Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a septic tank for treating and purifying sewage such as human waste and miscellaneous wastewater discharged from a house or the like, and relates to a septic tank with a base on which a discharge pump tank is mounted.
[0002]
[Prior art]
When discharging treated water that has been treated and purified in a septic tank, if the discharged water is far and naturally flowing, and the treated water does not flow to the discharged water, or if the height of the discharged water is higher than the height of the discharge outlet In general, a septic tank discharge pump tank is provided in the septic tank main body (in reverse slope).
[0003]
8 and 9 show a conventional example of a purification tank having a discharge pump tank. A concrete bottom plate 11 is laid to install the septic tank main body 1a and the discharge pump tank 2, and a septic tank main body 1a and a discharge pump tank 2 (a tank independent of the septic tank main body 1a) are provided thereon as shown in the figure. The discharge port 6 of the septic tank main body 1a and the inflow port 7 of the discharge pump tank 2 are connected by a pipe 8, and the treated water from the septic tank main body 1a is transferred to the discharge pump tank 2.
[0004]
[Problems to be solved by the invention]
However, in the structure as shown in FIGS. 8 and 9, when the height of the septic tank main body 1a and the discharge pump tank 2 are different, the concrete bottom slab 11 supporting the discharge pump tank 2 is further raised as shown in FIG. (A step is formed on the concrete bottom slab 11). Further, in such a structure, the installation area of the entire septic tank needs to be secured relatively large.
[0005]
The present invention solves such a problem, that is, even if the height of the septic tank main body 1a and the discharge pump tank 2 are different, there is no need to make a step on the concrete bottom slab 11, and the entire septic tank is installed. An object of the present invention is to provide a septic tank that does not require a large area.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has the following configuration. That is, the septic tank of the present invention includes a septic tank main body, a pedestal fixed to a discharge port side of an outer tank of the septic tank main body by a fixing means, and a discharge pump tank mounted on the pedestal. The discharge pump tank is a purification tank connected by a pipe . Moreover, the pedestal is also a septic tank in which a base is fixed by bolts together with a reinforcing plate attached to an outer tank of the septic tank body .
[0007]
[Action]
The discharge pump tank can be installed on the base for mounting the discharge pump tank. For this reason, a concrete bottom slab having a different level, which was conventionally required (for installing a discharge pump tank), becomes unnecessary.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the accompanying drawings. 1 to 3 show a septic tank 1 according to an example of the present invention in which a pedestal 3 is attached to a side surface (a discharge port side) of a septic tank body 1a. The inside of the septic tank is omitted, but from the upstream side, the anaerobic treatment tank (anaerobic filter bed tank first room, anaerobic filter bed tank second room, etc.), aerobic filter bed tank, treated water tank (or sedimentation tank), disinfection tank , And an aeration tube is arranged below the filter bed of the aerobic filter bed tank. Further, a blower (not shown) for sending air to the aerobic filter bed tank or the like is provided, and a manhole and a manhole cover for closing the manhole are provided so that the inside of each tank can be inspected from above.
[0009]
The pedestal mounting part is shown in FIG. The pedestal 3 is made of five molded plates in FIG. 4 and is formed in a triangular pyramid shape, and one surface of the triangular pyramid is shaped along the discharge tank side outer tank of the purification tank main body 1a. The triangular pyramid-shaped surface is aligned with the discharge port side of the septic tank main body 1a, and the height of the pedestal 3 is adjusted so as to match the height of the discharge pump tank 2. It is fixed to the septic tank main body 1a with 10 and an adhesive.
[0010]
Thereafter, the discharge pump tank 2 is placed on the fixed base 3, and the discharge port 6 of the septic tank main body 1a and the inlet 7 of the discharge pump tank 2 are connected by a pipe 8. It is a septic tank shown in FIGS.
The connection between the septic tank main body 1a and the pedestal 3 can be made by using only an adhesive or only an overlay in addition to the bolt and the adhesive.
[0011]
The pedestal 3 depends on the material, but is usually formed of a plastic molded plate made of FRP, dicyclopentadiene or the like having a thickness of about 10 mm to 15 mm, or a metal molded plate made of stainless steel, aluminum, iron, or the like. It is shaped like a cone. One surface of the triangular pyramid is formed along the outer tank on the outlet side of the septic tank main body, and the surface is fitted to the outer tank portion and attached to the septic tank main body 1a by fixing means such as a bolt or an adhesive. In addition, when the discharge pump tank becomes unnecessary, the base is configured to be removable.
[0012]
【The invention's effect】
In the septic tank of the present invention, the entire size of the septic tank is almost similar to the size and shape before the discharge pump tank is attached, and if this is used, there is no need to make a step on the concrete bottom slab of the foundation. Also, the construction is easy.
