The present invention relates to a sewage discharge structure of a sewage sedimentation tank that sediments sludge and microbial particles contained in sewage and releases comparatively clean sewage, and will be described in more detail with reference to the drawings.

As shown in FIGS. 1 and 2, the sewage sedimentation tank according to the present invention is formed in a circular shape like a conventional sedimentation tank, and receives the introduced sewage water.

In the present invention, the water tank 10 is limited to a circular shape, but it may be formed into a rectangular shape as shown in FIG.

The water tank 10 is formed with an inlet means 20 for drawing sewage from the outside and discharging the sewage water. The inlet means 20 includes a water inlet pipe 21 Is drawn into the water inlet pipe 21 and discharged to the water tank 10 again.

At this time, the discharge of the sewage is discharged downward from the upward direction, and in the water tank 10, the sewage discharged by the inlet means 20 conveys downwardly from the upward direction to the upward direction from the downward direction, The settling zone A in which the microbial particles and the sludge contained in the settling zone A are formed.

At least one or more sewage inlet horizontal collecting pipes (30) are arranged radially with respect to the inlet means (20) so that sewage located in the upper portion of the settling zone (A) flows To the outer periphery of the water tub (10).

A plurality of inflow holes 31 are formed at regular intervals along the upper surface of the sewage inflow horizontal collector pipe 30 so that the inlet means 20 discharges the sewage, (A), and is transported to the outer periphery of the water tank (10) through the sewage inflow horizontal collecting pipe (30).

As shown in FIGS. 4 to 6, the ultraviolet lamp 33 is further installed in the sewage inflow horizontal collector pipe 30 to emit ultraviolet rays into the sewage inflow horizontal collector pipe 30, In addition to preventing moss and green tide from being generated in the sewage inflow horizontal sewage pipe 30, the coliform bacteria contained in the sewage (total coliform bacteria at a rate of 3000 pcs / ml or less) are sterilized by ultraviolet rays.

Conventionally, chlorine has been used to sterilize Escherichia coli contained in sewage. In this case, since chlorine remains in the sewage and chlorine-containing sewage is discharged into the natural environment, it not only affects the aquatic ecosystem, .

Therefore, ultraviolet rays are irradiated to the wastewater discharged to nature, and conventionally chlorine It is possible to solve the problems caused by the use thereof.

In order to insulate and protect the ultraviolet lamps 33, the ultraviolet lamps 33 may be made of quartz or glass, Ideally, it should be constructed inside a closed transparent tube.

A mixing screw 32 in the form of a screw is formed along the outer circumferential surface of the ultraviolet lamp 33 along the longitudinal direction of the sewage inflow horizontal collector pipe 30.

The hydrogen peroxide is injected into the injection pipe through the supply pipe And flows into the sewage inflow horizontal collecting pipe (30).

The hydrogen peroxide introduced into the sewage inflow horizontal sewage pipe 30 reacts with ultraviolet rays irradiated from the ultraviolet lamp 33 to cause high oxidation in the sewage inflow horizontal sewage pipe 30, Promoting decomposition of organic matter.

The hydrogen peroxide injection unit 34 is connected to the sewage inflow horizontal collector pipe 30 A guide 35 is formed in the periphery of each hole into which the hydrogen peroxide flows. The guide 35 protrudes into the sewage inflow horizontal sewage pipe 30 with a predetermined length, and the sewage inflow horizontal sewage pipe 30, The hydrogen peroxide is prevented from being immediately released due to the flow rate and is diffused into the sewage inflow horizontal collecting pipe 30 when the hydrogen peroxide flows into the sewage inflow horizontal collecting pipe 30.

A brush member 80 for cleaning the upper surface of the sewage inflow horizontal collector pipe 30 to prevent moss and green tide from being generated in the inflow hole 31 of the sewage inflow horizontal sorter pipe 30 is further provided As shown in FIGS. 2 and 3, the brush member 80 is rotated by the rotor 70 while the inlet means 20 is pivoted about the axis of the sewage inflow horizontal collector pipe 30 Clean the top surface.

More specifically, the rotor 70 is disposed on the upper portion of the inlet means 20, and the rotary bar 72 is coupled to the rotary shaft 71 of the rotor 70.

The brush member 80 is connected to a lower portion of the rotary bar 72 of the rotor 70 so that the rotor 70 is rotated by rotation of the rotary bar 72 in accordance with driving, The upper surface of the cleaning cloth 30 is cleaned.

A sludge discharge pipe 40 is formed in the bottom of the water tank 10 to collect microbial particles and sludge settled in the bottom of the water tank 10 and discharge it to the outside.

Also, a pivoting blade for rotating the inlet means 20 is provided so that the sludge is not loaded.

The structure of the sludge discharge pipe 40 is also provided in a conventional sewage sedimentation tank, and a detailed description thereof will be omitted.

1, a first drainage passage 50 is formed along the upper periphery of the water tank 10 to discharge sewage introduced through the sewage inlet horizontal collector pipe 30, The overflow wall 51 of the first drainage passage 50 is formed in the outer wall surface of the first drainage passage 50 so that the sewage of the first drainage passage 50 is discharged in an overflow manner, And a second drainage passage 90 for guiding the discharged sewage to the outside can be formed.

The overflow weir 51 may be configured to be raised and lowered by the elevating means to adjust the discharge water level and the discharge amount of sewage.

A water channel cover 60 is formed on the upper surface of the first water channel 50 to cover the upper surface of the first water channel 50 so as to prevent sunlight from penetrating into the first water channel 50, And opens and closes the upper surface of the first drainage path (50).

7, when the water tank 10 is formed in a rectangular shape, the sewage inlet horizontal collecting pipes 30 are arranged in a row, and the side surface of the rectangular water tank 10 is arranged in a line And a brush member 80, which linearly reciprocates by a driving means, may be formed on the upper portion.
