Abstract

PROBLEM TO BE SOLVED: To accelerate the dissolving of aluminum by an ionization tendency function and to acceleration the purifying function for water quality by an aggregation effect, by allowing the aluminum to contact with a subject water in a form combined with stainless steel, etc. SOLUTION: When the aluminum and the stainless steel are connected in a subject water, the aluminum large in ionization tendency is liable to dissolve and aluminum hydroxide is eluted into the subject water. The impurities in the water are sunk to the bottom of the water because this aluminum hydroxide causes a coprecipitation function with the org. matter and a soil as impurities in the water by a coherent effectiveness. The sunk impurities exhibit the purifying function by accelerating a decomposing function of microorganisms at the bottom of the water. At this time, solubility is increased and a large effect is exhibited by using an aluminum foamed material, etc., large in the surface area of the aluminum (alumina). The foamed aluminum becomes the best living site of the microorganisms and higher effect is expected because the foamed aluminum is porous and has a capillary action.

2. Description of the Related Art Today, there is a strong concern that the water quality of rivers and lakes will decline. Deterioration of water quality is a macroscopic manifestation of one of the destructions of the environment of the earth. Has significant effects on human life. Originally, a wide variety of aerobic microorganisms exist on the earth, and feed on nitrogen, carbon, and phosphorus compounds contained in spoiled food, human waste, animal carcasses, and domestic wastewater, which are the main causes of water quality degradation. As a source, it ultimately reduces these to nitrogen, carbon dioxide, etc., and river water is naturally purified by the self-cleaning action of these microorganisms.However, the concentration of population in cities, destruction of vegetation, Changes in the ecosystem, such as by spraying, have slowed the growth of these microorganisms and the resulting self-purification, leading to today's situation.

Problems of the prior art Fundamental means for water purification include restoring ecosystems by dispersing the population, providing sewage systems, stopping the use of forest restoration pesticides, industrializing, and completely purifying domestic wastewater. That is.
However, it takes a long time to carry out these measures, and it is not possible to meet the demand in a hurry, and it is difficult to carry out these measures in connection with the economy such as complete purification of industrial and domestic wastewater and discontinuation of pesticide use. It is also a matter. On the other hand, however, the current water quality improvement projects for rivers and lakes are all targeted treatments, and there is no great expectation.
Therefore, this is the reason why it is said that there is nothing but a quantitative limit.

[0004]

In view of the above-mentioned circumstances, the present invention is a combination of aluminum and stainless steel or the like, and by applying the ionization tendency (Volta line), it is simple and has a low equipment cost. It is intended to provide an effective water purification method applicable to the ocean, lakes, ponds, drains and the like. Another object of the present invention is to provide a water purification method that is useful for preventing water quality in fish ponds, cages, live fish tanks, and aquariums (gold fish and tropical fish breeding tanks).

[Means for Solving the Problems]

Concept The present invention based on the above concept is effectively constituted by the simplest method applying the volta line of metal.

This is a method in which aluminum and stainless steel or the like are combined in the target water to promote the dissolution of aluminum (alumina) by the ionization tendency action and the water purification action by the agglomeration effect.

Ionization tendency (Volta line) A line in which a metal emits electrons to become an ion and tends to be dissolved in a solution, that is, a large and small ionization tendency is arranged in order for the metal. In 1800 A, Volta just discovered a series corresponding to this, so it is also called Volta string. (Chemical dictionary)

Uses In addition to water purification of aquariums for appreciation, ponds, rivers, oceans and fishponds, cages, pools, live fish tanks, etc., it is useful for preventing and improving water quality deterioration of drainage structures, that is, for purification of the sea and rivers. It does not require power and can be widely used as an energy-saving and water quality improvement means.

Application form The present invention, in the target water due to the ionization tendency of the metal,
This is an extremely simple method of promoting the dissolution of aluminum (alumina) and purifying it. That is, when aluminum and stainless steel are connected in water, aluminum having a large ionization tendency is easily dissolved, and aluminum hydroxide is dissolved in the target water. Even if aluminum and iron are combined and connected, the aluminum melts. The same situation occurs when aluminum and lead are connected. Ions flow from aluminum to stainless steel, iron, etc. even if they are not directly connected to each other, that is, at intervals like an electrode plate. Therefore, in the target water, the effect can be expected immediately if a method of opposing the metal using the ionization tendency is used. In order to further increase this effect, a foaming material of aluminum or the like having a large surface area of aluminum (alumina) is used, so that a large effect can be obtained because the solubility is large. Further, since the aluminum foam material is porous and has a capillary action, it becomes a perfect habitat for microorganisms and further effects can be expected.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is a means using the ionization tendency of a metal, which is a combination of the metals, that is, when aluminum (alumina) is dissolved in an aqueous solution, aluminum hydroxide is generated. Impurities in the water are settled at the bottom of the water because they cause coprecipitation with organic substances and dirt in the water with a cohesive effect. Therefore, the precipitated impurities promote the decomposition action of the microorganisms on the bottom of the water and the purification action. Since the aluminum foam material is porous and has a capillary action, it becomes a perfect habitat for microorganisms and also promotes a biological action. Also, due to the action due to the ionization tendency, the aluminum foam becomes a cathode, and since it holds hydrogen, if it is placed above the water surface by using the capillary action of the aluminum foam, it will react with oxygen in the air and become submerged in water. Dissolution of oxygen gas becomes easy. Therefore, the water quality is purified and improved by the combined action of the cohesive effect, the biodegradation effect, and the chemical reduction effect. As a method that can be considered when the economical effect is required by using the above-mentioned purification method using a hydrophobic porous capillary material which is not a metal, one side of the hydrophobic porous capillary material made of fibers and If alumina powder is applied to both sides using a binder such as Almatex to form an alumina sheet, a sufficient effect can be obtained as a substitute for the aluminum foam material. In any case, it is important to use materials such as stainless steel and iron, which have a low ionization tendency, in addition to aluminum, which has a high ionization tendency.
