生物质废弃物柚子皮作为潜在吸附剂用于废水处理

Biomass Waste Pomelo Peel as a Potential Adsorbent for Wastewater Treatment

生物质废弃物柚子皮作为一种潜在、有效的低成本吸附剂,被研究用于废水处理。首先,介绍了柚子皮的物理化学性质,分析了其天然具备优异吸附性能的原因;然后,重点介绍了柚子皮对含重金属废水、放射性废水、印染废水、有机废水、医药废水、含氟废水、含油污水等各类废水的处理现状,探讨了对柚子皮吸附剂再生利用的可行性。结果表明,柚子皮具有良好的可重复利用性和较高的稳定性,有潜力成为一种技术可行、以废治废、环境友好型的吸附材料。

A research has been carried out on the wastewater treatment by pomelo peel,a biomass waste,as a potential and effective low-cost adsorbent.Firstly,an introduction has been made to the physicochemical properties of pomelo peel,followed by an analysis of the reasons for its excellent adsorption properties.Then,a brief introduction has been made to the treatment performance of pomelo peel on wastewater containing heavy metals,radioactive wastewater,printing and dyeing wastewater,organic wastewater,pharmaceutical wastewater,fluorine wastewater,oily wastewater and other wastewater,with a tentative inquiry made into the feasibility of regeneration and utilization of pomelo peel as an adsorbent.The results show that pomelo peel is characterized with a good reusability and high stability,with a potential to provide a feasible,waste-to-waste,environmentally friendly method for wastewater treatment.
