Abstract
A floating sludge discharge device for a square settling tank, and belongs to the field of water treatment. In order to solve the problem of scraping of floating sludge in the square settling tank, by disposing a water outlet hole below a liquid level and designing a pulling barrel mechanism that changes its overall gravity by using secondary settlement water, to move up and down to pull a sludge scraping plate to move back and forth, the stretching-out end of the sludge scraping plate of a sludge scraping plate mechanism automatically goes deep into the liquid level and automatically lifts up when it returns.
