The general dehydration efficiency is 60 percent.
The principle of the belt filter press is that after concentrated sludge and a flocculating agent with a certain concentration are fully mixed in a static mixer and a dynamic mixer, tiny solid particles in the sludge are aggregated into flocculent lumps with larger volume, meanwhile, free water is separated, the flocculated sludge is conveyed to a filter belt for concentrating gravity dehydration, the free water is separated under the action of gravity to form sludge in a non-flowing state, then the sludge is clamped between an upper mesh belt and a lower mesh belt, and the sludge is gradually extruded under the action of small-to-large extrusion force and shearing force in a wedge-shaped prepressing area, a low-pressure area and a high-pressure area to achieve the maximum separation of mud and water, and finally, a filter cake is formed and discharged. The core of the method is to dynamically extrude the filter material on the mesh belt and continuously separate solid from liquid. The disadvantages are small dynamic pressure, low dehydration rate and general dehydration efficiency of 60%.
