Sewage tank, scrubber, control method and device of scrubber and storage medium

The invention discloses a sewage tank, a scrubber, a control method and device of the scrubber and a storage medium, and relates to the technical field of scrubbers. The sewage tank comprises a tank body, a first detection electrode, a second detection electrode, a cleaning mechanism and a control module, the first detection electrode is mounted in the box body; the second detection electrode is mounted in the box body; the cleaning mechanism is mounted in the box body; the control module is connected with the cleaning mechanism; the control module controls the cleaning mechanism to ascend and descend along the first detection electrode and the second detection electrode so as to remove attachments on the first detection electrode and the second detection electrode. According to the technical scheme, the cleaning mechanism is controlled by the control module to do lifting motion, so that attachments on the first detection electrode and the second detection electrode are removed, the situation that the electro
