摘要
研究了造粒粉煤灰的最大磷吸附量、磷吸附速率等吸附特征,以及颗粒粒径、磷浓度、水力负荷对景观水除磷效果的影响。还进行了为期21天的连续过滤试验,发现滤床在高水力负荷条件下能持续地去除景观水中的磷。
The maximum phosphorus adsorption capacity and adsorption rate of granulated fly ash were studied. The influence of granular diameter, phosphorus concentration, and the hydraulic loading rate were also studied. In column experiment during 21 days, it was observed that the granulated fly ash could continuously remove the phosphorus under high hydraulic loading rate.
