摘要：

Acrylic fiber wastewater from acrylic plant was used as feedstock, the feasibility of treatment high concentration organic wastewater by combination method of flocculation and adsorption was investigated through single factor experiment and orthogonal experiment. Experiment results showed that positive ion polyacrylamide presented the best flocculation effect in the experiment of treatment acrylic fiber wastewater by single flocculant. The flocculating effect was improved remarkably by multi-step flocculation and adsorption, and the removal effect of turbidity and COD was increased. The optimum combination order was positive ion polyacrylamide, the polymerization aluminum chloride and the shell polyose, and the removal efficiency of turbidity and COD can reach above 90% and 70.5% after treatment acrylic fiber wastewater by the combination of flocculation and adsorption, respectively.
