Reverse forward weir desilting system

The invention relates to the technical field of silt treatment, in particular to a reverse forward weir desilting system, which comprises a desilting device, a clean water tank and a sand storage tank, the desilting device comprises a desilting tank, a clean water channel, a clean water platform, a forward weir and a desilting gate, and the desilting tank comprises a desilting tank bottom plate, aleft side wall and a right side wall. The left side wall is fixedly mounted on the left side of the desilting tank bottom plate, and the right side wall is fixedly mounted on the right side of the desilting tank bottom plate. The structure is reasonable and compact, the conception is ingenious, sedimentation of bed load and suspended load in natural incoming water is completed by arranging the desilting device, and the upper layer of the natural incoming water is made to be clean water; by arranging the clean water platform and the forward weir, after the water level of clean water below theclean water platform is hi
