The invention discloses a filtering material for a round high-load biological filtering pool and relates to the field of biological filtering pool. The filtering material is prepared from the following raw materials in parts by weight: 320-360 parts of honeycomb-shaped polypropylene foaming material, 12-20 parts of modified active carbon, 3-5 parts of nitrogen pentoxide, 8-10 parts of dicumyl peroxide, 4-5 parts of monoalkoxy titanate, 20-40 parts of modified phenolic resin, 10-20 parts of dibutyl hydroxy toluene, 10-15 parts of sodium acetate, 8-10 parts of 2-methyl-5-vinyl pyridine, 2-3 parts of potassium dihydrogen phosphate, 5-7 parts of calcium carbonate, 6-8 parts of sodium dodecyl sulfate and 6-8 parts of sweet potato starch. The filtering material disclosed by the invention has thebeneficial effects that a matrix is large in specific surface area and high in porosity, the bonding property of the raw materials is strong, the sewage-purifying effect is good, the service life isprolonged and the purification cost is saved.
