About the Dredging Project
In the past, there were many dredging projects in waterways, ports and large-scale inland rivers, which formed the corresponding technical methods and mechanical equipment.
Around the removal of pollutants in the sediment during the treatment of rivers and lakes, many "environmental dredging" projects have been explored, that is, the pollutants gathered in the sediment of rivers and lakes are removed from the lakes and rivers by dredging.
The difference between environmental protection dredging and engineering dredging is that the sediment thickness of dredging is very thin, and the sediment of most environmental protection dredging projects is 20cm to 40cm.
Therefore, the positioning of the dredging equipment itself and the precision of the operating system are very high. Eutrophic rivers carry out large-scale environmental silt removal projects around the removal of nitrogen and phosphorus in the sediment.
In order to improve the water quality of the river, urban and rural rivers are generally dredged. Compared with lakes, urban and rural river environmental dredging projects can be slightly more extensive, because the river itself fluidity and exchange characteristics, construction accuracy and secondary pollution prevention requirements are less sensitive than lakes.
At present, the environmental protection silting project generally adopts the stacking mode in the sludge treatment.
The mud generated by silting is first stored in the storage yard, and then the land is reduced or treated and utilized after precipitation.
