Embodiment Construction
[0024] The invention provides a combined method for improving the sludge dewatering effect of a membrane filter press, comprising:
[0025] a. to combine Figure 1~3 As shown, a grid pad 3 is laid on the outer side of each filter plate 1 of the diaphragm filter press, and the grid aperture of the grid pad 3 is smaller than the distance between two adjacent flow guide protrusions 2 on the outer side of the filter plate 1; as a preferred Yes, the grid aperture of the grid pad 3 is 1-2 mm, the thickness of the grid pad 3 is 1-2 mm, and the grid pad 3 is preferably made of corrosion-resistant and deformation-resistant materials, such as polypropylene;
[0026] b. Combine Figure 4 As shown, after the pressing of the diaphragm filter press, the blower is used to ventilate and purge the filter cake in the filter press; when ventilating and purging, a diagonally staggered purge method is used to make the vents and drains on different sides work in pairs. .
[0027] In this example...
