PURPOSE:To provide an oil preparation and decomposition device for sewage to be decomposed in the same tank without separating the oil content in the sewage from a kitchen or the like and without picking up the separated oil content out of the tank. CONSTITUTION:The inside of a container 1 provided with a flow inlet 5 and a flow outlet 6 for sewage is divided by a partition 2 to form a sedimentation chamber 3 and an oil decomposition chamber 4, and an opening 2a formed on the lower section of the partition communicates with the flow outlet by a drain pipe 8, while a communicating opening for communication of the sedimentation chamber with the oil decomposition chamber on the position of almost the same height as the flow outlet 8 is formed on a purifier device, which is set as a pretreatment tank for a combined purifier tank or a public sewage. The oil content separated into an upper layer of the sediment chamber is taken from a flow opening into the oil content decomposition chamber, decomposed by an aeration device or the like, and the sewage in a lower layer is fed into a purifier tank in the following process by a drain pipe. |
