粉煤灰砖颗粒沉淀与吸附协同作用去除水体中的磷OACSTPCD
Combined Effect of Sedimentation and Adsorption of Granular Fly-Ash Brick on Phosphorus Removal in Water
以建筑废弃物粉煤灰砖块为原料,经破碎、筛分成不同粒径制备粉煤灰砖颗粒(简称FAB),研究了三种不同厂家的粉煤灰砖对水体中磷的去除效率.成分分析结果显示相对于粉煤灰原灰,FAB中钙氧化物含量均有所提高,TEM结果显示FAB表面微观形貌凹凸不平、层次多样.在除磷实验中,总体上磷去除效率为FAB-l＞FAB-3＞FAB-2,FAB-l在投加量为10.0 g时磷去除率为90.7％.在其他反应条件相同情况下,水体中磷去除率与FAB粒径和磷酸盐初始浓度均呈负…查看全部>>
From the granular fly-ash brick,a kind of construction garbage,particles of fly-ash brick (short for FAB) with different sphere diameters were made through crushing and sorting,so as to study on phosphorous removal effects of fly-ash brick made by three different factories.The component analysis showed that as to the raw materials of fly-ash,the calcium-oxides content of FAB increases and the TEM result displayed an uneven and multi-leveled surface micro-str…查看全部>>
