以改性聚合硫酸铁(MPFS)为混凝剂,对微污染水源水中微量Pb~(2+)的去除进行了研究.考察了水的pH值、MPFS投加量、Pb~(2+)初始浓度和源水浊度等因素对Pb~(2+)去除的影响.结果表明,在pH>6的条件下,当源水中Pb~(2+)浓度为0.1mg/L时,投加3.00mg/L的MPFS(以Fe计),可使水中Pb~(2-)的去除率达到90%以上,满足生活饮用水水质指标;当水中Pb~(2+)初始浓度较高时,适当增加MPFS投加量,即可使Pb~(2+)得到有效去除.

The removal of lead from micro-polluted waters by modified polyferric sulfate(MPFS) was studied. Effects of the pH, the dosage of MPFS, the concentration of lead ion and the turbidity of raw water on the lead removal were investigated. Under the condition of pH>6, the removal efficiency of lead was more than 90% when dosage of MPFS was 3.00mg/L and lead concentration 0.1mg/L in raw water. When the concentration of lead was higher than 0.1 mg/L in raw water, lead could also be removed under the condition of increasing the dosage of MPFS.
