Disclosed is a sewage treatment plant which treats sewage including a large amount of excreta and has a compact structure. The sewage treatment plant, according to the present invention, comprises: a first tank (10) which has multiple sensing members (S) for sensing a water level and a high water level alarm member (H) formed on the uppermost sensing member; a first pump (20) which is started when a water level is sensed by the sensing member (S) located under the high level alarm member (H) and is stopped when the water level is sensed by the sensing member (S) located in the lowermost part of the first tank (10); a first control part (30) which is started or stopped according to the operation of the first pump (20); an electrolysis device (40) which allows sewage discharged from the first tank (10) and seawater discharged from a seawater inlet line (C) to flow thereinto; a second control part (50) which is started or stopped according to the operation of the first pump (20) and the first control part (30); a second tank (60) which has a filtering device (T), a low level alarm member (L) formed higher than the filtering device (T), multiple sensing members (S) formed on the low level alarm member (L) to sense a water level, and a high level alarm member (H) formed on the uppermost sensing member (S); and a second pump (70) which is started when the water level is sensed by the sensing member (S) formed under the high level alarm member (H) of the second tank (60) and is stopped when the water level is sensed by the sensing member (S) formed on the lower level alarm member (L) of the second tank (60). |
