摘要:

吸附由于其高效、低成本、易操作等特点,是目前国内外应用最广泛、最有效的废水处理方法之一。废水成分复杂,尤其是存在的背景离子会通过改变吸附剂和吸附质的相互作用影响有机物的吸附效果,造成主要吸附机制难以确认、吸附条件难以优化等问题。因此,研究离子强度对废水中有机物吸附性能的影响是提高吸附处理废水效果的重要途径。本文以吸附剂种类进行分类,阐述了在最常见氯化钠盐存在条件下钠离子和氯离子对于各类吸附剂吸附分离废水中有机物的影响,总结了各个研究者对此所做的研究,并以此展望了在离子存在条件下吸附剂在废水处理中的应用发展,指出开发新型、高效、经济、绿色、环保的吸附剂必将成为未来的发展趋势。

Abstract:

Adsorption is one of the most widely and effective wastewater treatment methods at home and abroad due to its high efficiency, low cost and easy operation. However, the composition of wastewater is complex and the existing background ions will affect the adsorption effect of organic compounds by changing the interaction between adsorbents and adsorbents, causing the problems such as difficult to confirm the main adsorption mechanism and optimize the adsorption conditions. Therefore, it is a significant way to study the effect of ionic strength on the adsorption performance of industrial wastewater. The paper classified the types of adsorbents and expounded the effects of sodium ion and chloride ion on adsorption of organic matter in wastewater under the most common conditions of sodium chloride. Meanwhile, the adsorption mechanism under ion presence condition was preliminarily explained via summarizing the research done by various researchers, and the application and development of adsorbent in wastewater treatment under the ion presence condition were prospected. The development of new, high-efficiency, economical, green and environmentally friendly adsorbents would definitely become the trend of future development.

Key words: ionic strength, adsorbent, water treatment, organic pollutants
