摘要
基于非金属矿物材料泥炭空隙率大、比表面积大、吸附能力强、分子结构中存在多种活性官能团,以及具有较强的离子交换和络合能力等特点,探讨泥炭在水处理中除磷的机理,分析水处理中采用泥炭、改性泥炭除磷的研究进展,为泥炭、改性泥炭及生物膜形成后的再生泥炭在水处理中的应用提供理论和技术支撑。
Peat is a non-metallic mineral material which has a high porosity, a large specific surface, a high adsorptive power, a molecular structure with many kind of active functional groups, and a high ion-exchange and complexing power. In this paper, mechanisms of phosphorus removal by peat for water treatment was discussed. Investigations on phosphorus removal by peat and modified peat were reviewed. This work will provide theoretical and technical supports for application of peat, modified peat and bioregeneration to water treatment.
