A COMPREHENSIVE ECOLOGICAL RESTORATION SYSTEM FOR URBAN RIVER EUTROPHICATION MANAGEMENT
-
摘要: 以河道富营养化治理为研究对象，通过引清入河、水下种植沉水植物、混养鲢鳙等水生动物，并应用原位修复装置等形成1个相互配合的综合生态修复系统，对河道富营养化进行治理。于2017年8月-2018年7月，对5个采样点河道水体富营养化指标进行测量，结果表明：河道水体中总氮（TN）浓度、总磷（TP）浓度、高锰酸钾盐（CODM n）、氨氮（NH3-N）浓度显著下降，水体透明度明显提升。这说明采用综合生态修复系统治理城市河道治理风险低、治理效果佳，可以推广使用。Abstract: Taking the river eutrophication control as the research object, the eutrophic treatment of the river course was carried out by introducing clear natural water into the river, underwater planting submerged macrophytes, polyculture of silver carp and bighead carp, and applying advanced in-situ restoration devices, in order to form an integrated ecological restoration system. The algal bloom index was measured at 5 sampling sites in Foshan from August 2017 to July 2018. The results showed that the concentration of total nitrogen (TN), total phosphorus (TP), potassium permanganate salt index (CODMn) and ammonia nitrogen (NH3-N) in the river water decreased significantly, and the transparency of the water increased significantly. It showed that the integrated ecological restoration system could be widely used for the treatment of urban river with lower risk and better treatment effect.
