摘要
在低温低浊条件下,研究了聚合硫酸铁(PFS)、硫酸铁(FS)、氯化铁(FC)、硫化钠、聚丙烯酰胺(PAM)等单一混凝剂以及经该5种混凝剂自由排列组合形成的二级复合混凝剂对锑的去除效果;选取硫化钠+PAM复合混凝剂,考察了pH、硫化钠投加量、PAM投加量及搅拌时间4个因素对锑去除效果的影响。以期为突发性锑污染事件的应急处置提供技术支持。
The antimony removal efficiency of PFS, FS, FC,Na2S,PAM and their pairwise coupling composite coagulants in water under low temperature,low turbidity conditions was investigated. The Na2S+PAM composite coagulant was selected, and the influence of pH,Na2S dosage,PAM dosage and mixing time on the antimony removal efficiency further investigated,with a view to provide technical support for the emergency treatment of antimony pollution incident.
