摘　　要：采用钢渣和改性钢渣为吸附剂,处理模拟酸性大红废水,探讨了钢渣粒径、吸附时间、吸附剂用量对酸性大红去除率的影响。结果表明:钢渣粒径、吸附时间、吸附剂用量对酸性大红去除率均有影响;经过简单预处理的钢渣对酸性大红的去除效果很差,对于100mL质量浓度为100mg/L的酸性大红溶液,投加80目钢渣3g,振荡40min,最高去除率为12%;经过碱改性的钢渣,对酸性大红的去除率显著提高,最高去除率可达52.5%,比同等条件下用钢渣处理酸性大红废水,去除率提高了40%。Using steel slag and modified steel slag as adsorbent to treat simulant acid brilliant scarlet dye wastewater, the influence of grain size of steel slag, adsorption time, adsorbent dosage on removal rate of acid brilliant scarlet were discussed. The results showed that： all the above factors could affect the removal rate of acid brilliant scarlet; however, the removal effect of it by simply pretreated steel slag was poor. For the 100 mL acid brilliant scarlet solution with mass concentration of 100 mg/L, when the dosage of steel slag（over 80 mesh） was 3 g, the oscillation time was 40 min, the maximal removal rate of acid brilliant scarlet was 12%; through the alkali modification, the performance of steel slag on acid brilliant scarlet removal was improved significantly, using the modified steel slag to treat the said solution under the same condition mentioned above, the maximal removal rate of acid brilliant scarlet reached 52.5%, which was increased by 40%.
