Abstract

PURPOSE: To lower the flow speed of the downstream side in a precipitation tank as well as to attain to promote solid-liquid separation by collecting a floated substance under suction by providing a filter machine to the inside of the secondary treatment precipitation tank so as to be submerged under the water level of said precipitation tank.
CONSTITUTION: Raw water flowed into a precipitation tank from an inflow weir 2 is flowed while floated substances are precipitated therein and impinged to the wall surface 5 of a downstream side to be turned to a rising stream but, because a filter body 8 is sunk in the sewage 6 within the precipitation tank 1 so as to discharge the sewage 6 to the outside of the precipitation tank 1 by a suction pipe 10, a pump 9 and a discharge pipe 11 through the filter body 8, the flow speed of the rising stream at the wall surface is reduced and, by this phenomenon, floated substances 7 precipitated to the vicinity of the bottom surface of the precipitation tank 1 is prevented from being floated again as well as drift floated substances 7 are collected by the filter material of the filter body 8. In this case, the filter body 8 is formed by packing the space between double cylinders formed of a net like material with a particulate filter material and suction is applied from the nside thereof to the outer periphery thereof.
