WASTE WATER TREATMENT INSTALLATION HAVING ULTRASONIC CAVITY FOR TREATING WASTE WATER CONTAINING ORGANIC SLUDGE

摘要

PURPOSE: A wastewater treatment device equipping with an ultrasonic wave hollow for processing the wastewater including the organic sludge is provided to install the ultrasonic generator in a circulating pipe with the ultrasonic wave hollow thereby reducing abrasion influence of the sludge about the ultrasonic generator. CONSTITUTION: A sludge is digested in a digestion tank(110,111). A circulating pipe(125) is installed in the digestion tank. The sludge of the digestion tank is circulated through the circulating pipe. A tube-type ultrasonic cavity(130) is installed in the circulating pipe. An inlet faces a bottom part from the upper part of the ultrasonic cavity.
