Research progress on removal of phosphate from aqueous solution by biochar and its metal modified materials

    Corresponding author: WANG Feng, wangfeng_530@163.com
  • Fund Project: Supported by the National Basic Research Program of China(2017YFD0800403), the National Foundation of Tianjin(16JCYBJC29700)and the Financial Projects of the Ministry of Agriculture and Rural Areas(22110402001006).
  • 摘要: 磷素是水体富营养化主要限制性因子,控制河流湖泊中磷酸盐具有重要意义.吸附法是一种经济、高效和操作简单的除磷方法,但其应用的关键在于选择合适的吸附材料.将生物炭应用于水体磷酸盐脱除,一方面可为农林废弃物、畜禽粪便、活性污泥、入侵植物的处理提供新途径,另一方面吸磷后的生物炭还能用于土壤改良.然而,生物炭脱除水体磷酸盐虽具有以上优势,但也存在实际应用困难的问题.回顾了国内外生物炭脱除磷酸盐的相关研究成果.总结了生物炭脱除磷酸盐的能力;解释了常规生物炭和金属改性生物炭的脱磷机理;分析了溶液pH值、温度、共存离子、初始磷酸盐浓度以及其他反应条件对生物炭脱除磷酸盐的影响,简述了生物炭解吸磷酸盐的特性.最后提出应深入研究生物炭金属改性机理和脱除磷酸盐的机理,开展生物炭吸附磷素形态组成复杂的自然水体或吸附柱试验,加强吸磷生物炭用作土壤改良的研究及风险评价,并对生物炭制造成本做出估算,争取早日实现生物炭污染水体脱磷的产业化应用.

摘要: 磷素是水体富营养化主要限制性因子,控制河流湖泊中磷酸盐具有重要意义.吸附法是一种经济、高效和操作简单的除磷方法,但其应用的关键在于选择合适的吸附材料.将生物炭应用于水体磷酸盐脱除,一方面可为农林废弃物、畜禽粪便、活性污泥、入侵植物的处理提供新途径,另一方面吸磷后的生物炭还能用于土壤改良.然而,生物炭脱除水体磷酸盐虽具有以上优势,但也存在实际应用困难的问题.回顾了国内外生物炭脱除磷酸盐的相关研究成果.总结了生物炭脱除磷酸盐的能力;解释了常规生物炭和金属改性生物炭的脱磷机理;分析了溶液pH值、温度、共存离子、初始磷酸盐浓度以及其他反应条件对生物炭脱除磷酸盐的影响,简述了生物炭解吸磷酸盐的特性.最后提出应深入研究生物炭金属改性机理和脱除磷酸盐的机理,开展生物炭吸附磷素形态组成复杂的自然水体或吸附柱试验,加强吸磷生物炭用作土壤改良的研究及风险评价,并对生物炭制造成本做出估算,争取早日实现生物炭污染水体脱磷的产业化应用.
