Description

IONIZED GAS AIDED CIRCULATION NON-DISCHARGE SYSTEM AND METHOD FOR TREATING EXCREMENTS WASTEWATER}

The present invention relates to a circulating non-discharge manure wastewater treatment system and method using ionization gas for treating the wastewater as a heavy water that can be recycled using ionized gas.

As is well known, manure waste water discharged from a flush toilet and the like is mainly treated by a septic tank. Septic tanks are developed in many different structures, and are generally composed of decaying tanks, oxidizing tanks, and disinfection tanks. The decay tank reduces the volume of manure wastewater by stabilizing the organic waste with inorganic matter by liquefying and gasifying the incoming manure wastewater by anaerobic digestion for about 48 hours. The septic tank is supplied to the oxidizing tank and oxidized by contact with air. The sterilizing tank sterilizes waterborne pathogens and parasite eggs by injecting chlorine solution and discharges them into public sewers or natural waters.

In such a septic tank, sludge of a rot tank is periodically collected and treated separately in a sewage treatment plant or a manure wastewater treatment plant. However, when the sludge exceeds the capacity of the decay tank, the wastewater is discharged as it is to public sewers or natural waters, increasing water pollution, and causing infectious diseases due to exposure of waterborne pathogens. On the other hand, the use of tap water in tap water in the flush toilet not only causes waste of water, but the use of excess tap water is an economic and social burden. In particular, water pollution causes the depletion of industrial and agricultural water and drinking water, which is a serious social problem. Therefore, in recent years, technologies for treating the tap water, which has been used once, can be recycled into domestic water and industrial water to reduce the consumption of water and reduce the generation of sewage, and to maintain water quality and supply stable water.

However, manure wastewater is known to be very difficult to treat due to various factors such as organic matter concentrations, nutrients such as nitrogen (Nitrogen) and phosphorus (Phosphorus), high molecular weight, odor and color. Conventional rotary disc method, activated sludge method, and catalytic oxidation method using microorganisms for the treatment of such wastewater are prolonged treatment time, excessive facility area, increased treatment cost, large amount of sludge, impossibility of color removal and odor generation. It was very inadequate for application to the treatment of heavy waters with such problems.

On the other hand, in conventional toilets and simple toilets, manure wastewater is fermented and decomposed by wood chips in which microorganisms are cultured for no discharge of manure wastewater, but the control factors such as temperature, moisture, and time required for the growth of microorganisms There is a problem that is very difficult to maintain, and there are many problems such as the death and growth of microorganisms due to the change of driver factors. In addition, there is an unsanitary problem that cannot be sterilized such as waterborne pathogens and parasites, and there is a problem that a separate sterilization facility should be installed for sterilization treatment.

Referring back to FIG. 1, a second decomposition tank 160 is disposed downstream of the fermentation decomposition tank 140 to store the effluent of the unit process that has passed through the fermentation decomposition tank 140. The water collecting tank 144 and the second decomposition tank 160 are connected by the fifth pump 148. A fourth aeration device 170 is installed at the bottom of the second decomposition tank 160 to aeration the ionization gas injected from the first air injection device 60 into the second decomposition tank 160. Like the first aeration device 70, the plurality of nozzles 170 are provided with a plurality of nozzles 172 so that the entirety of the second decomposition tank 160 can be aerated evenly. The second decomposition tank 160 and the manure wastewater generating source 10 are connected by a sixth pump 162, whereby the system of the present invention can be configured in a circulating manner.

Figure 5 is a flow chart for explaining the wastewater treatment method according to the present invention. Looking at the treatment method of the high concentration organic wastewater according to the present invention with reference to Figure 1 and 5, first, the manure wastewater generated from the manure wastewater source 10, such as flush toilet, conventional toilet, simple toilet flow rate equalization tank (20) (S200). At this time, the flow equalization tank 20 stores a sufficient amount of manure waste water to be able to constantly supply the required amount of manure waste water required in the subsequent process so that the operation of the system can be efficiently performed. When the manure waste water collected in the flow balancing tank 20 reaches a constant level, the waste water of the flow balancing tank 20 is supplied to the grinder 30 by the operation of the first pump 24, so that the particles and the solids of the manure waste water. To finely grind (S202). By finely pulverizing the particles and solids of the manure waste by the operation of the crusher 30 in the subsequent process the contact area of the ionizing gas and the microorganism can be increased to greatly improve the treatment efficiency. The manure waste water pulverized by the operation of the crusher 30 is supplied to the first decomposition tank 40 and stored (S204). At this time, the first decomposition tank 40 stores the ground manure waste water of the unit process.

Next, when the manure wastewater of the unit process is stored in the first decomposition tank 40, the ionization gas is generated by the operation of the ionization gas generator 50 (S206). Ionization gas is injected into the second decomposition tank 110 together with air by the operation of the first air injection device 60, the first aeration device 70 of the first air injection device 60 is air and ionization gas To aeration in the wastewater of the second decomposition tank 110 (S208). At this time, the ionizing gas is uniformly aerated in the first decomposition tank 40 through the nozzle 72 of the first aeration device 70.

The ionized gas reacts with the air injected by the first air injection device 60 to generate a large amount of radicals, and simultaneously decomposes and separates organic substances while reacting with the manure wastewater. That is, the ionized gas is decomposed and separated by reacting with organic matter having a simple bonding structure in the wastewater. Radicals react with water molecules to produce a large amount of oxides such as OH radicals, ozone, and hydrogen peroxide, which have strong oxidative power. do. At this time, the ring-linked material of the polymer, such as the polymer compound contained in the manure waste water is decomposed and separated to change the material of the simple molecular structure. In particular, OH radicals react with all organics at a very high rate to effectively decompose and separate the organics. As described above, since the hardly decomposable substances, such as organic matter and chromaticity, contained in the wastewater can be decomposed and separated by strong oxidizing power and energy such as ionization gas, radicals, and ozone, the treatment efficiency of the wastewater can be greatly improved. This can increase the decomposition efficiency of organic matter by digestion of microorganisms in subsequent biological treatments. Organic matters vary depending on the characteristics of manure wastewater, but are finally converted to CO ₂ and H ₂ O, and excess radicals are naturally decomposed and extinguished.

Subsequently, the reaction water having passed through the first decomposition tank 40 is supplied to the degassing tank 80 by the operation of the second pump 42, and the second air injection device 90 is supplied to the reaction water of the degassing tank 80. The air injected from the a) is aerated by the second aeration device 100 to degas ionized gas, odor components, etc. dissolved in the reaction water into the atmosphere (S210). In this way, by completely degassing the ionizing gas, odor component, etc. in the reaction water in the degassing tank 80, it is possible to effectively eliminate the killing and growth of microorganisms in the subsequent biological treatment.

2 and 5, the outflow water discharged after the degassing in the degassing tank 80 is completed is supplied to the contact oxidation tank 110 by the operation of the third pump 82, and to the contact oxidation tank 110. The organic matter in the supplied effluent is decomposed by primary biological treatment (S212). At this time, the microorganisms attached to and grown on the porous ceramic carrier 120 of the contact oxidation tank 110 decomposes organic matter into CO ₂ , H ₂ O and inorganic matter. In addition, the third aeration device 130 connected to the second air injection device 90 aerators the air from the second air injection device 90 to the contact oxidation tank 110 to activate digestion and growth of microorganisms. Since 60% or more of organic matters may be firstly removed by the first biological treatment of the catalytic oxidation tank 110, the load may be reduced in the downstream pyrolysis tank 110 to increase the treatment efficiency of the organic matter.

1, 4 and 5, the effluent water after the first biological treatment of the contact oxidation tank 110 is supplied to the watering device 146 by the operation of the fourth pump 116, the watering device 146 ) Sprinkles and supplies the effluent to the digestion tank 112 of the fermentation digestion tank 110, and the organic matter remaining in the effluent supplied to the digestion tank 112 of the fermentation digestion tank 110 is decomposed by secondary biological treatment. (S214). Organic matter in the effluent water, which is sprayed on the upper part of the decomposition tank 112 and flows to the bottom through the watering device 146, is adsorbed to the ceramic carrier 150, and the organic matter is attached to the ceramic carrier 150 to grow by CO _{2. ,} it is decomposed into H ₂ O and a small amount of inorganic substance. At this time, since the outside air flows into the decomposition tank 112 through the vent hole 112a of the decomposition tank 112, in the ceramic carrier 150 close to the inner surface of the decomposition tank 112, aerobic digestion by aerobic microorganisms Is done. In the center of the digestion tank 112, oxygen in the air introduced through the vent hole 112a is consumed by the digestion of the aerobic microorganisms, so that anaerobic digestion by the anaerobic or arbitrary microorganisms is performed.

As described above, aerobic digestion and anaerobic digestion are performed in the digestion tank 112 of the fermentation digestion tank 110 to efficiently remove organic matter and color of various properties, and increase the activation of microorganisms to improve treatment efficiency. . On the other hand, in the position close to the center of the ceramic carriers 120 and 150 provided in each of the contact oxidation tank 110 and the fermentation digestion tank 140, sludge of the old age by protozoa and metazoa Since the self-extinguishment from the sludge is continuously attached to a certain thickness, it is effectively prevented from killing microorganisms, inhibiting growth and dropping of the biofilm from the ceramic carriers 120 and 150. This enables the activation of microorganisms and stable biological treatment, and in particular, the high concentration of manure wastewater can be treated quickly and accurately.

Next, the effluent collected in the collection tank 114 of the fermentation cracking tank 110 is supplied to the second cracking tank 160 by the operation of the fourth pump 116 (S216). When the manure wastewater of the unit process is stored in the second decomposition tank 160, the first air injection device 50 supplies the ionized gas generated by the operation of the ionization gas generator 50 as in the first decomposition tank 40. Injected into the fourth aerator 170 by aeration and aerated (S218). The fourth aeration device 170 aeration of the ionization gas in the second decomposition tank 160 to decompose and separate organic matter, color and odor components remaining in the effluent, as well as to generate a large amount of oxide material to generate water in the effluent. Sterilize tough pathogens, parasites, etc. Lastly, the deuterium having passed through the second decomposition tank 160 is supplied to the manure wastewater source 10 by the operation of the sixth pump 162 and recycled (S220). Therefore, it is possible to prevent water pollution with no discharge of manure waste water, as well as to effectively reduce the amount of water used to enable economical and efficient use of water resources.

The present invention looks at the efficiency of the circulating non-discharge manure wastewater treatment system using the ionization gas of the present invention and the treatment efficiency of the manure wastewater by the method.
