- 摘要：基于自然的修复理念，本研究开发了"旁路离线河流净化器技术与系统"，并以温榆河支流龙道河为研究对象，设计并建设了罗马东湖"塘-湿地系统"和龙道河拟自然河道工程.结果表明，该技术与系统可明显改善水质和生物生境，COD、氨氮和总氮平均浓度由（71.86±14.94）、（10.70±1.20）、（16.14±1.37）mg·L-1降低到（47.59±6.13）、（1.17±0.27）、（3.65±1.73）mg·L-1，平均削减率分别为31.8%、89.5%和77.4%，氨氮由劣Ⅴ类提升至Ⅳ类标准.龙道河生境质量评分由"一般"等级（94分）提升至"好"等级（151分）.该技术与系统具有不改变干流河道原有状态、不影响干流防洪、水质净化和生态恢复效果好等优点，适于支流丰富、排水灌渠密集或坑塘发达的污染河流生态治理与生态修复.
- Abstract：According to the natural-based solutions principle, the concept of bypass and off-line river purification system was developed for polluted river water quality improvement in urban, and such concept was applied in the Longdao Stream, a branch of Wenyu River. The project consisted of a naturalized Stream in Longdao and a constructed wetland in East Lake of Luoma. The practical application results showed that the bypass and off-line river purifier system greatly improved the water quality and biological habitat. The average concentrations of chemical oxygen demand (COD), ammonia nitrogen and total nitrogen (TN) were decreased from (71.86±14.94), (10.70±1.20), (16.14±1.37) mg·L-1 to (47.59±6.13), (1.17±0.27), (3.65±1.73) mg·L-1, and their removal rates were 31.8%, 89.5% and 77.4%, respectively. Water quality based on ammonia nitrogen concentration was upgraded from inferior Ⅴ to Ⅳ. The habitat quality score in Longdao Stream increased from the "general" rank of 94 to the "good" rank of 151. The technology and system has many advantages, such as non-changing the original state of the main stream channel, non-affecting the flood prevention of the main stream, good performance of water quality purification and ecological restoration. Therefore this technology and system is suitable for the ecological treatment and restoration of polluted rivers with abundant tributaries or dense drainage and irrigation channels or well-developed pits and ponds.
