Ecological ditch system for improving receiving water non-point source pollution treatment

The invention relates to an ecological ditch system for improving receiving water non-point source pollution treatment, and effectively solves the problem of how to effectively utilize the ecological ditch technical measures to treat receiving water non-point source pollution. The ecological ditch system for improving receiving water non-point source pollution treatment includes a sedimentation tank for precipitating silt and other solid matters carried by non-point source inflow water, and an ecological purification area for removing part of pollutants in non-point source inflow water, the sedimentation tank and the ecological purification area are arranged along the flow direction of the non-point source inflow water in order, a basket grating device for intercepting suspended matters in water is disposed above the sedimentation tank, non-point source inflow water enters the basket grating device and then enters the sedimentation tank, the sedimentation tank and the ecological purification area are connecte
