SLUDGE REDUCING APPARATUS AND SEWAGE TREATING SYSTEM EQUIPPED WITH THE SLUDGE REDUCING APPARATUS

摘要

PPROBLEM TO BE SOLVED: To provide a system for efficiently reducing excessive sludge produced in the treatment of organic sewage. PSOLUTION: The sludge fed by a transfer pressurizing pump 2 is allowed to pass through a shock wave generator 6 which is provided with two opposed funnels and an impact plate disposed on an outlet part, thereby, is solubilized by the cavitation effect and the solubilized sludge is returned to an aeration tank and is biologically decomposed. Further, the solubilizing apparatus exhibits excellent energy-saving effect which permits the use of a relatively low pressure pump by combination with a pressurizing controller 7.
