稻麦草类碱木素混凝剂的性质及其应用
- NATURE OF STRAW PULPING LIGNIN AS COAGULANT AND ITS APPLICATION
- 摘要：胶体化学性质研究表明,稻麦草类碱木素是一种具有多种活性官能团的阴离子型高分子混凝剂。絮体呈片层状和卷筒状,在其沉降过程中对水中胶粒产生网捕、卷扫作用。用这类木素混凝剂可回收酸性酿造废液中的菌体蛋白,对染料废水也有较好的处理效果。
- Abstract：The study on the colloidal chemical nature of straw pulping lignin shows that lignin is a kind of anion macromolecular coagulant with many active function groups.Microscopic observations demonstrate that lignin flocs are leaf and tile like which can trap and sweep the colloidal particles for sedimentation.It is proved that lignin coagulant is effective for treatment of acidic waste liquors from fermentation,dye stuff and other industries with high removal rate of suspended solids,color and COD.
- Key words：lignin coagulant monosodium glutamate wastewater dyeing production wastewater sweeping trapping.
