Description

201242908 VI. Description of the invention: [Technical field of inventions: j Technical field] The present invention relates to a wastewater treatment method for factory wastewater, household drainage, restaurant drainage, and various other drainages that can be used together with thermal energy. [Winter Good 3] In the past, there has been a proposal for a drainage treatment method using electrolysis (Patent Document 1). The drainage treatment method has a mixing step of mixing the drainage water and the oxidant-containing water to treat the pollution evaluation index to about Oppm, and electrolyzing at least a part of the water to generate a residual gas, and the treatment water for generating the residual gas It is mixed with drainage water as oxidant-containing water. The drainage treatment method has a "mixing step" of mixing the drainage water and the oxidant-containing water to treat the pollution evaluation index to about Oppm, and causing the pollution component of the drainage to encounter, collide, react with the oxidant and oxidatively decompose so that the pollution evaluation index is about Oppm. Thereby, it is possible to suppress accumulation of contaminating components in the processing system, and there is an advantage that the processing can be made more stable than ever. Having said that, there is still a problem that the gas volatilized from the liquid phase to the gas phase during electrolysis cannot be more fully utilized. [Patent Document 1] JP-A-2011-111.67 [Abstract]: Disclosure of the Invention Problems to be Solved by the Invention 201242908 It is therefore an object of the present invention to provide a wastewater treatment method which can more fully utilize the gas generated during electrolysis. Means for Solving the Problems In order to solve the above problems, the following technical means are employed in the present invention. (1) The wastewater treatment method of the present invention is characterized by comprising: a step of generating a gasification hydrogen gas by reacting hydrogen gas with a gas gas generated by electrolysis at the time of electrolysis to generate a vaporized hydrogen gas; and dissolving the gasification hydrogen gas a gasification hydrogen gas dissolving step in the drainage; and discharging the water having dissolved the vaporized hydrogen gas to the electrolysis mechanism. Here, the electrolysis mechanism may be in the form of a diaphragm or a diaphragmless method. The above-mentioned hydrogen gas may be produced by an electrolysis mechanism using a hydrogen cylinder, or may be supplemented with a hydrogen cylinder to the insufficient portion of the electrolysis mechanism. Since the drainage treatment method has a step of generating a vaporized hydrogen gas by reacting hydrogen gas with a gas generated by electrolysis at the electrolysis mechanism to generate a vaporized hydrogen gas, the hydrogen gas reacts with the gas to generate a vaporized hydrogen gas. Here, since the vaporization hydrogen gas generates the following large reaction heat generation, the reaction heat can be utilized as heat energy. 1/2C12 (gas) + 1/2 Η 2 (gas) - > HCl (gas) + 92.3 kJ / mol, because of the gasification hydrogen gas dissolution step of dissolving the aforementioned hydrogen sulfide gas in the drainage, the gas The hydrogen gas can be electrolyzed in the water and mixed with gas ions and hydrogen ions in the water. Then, since the water having dissolved the vaporized hydrogen gas is sent to the electrolysis mechanism, the gas (Cl2) is generated on the anode side by electrolyzing the drain containing the gas ions by the electrolysis mechanism. Here, the gas (Cl2) is volatilized from the drainage to become gas, 201242908 or reacts with water to form a sub-gas (H〇C1) 3 ch + H2〇HC1 + HOCl to hunt the sub-gas, pollution in the drainage The ingredients (organic ingredients, etc.) are oxidized and decomposed to purify. Moreover, the drainage is decomposed and purified by the direct oxidation of the anode. Like the chemical reaction formula of chlorine and water, the chlorine (ci2) in the drainage reacts with water to form hypogas (HOC1) and hydrochloric acid (HC1). ), and by increasing the aforementioned hydrochloric acid, the pH tends to be acidic. Therefore, due to the decrease, the sub-gas acid (H〇cl) is formed into a gas (CL) and is easily volatilized by the drainage. (2) The drainage treatment method differs from the above in that the gas generated on the anode side is electrolyzed by the diaphragm electrolysis mechanism. In other words, the wastewater treatment method includes a step of generating a hydrogenation gas by reacting hydrogen gas with a gas generated on the anode side when electrolyzed by a diaphragm electrolysis mechanism to generate a vaporized hydrogen gas, and dissolving the vaporized hydrogen gas in the drainage water. The gasification hydrogen gas dissolving step, and discharging the water having dissolved the vaporized hydrogen gas to the aforementioned diaphragm electrolysis mechanism. Here, the hydrogen gas may be formed on the cathode side of the diaphragm electrolysis mechanism using a hydrogen cylinder, or may be supplemented with a hydrogen cylinder to the insufficient portion of the cathode side of the diaphragm electrolysis mechanism. Since the wastewater treatment method has a gasification hydrogen gas generation step of reacting hydrogen gas with chlorine gas to generate a vaporized hydrogen gas, hydrogen gas reacts with chlorine gas to generate a gasification gas gas, and the gas gas system is electrolyzed by a diaphragm electrolysis mechanism. Produced on the anode side. Here, since the vaporization hydrogen gas generates the following large reaction heat generation, the reaction heat can be utilized as heat energy. 1/2C12 (gas) + 1/2 Η 2 (gas) - HC1 (gas) + 92.3 kJ / Moer 201242908 Further, because of the gasification hydrogen gas dissolution step of dissolving the vaporized hydrogen gas in the drainage, the reading is performed. The hydrogen gas can be electrolyzed in the water to hold the gas ions and hydrogen ions in the water. Then, since the drain water in which the vaporized hydrogen gas has been dissolved is sent to the above-described diaphragm electrolysis mechanism', the gas containing the gas ions is electrolyzed by the diaphragm electrolysis mechanism (ci2) to be burned at the anode. Here, the gas (4) is volatilized in the drainage to become an air gas or reacts with water to form a secondary gas (Η〇α).

Cl2 + H2〇 — HC1 + HOC1 With this gas, the polluting components (organic components, etc.) in the drainage are decomposed and purified. Further, the drainage is decomposed and purified by the direct oxidation of the anode. Here, as in the above chemical reaction formula of gas and water, the gas (C丨2) in the wastewater reacts with water to form a sub-gas acid (HOC1) and hydrochloric acid (Ηα), and the hydrochloric acid tends to be acidic on the side. Therefore, due to the drop in pH, the environment in which the sub-gas acid (H〇cl) becomes gas (Cl2) is easily volatized by the drainage. (3) It is also possible to have an energy generating mechanism that uses lime and water to generate heat of reaction, and heats the hydrated lime generated by the reaction of the quicklime and water to be decomposed into money and water, and The regenerated lime is in contact with the newly supplied water to continue the reaction, and the heat generated by the reaction of the vaporized hydrogen gas is used as an auxiliary energy for regenerating the quicklime. When so configured, the heat energy generated by the wastewater treatment method can be utilized for the heat of the supplementary energy generating mechanism. Here, the reaction between the quicklime and the water produces the following reaction to generate heat.

CaO + H2 〇 - Ca (OH) 2 + 64 kJ / Moule 201242908 Then, the energy generating mechanism has the following functions. (A) Since the energy generating mechanism decomposes the slaked lime generated by the reaction of the quicklime and the water into lime and water vapor by using quicklime and water to generate heat (as a heat source) Use) or water vapor (as power utilization) as energy utilization. In addition, since the regenerated lime is brought into contact with the newly supplied water to continue the heat generation of the reaction, the reaction heat generated by chemically changing the mature lime by reacting the quicklime with water is used for the temperature rise and decomposition of the slaked lime. Continuously gain energy. Here, although the heavy fuel or gas from the fossil fuel is burned to become carbon dioxide or the like and the original fuel disappears, the energy generating mechanism can continuously react the chemical structure between the quicklime and the slaked lime while changing. (B) When the slaked lime is heated to a decomposition temperature of 580 ° C or more by externally supplying insufficient heat, the quicklime and slaked lime are stored to supply water and the "reaction tank" for generating steam is maintained at the decomposition temperature of the slaked lime 58 The high temperature above 〇〇c, whereby the quicklime and slaked lime can continue to be a seamless reaction. The sump can also mix quicklime and slaked lime. (C) The water vapor generated by thermal decomposition of the slaked lime is used as energy, and the turbine can be rotated by pressurizing the water vapor generated by thermal decomposition at a high temperature to generate electricity. Since the decomposition temperature of slaked lime is 58 〇〇c, high-temperature water vapor can be obtained. Here, in addition to the water vapor generated by the decomposition of the slaked lime Ca(0H)2, the water vapor generated by the evaporation of the heat generated by the reaction of the raw lime CaO and the water HsO may be used. 201242908 (D) By using the heat generated by the reaction generated in the foregoing as a heat source, heat can be taken out from the peripheral wall of the "reaction tank" (for example, a liquid or the like) in which the quicklime and slaked lime are stored. (E) When the water is supplied as the water, the water can be removed while the energy is being removed. That is, the drainage relies on the exothermic reaction with the quicklime, partially evaporating into water vapor, and a part of it is combined with the quicklime to chemically change the mature lime. The slaked lime is separated from the quicklime at a high temperature to become steam. Then, the contaminated components in the drainage, especially the organic components, are thermally decomposed and purified by exposure to high temperatures. (4) Sodium hydroxide may also be mixed in the aforementioned quicklime. When so constituted, the heat of reaction of the sodium hydroxide can be used as the heat energy together with the heat generated by the reaction of the lime to change the mature lime. Namely, since the sodium hydroxide lattice is broken and further sodium ions are stabilized by the ionized water, the following heat of dissolution is generated.

NaOH (solid) + H20 - Na + + 0H_ + H20 + 44.5 kJ / Mo (5) Iron can also be mixed in the aforementioned drainage. In such a configuration, the iron mixed in the drainage reacts with the dissolved oxygen and water, and releases heat to raise the temperature of the water, thereby constituting an environment in which the gas and hydrogen are easily volatilized. The chemical reaction formula can be considered as follows. Since there are various expressions regarding the heat value itself, it is described herein as heat in the following formula. 4Fe + 3 〇2 ~>2Fe2〇3 + heat 4Fe+2H20+302-4FeOOH+ heat

Fe+3/2H20+3/40 broad Fe(OH)3+ heat Effect of the invention 201242908 The present invention has the constitution described above as #, +.a^, and has the following effects. When the D body is generated, the reaction generates heat and heat energy to use the energy, so it can be used for the process. x 仏 can be more charged/knife to use the water discharge treatment method using the gas generated during electrolysis. [Implementation of Cold Mode] BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described. (Embodiment 1) The main part of the left side of the figure is shown in the 'Drainage treatment method package 3 of the embodiment. The gasification filament formation step is the hydrogen emulsion 3 generated by the Ί*12 when the diaphragm electrolysis mechanism 1 is electrolyzed. The gas 5 generated on the anode side 4 reacts to generate chlorine, and the hydrogen sulfide gas is dissolved in the drain (high-concentration waste liquid 7). Thereafter, the cold-dissolved hydrogenated gas 6 is sent to the above-described diaphragm electrolysis mechanism 1 and the waste discharge pipe D is dispensed in the middle of returning the drain having the hydrogen chloride gas 6 back to the diaphragm electrolysis mechanism 1. Between the cathode side 2 and the anode side 4 of the diaphragm electrolyzer described above, the exchange membrane 8 is provided as a separator. Further, in the reaction tank of the hydrogen gas 3 and the chlorine gas 5, a heat source 1〇 for starting the mutual reaction is provided. Further, the hydrogen gas 3 is generated on the cathode side 2 of the diaphragm electrolysis mechanism ,, and is supplemented with a hydrogen cylinder (not shown) or a hydrogen cylinder to the insufficient portion of the cathode side 2 of the front ram mechanism 1. Electrolysis Next, the use of the wastewater treatment method of the embodiment will be described. This drainage treatment method has a method of generating hydrogen gas by reacting the hydrogen gas 3 with the gas 5 generated on the anode side 4 during electrolysis with a separator and an electrolysis mechanism! The hydrogen chloride gas generating step of the hydrogen gas 6 causes the argon gas 3 to react with the gas gas 5 to generate the vaporizing hydrogen gas 6. Then, since the vaporized hydrogen gas 6 is generated to generate a large reaction heat generation according to the following formula, the reaction generates heat as heat energy to utilize energy, and has an advantage that the gas generated at the time of electrolysis can be more effectively utilized (refer to the embodiment). 2). 1/2C12 (gas) + 1 / 23⁄4 (gas) - > HCl (gas) + 92.3 kJ / mol, and a gasification hydrogen gas dissolving step for dissolving the vaporized hydrogen gas 6 in the drainage, which can be The argon gas 6 is electrolyzed in the water to be mixed with gas ions and hydrogen ions in the water. Then, the drain having the vaporized hydrogen gas 6 dissolved therein is sent to the above-described separator electrolysis mechanism 1, and the gas containing the gas ions is electrolyzed by the diaphragm electrolysis mechanism to generate gas (Cl2) on the anode side 4. Here, the gas (Cl2) is volatilized in the drainage to become the gas 5 or reacts with water to form a sub-gas (HOC1).

Cl2 + H20 — HC1 + HOC1 With this gas, the polluting components (organic components, etc.) in the drainage are decomposed and purified. Moreover, the drainage is decomposed and purified by the direct oxidation of the anode. Further, as in the above chemical reaction formula of gas and water, the gas (cl2) in the drainage reacts with water to form a sub-gas acid (HOC1) and hydrochloric acid (HC1), and the hydrochloric acid tends to be acidic on the side. Therefore, since the pH is lowered, it becomes an environment in which the sub-gas acid (H〇c丨) becomes gas (C) 2) and is easily volatilized by the drainage. (Embodiment 2) As shown in the main right side of Fig. 1, there is an energy generating mechanism 13 which generates reaction heat by using quicklime 11 and water (tap water w) and 201242908 borrows the above-mentioned quicklime π and water. The slaked lime 12 produced by the reaction is heated to be decomposed into quicklime 11 and water vapor, and the generated heat is continuously generated by bringing the regenerated quicklime n into contact with the newly supplied water. The inside of the tank is stirred by a motor crucible. The energy generating mechanism 13 generates heat by reacting the quicklime 11 with water to produce the following reaction.

Ca0 + H20 - Ca(OH) 2 + 64 kJ / mol. Then, heat generated by the reaction of the cesium chloride gas 6 of the first embodiment is used as the auxiliary heat energy for regenerating 1:1 of the quicklime from the slaked lime 12. Here, clean tap water is used as water' and accumulation of pollution such as when using drainage is not generated. In the reaction zone of the quicklime 11, water and slaked lime 12, the waste discharge pipe is connected. The Hi-energy generation mechanism 13 supplements the thermal energy for regenerating the quicklime 11 by using the thermal energy (reaction heat generation) of the hydrogen chloride gas 6 generated by the drainage treatment method of the first embodiment. Further, by supplying water, the quicklime 11 and the cooked lime ash 12 become integrated, and the quick-release reaction of the quicklime 11 into the slaked lime 12 and the reaction of the slaked lime 12 to regenerate the quicklime 11 continue. Further, the energy generating means 13 generates electric power by rotating the turbine by the steam generator 14 by decomposing the steam generated by the water supplied by the pressurized water or by decomposing the steam generated by the slaked lime 12 (decomposition temperature 58 〇 qC). Therefore, the energy generating mechanism 13 obtains electricity. Further, sodium hydroxide 15 was mixed in the above-mentioned quicklime 11 crucible. Sodium hydroxide i 5 is first lattice-destroyed due to water (endothermic), and then sodium ions are stabilized (exothermic) with ions and water, and the heat of dissolution is generated by the difference in endothermic and exothermic heat.

NaOH (solid) + H20 - Na + + H + + H20 + 44.5kJ / Moule, therefore, can be combined with the reaction of the lime 13 chemically mature lime 12 to generate heat 201242908, using the dissolved heat of sodium hydroxide 15 as heat (vapor Power generation). (Embodiment 3) As shown in Fig. 1, in this embodiment, iron (not shown) is mixed in the drain. Therefore, the iron mixed in the drainage reacts with the dissolved oxygen and water and releases heat, so that the temperature of the water rises, and the atmosphere of the gas 5 and the hydrogen 3 is easily volatilized. The chemical reaction formula can be considered as follows. Since there are various statements about the calorific value itself, it is described herein as heat in the following formula. 4Fe + 3〇2 —^2Fe2〇3 + heat 4Fe+2H20+302—4Fe00H+ heat

Fe + 3 / 2 H 20 + 3 / 40 wide Fe (OH) 3 + heat (Embodiment 4) In the present embodiment, the electrolysis mechanism 1 is not a diaphragm type as in the above embodiment, but has no diaphragm method. As shown in Fig. 2, the wastewater treatment method according to the present embodiment includes: reacting the hydrogen gas 3 generated by the cylindrical cathode electrode 16 with the gas gas 5 generated by the cylindrical anode electrode 17 when electrolyzing without the diaphragm electrolysis mechanism 1 a hydrogen chloride gas generating step (vaporizing hydrogen gas generating region Z1) for generating a vaporized hydrogen gas 6; and a vaporizing hydrogen gas dissolving step for dissolving the vaporizing hydrogen gas 6 in the drain 7 (a gasification hydrogen gas dissolution region) Z2). Then, the drain 7 in which the hydrogen sulfide gas 6 has been dissolved is circulated to the aforementioned diaphragmless electrolysis mechanism 1. The diaphragmless electrolysis mechanism 1 itself also circulates with the pump P drawing the water inside. Therefore, the drain 7 will be purified. In the diaphragmless electrolysis mechanism 1, a cylindrical anode electrode 17 is disposed inside the cylindrical cathode electrode 16. In addition, the hydrogen gas 3 (the specific gravity of the air 12 201242908 is 0.07) which is volatilized above the electrolysis mechanism 1 is collected by the piping on the upper side, and the gas 5 (the specific gravity of the air is 2.49) is separately collected by the piping of the lower side by the specific gravity. . Then, the gas is merged, and the reaction source 9 is caused to start to react with each other by the electric heat source 10 to change it into a vaporized hydrogen gas 6. The vaporized hydrogen gas 6 which generates heat exotherm by the reaction of the hydrogen gas 3 with the gas gas 5 is conducted to the lower cooling water zone Z3, and the cooling water 18 (tap water) is heated to generate the vapor 19. Further, the vapor 19 is utilized as energy (for example, power generation). Then, the hydrogen sulfide gas 6 is dissolved in the drain 7. And it is sent to the electrolysis in the diaphragmless electrolysis mechanism 1. The hydrogen gas 3 is generated in the cathode electrode 16 of the diaphragmless electrolysis mechanism 1, but a hydrogen cylinder (not shown) may be used, or a hydrogen cylinder may be used to supplement the insufficient portion of the cathode electrode 17 of the diaphragmless electrolysis mechanism 1. Next, the state of use of the wastewater treatment method will be described. Since the wastewater treatment method has a gasification hydrogen gas generation step (hydrogen chloride gas generation region Z1) in which the hydrogen gas 3 is reacted with the gas gas 5 at the time of electrolysis by the electrolysis mechanism 1 to generate the vaporized hydrogen gas 6, the hydrogen gas 3 and the gas gas 5 are The reaction produces a hydrogenated gas gas 6. Here, since the reaction heat generation reaction of the following formula occurs when the vaporized hydrogen gas 6 is generated, the reaction heat can be utilized as heat energy to utilize the energy. 1/2C12 (gas) + 1/2 Η 2 (gas) - HC: 1 (gas) + 92.3 kJ / mol, because of the gasification hydrogen gas dissolution step (hydrogenation of hydrogen) for dissolving the aforementioned hydrogen chloride gas 6 in the drainage Since the gas is dissolved in the zone Z2), the gas ions and hydrogen ions after the electrolysis of the hydrogen chloride gas 6 in the drain 7 can be incorporated in the water. Then, since the drain 7 in which the hydrogen chloride gas 6 is dissolved is sent to the electrolysis mechanism, the drain 7 containing chlorine ions is electrolyzed by the electrolysis mechanism 1, and the gas (Cl2) 13 201242908 is generated on the anode side 4. Here, the gas (Cl2) is volatilized by the drain 7 to become the gas 3, or reacts with water to form a sub-gas (HOC1). Ci2 + H20 HC1 + HOC1 By the secondary gas, the contaminated components (organic components, etc.) in the drainage 7 are purified by oxidation and decomposition. Further, the drainage is decomposed and purified by the direct oxidation of the anode electrode 16. Here, as in the above chemical reaction formula of gas and water, the gas (cl2) in the wastewater reacts with water to form a sub-gas acid (HOC1) and hydrochloric acid (HC1), and by increasing the salt 1 pH tends to be acidic. Therefore, due to the decrease, it becomes a sub-gas acid (shame (3) becomes gas (CD is easily volatized by drainage). (Embodiment 5) In the electrolysis mechanism, the electrolysis mechanism 1 may have a diaphragm method or a diaphragm-free method. As shown in Fig. 3, the wastewater treatment method according to the present embodiment includes hydrogen gas 3 generated by the cylindrical cathode electrode 16 and gas generated by the cylindrical anode electrode 5 when electrolyzed by the diaphragmless electrolysis mechanism 1 a step of generating a vaporized hydrogen gas (not shown) by reacting to generate a vaporized hydrogen gas (not shown); and a step of dissolving the vaporized hydrogen gas in which the vaporized nitrogen gas is dissolved in the drain 7 (independently -Step) The diaphragmless electrolysis mechanism 1 circulates by introducing water from the inside of the pump p. The diaphragmless electrolysis mechanism 1 is provided with a cylindrical anode electrode 17 inside the cylindrical cathode electrode 16. Further, volatilization is performed above the electrolysis mechanism i The hydrogen gas (the specific gravity to the air is 0·07) is collected by the piping on the upper side, and the gas 5 (the specific gravity to the air is 2 49) is separately collected by the piping of the lower side by the specific gravity. Then, the gas 5 is blown. Into the row containing sodium hydroxide (Na〇H) Then, a secondary gas l (HOCl) is generated. Then, the gas is volatilized from the drainage 7 when the gas is generated. 201242908 On the other hand, the hydrogen gas 3 is temporarily accumulated in the hydrogen storage region Z4 by the pump P, and the hydrogen chloride is made At the time of gas generation, hydrogen gas is supplied from the storage region Z4. Then, if necessary, the gases are combined and started to react with each other and changed to a vaporized hydrogen gas (not shown). The reaction of chlorine gas 5 generates a heat exothermic hydrogenated gas, heats the water to generate steam, and uses the vapor as energy (for example, power generation). Then, the hydrogen sulfide gas is dissolved in the drain 7 and sent to the diaphragmless electrolysis mechanism. Next, the state of use of the wastewater treatment method will be described. The wastewater treatment method has a gasification hydrogen gas generation step of generating a gasification hydrogen gas by reacting hydrogen gas 3 with chlorine gas 5 which is electrolyzed by the electrolysis mechanism 1. In another step), the hydrogen gas 3 reacts with the gas gas 5 to generate hydrogen chloride gas. Further, since hydrogen chloride gas is generated, a large reaction heat is generated as shown in the following formula, so Heat is generated as heat energy to utilize energy. 1/2C12 (gas) + 1/2 Η 2 (gas) - > HCl (gas) + 92.3 kJ / mol, because it has a gas for dissolving the aforementioned hydrogen sulfide gas in the drainage. The hydrogen gas gas dissolving step (another independent step), so that chlorine ions and hydrogen ions after electrolysis of the vaporized hydrogen gas in the drain 7 can be incorporated in the water. Further, since the hydrogenated gas 6 is dissolved 7 is sent to the electrolysis mechanism 1, so that the drainage 7 containing the gas ions is electrolyzed by the electrolysis mechanism 1, and chlorine (Cl2) is generated on the anode side. Here, the gas (Cl2) is volatilized from the drainage 7 to become chlorine. 3, or react with water to produce hypochlorous acid (HOC1).

Cl2 + H20 — HC1 + HOC1 With this gas acid, the polluting components (organic components, etc.) in the drain 7 will be purified by the oxidation of 15 201242908. Further, the drainage is decomposed and purified by the direct oxidation of the anode electrode 16. Here, as in the above chemical reaction formula of gas and water, the gas (Cl2) in the wastewater reacts with water to form a sub-gas acid (HOC1) and hydrochloric acid (HC1), and by increasing the aforementioned hydrochloric acid, the pH tends to be acidic. Therefore, since the pH is lowered, it becomes an environment in which the sub-gas acid (HOC1) becomes gas (Cl2) and is easily volatilized by the drainage.
