摘要:以華北地區(qū)某城市污水管道沉積底泥為研究對(duì)象，在分析底泥中碳、氮、磷和VSS/SS等常規(guī)污染物含量及其組分占比的基礎(chǔ)上，探索城市污水管道沉積底泥污染物向上覆水溶出的條件及其碳源應(yīng)用于污水處理的潛力。結(jié)果表明：污水管道沉積底泥污染物中碳、氮、磷含量較高，且具有高COD/TN、高COD/TP特征，比值分別達(dá)到37.8和180.4，且BOD5/TN和BOD5/TP分別達(dá)到8.4和40.3；適宜的攪拌-沉淀作用能夠?qū)崿F(xiàn)沉積底泥中可生物利用碳源的高效提取，同時(shí)上覆水中的BOD5/TN和BOD5/TP可分別提升至11.2和48.4，有機(jī)組分占比從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%.
