BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing a configuration of a green algae control device for removing algae and algae according to the present invention; Fig. Elements are denoted by the same reference numerals, and redundant description thereof will be omitted.

It is also to be understood that the terms first, second, etc. used hereinafter are merely reference numerals for distinguishing between identical or corresponding components, and the same or corresponding components are defined by terms such as first, second, no.

In addition, the term " coupled " is used not only in the case of direct physical contact between the respective constituent elements in the contact relation between the constituent elements, but also means that other constituent elements are interposed between the constituent elements, Use them as a concept to cover each contact.

The green alga controlling apparatus according to an embodiment of the present invention basically comprises a housing 100 having an internal space 110 in which fibers 200 absorbing total phosphorus are received, a plurality of housings 100, A first connection member 310 connected to one end of the first connection member 310 and connected to one end of the float 400 floating on the water surface of the stream 1, And a fixing member 500 for fixing the first connecting member 310 to the bottom surface of the river 1 (Figs. 1 and 2).

Here, a through hole 120 penetrating to the inner space 110 may be formed on the outer surface of the housing 100 (FIG. 1).

The housing 100 may be formed of plastic or fiber, or may be formed of a fibrous net.

That is, when the river water containing the total phosphorus flows through the through hole 120 into the housing 100, the total phosphorus is absorbed by the fiber 200. As the total phosphorus is continuously absorbed into the fiber 200, the total phosphorus contained in the water 200 is concentrated in the fiber 200 inside the housing 100, so that the concentration of the total phosphorus in the river water can be lowered.

The mechanism by which the total phosphorus is concentrated on the palm fiber is described as follows.

Concentration of matter in aquatic ecosystems is carried out naturally by the action of microorganisms. Generally, in a water environment, a stone or a leaf is a substrate, and the coconut fiber according to the present invention may also be a substrate.

The surface of the substrate attracts nutrients and bacteria such as total phosphorus and total nitrogen by electrical or hydrophobic exchange action. Airborne bacteria attach to the surface of the substrate, grow and divide, forming a biofilm, which converts nutrients from low to high concentrations. Bacteria adhering to the matrix have a larger cell size and higher enzyme activity than airborne bacteria, thus contributing to the material circulation.

Attachment bacteria have different rates of attachment, desorption, and growth depending on the type of substrate. The rougher the surface of the substrate, the wider the surface area, the larger the attachment space of the bacteria, and consequently the concentration rate.

Coconut fiber is a structure that has a wide surface area and easy flow of artifacts, and is a material that can have a high efficiency in concentration of total phosphorus belonging to nutrient salts.

The apparatus for controlling green algae according to an embodiment of the present invention may be constructed such that a water garland 130 is cultured in an inner space 110 of a housing 100 (FIG. 1).

As the total phosphorus is concentrated on the fibers 200 of the inner space 110 of the housing 100, the algae consuming the phosphorus is also concentrated in the inner space 110 of the housing 100. Since the water fleas 130 are living organisms that ingest algae, when the water fleas 130 are cultured in the internal space 110, the water fleas 130 can remove the algae contained in the rivers as they consume the concentrated algae do.

The daphnia 130 may be cultured in the inner space 110 before the housing 100 is installed in the river. Even if the housing 100 is installed on the river without culturing the daphnia 130 in the inner space 110, the inner space 110 of the housing 100 can have a high concentration of algae fed by the water spikes 130 So that the water fleas 130 existing in the river can be naturally introduced into the internal space 110 of the housing 100.

For this purpose, the diameter of the through-hole 120 is preferably between 1 mm and 4 mm so that the small-size daphnia can pass through the through-hole 120.

In addition, water lilies (130) can be replaced by any living organisms that feed on algae.

The green alga controlling apparatus according to an embodiment of the present invention has the following advantages.

First, since the composition used in the algae control system is environmentally friendly, it is possible to remove algae and algae contained in the stream without adversely affecting the ecosystem of the stream.

Second, since the composition used for the algae controlling device does not include expensive members, it corresponds to an economical and practically applicable algae controlling device.

Third, by allowing the daphnia to exist in the inner space 110 of the housing 100, it is possible to protect the daphnia from natural enemies of the daphnia, thereby increasing the number of daphnids and effectively removing the algae.

Fourth, the green alga controlling apparatus according to an embodiment of the present invention is not required to constitute a separate reaction tank.

The fiber 200 of the green alga controlling device according to an embodiment of the present invention may be a coconut fiber.

Since coconut fiber is an effective substance in the absorption of total phosphorus, it is possible to enrich the total phosphorus environmentally when using coconut fiber.

The green alga controlling apparatus according to an embodiment of the present invention is installed in a river by connecting a plurality of the housings 100 to the first connecting member 310.

Specifically, a plurality of the housings 100 are connected to the first connecting member 310, a float 400 floating on the water surface of the river 1 is coupled to one end of the first connecting member 310, The fixing member 500 is coupled to the other end of the connecting member 310.
