Description

A removal system of deposit in rivers used an inhaler

The present invention relates to a system for removing sediments, reservoirs, water quality of lakes and bottom sediments. More specifically, the size of the treatment tank is small, the structure is simple, easy to manufacture, and the production cost is low. In addition, it can be installed on a barge to move the surface of rivers and lakes, improve water quality, collect aggregate accumulated on the floor, and carry out dredging work of the floor. The present invention relates to a system for removing sediments, reservoirs, water quality of dams and streams that can improve the quality of water.

In general, deposits accumulate on the floors of lakes, reservoirs, dams and rivers, which contain organics, minerals and various heavy metals that adversely affect the water quality during turbidity. And aggregates, such as gravel, sediment sludge that pollutes the water is formed by mixing.

The sediment sludge in the sediment is an organic substance that consumes dissolved oxygen in the raw water, which contains various pollutants such as nitrogen and phosphorus heavy metals that cause eutrophication, which deteriorates the water quality, and abnormal gas propagates due to eutrophication, causing harmful gases to the living organisms. And the loss of self-cleaning ability of lakes, reservoirs, dams and rivers, not only to accelerate pollution, but also to accumulate on the floor with the aggregates and to reduce the depth of water, thereby gradually reducing the storage capacity of the lakes, reservoirs, dams and rivers. In order to remove the bottom sediment and maintain a constant low capacity, the conventional dredging work was carried out, but the conventional dredging work can remove the bottom sediment, but the sediment sludge mixed in the sediment. Can be diluted into raw water without removing it, Salts, as well as be used as construction aggregate not there is a significant amount of deposited sludge is mixed in the collected sediment to, as well as there was a problem that odor is severe contamination of the surrounding atmosphere and soil.

In order to overcome the problems described above, the applicant filed with Korean Patent Office on March 25, 1999 under the name of "Method and system for removing bottom sediments of lakes, reservoirs, dams and rivers". Referred to herein).
