摘要
通过试验,研究了钢渣对废水中磷的去除。探讨了影响其除磷因素如pH、反应时间、钢渣粒径、钢渣用量、磷的初始浓度等。研究表明,在pH=7,小于74μm的钢渣用量为0.5g,反应120min时废水中磷的去除率达90%以上,效果十分明显。
This paper studied phosphorus removal from the wastewater by steel slag,and discussed the influence factors of phosphorus removal such as pH,reactor time,steel slag paramenters,steel slag dosage,and the initial concentration of phosphours.The results showed that when pH was 7,the weight of steel slag with the diameter of less than 74 μm was 0.5 g,reactor time was 120 min,the removal rate of phosphorus was higher than 90%.The steel slag had a strong removing ability of phosphorus from the wastewater.
