Description

A clay-layer removal method of man-made lakes for simultaneous removal of mud, splashes and deposits from artificial lakes

The present invention relates to an apparatus and a method for the easy and safe simultaneous removal of a layer of mud and deposits that have settled on the underwater bottom of an artificial lake.

When constructing artificial lakes, water pollution is caused by naturally occurring contaminated sediments. Such methods of purification of contaminated sediments include natural purification, surface coating, and collection of contaminated sediments. It is implemented.

The natural purification method is a method to purify the polluted deposits naturally if the polluted deposits are low in pollution, the influence of the ecosystem is small, and the self-purification capacity is sufficient, but it can be applied when there is no fear of secondary pollution. This is necessary and requires long-term monitoring according to the purification trend.

The surface coating method is to cope with the case of temporarily reducing the pollution of sediment by covering the sediment layer with high quality soil such as closed shell or sand silt with small particle size on top of the contaminated sediment layer. If the gas is generated in the future, the coating material may be further contaminated, which may cause a problem of ineffectiveness and cause secondary pollution, require high quality soils, and have a possibility of adverse effects such as diffusion of suspended solids.

The most commonly applied method is to perform the contaminated sediment collection operation to obtain the effect of suppressing the increase of turbidity by re-injury of fine particles, suppressing the gas generation by incomplete oxidation, and preventing the leaching of contaminants. However, the dredging work should be large and entail the emergence of secondary pollution problems and disposal of contaminated sediments caused by the business process.In determining the treatment method of contaminated sediments, the size of the construction, the physical characteristics of the dredging and the material to be dredged It should be selected by considering the amount of pollutant, available dredging equipment, conditions of dredging site, potential environmental impact, etc.In the process of polluted sediment, the analysis of dredged soil components, transportation and dumping method, pollutant treatment method, environmental The impact of secondary pollution from the treatment of polluted sediments is minimized by clarifying the effect.
