摘要
采用硫酸、高分子絮凝剂聚二甲基二烯丙基氯化铵(PDMDAAC)和阳离子型聚季铵盐对沸石进行改性,考察了改性沸石投量、pH值、吸附时间对处理效果的影响。结果表明:改性沸石用量为6g/L、pH值为7、吸附时间100min、反应温度为20℃,废水中磷的去除率可达98%以上。
Zeolite was modified by macromolecular flocculant PDMDAAC、cationic polyquaternium（BT-3） and sulphuric acid.The effect of the dosage of modified zeolite,pH and the contacting time for dyeing wastewater were investigated.The results showed that the removal rate of arsenic can be over 98% with pH value 7,the dosage of modified zeolite was 6g/L and the adsorption time was 100min,reaction temperature was 20℃.
