Description

[0001] The present invention relates to an oxygen dissolving apparatus for preventing sea pollution,

TECHNICAL FIELD The present invention relates to an inorganic oxygen dissolving apparatus for marine pollution control, and more particularly, to an inorganic oxygen dissolving apparatus for marine pollution control for dissolving oxygen in collected seawater and purifying seawater by mixing yellow earth jugular water.

A dissolving apparatus that dissolves a gas is typically used to treat the wastewater to increase the dissolved oxygen (DO) content in the water. It is necessary not only to preserve the life of fish or other aquatic organisms, but also to keep the amount of dissolved oxygen above a predetermined value for the purpose of suppressing odor and inhibiting the production of organic substances. Biochemical oxygen demand (BOD) is determined by the amount of oxygen required for biological processes that destroy organic matter in the water. The higher the biochemical oxygen demand, the greater the amount of organic matter in the water and the greater the amount of dissolved oxygen needed do. The gas dissolving apparatus is very useful for increasing the amount of dissolved oxygen, and is particularly useful when the biochemical oxygen demand is high.

The gas dissolving apparatus is mainly used for the purpose of increasing the gas dissolution rate of oxygen or ozone in a liquid such as seawater or wastewater.

Such gas dissolving apparatuses are divided into two types, air diffusion type and mechanical type. The air diffusion type gas dissolving apparatus has a structure in which air or pure oxygen is introduced into water through a submersible porous diffusion member or a nozzle, and the mechanical gas dissolving apparatus has a structure for disturbing seawater to dissolve air in the atmosphere. The mechanical gas dissolver is further subdivided into a surface gas dissolver and a turbine gas dissolver. The surface gas dissolving device is designed to disturb water with a submergible or partially submerged impeller to introduce air into the water vapor and to rapidly change the contact area between air and water. The turbine gas dissolver uses a rotary impeller installed at a certain depth below the water surface of the treated water, and a vent pipe is supported coaxially with the impeller to supply external air to the water around the impeller.
