A large amount can be held in the tank. Because this material performs automatic gas lift agitation in the tank, it moves in a staggered manner up, down, left, and right, so it is closer to a fluidized bed rather than a fixed bed in that aspect, eliminating the possibility of clogging. ing. In addition, in the case of a fluidized bed, the adhered biofilm must always be kept relatively thin by keeping the fluidized state in good condition.However, the generation of surplus biofilm is controlled by controlling the gas pressure, gas amount and stirring frequency by automatic gas lift stirring. Because it is controlled, optimization can be achieved, and anaerobic treatment of low, medium and high concentration organic industrial wastewater and household wastewater can be performed with high efficiency.

性度をさらに高める機能を有している。In addition, this automatic gas lift stirrer can change the amount of gas used for stirring, the gas pressure, the stirring intensity, and the number of times of stirring variously by changing the position of the sensor and increasing or decreasing the amount of water injected into the water tank and the stirring tower. , And can be operated under optimum conditions according to the amount of gas generated in the processing tank.
In addition, if the amount of gas generated increases in accordance with the activity of methane bacteria, the frequency of gas lift stirring can be increased, and the methane bacteria have the function of further increasing the activity.

量もまた最大を維持することができる。If the intensity (gas amount and gas pressure) and frequency of the stirring exceed a certain peak, the separation of the biofilm formed on the material surface may increase and the treatment efficiency may decrease. If it exceeds, the amount of generated gas will decrease immediately, so the number of agitation will be reduced accordingly, suppressing peeling and continuously maintaining the maximum gas generation by stirring the gas amount and gas pressure under the always set conditions The automatic control is performed so that the activity of methane bacteria in the treatment tank is maintained at the maximum under the set conditions, and the amount of gas generated can also be maintained at the maximum.

Anaerobic treatment of low, medium and high concentration organic industrial wastewater and household wastewater. In other words, it is possible to treat only wastewater from toilets with relatively low concentrations of organic substances alone, to treat food waste with relatively high concentrations or kitchen wastewater treated with disposers, and to combine some or all of them. In addition, the processing efficiency can be shortened to about one day from the conventional 20 days to 40 days. In addition, adaptation and adaptation of methane bacteria are easy, and problems of clogging and washout are eliminated. Therefore, it was possible to provide a treatment apparatus capable of performing anaerobic treatment with high efficiency by a simple operation regardless of the concentration of organic matter to be treated, such as domestic wastewater, livestock, and factory wastewater, and the type and size of the organic matter.

日で同様の処理効果を得ることが出来る。As described above, the processing tank according to the present invention has a vertical meandering flow,
Both types of vertical and meandering flow and upstream and downstream use minimize the short circuit and unnecessary circulation or detour of the fluid to be treated in the given space of each treatment tank, and use the entire process from inflow to discharge By making the treatment process as long as possible, the treatment efficiency is naturally increased per unit hydraulic retention time. It is said that a single tank type processing tank usually has a slow reaction speed and requires 20 to 40 days. However, a horizontal meandering flow type processing tank forms five chambers with four partitions and operates in a horizontal meandering flow. If you do, put about a quarter of 5 to 10
The same processing effect can be obtained in a day.

る。The jet port 16 of the processing tank is connected to the stirring tower 13 and the gas tank 14 via three electric valves 18, 19, 20 for automatic control of the automatic gas lift stirring device. As described above, the stirring tower 13 is mounted on the water tank 11 having a capacity of 2 m 3 and containing the gas storage chamber 12 of 1 m 3 having an open bottom. The volume difference between the water tank 11 and the gas storage chamber 12 is also 1 m 3 . Further, the inner product of the height of the cylinder from the position L 1 of the bottom of the stirring tower 13 to above the L 2 also becomes 1 m 3.

プを通ってガス溜室12に至る。When water (preferably antifreeze) is injected 2 m 3 from the top of the stirring tower 13, the water fills the gas storage chamber 12 and the water tank 11 because the bottom of the gas storage chamber 12 is open. position
Level until the horizontal line L 1 rises. When methane gas is generated from the processing tank 10, the gas rises and is ejected from the ejection port 16. Of the three motorized valves 18, 19, 20, 18 and 19 are closed
If only 20 is opened, the ejected gas passes through 20 and reaches the gas reservoir 12 through the pipe.

Methane gas is generated from the treatment tank 10 without interruption, and the volume and pressure of the methane gas increase in the gas storage chamber 12, so that the water in the gas storage chamber 12 gradually rises in the stirring tower 13. When rising water level reaches the two points L, since the water level in the transparent pipe 21 is also raised to the same position, sensor 22 is set to the position issues a command for later senses the liquid level. On the other hand, when the water level reaches the position L 2, is in the gas reservoir chamber 12 is filled methane 1 m 3 is the gauge pressure, It is.

ンクに流入しない。Meanwhile, sensor 23 is out command to the moment of sensing the water level of one point L, the electric valve 20 is closed, 18 and 19 are opened. When 19 is opened, the methane gas in the fermenter with a gauge pressure of 0.28 atm flows through 19 into the gas tank 14 to lower the pressure. Stirring gas whereas 18 from a number of small holes for ejecting pipe 17 provided in the processing tank bottom is guided in through pipe 1 m 3 of gas in the gas tank reservoir 12 gauge pressure 0.28 atm 18 because in the open Squirt as. The jetted gas is swirled up and down, back and forth, and left and right between the materials that are growing in the tank and filling the inside of the tank. Via gas tank
Flow into 14. The water depth at the bottom of the processing tank acts as pressure on the inflow of the stirring gas. If the water depth is 140 cm, the gauge pressure becomes 0.14 atm, which is higher than the maximum gauge pressure of the gas tank of 0.13 atm, and the stirring gas does not flow into the gas tank any more.

0.5m 3 is used for stirring, and the remaining 0.5m 3 is stored in the gas chamber 12.
It remains at 0.14 gauge pressure.

段階に入る。After the end of stirring, the electric valve 20 is opened, 18, 19
Are closed, the methane gas generated from the processing tank flows into the gas storage chamber 12 again to raise the water level of the stirring tower 13. Unless the amount of gas generated in the treatment tank fluctuates, about 1/2 next time
Water level by the time the stirring is performed reaches the two points L. When the gas in the gas reservoir 12 enters the treatment tank via the electric valve 18 and stirs and flows into the gas tank 14 via 19, the gas reservoir 12,
Since the pressure in the treatment tank 10 is in an equilibrium state, immediately thereafter, when the electric valve 20 is opened and the electric valves 18 and 19 are returned to the closed state, the gas is accumulated again in the gas storage chamber 12 and the next stirring is performed. Enter the preparation stage.

もし、人為的に攪拌回数を減少させる場合は、平衡状

Then keeping the water level L 2 put 3m 3, and lowered the sensor to 210cm high L 3-point than L 2. Water level does not need to account for the water depth of the treatment tank has exceeded a gauge 0.14 by water depth 140cm the longer the processing tank that is in two points L. If there 'stirring the water level reaches the L 3 points, methane gas 1 m 3 of a gauge pressure of 0.49 to 0.21 are used all stirring.

対に感知器を引き下げればガス圧は低下し、ガス量も減
少し、攪拌の強度は弱くなるが、攪拌回数は増加する。In general, the amount of water is kept constant except when the gas in the gas reservoir 12 is blown into the atmosphere from the stirring tower without being used for agitation before sensing due to lack of water or the arrangement of the sensor is too high. When the pressure is raised, the gas pressure and gas amount used for stirring increase, and the intensity of stirring increases, but the number of times of stirring decreases. Conversely, when the sensor is lowered, the gas pressure decreases, the gas amount also decreases, and the intensity of stirring decreases, but the number of times of stirring increases.

量に応じて最適条件下で操作することができる。Next, increase the amount of water by keeping the position of the sensor constant,
Although the maximum gas pressure used for stirring is constant, the amount of gas decreases, the intensity of stirring increases on average, and the number of times of stirring increases.
Conversely, when the amount of water is reduced, the maximum gas pressure used for stirring is the same, but the amount of gas increases, the intensity of stirring is weak on average, and the number of times of stirring is reduced. By changing the position of the sensor and increasing or decreasing the amount of water injected into the water tank and the stirring tower, the amount and pressure of gas used for stirring, the stirring intensity and the number of times of stirring can be varied, and the amount of gas generated in the processing tank Can be operated under optimum conditions.

Contact with water inside, and at the time of stirring, gas reservoir 12 and stirring tower
After being mixed violently with water in 13, it reaches the bottom 17 of the treatment tank 10, and then becomes large and small bubbles in the treatment tank and separates and floats between the materials in the water to be treated. After passing through 19, it flows into the gas tank 14.

も都市ガスコンロの流用に限られている。Generally speaking, the component composition of the gas generated from the conventional methane gas generator is methane gas 60% to 70%, carbon dioxide gas 40% to 30%, and contains a slight amount of hydrogen sulfide depending on the type of organic projection. There are cases. Therefore, although it can be used as a fuel, it has a slight odor during combustion, and its combustion tools are limited to the use of city gas stoves.

率をあげることが可能になっている。Of course, the methane concentration also changes due to the variation in the type and concentration of the input organic matter, but it is possible to increase the methane concentration by about 20% (eliminate the carbon dioxide gas by that much) compared to other general generators. Therefore, the odor of methane gas generated from the present apparatus at the time of combustion is completely eliminated, and the calorie is much higher than that of city gas, so that the combustion efficiency can be improved close to that of natural gas.

Since the tip 30 of the pipe 28 is diversified at the bottom of the apparatus 29, the gas rises as a number of bubbles, and the pipe 31
And enters the gas flow chamber through the closed electric valve 20.

効用がある。Therefore, by installing the apparatus 29, lime water washing is added twice, once before and after the automatic gas lift stirring. If lime water is used as the water in the water tank 12 and the gas tank 14 of the stirrer, the methane concentration is further increased, the methane concentration becomes closer to natural gas, and the experimental results also remove hydrogen sulfide. The precipitated calcium carbonate CaCo 3 can be regenerated and reused, but if mixed with fertilizer, it has the effect of increasing the fertilizer effect.

各室内に一杯に林立状ないし並列横臥状に設置する。4. Material Each chamber of the treatment tank is filled with a material 24 as shown in FIG. This material is composed of a core material 25 and a number of thin synthetic resin tapes 26 radially extending therearound. For example, a tape 26 made of a synthetic resin thin wide film is cut to a fixed length of 30 to 60 cm, aligned at the same density and juxtaposed, and a stainless steel core material at the center.
It is formed by twisting this core material 25 by passing it up and down, and the procedure for making it is the same as a rod-shaped brush, but its shape is as if it was a car-shaped rod made of long ostrich tail blades Similar to Hataki. This material 24 is placed in each room in a forest-like state or a side-by-side state.

に操作も容易で故障が少なく処理効果も大きい。As an installation method, for example, a method can be adopted in which the base material 25 is attached to a frame having upper and lower ends or left and right ends framed, and the frame is installed in each room. As for the degree of the stand or the side-by-side state, a material having a density such that each material 24 spreads the tape-like body 26 horizontally in the processing liquid and touches each other is generally easy to operate, has less trouble, and has a large processing effect.

害物や有機物を溶出することがない。As a synthetic resin used as a raw material of the material, a polypropylene resin is optimal, but it is not necessary to limit to it, and any kind may be used as long as it has the same properties and performance. Polypropylene is inexpensive and can be supplied stably, and its specific gravity is as light as 0.9.The tape-shaped body made of its wide film spreads straight to the tip horizontally during processing, and the material is extremely mechanical. It is tough, does not deteriorate in water, and contains no plasticizers, so that no harmful substances or organic substances are eluted in water.

れはない。Further, since the molecules are correctly arranged in a vertical direction, the tape-shaped body is not broken and shortened. If a strong shock or continuous vibration is applied for a long period of time, the fiber will be split vertically and become a thread, further increasing the surface area. Therefore,
The more it is used, the larger the contact surface with the cells and the greater the amount of retained sludge, so that the efficiency of methane fermentation is improved. Since the stainless steel core material, which is the core of the material, is submerged in the liquid of the organic substance to be treated, there is no possibility of causing metal corrosion.

欠である。The purpose of filling the material and carrier in the treatment tank is to fix the microbial membrane of the anaerobic bacteria to the material and carrier so that the anaerobic bacteria participating in the reaction can be retained in the tank as much as possible. Both the fixed bed type and the fluidized bed type are the same. In the case of fixed beds, there is generally a high possibility of clogging, and countermeasures are indispensable.

本攪拌方式がその要求を満足させている。Although the materials used in the present invention fall into the category of fixed beds from a classification point of view, it is argued that the possibility of clogging is eliminated in view of their shape and performance and also because of the aforementioned automatic gas lift stirring. Not together. In the case of this material, the adhered microbial membrane on the tape-like body that protrudes horizontally and straight in the tank is swung up and down, right and left, and back and forth by methane gas ejected from many holes on the bottom of the fermentation tank. In view of this, it can be said that it has a fluidized bed rather than a fixed bed. In the case of a fluidized bed, the fluidized state must be maintained well to keep the attached biofilm relatively thin at all times. In order to maintain such a state, it is necessary to fluidize the inside of the tank by inflow and stirring of an organic substance, and the material and the stirring method satisfy the demand.

のような特殊な材を用い、また自動ガスリフト攪拌に
よるガス圧、ガス量及び攪拌頻度の制御で余剰生物膜の
発生を抑制して最適化を計ることができるからである。It is generally said that the fluidized bed method has a feature that can be applied to low-concentration wastewater treatment.However, this method enables not only high-concentration and medium-concentration treatment but also low-concentration treatment. This is because the use of such a special material and the control of the gas pressure, the gas amount, and the stirring frequency by the automatic gas lift stirring can suppress the generation of the surplus biofilm and achieve the optimization.

また、流動床式の欠点として挙げられている槽内の流

利点を有している。In addition, as for the increase in power cost for fluidization in the tank, which is mentioned as a disadvantage of the fluidized bed type, the electric valve for control is used because automatic gas lift stirring uses the amount of gas and gas pressure generated naturally. It has the advantage that no power other than the power to move is required.

However, if the biofilm undergoes a shear stress or the like of the fluid during the process of swaying in the liquid and the biofilm largely separates and flows out, the treatment efficiency is significantly reduced.

ある。Conversely, when the biofilm is immobilized and becomes enlarged, there is no fluid flow in the biofilm, and the substrate permeates from the surface to the inside by molecular diffusion, and when the substrate is consumed by microorganisms in the diffusion process, It is said that the processing efficiency is reduced due to the distribution of the substrate concentration in the biofilm. The rate of increase in biofilm formation is slow and large, and it takes a long time to recover if it is separated and discharged.Therefore, it is necessary to keep the cell concentration in the tank constant for a long period of time, keeping the separation to a degree that does not cause excess biofilm. There is a need to.

では特定の高濃度有機物の処理に限られている。Conventionally, the method of controlling the film thickness is based on mechanical agitation or a pump, but it does not fall outside the range of high skill and experience. Microbiological research on anaerobic treatment has made great progress in recent years, and enormous information materials have been reported.However, methods for quantifying various bacteria that are responsible for anaerobic treatment have not been found and are high. Efficient methane fermentation methods are not designed based on the metabolic characteristics or physiological characteristics of acid-producing bacteria or methanogens, and such operations are not performed. However, the anaerobic bacteria participating in the reaction are kept in the tank as much as possible, and as a result, at present, the treatment is limited to the treatment of specific high-concentration organic substances.

It is a finding that the activity of methane bacteria is proportional to the amount of methane gas generated. (The amount of gas generated temporarily increases immediately after overload,
Excludes exceptions such as an increase in the ratio of carbon dioxide, followed by a significant decrease in the activity of methane bacteria and a decrease in gas volume. ) A certain amount of methane gas generated at a certain activity of methane bacteria is
If the microorganisms are used for stirring at a certain gas pressure and frequency and the frequency of collisions between the microorganisms and the organic substance as the substrate further increases, the amount of gas generated further increases and the same amount The frequency of gas lift agitation of the pressure increases, and the methane bacteria further increases the activity, the amount of gas generation further increases, and the number of times of shaking increases.

に自動的に制御されている。However, if the intensity (gas amount and gas pressure) or frequency of stirring exceeds the limit, the detachment of the biofilm becomes large and the amount of gas generation decreases. Even if the operation is changed after the fall, it is already late, and it takes a long time to fix the biofilm. In this automatic gas lift agitation, the amount of generated gas is reduced immediately if the peak is exceeded, so the number of agitation is reduced accordingly, and the maximum amount of agitation at the set amount of gas and gas pressure under the set conditions is suppressed to reduce peeling. It is automatically controlled to maintain gas generation continuously.

最も高い操作となるわけである。Under such a condition, the activity of methane bacteria in the treatment tank is maintained at the highest level, and the amount of generated gas is also maintained at the maximum. In operation, the maximum amount of gas (gas amount x gas amount) is changed by changing the amount of water injected into the water tank and stirring tower and the position of the sensor, taking into account the nature, concentration and amount of the organic matter to be treated.
Pursuit of (gas pressure x number of stirrings) is the highest operation in terms of the processing efficiency of the organic matter charged in the tank at that time.
