摘要
降低废水中磷的浓度是抑制水体富营养化的关键。处理含磷废水的方法有化学沉淀法、吸附法和生物法,本文分别介绍了3种处理方法的原理、特点及技术发展现状。对含磷废水处理技术的发展和废水中磷的回收利用进行了讨论。
Reducing the concentration of phosphorus in wastewater is the key point to curb eutrophication.The methods of removing phosphorus-containing wastewater include chemical precipitation,adsorptive method and biological method.In this paper,the principles,characteristics and technical development status of the three methods have been introduced respectively,and the development of phosphorus-containing wastewater treatment technology and the recycling of phosphorus in the wastewater also discussed.
