摘要
以含镍废水为处理对象,主要探讨了高分子重金属絮凝剂(MHMF)对废水中镍离子和浊度的去除效果。与无机絮凝剂Al2(SO4)3、PAC相比较,MHMF处理含镍废水具有投加药量少,最佳适用pH值低,形成絮体快而且个体较大,絮体沉降性能好、不易破碎等特点。在pH=5.5～6时镍的去除率达98％,浊度的去除率也在98％以上。尤其是在处理具有浊度的含镍废水过程中,镍离子和致浊物质可相互促进各自的去除。
In this paper, the removing effects on nickel ions and turbidity by Macromolecule Heavy Metal Flocculant(MHMF) was mainly discussed for the nickel wastewater treatmtne. MHMF are characterized by less flocculant input, lower value of the most suitable pH, higher velocity of floc formation and sedimentation, and the floc is not easer to break, etc, compared with inorganic flocculants such as Al2(SO4)3, PAC. When the pH ranged from 5. 5 to 6. 0, the removal rates of nickel and turbidity are 98% and above 98% respectively. The nickel ions and the substances causing turbidity could promot the removal of each other in the process of treating wastweater containing both nickel and the substances causing tru-bidity.
