| 摘 要： | 通过单因素和正交实验优化马铃薯淀粉废水中培养絮凝复合菌的最佳营养条件,并利用响应面法优化所培养的絮凝复合菌处理马铃薯淀粉废水的最佳工艺条件。实验结果表明,马铃薯淀粉废水培养絮凝复合菌的最优条件为乙醇1.5m L/100m L、NH4NO30.15g/100m L、KH2PO40.35g/100m L、p H7.0;利用上述培养的絮凝复合菌处理马铃薯淀粉废水得到最佳工艺条件为复合菌投加量1m L/100m L、Ca Cl2投加量2m L/100m L、搅拌速度187r/min,此条件下马铃薯淀粉废水的化学需氧量(COD)去除率实际值达到89.10%,可回收粗蛋白物质6.23g/L作为动物蛋白饲料添加剂。

| Abstract: | In potato starch wastewater the optimistic nutrition conditions of flocculating- complex strains were optimized by single factors and orthogonal test, then the optimistic parameters of wastewater technology treated by these flocculating- complex strains were optimized by response surface methodology.The results indicated that the optimal nutrition conditions of cultured these strains was alcohol 1.5m L /100 m L, NH4NO30.15 g /100 m L, KH2PO40.35 g /100 m L and p H7.0, and the optimal parameters of wastewater technology treated by above flocculating-complex strains were strain dosages 1m L /100 m L, Ca Cl2 dosages 2m L /100 m L, stirring speed 187 r / min.Under these conditions the real chemical oxygen demand ( COD) removal rate of potato starch wastewater was 89.10%.Meanwhile the crude protein of 6.23 g / L was recovered and used as animal feedstuff additives. |
