Description

TECHNICAL FIELD [0001] The present invention relates to a sewage system for preventing the generation of odor,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewage system for preventing a malodorous divergence, and more particularly, to a sewage system for preventing a malodorous divergence from occurring, due to the free fall of sewage flowing into a sewer line or a manhole, .

Generally, the sewage line buried in the basement collects the sewage of the household, the sewage of the factory, and the rain in the rain, and supplies it to the sewage treatment facility.

Generally, odor generated in the sewer line is divided into source, source and source. The source of the odor is the sediment in the sewer line and the slurry layer of the pipe wall because odorous substances are generated. The origin of the odor is that the dissolved odorous substance in the water is diverted into the gas phase, and the divergence is caused by the turbulence factors such as the outflow in the sewer pipe and the level difference. The source of the odor is that the odorous substance in the atmosphere of the discharged sewage pipe is discharged to the outside through the rainwater receiver and the manhole connected from the sewage pipe.

In other words, the odor is generated from the sediments in the sewer line, the pipe wall and the sewage, and after the divergence, the odor is discharged to the outside through the rain gutter and the manhole. The odor in the sewer pipe is discharged to the outside through rain gutters, manholes, etc., and it is perceived to be an abominable facility because the sewer pipe is displeased to citizens.

Currently, people around sewage pipes, rain gutters, and manholes have a problem that mental stress is increased due to headache, vomiting, discomfort and aversion induced by the odor emitted from the sewer line, rain gutters, and manholes, and is adversely affected by the pleasant living of the residents . At present, complaints caused by stench of sewer lines, storm drains, and manholes are steadily increasing.

FIG. 1 is a view for explaining a phenomenon in which a malodor is emitted in a sewer line with a drop, and FIG. 2 is a graph showing a malodor generation characteristic in the sewer line.

1, hydrogen sulfide, which is a representative substance of odor, is introduced into the sewage pipe 3 connected to the septic tank 1 connected to the septic tank 1 and the sewage pipe 2 connected to the septic tank 1, It is diverted by the turbulence condition due to free fall on the bottom surface. In addition, the hydrogen sulfide diffuses from the odorous odor due to the turbulence induced by the free fall of the sewage flowing into the sewage receiver (2).

As a result, the sewage canal 2 or the sewage line 3 having free fall causes freezing of sewage, which causes the odor to be further radiated.

2 shows the characteristics of the odor generation in the sewage line. The influence of the odor generation by the pump type purification tank can be reduced by installing the odor reduction facility. However, the influence by the natural drop type purification tank and the box inlet (connection with the sewer line The influence of the sewage falling from the sewage discharge pipe 4 to the sewage pipe 3 is diverted directly in the sewage pipe 3, so that it is difficult to reduce odor. Therefore, it is necessary to study the prevention of bad odor by the natural bottom tank and box inlet. Further, researches are needed to prevent the odor from being diverted due to the free fall of the sewage flowing into the sewage receiver 2 from the septic tank 1 or the like.
