Abstract

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 (COD_Mn) 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.
