Filtration dehydration apparatus

A filtration dehydration apparatus, comprising:

• a filter, composed of a filtration layer and an absorption layer while allowing a surface of the filtration layer that is orientated opposite to the absorption layer to be a first side of the filter, and allowing a surface of the absorption layer that is orientated opposite to the filtration layer to be a second side of the filter;
• a supporting structure, for supporting and fixedly securing the filter;
• a solid collector, for collecting any solid object left on the first side;
• and
• an extrusion unit, for pressing the absorption layer so as to squeeze liquid containing in the absorption layer out of the same;
• wherein, the first side is provided for a solid-liquid mixture to be placed thereon for allowing the liquid containing in the solid-liquid mixture to flow into the absorption layer through the filtration layer while enabling any solid object in the solid-liquid mixture to be filtered out and thus left on the first side.
