The utility model discloses a light porous ceramic ball for aquatic biochemical filtration, which comprises a ceramic body, micron-sized holes of 1-100 microns are fully distributed in the ceramic body, millimeter-sized holes of 0.1-10 mm are fully distributed in the surface and the interior of the ceramic body, the apparent density of the ceramic body is 0.4-1.5 g/cm < 3 >, and the ceramic body can be spherical or hollow spherical. By arranging the millimeter-scale holes and the micron-scale holes, the surface area and the water resistance of the ceramic body can be greatly increased, so that the ceramic body has sufficient contact time with water flow; in addition, the permeation speed of water is greatly increased, so that nitrifying bacteria and other beneficial protozoa attached to the whole ceramic body can be fully supplied with oxygen, mass propagation is achieved, hazardous substances such as waste in water are decomposed into harmless substances, and the efficiency of biochemical ...
