| 摘 要： | 文章利用高密度澄清池对无机絮凝剂和有机絮凝剂在海水体系中的絮凝效能进行了综合评价.研究结果表明,海水预处理过程中使用无机低分子絮凝剂,药剂投加量较大.与无机低分子絮凝剂相比,无机高分子絮凝剂用于海水净化过程中,投剂量减半,铁盐的混凝效果略优于铝盐,但差别不大.无机高分子絮凝剂的制备工艺非常重要,不同的制备工艺导致产品的碱化度和聚合度不同,使得同类产品的絮凝效果产生了很大差异.有机高分子絮凝剂单独处理海水时,存在着随投剂量增大,胶体出现再稳定现象.

| Abstract: | Performance evaluation for inorganic and organic flocculant's coagulation efficiency in seawater system was made by using high-density clarifier.It took a large dosage of traditional inorganic flocculants to remove the turbidity of seawater.Compared with the inorganic flocculants,the dosage of inorganic polymer flocculants in seawater purification process was halving.The coagulation effect of polyferric salt was a little better than that of polyaluminous salt.The preparation technics of inorganic polymer fl... |
