The Use Effect of Reed Ethanol Lignin Flocculant
The synthetic of lignin flocculant has two steps. First, the graft copolymerization of lignin and acrylamide; Second, make the graft copolymer into cation product. This lignin flocculant has a high decolour rate and removal of CODCr . Under the experimental conditions which pH is 6.0～8.0, 0.5mL lignin flocculant and 50mL waste water, decolour rate is high to more than 80.0%, removal of CODCr could reach 85.0%.
