光照周期对藻菌颗粒污泥系统处理含NMP废水的效能影响研究
Research on the Effect of Photoperiod on the Treatment Efficiency of NMP-Containing Wastewater by Algal-Bacterial Granular Sludge System
摘要: 为应对传统处理方法处理含N-甲基-2-吡咯烷酮(NMP)的废水的局限性，本研究利用藻菌颗粒污泥系统(ABGS)，以1000 mg/L NMP为处理对象，通过序批式和半连续流实验，系统探究全光照(24 h/0h)与光暗交替(12 h/12h)两种光照周期对ABGS处理NMP废水效能的影响。结果表明，光暗交替条件表现出更好的脱氮性能，大幅提升了TN去除率，有效降低了氨氮积累。同时光暗交替显著提升原核生物群落多样性与结构稳定性，Bacteroidota、Acidobacteriota等脱氮和难降解有机物降解功能菌丰度上升，真核生物则更适应全光照环境。本研究证实12 h/12h光暗交替有助于提升ABGS的脱氮效能，为高浓度NMP工业废水的绿色低碳处理提供了实验依据。
Abstract: To address the limitations of traditional methods in treating wastewater containing N-methyl-2-pyrrolidone (NMP), this study employed an algal-bacterial granular sludge (ABGS) system to treat 1000 mg/L NMP. Through batch and semi-continuous flow experiments, the effects of two photoperiods—continuous light (24 h/0h) and light-dark alternation (12 h/12h)—on the treatment efficiency of NMP-containing wastewater by the ABGS system were systematically investigated. The results showed that the light-dark alternation condition exhibited superior nitrogen removal performance, significantly enhancing the total nitrogen (TN) removal efficiency and effectively reducing ammonia nitrogen accumulation. Simultaneously, light-dark alternation markedly improved the diversity and structural stability of the prokaryotic community, with increased abundance of functional bacteria involved in nitrogen removal and degradation of refractory organic compounds, such as Bacteroidota and Acidobacteriota. In contrast, eukaryotic organisms were better adapted to the continuous light environment. This study confirms that a 12 h/12h light-dark alternation helps enhance the nitrogen removal performance of ABGS, providing experimental evidence for the green and low-carbon treatment of high-concentration NMP industrial wastewater.
