摘要:以华北地区某城市污水管道沉积底泥为研究对象，在分析底泥中碳、氮、磷和VSS/SS等常规污染物含量及其组分占比的基础上，探索城市污水管道沉积底泥污染物向上覆水溶出的条件及其碳源应用于污水处理的潜力。结果表明：污水管道沉积底泥污染物中碳、氮、磷含量较高，且具有高COD/TN、高COD/TP特征，比值分别达到37.8和180.4，且BOD5/TN和BOD5/TP分别达到8.4和40.3；适宜的搅拌-沉淀作用能够实现沉积底泥中可生物利用碳源的高效提取，同时上覆水中的BOD5/TN和BOD5/TP可分别提升至11.2和48.4，有机组分占比从35%提高至52%。
Abstract:This paper analyzed the content and proportion of conventional pollutants such as carbon, nitrogen, phosphorus and VSS/SS in the sediment from a municipal sewage pipeline in North China, and explored the dissolution conditions of sediment pollutants to overlying water in the municipal sewage pipeline and the utilization potential of carbon sources for sewage treatment. The content of carbon, nitrogen and phosphorus in the sediment from the sewage pipeline was high and characterized by high COD/TN and COD/TP (37.8 and 180.4). In addition, the BOD5/TN and BOD5/TP were 8.4 and 40.3, respectively. Proper stirring-sedimentation process achieved efficient extraction of biodegradable carbon sources from the sediment. The BOD5/TN and BOD5/TP in overlying water increased to 11.2 and 48.4, respectively, and the proportion of organic components increased from 35% to 52%.
