摘要

We studied a novel bioflocculant poly(γ-glutamic acid)(PGA). With the addition of 4mg/L PGA (Mw=9×10~5Da)and 12 Mm CaCl_2, the optimal temperature for flocculation performance of PGA in the kaolin suspension was about 30°C, giving the highest flocculating activity of 98%, respectively. Studies of the flocculating properties revealed that it was stable at 30-90°C and pH 7-11. With treatment of jean dyeing wastewater flocculation, PGA showed that the color, COD, NH_3-N, alkalinity and hardness removal ratios were 90%, 91.7%, 73.3%, 65% and 86%, respectively. Bioflocculant PGA may find possible application as an alternative for textile dyeing industry and environmental bioremediation.
