WASTE WATER TREATMENT APPARATUS

摘要

PURPOSE: To provide a waste water treatment apparatus equipped with a self- washing type treated water separator preventing the outflow of a carrier to a treated water outflow port. CONSTITUTION: In a waste water treatment apparatus, a drum 7 of which the circumferential surface is formed from a water permeable porous material and the treated water outflow pipe attached to the center part of one end surface of the drum so as to communicate with the interior of the drum 7 are made freely rotatable in such a state that the axes of the drum 7 and the pipe are horizontal and a treated water separator 6 wherein the jet orifices of spray nozzles ejecting high pressure water for separating the suspended substance bonded to the outer periphery of the porous material to the inside of the drum 7 are arranged above the surface of the water is installed in a treatment tank 1 fluidizing bacteria bonded carriers to biologically treat waste water so as to be sunk in water by 1/2-2/3.
