Study of technologies foroperation management of subsurface constructed wetland treating polluted river water
Based on the example of Lupu River subsurface flow constructed wetland, this paper introduces the design parameters of subsurface flow constructed wetland, and analyzes the problems of COD, TN removal instability and matrix blockage during the operation of subsurface flow constructed wetland. The problem has been put forward corresponding improvement measures.
