問題点があった。(Prior art and its problems) Conventionally, a septic tank formed in an oblong shape has been used to treat wastewater, and this septic tank contains a flow rate adjustment tank, @
The air tank, sedimentation tank, disinfection tank, etc. are separated and installed internally, but since conventional septic tanks are horizontal, the installation area is correspondingly large, and the foundation for installation is required. There was a problem in that the construction work was labor-intensive, and in the case of a horizontal type, a considerable amount of space was formed at the top, resulting in a problem in that the throughput was small compared to the volume.

成したことである。(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems, and provides a vertical septic tank that has excellent processing capacity, has a small installation area, and can save labor in foundation work, etc. The purpose of this is to install an aeration tank on the lower side through an inclined partition.
A settling tank is arranged on the upper side, and the whole is formed into a vertically elongated shape, and the upper end of the partition is raised to make the top opening area of the aeration tank small and the top opening area of the settling tank large. That's what I did.

できる。(Function) The aeration tank and sedimentation tank are formed compactly through the partition, and since the whole is made vertically long, the installation area can be reduced, and the foundation work can be carried out on a smaller scale. Moreover, because it is vertically long, there is less space at the top,
The actual amount of water increases, making it possible to increase the throughput.The aeration tank that is formed is located on the lower side, increasing the water depth, increasing oxygen dissolution efficiency, and making it possible to use smaller aeration devices installed inside. Moreover, since the opening area of the upper surface is small, defoaming on the upper surface side can be facilitated. or,
The sedimentation tank can have a deep water depth, and can also have a large opening area on the upper surface side to improve solid-liquid separation performance.
（実施例） 以下、本発明の実施例を図面に基づいて説明する。(Example) Embodiments of the present invention will be described below based on the drawings.

止界面Ｗの上方には上部空間Ｓが形成される。In the figure, a first tank 1 constituting a septic tank is formed of FRP in a vertically elongated shape, and the bottom and top surfaces are formed in a sealed shape. Inside this first tank 1, there is a side wall 1a.
The inclined plate 2a is disposed in an upwardly inclined manner at an angle of about 30 degrees from the top, and the upper end of the inclined plate 22 is a rising plate 2b which is raised vertically. This standing board 2b
A stationary interface W is formed within the tank 1 at a position below the upper end, and an upper space S is formed above the stationary interface W.

部は大面積に形成きれている。In this example, it is partitioned by an inclined plate 2a, and an aeration tank 3 is formed on the lower side, and a settling tank 4 is formed on the upper side. Therefore, the aeration tank 3 is long in the vertical direction so that a sufficient water depth can be ensured, and the opening on the top surface has a small area because the upright plate 2b is disposed toward the left side in the figure. On the other hand, the upper opening of the settling tank 4 has a large area.

It can be aerated. Further, an overflow weir 9 is provided around the stationary interface W on the upper surface side of the settling tank 4. In addition, a center well 7 is erected in the center, and an advection pipe 8 is connected from the aeration tank 3 side in communication with the center well 7.

面側の越流せき９を越えて処理水が外部に排出される。In such a configuration, the sewage that has been aerated and mixed with sludge in the aeration tank 3 passes through the advection pipe 8 to the settling tank 4.
Solid-liquid separation is performed within this sedimentation tank 4, and the treated water is discharged to the outside over an overflow weir 9 on the upper surface side.

で足りる。Incidentally, since the opening area of the upper surface of the aeration tank 3 is extremely narrow, even if bubbles are generated on the upper surface side, the bubbles can be easily extinguished. Furthermore, since the water depth of the aeration tank 3 is deep, the oxygen dissolution efficiency is high, and the number of aeration devices 6 is smaller than that of a horizontal type, so that the amount of air that can be blown out can be small.
又、前述した如く、沈殿槽４の上面開口面積は大に形成

ておくと、水の充填、排出に便利である。Furthermore, as mentioned above, since the opening area of the upper surface of the settling tank 4 is large, the length of the overflow weir 9 can be increased accordingly, and the solid-liquid separation performance is improved. . Further, the water depth on the bottom side can be made deep along the inclined plate 2a, and sludge can be accumulated on the bottom side well. Incidentally, if a hole 10 for communication is formed in the inclined plate 2a, it is convenient for filling and discharging water.

できるものとなる。In addition, in this example, since it is formed in a vertical shape, the upper space S
Compared to the horizontal type, the space is significantly smaller than that of the horizontal type, so there is no waste, and the actual amount of water can be increased to improve the throughput. In addition, since it is vertical, the area of land required to install this first tank 1 is small, and the area required for foundation work is also small, making it possible to use the land effectively and reducing installation work. can be carried out more easily and on a smaller scale than before.

とができる。The second tank 11 configured in this manner can be installed in parallel with the first tank 1 and connected to each other through piping to function as a purification device. For example, wastewater to be treated is first transferred to the flow rate adjustment tank 2 The sludge is then transferred to the aeration tank 3 for aeration treatment, then transferred to the settling tank 4, and the sludge that has settled at that time is returned to the aeration tank 3 using an air lift or the like, and the surplus is used for the sludge concentration. The treated water can be transferred to the storage tank 25, and the treated water exceeding the overflow weir 9 of the settling tank 4 can be discharged to the outside from the discharge pump tank 23 through the disinfection tank 22, forming a good sewage treatment device as a whole.
