吸附除磷剂的研究进展

Research Progress in Phosphorus-removal Absorbents

磷元素是导致水体富营养化等现象的关键因素之一,对我们的用水安全已造成了巨大影响,因此磷的去除是亟需解决的重要环保问题。吸附法作为重要的除磷技术之一,具有处理能力强、材料来源广泛、运行成本低等优点,已在众多实际工程中得到应用。本文结合近年来污水吸附除磷领域的最新动态,根据吸附剂的来源和组成的综合考虑,分类介绍了天然无机基、可再生资源基、废弃物基、碳基、合成无机基和其它新型除磷剂的研究现状,展望了吸附除磷剂的未来研究方向。

Phosphorus element as one of the key factors in water-body eutrophication,has had a great impact on our water safety.Therefore,phosphorus removal has become an important environmental problem urgently to solve.Adsorptionmethod is a very important de-phosphate technology and has many advantages,such as strong absorbing capacity,abundant material,low cost and so on.This method has also been widely used in many practical wastewater treatments.In this paper,combined with the latest development in the field of wastewater adsorption and phosphorus removal in recent years,according to the comprehensive consideration of the source and composition of adsorbents,the research status of natural inorganic based,renewable resource based,waste based,carbon based,synthetic inorganic base and other new phosphorus removal agents are introduced,and the future research direction of adsorption phosphorus removal agent is prospected.
