The treatment system comprises a water yield regulating pond, an EGSB (Expanded Granular Sludge Bed) anaerobic reactor and a tower-type biological filtering pond which are sequentially connected in series, wherein a mechanical agitator is arranged in the EGSB anaerobic reactor; the partial effluent of the EGSB anaerobic reactor is sent to the bottom of the EGSB anaerobic reactor in a pump exhausting manner so as to perform internal reflux; the reflux water is controlled by controlling the opening / closing and the opening degree of the valve; the reflux water is fed into a water distributing pipe which is positioned at the bottom of the EGSB anaerobic reactor and connected with a water distributor after the reflux water propels an impeller to rotate via the mechanical agitator. According to the system and the method, the treated wastewater can meet the requirement of 'Discharge Standard Of Pollutants For Livestock and Poultry Breeding' (GB18596-2001); the capital construction cost and the operating cost of wastewater treatment are lowered.
