TW201714819A - Emergency capsule for rapid oxygen enrichment and modification of water - Google Patents

Abstract

An emergency capsule for rapid oxygen enrichment and modification of water includes a water-soluble shell soluble in water and forming an interior space, a peroxide compound disposed within the interior space enclosed by the water-soluble shell, and a complexing agent mixed with the peroxide compound and disposed within the interior space. The mixture of the complexing agent and the peroxide compound contains 0.1-10 weight percent (wt%) of the complexing agent and 90-99.9 weight percent of the peroxide compound. Because the water-soluble shell slowly dissolves in water and the complexing agent neutralizes chemical substances and retards chemical reactions, the peroxide compound is able to slowly generate oxygen and remove the reduced halogens, while improving water quality and preventing occurrence of anoxic conditions.

Description

First Aid Capsule for Rapid Oxygenation and Modification in Water

The present invention relates to a capsule structure which can be used for rapidly increasing the degree of dissolved oxygen in water and improving water quality.

At present, aquaculture is a very important industry and one of the most important sources of protein intake by humans. In the process of developing economies of scale and improving unit production efficiency, to increase the unit production of aquaculture, it is necessary to increase the dissolved oxygen equipment in the water to increase dissolved oxygen and put a large amount of bait, so as to obtain the maximum harvest in the shortest time. However, during this operation, due to the eutrophication, residual bait pollution and fish excretion in the water, it will gradually accumulate, which will cause excessive changes of dissolved oxygen in the water, often with the occurrence of pan-pool (pan-tank) phenomenon. Fish died of lack of oxygen, causing serious economic losses. In the process of the pan-pool, hypoxia is the first visible phenomenon, which causes the fish to float and accumulate around the waterwheel due to lack of oxygen. If the dissolved oxygen is provided in a large amount within two hours, the mortality can be greatly reduced. The existing first-aid method is to pour hydrogen peroxide into water, which instantly produces a high amount of dissolved oxygen and can alleviate the anoxic syndrome. However, this method has the following shortcomings.

1. The pan-pool generally occurs at night. The unit of hydrogen peroxide is 30 kilograms. It must be moved to the bamboo pole in the middle of the night, and then the concentration of the aqueous solution of the double-oxygen solution is dispersed by the movement of the bamboo raft to achieve the purpose of dispersion. Since the weight of hydrogen peroxide is quite heavy, this practice is a potentially risky behavioral pattern in areas where manpower is aging.

2. The dispersion and reaction of hydrogen peroxide is very fast, and the problem of hypoxia can be solved temporarily, usually for two hours. If it occurs in the middle of the night, this action needs to be done once an hour, which is very labor-intensive and dangerous.

Inspected the patent case No. 403720 of the Republic of China on September 1, 1989, "Oxygen generator, carbon dioxide gas absorbent, live fish transport system and live fish transport method", which revealed that oxygen production The agent is coated with a solid peroxide and a peroxide by a cup method of moisture permeability (40 ° C, 90% RH) of 20 g / m 2 / 24 hours or more, and a moisture-permeable material that is impervious to water under normal pressure. Media. Further, the carbon dioxide absorber is a gas-permeable gas permeability (JIS P8117) of 0.1 to 3000 seconds / air 100 ml, and a gas permeable material impervious to water under normal pressure, packaging alkaline earth metal hydroxide and / or Made of oxides. Further, the live fish transport system is one in which an oxygen generating agent and a carbon dioxide absorbent are enclosed in a transport bag.

However, since the patent case can only be used for a small number of fish to be used, it cannot be used in an open, large-area, multi-water culture space, and it is not possible to disperse a large amount of oxygen molecules, and the scope of use is limited. Moreover, due to the faster reaction time during oxygenation, reactive oxygen radicals and halogens are additionally generated after the reaction, and the reactive oxygen radicals and halogens may cause a radical chain reaction when excessive, especially with important proteins and carbohydrates in the cells. Oxidation of lipids and nucleic acids, causing normal cell damage and loss of function, can also lead to DNA damage, causing mutations, cancer or chronic diseases, and even aging. Therefore, it is easy to directly destroy the cell membrane of the fish and damage the fish gill. Moreover, the rate of generating oxygen is fast, and the speed of oxygen consumption is also rapidly increased. Therefore, it is necessary to continuously supply the oxygen generating agent in a short time, so that it is also labor-intensive and time-consuming. Moreover, it can only carry out the reaction in the range of the water surface, and can not penetrate into the bottom layer of the water to increase oxygen and purify the water quality of the bottom layer.

In addition, the invention of the invention No. 200520683 of the Republic of China on July 1, 1994, "Methods for Applying Sodium Carbonate to Aquaculture Water Quality Control", discloses: including the following steps: (a) collecting test water quality; Further testing and analysis of the water quality of the pond to understand the state of the water quality of the pond; (b) comprehensively analyzing the data obtained in (a), and calculating and evaluating the optimal dose according to the volume of the pond and various environmental conditions; c) The preparation of sodium percarbonate (Na ₂ C ₂ O ₆ ) or sodium percarbonate as the main active ingredient is directly dissolved in the culture water in a solid state to react with water to produce hydrogen peroxide (H ₂ O _{2 ).} And sodium carbonate (N _a2 C _O3 ) or a preparation of sodium percarbonate solid or sodium percarbonate as a main active ingredient is first dissolved in a small amount of water to derivatize hydrogen peroxide and sodium carbonate, and then the solution is added to the culture water. It has the effect of decomposing harmful substances in aquaculture water such as ammonia, nitrite and hydrogen sulfide, and has low damage to water-producing substances and no drug residue, but the water quality control of the pool and the Pantang First aid does help.

The percarbonate produced by the patent in the previous case will also cause certain damage after contact with water or skin, so the damage to the fish is no less than the damage caused by the aforementioned invention No. 403720. Therefore, it is not ideal in use.

Moreover, the above-mentioned patents do not explicitly disclose the same technical features and effects as the present invention.

When in use, as shown in the second and third figures, when a fish pond is raised in a culture pond (A) and the state of hypoxia is present, the water in the culture pond (A) is usually dissolved in oxygen. The degree of bonding has been less than 3ppm. The first-aid capsule can be immediately put into the culture tank (A), and the quantity to be administered can be determined according to the amount of water in the culture tank (A), so that the dissolved oxygen saturation degree in the water of the culture pond (A) Preferably, it is between 5 ppm and 8 ppm.
