中文摘要：
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 1〉FAB 3〉FAB 2,FAB 1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相关性关系,根据FAB组成成分和反应结果可以推断磷的去除是吸附和沉淀反应协同作用的结果。此外,FAB 3较小的容重和孔洞结构增大了与磷酸盐的接触表面,使得FAB 3相对于FAB 1、FAB 2能更快地达到浓度平衡。
英文摘要：
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-structural aspect. In the microstructural aspects experiment, the general removing effects were FAB - 1 〉 FAB - 3 〉 FAB - 2, with the removing effect of FAB - 1 as 90. 1% when its adding dosage is 10. 0 g. Other reactional conditions being equal, the phosphorous-removing effect was in negative correlation with the FAB diameters and initial concentration of phosphate. According to the components and reactional results of FAB, it could be concluded that the removal was a consequence under the cooperative function of sedimentation and adsorption. Besides, the smaller bulk density and pore structure enlarged the contacting surface with phosphate, which enabled FAB - 3 to achieve the concentration balance at a comparatively more rapid rate than FAB - 1 and FAB - 2.
