によって汚濁物質（有機質）を分解せしめる機能を備え
る。Conventionally, a dedicated residential septic tank consists of a sedimentation tank (first treatment tank section) that performs pretreatment, a biological oxidation tank (second treatment tank section) that performs main treatment, a sedimentation tank (third treatment tank section), and a disinfection tank. (4th treatment tank section), and urine, urine and gray water (sewage) discharged from residences were sequentially supplied to the six tanks for purification treatment and discharged into river J1, etc. The sedimentation separation tank separates sediment and suspended matter from wastewater, and sends the treated water from which these have been removed to the next biological oxidation tank.The biological oxidation tank also uses the supplied treated water for a certain period of time It has the function of storing pollutants (organic substances) for at least 5 hours (depending on the processing method, outside temperature, etc.) and decomposing pollutants (organic substances) using microorganisms.
ところで、住宅における汚水の排出時間は断続的である
とともに、第９図の棒グラフから明らかなように、汚水
排出量＆、ｂＳ ｅ・・・は時刻によって大きく変動す
る。ちなみに午前７：００から午前１０：００の時間帯
では一日における全排出量の４０〜４５％程度が排出さ
れる。By the way, the discharge time of sewage in a house is intermittent, and as is clear from the bar graph in FIG. 9, the amount of sewage discharged &, bSe, etc. varies greatly depending on the time. By the way, between 7:00 a.m. and 10:00 a.m., about 40 to 45% of the total amount of water emitted in a day is emitted.
このため、かかる時間帯では一時的に増水し、特に、生
物酸化槽では十分な処理時間を経ないまま、次段の沈澱
槽（第三処理槽部）に送られ、浄化機能が大きく低下し
てしまうという問題があった。As a result, the water temporarily increases during these times, and in particular, in the biological oxidation tank, the water is sent to the next settling tank (third treatment tank) without sufficient treatment time, greatly reducing its purification function. There was a problem with this.
なお、この問題を解決するには浄化槽の容量を大きくす
ればよいが、専用住宅用の場合、浄化槽の大型化は設置
場所が限られるため、採用できない。Although this problem can be solved by increasing the capacity of the septic tank, it is not possible to increase the size of the septic tank for private residences because of the limited installation space.
本発明はこのような従来技術に存在する課題を解消した
汚水処理槽用流Ｊｉｍ整装置の提供を目的とするもので
ある。The object of the present invention is to provide a flow adjustment device for a sewage treatment tank that solves the problems that exist in the prior art.

一時的な増加は緩衝される。According to the flow rate adjustment device 1 for a sewage treatment tank according to the present invention, the treated water W in the sewage treatment tank section 4 is controlled by the action of the air lift pump 5 located between the adjustment tank section 4 and the second treatment tank section 3. A fixed amount is transferred to the second processing tank section 3. On the other hand, when the amount of wastewater discharged temporarily increases and the amount of treated water W flowing out from the first treatment tank section 2 increases, the predetermined increased amount is temporarily stored in the adjustment tank section 4. A temporary increase in treated water W in the second treatment tank section 3 is buffered.
以下には、本発明に係る好適な実施例を挙げ、図面に基

It is discharged into rivers etc. via
次に、流量調整装置１の具体的構成について第１図を参

る。First, between the first processing tank section 2 and the second processing tank section 3,
An adjustment tank section 4 having a relatively small volume is installed above it. Further, the adjustment tank section 4 and the first processing tank section 2 are connected by a water pipe 14. The water pipe 14 is formed in a horizontal strip shape, and its vertical pipe portion 14p is disposed in the first processing tank ff2, and the inlet 14Q at the lower end is disposed approximately in the middle of the processing tank portion 2 in the vertical direction.

入させるバイパス管である。On the other hand, the bottom of the adjustment tank section 4 and the top of the second processing tank section 3 are connected via an air lift pump 5. air lift pump 5
is provided with a vertical suction pipe 16 and a lift pipe 17, and the lower ends of the suction pipe 16 and the lift pipe 17 are connected to each other by a connecting pipe 18 which is inclined with the lift pipe side slightly upward, forming an N-shape. The upper end opening of the suction pipe 16 is connected to the adjustment tank section 4, and the upper end opening of the water pumping pipe 17 is made to face the inside of the second processing tank section 3. Further, an aeration pipe 22 is disposed inside the lift pipe 17, and an air outlet 21 provided at the tip thereof is located near the lower end of the lift pipe 17. On the other hand, the other end of the aeration pipe 22 is connected to an air pump 24 via an on-off valve 23. The amount of air supplied by the air pump 24 can be adjusted. Note that 25 is a bypass pipe that allows the treated water W overflowing in the adjustment tank section 4 to flow into the second treatment tank section 3.
次に、本発明に係る流量調整装置１の機能について説明
する。Next, the functions of the flow rate adjustment device 1 according to the present invention will be explained.
まず、エアポンプ２４を作動させれば、エアが空気噴出
口２１から噴出し、気泡は揚水管１７に沿って上昇する
。First, when the air pump 24 is activated, air is ejected from the air ejection port 21 and bubbles rise along the water pump 17.

容され、汚水が一定の高さまで上昇すれば、浮遊物と沈
澱物が分離された汚水、即ち、処理水Ｗが送水管１４を
通って調整槽部４内に流入する。Now, when sewage is discharged from a house, it is stored in the first treatment tank section 2, and when the sewage rises to a certain height, the sewage from which floating matter and sediment have been separated, that is, the treated water W, is transferred to the water pipe. 14 and flows into the adjustment tank section 4.

部４内の処理水Ｗが無くなれば、エアリフトポンプ５に
よって移送される処理水Ｗの量は急激に低下し、揚水管
１７の所定レベルまで低下すれば、揚水は停止する。When the treated water W accumulates in the adjustment tank section 4, the apparent specific gravity of the treated water in the intermediate pipe 17 decreases due to the pumping action of the air lift pump 5, that is, the air bubbles ejected into the pumping pipe 17. , an amount corresponding to the difference in specific gravity of the original treated water is pumped up and sent to the second treatment tank section 3. The treated water W sent to the second treatment tank section 3 is transferred in a fixed amount, which is determined by the capacity of the air lift pump 5 and the like. As a result, the first treatment tank section 2
If the amount of water flowing into the adjustment tank section 4 is large, the increased amount will be stored in the adjustment tank section 4. Note that when the treated water W in the adjustment tank section 4 runs out, the amount of treated water W transferred by the air lift pump 5 decreases rapidly, and when the amount decreases to a predetermined level in the pumping pipe 17, pumping stops.

,, b If Sc... becomes larger than the amount S of water quantitatively transferred from the air lift pump 5 to the second treatment tank section 3,
An increased amount M shown by diagonal lines in the figure is stored in the adjustment tank section 4, and the amount of water flowing into the second processing tank section 3 is adjusted so as to be always constant.

The air lift pump 5b shown in the figure is H-shaped, and the air lift pump 5C shown in FIG. 4 is Y-shaped. The shape of the air lift pump is not limited to these examples, and can be arbitrarily changed without impairing the function. In this case, none of the air lift pumps 5.5a, 5b, 5e should ensure that no air bubbles are blown up into the suction pipe 16.16a and that the suction pipe I

In this embodiment, two units are used, namely, the master unit, which is the original flow rate adjustment device, is placed in the first stage, and the slave unit, which is a relatively small-scale flow rate fine adjustment unit 30, is used in the second stage. The wastewater sucked up from the first treatment tank part 2 by the air lift pump 5 is temporarily stored in a small capacity fine adjustment seed part 31 installed inside the adjustment tank part 4, and the fine adjustment seed part 31 is Sewage was sent to the second treatment tank section 3 by an air lift pump 32. In this case, a steady water surface that remains constant is obtained in the fine adjustment seed section 31 from beginning to end, and overflowing wastewater is returned to the adjustment tank section 4. Therefore, the amount of water pumped into the second treatment tank section 3 can be finely adjusted. In addition, 33 is a diffuser pipe, 3
