摘要
给水厂污泥对多种水体污染物有良好稳定的吸附性能,在水体净化方面具有很大潜力。将给水厂污泥用于水体污染物去除,为给水厂污泥的资源化和水污染控制提供了双赢的思路。该文总结了水厂污泥的性质和作为吸附剂对水体中磷等污染物的吸附性能,对水厂污泥作为人工湿地、雨水生物滞留系统、土壤渗滤系统、绿色屋顶的基质及湖泊底泥覆盖剂的研究进展进行了综述,探讨了给水厂污泥资源化利用的环境风险问题,为水厂污泥净化水体污染物的应用研究提供参考。
With excellent and stable adsorption capacity for water contaminants, water treatment residual（WTR） has great application potential in water purification. WTR’s application in the field of water purification provides a win-win idea for water treatment techniques and WTR recycling. This article summarized the characteristics of WTR and its adsorption capacity for water contaminants such as phosphorus and fluoride. The research progress of WTR as media of wetland, bioretention,subsurface infiltration system, green roof and covering agent of lake sediment was reviewed. The environmental risk of WTR’s reclamation and recycling was discussed aiming to provide reference for further research and development of WTR’s application for water purification.
