Description

Technical Field [0001] The present invention relates to a wireless water surface float for removing algae,

The present invention relates to a radioactive liquid immersion fluid for algae removal capable of removing algae while flooding the water surface such as a lake and a river, and a method of operating the same.

Recently, water pollution has been raised as one of the environmental problems, and accordingly, there is a growing interest in methods for measuring the toxicity of water quality.

Generally, in a river, the growth of algae due to the influx of nutrients is not a big problem directly, and the lack of dissolved oxygen is a problem.

On the other hand, unlike rivers, the lake has become a big problem due to the overcrowding of the algae due to the congestion of water bodies.

At the beginning of the lake, the concentration of nutrients is low and the production and consumption in the water system are balanced to maintain the nutrient status. However, as the concentration of nutrients gradually increases and the productivity of the lake increases with time, .

Eutrophication is a phenomenon that occurs when substances such as carbon (C), nitrogen (N), phosphorus (P) These nutrients are contained in the forests, as well as in the household wastewater and plant wastewater as well as in the detergents, agricultural fertilizers, livestock products and synthetic detergents.

In this way, watersheds with active human activities in the watershed are eutrophiled at a faster rate than natural conditions. As nutrients continue to enter the lake in various forms, water quality pollution occurs gradually when the lake is beyond the self - sufficiency of the lake. This process is further promoted by stratification of the reservoir. Even if organic pollutants are decomposed and removed, minerals that will become nutrients can accumulate in the propagation of aquatic microorganisms.

As mentioned above, the occurrence of algae is caused by the generation of algae. When the natural nutrients such as nitrogen (N), phosphorus (P) and temperature condition become appropriate environmental conditions, large amounts are reproduced at one time and depleted dissolved oxygen An adverse effect of disturbing the ecosystem occurs.

Conventional algae removal methods include a chemical spraying method for destroying algae, an ultrasonic treatment method using ultrasonic waves, an ozone treatment using ozone (O3), and a bio-control method.

Conventionally, chlorine or ozone treatment for algae removal causes carcinogenic disinfection by-products in the case of chlorine disinfection and ozone removal is effective for removal of hobby materials. However, when algae are generated in large quantities, removal is limited, There is a disadvantage that the effect is not persistent.

The method of spraying and removing the loess when the algae are generated is mainly by the coagulation sedimentation along with the algae. However, since this method is sedimented in the bottom of the lake, the phosphorus (P) There is a problem that the potential cause of the algae eluting in the future is intact and the algae is reproduced.

Particularly, algae has a problem that it is difficult to complete treatment by the conventional precipitation process because of the nature of self-floating, the repulsive action of surface charge and the hydrophilicity of the cell surface.

Recently, attempts have been made to remove algae using ultrasonic waves. However, ultrasound technology has a low efficiency due to its diffusion type, and has been adversely affected by the projected water in the longitudinal direction. For example, Korean Patent No. 1,570,120 discloses a technique for removing green algae by using ultrasonic waves, but the technique has also been developed in the direction that ultrasonic waves are projected into water.
