Description

Technical Field [0001] The present invention relates to a sea water treatment system using micro bubbles,

The present invention relates to a system and a method for treating environmentally friendly seawater using microbubbles, and more particularly, to a system and a method for treating environmentally friendly seawater using microbubbles, To a multifunctional system for simultaneously supplying necessary dissolved oxygen and a seawater skimmer for removing harmful organic substances in a water tank, and a method for treating seawater using the same.

In general, seawater live produces many secretions in the course of transport and storage, the main component of which is protein. The excrement, secretion, food remnants, etc. of the fish and shellfish are adsorbed with the bubbles to form bubbles. The above-mentioned bubbles staying in the upper part of the aquarium and various foreign substances (such as feces, secretions, food remnants, etc.) on the bottom of the water pipe are decayed after a certain period of time to pollute the water quality and increase the bacterial growth.

Generally, excreta excreted by fish and shellfish are corrupted by fungi and bacteria in water, and ammonia (NH ₃ / NH ₄ ) is generated by heterotrophic bacteria (= ammonia bacteria) upon decay, and the ammonia bacteria secretion Nitrosomonas bacteria (= nitrite bacteria) are formed and decompose in themselves to produce nitrite (NO ₂ ). Nitrite bacteria (nitrate bacteria) are formed by the secretion of the nitrite bacteria, which also decompose in the bacteria itself to generate nitrate (NO ₃ ). The ammonia can be divided into ammonium (NH ₄ ) and ammonia (NH ₃ ). When ammonium is more than ammonia, the pH becomes neutral or acidic and the effect on fish and shellfish is small. However, when ammonia is more than ammonium, It becomes alkaline and its effect on fish and shellfish becomes serious due to serious toxicity.

It is known that the mean pH of seawater is 7.8 and under these conditions it is known that heterotrophic bacteria increase exponentially every 15 minutes. And the proliferation rate of nitrosomonas bacteria doubles about 24-36 hours, and it takes about 7-15 days on average to form nitrate bacteria necessary for aquariums, and it decomposes ammonia nitrite nitrate.

As the ammonia disappears and the nitrite level rises to the highest level and the level becomes noticeably low, nitrate formation occurs when no ammonia nitrite is detected in the water tank. After the toxic ammonia or nitrite is completely removed, Is stable. That is, in order to maximally extend the water quality of the aquarium to a satisfactory state, it is necessary to solve the problem of the generation of bacteria by the excrement of fish and shellfish as described above.

Conventional water purification systems for aquariums for filtering and purifying the bubbles and various foreign substances of the organic contaminants have been mainly classified into an upper filtration system, a low-concentration system, a side filtration system, an upper filtration system, and a bubble skimmer system.

In the case of the upper filtration system, a filtration tube is provided so as to be exposed to the upper end of the water tank, and foreign substances suspended in the upper part of the water tank are sucked by a pump installed at the lower part, filtered through a filter tube, and water is supplied to the water tank again through a cooler. A part of the froth suspended in the upper part of the water tank is removed, but the foreign matter remaining in the water tank as a whole is not filtered.

In this method, a filter is installed on the bottom surface of the water tank, and the water is sucked by the lower pump to supply the water to the water tank through the cooler. This means that the water in the water tank is circulated in general, There was a difficulty in removing bubbles and foreign matter.

In the side filtration system, a filtration tube is installed on one side of the water tank, and the water is sucked by a pump installed at the lower side, and the water is circulated back to the water tank through the cooler. However, the foreign matter filtration is performed at the upper part of the water tank, Filtration is impossible. In the upper filtration method, a filtration tube is installed at the upper part of the water tank, the water is sucked through the pump, and the water is circulated through the filter installed on the cooler and the bottom surface. Then, the water is circulated through the water tank. And the water circulation was not smooth.

The bubble skimmer method using bubbles can be used in parallel with or independently of the above methods and has the following features in general.

1) Removes organic matter in seawater in the form of bubbles using air bubbles of millimeter size by air inflow through a venturi tube.

2) Air bubble generation plays a role both of collecting organic matter in seawater and supplying dissolved oxygen.

3) Dissolved oxygen supply ability using general air is not large, and in some cases, air bubbles are generated using oxygen.

However, the conventional bubble skimmer has a bubble size of several millimeters or more, so that the ratio of the surface area per volume is not high, so that there is a limit to the collection ability of the organic matter and the ability to supply dissolved oxygen. This is not suitable for large aquariums or farms with high breeding density, which require faster organic matter collection capability and dissolved oxygen supply capacity.

Korean Patent Laid-Open Publication No. 10-2012-0059666 aims to give a microbubble effect to a water treatment method using a microorganism carrier. Conventionally, in the method of water treatment of activated sludge by the aerobic characteristic of a conventional biological reactor, a system for removing organic substances dissolved in water under a bubbling condition of a large water droplet is very large in air bubbles, In order to solve the problem that the area of contact with water is small and the buoyant force is large and the contact time with water (liquid) is short, it is difficult to obtain a sufficient water treatment effect. Therefore, the application is based on the fact that a microorganism carrier exists in contaminated water When micro bubbles with a diameter of 100 micrometers or less are supplied to contaminated water in the state of micro bubbles, the micro bubbles of the micro bubbles are completely dissolved in the water due to the action of surface tension, and dissolved oxygen (DO) It is possible to maximize the water treatment efficiency by the microorganisms existing in the microorganism carrier, Hydroxy radical (-OH), which has strong oxidative power when bubbles disappear due to the self-pressurizing effect, is processed by water treatment which can double the water treatment efficiency so as to decompose various kinds of harmful chemical substances present in the water, ≪ / RTI > However, the above-mentioned invention is limited to a water treatment process using a microbial carrier, and lacks a configuration for collecting organic pollutants and expanding the path of bubbles due to microbarks.

That is, in a seawater treatment method in an aquarium or the like, an efficient seawater treatment method is required in which a skimmer using bubbles is improved to more easily remove organic contaminants and increase dissolved oxygen amount.

Accordingly, in the seawater treatment system including the bubble skimmer 200 for the seawater treatment of the water tank 100,

The bubble skimmer 200 includes a micro bubble generator 300 for generating a micro bubble having a diameter of 1-100 μm. The present invention provides a water treatment system using micro bubbles.

According to the present invention, in the seawater treatment of an aquarium or the like, oxygen or air is supplied to the water tank in the form of micro bubbles to sterilize various bacteria distributed in the water, to supply dissolved oxygen required for the growth of the organism in the water tank, It is possible to simultaneously implement the role of a skimmer to remove harmful organic matter.

The present invention generates micro bubbles whose diameter is on the micrometer level, whereas conventional skimmers generate millimeter sized bubbles. The microbubbles have an increased bubble surface area for the millimeter-sized bubbles, thereby providing a strong adsorption force on the organic matter, thereby maximizing the organic matter removal efficiency and greatly improving the dissolved oxygen supply capability. Experimental results show a 400% higher dissolved oxygen supply rate than the millimeter size bubble.

In addition, the present invention can be expected to have a germicidal effect using active oxygen microbubbles. The above-mentioned active oxygen microbubbles were found to have a high disinfecting power of 99% or more within 1 hour for a concentration of one million or more bacteria per 1 ml, and it was confirmed that they do not require the addition of a fungicide, There is a harmless advantage.

That is, according to the present invention, in contrast to the conventional water tank system for seawater in which a sterilizer, a dissolved oxygen supplier, and a skimmer apparatus for removing organic matter are separately constructed, the system for sterilization, dissolved oxygen supply, Thereby improving the cost efficiency and maximizing the effect of removing organic substances and supplying dissolved oxygen by applying micro bubbles.
