The invention discloses a hollow ceramic filter ball, which comprises a ball body.The spherical body is a porous structure with a plurality of micron sized pores, and a hollow cavity is formed inside the spherical body.Among them, the organism adheres to the pore structure and filters the water passing through the pore structure by biological treatment, and the pore structure includes a plurality of ceramic particles with nanoscale pore structure and filters the water passing through the pore structure by ion adsorption, while the concentration of water in the middle cavity is lower than that in the outside of the spherical body, so that the water outside the spherical body flows to the middle cavity for filtration.本創作係揭露一種中空陶瓷過濾球，其包含球狀本體。球狀本體為具有複數個微米級孔隙之孔隙結構，且球狀本體之內部形成中空腔體。其中，生物附著於孔隙結構而以生物處理方式過濾經過孔隙結構之水，且孔隙結構包含複數個為奈米級孔隙結構之陶瓷顆粒而以離子吸附方式過濾經過孔隙結構之水，而中空腔體內的水之濃度低於球狀本體外的水，而使球狀本體外的水往中空腔體流動以進行過濾。
