Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for removing algae-inducing substances,

The present invention relates to a system for preventing green algae generation, and more particularly, to a system for removing greenhouse gases by using a device for removing green algae causing material, To a system for removing algae-causing substances and a method for supplying dissolved oxygen, which can prevent the occurrence of algae in advance.

When organic matter (COD) accumulates on the bottom of a lake or a dam, microorganisms consume oxygen and are consumed at the same time. Therefore, it becomes a condition that oxygen easily becomes deficient. Especially in summer, (DO) at the bottom of the lake is almost 0 mg / L at the bottom of the lake due to stratification, and oxygen vacancy at the bottom of the lake promotes the dissolution of phosphorus from the bottom of the lake, leading to massive occurrence of algae There are many,

When the bottom of the lake is in the aerobic condition, phosphorus adsorbs to the bottom of the lake and is adsorbed to the bottom of the lake. However, when the bottom of the lake becomes anaerobic by vacancy, the bottom of the lake is reduced, It is not fixed and elution occurs.

In the eutrophicated lakes and marshes and dams, the elution and fixation of phosphorus is repeated at the bottom of the lake, and a continuous vicious cycle occurs due to eutrophication. To improve this vicious cycle, it is necessary to aerate the bottom of the lake.

Therefore, the most widely used technology to improve the oxygen vacancy of the hoger in the lake, swamp and dam is the abandonment circulation method and the deep abandonment.

The aeration system and the deep aeration system send compressed air to the lower part of the lake and the dam to raise the water in the deep part and to dissolve the oxygen in the lower part and at the same time some water is mixed with the water in the upper part, It is a way to circulate the bottom of the lake while circulating to the bottom of the lake.

However, this technique has a problem that the polluted degree of the lake is increased by mixing the anaerobicized water of the lower layer or the eluted water of the phosphate ion to the whole lake, and at the same time, the water at the upper part of the oxygenated lake is not stable There is a problem.

Therefore, a method of supplying oxygen without damaging the stratum corneum of a lake by improving the problems of the circulation method and the deep layer abandonment has been proposed. This is a method of directly supplying oxygen water to the bottom of the stratified stratum by the temperature weakening layer, A system for supplying pure oxygen to the oxygen dissolving apparatus using a pressurized tank or an underwater pump at the bottom of the lake is used to supply high concentration oxygen water to the bottom of the lake.

However, this technique has also been disadvantageous in that a considerable amount of energy is required because the production and supply of oxygen requires the use of PSA (pressure swing adsorption) or oxygen cylinder.

Another conventional example is to supply oxygen to the bottom of the dam by using micro-bubbles. This is due to the fact that microbubbles are generated at the bottom of the lake to increase the dissolved oxygen concentration, and even if the microbubbles are used, the bubbles themselves float and the microbubbles themselves may adversely affect the aquatic ecosystem.

As shown in FIGS. 1A and 1B, there is disclosed an apparatus that can raise water into the water at the bottom of a lake with a smaller energy than that of the prior art to flow oxygen into the lake after supplying oxygen.

That is, in a dissolved oxygen supply and algae growth control apparatus for a lake and dam constructed by supplying oxygen into a lake,

An upper end portion of an inflow portion for introducing water at a bottom portion of the lake is connected to a side surface of an outflow portion that flows out into the lake and an upper end portion of the outflow portion protrudes above the water surface of the lake and a lower end portion of the outflow portion is located below the water surface of the lake, A tubular body (1);

A blower (2) for power transmission of outside air;

An air transfer hose (3) connected to an outlet side of the blower and inserted into a side of an inlet of the lake guiding body; And

And an air inlet hose 3 connected to an end of the air induction tube 3 for injecting air flowing through the inlet of the lake induction tube 3 into the inlet of the lake induction tube 1, (4) for dissolving air in the water and for allowing water in the inflow section of the lake induction tube to flow to the outflow section of the lake induction tube,

A tank (6) floating on the water surface of the lake by a knitting machine (5) is provided with an inflow space and an outflow space. An inflow hose (7) is connected to an inflow port located below the inflow space of the tank, A lower end of the hose is positioned at the bottom of the lake and an outlet hose is connected to an outlet located below the outlet space of the tank so that the lower end of the inlet hose is located in a lake different from the lower end of the inlet hose,

Placing one or more lacquer guide tubes (1) on the divergence to position the inlet of the lacquer guide tube in the inlet space of the tank and locating the outlet of the lacquer guide tube in the outlet space of the tank Dissolved oxygen supply and algal growth control devices for lakes and dams are introduced.

However, such a conventional dissolved oxygen supply and algae growth control apparatus for a lake and a dam uses a method of spraying air flowing through a blower to dissolve air in water, which may result in a problem of low efficiency.

In general, algae growth occurs by eutrophication of a lake or a slow flow of suspended algae (phytoplankton), which accumulates on the surface of water and changes the color of the water significantly to green.

Therefore, when the lower part of the river is empty, the nutrients required for the growth of the algae from the river sediments are eluted from the sediments of the river. As a result, , It is necessary to remove these nutrients because it is highly likely to leach nutrients such as phosphorus from the sediment.

It can be seen that the technology that can remove the green algae on the premise of the stratum nondestructive and increase the oxygen transfer efficiency in the lower part of the stream is very important for the slow flow of the algae, It was not introduced.
