The invention belongs to the field of sewage treatment, and particularly relates to a sludge scraping device for sewage treatment, which comprises a bridge frame positioned above a sewage tank, wheel devices are arranged at the two ends of the bridge frame and positioned on the upper end surfaces of the two sides of the sewage tank, and the wheel devices are connected with a driving mechanism. The bottom of the bridge frame is connected with a sludge scraping plate in a vertically sliding mode through a vertical frame, the top of the sludge scraping plate is connected with a lifting device through a vertical rod, and the lifting device is installed on the bridge frame. Therefore, the situation that the sludge scraping plate is lifted upwards when the sludge is thick and the resistance is large is avoided, and the situation that the bottom of the sewage tank cannot be touched when the sludge is thick can be avoided, so that the frequency of repeated sludge scraping can be reduced, and the sludge scraping effic
