Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

The present invention relates to a small ozone / wastewater purification tank for treating ozone / wastewater and a small ozone / wastewater purification tank constructed by the method. Since it can be constructed using an equilibrated product such as a concrete manhole and a humidifier, The cost can be reduced and the strength of the prefabricated concrete manhole to serve as the structure of the septic tank is excellent, so that the required strength of the septic tank can be easily satisfied.

A method for constructing a small-scale waste water / wastewater purification tank according to the present invention comprises the steps of: a) preparing a prefabricated concrete manhole (10) having a rectangular or circular cross section and a prefabricated sewage pipe (20) having a smaller cross section than the concrete manhole (10) ; b) forming an inlet port (11) and an outlet port (12) on the sidewall of the concrete manhole (10) and forming two connecting ports (21) in the sewer pipe (20); c) disposing a sewer pipe (20) in a space in the concrete manhole (10); d) placing and curing the concrete (C) on the inner and outer peripheries of the pipe (20) for sewerage; And e) connecting the inlet (11) or the outlet (12) of the concrete manhole (10) with a connection port (21) of the sewer pipe (20).

Fig. 1 is an explanatory diagram for explaining a construction method of the small-scale waste water / wastewater purification tank according to the present invention in order.

Hereinafter, the construction method of the small waste water / wastewater purification tank will be described step by step.

a) preparing the ready-made concrete manhole 10 and the sewer pipe 20 (Fig. 1 (a));

Prepare products manufactured and commercialized at the factory.

The concrete manhole 10 may be formed in a box shape in order to construct a manhole, and the sewage pipe 20 may be a hume pipe or a plastic pipe manufactured for constructing the main and sewage main pipes. In the step c), since the sewer pipe 20 is disposed in the concrete manhole 10, the cross section of the sewer pipe 20 should be smaller than the cross section of the concrete manhole 10.

The length of the sewage pipe 20 may be less than the height of the concrete manhole 10, so that the work can be performed using a cutter. In order to more accurately control the capacity of the sewage pipe 20 serving as a tank after completion of the construction of the septic tank, the pipe 20 having different diameters is connected in the longitudinal direction to connect the sewage pipe 20 You can also make it.

In FIG. 1, the cross section of the concrete manhole 10 is shown as being square. However, some of the conventional concrete manhole products may have a circular cross-section.

b) hole forming step in the prepared concrete product (Fig. 1 (b));

The prepared concrete manhole (10) is only opened at the upper part, and the sewage pipe (20) is opened only at both ends, thus forming holes for the inflow and outflow of waste water and wastewater.

The distance from the bottom of the concrete manhole 10 to the inlet 11 and the outlet 12 and the distance from the one end of the pipe 20 for sewage to the connection 21 are different from each other, · Wastewater can flow in a certain direction.

The inlet 11 and the like can be formed by piercing the concrete manhole 10 or the like using a core drill.

c) disposing a sewer pipe 20 in the concrete manhole 10 (Fig. 1 (c));

A sewage pipe (20) is placed upright at a predetermined position of the inner space of the concrete manhole (10).

Accordingly, the space inside the concrete manhole 10 is divided into a space inside the sewage pipe 20 and an external space, and a space outside the sewage pipe 20 serves as an outer surface of the concrete manhole 10, (10) so as to be in contact with the inner surface of the housing (10).

Each of these spaces serves as a tank for each stage of the waste water treatment.

When the sewer pipe 20 is disposed in the concrete manhole 10, a connecting hole 21 for facilitating the following step e) is formed in the inlet 11 or the outlet 12 of the concrete manhole 10 To be on the same line.

d) Placing concrete (C) in and out of the sewage pipe (20); curing step (Fig. 1 (d));

Concrete C is placed and cured in the sewage pipe 20 placed in the concrete manhole 10 and on the outer peripheral surface of the sewer pipe 20 to fix the position of the sewer pipe 20 and to hold the concrete manhole 10 ) And the lower surface of the sewage pipe (20).

Accordingly, the sewage pipe 20 and the concrete manhole 10 become one integrated structure, and the spaces inside and outside the sewage pipe 20 are completely closed with each other except for the upper portion thereof and the connector 21 .

1 (d), an exponent rubber R is disposed on the edge of the space in the sewage pipe 20 facing the bottom surface of the concrete manhole 10, have.

The bottom surface of the concrete manhole (10) and the bottom surface of the inner and outer surfaces of the pipe (20) for sewage can be previously roughened to improve the integrity with the concrete (C) laid in this step.

Since the sewage pipe 20 has a closed cross-sectional shape and can serve as a formwork, it is not necessary to provide a separate formwork for this step.

e) a step of connecting the concrete manhole 10 and the sewer pipe 20 (Fig. 1 (e));

A connection port 21 of the sewage pipe 20 is connected to an inlet port 11 or an outlet port 12 of the concrete manhole 10 so that the waste water flowing through the inlet port 11 of the concrete manhole 10 flows into the sewer pipe 10, So that it can flow out to the outlet 12 through the pipe 20.

1 (e), the outlet 12 of the concrete manhole 10 is connected to a connecting port 21 of the sewer pipe 20. In this case, the remaining connector 21 of the sewage pipe 20 allows the space inside the concrete manhole 10 to communicate with the internal space of the sewage pipe 20 outside the sewage pipe 20. The waste water flowing into the concrete manhole 10 through the inlet 11 of the concrete manhole 10 is discharged to the outlet 12 of the concrete manhole 10 through the inner space of the pipe 20 for sewage, do.

As described above, the height of the inlet 11, the outlet 12, and the connecting hole 21 may be different from each other, and the ozone / wastewater may flow naturally from a high place to a low place. Of course, in FIG. 1 (e), it is preferable that the holes connected to each other like the outlet 12 and the connector 21 are located on the same height.

The connection between the connection port 21 and the outlet 12 (or the inlet) is made through a short connection pipe L having a cross-sectional size equal to the cross-sectional size of the connection port 21, 21 to seal the connection between the concrete manhole 10 and the sewage pipe 20 with a watertight structure.

As described above, in the method of constructing the small-sized waste water / wastewater purification tank according to the present invention, since the conventional concrete manhole already constructed to have excellent strength constitutes the main structure, the required strength of the purification tank 1 can be easily satisfied, It is not necessary to construct a concrete structure, and only an off-the-shelf product can be purchased and processed with a simple construction tool, which can greatly reduce effort, time and cost required for construction.

In addition, since the sewage pipe 20 has a plurality of spaces separated from the sewage pipe 20 in spite of its small size, the waste water can be effectively treated through a plurality of stages.

As described above, the cross section of the concrete manhole 10 can also be formed in a circular shape, and in FIG. 2, the waste water and wastewater purification tank after the step e) is shown in the case where the cross section of the concrete manhole 100 is circular.

After the step d), an operation of installing an aeration device, a flow rate control pump, and the like may be performed in the concrete manhole 10, and after the step e), a manhole cover may be installed on the concrete manhole 10 . These operations are not so different from those in the conventional septic tank construction method, so a detailed description thereof will be omitted.

As shown in Fig. 1 (e), the septic tank 1 having two large spaces in the concrete manhole 10 can be used as a simple septic tank. The space S1 outside the sewage pipe 20 connected to the inlet 11 serves as a decay tank and serves to filter the solid foreign substances and the space S2 inside the pipe 20 for sewage connected to the outlet 12, Serves as a filtration tank.

Alternatively, two or more sewer pipes 20 may be used in the method of constructing the small-sized waste water / wastewater purification tank according to the present invention. In this case, the sewer pipes 20 are connected to each other in step e). The cross-sectional dimensions of each sewer pipe 20 may be the same or different.

Fig. 3 shows an example of the purified water tank 1 constructed when two sewage pipes 20 are used, and Fig. 4 shows an example of the purified water tank 1 constructed when three sewer pipes 20 are used. When two or more sewage pipes 20 are used, the number of spaces in the concrete manhole 10 is further divided into several, so that a purification tank having a better purification efficiency can be constructed.

For example, the septic tank 1 as shown in FIG. 3 can be used for general sewage treatment. The space S3 outside the sewage pipes 20 is connected to the inside of the flow control tank, the inside of the large sewage pipe 20 And the space S5 inside the small sewage pipe 20 serves as a settling tank and the septic tank 1 as shown in Fig. 4 is used for the sake of advanced treatment or wastewater treatment The spaces S6, S8 and S9 inside the pipes 20 for sewage serve as an anoxic tank, a reaction tank, and a settling tank, respectively. .

When two or more sewage pipes 20 are used in the method of the present invention, the sewage pipes 20 in the step c) are arranged such that their outer surfaces are arranged adjacent to each other, The space inside the concrete manhole 10 outside the sewage pipe 20 can be divided into a plurality of compartment spaces P.

Each of the plurality of compartment spaces P serves as a separate tank to further refine the purification process of waste water and waste water, thereby improving the efficiency of purification.

The sewer pipes 20 may be arranged such that the outer surfaces thereof are disposed adjacent to each other or adjacent to the inner surface of the concrete manhole 10, and the gap G is formed at least at one of the adjacent portions. As a result, each of the compartment spaces P communicates through the gap G. [

The interval (G) serves to filter the solid matter in the waste water and wastewater. When the sewage pipe 20 is disposed such that the waste water flows sequentially through the inlet 11 of the concrete manhole 10, the plurality of compartment spaces P and the connecting port 21 of the sewer pipe 20 , The path to enter the inner space of the sewage pipe 20 serving as a reaction tank becomes longer, so that a small solid matter precipitates and is separated naturally.

3, the space S3 outside the sewer pipes 20 is divided into three compartment spaces P, between the first compartment space and the second compartment space, the second compartment space and the third compartment space 4, the space S6 outside the sewer pipes 20 is divided into the four compartment spaces P, and the space S is formed between the compartment spaces. To remove solids over three times.

When the gap G is formed in at least two of the sewer pipes 20 and adjacent portions of the sewer pipe 20 and the concrete manhole 10, The tubes 20 can be arranged.

When the widths of the gaps G are different from each other, the solids filtered at the gaps G are different from each other, as in the case of arranging a plurality of sieving nets having different pore sizes, so that the solids can be filtered out more effectively.

On the path where the waste water flows, the gap (G) is formed to be gradually smaller, so that large solid matter should be filtered first.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. And thus fall within the scope of the present invention.
