| Abstract: | This article dealed with the influencing factors and the optimum treating condition of the starch wastewater with high relative molecular poly(sodium acrylate). It has been found that those factor, including the dose of flocculant and aid-flocculant, pH of wastewater, agitation speed, agitation time, etc, have significant effect on the COD and the turbidity removal. The results showed COD removal rate was no less than 50%, turbidity removal rate more than 90%, while using sodium acrylate-acryamide copolymer as flocculant and CaCl2 as aid-flocculant. The flocculate is nonpoisonous and can be recycled. |
| Keywords: | high relative molecular poly(sodium acrylate) focculant starch wastewater |
