【摘要】 研究了强磁粉(Fe3O4)与无机混凝剂Al2(SO4)3在垃圾渗滤液处理中的协同作用。结果表明:Fe3O4与Al2(SO4)3复合使用混凝效果优于单纯使用Al2(SO4)3的混凝效果。当Al2(SO4)32.0g/L,磁粉(Fe3O4)1.6g/L,搅拌强度150r/min,pH值3.0,沉降时间5min时,可使渗滤液的COD去除率达70%,混凝时的胶粒沉降速率明显加快。更多还原

【Abstract】 The cooperation function of high magnetic powder（Fe₃O₄）and abio-coagulant Al₂（SO₄）₃ were studied in this paper.The result indicated that the flocculation effect from complex use of Fe₃O₄ and Al₂（SO₄）₃ was better than use of Al₂（SO₄）₃ only.When dosage of Al₂（SO₄）₃ is 2.0 g/L,Fe₃O₄ is 1.6 g/L,stirring rate is 150 rpm,pH is 3.0,sedimentation time is 5 min,the COD removal rate of leachate is 70%.The sedimentation velocity of colloidal particle is picked up evidently in flocculation.更多还原
