Abstract
An equipment for in-situ restoration of sediment, including an amphibious platform and following devices provided on the amphibious platform: a screw suction device, one end of which is hinged to one end of the amphibious platform, and the other end can extend into the sediment for sucking up the sediment; a dehydration device that is provided downstream of the screw suction device and communicates with one end of the screw suction device; 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 extends toward the screw suction device and into 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. In the invention, the highly polluted sediment is subjected to bio-safety disposal to form a planting base for the growth of submerged vegetation, so as to realize the in-situ restoration of the sediment of rivers and lakes.
