Due to the deterioration of water by nutrients such as nitrogen and phosphorus contained in fertilizers, livestock wastewater, domestic sewage, and factory wastewater, green algae are generated in rivers and lakes, and red algae in the ocean are destroying ecosystems. Water nutrients eutrophicated by nutrients contained in the waste water cause the algae to thrive.

When the algae thrives on the surface of the water, it prevents the light from penetrating, thus preventing the photosynthesis of aquatic organisms and lowering the oxygen dissolution rate in the water, thus losing the self-cleaning ability of the water. Green algae and red algae generated by eutrophication can shut off the oxygen supply to water and kill fish and fish that live in the water.

In addition, when the red tide phenomenon occurs on the water source paper, a problem of odor caused by algae occurs, and the high-purity treatment must be performed, and trihalomethane (THM), a toxic substance, may be formed by excessive chlorine disinfection.

A plan schematic diagram of a mobile algae removal device according to an example.

Mobile algae removal device according to an embodiment of the present invention hull 110, flocculant input unit 120, microbubble generating unit 130, scraper unit 210, sludge hopper 230, a pair of floating It is composed of a mobile bird removal unit including a unit 250, a power generating unit 260 and the control unit 270.

The hull 110 is a body of the ship for removing the algae while actively dealing with algae in the appeal, it is preferably a streamlined structure in the movement of the hull, if the flow of water flows from left to right, the hull is The sludge S is collected in the sludge hopper 230 which will be described later while traveling from right to left.

In addition, the flocculant injection unit 120 and the micro-bubble generating unit 130 is disposed in front of the hull 110, the direction key 300, etc. may be disposed in the rear end.

The flocculant inlet 120 is provided at the front end of the hull and injects the flocculant into the appeal. The flocculant is a material having the ability to neutralize the charge of the colloid to agglomerate suspended solids or algae, and the crosslinking ability to bind the colloid particles to each other, the former should be an ion having an opposite charge to the aggregated colloid, the latter is a polymer material It should be possible. Therefore, it is preferable to use what has these two conditions as a flocculant.

In general, widely used flocculants include metal salts or synthetic polymers, natural polymers such as aluminum salts, iron salts, chitosan, polyacrylamide, etc., which are easily hydrolyzed to form hydroxide polymers having a positive charge. More specifically, poly aluminum chloride (PAC: Poly Aluminum Chloride), aluminum sulfate (Aluminum Sulfate: Al ₂ (SO ₄ ) ₃ 8H ₂ O), ferrous sulfate (FeSO ₄ H ₂ O), sulfate Ferric Sulfate (Fe ₂ (SO ₄ ) ₃ ), Ferric Chloride (FeCl ₃ ), Calcium Hydroxide (Ca (OH) ₂ ), Calcium Oxide (CaO), Aluminum Acid At least one organic-inorganic flocculant selected from sodium aluminate (Na ₂ Al ₂ O ₂ ), chitosan, and polyacrylamide may be used.
