Recent advancements in constructed wetlands(CWs)have highlighted the imperative of enhancing nitrogen(N)removal ***,the variability in influent substrate concentrations presents a challenge in optimizing N removal strategies due to its impact on removal efficiency and *** we show the interplay between influent substrate concentration and N removal processes within integrated vertical-flow constructed wetlands(IVFCWs),using wastewaters enriched with NO_(3)^(-)-N and NH4þ-N at varying carbon to nitrogen(C/N)ratios(1,3,and 6).In the NO_(3)^(-)-N enriched systems,a positive correlation was observed between the C/N ratio and total nitrogen(TN)removal efficiency,which markedly increased from 13.46±2.23%to 87.00±2.37%as the C/N ratio escalated from 1 to ***,in NH4þ-N enriched systems,TN removal efficiencies in the A-6 setup(33.69±4.83%)were marginally 1.25 to 1.29 times higher than those in A-3 and A-1 systems,attributed to constraints in dissolved oxygen(DO)levels and *** community analysis and metabolic pathway assessment revealed that anaerobic denitrification,microbial N assimilation,and dissimilatory nitrate reduction to ammonium(DNRA)predominated in NO_(3)^(-)-N systems with higher C/N ratios(C/N 3).In contrast,aerobic denitrification and microbial N assimilation were the primary pathways in NH4þ-N systems and low C/N NO_(3)^(-)-N systems.A mass balance approach indicated denitrification and microbial N assimilation contributed 4.12-47.12%and 8.51e38.96%in NO_(3)^(-)-N systems,respectively,and 0.55e17.35%and 7.83e33.55%in NH4þ-N systems to TN *** enhance N removal,strategies for NO_(3)-N dominated systems should address carbon source limitations and electron competition between denitrification and DNRA processes,while NH4þ-N dominated systems require optimization of carbon utilization pathways,and ensuring adequate DO and alkalinity supply.

学校文化建设是我国文化强国战略的重要组成部分。当前,我国学校文化建设正遭遇着由系统殖民引起的离境之忧、主体中心逻辑造就的生成之困和从“成人”到“治人”的体用之殇。哈贝马斯交往行动理论为重塑学校文化生态提供了有益启示。其主要观点将以语言为媒介的交互活动作为系统进化的动力源泉,将“U”“D”原则作为系统优化的外部保障,将“非强迫共识”作为系统规范的本质属性。基于此提出我国学校文化建设的变革路径,要强化其底层逻辑,完善其对话规则,遵循其人本指向。
