The invention discloses a high-efficiency composite functional filler and a preparation method thereof, and the high-efficiency composite functional filler comprises a polymer filler and microbial bacteria accounting for 0.1-2% of the total weight of the polymer filler, the polymer filler comprises the following raw materials in parts by weight: 50-80 parts of high-density polyethylene, 20-50 parts of linear low-density polyethylene, 1-5 parts of a polyethylene foaming agent, 1-5 parts of liquid paraffin, 1-5 parts of a nucleating agent, 0.1-1 part of iron powder, 0.1-1 part of aluminum powder, 0.2-2 parts of activated carbon and 4-10 parts of diatomite. The advantages of physical adsorption and biological treatment are combined, the wastewater treatment efficiency can be improved, the concentration of pollutants such as organic matter and ammonia nitrogen is reduced, meanwhile, certain environmental friendliness is achieved, the wastewater treatment efficiency can be remarkably improved, ammonia nitrogen is
