Description

{SHIP FOR REMOVING WATER-BLOOM}

More particularly, the present invention relates to an algae removing line, and more particularly, it relates to a green algae removing line capable of uniformly flowing a green algae floating on a lake water surface even if the weight of a ship changes, And the like.

Water pollution of rivers and lakes is becoming more and more intense due to industrial development, population increase and concentration, increase of pollutant emissions due to improvement of living standard, increase of fertilizer usage for inventory of agricultural productivity, And the aesthetics of the lake and the hydrophilic environment are hindered.

In addition, when the generated green algae causes a problem of clogging of the filter paper in the water treatment process, and toxic substances such as Mocrocystin are also worried when the occurrence of the algae is severe, the water quality of the eutrophic lake Improvement is urgent.

As described above, the cause of the green algae is a phenomenon that occurs due to excessive amounts of nitrogen, phosphorus, and other organic substances in the water. Therefore, it can be solved by removing such eutrophication substances.

The biological treatment method using microorganisms is widely used for the removal of nitrogen and organic matter, and the removal method of phosphorus can be removed as a chemical treatment, but it is necessary to install a large facility such as an aeration tank, reaction, flocculation, and sedimentation tank .

As an example of a conventional apparatus for removing green tide and red tide, the above-described method is disclosed in Korean Patent Registration No. 10-0356397. In this method, water is separated from water introduced through an algae inflow path installed in front of a ship by an air nozzle The algae stored in the primary storage tank is again lifted to the secondary storage tank by the secondary conveyor and dehydrated while passing through the vacuum dehydrator, So that it can be incinerated on the ship.

However, in the conventional green tide removing apparatus, as the green tide and water flow into the inside of the hull, the algae inflow path is submerged below the water surface, so that the green tide is not smoothly introduced during continuous operation. There is a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a greenhouse which floats on the surface of a lake, even if the lake water level changes due to rainfall and drought, A green algae eliminating line that can be uniformly introduced through a green algae inlet window formed at the front of the ship, thereby improving the algae removing efficiency of the algae.

The greenhouse storage compartment 300 and the greenhouse storage compartment 300 are connected to each other by a filtration unit 400, And a green tide transmitting unit 500 for transmitting the green tide.

The hull 100 is floated on the lake and is movably installed, and a greenhouse inflow window 110 for inflow of a greenhouse of the lake water surface is formed forward.

In this case, the hull 100 is a body of a dedicated vessel for removing a green tide while actively coping with a green tide occurring in a lake, and has a streamlined structure like a conventional ship. Inside the hull 100, (Not shown) for floating at a predetermined height, and a propeller 130 for moving at the lake at the rear.

In addition, the hull 100 can be configured so that the operator can remotely adjust the movement of the hull through control equipment on land so that the removal of the algae can be removed hygienically and safely.

For reference, the proverbial meaning of the appeal is collectively referred to as an inland watershed, which is classified as a lake, a marsh, a wetland, or a wetland. A lake is a lake with a depth of 5m or more. A swamp has a depth of 5m and is called a place where floodplains are abundant. A floodplain is a floodplain of water plants and a depth of less than 1m. Wetlands are places where wetland plants are covered.

The lake is classified as above, but here it is defined as a term including a river, an agricultural reservoir, a lake for a lake for fishing, a pond in a golf course
