The sewage treatment apparatus 100 of the present invention configured as described above separates sediments and suspended matters contained in sewage using a vortex casing, and then purified water is discharged into a stream, and the sediment and suspended matters sewage through a drain pipe 113. The process is as follows.

First, in a rainy or rainy season, wastewater flows through various pipelines and pipe systems, and the wastewater flows into the reservoir 111 of the casing 110 through the inflow pipe 101.

At this time, the sewage flows along the circular wall surface of the casing while passing through the sewage inlet pipe 101 connected in the tangential direction of the casing 110. As this phenomenon continues, a vortex occurs, and the pollutants contained in the sewage are outside the vortex. Or moved to the center and separated.

In other words, when a vortex occurs, the weight of the sediment or suspended matter sinks to the center of the vortex, partly sinks, and some floats to the outside of the vortex to rise and float to the wall side of the casing.

Of course, the pollutants that collect and sink in the center of the vortex are discharged to the sewage treatment plant through the drain hole 113 and the drain pipe 114.

As the water level continues to increase in the state in which the contaminants are separated by the vortex phenomenon and reaches the induction pipe 130, the purified water is discharged to the discharge part 150 through the outlet 131 along the inclined pipe 141. do.

Purified water leaked to the discharge portion 150 is discharged to the river through the outlet 152 along the inclined cover plate 121.

When the inflow of sewage is excessive and passes through the capacity of the reservoir 111, the sewage is discharged to the outside through the over-plued pipe line 140 installed at the center of the induction pipe 130 to control the water level. Of course, at this time also through the vortex, and the filtering net 143 installed in the straight body 142 is purified and discharged sewage.

On the other hand, when the rain stops and the inflow of sewage is reduced, the centrifugal force also decreases gradually, and contaminants gathered outside the vortex gradually sink to the center and are discharged through the drain pipe 114.
