浅谈吸附剂在废水处理中的应用

Application of adsorbents in wastewater treatment

在各种废水污染中,工业化废水对水体的污染日趋严重,其不仅对环境造成极大污染,而且也对人类的身体健康构成了巨大威胁。近年来,国内外对吸附剂开展了大量的研究工作,为废水的处理开辟了多条途径。在众多的处理方法中,吸附法因其方便快捷、处理效果好、吸附材料种类多、易获得的特点而被广泛应用。阐述了各类吸附剂的特性及吸附机理及在工业废水中的应用前景,分析和评价了各类吸附剂的特点,并针对目前吸附剂的发展现状,对今后吸附剂的发展趋势进行了展望。

Among all kinds of waste water pollution,the pollution of industrial waste water to the water body is becoming more and more serious,which not only causes great pollution to the environment,but also poses a great threat to people's health.In recent years,a lot of research work on adsorbents has been carried out at home and abroad,which has opened up many ways for wastewater treatment.Among many treatment methods,adsorption method is widely used because of its convenience,quick treatment effect,adsorption material variety,easy to obtain characteristics.In this paper,the applications of activated carbon,fly ash,diatomite and resin in wastewater treatment are reviewed.The characteristics,adsorption mechanism,adsorption mechanism and application prospect of various adsorbents in industrial wastewater were described respectively.The characteristics of various adsorbents were analyzed and evaluated.According to the current development status of adsorbents,the development trend of adsorbents in the future was prospected.
