为应对可能出现的污染事件,模拟水厂的工艺流程,探讨了聚合硫酸铁应急处理源水镍污染的方法。结果表明,混凝剂聚合硫酸铁的投加量为20 mg/L、助凝剂PAM的投加量为0.5mg/L,调节p H值为9.2,混凝沉淀后再经砂滤处理,对镍的去除率达到88.2%~90.1%,出水水质达到《生活饮用水卫生标准》(GB 5749—2006)的要求。在不需要回调p H值的前提下,最大处理能力达到0.25 mg/L。 In order to deal with possible pollution incidents, the process of the water plant was simulated, and the pollution of nickel from the source water by the polymerization ferric sulfate was discussed. The results showed that the dosage of coagulant polyferric sulfate was 20 mg / L, the dosage of coagulant PAM was 0.5 mg / L, the value of p H was adjusted to 9.2. After coagulation and sedimentation, Nickel removal rate of 88.2% to 90.1%, effluent quality to “drinking water health standards” (GB 5749-2006) requirements. Without the need for callback p H value under the premise of the maximum processing capacity of 0.25 mg / L.
