The invention provides a protectiveness ecological dredging method for rivers and lakes and wetland. The method includes the following steps that an excavation area of the rivers and lakes and the wetland is subjected to area dividing, and is divided into a plurality of grid units; meanwhile, the excavation area is accurately positioned, and is subjected to layering, the upper layer is an ecological layer, and the lower layer is a sludge layer; the ecological layer and the sludge layer of the first grid unit are moved, and a first blank grid unit is formed; the second grid unit adjacent to a groove is selected, a twisting and sucking device with a plow is adopted, the ecological layer is transferred into the groove through the plow in the twisting and sucking device, meanwhile, the sludgelayer is removed, and a second blank grid unit is formed; and the third grid unit adjacent to the second blank grid unit is subjected to ecological dredging treatment in the same manner till the sludge layer of the excavation area is completely removed, the ecological layer is subjected to complete transplanting, and a whole ecological area is formed.
Description
technical field [0001] The invention belongs to the field of ecological environment management, in particular to a plow-type protective ecological dredging method for rivers, lakes and wetlands. Background technique [0002] With the rapid economic development, the ecological environment has been destroyed, especially the pollution of water resources. Water is a resource that human beings depend on for survival. However, most of the rivers, lakes and wetlands in our country have been polluted. The silt of polluted rivers, lakes and wetlands contains a large amount of pollutants. Under certain conditions, these pollutants will be released into the water body, causing the water quality to deteriorate. Pollutants will be deposited in the silt layer at the bottom of the water body and become the internal source of water pollution, which not only affects the water quality, but also is very detrimental to the self-purification of the natural water body, resulting in the continuou...
