Detailed Description of the Invention

The multipurpose combined septic tank of nitrogen / phosphorus removal according to the present invention separates and introduces high concentration manure into the first digestive chamber 15 for high-speed aerobic digestion, which is suitable for high speed decomposition of high concentration organic wastewater. In this process, undecomposed residual material and low concentration general sewage are mixed in the second digestion chamber 20 to perform a second high temperature aerobic digestion to increase treatment speed while maximizing treatment efficiency.

In the case of the second digestive chamber, TS (TOTAL SOLID) is lowered, so that the high temperature aerobic digestion rate may be lowered. Therefore, it is preferable to add an appropriate amount of bio media (BIO-MEDIA). More preferred is a fluidized bed with few obstacles.

The general sewage flowing into the flow control room 99 is automatically introduced into the second digester 20 when the water level of the flow control room 99 reaches the weir level of the sedimentation separation chamber. Considering the temporary discharge during the afternoon generation time, the wastewater flow in each chamber may be accelerated during the generation time, and thus the treatment efficiency and sedimentation efficiency may be lowered. Therefore, when the water level of the flow control room 99 reaches the upper limit, the water level detecting line 88H is detected. The water level automatic regulator 87 sends an operation signal to the timer 85, and the timer 85 blocks the electronic valve 75 at a predetermined time period (for example, about 1 minute at 30 minute intervals) to allow the underwater explosion apparatus 40 to operate. The suction force of the underwater aeration apparatus 40 acts on the sewage suction Y-tube 38 by blocking the air suction Y-shaped tube 78 side of the suction pipe of the suction pipe, and the sewage of the flow rate adjusting chamber 99 is uniformly extinguished by a predetermined amount every predetermined time. It is introduced into the chamber 20. Therefore, it is possible to minimize load fluctuations in temperature, microorganisms, and organic matter in the second digestion chamber 20, to maintain stable separation efficiency of the precipitation separation chamber 23, and to remove nitrogen and phosphorus from the aquatic plant tank 28. Maintains a low flow rate for In addition, the flow rate adjusting room 99 operates the timer 85 to be emptied within the next occurrence time of the sewage, and when the sewage reaches the lower limit, the water level regulator 87 stops the timer 85 by detecting the water level detecting line 88L. The solenoid valve 75 remains open to allow air to pass through, so that the sewage below the level detection line 88L of the flow control chamber 99 is locked to the residual sewage in a predetermined depth. In this state, the feed stops and the flow rate control chamber above the water level detection line 88L becomes empty and can serve as a buffer for the next occurrence time.

In the present invention, the sewage is designed to be transported by the underwater aeration apparatus 40 of the second fire-extinguishing chamber 20 without using a separate transfer pump, thereby reducing energy costs and facility costs. Meanwhile, the oxidative heat energy of the high temperature microorganisms generated in the first and second digestion chambers 15 and 20 is partially recovered and settled to the heat exchange transfer pipe 36 which transfers the wastewater during the transfer to the sedimentation separation chamber 23. It gradually lowers for 3 to 5 hours in the separation chamber 23 to maintain 25 to 35 ° C. in the aquatic plant tank 28 to provide optimum temperature conditions for the growth of aquatic plants, and lower the flow control chamber 99. In the heat exchange transfer pipe 31 which rotates until it is conducted again the heat remaining in the sewage. In addition, some of the energy of the gas of the oxidative heat energy of the high temperature microorganisms in the first and second digestion chambers 15 and 20 is re-absorbed into the cyclones 59 and 79 which are internal gas recirculation systems of the respective chambers 15 and 20. It is mutually transferred to the wastewater, and part of the heat passing through the exhaust heat discharge pipe 65 through each of the cyclone exhaust pipes 61 and 81 is heat-exchanged with the outside air in the exhaust heat recovery pipe unit 50, and then the first and second fire extinguishing chambers ( Through each of the external air connecting pipes (53, 70) of the 15, 20, the external air inlet pipes (54, 71) in each of the digestion chambers are introduced into the exhaust chamber (15, 20) is finally recovered into the interior, exhaust heat Instead of losing heat energy, each exhaust gas passing through the discharge pipe 65 reduces the amount of oxygen and increases the concentration of carbon dioxide (CO2) during the metabolism of aerobic microorganisms in each digestion chamber.

This gas becomes a carbon dioxide gas source for the carbon assimilation of the aquatic plants 29 in the aquatic plant tank 28, and is supplied to the aquatic plant tank 28 through the carbon dioxide gas supply pipe 67. ) And the air from which carbon dioxide is consumed and oxygen is selectively supplied to the first and second digestive chambers 15 and 20 via the exhaust heat recovery pipe unit 50 through the plant oxygen suction pipe 51a, or the exhaust conveying pipe. Inflow to the upper portion of the flow rate adjusting chamber 99 through 68 is discharged to the outside air through the final exhaust pipe (69).

As described above, the system of the present invention is an artificially reduced system configured to maintain the optimal recycling (RE CYCLE) phenomenon occurring in the natural ecosystem in the minimum space as quickly and effectively as the main technical features. On the other hand, the supply of oxygen required for the first and second fire extinguishing chambers (15, 20), each of the underwater aerators (58, 40) is installed on a horizontal stand of the lower portion of the inside of each fire extinguishing chamber, each of the aerators to cause a centrifugal force The suction pipe is made into a partial vacuum by the impeller, and the intake air is sucked in. The sucked air is mixed with water, and small air bubbles are crushed to make quick contact with the waste water. In addition, the centrifugal force of the impeller and the upward force of the air bubbles rapidly agitate the wastewater in each tank. At this time, the air rising above the water surface obtains the frictional energy of each of the underwater aerators (58, 40) impeller and obtains the energy generated by the high temperature microorganisms while contacting the wastewater, and the temperature rises, but oxygen is sufficiently dissolved by only one contact with the wastewater. Since it has a large amount of oxygen, it does not just exhaust it, but enters the air vent of each cyclone (59,79), which is an internal air recirculation device, and rotates by a guide vane fixed in a constant gradient to defoam bubbles. It is sucked into underwater aerators and re-aerated to increase the utilization of oxygen in the air, effectively preventing the outflow of internal energy. On the other hand, the amount of oxygen in the internal circulating air that is insufficient due to the recirculation aeration of the internal air is the external air control valve (63, 83) according to the load of organic matter flowing into each digestion chamber (15, 20) and the temperature state of each digestion chamber Make appropriate adjustments to make up. In addition, when automating the temperature of each digestion chamber to maintain a constant temperature, the manual control valves 63A and 83A are completely opened, and the automatic solenoid valves 63B and 83B are operated in conjunction with the temperature automatic regulator 108 of each digester. .

In the first and second fire-extinguishing chambers 15 and 20, each of the baffles 16 and 21, which prevents the newly introduced wastewater and the treated water from being transferred to the next chamber, from being mixed, is located far from the original wastewater inflow position. The baffle has a shape structure such that only the lower end of the baffle is blocked, and the treated water which has been gradually transferred from the lower part of the baffle to the upper part of the baffle is separated from the large solids. It is introduced into the upper inlet of and transported to the next treatment chamber. This separation of solids is to maintain a TS or more than a predetermined concentration required for the first digestion chamber 15, to prevent overload of the second digestion chamber 20, and to reduce the inflow of untreated water into the precipitation chamber.

The sludge precipitated and separated from the sedimentation separation chamber 23 is collected in the sludge storage chamber 24 having the same shape inside the lower half moon, and the collected sludge is introduced into the sludge inlet 41 for microbial resupply of the first digestive chamber 15. And the vehicle is driven up to the sludge conveying pipe 42, and the ambient pressure due to the rising water flow at the outlet 43 of the sludge conveying pipe which is located at the ascending stream by the underwater aerator 58 of the first fire-extinguishing chamber 15. The conveyance is made to the 1st fire extinguishing chamber 15 by the fall of. The sludge shutoff valve 44 can be properly adjusted so that the amount of conveyance is not excessive, and the sludge shutoff valve 44 is connected to the sludge handlebar 45 and connected to the sludge valve handle 46 outside the tank. Operation is possible. Since the sludge valve handle 46 conducts heat energy inside the tank, the sludge valve handle 46 is thermally treated by the heat insulating cap 47 having a double structure containing air in the cap. On the other hand, the long-term storage of the lower sludge is connected to the valve and the pipes such as to transfer to the lower portion of the aquatic plant tank 28a, and in contact with the roots of the aquatic plants to continue the decomposition process and to be used as a nutrient source of aquatic plants. The supernatant separated from the sludge in the sedimentation separation chamber (23) is raised and collected in the water channel (26) through the horizontal weir 25, the lower corner of one side of the aquatic plant tank (28) along the treated water connection pipe (27) As it flows in, it moves at a slow speed in the form of diagonal flows over the diagonal corners of the aquatic plant tank 28.

The aquatic plant tank 28 is divided into three tanks, the first aquatic plant tank 28a is an aquatic plant (e.g. a horseweed), and the second and third aquatic plant tanks 28b, 28c are aquatic plants above the water surface. By planting (e.g., Breoxam, duckweed, etc.), horseweed produces oxygen in the water, and Breoxam releases oxygen in the air layer, which again aerobic the treated water and air layer flowing through the aquatic plant tank 28. Will remain in the state. The water temperature of the aquatic plant tank 28 is maintained at a temperature range of 25 ℃ to 35 ℃, which is the most suitable temperature for the growth of Breoxam, etc., so the carbon dioxide is also required as much as the growth rate is strong. As the temperature decreases, growth slows and there is concern about the company. Therefore, the exhaust gas having a high carbon dioxide concentration discharged by the metabolism of microorganisms in each digestion chamber is lowered in the exhaust heat recovery pipe unit 50 so as to enable the supply of a large amount of required carbon dioxide while blocking external air, and then the carbon dioxide gas supply pipe ( 67) into the aquatic plant tank 28. Meanwhile, the air of the aquatic plant tank whose oxygen concentration is increased again by the carbon assimilation of the aquatic plant is selectively supplied to the first and second digestive chambers 15 and 20 through the plant oxygen supply pipe 51a.

Therefore, the multipurpose combined septic tank is preferably installed so that the aquatic plant tank 28 faces south in a sunny location, and the optimum growth temperature and amount of carbon dioxide are secured, so that growth of breoxam horseweed and the like is vigorous and nitrogen. The removal efficiency of wine is improved. When the efficiency is further increased, the lamp 111 is turned on for a predetermined time even at night, or when it is inevitable to install in a location where sunlight is hard to enter, it is preferable to continuously light a predetermined time every day by a timer. The upper cover of the aquatic plant tank 28 can be installed with a double glass having a transparent acrylic or an air layer that can be mined and low thermal conductivity. Breoxam, etc., when the breeding is overcrowded, part of it is often taken out, it is also preferable to use it as a compost raw material such as feed or edible snail, edible snail or livestock snails.

The treated water from which nitrogen and phosphorus are removed from the aquatic plant tank 28 is again discharged through the treated water outlet 32 after delivering residual energy to the sewage of the flow rate control chamber 99 through the heat exchange transfer pipe 31.

Sewage flowed into the flow rate control chamber 99 obtains residual energy from the heat exchange transfer pipe 31 through which the treated water is transferred, and the upper and lower water levels are constant according to the detection depth of the water level detecting line 88 of the automatic water level regulator 87. It is only filled up to the range, there is no reverse flow phenomenon because it does not rise above the weir 25 of the sedimentation separation chamber, and also does not lower below the lower limit, the flow rate adjusting chamber 99 by the underwater explosion apparatus 40 of the second fire chamber 20 Air inflow is not achieved. That is, prevention of air inflow of the flow regulating chamber 99 is possible because the tip of the sewage feed pipe 35 of the flow regulating chamber 99 is bent downward and always locked to the depth of the residual water below the sewage lower limit. The second digestive chamber 20 end portion of the sewage feed pipe 36 has a curved upper portion 36A, and the upper end portion thereof is at the same height as the water level detection upper limit, so that the sewage of the flow rate adjusting chamber 99 is level. It does not flow into the second digestive chamber 20 until the upper limit of detection 88H is reached. However, the amount greater than the amount of filthy water transferred to the effluent suction Y magnetic pipe 38 of the underwater aerator 40 under the control of the timer 85 while the filthy water is filled up to the water level detection upper limit 88H of the flow control chamber 99. When sewage flows in at a time, the sewage is transferred into the second fire chamber 40 by the level difference despite the control of the timer 85, so that the sewage does not overflow to the outside of the tank or flow back into the bath or kitchen.

Even in the case of temporary inflow of large amounts of sewage, the high temperature microorganisms of the first digestive chamber 15 are continuously replenished to the second digestive chamber 20, thereby quickly recovering normalization of the treatment.

Meanwhile, the manure inlet pipe 13 and the sewage inlet pipe 34 each have a T-shaped opening vertically at their ends, so that the gas in the manure conveying pipe 12 and the sewage conveying pipe 33 does not stay. have.

Each manhole of the tank should be about 400 ~ 50mm in diameter. Each manhole cover (105, 107, 109) has a double structure having an air layer, the rubber packing 113 is attached to the outside of the insertion portion and the air injection rubber 112 is mounted on the top of each manhole cover to fit the manhole cover in the manhole and then air injection Injecting air through the rubber 112 causes each manhole cover to expand and compress the manhole to maintain complete airtightness. Each of the pipes and the heat exchange unit 50 exposed to the upper tank is kept warm, but the final exhaust pipe 69 is not kept warm. The inner cylinder 100 of the tank body is made of reinforced plastic (FRP) material having a low thermal conductivity, and about 50 to 100 m / m foamed urethane insulation layer 101 is formed on the outside thereof, and the outer cylinder 102 is heat conductive again. Finished with low strength reinforced plastic (FRP) material. Between the inner cylinder 101 and the outer cylinder 103, a K-type support layer (SUPPORT LUG) made of a reinforced plastic material is formed so that the thermal insulation layer 101 is not compressed.

On the other hand, the material of the inner pipe (65,36) of the heat exchange and the double pipe is preferably a stainless steel pipe, the outer pipe (50,22) of the double pipe is a reinforced plastic (FRP) material or polyvinyl chloride (PVC) material Is installed with pipes. The materials of the other conveying pipes 18, 27, 42, 67, 68, 151, 151a and the exhaust air exhaust pipe 69 are also preferably made of reinforced plastic (FRP) or polyvinyl chloride (PVC). The heat exchange transfer pipe 31 is preferably a stainless steel pipe.

The mother pipes of the pipes (53, 62, 70, 82) and the external air inlet pipe (51) connected to the manhole covers (105, 107) are connected to the flanges (106), which can be easily dismantled, to separate them, and then remove them. Lifting the manhole covers 105 and 107 makes it easy to inspect the inside of the manhole, and the exhaust heat recovery pipe unit 50 can be easily replaced with the complex wastewater treatment system type. When dismantling the manhole cover, the manhole cover can be easily separated by first removing the air from the air inlet 112 above the manhole cover and then lifting it up.

When lifting each underwater aerator 58,40 in the first and second fire extinguishing chambers 15 and 20, the lifting chains 92 and 94 can be lifted. In this case, each air transfer hose 55, 73,77,37 is composed of a flammable high-pressure hose can be lifted without dismantling each connection in water. On the other hand, the multipurpose combined septic tank of the present invention can be processed together with kitchen food waste that can be crushed by a crusher, a juicer and the like. In other words, each object to be treated is first ground by an appropriate machine and then introduced into the first high temperature aerobic digestion chamber through a toilet. In the case of high temperature aerobic digestion, the concentration of total solids (TS) is about 2% (20,000 mg / l) or more. However, in modern houses, urine and toilet are not installed separately, but only toilet is installed. Edo, regardless of age or sex, discharges more than 18 liters of water at a time, and the average concentration of manure has been changed to a level slightly lower than that of the conventionally investigated literature (about 20,000 to 25,000 mg / l of BOD). Therefore, bone types and food wastes other than crabs or shellfish in the kitchen wastes are crushed with a crusher, a juicer, etc., and flowed into the first digestive chamber 15 to provide high-temperature aerobic digestion treatment with manure. It is possible.

In addition, the multipurpose combined septic tank of the present invention, in addition to the purpose of efficiently purifying organic matter, such as manure sewage, food waste, livestock wastewater, etc., at the same time can obtain the energy necessary for cooking, heating, housekeeping, heating greenhouses, etc. have.

Both the first and second digestive chambers 15 and 20 of the multipurpose combined septic tank may be operated by anaerobic digestion, and the first digestive chamber 15 is operated by a high temperature aerobic digestion system and the second digestive chamber 20 May be operated in an anaerobic digestion system, on the contrary, the first digestive system may be operated as an anaerobic digestive system, and the second digestive chamber 20 may be operated as a high temperature aerobic digestive system.

That is, when both the first and second fire-extinguishing chambers are operated in an anaerobic digestion system, the external air control valves 63A and 83A are closed, the shutoff valve 116 is opened, and the shutoff valve 117 is locked. The exhaust control valves 64A and 84A are properly opened, and the underwater aerators 58 and 40 may be all operated.

The first fire extinguishing chamber 15 is operated by a high temperature aerobic extinguishing system, and the second fire extinguishing chamber 20 is operated by anaerobic extinguishing. The external air transfer valve 52 is opened, and the external air control valve 83A is Close, shut off the shutoff valves (120, 121, 117), open the shutoff valves (118, 119, 122). At this time, the external air transfer valve 52 and the external air control valve 63A may be opened. In this case, the underwater aerators 58 and 40 are both operated.

When the first fire extinguishing chamber 15 is operated by anaerobic digestion and the second fire extinguishing chamber 20 is operated by high temperature aerobic digestion, the external air control valve 63A is closed and the shutoff valves 119, 122, 117 are closed. Open the shutoff valves (121,116,118,120). In the case of switching as described above, the initial generated gas is discharged from the gas collection tank so that the air in the exhaust heat discharge tubes 65a and 65b does not enter and remain in the gas collection tank 115, so that only pure gas is stored.

As a more preferable operating method in the operation system for energy recovery as described above, the first fire extinguishing chamber 15 is operated by a high temperature aerobic digestion method and the second fire extinguishing chamber 20 is operated by anaerobic digestion method. By utilizing the oxidative heat energy of the high temperature aerobic microorganism of) as the energy for maintaining the anaerobic digestion temperature of the second digestion chamber 20, it is possible to secure a stable gas volume even in winter and to obtain a larger amount of gas than in the simple anaerobic digestion system. It is a driving method that can.

However, the operation of gas recovery is a matter of choice depending on the amount and concentration of organic matter generated and the utilization of gas energy. For normal purification purposes, both the first and second digestive chambers 15 and 20 have a high temperature aerobic digestion system. Since it is operated as a gas collection tank 115 and a plurality of shutoff and switching valves do not need to be attached as a basic specification. That is, the normal purifying process object is sufficient only with the exhaust heat recovery pipe unit 50 of FIG.

In addition, this multi-purpose merger septic tank is maintained in the high temperature aerobic digestion system, the heat of oxidation of the high temperature aerobic microorganism is preserved, the average temperature in the digestion tank is maintained at 55 ℃ ~ 60 ℃ sterilizing pathogenic bacteria, which is an essential process in other septic tanks Is not necessary. Therefore, since the sterilization and disinfection chemicals are not injected, the ecosystem microorganisms in the discharge water system are protected and the secondary self-cleaning action takes place immediately.

On the other hand, the sand (SAND) flowing into the flow control chamber enlarges the hole (HOLE) of the final exhaust port in the upper part of the flow control chamber to about 150 ψ so that the exhaust pipe can be temporarily removed and the suction pump hose can be pulled out when the sludge is disposed periodically. By doing so, it can be processed without a separate manhole. In the aquatic plant tank (28) of this multipurpose combined septic tank, in addition to the removal of nitrogen and phosphorus, SS remaining in the supernatant from the root of the plant is filtered, and the S-BOD is re-decomposed again to perform the self-cleaning action as in the swamp. You can get it. Therefore, it has a filtration effect even without a separate filtration treatment process.

On the other hand, the above-mentioned multipurpose combined septic tank system of the present invention is suitable for medium and large scale septic tank, and when the septic tank is small according to the use place, it is shown in FIG. 7 (a) instead of the underwater aeration tanks 58 and 40. As described above, external blowers 133 and 143 are installed outside the septic tank, and peripheral devices and pipes are partially configured to perform various functions of the tank-mounted underwater explosion apparatus in the previous chapter.

That is, the external blower 133 for the first fire extinguishing chamber 15 is installed outside the tank, and one of the air suction pipes 132 of the external blower 133 is connected to the outer cylinder of the exhaust heat recovery pipe unit 50 and the other Is connected to the suction pipe 130 of the internal air suction cyclone 129 attached to the inside of the manhole cover 105 of the first fire chamber 15, and control valves 131 and 134 are installed at each connection pipe. The air discharge pipe of the external blower 133 is connected to the air supply pipe 54-1 passing through the first fire chamber 15, and the air supply pipe 54-1 is connected to the air transfer hose 55-1. It is connected to the diffuser 135. On the other hand, the bottom of the first cyclone 59 and the inner air suction cyclone 129 installed inside the manhole cover 105 of the first fire chamber 15, bubbles are bubbled and the drain pipe (so 136 and 137 are installed so that the end is submerged to a certain depth so that air is not sucked into the drain pipe. Therefore, the internal air of the first digestive chamber 15 is sucked into the air vent and the guide vane of the air intake cyclone 129, and after the bubbles are swept through the air intake pipe 130 and the external blower through the air intake pipe 132. The air is supplied to the suction port of 133 and connected to the air discharge pipe of the blower 133 through the air transfer hose 55-1 to generate fine bubbles in the diffuser to cause the supply of oxygen and the flow of water. In the process of recirculating the internal air, the oxygen supply is insufficient to adjust the amount according to the control of the control valve 135 to block and control the preheated external air, the amount of the internal air as much as the supply of external air Oxygen-consumed air is sucked into the air vent and the guide vane of the first cyclone 59, and after the bubbles are deflected, the exhaust heat discharge pipe 65 of the exhaust heat recovery pipe unit 50 through the exhaust pipe 61 of the first cyclone. After the carbon dioxide gas supply pipe 67 is supplied to the aquatic plant tank 28a to be connected to the final exhaust. In the second fire chamber 20, an external blower 143 for the second fire chamber is separately installed outside the tank, and the intake of the outside air and the discharge of the inside air at the same time as the internal air recirculation are performed in the first fire chamber 15. This is done in the same way. However, the air discharge pipe of the external blower 143 for the second fire chamber 20 is divided into a letter 'T', and the electron valves 145 and 146 are installed in each pipe, and the connection pipe 148 connected to one electron valve 146 is provided. The end is connected to the lower part of the air lift pump 149 to supply air for wastewater transfer to the air lift pump 149. The outlet of the air lift pump 149 deviates from the height of the water level detection upper limit 88H of the water level regulator 88 installed in the flow rate adjusting chamber 99 so that the sewage of the flow rate adjusting chamber 99 reaches a predetermined level. When the water level reaches the predetermined level (88H), the timer 85 controls the relay 151 at regular intervals according to the signal of the water level regulator 88 and according to the control of the relay 151. The solenoid valves 145 and 146 open when the other side is closed, and the reverse operation is repeated, and the sewage of the flow rate adjusting chamber 99 is distributed in a certain amount at a predetermined time and is transferred to the second fire chamber 20. Meanwhile, even in the first and second fire extinguishing chambers 15 and 20 in which the external blower is installed, each of the fire fighting chambers can be operated in an anaerobic state. That is, when the external air shutoff valve 134A of the external blower 133 for the first fire extinguishing chamber 15 is closed, the internal gas of the first fire extinguishing chamber 15 is recycled in a state where the oxygen supply is shut off, thereby providing the diffuser 135. It is foamed in and serves to mix the waste water and the generated gas (methane gas, etc.) is collected through the exhaust pipe 61 of the first cyclone 59 and collected in the gas collecting device 115 through the exhaust heat discharge tube (65). It is done. In this case, the shutoff valves 117, 48, and 49 are all closed. In addition, when the second digestion chamber 20 locks the external air shutoff valve 144A of the external blower 143, the internal circulating gas is recirculated in a state where oxygen supply is blocked, and thus anaerobic as in the first digestive chamber 15 is performed. When the solenoid valve 145 is closed and the solenoid valve 146 is opened, the internal gas is supplied to the air lift pump 149 so that the sewage of the flow adjusting chamber 99 is transferred to the second digestion chamber 20 by a predetermined amount. After the sewage transfer, the internal gas is sucked back into the internal air suction cyclone 139 and recycled to the second digestion chamber 20 through the external blower 143. It is also collected by the gas collecting device 115 through the exhaust pipe 81. In this way, the external blower system of the multipurpose combined septic tank can operate each of the fire fighting chambers 15 and 20 as an aerobic fire extinguishing system, as in the previous aeration system. All can also be operated as an anaerobic digestion system, and at the same time as the internal air recirculation, the external air inflow function as necessary and the sewage of the flow control room 99 can be transferred to the second fire extinguishing chamber 20 at a predetermined time. It will have all the functions. On the other hand, as shown in FIG. 7 (b), if the exhaust heat recovery pipe units 50a and 50b are modified, each of the digestion chambers 1 5 and 20 can be operated in one aerobic state and the other in anaerobic state. And vice versa. Such a switching operation method is the same as the operation method in FIG. 7 as described above. In addition, the multipurpose merger septic tank of the present invention includes a merger septic tank composed of only one external blower as shown in FIG. Such a merger septic tank needs to be made simpler in mechanical configuration, or it can become an ideal requirement in an ultra-small merger septic tank. As shown in FIG. 7 (c), the air intake pipe 132 of the external blower 133 has an air intake cyclone 139 inside the second fire chamber 20 as shown in FIG. 7 (c). By being connected to the suction pipe 140 of the internal air of each of the digestion chambers (15, 20) at the same time to enable the external air as much as necessary by the control of the control valve 134A, the adjustment of the internal air intake amount is It is controlled by the suction amount control valve (131, 141). In addition, the air discharge pipe of the external blower 133 is divided into the letter 'T' and the electromagnetic valves 146 and 152 are installed in each of them, and the opening and closing of the external blower 133 is controlled differently by the water level automatic regulator 88, the timer 85, and the relay 151. In the state where the electronic valve 152 is open, each fire fighting chamber through the air transfer hoses 55-1 and 73-1 of the fire fighting chambers 15 and 20 according to the control of the air supply control valves 153 and 154 of each fire fighting chamber. It is supplied to the diffuser (135, 1 47) of the supply of oxygen to the fine bubbles, the surplus air is discharged to each exhaust pipe (130, 140) of each cyclone (129, 139) of each digestion chamber (15, 20). On the other hand, in the state in which the electromagnetic valve 146 is opened and the electromagnetic valve 145 is closed, the exhaust air of the external blower 133 is supplied to the lower part of the air lift pump 149 through the connecting pipe 148 to discharge the sewage of the flow control chamber 99. It serves to transfer to the second fire chamber (20). On the other hand, even in the system having only one external blower, each of the digestive chambers 15 and 20 may be operated by switching all of the digestive chambers 15 and 20 to anaerobic state in the aerobic operation as described above. That is, when the external air shutoff valve 134A is closed, the shutoff valve 116 is opened, and the shutoff valve 117 is held, both the first and second fire extinguishing chambers 15 and 20 are the same as in FIG. 7 (a). It is operated in an anaerobic state. In this manner, both the first and second fire extinguishing chambers 15 and 20 can be operated in an aerobic or anaerobic state and perform the same function as two underwater aerators with only one external blower. However, one of each of the digestion chambers (15, 20) to be aerobic and the other side to anaerobic operation or vice versa is not made.

On the other hand, in the external blower system as shown in Figs. 7 (a), 7 (b) and 7 (c), both the external exposure pipe and the valve and the like are kept warm. . As such an external blower, a diaphragm type air pump, a turbo blower, or a ring blower without oil in the driving unit is preferable.
