Abstract:
Adsorption is widely used in aqueous defluorination.If the industrial and agricultural wastes are used as the adsorbent of fluoride,their pollution to the environment can be reduced and the cost of defluorination decreased as well.The research of application of industrial wastes（such as brick powder,red mud and fly ash） and agricultural wastes （such as bamboo,straw and cashew nut sheath） to aqueous defluorination is summarized.Thereafter,the trends and future use of the industrial and agricultural wastes for defluorination are predicted.The method of pre-treatment and disposal,as well as the fundamental research on the industrialization of the applied theory are put forward,so as to make the economic and highly efficient treatment technology be applied to water treatment in large-scale earlier.

摘要：
吸附法是水溶液除氟应用最广泛的方法,将工农业废弃物作为除氟吸附剂可减少废弃物对环境的污染,降低除氟成本。作者基于对国内外砖粉、红泥、粉煤灰等工业废弃物及竹炭、稻草、果皮等农业废弃物及其制品用于水溶液除氟研究现状,提出废弃物制吸附剂除氟的后续研究应侧重预处理和使用后的处置方法,以及工业化应用理论基础研究,以寻求经济、高效的治理工艺,早日大规模应用于水处理中。
