Abstract

The impact of wastewater on the ecological functioning of constructed wetland systems can be assessed by analyzing the microbial diversity, profiling, and community structure of soils irrigated with wastewater. In this study, we utilized in situ, culture-independent 16S rRNA sequencing technology to comprehensively investigate the biodiversity, abundance, and structure of bacterial communities in reed field soils irrigated with pretreated pulp and paper wastewater (PPW) and freshwater. Our results revealed significant differences in bacterial communities across freshwater-irrigated wetlands, short-term wastewater-irrigated wetlands, and long-term wastewater-irrigated wetlands. Redundancy analysis and Spearman's correlation analysis demonstrated that soil pollutants (TX and AOX), nutrients (TN and TP), and heavy metals significantly influenced the microbial community structure. These findings underscore the importance of microbial monitoring and suggest that irrigation should be discontinued after 10 years to facilitate the recovery of wetland ecosystems.

通过分析用废水灌溉的土壤中的微生物多样性、剖面和群落结构，可以评估废水对人工湿地系统生态功能的影响。在这项研究中，我们利用原位、不依赖培养的 16S rRNA 测序技术，全面研究了用预处理过的纸浆和造纸废水（PPW）和淡水灌溉的芦苇田土壤中细菌群落的生物多样性、丰度和结构。结果显示，淡水灌溉湿地、短期废水灌溉湿地和长期废水灌溉湿地的细菌群落存在明显差异。冗余分析和斯皮尔曼相关分析表明，土壤污染物（TX 和 AOX）、养分（TN 和 TP）和重金属对微生物群落结构有显著影响。这些发现强调了微生物监测的重要性，并建议在 10 年后停止灌溉，以促进湿地生态系统的恢复。
