摘要
磷是导致水体富营养化的主要驱动因素,由于工业和农业活动导致过量磷酸盐排放到水体中,富营养化现象已成为全球性的环境问题.工业固体废弃物含有易与磷酸盐结合的氧化态/离子态金属(Al、Fe、Ca、La和Ce等),利用工业固体废弃物控制磷污染是一种实现循环经济的策略.本文总结了 5种工业固体废弃物(给水处理残渣(DWTR)、粉煤灰(CFA)、赤泥(RM)、碱性氧气转炉炉渣(BOF-炉渣)和流化催化裂解废催化剂(SFCC-催化剂)控制磷污染的研究进展,主要包括材料的吸附性能、改性和制粒方法、影响因素,以及金属浸出问题和应对措施.
Abstract
Phosphorus is the main driver of eutrophic water bodies.Eutrophication has become a global environmental problem due to excessive phosphate discharged into water by industrial and agricultural activities.Industrial solid waste contains oxidized/ionic metals(Al,Fe,Ca,La and Ce,etc.)that are easily combined with phosphate.Using industrial solid waste to control phosphorus pollution is a strategy to achieve circular economy.The research progress of five industrial solid wastes(drinking water treatment residue(DWTR),coal fly ash(CFA),red mud(RM),basic oxygen furnace slag(BOF-slag)and spent fluid catalytic cracking catalyst(SFCC-catalyst))in controlling phosphorus pollution were summarized in this paper,including adsorption performance,modification and granulation methods,influencing factors,metal leaching problems and counter measures.
