Sludge treatment is an important part of the ecological and environmental engineering major. By filtering the sludge to reduce its water content, some harmful substances in the sludge can be removed.

9. A plate and frame filter press method for sludge treatment, characterized in that: The following steps are involved: The hydraulic press (11) is controlled to operate, and the output end of the hydraulic press (11) pushes the membrane filter plate (7) located on the far right to move leftward, thereby closing the plurality of membrane filter plates (7), injecting sludge into the membrane filter plates (7) through the feed pipe (10) on the sludge pump (9), and the hydraulic press (11) squeezes the plurality of membrane filter plates (7) to perform filter pressing on the sludge, thereby reducing the water content of the sludge.
