Abstract

PURPOSE: An apparatus for removing algae is provided. CONSTITUTION: The apparatus comprises an algae skimmer (1) which is moves up and down according to the distribution position of upper part algae and inhales algae; a rapid mix (3) which receives the inhaled algae; a coagulating agent storage tank (2) which injects a coagulating agent into the rapid mix (3); a flocculation basin (4) which make the size of floc be larger; a drum filter (5) which filters the floc from the flocculation basin (4); a nozzle sprayer which washes and removes the floc sludge attached to the filter; and a concentration bath (6) where the generated sludge is transferred.

Description

Algae Remover

The present invention relates to a method of inhaling algae, agglomeration of algae and a method of filtering agglomerated algae to remove algae (red and green algae) from the water.

At present, in Korea, when the tide occurs in the coastal waters, measures such as sinking or moving cages in farms, spreading ocher, and urgent release are taken, but this is only a temporary measure and is not an effective alternative. In addition, deep aeration, copper sulfate spraying, and low soil dredging are mainly used as treatment methods in the appeal, but they are not only expensive but also a temporary effect can not be seen as a fundamental solution.

The present design is an algae eliminator with a algae removal system on top of the barge, making the algae (red and green algae) removal rates above 70%. In the ocean, it can handle 600m ³ / hr in consideration of the wide range of polluted areas. On the land, the processing flow is reduced to 100m ³ / hr for the convenience of transportation.

The present invention processes algae using an algae removal system equipped with an algae removal system when a large amount of algae (red and green algae) occurs in coastal and lakes. The algae induction plate 1 is used to inhale algae material from the upper water layer into the eliminator, which has a control function to move up and down. The water containing the inhaled algae is introduced into the rapid mixing tank (3), and as the first step of the flocculation process, the appropriate flocculant and the dosage are quantified from the flocculant storage tank (2) and administered to the rapid mixing tank (3). The administered flocculant is dispersed evenly throughout the treated water in the shortest possible time to allow efficient physicochemical reaction and contact between the flocculant and the contaminant (red tide) and then transferred to the floc forming paper 4. The very fine flocs produced in the quick mixing paper 3 collide with each other with slow stirring in the floc forming paper 4 to increase the size of the flocs so that they are easily filtered out in subsequent filtration devices. The grown flocs enter the rotary drum filter device 5 and are filtered. This device is a device for fine filtration and has a drum-type filter. The treated water flowing through the floc forming paper flows into the rotating drum, and red tide and suspended solids flocs are filtered through the filter, and the remaining purified water is discharged to the outside of the drum. Exit Such a process can be said to be a direct filtration process which greatly shortened the processing time of the general coagulation process from 15 minutes to 30 minutes to 3 to 5 minutes. Floc sludge attached to the filter is washed and removed using a nozzle cleaning device for cleaning the filter mounted on the outside of the drum. The sludge generated at this time is transferred to the concentrated water tank 6 to reduce the moisture of the sludge to reduce the volume of the sludge.

This algae removal system not only removes algae directly, but also mechanically removes algae containing nutrients into cells and disposes them out of the appeal to reduce the concentration of nutrients in water. In addition, the use of flocculants is expected to contribute to the preservation of the overall environment rather than a temporary effect due to the removal of suspended pollutants and phosphorus (P) other than algae.

Claims (1)

The algae are inhaled using an alga induction plate (1) that can be adjusted up and down according to the distribution position of algae material located in the upper layer. The aspirated water flows into the rapid mixing tank 3, and as a first step of the flocculation process, the appropriate flocculant and the dosage are quantified from the flocculant storage tank 2 and administered to the rapid mixing tank 3. Transfer to the floc forming paper (4) to increase the size of the floc flow into the rotary drum filter device (5) and filtered. The purified treatment water is discharged to the outside of the drum. The floc sludge attached to the filter is washed out using a filter cleaning nozzle injector attached to the outside of the drum. Sludge generated at this time is moved to the concentrated tank (6). Algae remover operated in this way.
