Farmland ecological ditch system for collecting and treating multiple water sources in complex terrain

Abstract

The utility model belongs to the technical field of water collection and treatment, and discloses a farmland ecological ditch system for collecting and treating multiple water sources in complex terrains, a porous drainage ditch is arranged at the most upstream position, a snakelike ditch is arranged at the position of the terrains with large gradient or high flow speed, and a filter wall is arranged at the position where the ditch is wide and the water flow is stable. The suspended wetlands are arranged at the middle and lower streams, the channels are straight, and the water flow is moderate; the downstream channel is arranged at the most downstream position; the porous drainage ditch, the filtering wall and the downstream ditch area are communicated with a domestic sewage pipeline, and the porous drainage ditch is communicated with a riverway or underground water body through a water inlet pipe and a water suction pump; and the filtering wall, the suspended wetland and the downstream ditch area are communicated with a water taking irrigation pipeline. By combining all the technical schemes, the system has the advantages that different treatment modes are set according to different terrain characteristics, various water sources can be collected and treated in the whole process, and water can be directly transferred for peripheral irrigation through the water taking irrigation pipeline.
