And in the third stage, clarification is carried out, the section of the tank body in the clarification area 10 is the largest, so that the upward flow velocity is the slowest, and the settlement of alum blossom is facilitated. And in the fourth stage, filtering is carried out, wherein a filtering area 11 adopts anthracite coal with the diameter of 1.2-1.8 mm and quartz sand with the diameter of 0.5-1.0 mm to form a double-layer filtering material filtering area, so that the clarified water is further filtered by a filtering material layer. Finally, the filtered water is discharged to an external clean water tank through a clean water pipe 12.
During the operation of the high turbidity purifier, sludge is continuously increased, the sludge settled after condensation overflows into the central sludge discharge barrel 13, enters the sludge concentration chamber 15 through the sludge radiation pipe 14 below the central sludge discharge barrel 13 for settlement, and after certain sludge concentration and working period are reached, the sludge discharge valve is opened immediately to discharge sludge to the sludge collection pool arranged outside.
