Further, the sludge is clamped between the upper and lower net belts, and is gradually extruded under the action of small to large force and shearing force through the wedge-shaped pre-pressing area, the low-pressure area and the high-pressure area so as to achieve the purposes of separating the sludge from the water and forming a filter cake, and the separated sludge is mainly treated in the process so as to realize the requirement of environmental protection.

secondly, the sludge flows into the resistance systems (120, 130) in the unidirectional flow box body (100), and is dispersed into a plurality of sludge flows under the action of a screen type resistance surface formed by the resistance systems (120, 130);
step three, spraying a flocculating agent by a spray head, and fully mixing the flocculating agent with the sludge flow;
and fourthly, precipitating the sludge mixed with the flocculant in a precipitation box body (300) to separate the sludge from the clarified water.
