Abstract: PURPOSE: Provided is an excess sludge treatment system by sonication in biological nutrient removal process, which is capable of minimizing sludge production, converting the sludge to carbon source to be reused, and improving sludge settling property by applying ultrasonic to raw wastewater and sludge. CONSTITUTION: The system comprises an anaerobic zone, an anoxic zone(2), an aerobic zone(3), a sedimentation zone(4), a sludge return pipe(6,7), and an ultrasonic reaction tank(5) for converting contaminant in wastewater to easily decomposable material by applying ultrasonic to wastewater, wherein the ultrasonic reaction tank includes a tank with no joining parts or reinforced joining parts, and an ultrasonic generator installed in the tank, and a plurality of oscillators, wherein the treated water of the ultrasonic reaction tank is transferred to the anaerobic zone, the anoxic zone(2) and the aerobic zone(3).
