摘要
为了降低水体富营养化,以粉煤灰作为吸附剂,探讨了含磷为50～120mg/L模拟废水脱磷的一般规律。结果表明,粉煤灰是一种有效的吸附剂,在含P浓度为50～120mg/L,粉煤灰用量每50mL为2～2.5g,粒径范围140～160目,pH中性的实验条件下,磷的去除率最高可达99％以上。
To lower the trend of serious eutrophication of reserviors, this paper studied the ability of fly ash to remove phosphorus from wastewater. The results showed that fly ash is effective to adsorb phosphorus. When concentration of phosphorus was 50 ~ 120mg/L, amount of fly ash used 2 ~ 2.5g and partide size 140 - 160 mesh, under pH neutral experimental condition, the efficiency of phosphorus removal rate reached about 99%.
