钢渣处理碱性品红染料废水的实验研究

摘要

以钢渣为吸附剂,应用于去除模拟废水中的碱性品红,探讨了钢渣粒径、吸附时间、吸附剂用量、转速、温度对吸附效率的影响.结果表明:钢渣对碱性品红有较好的脱色效果,对于100mL100mg/L的模拟碱性品红废水,投加1g100目的钢渣,在室温,150r/min,振荡45min的条件下,脱色率可达98％以上.%Basic fuchsin Wastewater were treated by steel flag. The influence of adsorbent size, adsorption time, adsorbent dose, and temperature on the removal rate were discussed. The results showed that steel slags have high decolouring effect on basic fuchsin.At room temperature, decolouring rate can exceed 98% for 100ml of l00mg/L basic fuchsin wastewaer when adding 100 mesh lg steel slag and oscillating for 45 minutes.
