The invention relates to a method for treating fish-farming circulating water, which belongs to the field of aquaculture. The invention solves the problems that the equipment investment is large when a physical filtering method is adopted, and the effluent quality is unstable, the purification efficiency is low and no prophylactic measures for organisms exists when a fixed bed biological purification method is adopted in the existing fish-farming water treating method. The method of the invention is as follows: water discharged from a fishpond is precipitated in a settling pond and filtered in a valveless filter; a fluidized bed biofilter carries out biological cleaning on the filtered water; and after the anti-disease treatment and the ultraviolet sterilization thermoregulation treatment are carried out on the purified water, the water returns to the fishpond. Compared with the physical filtering method, the invested capital of the facilities of the invention is reduced by 30%-40%, the quality of the treated water is stable, no worker is needed for tilting table and cleaning, and the purifying efficiency is high. Since fossilized rhodobacter sphaeroides are adopted for preventing the fish from virosis, the capacity for fish is 2-3 times as much as that of a common circulating water fish-farming system, the survival rate of the fishes reaches to 95%-98%, the saved water resource reaches more than 90%, thus the method of the invention can be applied to the field of the aquaculture.
