中文摘要:
      常州市藻港西支河为一条非封闭性黑臭河道,采用深层微孔层流曝气、微生物强化降解和生态浮岛为主的生物—生态复合修复技术进行治理,对连续 5个月的理化指标进行监测。结果表明,与治理前相比,治理后总磷、总氮、氨氮的浓度均显著下降,水质由劣Ⅴ类提升至Ⅲ~Ⅳ类;COD浓度降幅达70%;河道底泥厚度削减50%,底泥中的总氮、氨氮的含量总体呈下降趋势,其中部分检测点浓度降幅为50%。在改善水质的同时,以水生植物为主体的生态浮岛亦兼顾到城市河道的景观需求。
英文摘要:
      The west branch Zaogang River in Changzhou City is a non closed black and smelly river. It is treated by integrated bio remediation technology based on deep microporous laminar aeration, microbial enhanced degradation, and ecological floating island. The continuous monitoring of 5 months period shows that the concentration of total phosphorus, total nitrogen and ammonia has decreased significantly, and the water quality is improved from below class Ⅴ to class Ⅲ to Ⅳ; COD is decreased by 70%, the thickness of sediment is reduced by half, and the total nitrogen and ammonia content in the sediment shows a downward trend in general, and the decrease at some areas reached 50%. While improving water quality, the ecological floating island with aquatic plants also meets the need of landscaping in urban rivers.
