Three-dimensional combined ecological purification device

The utility model provides a three-dimensional combined ecological purification device applied to the technical field of ecological purification, the purification device is arranged on a river channel through a suspension bridge, a working platform is provided for workers, an aquatic plant bag with aquatic plants is placed in a turnover ecological frame, and the turnover ecological frame is arranged on the river channel. The aquatic plant bags arranged in the grid mode form a water surface and underwater combined three-dimensional plant purification area, so that the ecological purification capacity of river water is effectively improved, reconstruction of a river channel ecological system is facilitated, and when the aquatic plants are too flourishing or individual plants die, the ecological purification effect is improved. A worker can stand on the suspension bridge and pull the turnover pull rope to pull the turnover ecological frame to turn over, so that the sliding bag frame slides and gathers towards th
