We studied the possibility to produce solid fuel using cattle manure and to apply TAO (Thermophilic Aerobic Oxidation) process of solid-liquid separation fraction. The physiochemical compositions of cattle manure solid fuel chip were analyzed as water 0.12%, low calorific value 3,510 kcal/kg, ashes 11.9%, chlorine 0.82%, sulfur dust 0.5%, mercury non-detection, cadmium 1.0 mg/kg, lead 2 mg/kg, arsenic non-detection. In treating cattle manure with TAO reactor the internal temperature of the reactor was increasing higher and $50^{\circ}C$ and over was maintained after 20 hours on. The physiochemical compositions of liquids increased from pH 7.3 to pH 9.18 and EC decreased from 4.6 to 3.48 mS/cm in treating process of cattle manure with TAO reactor. COD and SCOD decreased from 16,800 to 10,400 mg/L, from 4,600 to 2,040 mg/L respectively, which showed about 38% and 56% of remove efficiency respectively.
