent, many waterworks are facing difficulties in water treatment during the high algae period. Chlorine dioxide, which is an environmentally friendly disinfec- tant, use in pre-oxidation removal of algae in drinking water purification, which is a promising technology in applications.The current main achievements and progresses were reviewed from these aspects： the effects of pre-oxidation removal of algae and algal toxins by chlorine dioxide, the by-products production and the mechanism of algae removal,and the chlorine dioxide dosage of its by-products in limited values were discussed . The development of algae pre-oxidation removal by chlorine dioxide in the future was anticipated, but the production cost of preparation on-site ought to be further studied in the applications of the technology of algae pre-oxidation removal by chlorine dioxide in future.
