Embodiment Construction
[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0020] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0021] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations or positional relationshi...

The invention provides a protective ecological dredging method of river lake and wetland integral transplantation. The method comprises the following steps that mesh division is performed on an excavation region of a river lake and a wetland, the excavation region is divided into n grid units; meanwhile, the excavation region is precisely positioned and layered, the upper layer is an ecological layer, and the lower layer is a sludge layer; the ecological layer and the sludge layer of the grid unit at the first position are removed to form a first blank grid unit; the sludge layer of the grid unit at the second position is removed and moved to the first blank grid unit, the sludge layer of the grid unit at the second position is removed, and a second blank grid unit is formed; and the ecological layer of the grid unit at the third position is removed and moved to the second blank grid unit, the sludge layer of the third position grid unit is removed, and a third blank grid unit is formed. According to the method, the ecological layer of the grid unit at the Nth position is removed and moved to the N-1th blank grid unit, the sludge layer of the N position grid unit is removed, and integrated protective ecological sludge removing for the river lake and the wetland is realized.
Description
technical field [0001] The invention belongs to the field of ecological environment management, and in particular relates to a protective ecological dredging method for overall transplantation of 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 bod...
