Description

An inhabitant of shellfish and a system for the quality of water purification}

The present invention relates to a shellfish breeding apparatus and a water purification system using the same, and more particularly to a shellfish breeding apparatus to help shellfish shellfish and a water purification system to purify the water quality using the same.

As urbanization and industrialization progress, the amount of pollutants such as dust, carbon dioxide, and sulfur dioxide in the air has increased, and these substances are not only introduced into rivers and lakes by rainfall along with surface pollutants, but also sewage and factory wastewater. The concentration of pollutants in the water has increased due to the continuous influx of pollutants in the back.

In particular, nutrients, including nitrogen compounds and phosphates, are inorganic elements necessary for the growth and growth of microorganisms causing organic decomposition, and are elements that must be continuously supplied for biological cell formation and life energy acquisition.

However, excessive nutrients such as nitrogen and phosphorus cause eutrophication, which exceeds the limit of the self-cleaning ability of the aquatic ecosystem, causing overgrowth of phytoplankton in the water, leading to a decrease in turbidity such as appeal. In severe cases, odor caused by decay occurs, and the problem of killing fish in the water occurs. Therefore, various methods for water quality improvement such as rivers and appeals are being implemented. However, the effectiveness of pollutants from untreated pollutants and nonpoint pollutant spills during rainfall is falling.

In order to solve the problem of deterioration of water quality such as eutrophication of rivers and lakes, there is a limit to the application of physicochemical water treatment methods, and the necessity of environmentally friendly construction methods is increasing. As environmentally friendly water treatment methods, there is increasing interest in using shellfish such as shellfish and horse clams for water quality improvement, and interest in using shellfish filtration to improve water quality related to algae control is increasing.

The zebra clam has a high filtration rate of about 1 L / day per individual and can improve the transparency of water bodies by filtering suspended organisms of various sizes, ranging from small bacteria to zooplankton. In addition, the binding and the high mobility and mobility is excellent because of the efficient water treatment. Since the filtration rate depends on the filtration capacity of shellfish species rather than shell size, shellfish should be selected according to the characteristics of the water body to be applied.

At present, the basic research to apply shellfish to water quality improvement is in the early stage, and the development of technology related to habitat is rarely done. Therefore, there is an urgent need to provide efficient habitats for shellfish in appeals that require water quality improvement and ecosystem recovery.
