<p>[Problem] To provide a sewage treatment system of a sewer pipe, which can accelerate the decomposition of organic matter contained in sewage in the sewer pipe. [Solution] By providing a suction means (6) for sucking in air outside a sewer pipe (1) and providing an air mixing means (8, 9) for mixing the air sucked in by the suction means (6) into sewage flowing through the sewer pipe (1), fresh air outside the sewer pipe (1), which was sucked in by the suction means (6), is mixed into the sewage by the air mixing means (8, 9), aerobic microorganisms contained in the sewage are activated by the air, the decomposition of organic matter contained in the sewage in the sewer pipe (1) can be accelerated, and the long sewer pipe leading to a sewage treatment plant can be used as a sewage treatment system.</p> |
