煤渣复合混凝剂去除溶解态多核芳香烃及机理的研究
Study on the Mechanism for Removing PAHs from Coal Tar Processing Wastewater by Coagulation
-
摘要: 比较了Ca(OH)2、Ca(OH)2+Fe2(SO4)3、硅藻土和煤渣与聚丙烯酰胺(PAM)组成的复合混凝剂,对焦油加工过程废水中的多环芳烃的处理效果。Abstract: The complex coagulant composed of coal cinder and PAM can remove PAHs from coal tar processing wastewater efficiently, and the removal of naphthalene is more than 40%. This indicates that the method of adding material to increase turbidity of wastewater can remove the dissolved PAHs. Factors influencing removal and the mechanism for removing PAHs by coaguation are discussed.
