摘要:
再生水是城市水体的重要补充水源，其中所含的溶解性有机物（DOM）以难降解有机物为主，易造成受纳水体的污染，且夏季尤为严重。以完全受再生水补充的圆明园景观水体为研究对象，利用化学检测和光谱学方法分析各项特征指数，对夏季再生水回用过程中有机物的空间变化规律与主要来源进行研究。结果显示，研究区域内水体的COD浓度呈现西低东高的分布规律，且在宽阔和相对封闭水域呈现富集、累积的特点。水生植物修复区域对COD有明显的降解作用，平均降解率为27.28%。水体中的主要有机组分包括类色氨酸、类腐殖质和类酪氨酸三类，DOM的主要来源是生物源，与再生水回用过程中的微生物代谢产物及水体中植物和微生物的代谢活动有关。相关性分析结果显示，COD与类酪氨酸的相关性较高，说明有机物超标问题是由难降解有机物的累积作用造成的；另外，COD与水生植物覆盖密度呈负相关关系，说明水生植物及其周围的微生物对COD的降解有积极作用。
Abstract:
Reclaimed water is a crucial supplementary source for urban water bodies. The dissolved organic matter (DOM) it contains is primarily composed of refractory organic compounds, which can lead to pollution of the receiving water bodies, especially during summer. This study investigated the Yuanmingyuan landscape water body, which is entirely replenished by reclaimed water. Chemical analysis and spectroscopic methods were employed to examine characteristic indices, aiming to understand the spatial distribution patterns and primary sources of organic matter during reclaimed water reuse in summer. The results showed that the COD concentration within the study area followed a distribution pattern of lower values in the west and higher values in the east, with enrichment and accumulation occurring in both broad and relatively enclosed water areas. The aquatic phytoremediation zones demonstrated a clear degradative effect on COD, with an average degradation rate of 27.28%. The main organic components in the water body included tryptophan-like, humic-like, and tyrosine-like substances. The primary source of DOM was biological, associated with microbial metabolites from the reclaimed water reuse process as well as the metabolic activities of plants and microorganisms within the water body. Correlation analysis revealed a strong positive correlation between COD and tyrosine-like substances, indicating that the organic matter exceedance was caused by the accumulation of refractory organic compounds. Additionally, COD showed a negative correlation with aquatic plant coverage density, suggesting that aquatic plants and their associated microorganisms played a positive role in COD degradation.
