| 摘 要： | 采用慢速滴碱法制备了复合絮凝剂APAC,研究了处理条件对APAC去除废水中Ni2+及浊度效果的影响,探讨了APAC去除废水中Ni2+和浊度的净化机理.结果表明:APAC对Ni2+有很好的去除能力,去除率最高可达87.42%;废水的pH值越高,Ni2+的去除率越大;APAC中凹凸棒组分在一定程度上促进了Ni2+的去除;当铝与凹凸棒质量比为2:1,盐基度为80%,APAC投加量为32 mg/L,pH值在7～12时,APAC对废水中Ni2+和浊度的去除效果最佳.

| Abstract: | A novel composite tlocculant,APAC,was prepared in the presence of polyaluminum chloride via low-speed alkaline titrimetry,where attapulgite modified with HCl was used as the main raw material.The flocculantion mechanism of APAC was discussed in relation to its action in removing Ni2+ and decreasing turbidity.And some factors affecting the removal of Ni2 + and decrease of turbidity were also studied.Results show that APAC has strong capability for re-moving Ni2+,and the highest removal rate of 87.42% for Ni2... |
