摘要
磷是水体富营养化的限制性因素,废水除磷是控制水体富营养化的关键,也是回收磷的重要途径之一。本文就含磷废水的处理方法,包括生物法、化学法、吸附法以及结晶法等除磷技术的原理、特点及研究现状进行了详细介绍,综合分析表明,研究价格低廉、选择性好、易再生的水处理方法是今后含磷废水处理领域的主要发展趋势,未来对磷的回收将是水处理过程中的重要环节。
Phosphorus is the restrictive factor of water eutrophication and phosphorus removal is the key point to control this phenomenon, at the same time, it is an important approach to recover phosphorus resource. The treatment methods, principles, characteristics and recent advances are introduced in detail, including biological method, chemical method, adsorptive method, crystallization method and so on. Comprehensive analysis shows that researching wastewater treatment technologies of more economical, efficient and higher selective is the main development trend in phosphorus removal. What＇s more, phosphorus recovery is an important tache in the course ofwastewater treatment in the future.
