NOVELTY - The processing facility (1) has storage tank (13), ultrafine-formation unit (5d), aerator (15), ferment-microbe supplier (5), sedimentation tank (16), post processor (17), and biological-treatment unit (18). Unit (5d) generates ultrafine material of the sewage cluster and returns to the storage tank or a mixing vessel (14). The aerator receives the ultrafine-processed sewage and ferment microbe from the mixing vessel, and carries out aeration processing. The biological-treatment tank biologically treats the sludge from the sedimentation tank.    USE - For treating sewage, purification-tank sludge, and livestock excrement.    ADVANTAGE - The processing facility efficiently processes floating organic matter and sludge with a ferment microbe by high-speed ultrafine formation. The sewage-treatment capability is improved sharply, and the final sludge amount is made zero. Generation of bad smell is suppressed by the zymosis of ferment microbe. The supernatant water is processed efficiently into treated water having controlled biological oxygen demand and chemical oxygen demand to be discharged into rivers. The condensate of the water vapor generated can be utilized as service water in factories. The flow rate of water in the annular flow path is maintained easily.    DETAILED DESCRIPTION - The processing facility (1) has a storage tank (13), an ultrafine-formation unit (5d), an aerator (15), a ferment-microbe supplier (5), a sedimentation tank (16), a post processor (17), and a biological-treatment unit (18). The storage tank receives supply of sewage containing drainage human waste and purification-tank sludge. The sewage sucked with a high-pressure pump from the storage tank is supplied to an annular flow path at high speed. The ultrafine-formation unit of high-speed water flow generates ultrafine material of the sewage cluster and returns the ultrafine material containing micron-level organic matter to the storage tank or a mixing vessel (14) as ultrafine-processed sewage by shearing action. The aerator receives direct supply of the ultrafine-processed sewage and ferment microbe from the mixing vessel, and carries out aeration processing through the mixing vessel. The ferment-microbe supplier supplies the ferment microbe to the mixing vessel. The sedimentation tanks separates the aerated sewage supplied from the aerator into supernatant water and precipitate sludge. The post processor receives supply of supernatant water from the sedimentation tank, and discharges processed water. The biological-treatment tank receives and carries out biological treatment of the sludge supplied from the sedimentation tank.
