Description

Overflow water treatment device {apparatus for treating rainwater}

The present invention relates to a overflow water treatment apparatus, and more particularly, to regulate the amount of sewage flowing into the sewage treatment plant and to purify the pollutants of the dilute sewage that is discharged and discharged when the flow rate increases, and to discharge the sewage treatment plant to improve the efficiency of the sewage treatment plant. In addition, the present invention relates to a overflow water treatment system that greatly prevents pollution of the 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, since the diluted sewage generated by the increase of rainwater flowed into the sewage treatment plant through the sewage pipe, the sewage treatment plant was discharged to 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 the existing rainwater chamber 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 device is being installed. However, since the sewage treatment apparatus has bypassed some of the sewage to natural rivers while removing only basic contaminants when the amount of sewage is increased, it is difficult to prevent contamination of natural rivers, etc. 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.

In addition, in the past, sewage treatment plants have treated sewage or solids from primary sedimentation basins, for example, from 3Q sewage by sewage facility standards, and 2Q sewage is discharged through bypass channels, and the remaining 1Q sewage is treated as sewage treatment. 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.

An object of the present invention is to improve 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.

According to the present invention, the sewage moving to the sewage treatment plant through the sewage pipe is introduced into the first accommodation chamber 112 of the manhole-shaped body 100 through the inlet pipe 102. Thus, the sewage flowing into the sewage is filtered by a large volume of foreign matter in the swirl screen 210 of the first purification treatment means 200 installed in the first accommodation chamber 112, and the sedimentary foreign matter by the sedimentation tank 220. This is filtered. At this time, the foreign matter filtered in the swirl screen 210 and the settling tank 220 is moved to the foreign matter transport path 118 provided in the lower portion through the foreign matter discharge pipe (212). In addition, the sewage passing through the settling tank is suspended (부상 上) to filter the suspended foreign matter. At this time, the floating foreign matter is moved to the foreign matter transport path 118 through the foreign matter discharge hole (118a) by the diffuser 132.

In addition, the sewage that has passed through the first purification treatment means 200 passes through the aggregate 320 of the second purification treatment means 300 and the support plate 310 on which the fine holes are formed, so that the second foreign matter is filtered. It is moved to 114. The sewage moved to the second accommodation chamber 114 as described above is passed through the fluid filter medium 410 and the string material 420 of the third purification treatment means 400 while the microorganisms are filtered in the third storage room 116. Is moved to). At this time, the foreign matter is filtered more effectively by the ion generating plate 430 installed between the fluidized bed material 410 and the string material 420. That is, since the foreign matter mixed in the sewage is mostly positive, the negative ions generated in the mobile generating plate 430 are combined, and thus are effectively adhered to the string-like media.

As described above, the fine water is further refined by the fourth purification treatment means 500 in which the sewage from which foreign substances are filtered while passing through the third purification treatment means 400 in the second accommodation chamber 114 is installed in the third accommodation chamber 116. Foreign object is filtered out. That is, the sewage that is moved to the third accommodation chamber 116 is floated to the upper portion and the foreign material by the upper and lower plates (510a, 510b) formed with micropores and sewage pipes 520 formed with micropores installed therebetween. Filtered In particular, foreign matters are attached to the filter medium 524 installed to surround the sewage pipes 520, which are detached by the second automatic desorption facility 526, and the foreign matter transport path of the lower side through the foreign matter discharge hole 118a. Is moved to 118.

According to the present invention, by treating the foreign matter in the sewage to the sewage treatment plant several times through the sewage pipe can improve the efficiency of the sewage treatment plant and greatly prevent environmental pollution. In particular, the present invention has the advantage that when the first to third receiving chambers for installing the first to fourth purification processing means in two or more rows, a large efficiency can be obtained in a narrow space.
