The present invention relates to a sewage treatment apparatus installed in the middle of a sewage pipe, and in particular, by controlling the amount of sewage flowing into the sewage treatment plant and purifying the contaminants of the dilute sewage that is overflowed and discharged when the flow rate increases, the sewage treatment plant is discharged to the stream. The present invention relates to a sewage treatment apparatus that improves efficiency and prevents pollution of a river environment.

In general, sewage treatment plants have domestic wastewater from factory wastewater, excreta, and homes, or sewage from nature, and clean the sewage flowing through sewage pipes with clean and safe water to discharge into natural rivers, lakes, etc. Enable reuse with

However, in the past, the diluted sewage generated by the increase of rainwater flowed into the sewage treatment plant through the sewage pipe, so the sewage treatment plant was able to remove the excess amount of sewage flowing into the natural river without purification treatment. I was in a hurry to discharge. In addition, it is true that the dilute sewage that flows from the intermediate device such as rainwater to the existing streams contains various pollutants, and because it is discharged without being purified at least, the natural environment is destroyed by the pollutants. there is a problem.

Therefore, when the amount of sewage increases in the middle of the sewer pipe, a part of the sewage is led to the sewage treatment plant, and the remaining sewage is discharged to natural rivers, lakes, etc. so that the sewage treatment capacity of the sewage treatment plant is operated efficiently. It is true that a processing unit is being installed. However, since the sewage treatment device bypassed some of the sewage to natural rivers with only basic contaminants removed when the amount of sewage increased, it was difficult to prevent pollution of natural rivers, and also installed overflow wear therein. Although sewage is being collected, polluted sewage is discharged into natural rivers, causing the river to be polluted due to the blockage of the sewage treatment device.

It was sent to normal treatment, but the 3Q sewage flowing into the primary sedimentation basin caused problems such as resuspension of sediment. Because of this, the inflow of diluted 3Q sewage, including rainwater, has a problem of lowering the efficiency of sewage treatment due to low organic loads. As a countermeasure, it is true that some sewage treatment plants are installing or planning to separate sediment and solids removal facilities and sedimentation basins for separate overflow water treatment.

Therefore, the present invention improves the efficiency of the sewage treatment plant by improving the amount of sewage and pollution load flowing into the sewage treatment plant when the amount of sewage increases due to the increase of rainwater, and by purifying and discharging the contaminants of the sewage discharged into the streams.

The sixth chambers 17 to 19 are emptied, so that the efficiency of the second and third screen means 83 and 91 is improved, and the water in the fourth to sixth chambers 17 to 19 is increased. This prevents pooling and prevents water from decaying or depositing sediment. Here, the sewage of the fifth chamber 18 is moved to the fourth chamber 17 through the lower space 18b and the first connection hole 7b, and the sewage of the sixth chamber 19 Is moved to the fourth accommodation chamber 17 through the lower space 19b, the second connection hole 9b, the lower space 18b and the first connection hole 7b of the fifth accommodation chamber 18. do.

Meanwhile, the upper space 19a of the sixth accommodation chamber through the sewage moved from the second connecting pipe 87 to the sixth accommodation chamber 19 and the second connection hole 9b and the lower space 19b. The sewage of the fifth accommodation chamber 18 moved to) is purged by the third screen means 91 filled in the sixth accommodation chamber 19 and then opened in the sixth accommodation chamber 19. It is moved to the second accommodation chamber 13 through the upper surface. The third screen means 91 is made of any one of porous media such as sand, activated carbon, ceramic, and membrane to purify sewage from the second connecting pipe 87 between the pores, and then into the sixth storage chamber. It moves to the said 2nd accommodation chamber 13 through the opened upper surface of 19. When the sewage that the third screen means 91 cannot accommodate is introduced into the sixth storage chamber 19, the excess sewage is transferred through the vertical pipe portion 87a of the second connecting pipe 87. It is moved to the storage chamber 13.

As shown in Figs. 10 to 12, for example, as the rain falls, the first accommodation chamber 11 is overflowed by an increase in the amount of sewage, and the first to third screen means 60, 83, 91 are sequentially passed. The sewage that has been purged and moved to the second accommodation chamber 13 is discharged to the stream through a bypass pipe 92 provided on the wall of the body 1 in contact with the second accommodation chamber 13. The sewage discharged into the river through the bypass pipe 92 is a state in which various contaminants have been removed, thereby preventing pollution of the river, thereby greatly preventing environmental pollution.

As shown in Figs. 11 and 12, for example, a large amount of sewage flows into the first accommodation chamber 11 due to heavy rain, and the amount of sewage flowing through the first accommodation chamber 11 overflows the first screen means 60. In case of exceeding the capacity of 1), the first screen means 60 is discharged to the river through the bypass pipe 92 by sending the sewage which is not accommodated as it is in the second storage chamber 13, Between the sewer pipe (P) and the sewage inlet pipe (21) forms a hollow structure with both ends opened, but the sewer pipe connecting pipe 93 is formed by protruding the weir (93a) of a certain height from the bottom in the middle of the sewer pipe Allow the connecting pipe 93 to stably guide the sewage from the sewage pipe P to the sewage inflow pipe 21, but when the excess flow rate occurs in the first accommodation chamber 11, a part of the weir ( 93a) from the sewage inflow pipe 21 By setting the by-pass, and manages the wastewater efficiently.

As described above, according to the present invention, by controlling the amount of sewage flowing into the sewage treatment plant and purifying the contaminants of the dilute sewage that is overflowed and discharged when the flow rate increases, the sewage treatment plant is discharged to the stream to improve the treatment efficiency of the sewage treatment plant and the water quality. It has the effect of greatly preventing environmental pollution.
