1. An equipment for in-situ restoration of sediment, comprising an amphibious platform and following devices provided thereon:
a screw suction device, one end of which is hinged to one end of the amphibious platform, and the other end of which can extend into the sediment for sucking sediment;
a dehydration device that is provided downstream of the screw suction device and communicated with the one end of the screw suction device for dehydrating the sediment;
a sediment treatment device that is provided downstream of the dehydration device for treating the sediment and processing it into a planting base;
a grass blanket processing device that is provided downstream of the sediment treatment device for planting submerged plants on the planting base to form a submerged grass blanket;
a grass blanket paving device, one end of which is close to the grass blanket processing device, and the other end of which extends toward the screw suction device and extends into the water, for paving the submerged grass blanket to the bottom of the water;
a drainage pipe that respectively communicates with the dehydration device and the sediment treatment device; and
a hopper through which the sediment is conveyed between the dehydration device and the sediment treatment device.
