摘　　要：对 Pullulan处理养猪场污水进行了研究 .结果表明 :污水的稀释倍数与 Pullulan的添加量对处理效果有极显著的影响 ,当 Pullulan在 2倍稀释污水中的添加量达到 3mg/ kg时 ,污水的 BOD、COD、总 P、N的去除率达到 90 %以上 ;大肠杆菌的去除率达到 95 %以上 ,透过率也从 8%上升到 92 % .Treatment of wastewater from pig breading farm using pullulan was studied. Results showed that the treatment effects were noticeably affected by dilution times of wastewater and amount of pullulan added. The COD and BOD were reduced by more than 90%, total phosphorus and nitrogen by more than 90%, transmission increased from 8% to 92%, and more than 95% of E. Coli were eliminated when the wastewater was diluted by 2 times and pullulan added in the water was 3 mg/kg.
