The water purifying apparatus of the present invention for achieving the above object is a pipe-type zinc alloy core tube, a silver alloy copper coil wound around its outer periphery of the zinc alloy core tube along the longitudinal direction, and on the outside of the zinc alloy core tube. Inside the voltaic battery, which is provided with a cathode tube installed at regular intervals, a far-infrared ceramic tube which is installed at a predetermined interval on the outside of the cathode tube, and emits far infrared rays, and is fixed to both sides of the far-infrared ceramic tube and formed with a through hole. An assembly; The voltaic battery inner assembly is accommodated and bound therein, and both ends of the voltaic battery assembly are formed to include a voltaic battery assembly including an outer case protruding a predetermined length outward from the side support.

In this configuration, the water purifying device using the voltaic battery of the present invention is installed in a place where the fluidity of water is small, and has a function of inhibiting the production of green algae (moss), sterilizing and inhibiting the production of bacteria, and removing odors. It forms as a salt, removes the precipitate, and activates water by the far-infrared ceramic effect.

Between the internal components of the water purifying device of the present invention is provided with a plurality of anti-tip clip ring to have a stable coupling structure between the internal components, in particular when the water in the tank when used by binding to the outlet or inlet of the circulation pump for the circulation of water Can be purified more effectively.

For reference, the electrochemical reaction theory applied to the water purification device of the present invention will be described first.

Generally, the electrochemical reaction is in the kinetics as base the reduction decomposition of the node electrode (Anode) H ⁺ H ₂ O ions are delivered ground to increase with the density of a non-reduction of the H ⁺ ion been followed by the H ⁺ and OH ^- Ions are produced.

That ^{_{is, H 2 0 + 2e - →}} H + + 2OH -

In this way, the reduction reaction is increased, the concentration of hydrogen ions H ⁺ is increased, the pH is increased on the cathode (Cathode) electrode surface, and the ORP (redox potential) is negative.

In the Stability Field Water, water is reduced to H ₂ when water is used as an oxidant, and water is oxidized to O ₂ when used as a reducing agent.

Chemical species that can withstand water must have a reduction transition between the limits corresponding to the above two processes. In addition, the water to be reduced is rapidly reduced to H ₂ and the oxidant is rapidly oxidized to O ₂ so that it does not exist in the liquid state.

A region that is thermodynamically stable to oxidation and reduction of water is represented by a region of a reduction potential or a pH value, and there is a Pulbeich diagram, which is shown in FIG. 4 of the present invention.

On the other hand, when looking at the voltage generation process of the voltaic battery, as shown below (-400mv) ~ (+ 800mv) and generates a total voltage of 150mv to sterilize bacteria in the fish tank or aquarium and suppress the generation of green algae prevent.

Negative pole: Zn → Zn ²⁺ + 2e ^- EO oxidation = (-400mv)-(-800mv)

Positive ^{electrode: Cu 2+ + 2e - → Cu} EO reduction = (+ 400mv) ~ (+ 650mv)

(All): Zn + Cu ²⁺ → Zn ²⁺ + Cu EO Total = 150mv

Germ sterilization, production suppression and odor removal are up to -800mv of water ORP (redox potential) due to the electrochemical reaction by internal voltaic battery and Infrared Radiation wavelength from ceramic member. However, microorganisms are killed by a potential difference of only a few mv, so they have a sterilizing function to kill microorganisms and prevent the occurrence of bacteria at the source. In addition, components such as ammonia (NH ₃ ), ammonia nitrogen, hydrogen sulfide (H ₂ S), and nitrate nitrogen are suppressed and sublimed (vaporize) to remove odors.

Hereinafter, with reference to the accompanying drawings based on the above-described principle will be described in detail a preferred embodiment of the water purifying apparatus according to the present invention.

For reference, in the drawings, an arrangement example of a voltaic battery assembly 20 performing a water purification function in the present invention and a circulation pump 10 coupled thereto is shown together in one tank for convenience.

Hereinafter will be described the experimental example applied to the water treatment device of the present invention in the tank.

Experimental Example 1

In the present embodiment, using an ordinary household aquarium, two aquariums with the water purification device of the present invention and two tanks (hereinafter referred to as 'control aquariums') are prepared to breed the same number and the same kind of ornamental fish, The difference in change was observed.

The aquarium is 86cm wide, 40cm high, 30cm high, and has a bottom of about 3cm of sand, and a voltaic battery assembly 20, which is a water purifying apparatus of the present invention, is installed in the first example of FIG. 3A. In the illustrated form, that is, installed two voltaic battery assembly 20 of the present invention, one of the two was installed about 1cm under the sand, the other was installed in the water.

The water used in the aquarium was filled with 150ℓ of groundwater used as a constant water in the tank, and the chlorine was volatilized by operating a bubble generator and a water temperature control heater for 1 day, and the water temperature was controlled to be maintained at about 26 ° C. to create an environment suitable for ornamental fish breeding. .

In order to reduce the experimental variables and to facilitate the observation of the results, the filter for filtration was removed and no plants or decorations were used. The fish species were tropical fish, 5 silver barbs, 4 silver giants, 5 silver sharks, and perogrami Three dogs and a total of 17 dogs were used.

Changes in water quality include cultivation of tropical fish under the above conditions, observing tropical fish activity, sampling samples at regular intervals, conductivity, turbidity, redox potential (ORP), pH, hardness, COD, chlorophyll, etc. Was measured and analyzed, and the results are shown in Table 1 below.

In addition, it is shown in Figures 5 to 9 the trend of the time-phase change in each measurement item.

<Table 1> Changes in Aquarium Water Quality over Time

a) Voltaic battery assembly installation aquarium

Date range COD (mg / l) Turbidity (NTU) Conductivity pH ORP (mV) Total Nitrogen (mg / ℓ) Total phosphorus (mg / ℓ) Hardness (mg / ℓ) Chlorophyll (mg / ㎥) Zinc (mg / l) 0 0 0.71 145.8 7.53 -49.8 - - 92.5 - - 6 7 0.72 180.8 7.56 -50.5 - - - - - 14 16 0.73 222.2 7.53 -52.0 - - - - - 20 20 0.94 265.3 7.47 -31.3 - - - - - 27 34 1.43 297.6 7.47 -33.2 - - - - - 33 36 1.67 323.7 7.43 -39.1 25 6 146 4.6 0.8

b) control aquarium

5 is a graph showing the change of time of COD.

Referring to the figure, the COD change tends to increase with time in both aquariums, which is due to the excess feed supplied to the aquarium and the excretion of other microbial fish, including bacteria and algae in the water. However, in about a month of experiments, it can be seen that the installation of voltacell has the effect of reducing the concentration of oil in the water since it is twice as large as that of the control aquarium without the voltacell.

FIG. 6 is a graph illustrating a change in time of turbidity.

The turbidity change is shown that, while the aquarium with the voltacell is largely unchanged during the experiment, the control aquarium was similar to the aquarium with the cell at the beginning of the experiment, but there was a sharp difference after about 15 days. It is happening.

Turbidity-inducing substances, such as aquariums, are generally charged with organic and inorganic colloidal particles of about 1 μm or less, and colloidal particles are highly stable due to their size and charge, and therefore rarely precipitate. . Colloidal particles are classified into hydrophilicity and hydrophobicity according to the degree of affinity with water. In general, inorganic colloidal particles have a hydrophobic charge, and some organic compounds appear to be dissolved in water but do not form a true solution. It exists as a hydrophilic colloid. The turbidity-inducing substance in this experiment is judged to be mainly composed of a mixture of hydrophilic particles and a few hydrophobic particles, unlike general natural water having excellent hydrophobic colloidal particles. These hydrophilic colloidal particles (organic) are combined with heavy metals to form insoluble salts and tend to be precipitated and removed. Therefore, the turbidity of the aquarium where voltacells are installed is relatively constant.

Figure 7 is a graph showing the change of the time period of pH.

As shown in the figure, the time-phase change in pH was relatively constant when Voltacell was installed, whereas the control aquarium gradually increased in pH. This increase can be explained by the final concentration change of chlorophyll shown in Table 1 above. Chlorophyll is a common component of all freshwater algae and is used as an indicator of algae development. Algae are carbon-assisted vegetable aquatic organisms that grow rapidly with appropriate sunlight, temperature, and nutrients, and the aquarium used in these experiments usually meets these conditions. When the photosynthetic activity of the aquatic bird hwalbalhal inorganic carbon in HCO ₃ ^- or CO ₃ ^- absorbing and OH ^- sikimeuro caused the increase of water pH. Therefore, the increase in pH of the control aquarium is caused by the increase of algae, and the aquarium with voltacells is a factor that keeps the pH constant due to the suppression of algae generation, which is a major factor in causing turbidity, and the removal of a large amount of generated algae. .

On the other hand, in the case of the total nitrogen and total phosphorus, as shown in the <Table 1>, the control aquarium was measured to be high, which is compared with the ORP change characteristic graph shown in Figure 8, the control aquarium is generally a strong aerobic atmosphere (especially After 20 days, oxidation was promoted from organic nitrogen and phosphorus, which are essential factors for algae production, to inorganic nitrogen (NH ⁺ , NO ₂ , NO ₃ ) and inorganic phosphorus (PO ₄ ^3- ).

Fig. 9 is a graph showing the transition of electrical conductivity, which shows the concentration of the ionic solute solids contained in water, and measures the ability of the solution to flow current. The difference in conductivity between the two aquariums was substantially absent, mainly due to the increase in inorganic pollutants in the water, since soluble organics without charge were not measured in conductivity, regardless of their amount.

Experimental Example 2

This experiment is to install the Voltacell in one aquarium under the similar environmental conditions as the experiment of Experiment 1 described above, and to confirm that the inside of the fish tank was clearly contaminated while breeding ornamental fish for one month by contrasting the other aquarium It is an experiment to observe the change of water quality in the aquarium where Voltacell was installed and the effect of water quality improvement on the water that is already contaminated by removing the Voltacell installed in the Aquarium and then moving to the control aquarium for 60 days. .

10 to 12 are graphs showing changes in time of change in COD, turbidity, and chlorophyll, respectively;

As shown, in the aquarium where the voltaic cell was installed and removed, the aquarium remained constant with little change in the water quality, indicating that the electrical and chemical changes in the water quality caused by the installation of the cell have residual properties. In addition, it can be seen that there is an effect of improving the water quality when applied to the water quality that has been considerably polluted in the aquarium where voltacell is moved. This change is ultimately closely related to the turbidity removal and algal growth suppression mechanisms mentioned earlier.

Experimental Example 3

Example of the present experiment is a zinc elution test of voltacell, an experimental example for measuring the change in pH and zinc concentration of water when exposed to voltacell in water for a long time, Figure 13 and Figure 14 shows the trend of the change over time As shown.

The water used in this experiment was purified water that had undergone activated carbon and ion exchange resin, and the experiment was conducted without rearing ornamental fish.

The pH was low due to the high concentration of ionic substances in the underground water, and the pH was low due to the increase of H ⁺ by ion exchange during the purification process.However, the water quality reached near neutral due to intermittent agitation and contact with the atmosphere. Since then, it has remained relatively constant.

The concentration of zinc increased in the form of a logarithmic function over time. Even though the solubility of zinc in the high pH range of the aqueous solution tended to decrease, the concentration of zinc continued to increase, resulting in continuous dissolution from voltacells in the metal-stable state. It can be seen that. However, in the 50-day experiment, the concentration of zinc tends to converge to about 4 mg / l.

Zinc is classified as an aesthetically affecting substance by water quality standards, and the water quality standards of zinc in the United States and Japan, including Korea, are also regulated at 1 mg / l, and WHO is regulated at 5 mg / l.

It is known that zinc-containing water has an unpleasant taste and gives an unpleasant odor and greasy feeling when boiled, causing vomiting, dehydration, lethargy, nausea, and zinc chloride. Therefore, if a large amount of long time pollution is left, there is a risk of toxic reactions. However, in general, zinc is not treated as a strict regulatory item in terms of water quality standards, and research shows that water used as drinking water is necessary for maintaining human health, especially trace metals such as iron, zinc, copper, and selenium. As it is being published, the concentration of dissolved zinc is generally not at a risk to aquatic or higher animals.

As described above, the present invention, when installed in a fish tank or a pond, is a very useful device having both growth suppression and removal of microorganisms in a tank, sterilization, water purification function, and odor prevention function. It is very effective in improving the water quality of ponds, lakes, reservoirs, and the like, and is particularly effective in removing nitrogen and phosphorus, which can be used to improve the quality of fish farms and fishing grounds.
