The use of wastewater and domestic sewage generated by industrial pollution enterprises around wading water areas such as upstream reservoirs or lakes and farmland pesticides and fertilizers around water areas causes the storage and precipitation of harmful waste residues into sludge, which seriously affects the water quality and the storage capacity of the water areas. To solve this problem, dredging is usually performed in a wading area such as a reservoir or a lake. In the construction process of dredging water areas, sediment in the water areas can be lifted up to cause certain pollution to the water areas, and the pollution is mainly expressed in two aspects: on one hand, natural garbage (such as humic branches, leaves, grass roots and the like), household garbage (such as plastic bottles, plastic bags and the like) and aquatic organisms (such as water hyacinth, duckweed and the like) deposited at the bottom of a water area are lifted and floated on the water surface in the dredging process, so that the upper water area is polluted; on the other hand, sediment, oil sludge and the like deposited at the bottom of the water can be resuspended in the dredging water area so that the turbidity of the water area becomes high and the middle and lower water areas are polluted. If the pollutants diffuse to the surrounding water area along with the water flow, secondary environmental pollution can be caused, and living of organisms such as fishes in the surrounding water area can be influenced, so that huge environmental pollution is caused, and the later ecological restoration cost is increased.
The existing water area dredging process for preventing the pollution source from diffusing mainly adopts the modes of a cofferdam enclosure, a pollutant blocking screen, an iron wire net and the like, but is influenced by factors such as construction regional environment, construction difficulty, construction regional range, pollutant blocking effect and the like, and the modes have certain use limitations and can not solve the problem of pollution of the upper layer and the lower layer of the water area in the dredging process.
