SUCTION SEWAGE TREATMENT EQUIPMENT AND CONTROLLING METHOD OF THE SAME

摘要

The present invention relates to a sewage treating device. The sewage treating device according to the present invention comprises: a toilet bowl (100); a sewage treating tank (600) for treating sewage; and an intermediate suction tank (200) for sucking sewage in the toilet bowl (100) and discharging the sewage to the sewage treating tank (600). The intermediate suction tank (200) includes: a chamber (210); a membrane plate (220) for dividing the chamber (210) into a suction chamber (211) and a pressurizing chamber (212); and an elastic member (230) arranged in the suction chamber to pressurize the membrane plate (220) toward the pressurizing chamber (212). A sewage introducing pipe (240) connected to the toilet bowl (100) is connected to one side of the suction chamber (211), a sewage discharge pipe (250) connected to the sewage treating tank (600) is connected to the other side, and an air introducing pipe (260) for introducing air for pressurizing the membrane plate (220) toward the suction chamber (211) is connected to the pressurizing chamber (212).
