Abstract
这研究的目的是由外部碳来源的增加调查 denitrification potentialenhancement 并且用率(NUR ) 批测试的硝酸盐利用估计 denitrification 潜力 forthe predenitrification 系统。它被看 thatthe denitrification 潜力能实质地与三 externalcarbon 来源的增加被增加,即分别地,甲醇,乙醇,和醋酸盐,和乙醇,醋酸盐,和甲醇的 denitrification 率到达了直到 9.6,12 ,和 3.2 mgN/( g VSS-h )当那 ofstarch 废水仅仅是 0.74 mgN/( g VSS-h )时。由比较,乙醇被发现是 bestexternal 碳来源。有淀粉废水和浪费乙醇的 NUR 批测试是潜力由于 NUR 测试,废水特征和运动参数的浪费乙醇 addition.By 工具从 5.6~16.5 mg NO3-N/L 增加了的带的 out.The denitrification 能被估计,它被用来决定废水的 denitrification 潜力,计算植物的 thedenitrification 潜力并且预言硝酸盐自河质量,也为开发碳剂量控制 st 的 asprovide 信息
