摘要：
以无紫外辐照的生物膜反应阶段（B）为对照组，研究了紫外辐照协同生物膜反应阶段（UV/B）去除尾水中的总氮特性，考察尾水中氮素污染物转化规律和影响因素。试验结果表明：UV/B对TN、NO3--N、NH4+-N、COD、BOD的平均去除率比B要分别高出9.1%、5.9%、14.2%、3.0%、17.9%，紫外辐照有利于强化生物膜反应器脱氮和COD去除效果，可以为尾水深度脱氮和COD去除提供借鉴。

Abstract:
Taking a biofilm reactor without ultraviolet irradiation(B) as control, the efficiency of total nitrogen(TN) removal from effluent by an enhanced biofilm reactor under ultraviolet irradiation(UV/B) and the transformation law and influencing factors of nitrogen pollutants in tail water were investigated. The experimental results indicated that the averaged removal rate of TN, NO3--N, NH4+-N, COD and BOD of UV/B was higher 9.1%, 5.9%, 14.2%, 3.0%, 17.9% than those of B. The ultraviolet irradiation is helpful for enhancing the nitrogen removal and COD removal efficiency, and the results can as a reference for nitrogen removal and COD removal from the effluent.
