摘要
利用硫酸亚铁、聚合氯化铝(PAC)和聚丙烯酰胺(PAM)混凝沉淀,对鄂尔多斯羊绒集团废水进行除硫、脱色处理,通过正交试验确定了混凝剂的最佳投加量:FeSO_4·7H_2O为100 mg/L,PAC为75 mg/L,PAM为2mg/L,最佳pH值为7.5。并对次氟酸钠的脱色效果进行了研究,认为将二者结合使用可以达到更好的脱色效果。
Eliminating sulfide and decolorizing for wastewater from Erdos Group was done by the coagulating sedimentation using FeSO4, PAC and PAM. Through the orthogonal experiment, the best process conditions are ascertained, which are the dosage of FeSO4.· 7H2O 100 mg/L, PAC 75 mg/L, PAM 2 mg/L, and pH 7.5. In addition, the efficiency of NaClO used in decolorization is researched. The result shows that the better effect can be acquired by the coagulating sedimentation combining with NaClO.
