The present invention relates to a settling facility which is a physical treatment facility of a water purification facility including sewage treatment plants and nonpoint pollution reduction plants. A partition wall (21) is installed inside a settling tank (10) for partitioning the inner space, which extends a flow path of processed water in the settling tank; hence, the settling efficiency is improved. Multiple traps (30) comprising a housing (31) and a precipitation tank (32), are built in the settling tank (10), and the collection of precipitated sludge is facilitated while unnecessary floatation of the sludge is suppressed, by separating the traps (30) from a lower plate (14) of the settling tank (10). |
