Description

Purification by environmental purification setting agent FOS and secondary pollution prevention system

In the past, purification of rivers, ponds, swamps, business establishments, domestic wastewater, etc. has been carried out by purifying wastewater using biological treatment [activated sludge treatment method] microorganisms.
However, the purification capacity is constantly changing depending on the pollution situation and the environment, and the purification capacity cannot be exhibited as expected. In addition, due to increased production and pollutants as designed for purification equipment, there are many places where the purification capacity is exceeded and the desired purification cannot be performed and no countermeasures can be taken.

On the other hand, scientific research on microorganisms has been actively carried out, and many types of bacteria with excellent purification have been announced. The purification ability is not fully demonstrated.

Removal of nitrogen, phosphorus, and heavy metals is not sufficient within the conventional technology and wastewater standard range, and the wastewater as it is tends to cause eutrophication and heavy metal pollution in rivers and seas.

Problems to be solved by the invention

There are many microorganisms in nature that can purify contaminated wastewater.
However, because the environmental conditions do not match, it will not be able to fully demonstrate its ability, and even it will not be able to exist. Therefore, the environmental purification setting agent FOS was invented.
The feature is 1) The dissolved oxygen can be increased by utilizing the water in the water and the soil.
2) Providing essential nutrients of microorganisms with minerals, vitamins and proteins.

Theory 1

Method for increasing dissolved oxygen When FOS is diluted with water, deuterium sulfide (D ₂ SO ₄ ) reacts and can occur as a phenomenon at the molecular level of water. Other molecules absorb energy and can be divided into indirect actions that react with the molecule.
Water molecules become unstable because they are excited or ionized and have extra energy. In the process of releasing this extra energy, the covalent bond of the target molecule may be broken to form two radicals. It is not necessarily the site that has absorbed the binding energy to be cut.
The energy excited or ionized from deuterium is first absorbed by water molecules in the aqueous solution, and thereafter, hydroxy radical (HO.), Hydrogen radical (H.), hydrated electron (eaq-), H ₂ , H ₂ O _2, etc. The radical or molecular product of Then, these active substances move through water and cause a chemical reaction with the target molecule to act.
Excitation energy ionizes or excites water molecules.
Water molecule ions (H ₂ O +) are very unstable and decompose within _10-15 seconds to yield HO. And H ₃ O +.
Electrons that jump out of the water molecule are trapped between other water molecules to generate eq−.
Hydrated electrons is the absorption coefficient in 715nm has an absorption maximum of 18500m-1 cm-1, the standard reduction potential in -2.9Mv, half-life in water of neutral at 2.1 × _10- 4 / s is there.
The radicals react
In addition to the neutralization reaction of
As a result, molecular products H ₂ and H ₂ O ₂ are produced. Therefore, two radicals of H. and HO. And two molecular products of H ₂ and H ₂ O ₂ and eq− are generated.
Scientific processes occur when they react with solutes in solution.
HO and H ₂ O ₂ have strong oxidizing power and react with organic substances to cause indirect action.
On the other hand, eq− has a reducing power. In aqueous solution
Therefore, eq-H · coexists at pH 4 to 9, and H · becomes an important reducing agent at pH 2 or lower.
The present invention exists in a stable form of PH1.4 in the form of deuterium sulfide (D ₂ SO ₄ ).
When sulfuric acid (H ₂ SO ₄ ) is used during excitation or ionization of sulfuric acid ion water molecules and energy reaction, sulfate ion (SO ₄ 2−) tends to be more ionic than OH− in water, Sulfate ions remain in the aqueous solution as they are, and OH- passes electrons to generate water and oxygen.
When deuterium is used to charge and perform the same action as water electrolysis, H + is released as hydrogen, while OH- changes to ions with a surface-active effect called negative hydroxyl ions. . In addition, an intermittent phenomenon in which hydroxyl ions are repeatedly generated and disappears constantly occurs, and as a result, negative ions are continuously generated. This hydroxyl ion acts on the hardly decomposed organic compound to make it harmless, and the heavy metal is oxidized.
Generation of dissolved oxygen Table 1 Fig. 1 Graph Reference ・ Since the initial dissolved oxygen was high at 8.49 mg / L for both ion-exchanged water and distilled water, it was decided to use after deaeration.
・ Increased dissolved oxygen was also observed in deaerated water. This may be due to a certain amount of air bubbles mixed during installation.
・ FOS was added, and the amount of dissolved oxygen increased rapidly.
・ FOS is considered to be very effective for soil improvement, remediation, and bacterial growth.
・ An oxygen electrode experiment was conducted at the same time, but the results showed good values, confirming that the liquid did not exist so far.
Can be confirmed.

Theory 2

Natural minerals are used for mineral elution. Normally, it is composed of oxides of minerals such as Ca, Si, Al, Fe, etc., but the biotite system has many types of minerals of 20 to 40 types. When this is dissolved and eluted in the FOS stock solution, it is dissolved in water as Al, Fe, Mg, K, P, Ti, Ca, Mn, and Na salts, their double salts, complex salts, or oxides and exists in an ionic state. . This mineral content works particularly favorably for microorganisms in microbial treatment (activated sludge process).

Activated carbon is used as a typical filter medium for nitrogen, phosphorus, heavy metal adsorption and decomposition methods. It is effective for adsorbing mainly adsorbing ability based on the fine pore shape, coloring, contaminants, waste gas, etc., removing it from the medium and purifying it. However, there is a limit to the adsorption capacity, and replacement, regeneration, etc. must be performed, and the period of use is uneconomical for an expensive period. This is very disadvantageous for purification costs.

This system solved the above problems using two kinds of minerals. One is a ceramic made by sintering diatomaceous earth at 1100 ° C, and it is a very efficient material with an ultra-porous and ultra-fine structure 5,000 to 6,000 times that of charcoal. Use quality coal together. Coal does not need to have particularly high heat calories, and ash components are eluted and processed into a porous material by treating a quality having no utility value as a heat source with FOS (environmental purification setting agent). The used FOS can be used as it is as a water purification agent. In the case of normal coal-based activated carbon production, it is treated with sulfuric acid, hydrochloric acid or the like. In addition, the acid is neutralized after use, but in the case of FOS, it is not necessary and can be used as it is as a wastewater treatment agent. Therefore, it is a great merit to reduce cost and prevent secondary contamination by chemicals.

This mineral material treated above is called FOSAC. FOSAC does not require frequent replacement as conventionally used activated carbon. Since it is worn and consumed about once a year, it is sufficient to replenish about 10% of the whole. Moreover, since the inside of this FOSAC maintains an internal temperature of 5-10 degreeC throughout the year, it is suitable also for a cold district. As a result, the environment is prone to bacteria. In addition, the honeycomb system such as crushed stones and plastics currently used has a large amount of biofilm, which clogs pipes and causes recontamination of rivers and the like.

Dissolved oxygen test Since the initial dissolved oxygen of ion-exchanged water and distilled water was as high as 8.49 mg / L, it was decided to use after deaeration. There was also an increase in dissolved oxygen in deaerated water. This may be due to a certain amount of bubbles being mixed. There was a sharp increase in the amount of dissolved oxygen after the addition of FOS. Simple purification device by FOSAC 1) Add FOS to water to be purified. Automatic operation by timer or manual 2) Pump up FOS treated water to tank. 3) FOSAC that has undergone FOS processing is contained in the tank. 4) Water treated with FOSAC is used or recycled as reclaimed water for further purification. 5) This system has a low replacement frequency like activated carbon, and can be replenished once a year. 6) Contamination purification of metal ions such as nitrogen, phosphorus and plating factory effluent is also possible. 7) Can prevent eutrophication. 8) It can purify water contaminated with fungicides, insecticides and pesticides. 9) Utilizing existing purification facilities, the purification capacity can be improved as compared with the past.
