废物衍生吸附剂的制备、应用和再生

Preparation,Application and Regeneration of Waste-derived Adsorbents

许多研究表明:吸附是一种去除有机污染物有效且经济可行的方法。生物炭作为一种废物衍生的绿色吸附剂,具有许多优势,例如成本低廉、可回收再利用且能够实现废弃物的资源化。本文总结了生物炭的来源、生产条件以及在有机污染物去除方面的研究现状;阐述了生物炭对有机污染物的吸附机理并总结了其再生方法;研究和分析了其工程应用、经济效益和环境效益;预测了生物炭吸附技术的发展前景。

More and more attention has been paid to environmental problems because of the increasing pollution.Many studies have shown that adsorption is an effective and economical way to remove organic pollutants.Biochar,as a green adsorbent derived from waste,has many advantages,such as low cost,recyclable and can realize the recycling of waste.This paper summarizes the source,production conditions and research status of biochar in the removal of organic pollutants;Describes the adsorption mechanism of biochar to organic pollutants and summarizes its regeneration methods;Researched and analyzed its engineering application,economic and environmental benefits;and forecasts the development prospect of biochar adsorption technology.
