制备镁铁复合絮凝剂(PMFS),研究其对近岸海水的处理效果,考察了PMFS在絮凝过程聚集状态以及投加量、p H等因素对污染物去除效果的影响。结果表明:PMFS絮凝过程是多种机制共同起作用的动态变化过程,形成絮体沉降性能良好;PMFS絮凝性能略优于聚合硫酸铁(PFS);浊度、溶解性有机碳(DOC)去除率和总磷(TP)去除率分别达到96%、45%和92%;p H对海水的浊度去除影响较小,但酸性条件下更利于DOC和TP的去除。 (PMFS) was prepared to study its treatment effect on coastal seawater. The effect of PMFS on the pollutant removal efficiency was investigated in the flocculation process and the dosage, p H and other factors. The results show that the flocculation process of PMFS is a dynamic process that many kinds of mechanisms work together to form flocs. The flocculation performance of PMFS is slightly better than that of PFS. The turbidity, dissolved organic carbon (DOC) removal rate And total phosphorus (TP) removal rates reached 96%, 45% and 92% respectively. However, p H had little effect on the turbidity removal of seawater, but was more conducive to the removal of DOC and TP under acidic conditions.
